Supreme Court Blocks Enforcement of the 
CDC’s Eviction Moratorium 
August 30, 2021 
On August 26, 2021, the Supreme Court blocked enforcement of the Centers for Disease Control and 
Prevention’s (CDC’s) nationwide temporary eviction moratorium issued on August 3, 2021. In granting 
the plaintiffs’ emergency motion to vacate a lower court’s ruling allowing the moratorium to remain in 
place pending appeal, the Court determined that the plaintiffs were “virtually certain to succeed on the 
merits of their argument that the CDC has exceeded its authority.” The Court did not reach a decision on 
the merits of the underlying case regarding whether the CDC has the legal authority to impose an eviction 
moratorium, as that case is on appeal before the U.S. Court of Appeals for the District of Columbia 
Circuit (“D.C. Circuit”). 
The CDC originally imposed a nationwide, temporary federal moratorium on residential evictions for 
nonpayment of rent on September 4, 2020, shortly after a narrower set of eviction protections established 
by the CARES Act (§ 4024) expired. The original CDC order had an expiration date of December 31, 
2020. Prior to its expiration, Congress extended the order through January 31, 2021, and the CDC 
administratively extended the order three times: through March 31, June 30, and July 31, 2021. The third 
extension stated that “absent an unexpected change in the trajectory of the pandemic, CDC does not 
expect to extend the Order further.” Citing a surge of cases spurred by the Delta variant, the CDC issued a 
new order on August 3, 2021 implementing another eviction moratorium through October 3, 2021. The 
new order was only applicable in counties with heightened rates of Coronavirus Disease 2019 (COVID-
19) community transmission. The CDC orders were intended to prevent the spread of COVID-19 by 
preventing homelessness and overcrowded housing conditions resulting from eviction.  
The CDC issued the moratoriums pursuant to Section 361 of the Public Health Service Act (PHSA). 
Section 361, which is codified at 42 U.S.C. § 264, authorizes the CDC Director “to make and enforce 
such regulations as in his judgment are necessary to prevent the introduction, transmission, or spread of 
communicable diseases from foreign countries into the States or possessions, or from one State or 
possession into any other State or possession.” Section 361 also includes a non-exhaustive list of 
activities that the CDC can take to exercise this authority, as well as an open-ended category of activities. 
These activities include “the apprehension, detention, or conditional release of individuals,” as well as the 
“inspection, fumigation, disinfection, [and] sanitation [of] . . . sources of dangerous infection to human

beings, and other measures, as in [its] judgment may be necessary.” The CDC’s actions, which followed 
an Executive Order directing it to consider such measures, are unprecedented, both in terms of the breadth 
of the agency’s use of this public health authority and its reach into what is traditionally state and local 
governance of landlord-tenant law. 
As discussed in a previous Legal Sidebar, numerous legal challenges to the initial moratorium were filed, 
resulting in conflicting court rulings by the Sixth, Eleventh, and D.C. Circuit Courts of Appeals. Courts in 
certain jurisdictions that found the initial order unlawful were not enforcing the latest moratorium even 
before the Supreme Court’s August 26, 2021 order.  
In the challenge addressed by the Supreme Court, the D.C. District Court held that the initial moratorium 
exceeded the CDC’s statutory authority, but stayed its order from taking effect pending appeal. In its 
order upholding the stay, the D.C. Circuit stressed that “Congress . . . designated the HHS Secretary the 
expert best positioned to determine the need for such preventative measures, twice stating that it 
authorizes such measures as the Secretary determines ‘in his judgment [are] necessary.’” According to the 
D.C. Circuit, the CDC, acting through delegated authority from HHS, properly used this discretionary 
statutory authority by “carefully target[ing] [the moratorium] to the subset of evictions it determined to be 
necessary to cure the spread of the deadly and quickly spreading Covid-19 pandemic.” Consequently, the 
court concluded that “the CDC’s eviction moratorium falls within the plain text of 42 U.S.C. § 264(a)” 
and that the CDC would be likely to succeed on the merits of its case. 
On June 29, 2021, the Supreme Court denied the plaintiffs’ request to lift the stay, allowing the 
moratorium to remain in force. Justice Kavanaugh’s concurring opinion agreed with the D.C. District 
Court that the CDC “exceeded its existing statutory authority by issuing a nationwide eviction 
moratorium” and that it would need “new legislation . . . to extend the moratorium beyond July 31.” 
Justice Kavanugh however voted to deny the plaintiffs’ application to vacate the stay “because the CDC 
plan[ned] to end the moratorium in only a few weeks . . . and . . . those few weeks will allow for 
additional and more orderly distribution of the congressionally appropriated rental assistance funds.”  
Following the Supreme Court’s June 2021 decision, the President urged Congress to extend the 
moratorium, but Congress did not pass legislation before its expiration. After the order expired, the 
President asked his Administration to review existing statutes to identify legal authority that would 
support a new eviction moratorium. On August 3, 2021, the CDC, citing changed circumstances, issued a 
new order pursuant to the same statutory authority cited in its previous order, PHSA Section 361. The 
CDC stated that the new order was necessary due to the heightened transmissibility of the Delta variant 
that had become the dominant strain of coronavirus in the country since the Supreme Court’s June 2021 
ruling, and narrowed the order’s scope to only those counties with substantial or high transmission rates 
of COVID-19. 
