PUERTO RICO AND THE RIGHT OF ACCESSION

Joseph Blocher & Mitu Gulati*Estados Unidos

Abstract

On June 11, 2017, Puerto Rico held a referendum on its legal status. Although turnout was low, 97% of ballots favored statehood, rather than independence or the status quo. The federal government, however, has financial and political reasons to resist this preference: Puerto Rico would bring with it a massive, unpayable debt,

PROCLAMA CUARTEL GENERAL DEL EJERCITO DE LOS ESTADOS UNIDOS PONCE, PUERTO-RICO JULIO 28 1898 ¡A LOS HABITANTES DE PTO. RICO! Como consecuencia de la guerra que trae empeñada contra España el pueblo de los Estados Unidos por la causa de la Libertad, de la Justicia y de la Humanidad, sus fuerzas militares han venido a ocupar la isla de Puerto-Rico. Vienen ellas ostentando el estandarte de la Libertad, inspiradas en el noble propósito de buscar a los enemigos de nuestro país y del vuestro, y de destruir o capturar a todos que resistan en las armas. Os traen ellas el apoyo armado de una nación de pueblo libre, cuyo gran poderío descansa en su justicia y humanidad para todos aquellos que viven bajo su protección y amparo. Por esta razón, el primer efecto de esta ocupación será el cambio inmediato de vuestras antiguas formas políticas, esperando, pues, que acepteis con júbilo el Gobierno de los Estados Unidos. El principal propósito de las fuerzas militares americanas será abolir la autoridad armada de España y dar al pueblo de esta hermosa Isla la mayor suma de libertades compatibles con esta ocupación militar. No hemos venido a hacer la guerra contra el pueblo de un país que ha estado durante algunos siglos oprimido, si no, por el contrario, a traeros protección, no solamente a vosostros si no también a vuestras propiedades, promoviendo vuestra prosperidad y derramando sobre vosotros las garantías y bendiciones de las instituciones de nuestro Gobierno. No tenemos el proposito de intervenir en las leyes y costumbres existentes que fueran sanas y beneficiosas para vuestro pueblo, siempre que se ajusten a los principios de la administración militar, del orden y de la justicia. Esta no es una guerra de desvastación, si no una guerra que proporcionará a todos, con sus fuerzas navales y militares, las ventajas y prosperidad de la esplendorosa civilización. Nelson A. Miles. General en Jefe del Ejército de los Estados Unidos

and the potential to swing the current balance of power in Congress. That then raises the two questions of whether Congress could decide expel Puerto Rico (give it “independence”) or is legally required to give it statehood (“accession”).

The answers are not obvious. International law, we argue, suggests that the people of Puerto Rico have a legal right to determine their own status vis-à-vis the mainland. Whether domestic law protects the same right of self determination is a more difficult question.

In 1998, Puerto Rico held a plebiscite about its status vis-à-vis the rest of the United States. For decades, voices both on and off the island had decried its status as an “unincorporated territory”—a legal category invented by a fractured Supreme Court in the widely-reviled Insular Cases a century ago,1 and not entirely clarified by the adoption of a constitution and “commonwealth” status in the 1950s.2 Broad dissatisfaction with this constitutional and political limbo—neither state nor territory; “belonging to” but not “part of” the United States;3 “foreign … in a domestic sense”4—might suggest that Puerto Ricans would want to resolve their colonial status by voting for independence. But of all the available options, independence proved to be the least popular: only 2.5% of voters preferred it, while 46.6% preferred statehood.5

Nearly twenty years later, Puerto Rico’s relationship to the rest of the United States is again in the headlines, and has again made its way to the Supreme Court. A June 2017 referendum found 97% support for statehood, but with only a quarter of eligible voters participating, it cannot be considered the final word.6 Moreover, that vote was cast in the midst of an extraordinary debt crisis. The island has something in the range of $70bn to $100bn in outstanding debt (depending on whether one includes unfunded pension obligations) and it is showing no signs of being able to pay off anywhere close to that amount absent external assistance.7La imagen puede contener: texto

Even as the significance of the debt crisis became clear throughout the spring and summer of 2016, the US Supreme Court handed down two decisions that effectively reaffirmed Puerto Rico’s colonial status.8 In one, the Court held that Puerto Rico could not take advantage of the same municipal bankruptcy options as

Puerto Rico’s debt crisis and its treatment at the Supreme Court add new urgency to resolving its relationship to the United States.11 It would be best, of course, for Puerto Rico and the federal government to agree on a new status. And just a few years ago, the President’s Task Force on Puerto Rico’s Status suggested that the President would follow the island’s lead: “The policy of the Federal executive branch has long been that Puerto Rico’s status should be decided by the people of Puerto Rico.”12 Some have suggested that such agreement is not only desirable, but necessary.13 The same Task Force, in fact, concluded that “if a change of status is chosen by the people of the [sic] Puerto Rico, such a choice must be implemented through legislation enacted by Congress and signed by the President.”14No hay texto alternativo automático disponible.

But what if agreement continues to prove impossible15 or, perhaps in response to recent developments, the situation deteriorates? In the wake of the debt crisis and the loss of the special federal tax status for corporations located in Puerto Rico,16 it seems plausible that Puerto Ricans have even more reasons to support

And yet the same factors might lead voters on the mainland to resist statehood, or even to push for independence as a way to avoid costly obligations.19 On the same day that the United States elected Donald Trump as President—a man who has, to put it mildly, been willing to question the existing legal order—Puerto Rico chose a governor for whom statehood is first and foremost on the agenda. If Puerto Rico’s new government were to demand statehood, could the Trump Administration say no? Or could Congress do the blocking, if, for example, the Republicans in power fear that giving two Senate seats and five House seats to Puerto Rico will result in a loss of control? More radically, could the United States do as Britain and the Netherlands have done with some of their colonies,20 and essentially mandate independence?21

21 One might dismiss the talk as idle, but economically motivated expulsions have been a topic of discussion in the context of recent economic crises. See, e.g., Rainer Buergin, Schauble Tells Lew He’d Gladly Swap Greece for Puerto Rico, BLOOMBERG BUSINESS, July 9, 2015 (“I offered my friend Jack Lew… that we could take Puerto Rico into the euro zone if the U.S. were willing to take Greece into the dollar union,” said Wolfgang Schauble at a Deutsche Bundesbank conference on July 9, 2015.

it.23 The United States is, like most countries, a product of cessions and transfers,24 and centuries of practice suggest that nations have total control over their own borders. Is there a newly developed principle of international law, or some domestic constitutional rule, that would prevent it today?

The answers to these questions suggest something deeper about the law of sovereignty. We argue that colonies in general, and the people of Puerto Rico in particular, have a legal right to determine their own futures vis-à-vis their colonial powers—whether that means pulling away or pulling closer.

This may sound sensible enough in light of long-standing domestic policy approving statehood and growing international support for the principle of self- determination. But identifying a firm basis for these conclusions in constitutional or international law requires more work than one might expect. Puerto Rico is not a state, and as Christina Duffy Ponsa has demonstrated, there is reason to think that the Insular Cases were written in part to preserve the government’s option to “de- annex” (i.e., expel) the island.25 The same, it turns out, is true of other American territories.26 The Philippines were acquired under the same treaty as Puerto Rico— decades later they were made independent, and the US nationality status of their residents revoked.27 What prevents the same from being done to Puerto Rico?

We begin from a different starting point, by asking whether international law has to say on the matter. International law has played a role in justifying Puerto Rico’s existing relationship with the rest of the United States. The initial relationship was the product of a conception of international law that allowed nations (particularly the imperial powers) to do what they wished with sovereign territory—steal from, sell, cede, or ultimately abandon—without the approval of the territory’s residents.28 The Insular Cases themselves invoked international law

regarding the legitimacy of western nations exercising authority over their less civilized colonial subjects while keeping them at arm’s length.29

But international law changed fundamentally in the aftermath of World War II, and the United States was a leader in urging the changes.30 In the post-1945 era, and under the United Nations charter and associated human rights treaties, it is no longer acceptable to treat former colonies as property. As part of this fundamental shift in the global order, the imperial powers were required to either let go of their colonies31 or, if those colonies wished, bring them closer. The latter option is less recognized, but is at the core of the right of self-determination that all peoples (and particularly former colonies) are supposed to have.32

The United States, therefore, had to choose to either give up its colonies or represent to the international system (the United Nations in particular), that the former colony was being given full rights of self determination. In economic terms, the U.S. had to decide whether to “make” or “buy” whatever value Puerto Rico was providing since “steal” was off the table.33 The U.S. could have decided to give Puerto Rico independence and entered into contracts with it for military bases (as it did with the Philippines and Cuba – the “buy” decision), but Puerto Rico was considered strategically important enough that the United States wanted full control and not just a contractual relationship (the choice was to “make” or incorporate).34 And the price of bringing Puerto Rico into the United States should have involved granting rights to the Puerto Rican people, both individually and collectively. Theoretically, this was done in 1952 when the United States entered into a “compact” with Puerto Rico, allowing it to have its own domestic constitutional structure, and simultaneously reporting to the United Nations that the law “expressly recognized the principle of government by consent.”35

See MARY ANN GLENDON, ELEANOR ROOSEVELT, A WORLD MADE NEW: ELEANOR ROOSEVELT AND THE UNIVERSAL DECLARATION OF HUMAN RIGHTS (2001).

Whether and under what conditions the United States can expel Puerto Rico, or continue to hold it at arm’s length, is partly a function of the compact’s terms.

Specifically, what was the implicit promise being made by the more powerful actor in the bilateral relationship to the weaker partner and to the international system? That implicit deal could not be that Puerto Rico could be kicked out of the Union at any point at the whim of the United States Congress, nor that it could perpetually be held at arm’s length. To the contrary, we argue, Puerto Rico has the right to demand that it be brought closer into the Union, and specifically that it be given statehood.

