Equal Protection Does Not Mean Equal SSI 
Benefits for Puerto Rico Residents, Says 
Supreme Court 
April 28, 2022 
On April 21, 2022, the U.S. Supreme Court decide
d United States v. Vaello-Madero, a case asking 
whether the equal protection guarantee in the U.S. Constitution’s Fifth Amendment requires Congress to 
provide the same federal benefits (specifically
, Supplemental Security Income [SSI] benefits for the aged, 
blind, and disabled) to Puerto Rico residents as to residents of the 50 states. In a ruling that reaffirmed 
Congress’s constitutional authority to treat territorial residents differently as long as it has a rational basis 
for doing so, the Supreme Court determined that the Fifth Amendment does 
not require Congress to 
extend SSI benefits to Puerto Rico residents. The Supreme Court’s decision reversed the determinations 
of both lower courts. This Sidebar discusses the legal arguments advanced before the Supreme Court 
before analyzing considerations for Congress. 
Background 
Facts of the Case 
While living in New York, José Luis Vaello-Madero became eligible for, and began receiving, SSI 
disability benefits. He later moved to Puerto Rico, where he continued to receive SSI payments. By law, a 
perso
n must be a resident of the United States to be eligible for SSI benefits. For purposes of the relevant 
statute, Congres
s defined “United States” to mean the 50 states and the District of Columbia. Congress 
extended SSI eligibility to residents of the Northern Mariana Islands in 1976 but has not done so for 
Puerto Rico or other U.S. territories. Accordingly, the Social Security Administrati
on sued Vaello-Madero 
to recover the payments he received while living in Puerto Rico. In response, Vaello-Madero argued that 
excluding Puerto Rico residents from SSI eligibility was unconstitutional—specifically, that it violated his 
constitutional right to equal protection under the law.

Constitutional Provisions 
Under t
he Territory Clause in Article IV of the U.S. Constitution, Congress is empowered to “make all 
needful Rules and Regulations respecting the Territory . . . belonging to the United States,” a phrase 
interpreted to give Congres
s broad authority over nonstate entities such as Puerto Rico. Like all of its 
legislative powers, however, Congress’s territorial authority is bound by the other provisions of the 
Constitution, including the Fifth Amendment. 
The Constitution’s Fifth Amendment does not contain the words “equal protection,” but the Supreme 
Court has
 held that the Fifth Amendment’
s Due Process Clause imposes on the federal government the 
equal protection obligations that states have under the Fourteenth Amendment’
s Equal Protection Clause. 
Equal protection, the Court has said, “is essentially a direction that all persons similarly situat
ed should be 
treated alike,” unless the government is entitled to treat them differently. Statutes that create certain 
classifications—differentiating between people based on characteristics lik
e race or
 sex—or that burden 
fundamental rights must meet higher levels of scrutiny to survive constitutional challenges. Statutory 
classifications that do not receive heightened scrutiny are generally valid if they have a 
“rational basis,” 
meaning that a court will generally uphold the challenged legislation if it is reasonably related to a 
legitimate government purpose. 
Case Law 
Two previous Supreme Court cases applied the rational-basis standard of review to evaluate challenges to 
legislation that treated Puerto Rico differently from the 50 state
s. Califano v. Torres (1978) involved a 
claim that the SSI program unconstitutionally burdened the fundamental right to travel because it 
disadvantaged people who moved from the mainland to Puerto Rico. The 
Torres court
 footnoted in its 
summary reversal that at least three rationales were offered to justify Puerto Rico’s exclusion from the 
SSI program, implying that they were “rational and not invidious”: 
1.  Puerto Rico’s “unique tax status”; 
2.  the “extremely great” cost of including Puerto Rico in the SSI program; and 
3.  the risk that the SSI program “might seriously disrupt” Puerto Rico’s economy. 
Although 
Torres appeared to subject the SSI program’s validity to rational-basis review, it did not 
squarely address an equal protection challenge.  
Unlike 
Torres,
 Harris v. Rosario (1980) involved a Fifth Amendment equal protection challenge similar to 
that raised in 
Vaello-Madero. In 
Rosario, recipients of a different federal benefit program argued that 
lower reimbursement levels in Puerto Rico relative to the 50 states violated the Fifth Amendment’s equal 
protection guarantee. Applying the rational-basis standard, the 
Rosario court
 recited the same three 
rationales identified in 
Torres, accepting them as sufficient to justify different treatment for Puerto Rico 
residents for that program. 
Case History 
The U.S. District Court for the District of Puerto Rico first heard Vaello-Madero’s equal protection 
challenge to the SSI program. In 2019, that court found that excluding Puerto Rico residents failed the 
rational-basis test
, holding that classifying a group of the country’s “medically neediest” citizens as 
“second tier” because they live in Puerto Rico “is by no means rational.” The United States appealed that 
decision to the U.S. Court of Appeals for the First Circuit.  
The First Circuit
 agreed that the rational-basis test should apply. However, because the 
Torres court did 
not base its decision on equal protection grounds, and the 
Rosario court did not consider the SSI program, 
  