After the CDC issued the new order, the plaintiffs in the D.C. District Court case applied for an 
emergency vacatur of the lower court’s prior decision grating a stay of the moratorium pending appeal, 
arguing that the new order conflicts with the Supreme Court’s ruling. The government countered that, 
according to D.C. Circuit precedent, plaintiffs cannot add the vote of a concurring judge to dissenters to 
create a majority. The government further argued that the plaintiffs had raised a number of arguments for 
vacating the stay in its first application to the Supreme Court, including a decrease in COVID-19 cases at 
the time and changed guidance from the CDC regarding social distancing and mask wearing for the fully 
vaccinated. The dissenting justices did not explain why they dissented and, according to the government, 
they might have agreed with the plaintiffs that, at that time, the CDC’s order was not “necessary” as the 
PHSA required. The government contended that the facts had changed since the Supreme Court’s ruling 
and that COVID-19 cases were again on the rise because of the Delta variant and its ability to be spread 
by fully vaccinated individuals.

Both the district court and the D.C. Circuit denied the plaintiffs’ application to vacate the stay, but the 
Supreme Court granted the application on August 26, 2021, ending enforcement of the nationwide 
moratorium on evictions.  
The Supreme Court’s unsigned per curiam opinion did not resolve the merits of the case. Instead, it 
applied a four-factor test to determine whether a stay on the enforcement of the district court’s decision 
that the order exceeded the CDC’s statutory authority should remain in effect while the case is being 
appealed. The four factors, as articulated in the 2009 Supreme Court decision Nken v. Holder, are:  
(1) the stay applicant has made a strong showing that it is likely to succeed on the merits; (2) the 
applicant will be irreparably injured absent a stay; (3) issuance of a stay would substantially injure 
other interested parties; and (4) the public interest favors or disfavors a stay. 
On the first factor, the Court concluded that the plaintiffs “are virtually certain to succeed on the merits of 
their argument that the CDC has exceeded its authority,” noting that “it is difficult to imagine [the 
plaintiffs] losing.” The Court explained that the explicitly listed activities in PHSA Section 361, including 
fumigation, disinfection, and extermination “of contaminated animals and articles,” “directly relate to 
preventing the interstate spread of disease by identifying, isolating, and destroying the disease itself.” The 
Court viewed an eviction moratorium “markedly different from” the explicitly listed activities because 
“eviction and the interstate spread of disease” is far less directly related to preventing the spread of 
disease. According to the Court, PHSA Section 361 has never been used to justify an action that “has even 
begun to approach the size and scope of the eviction moratorium” and the statute “is a wafer-thin reed on 
which to rest such sweeping power.” The Court also concluded that, under the other three Nken factors, 
“[t]he equities do not justify depriving the applicants of the District Court’s judgment in their favor.” The 
Court noted that the harm to landlords through financial loss and the inability to exercise “one of the most 
fundamental elements of property ownership—the right to exclude” from their property tenants who fail 
to abide by their leases—has increased over time as “many landlords have modest means” and “no 
guarantee of eventual recovery.” The Court held that, in contrast, “the Government’s interests have 
decreased” since the Court’s June 29, 2021 decision, as the government had additional time to distribute 
appropriated rental assistance funds and “Congress was on notice that a further extension would almost 
surely require new legislation.” For these reasons, the Supreme Court granted the plaintiffs’ application to 
vacate the stay. As a result, the CDC’s eviction moratorium will no longer be enforceable (absent an 
intervening court decision to the contrary), thus allowing states and localities to proceed with evictions 
subject to state and local policies. 
Justices Breyer, writing in dissent for himself and Justices Sotomayor and Kagan, would have denied the 
application. Justice Breyer explained that the Court may only vacate a stay when the lower court “clearly 
and demonstrably erred in its application of [the four-factor Nken test],” and noted three reasons why that 
standard had not been met. First, citing the more narrowly targeted new CDC order, heightened concerns 
about the Delta variant, and split decisions by lower courts on the issue, Justice Breyer argued that “it is 
far from ‘demonstrably’ clear that the CDC lacks the power to issue its modified moratorium order.” 
Second, Justice Breyer reasoned that “the balance of the equities strongly favors leaving the stay in 
place.” In the dissent’s view, the plaintiffs have only lost rental income, which has been mitigated by 
rental assistance appropriations from Congress and the CDC order’s requirement that tenants pay “’as 
close to full rent payment’ as possible,” whereas vacating the stay will result in “irreparable harm” 
through increased COVID-19 spread and resulting deaths. Finally, Justice Breyer observed that “the 
public interest is not favored by the spread of disease or a court’s second-guessing of the CDC’s 
judgment.” The dissent concluded that, given the gravity of “the health of millions” at stake, “[the Court] 
should not set aside the CDC’s eviction moratorium in this summary proceeding.”