Part I provides a legal and historical overview of Puerto Rico’s status vis-à- vis the rest of the United States. Our focus is on the degree to which legal and political developments, including the Insular Cases, have arguably emphasized and preserved the United States’ authority to keep Puerto Rico at arm’s length, and even to expel it.

Part II turns to international law. Puerto Rico’s semi-sovereign status complicates the analysis. Whether one considers Puerto Rico to be an independent sovereign in a treaty with the mainland or something more like the property of the United States, traditional readings of international law would not prohibit expulsion.36 We argue, however, that contemporary international law requires that Puerto Rico’s wishes be taken into account. Indeed, the values underlying self- determination suggest that Puerto Ricans should have the ultimate say in whether to be more closely associated with the United States.

In Part III, we consider domestic constitutional limitations on either expelling Puerto Rico or denying it statehood. We conclude, as others such as Christina Duffy Ponsa have done,37 that the constitution does not clearly prohibit expulsion of unincorporated territories. And yet the constitution does not rule out the proposition that Puerto Rico has a right to demand statehood. That, in turn, raises questions about whether, if ever, a state could be expelled from the union.

The legality of expulsion is one of the central questions for the legacy of colonialism—of which Puerto Rico is one prominent part. Today, most colonies that have sought independence have received it.38 Conquest is no longer the central threat to self-determination and self-governance—international law and practice forbid it. What, then, of “reverse conquest”—the expulsion of a territory against its

POL. 422 (2012) (similar).

will? The harms might be similarly serious, especially for the millions of people living in former colonies who now benefit (comparatively speaking) from maintaining a relationship to the metropole. Do the constitutional principles against secession also prohibit expulsion? Can international law principles like self- determination be invoked against independence? In a world where sovereign territory no longer has the obvious value it once did, these are central questions for the law of sovereignty. The answer, we think, might be the right of accession.

I.  The Legal and Political Status of Puerto Rico

On February 15, 1898, the U.S.S. Maine exploded in a Cuban harbor. The fire and smoke over Havana that night helped inaugurate the Spanish-American War—a “splendid little war” fought nominally to secure Cuban independence from Spain,39 and which was over by Christmas of that year. In the Treaty of Paris, Spain ceded Cuba, Puerto Rico, Guam, and the Philippines to the United States.

In ways that are perhaps unimaginable today, the acquisition of these territories made empire a part of the American political consciousness, to the degree that “[t]he election of 1900 largely turned upon the so-called issue of Imperialism.”40 The end of the war cemented the United States’ status as a world power—never before and never since has it controlled so much territory.41 But while expansion was on the minds of many,42 the acquisition of Spain’s Caribbean and Pacific territories also raised the question of whether the United States could dispose of its new territories. As President McKinley put it in 1898: “While we are conducting war we must keep all we can get; when the war is over we must keep what we want.”43 For a variety of reasons, Cuba and the Philippines did not remain under American control. 44 Puerto Rico and Guam still are.

REV. 801 (1926)); Cabranes, supra note 8, at 4 (“The expansion of American power and influence precipitated a great national debate on imperialism, a debate that moved the nation for several years before and after the Spanish-American war and dominated the presidential election campaign of 1900.”).

It resulted essentially from the desires of some U.S. leaders to win a war, build a larger empire, and prove to the European powers that [white] Americans, too, were one of ‘the great masterful races,’ as the feisty Teddy Roosevelt put  it”).

Five remarkable articles published in the Harvard Law Review in 1898 and 1899 by luminaries like Abbot Lawrence Lowell, C.C. Langdell, and James Bradley Thayer45 helped lay the groundwork for the Supreme Court’s ultimate resolution of the issue.46 (None, of course, concluded that Puerto Rico’s status was for Puerto Ricans to determine.)

How striking, then, that the issue has so far receded from political and legal consciousness that most Americans probably cannot identify Puerto Rico’s status, let alone account for the United States’ other territories.47 The past decade has seen an increase in scholarly attention to Puerto Rico,48 but Sanford Levinson’s observation is likely still accurate: Most constitutional law professors are probably not familiar with the Insular Cases49—the foundational Supreme Court cases that, between 1901 and 1922, created the notion of unincorporated territorial status and relegated Puerto Rico to it.50 Though criticized from nearly all quarters, the cases still provide the foundation for the legal status of Puerto Rico,51 as last term’s Supreme Court cases demonstrate.52

  1. Annexation and the Insular Cases

The annexation of Puerto Rico following the Spanish-American War raised the question of the island’s status vis-à-vis the rest of the nation. Would it be a state, and its residents American citizens? Or would it be the property of the mainlanders? Would it, like Cuba (and, eventually, the Philippines), officially be given

independence? And, if none of the above, how long could the island be held in legal and political limbo?

In the immediate aftermath of annexation—which Puerto Ricans did not initially resist53—Puerto Rico’s political leaders preferred statehood.54 But in 1900, those hopes were dashed when Congress passed the Foraker Act,55 whose sponsor said it was designed “to recognize that Puerto Rico belongs to the United States of America.”56 The Act made clear that Puerto Rico was not only not a state, but was disadvantaged even vis-à-vis other territories. As Ponsa notes, “most significantly, Congress had declined to extend the US Constitution by statute to Puerto Rico, as it had done in all prior territories, and instead of granting US citizenship to the island’s inhabitants, it declared native-born Puerto Ricans ‘citizens of Porto Rico,’ a nebulous and undefined status that seemed to amount to little more than an embellished form of statelessness.”57

Questions of citizenship and statehood were intertwined from the moment of annexation.58 Article IX of the Treaty of Paris took away the Spanish citizenship of the territories’ residents, but did not guarantee U.S. citizenship. Instead, the terms of the Treaty simply provided that “[t]he civil rights and political status of the native inhabitants of the territories hereby ceded to the United States shall be determined by the Congress.”59 This was potentially a significant change, since Puerto Ricans had been entitled to rights in the Spanish system,60 and it was the first time that “in

In 1916, Puerto Rico’s resident commissioner, Luis Muñoz Rivera, articulated a position held by many of the island’s political elites, by trying to connect citizenship and statehood: “Give us statehood and your glorious citizenship will be welcome to us and to our children. If you deny us statehood, we decline your citizenship, frankly, proudly, as befits a people who … will preserve their conception of honor, which none can take from them ….”63

The Jones Act of 1917 did eventually confer American citizenship on Puerto Ricans,64 and it was still “widely believed that it would only be a matter of time until this ‘transitory phase’ would end in statehood.”65 (Notably, a year before, the Jones Act of 1916 pledged eventual independence to the Philippines66—a promise that was fulfilled in 194667). But as Judge José Cabranes notes, “the citizenship that was granted was not complete,” and the “very word ‘citizenship’ suggested equality of rights and privileges and full membership in the American political community, thereby obscuring the colonial relationship between a great metropolitan state and a poor overseas dependency.”68 Cabranes concludes that “[b]y extending United States citizenship to the Puerto Ricans after promising independence to the

Filipinos, Congress intended to do little more than proclaim the permanence of Puerto Rico’s political links with the United States.”69

In addition to these shaky constitutional foundations,70 one must also note the degree to which the denial of full citizenship was a product of underlying racism.71 Justice Brown would later conclude: “Indeed, it is doubtful if Congress would ever assent to annexation of territory upon the condition that its inhabitants, however foreign they may be to our habits, traditions and modes of life, shall become at once citizens of the United States.”72

What is clear, however, is that Puerto Ricans’ citizenship has not been treated as equal to that of other Americans. In Balzac v. Porto Rico,73 for example, the Supreme Court held that the 1917 grant of citizenship to the island’s inhabitants did not change their constitutional rights, so long as they remained residents of the island. Chief Justice Taft concluded that the locality, and not their individual status as citizens, was what mattered.74  Taft’s views of Puerto Ricans and their rights seem to have been tinged with much the same kind of racism that would later infect the opinions in the Insular Cases.75

The Foraker Act also “dispensed with the free trade that had been the norm between US territories and states.”76 Trade restrictions inspired a legal challenge, which eventually worked its way up to the Supreme Court as Downes v. Bidwell, the first and most famous of the Insular Cases.

The central underlying legal issue in the Insular Cases is the one addressed in the five Harvard Law Review articles noted above. Four of those articles divided on the question whether territories were part of the “United States.”77 But the fifth, by future Harvard President Abbott Lawrence Lowell, took an approach that Ponsa and

Burke Marshall describe as falling “somewhere in between.”78 Lowell argued that it was up to the political branches to determine whether a territory should be incorporated into the United States, or merely acquired by it: “The incorporation of territory in the Union, like the acquisition of territory at all, is a matter solely for the legislative or treaty-making authorities.”79 Lowell’s description of something like a purgatory of sovereign status is close to what the Supreme Court ended up endorsing.

There is no straightforward way to state the doctrinal result of the Insular Cases. An oft-quoted summary comes from Justice White’s opinion:

The result of what has been said is that while in an international sense Porto Rico was not a foreign country, since it was owned by the United States, it was foreign to the United States in a domestic sense, because the island has not been incorporated into the United States, but was merely appurtenant thereto as a possession.80

This odd dichotomy—not foreign “in an international sense,” and yet “foreign … in a domestic sense”—is captured by two of the decisions that made up the Insular Cases. In Downes, the Court effectively held in a splintered set of decisions that the Uniformity Clause (which requires uniform “duties, imposts, and excises …. throughout the United States” 81) does not apply to Puerto Rico. This suggested that the island is indeed “foreign.” And yet in De Lima v. Bidwell, the Court held that Puerto Rico did not fall within the scope of the Dingley Act, which provided for duties on goods shipped to the United States from “foreign countries.”82 This reinforced the notion that Puerto Rico was not foreign in an international sense.