Congressional Research Service 
3 
those decisions, in the First Circuit’s view
, did not control the outcome of Vaello-Madero’s case. The First 
Circuit
 explained that both 
Torres and 
Rosario were summary dispositions, decided without the benefit of 
briefing or oral argument in the Supreme Court, and thus had less precedential value. Thus, rather than 
treating those cases as determinative, the First Circuit performed its own assessment of the rational basis 
for the U.S. government’s exclusion of Puerto Rico residents from the SSI program.  
The government’s proffered rationales before the First Circuit aligned with the first two noted in 
Torres (the United States
 declined to rely on 
Torres’s third rationale). First, regarding Puerto Rico’s unique tax 
status, the First Circuit
 pointed out that the Court’s analysis in 
Torres seemed to erroneously believe that 
Puerto Rico did not contribute to the federal treasury when in fact, as an entity, it does so in amounts 
higher than several other states. Although many 
individual Puerto Rico residents do not pay federal 
income taxes, the SSI program’s income limitatio
ns mean that most qualified recipients in the 50 states 
also do not pay federal income taxes. Second, regarding the cost to include Puerto Rico in the SSI 
program, the First Circuit
 posited that cost-savings alone cannot justify exclusion of one group over 
another similarly situated group; Congress must still have a separate rational basis for choosing which 
group to exclude. Ultimately, the First Circuit
 concluded it could find “no set of facts … establishing a 
rational basis for the exclusion of Puerto Rico residents from SSI coverage.” 
The U.S. Supreme Court Decision in Vaello-Madero 
Majority Opinion 
The U.S. Supreme Court
 reversed the First Circuit’s decision in an 8-1 opinion written by Justice Brett 
Kavanaugh. 
Torres and
 Rosario, wrote the Court, “dictate the result here.” The rational-basis test applies, 
and Puerto Rico’s tax status, in the Court’s view, supplies a rational basis for disparate treatment. To 
decide otherwise, the Court
 cautioned, could mean that all federal benefits must be extended to Puerto 
Rico, which in turn could mean that federal 
taxes should also be applied to Puerto Rico on the same basis 
as the 50 states. The Court addressed no other rationale for Puerto Rico’s exclusion from the SSI 
program. The Court
 specified, however, that its decision “should not be read to imply that Congress may 
exclude residents of individual States from benefits programs.”   
Concurrences 
Justice Clarence Thomas wrote a separate concurrence declaring that he i
s no longer convinced that the 
Fifth Amendment supports an equal protection doctrine coextensive with the Fourteenth Amendment’s 
protections. Based on his review of the Court’s Fifth Amendment jurisprudence, he contended that there 
was “limited support” for an equal protection guarantee. Though cautioning that his “conclusions remain 
tentative,” Justice Thomas
 advanced a theory that the Fourteenth Amendment’
s Citizenship Clause may 
be an alternative source for a prohibition on racial discrimination by the federal government, “at least 
with respect to civil rights.” 
Justice Neil Gorsuch also wrote a separate concurrence calling for the Court to overrule a line of cases 
known as t
he Insular Cases. The 
Insular Cases developed a
 judicial distinction between “incorporated” 
territories, where the U.S. Constitution applies in full, and “unincorporated” territories, where only 
“fundamental” provisions apply. That distinction, Justice Gors
uch opined, may have had support “in 
academic work of the period, ugly racial stereotypes, and the theories of social Darwinists,” but not in the 
Constitution’s language “or its original understanding.” Because both parties in 
Vaello-Madero acceded 
that the Fifth Amendment’s equal protection guarantee was “fundamental” and applied in Puerto Rico, 
overruling the 
Insular Cases was unnecessary to resolve Vaello-Madero’s case. However, Justice Gorsuch 
  
Congressional Research Service

urged the Court to recognize “that the Insular Cases rest on a rotten foundation” and overrule them in an 
appropriate future case. 
Dissent 
Justice Sonia Sotomayor dissented. In her
 view, “there is no rational basis for Congress to treat needy 
citizens living anywhere in the United States so differently from others.” Justice Sotomayor
 reiterated 
several of the First Circuit’s observations: that 
Torres and 
Rosario were summary dispositions; that those 
cases misstated Puerto Rico’s contributions to the federal treasury; and that SSI recipients generally do 
not pay federal taxes, making it untenable to rely on Puerto Rico residents’ nonpayment of individual 
federal taxes as a rationale for exclusion from the SSI program.
 Justice Sotomayor
 would have found the 
Puerto Rico residents’ exclusion from the SSI program “irrational and antithetical to the very nature of the 
SSI program and the equal protection of citizens guaranteed by the Constitution.”  
Considerations for Congress 
The Supreme Court’s 
Vaello-Madero decision clarifies that 
Torres and 
Rosario are binding precedent, and 
that congressional actions treating Puerto Rico or other territories differently from the 50 states are 
generally subject t
o deferential rational-basis review. Under 
Vaello-Madero, Puerto Rico’s unique tax 
status sufficiently justifies Congress’s decision to provide different levels of federal benefits to Puerto 
Rico residents. Because the Court’s acceptance of Puerto Rico’s tax status as a rational basis for exclusion 
from the SSI program did not rely on the SSI program’s specific features or operations, it appears that this 
tax-status rationale could justify differential treatment for a range of other federal benefit programs. To 
the extent Congress agrees with this outcome, Congress could consider express references to this rationale 
in future federal benefits legislation. 
Congress could decide to alter the specific exclusion 
Vaello-Madero highlighted in the SSI program. 
Puerto Rico’s Resident Commissioner, for example, introduced
 H.R. 537, the Supplemental Security 
Income Equality Act, in the 117th Congress. This bill would amend the Social Security Act to include 
Puerto Rico, the U.S. Virgin Islands, Guam, and American Samoa as part of the “United States” when 
determining SSI eligibility. The bill would also eliminat
e certain limits on other federal programs’ funding 
to the territories.  
To the extent there is legislative interest, Congress could also address differential treatment between U.S. 
territories and the 50 states in other contexts. For example, in the 117th Congress
, H.R. 1825 and S. 3778, 
both titled Territories Medicare Prescription Drug Assistance Equity Act of 2022, would make 
beneficiaries who reside in Puerto Rico and other U.S. territories eligible for certain Medicare subsidies 
for which they are currently ineligible.