There is much more to the Insular Cases than this, and—beginning with the Justices in Downes—people continue to disagree about whether, for example, the Supreme Court held that the federal government can exercise power extraterritorially without being subject to constitutional restrictions. (To take one example, the Court is currently considering Hernandez v. Mesa, regarding the application of the Fourth Amendment to a cross-border shooting.83) The cases are often said to stand for the proposition that the Constitution does not “follow the flag”—basically true as far as it goes, but also misleading. A better statement might be that Downes says the constitution does not entirely or necessarily follow the flag.84

84 Contrast Justice Brown’s suggestion that certain “prohibitions as go to the very root of the power of Congress to act at all” Downes, 182 U.S. at 277 (Brown, J.), with Justice White’s conclusion that “the question which arises

With regard to territorial status itself, one initial question is whether that status can be maintained indefinitely, or whether it must ultimately be resolved one way or the other—into statehood or independence, for example. In the Insular Cases, the Supreme Court suggested two answers to that question, depending on the kind of territory at issue. “Incorporated” territories are on their way to statehood and, hence, subject to the restrictions of the Constitution. “Unincorporated” territories like Puerto Rico, however, are not—they lack many basic constitutional protections, but also a constitutional trajectory. As Chief Justice Fuller put it in his dissent, “the contention [of the majority opinion] seems to be that, if an organized and settled province of another sovereignty is acquired by the United States, Congress has the power to keep it, like a disembodied shade, in an intermediate state of ambiguous existence for an indefinite period.”85

Puerto Rico is not the only example within in the United States. The Northern Mariana Islands, Guam, the U.S. Virgin Islands, and American Samoa are also unincorporated territories,86 and together they cover more such territory “than is controlled by any other country in the world.”87  As Ponsa and Marshall note:

Although each of the U.S. territories has a different status … they have several features in common: Congress governs them pursuant to its power under the Territorial Clause of the U.S. Constitution; none is a sovereign independent country or a state of the Union; people born in the territories are U.S. citizens, or, in the case of American Samoa, U.S. “nationals”; all are affected by federal legislation at the sole discretion of Congress; none has representation at the federal level.88

The uninhabited atoll of Palmyra “enjoys the curious distinction of being the only American jurisdiction outside the fifty states and the District of Columbia to which the U.S. Constitution applies ‘in its entirety.’ This is because Palmyra possess a unique legal status within the framework of U.S. law: it is the only ‘incorporated’ territory of the United States.” Christina Duffy Burnett, The Edges of Empire and the Limits of Sovereignty, in LEGAL BORDERLANDS: LAW AND THE CONSTRUCTION OF AMERICAN BORDERS (Mary L.

inhabitants.”89 They therefore can “belong to” the United States without being part of it.

An analogous series of developments took place in international law at roughly the same time as the Insular Cases were reshaping US law. Martti Koskenniemi has noted that in the decades surrounding World War I—the last time that colonial expansion was truly prominent and open—some nations hesitated to officially extend sovereignty over territories.90 As one critic put it, “greed and the wish for exploitation without administrative and policy costs had led European countries to employ hypocritical techniques of annexation without sovereignty.”91

The natural question to ask is why. Just as people are thought to have an innate desire for acquiring property, nations are generally supposed to prefer more sovereign territory, not less—the basic rules of international law and practice have evolved largely to address that expansionist impulse. Indeed, “[v]irtually all states and empires have treated territory as being of itself good,”92 and “[t]he history of international law since the Peace of Westphalia is in significant measure an account of the territorial temptation.”93

Why, then, would the United States choose to keep Puerto Rico at arm’s length? One important factor is that most nations powerful enough to maintain colonies are also powerful enough to exert control more cheaply and effectively without claiming sovereign territory,94 or even by explicitly disclaiming it.95 As Ponsa notes, “We tend to associate imperialism with the acquisition of territory, the projection of power, and the imposition of sovereignty. The emphasis tends to be on expansion—more territory, plenary power, extended sovereignty. Yet American imperialism has also consisted of efforts to impose limits on expansion.”96

An obvious cost of territorial expansion, and therefore a reason to avoid it, is the principle for which Downes is most commonly invoked: the extension of constitutional law. If incorporating Puerto Rico—granting statehood, for example— would mean that the island’s residents could claim the full panoply of constitutional

rights (including birthright citizenship97), and that the island itself would have more of a constitutionally-guaranteed role in the constitutional structure (senators and the like), the perceived “cost” to the rest of the United States might be high. By declining to treat Puerto Rico like a state, while also denying it a chance to affiliate with other nations,98 the mainland got to eat its cake without the calories.

Somewhat more radically, though, keeping Puerto Rico at constitutional arm’s length may have been designed to preserve the United States’ exit option— retaining the power to expel Puerto Rico; a prospect that would be much more difficult (and perhaps impossible99) if it were to become a state. On this interpretation, the significant thing about the Insular Cases is not how much sovereign control over Puerto Rico they approved, but how much they held back.

Ponsa’s pathbreaking work has demonstrated the degree to which Puerto Rico’s relationship to the mainland must be understood through the lens of the federal government’s power to control that relationship.100 Ponsa argues that it is wrong to understand the Insular Cases as holding that the Constitution does not “follow the flag.” Instead, the cases’ primary significance is that they “served the aims of empire in a different and unexpected way: not by opening the door to the annexation of American colonies, but by paving the way for their release.”101 Ponsa argues that the cases established that territories like Puerto Rico “could be separated from the United States, or . . . ‘deannexed,’ as long as they remained unincorporated. Preserving the option of deannexation was precisely the reason not to incorporate a territory in the first place.”102

This is much the same phenomenon that Koskenniemi observed in international law. Human rights lawyers in the 1920s and 1930s argued strenuously that colonies should be treated as fully subject to the sovereignty of their colonizers—not held as possessions.103 The latter was what happened in many contexts where the imperial power wanted to expropriate from the overseas

B.   Indeterminate Self-Determination

As a constitutional matter, the Insular Cases largely settled the status of Puerto Rico. And by the time the last of the cases was decided in 1921, the nation’s attention had largely turned away from the island.

But on the island itself, the question of status remains paramount and unsettled.106 In 1948, for the first time, Puerto Rico elected its own governor—Luis Munoz Marín, who would remain in power for nearly two decades at the head of the Commonwealth Party. As the name of his party suggests, Marín presided over Puerto Rico’s transition to “commonwealth” status. This transition was overwhelmingly approved by the residents of Puerto Rico—76.4% voted in favor— and surely inaugurated a new era. But its precise legal significance remains unsettled, leading to a series of plebiscites and referenda in the decades since.

In 1996, Representative Don Young (R-AK) introduced a bill to present the people of Puerto Rico with a range of options that Congress would be willing to accept. “Enhanced commonwealth” was not among them, however, which caused “immediate and overwhelming opposition on the island.”107 (The three options offered were statehood, commonwealth without “enhancements,” and independence.) The Young bill eventually died in the Senate, leaving Congress’s official position on the matter unresolved.108

Puerto Rico’s government (which favored statehood) responded by organizing a separate and nonbinding plebiscite in December 1998, which presented a slightly different list of options: independence, “free association,” statehood, non-enhanced commonwealth, and “none of the above.” Again, enhanced commonwealth status was omitted, leading Marín’s heirs in the Popular Democratic Party to advocate “none of the above.” In the end, 50.3% of voters did so, while 46.6% chose statehood and .06% supported the unenhanced commonwealth

option.109 The increasing support for statehood, however, was notable, and when Puerto Rico held another status quo plebiscite (its fifth) in 2012, received a plurality of support for the first time.110

On November 8, 2016, voters on the mainland chose Donald Trump as the next US President. (Puerto Ricans living on the island, although citizens, have no vote in the presidential election.) That same day, Puerto Ricans elected a new governor, Ricardo Rosselló. His New Progressive Party supports statehood (its main competitor, the Popular Democratic Party, does not), and on November 9 he called on President-Elect Trump to facilitate the move to statehood.111 Rosselló said that “[t]he Republican platform is very clear” in supporting statehood if Puerto Rican voters choose it, and that “having a Republican House (of Representatives), a Republican Senate and a Republican president, there’s no excuse for not carrying it out.”112

In keeping with his campaign promises, Rosselló’s party organized a nonbinding referendum to be held on June 11, 2017. Percentage-wise, the results were overwhelmingly supportive of statehood—nearly 97% of all votes cast. But only 23% of voters turned out to cast those votes, leaving the implications unclear yet again. The next day, the New York Times reported, “By law, the next steps toward statehood remain in Congress, where advocates for statehood face the daunting task of persuading a legislature dominated by Republicans to take on a state which would have the nation’s highest poverty and unemployment rates and an unpaid

$74 billion debt.”113 Whether those next steps are truly entrusted “by law” to Congress is among the central questions we address here.

  1. The Remarkable Resilience of the Insular Cases

In some respects, the turnaround with regard to Puerto Rico’s status has been remarkable. A century ago, the Harvard Law Review published five articles that, in different ways, defended the idea of American empire. Today one searches in vain for defenders of the Insular Cases.

But in other ways, the cases have not lost their grip. While the Court has overruled or minimized many other constitutional doctrines rooted in racism and a national self-conception that we would not tolerate today,114 the Insular Cases

114 Of the four cases Jamal Greene lists as constituting the “anticanon” of constitutional law, three fit this description: Dred Scott v. Sandford, 60 U.S. (19 How.) 393 (1857), Plessy v. Ferguson, 163 U.S. 537 (1896), and remain good law. The Supreme Court’s 2015-16 term provided a few prominent illustrations. 115

The first arose directly from Puerto Rico’s debt crisis. In Puerto Rico v.

Franklin California Tax-Free Trust,116 the Supreme Court held that the bankruptcy code provided no relief for Puerto Rico or its municipalities and yet also precluded Puerto Rico from enacting an insolvency regime of its own.117 Attempts to voluntarily restructure certain parts of the debt, while often showing initial glimmers of optimism, eventually fell apart.118 Puerto Rico was in fiscal purgatory.

Eventually, Congress generated something of a solution—one that, whatever its effectiveness, emphasizes Puerto Rico’s second class status. Specifically, Congress passed PROMESA, which opened the door to Chapter 9 of the Bankruptcy Code but with a steep price for Puerto Rico.119 A control board was put in place that effectively had control over the territory’s finances and conduct of any Chapter 9 type proceedings.120 It remains to be seen whether this last minute action is sufficient to save the island from economic collapse, but in any event the loss of sovereignty was a price that no state would ever be asked to pay.

The second major case from the term drove home Puerto Rico’s disadvantaged status. In Puerto Rico v. Sanchez Valle, the Court held that Puerto Rico, unlike a state, is not a “sovereign” for purposes of the Fifth Amendment’s Double Jeopardy Clause (which permits successive prosecutions by separate sovereigns).121 Writing for a six-Justice majority, Justice Kagan found that the events of 1950-52 created a “new political entity,” which was “republican in form,” and “subordinate to the sovereignty of the people of Puerto Rico.”122 But rather than creating a new sovereign, Congress’ enactment of Public Law 600 reflected Congress’ “broad latitude to develop innovative approaches to territorial governance.”123 And because Congress authorized and approved Puerto Rico’s Constitution, Congress was “the deepest wellspring[]” of Puerto Rico’s

See Pema Levy, Obama Administration Using Century-Old Racist Case Law to Block Citizenship, MOTHER JONES, Feb. 23, 2015 (quoting Sanford Levison as saying: “A lot of people are justifiably embarrassed by the Insular Cases because they really do capture an earlier imperial moment that is saturated in white supremacy”).

sovereignty.124 Therefore, Puerto Rico was not a “separate sovereign” from the United States, and successive prosecutions would violate the Double Jeopardy Clause.125

Justice Breyer, in dissent, questioned whether this was the proper inquiry, and even whether it leads to the conclusion that Justice Kagan reached. After all, states are only admitted to the United States on Congress’s say-so, but are clearly treated as separate sovereigns for purposes of the Fifth Amendment. Breyer would have looked to “the broader context of Puerto Rico’s history” to determine whether the island had “gained sufficient sovereign authority to become the ‘source’ of power behind its own criminal laws.”126 Among the most important moments in that history, of course, were the passage of Public Law 600 and the adoption of the Puerto Rican constitution, which—along with other evidence—Breyer concluded were sufficient to show separate sovereignty for purposes of double jeopardy analysis.127

Finally, although not directly involving Puerto Rico as a party, the Court denied certiorari in Tuaua v. United States. The parties in that case sought review of a D.C. Circuit decision upholding a 1900 law to the effect that people born in American Samoa are “nationals” who owe allegiance to the United States but— unlike people born in any of the 50 states, or even in territories like Guam and Puerto Rico itself—are not birthright citizens.128 This, the petitioners argued, violates the Fourteenth Amendment’s declaration that all persons “born or naturalized in the United States” are U.S. citizens.129

Perhaps not since the Insular Cases have the constitutional implications of colonialism been so central to the Supreme Court’s docket. And in last Term’s cases, the Justices essentially re-affirmed the status quo—one in which the people of territories like Puerto Rico and Guam have what can only be described as second class status. This Term, the Court will again grapple with the Insular Cases’ legacy, when it decides whether the Fourth Amendment applies to a cross-border shooting of an unarmed Mexican citizen in an enclosed area controlled by the United States.130

Most commentators on these developments see them as a continuation of Puerto Rico’s long-running subjugation,131 and with good reason. But in other ways,

things have changed. A century later, it seems plausible that Puerto Ricans might favor statehood at precisely the same time, and for the same reasons, that voters and politicians on the mainland oppose it. Puerto Rico is not treated as a “part of” the United States; perhaps the United States no longer wants it to be even that. The Supreme Court cases demonstrate the former; the political response suggests the latter. Indeed, some of the rhetoric surrounding the crisis indicates that many political leaders think of Puerto Rico as a distant, ne’er do well relation—but not as family.132

It is not our purpose here to further criticize the Insular Cases—it is not clear anyone is left to defend them.133 Judge Juan Torruella writes: “The Insular Cases were flawed when decided because they (i) directly clashed with our Constitution,

(ii) were disobedient to controlling constitutional jurisprudence in place at the time, and (iii) contravened without exception every single historical precedent and practice of territorial expansion since our beginning as a nation.”134 Yet the cases remain good law, giving Congress near-limitless power over Puerto Rico. Our interest lies with one particular aspect of that power—the power to deny statehood or even expel the island entirely.

II.  The International Law of Expulsion

The expulsion of a colony for financial reasons may seem far-fetched, but history tells us that this movie has played before. Imperial powers have given up territories—especially far flung ones—when economic conditions on the mainland were tough and the territory was expensive.

Newfoundland in 1930s and 1940s provides a ready example. By then it was the British Empire’s oldest colony, and had the status of a “self governing” dominion.135 But thanks to a combination of fiscal mismanagement and a drop in global fish prices in the 1930s, it found itself with an unsustainable debt stock.136 There were attempts to bring the situation under control—an imperial commission took control of governance for a period—but matters did not improve enough, and

133 Burnett & Marshall, Between the Foreign and the Domestic, in RECONSIDERING, supra note 8, at 2 (“No one today defends the colonial status sanctioned by these cases, yet the idea of a relationship to the United States that is somewhere ‘in between’ that of statehood and independence … has not only survived but enjoys substantial support.”).132 For discussions along these lines, see, e.g., Cate Long, Puerto Rico is America’s Greece, REUTERS, March 8, 2012; Greece in the Caribbean, THE ECONOMIST, Oct 2012; Gervasio Luis Garcia, I Am The Other: Puerto Rico in the Eyes of North Americans, 1898, 87 J. AM. HIST. 44 (June 2000) (noting that classifying Puerto Rico as an unincorporated territory meant “relegating the island to the perpetual status of a ward who will never become part of his patron’s family”).

World War II did not help.137 By 1946, faced with the prospect of having to invest in Newfoundland to get it on its feet, the British mainland decided that it would be better to give up Newfoundland to Canada, which was willing to take on 90% of the debt.138 The end result: Newfoundland essentially got expelled by the empire into the Canadian federation, with little or no say from the Newfoundlanders.

Finding guidance in international law is complicated as a threshold matter precisely because Puerto Rico’s current status is, as a matter of international law, debatable. If the compact between Puerto Rico and the rest of the United States is akin to a treaty between separate sovereigns, one set of international rules applies; if Puerto Rico is “part of” the United States, a separate set applies. We analyze each in turn, recognizing that these are not the only options, and that the island’s current status probably lies somewhere in between. The answers are not straightforward, but they suggest that the mainland does not have the exclusive and final word on Puerto Rico’s future.

A.    If Puerto Rico is a Separate Sovereign

Discussions of Puerto Rico’s status sometimes proceed as if it is already something like an independent nation—indeed, the United Nations’ Special Committee on Decolonization adopted a resolution criticizing violations of the island’s “national rights.”139

The piece of textual evidence typically used to suggest that Puerto Rico is sovereign is the phrase “in the nature of a compact,” which appears in Public Law 600. Supporters of the “compact theory” have long trumpeted this language as indicating that Puerto Rico and the rest of the United States entered into the agreement as something like equals, or at last co-sovereigns.140 This seems to be what convinced the United Nations General Assembly, which in November 1953 adopted a resolution recognizing that, under the compact, “the people of the Commonwealth of Puerto Rico have been vested with attributes of political sovereignty which clearly identify the status of self-government attained by the Puerto Rican people as an autonomous political entity.”141

140 It is possible to see this theory in existing First Circuit jurisprudence, at least before Sanchez Valle. See, e.g., United States v. Quinones, 758 F.2d 40, 42 (1st Cir. 1985) (stating that “in 1952, Puerto Rico ceased being a territory of the United States subject to the plenary powers of Congress”); accord First Fed.

Popular Democratic Party, 457 U.S. 1, 8 (1982) (“Puerto Rico, like a state, is an autonomous political entity, ‘sovereign over matters not ruled by the Constitution.’”).

141 OOSTINDIE & KLINKERS, supra note 12, at 47 (internal citation omitted).

U.S. Courts, including the Supreme Court, have written that Puerto Rico is “sovereign” in matters not governed by the U.S. constitution142—an admittedly ambiguous account. Some supporters of the constitution go farther, arguing that the nature of the “compact” suggested permanence—specifically, because it is essentially a treaty it can only be changed by the consent of both Puerto Rico and the rest of the United States.143

As a matter of international law, however, this is not true. Treaties often make explicit provision for withdrawal or expulsion (which, in the case of a bilateral treaty like P.L. 600 is alleged to be, are functionally equivalent). But even when they do not, the power to withdraw under certain circumstances is well established. The ability to effectively expel a state that has materially breached an international law obligation was codified the Vienna Convention on the Law of Treaties. Under Article 60 of the Vienna Convention, a “material breach” of a multilateral treaty by one party entitles “the other parties by unanimous agreement to suspend the operation of the treaty in whole or in part or to terminate it either: (i) in the relations between themselves and the defaulting State, or (ii) as between all the parties.”144

Are the rules different if one conceptualizes the exit from a treaty as an expulsion rather than a withdrawal? Not really. As with withdrawal, many treaties explicitly provide for suspension or even expulsion of members. 145

Even where those explicit provisions are absent, the best reading of background principles of international law suggests that there is an implicit right of expulsion if one party persistently breaches material terms of the agreement.146 Outright expulsion from international organizations is rare, but not unheard of. The Soviet Union was effectively expelled from the League of Nations in 1939 after it

invaded Finland147; Czechoslavakia was expelled from the International Monetary Fund in 1954 for refusing to provide data.148 And, as one might expect, the threat of expulsion is sometimes invoked to get members to behave.149

Recently, the question of expulsion has gained salience in the context of the Greek debt crisis. Frustrated by Greece’s inability to meet its obligations, and the fact that it apparently earned admission to the European Monetary Union on the basis of misleading numbers, the possibility of expelling Greece entirely from the Eurozone was raised.150

Some commentators have asserted that this is impossible, because the treaties do not make specific provision for such an eventuality. But, as we have shown, such an explicit power is not necessary. That does not mean that Greece should be expelled, nor even that its malfeasance rises to the level that would legally justify an expulsion. What it does mean, however, is that one cannot avoid those hard questions by simply concluding that expulsion is off the table.

Assuming that Puerto Rico is, like Greece, a separate sovereign, the situation is analogous in many ways. The precipitating event for contemplating expulsion is, in both cases, incipient bankruptcy and a massive debt crisis.

But as with Greece, this is not an argument in favor of expelling Puerto Rico. Expulsion on the basis of material breach seems to presuppose some degree of fault. And no one is claiming that the fault for the debt crisis lies all with Puerto Rico—or whether a debt crisis is the sort of fault that could justify expulsion. Indeed, as the Supreme Court’s decision last year made clear, Puerto Rico has been denied the options to tackle its own domestic debt crisis that state governments in the US have been long allowed (and there seems to be no logical reason for this151).  In the case of Greece, the alleged breach being discussed was very specific: Providing misleading numbers so as to ensure admittance to the monetary union in the first place. Nothing like that has happened in the case of Puerto Rico. Indeed, one might argue that its current dire straits are precisely the kind of unfortunate and unpredictable eventuality that leads to the creation of treaties, international organizations, and even nations in the first place. The obligation of the United States, whether as a treaty partner or the ultimate sovereign, is to provide the aid necessary to manage the crisis.

Finally, the very fact that Puerto Rico has been treated as a colony for so long should give it more, not less, control over its destiny. In that sense, the United States is the one in breach. That, we think, should give the island a different option: Not just to pull away from the mainland, but to push closer.

B.   If Puerto Rico is “Part Of” of the United States

The second way to see Puerto Rico is not as a separate “sovereign” akin to a foreign treaty partner, but as a part of the tighter compact that constitutes the United States. After all, Senate and House Reports both stated that “[Public Law 600] would not change Puerto Rico’s fundamental political, social, and economic relationship to the United States.”152 If that is the case, then the relevant question is whether a nation can excise a part of itself.

The question of whether a region can be expelled from a nation has not traditionally been asked.153 International law has long been obsessed with the sanctity and movement of borders, but it has generally assumed that the pressures that must be managed are either expansionist or secessionist.154 This has led to the emergence of two foundational but sharply divergent principles, the reconciliation of which presents a considerable challenge.

On the one hand, the traditional rules of sovereignty give states control over their own borders so long as they do not interfere with the borders of other nations. This means that nations can—and often have—ceded territory to others without the approval of the territory’s residents. Most of the United States, including Puerto Rico, was acquired in such a fashion.155

On the other hand, particularly in the past century, law and practice have given increased attention to the rights and interests of “peoples” to determine their own political destinies. The ascendant principle of self-determination provides that, in certain circumstances, a sub-national group or region can choose to secede, or to become a part of another nation. The circumstances under which this right can be invoked remain a subject of debate, but nearly everyone agrees that former colonies are the paradigm example.156

The possibility of expulsion of sovereign territory, and especially of colonies like Puerto Rico, confounds these rules in both directions. The traditional rules of

156 Karen Knop, A Market for Sovereignty? The Roles of Other States in Self Determination, OSGOODE HALL L. REV. (forthcoming 2017).

sovereignty would say that the United States has a nearly unfettered157 power to decide for itself whether to maintain Puerto Rico as a territory (subject to its own domestic restrictions, which are restrictive but not prohibitive).

But it is implausible to think that this traditional rule from the days of imperial power and conquest holds force today. International law no longer gives countries total authority to control their borders—even to cede territory voluntarily with another nation. If the right of self determination has any force, it cannot be the case that nations and buy, sell and abandon territory which has people on it without some strong showing of consent from those people. If those are the contours of the general rule, then what is the specific rule that would apply in the case of Puerto Rico?

Two characteristics of Puerto Rico’s situation are particularly notable. First, it is a former colony. Second, it transitioned from colonial status into self governance status specifically in the context of the shift in the international order from accepting imperial subjugation to rejecting that in favor of the right of self governance.

Take the general international law rules for colonies first. Traditionally, international law scholars tend to think of the colonial right to self determination as going only in one direction. In the cases of former colonies, that typically means exit from the colonial state in favor of independence. And in a context in which independence is clearly the preferred outcome for all of the citizens of the former colony, that makes sense—as was typically the case for many of the colonies who achieved independence in the mid 1900s.

But if the former oppressor is a rich state, with valuable citizenship rights, it is not clear that the people of the colony would prefer independence—particularly at the point in history when international law and global norms no longer countenance colonial oppression. And this, as we have seen through multiple votes over the past few decades in Puerto Rico, is the situation there. (Alex Aleinikoff has described Puerto Rico’s status as “colonialism by consent.”158) On the flip side of the equation, the preferences of the former colonial masters might also be different, now that the former colonial subjects have to be treated as equals. Now, granting them “independence” begins to look more attractive. Effectively, what we have is a

perverse kind of self-determination—de-colonization upside down.159 Instead of a right of secession from the mainland (the former imperial overlords), the question is whether there is now a right of accession to the mainland.

We think that international law, if forced to answer, would prohibit such an expulsion, for almost exactly the same reasons that it gives Puerto Rico a right to independence. Puerto Rico, a former colony, should have a right to decide to be more closely aligned with the mainland. And perhaps that right should accrue to every individual citizen. Put differently, the right to self determination of a former colony should (perhaps) negate the right to expel of the former oppressor (unless it pays to buy it out), but give the former colony all the rights of being an integral part of the parent/oppressor state. Whatever the deal regarding expulsion is with respect to those members of the union that voluntarily entered into it, surely the deal with the members who were coerced into joining should be interpreted in favor of the party coerced—then the rule on expulsion for states serves as something of a lower bound.

Although this conclusion is precisely contrary to the “direction” of most self- determination claims, it is nonetheless symmetric. International law has typically focused on expansion and secession, not expulsion, because those have historically been the forces that needed to be checked. But today, the former imperial powers face a different set of incentives. Physical territory is not so valuable as it once was, since natural resources are not so prominent as a source of national wealth.

Simultaneously, citizens are potentially more costly, since it is legally, politically, and morally more difficult to discriminate against particular groups of them, and the social safety nets provided by the former imperial powers are expensive to maintain.

What status should Puerto Rico be entitled to? Statehood? “Enhanced commonwealth” status? The menu is more complicated than one might suppose, even within the United States. Internationally, the range of possibilities is dizzying.160 We do not have answers to all of these questions. Our focus here is on who gets to make the decision, not what options are available. And as to the former question, we believe Puerto Rico has greater rights under international law than might currently be understood.

C.   The Domestic Relevance of International Principles

At first cut, international law may seem to be irrelevant to the question of whether Puerto Rico can be expelled from the United States. Surely no domestic court would think that it could counter a Congressional decision on such a matter by

160 See Blocher & Gulati, Forced Secessions, supra note 22.159 OOSTINDIE & KLINKERS, supra note 12, at 217 (“As far as Westminster was concerned, all of the former British colonies had to go. The fact that at present a handful of Caribbean ‘Overseas Territories’ still come under the sovereignty of the United Kingdom should not, therefore, be attributed to the ardent wishes of Westminster, but rather to the stubbornness with which these islands have refused to accept independence.”).

 

looking to international law to trump domestic legislative action. And indeed, the United States Court of Appeals for the First Circuit (which has jurisdiction over Puerto Rico) has said so in rejecting, on multiple occasions, the claim that human rights treaty obligations of the United States should mandate the grant of voting rights in national elections to inhabitants of Puerto Rico.161

There is a different way to come at the issue, though, which is to ask whether there is a different source of domestic law, one that may be informed by international law, that gives Puerto Rican citizens rights vis-à-vis the mainland.162 If there is, and the question is one of giving that source content, international law can be relevant. For example, the Constitution says that the citizens of the states have the right to vote for the President and for representatives in Congress. However, it does not prohibit citizens who do not reside in a state from being given the right to vote. So, the argument goes, if there was a treaty or equivalent legal source (a public law, for example) that the U.S. had entered into that granted that right, there would be no Constitutional bar on recognizing it.163

In such a context, a domestic court would not be drawing on international law to countermand domestic law, but rather determining the terms of an already existing domestic agreement. There is no dispute that such an agreement exists: Public Law 600 was explicitly represented to be a “compact” that would govern the future relationship between the United States and Puerto Rico. Given that the agreement has no explicit terms about expulsion, a court would have to put in place a default provision.

As a legal matter, the move to commonwealth status was set in motion by the passage of Public Law 600, “an Act to provide for the organization of a constitutional government by the people of Puerto Rico,”164 which provided for an insular referendum, which in turn overwhelmingly approved the creation of a constitutional convention.165 The draft constitution was approved by a public referendum in March 1952, and by Congress soon after. The statehood movement regained steam at around the same time.166

162 See Igartúa, 626 F.3d. at 609 (Lipez, J., concurring) (“If Puerto Rico residents’ right to vote originates from a source of United States law other than the Constitution, however, it is possible that declaratory relief could properly involve individual government officials rather than Congress.”).161 See Igartúa–De La Rosa v. United States, 417 F.3d 145, 147 (1st Cir. 2005) (en banc); Igartúa v. United States 626 F.3d 592 (1st Cir. 2010).

A quarter century later, Rubén Berríos Martínez, Puerto Rican senator, law professor and leader of the independence party, summarized the compact and its aftermath:

Twenty-five years ago the establishment of the Commonwealth of Puerto Rico was the official U.S. response to the worldwide process of decolonization. It was the “showcase of democracy” for colonial peoples and underdeveloped countries, the U.S. model of how a country could pull itself out of poverty “by its own bootstraps” through an intimate political and economic relationship with the United States. . . . By 1977, the Commonwealth of Puerto Rico has become a source of embarrassment to the United States.167

By that time, the relationship was not only a source of embarrassment for the United States, but of aggravation for the island.168

Scholars and commentators have long been divided over what to make of Public Law 600, and in particular the fact that it describes itself as being “in the nature of a compact.”169 Many point to this phrase as evidence that the United States and Puerto Rico entered into the agreement as something like separate sovereigns, and that Puerto Rico’s colonial status has been rescinded.170

Perhaps the best evidence in favor of this view is the representation that the United States itself made to the United Nations at the time. Article 73 of the United Nations Charter requires nations to make regular reports about their non-self- governing areas (i.e., colonies). Following the passage of Public Law 600, however, the United States told the United Nations that such reports would no longer be necessary, since the island was now sovereign.171 The United States noted that Public Law 600 “expressly recognized the principle of government by consent,” and was “adopted in the nature of a compact.”172 The U.N. accepted the representation.

Others argue, often to their own dismay, that Public Law 600 is nothing more than a statute—one that Congress could repeal without Puerto Rico’s consent.173 One possible implication is that Congress could not give away its power even if it wanted to, short of granting the island independence, statehood, or otherwise moving it into a different constitutional category.

In part because Public Law 600 does not provide clear answers, other attempts have been made to move Puerto Rico from commonwealth status to something more constitutionally recognizable—independence and statehood being the two most obvious options. Independence has never commanded majority support, but statehood parties have often dominated political office on the island.174

A threshold objection must be addressed, before getting to what the implicit terms of the compact may be. It might be argued that the terms of this compact have indeed been specified for all cases in which there is no explicit term, and that the specification is that Congress gets to decide on all such matters.

We are willing to concede that Congress bargained for what one might call the residual right of control. Parties often bargain to grant one side discretion in decision making.175 That, for example, is the very essence of most employer- employee relationships: the employer has bargained to be able to tell the employee what tasks to do. But this is still a bargain; one that is supposed to benefit both sides. And implicit in the bargain is that one side will not use its authority to act in ways that expropriate from or unilaterally harm the other.176

Put differently, what we describe is the distinction between one side being the property of the other and there being a contract between the two. We use this distinction intentionally because when the question of Puerto Rico’s relationship with the rest of the United States came up in the early 1900s, the Supreme Court ruled that constitutional rights did not necessarily extend to Puerto Rico, even though it was part of the U.S. And the reason for creating an exception for the rights granted by the Constitution was that Puerto Rico was different from the states; it was not a voluntary entrant into the Union, but rather was the property of the rest of the United States.  In 1952, though, as part of the new world order where colonies

and imperial subjugation were supposed to be things of the past, the U.S represented to the rest of the world (and to Puerto Rico) that the relationship was changing. Now, Puerto Rico was going to be part of the compact, with full rights of self governance; the days of colonial oppression were supposedly over.

Assuming that what we have is indeed a compact that is silent on the question of expulsion, what are the implicit terms that international law or practice provide? As explored elsewhere, the question of expulsion is latent in international law, and the rules, such as they are, must be found by integrating the traditional rules of state sovereignty (which gave nations total control over their borders, including the power to cede territory without the approval of its residents) and the modern principle of self-determination (which would give ultimate control to the territory’s residents instead).177

III.  Constitutional Principles of Statehood and Expulsion

When in the course of human events, it becomes necessary for one people to dissolve the political bonds which have connected them with another . . .178

The US Constitution was forged in the wake of a secession, and, decades later, secession was its greatest test. The Revolutionary War resulted in an involuntary transfer of sovereign territory away from England; the Civil War was an attempt to do the same to the United States themselves. In both cases, the force for change came from the periphery, and was opposed from the center.

But what if it were otherwise? What if England had decided to quit its fractious and expensive American colonies, against the colonists’ wishes? Practically speaking, the outcome surely would have been similar—American “independence”—though the process would have differed, and likely would not have involved war. (It is hard to imagine the colonists taking up arms and sailing to England to force the crown to keep them.)

Or consider the situation if Lincoln had not been elected in 1860. If, say, the Democratic Party had not been so riven by disagreement about slavery, and Stephen Douglas had won its undivided loyalty, the doctrine of “popular sovereignty” might have become the official government position. And although Douglas himself opposed secession in 1861, the logic of popular sovereignty might seem to support it. If the people are sovereign, why should they be ruled by borders? What if the North had decided that it was better to expel the South—or at least let it go—rather than to sacrifice more than half a million lives to keep it?

177 See Blocher, Gulati, & Helfer, supra note 36.

178 THE DECLARATION OF INDEPENDENCE para. 1 (U.S.  1776).

Evaluating the legality of expulsion, or of any changes to sovereign territory, tests the very boundaries of law itself. One might well believe that the issue is important, and yet deny that the constitution has anything to say about it—politics alone will likely be the final tribunal.

This is especially true of Puerto Rico and the other territories of the United States. Consider the following from Felix Frankurter, then a clerk in the Bureau of Insular Affairs at the War Department:

The form of the relationships between the United States and the unincorporated territory is solely a problem of statesmanship.

History suggests a great diversity of relationships between a central government and dependent territory. The present day shows a great variety in actual operation. One of the great demands upon inventive statesmanship is to help evolve new kinds of relationship so as to combine the advantages of local self-government with those of a confederated union. Luckily, our Constitution has left this field of invention open.179

We agree that politics would play a leading role in any attempted expulsion. Courts would be unlikely to resolve the issue, just as they were not the main players in the debate over the constitutionality of the South’s attempt to secede. If asked to decide the constitutionality of an expulsion, whether of a state or a territory, the Court might well invoke the political question doctrine and stay on the sidelines.

But the broad reach of politics and limited role of courts does not mean that the questions are not constitutional. In Luther v. Borden—the case that effectively established the political question doctrine—the Court did not hold that the “republican form of government” clause of Article Four is a nullity, but rather that it must be enforced by the President and Congress.180 It has said roughly the same thing about sovereign authority over the territories.181 And in some ways, the Court has weighed in on the legality of secession. In the post-war case of Texas v. White, for example, the Court held that Texas had never left the United States, that the Constitution did not permit secession, and that the ordinances of secession and all legislative acts based on them were “absolutely null.”182

179 Monge, supra note 86, at 235 (quoting Mora v. Torres, 113 F. Supp. 309 (D.P.R. 1953) (quoting Frankfurter)) (emphasis added); see also Sanchez-Valle, 136 S. Ct. at 1875 (describing Puerto Rico’s attainment of commonwealth status as a “prime example” of Congress’s “broad latitude to develop inventive approaches to territorial governance”).

United States, 137 U.S. 202, 212 (1890) (“Who is the sovereign, de jure or de facto, of a territory, is not a judicial, but a political, question, the determination of which by the legislative and executive departments of any government conclusively binds the judges, as well as all other officers, citizens, and subjects of that government. This principle has always been upheld by this court, and has been affirmed under a great variety of circumstances.”).

182 Texas v. White, 74 U.S. 700, 701 (1868), overturned in part by Morgan v. United States, 113 U.S. 476 (1885)

Consider, likewise, the Supreme Court of Canada’s opinion on the legality of Quebec’s attempted secession.183 The Court rejected the notion that Quebec had a right to unilateral secession under Canadian law, but also identified circumstances under which such secessions would be legally permissible.184 Crucially for our purposes, it did so as a legal matter, and in a way that the parties ultimately respected.

In short, we think that the Constitution can speak to the legality of expulsion, and that its rules matter. Whether or not litigated, the very idea of the constitution is hugely important.185 Unfortunately, the constitutional rules are not entirely clear and, to the extent that they are, leave something to be desired.

Undoubtedly there are constitutional prohibitions on particular types, methods, or motivations for expulsion. Expulsion motivated by racial animus and inflicting harm on Puerto Ricans would presumably be forbidden by the Equal Protection clause, to take one obvious example. Such claims could be evaluated by familiar doctrines, and subject to analysis like any other government action.

It must be emphasized, of course, that the text of the Constitution gives Congress enormous power in this area. Article V, Section 3 says that “New States may be admitted by the Congress into this Union.”186 The only limits that section mentions (forbidding the creation of states within existing states, or by “Junction of two or more States,” without the consent of the states concerned) are irrelevant to the admission of Puerto Rico. Moreover, the same provisions give Congress “Power to dispose of and make all needful Rules and Regulations respecting the Territory or other Property belonging to the United States”—this is the Territories Clause, and has been read (in the Insular Cases and elsewhere) to give Congress basically plenary authority over the territories.

These provisions seriously complicate any constitutional claims Puerto Rico might make for statehood. The matter is not clearly in the island’s favor. But it is not clearly a loser, either.

186 U.S. Const., Art IV, sec. 3.

There is precedent for statehood-on-demand—precedent that supporters of Puerto Rican statehood have invoked.187 In 1796, Tennessee became the 16th state— and the first to be carved out of federally owned territory. (The thirteen colonies, Kentucky, and Vermont preceded it, but none was ever a territory). But the path to statehood was not simple. The land that today constitutes Tennessee was originally granted to the federal government by North Carolina,188 to be governed under the terms of the Northwest Ordinance.189 As to statehood, Article V of the Ordinance stipulated that “[t]here shall be formed in the said territory not less than three nor more than five states.”190 And, upon reaching “sixty thousand free inhabitants therein, such State shall be admitted, by its delegates, into the Congress of the United States, on an equal footing with the original States, in all respects whatever.”191 However, admission of States with a population of less than sixty thousand would be allowed if “consistent with the general interest of the confederacy.”192

Congress acquiesced to the conditions of North Carolina’s legislature, and in 1790 passed a bill establishing the Southwest Territory.193 The Territory elected its first legislature in 1794,194 and, within the year, the legislature passed a bill providing for a census and polling regarding public opinion of Statehood.195 The census indicated that the Territory had a population of 77,262 persons,196 and the results of the referendum showed “6,504 votes in favor of Statehood. . . and 2,562 against.”197

The census and referendum results prompted Governor Blount to call for a convention to adopt a state constitution.198 And, in February 1796, the convention adopted a constitution proclaiming that the people of the Territory “mutually agreed with each other to form themselves into a free and independent State by the name of the State of Tennessee,” and asserted they “ha[d] the right of admission into the General Government [of the United States] as a member state thereof.”199 Following adoption of their constitution, Tennessee elected a new Governor and

replaced its territorial assembly with a newly elected state legislature.200 Stanley Folmsbee writes that following the adoption of Tennessee’s constitution “government under the law creating the Southwest Territory came rapidly to an end.”201

In April, President Washington presented Tennessee’s constitution, the results of the territorial census, and Tennessee’s request for admission to Congress.202 Opponents of immediate admission argued that the terms of the Act of 1790 indicated an antecedent act of Congress was required to establish the borders of States.203 Furthermore, the Act did not authorize the territorial government to undertake a census,204 and the census conducted by the territorial government overinflated the number of inhabitants.205

Proponents of immediate admission argued that opponents of immediate admission were “spinning a finer thread than was necessary.”206 Rather than ask whether Tennessee had met all of the conditions required by the Act of 1790, the only appropriate question was whether Tennessee should be admitted as a State.207 Proponents argued in favor of the principle of self-determination—the people of the Southwest Territory desired to be admitted to the Union as a State, and unless admission worked to the general detriment of the Union, Congress should admit Tennessee as a State.208  Furthermore, the people of the Southwest Territory “were at present in a degraded situation; they were deprived of a right essential to freedom—the right to be represented in Congress.”209 Should Congress admit Tennessee to the Union, prior to having the requisite number of inhabitants, “it was only a fugitive consideration.”210 Rather, “where there was doubt, Congress ought to lean towards a decision which should give equal rights to every part of the American people.”211

After two days of debate,212 the House passed a resolution recognizing that the “Territory, now bearing the name of the State of Tennessee was entitled to all privileges enjoyed by the other States of the Union, and that it should be one of the sixteen States of America.”213  In the Senate, political concerns predominated.

President Washington had made public his decision to not run for a third term, and Federalists—who controlled the Senate—were worried that admission of Tennessee to the Union would tip the Presidential election in favor of Republican candidate Thomas Jefferson.214 (It is not hard to see the modern analogue if Puerto Rico were to actively seek statehood.) To that end, the Senate adopted a bill providing for the Territory to be admitted as a single State, but only following “a more satisfactory census had been taken under the authority of Congress.”215

The House refused to accept the terms of the Senate bill, but instead proposed a compromise whereby Tennessee would be immediately admitted to the Union, but would have only one Representative in the House—and consequentially only three electoral votes—until the next federal census in 1800.216 The Senate accepted the compromise, and President Washington signed a bill admitting Tennessee into the Union on June 1, 1796.217

If Puerto Rico were to attempt a similar move, it would not necessarily be simple brinksmanship, but potentially a claim of right. Its long colonial history makes Puerto Rico different from, say, Nova Scotia (which has also made noise about joining the U.S. 218). As Rogers Smith puts it:

  • he governing authority asserted by the United States over Puerto Rico is and always has been substantially illegitimate, in violation of the U.S. Constitution and the nation’s broader political

Where that leaves the issue of Puerto Rican nationality is in important respects unclear, but it does clearly mean that the United States is not entitled to decide the status of Puerto Rico, at least not any further than Puerto Ricans wish them to do. Puerto Ricans should be seen as legally entitled to decide their status for themselves (a power that is arguably at the heart of national identity).219

What this would mean if Puerto Ricans chose statehood is that Congress would be constitutionally required to go through the constitutionally-prescribed processes for admission of new states, as discussed above.220 There are at least three reasons why this might be true.

First, one might reject the notion of “unincorporated territories” entirely, and say that the only constitutional way in which the United States can acquire new territory is with a promise of statehood (Hawaii and Alaska being the two most recent examples), independence (Philippines), or incorporation (Northern Marianas). Chief Justice Fuller suggested as much in the Insular Cases, rejecting the

notion that Puerto Rico could be indefinitely treated like a “disembodied shade.”221 One can see the same basic theme in political comments at the time.222 Even the Northwest Ordinance of 1787 contemplated that the acquired territory would eventually be carved into states.223

The passage of time alone is not enough to disregard the importance of this promise. After all, Alaska was purchased from Russia in 1867 (apparently with no promise of statehood),224 was made a territory in 1912, and eventually achieved statehood in 1959. Sparrow notes that “the period between the first petition or bill for statehood and admission as a state … lasted an average of more than thirteen years, … for seven states, the process took longer than twenty years.”225 But even Dred Scott was not so racist or cavalier as to support permanent territorial limbo: “There is certainly no power given by the Constitution to the Federal government to establish or maintain colonies bordering on the United States or at a distance, to be ruled and governed at its own pleasure; …. [N]o power is given to acquire a territory to be held and governed permanently in that character.”226

Gary Lawson and Guy Seidman have pursued a similar line, arguing, as a matter of enumerated powers, that the only constitutional basis for the federal government’s acquisition of sovereign territory is as an incident of Congress’s power to grant statehood.227 Applying this theory, Lawson and Seidman have no specific objections to the acquisition of Puerto Rico;228 while their “instinct” is that the acquisition of Philippines was unconstitutional because there was never a reasonable prospect of statehood.229 Further, they insist that “the constitutionally relevant moment is the moment of acquisition. Once the acquisition has been constitutionally validated, …. There is nothing in the Territories Clause that requires Congress either to admit a territory as a state or to dispose of it (perhaps by granting independence) if statehood ever ceases to be an option.”230

We believe that the proper inquiry must take into account more than the moment and mechanism of acquisition. Indeed, a second theory as to why Puerto Rico can demand statehood now is that Congress has already promised as much and is bound by that promise, even if it would not have otherwise been so obligated.

Precisely when that promise was made is debatable, but there are three candidates. Those who reject the notion of “unincorporated territories” might say that the promise was made at the moment of acquisition in 1898, as noted above. Others might argue, as a former governor of Puerto Rico did, that an “implied pledge of statehood [was] made to Puerto Ricans when citizenship was granted.”231 A third, and we think the strongest, possibility is that Public Law 600 and the approval of Puerto Rico’s constitution in the 1950s not only promised but actually (or at least partially) delivered a form of statehood.232

Additionally,—at least since the 1970s—American presidents have regularly expressed support for Puerto Rican statehood. Gerald Ford was apparently the first to do so, albeit in the waning days of his presidency, leading president-elect Jimmy Carter to respond, “I would be perfectly willing to see Puerto Rico become a state if the people who live there prefer that.”233 President George Bush reiterated support for statehood in his inaugural speech,234 and Barack Obama said much the same thing a few years later.235 Most recently, Donald Trump said, “There are 3.7 million American citizens living in Puerto Rico. As citizens, they should be entitled to determine for themselves their political status.”236

Third, even if one does not believe that the federal government is constitutionally bound to make good on its promises, Puerto Rican statehood (or independence) might be required as a remedy for the longstanding wrong of its unconstitutional status.

It is hard to ignore the degree to which race and racism played a role in shaping Puerto Rico’s political status—to a degree that raises questions for Equal Protection.237 It is blackletter constitutional law that racial animus, combined with

232 United States v. Quinones, 758 F.2d 40, 42 (1st Cir. 1985) (“Thus, in 1952, Puerto Rico ceased being a territory of the United States . . . “); Mora v. Mejias, 206 F.2d 377, 387 (1st Cir. 1953)(“Puerto Rico has thus not become a State in the federal Union like the 48 States, but it would seem to have become a State within a common and accepted meaning of the word.”).231 CABRANES, supra note 168, at n. 19 (quoting Address by Governor Carlos Romero Barcelo, before Los Angeles World Affairs Council).

237 It is also worth noting, as Cabranes suggests, that matters were even worse vis-à-vis the Philippines, which helps explain why Puerto Rico was kept as a territory. With regard to the Philippines, ties with which would soon be severed, “[e]xpressions of concern about the annexation of Oriental peoples were commonplace,” while “[t]he relatively tender treatment accorded to the Puerto Ricans may be partially explained by the representations made in Congress concerning the racial composition of the island.” CABRANES, supra note 168, at 30-31.

disparate impact, can prove a violation of the Equal Protection clause.238 This is especially true when voting and other rights of political participation are in play. Put differently, the history of the denial of the right of representation in national governance to Puerto Ricans is largely a story of racism and imperialism. The denial of those rights to Puerto Ricans should be constitutionally suspect; requiring strong evidence that the denial of rights was not motivated by racial animus. Best we can tell, there is no such evidence—other than perhaps the claim that at some points in time the inhabitants of Puerto Rico have not wanted national representation because they were receiving tax benefits or were seeking to maintain their culture of difference from the mainland.239

But the very conceptualization of national representation as something that could be traded away for tax breaks by one subset of citizens who are largely of a different (and disadvantaged) race than the majority is itself problematic. As a constitutional matter, voting is supposed to be sacrosanct. It is generally thought to be both an individual right (that is, the collective cannot trade it away in exchange for some benefits that the local government sees) and an inalienable one (no trading of the right, especially for financial reasons).240 Yet, for marginal regions like Puerto Rico and American Samoa, courts and policy makers seem comfortable treating the right to vote as being at the mercy of the local collective.

B.   Expelling States?

Our focus here is on the legality of expelling territories—and specifically Puerto Rico—not states. And to the extent that expulsion has even been contemplated, a firm line has typically been drawn between expulsion of territories and of states. For example, Bartholomew Sparrow notes that in a brief in Crossman

  1. United States (1901), U.S. Solicitor General John Richards argued that “[t]he only indissoluble, inseparable parts of the United States” were “the States of the Union, the governing body.” He did not believe there to be any power to “disintegrate the Union” but did “believe there is power to dispose of territory which simply belongs to the United States.”241

But it is not clear that the inquiry can stop there. Is statehood a safe harbor from the kind of expulsion Ponsa describes? To consider the possibility of expelling either states or territories, one has to start with questions about the nature of the union itself—questions that are thought to have been settled at Appomattox. And

This cultural preservation argument has apparently received consideration from the D.C. Circuit.  See Tuaua v. United States, 788 F.3d 300, 310-11 (D.C. Cir. 2015).  240 See, e.g., Richard L. Hasen, Vote Buying, 88 CAL. L. REV. 1323, 1324 (2000) (describing the general illegality and opprobrium attached to vote buying in the United States).

241 Quoted in SPARROW, supra note 15, at 23.

we are loath to suggest disagreement with Abraham Lincoln about the permanence of the union.242

Still, one might ask: What if the union had blessed, or demanded, the South’s exit? Would that be an attempted secession (of a majority, perhaps), and be analyzed the same way? If Southern states had refused the demands of Reconstruction, would there have come a point at which unrepentant and widespread embrace of slavery would be so inconsistent with the national law and ethos that it could justify expulsion?243 Would resumption of war have been the only alternative, and is that preferable?

Because there is no explicit power to expel or deannex a state, any such power would have to be found by implication in other constitutional powers. And although state and national borders are often taken for granted today, the location of those borders—and the concomitant power to shape them—were central to the Declaration of Independence, the substance of the Constitution, and the early development of the nation.244 The Articles of Confederation’s inability to resolve border disputes between states was one of its central defects.245 But precisely because of those ongoing disputes and uncertainty, “[t]he Framers could … go no further than defining the basic components for future mapmakers to assemble over time.”246

In doing so, they eliminated the Articles’ provision regarding Canada’s accession to the Union,247 arguably leaving the Constitution without a specific

If I could save the Union without freeing any slave I would do it, and if I could save it by freeing all the slaves I would do it; and if I could save it by freeing some and leaving others alone I would also do that.”).

REV. 39 (1952) (discussing the reasoning and historical context behind Article XI in the Articles of Confederation and the founders’ initial concern with Canada).

mechanism by which the nation could acquire more sovereign territory.248 This became particularly pressing when Jefferson was presented with the prospect of the Louisiana Purchase. As Jefferson noted, “The Constitution … has made no provision for our holding foreign territory, still less for our incorporating foreign nations into our Union. The executive in seizing the fugitive occurrence which so much advances the good of the country have done an act beyond the Constitution.”249 (Notably, the debate over the constitutionality of the purchase was not nearly so public as that over the status of Puerto Rico.250)

The legality of the Louisiana Purchase is accepted now,251 but the debate over the constitutionality of annexation has implications for the future of constitutional authority over the nation’s borders.252 If the power to annex can be inferred from the Constitution, what about the power to de-annex or expel?

To the degree that control over borders is implied in the nature of sovereignty, this argument has a lot to recommend it. In the debate over the Louisiana Purchase, Representative Joseph Nicholson argued, echoing Justice White’s logic in the Insular Cases, that “the right must exist somewhere. It is essential to independent sovereignty.” Representative Randolph similarly noted that, “If the old Confederation—a mere government of States—a loosely connected league . . . could rightfully acquire territory in their allied capacity, much more is the existing Government competent to make such an acquisition.”253 As a matter of political practice and international law, cession of territory has long been regarded as part of sovereign authority.

In the 1890’s Jones v. United States (a case involving the status of the guano islands), the Supreme Court said as much, while invoking its own case law, first principles, and international law:

248 See, e.g., SPARROW, supra note 15, at 1 (“[T]he U.S. Constitution has almost nothing on the territorial expansion of the United States.”); John Gorham Palfrey, The Growth of the Idea of Annexation, and Its Breaking Upon Constitutional Law, 13 HARV. L. REV. 371, 373 (1900) (arguing that it is not likely that the later Constitution was meant to be less expansive than the Articles in this regard).

249 Palfrey, supra note 248, at 379.

250 Brook Thomas, A Constitution Led by the Flag, in RECONSIDERING, supra note 8, at 91 (“The constitutional debate concerning the Louisiana Purchase took place exclusively in private correspondence and within the conscience  of Jefferson himself; the debate surrounding the Insular Cases was very public.”).

251 See John Hanna, Equal Footing in the Admission of States, 3 BAYLOR L. REV. 519, 528 (1951) (“If there were doubts as to the power of the United States to acquire [lands], these have been resolved decisively in favor of the Federal government, not only by the Supreme Court but by the people through their elected representatives in the Congress and the presidency.”).

252 Although the constitutionality of the Purchase is relatively well-settled, territorial annexation nonetheless raises important constitutional questions, which may have implications for broader matters of constitutional law. Along those lines, see Daniel Rice, Territorial Annexation as a “Great Power”, 64 DUKE L.J. 717 (2015) (arguing that “the annexation of foreign territory is exactly the sort of power that is too important to be left to implication through the Necessary and Proper Clause”).

253 LAWSON & SEIDMAN, supra note 227, at 23 (collecting these and other statements, but concluding that they “are not valid arguments in the context of the federal Constitution”).

By the law of nations, recognized by all civiliezed [sic] states, dominion of new territory may be acquired by discovery and occupation as well as by cession or conquest; …. This principle affords ample warrant for the legislation of congress concerning guano islands.254

For those with a more limited view of federal power—or who are determined to ground it in specific text—there is an argument that de-annexing a state, or ceding it to another country, would be beyond the enumerated powers of Congress. Lawson and Seidman, for example, argue that there is no explicit power of territorial acquisition, and so any federal acquisition of territory can only be “as a means of carrying into effect other national powers, such as the power to admit new states or to provide and maintain a navy.”255

Finding an authorization for expulsion is only part of the story, however.

Federal powers are subject to independent restrictions. If the United States were to attempt to expel a state, a range of constitutional prohibitions would be implicated. The first clause of Article IV, Section 3 provides: “New states may be admitted by the Congress into this union; but no new states shall be formed or erected within the jurisdiction of any other state; nor any state be formed by the junction of two or more states, or parts of states, without the consent of the legislatures of the states concerned as well as of the Congress.”256 The Constitution forbids the alteration of a state’s borders without its consent, and changing federal borders so as to exclude a state might be considered a “change” of the state’s borders as well.

Further, could Congress’s Fourteenth Amendment enforcement power override the supposed sanctity of state borders—if, for example, expelling a state were necessary to guarantee Equal Protection to those threatened by an oppressive state government?257 Likewise, what of the federal government’s textually mandated obligation to guarantee a republican form of government in the states?258

Our intention is not to argue whether expulsion of an American state would or would not be constitutional, and it is unlikely that the question would be answered in court. But there is still a “constitutional” question worth asking.

IV.  Law and Expulsion

The case of Puerto Rico illustrates a broader legal question: How can domestic and international law provide for unwinding of sovereignty? Historically, nations have sought to expand, or to maintain their size by preventing secessions,
255 LAWSON & SEIDMAN, supra note 227, at 5.254 Jones v. United States, 137 U.S. 202, 212 (1890).

256 U.S. CONST. art. IV, § 3.

257 U.S. CONST. amend XIV § 5.

258 U.S. CONST. art. IV, § 4 (providing in relevant part that “[t]he United States shall guarantee to every State in this Union a Republican Form of Government”).

and so the background principles of international and constitutional law are designed to respond to those outward pressures. The rights of former colonies and their peoples to accession, however, are generally ignored. The U.S. constitution provides explicitly for the creation of new states, for example, but not the dissolution of existing ones; it has been interpreted to permit the acquisition of territory, but says nothing about how it can be disposed of.

The same is true outside of the United States. Foundational principles of international law are predicated on the notion that nations will seek to gain, preserve, and defend territory. This is sensible, since the history of the world has largely been a history of the expansionist impulse. The colonial powers, after all, profited handsomely by denuding their colonies of resources.

Today, the scales have tipped in the opposite direction. Tens of millions of people—one-sixth of the Caribbean’s population, for example—still live in colonies directly controlled by a distant metropole.259 But these colonies now often represent an economic burden, not a boon, for the nations that hold them, and in no existing colony is there clear support for secession. If a push for “independence” arises, then, it is more likely to come from the center than from the edges. Law, we argue, may give the colonies—including Puerto Rico—tools with which to resist.


259 OOSTINDIE & KLINKERS, supra note 12, at 220 (“Of the total population of the Caribbean, an estimated 37 million people, almost fifteen per cent live in areas which still maintain constitutional ties with the mother country.”).
