Supreme Court Stays Enforcement of OSHA’s COVID-19 Vaccination and Testing ETS

Client Alert | 1 min read | 01.13.22

On January 13, 2022, the Supreme Court granted applicants’ emergency motion to stay enforcement of the Occupational Health and Safety Administration’s (“OSHA”) COVID-19 Vaccination and Testing Emergency Temporary Standard (“ETS”). In its decision, the Court explained that the plaintiffs were likely to succeed in showing that OSHA lacked the statutory authority to mandate “84 million Americans to either obtain a COVID-19 vaccine or undergo weekly medical testing at their own expense.” The Court reasoned that “[a]lthough COVID-19 is a risk that occurs in many workplaces, it is not an occupational hazard in most” and to permit “OSHA to regulate the hazards of daily life . . . would significantly expand OSHA’s regulatory authority without clear congressional authorization.” While the Court acknowledged that OSHA has authority to regulate occupational risks related to COVID-19 where the virus “poses a special danger because of the particular features of an employee’s job or workplace,” it emphasized that OSHA’s “indiscriminate approach” does not consider what is an occupational hazard versus a general risk. 

Three justices—Breyer, Sotomayor, and Kagan—issued a dissenting opinion, arguing that the mandate “falls within the core of the agency’s mission: to ‘protect employees’ from ‘grave danger’ that comes from ‘new hazards’ or exposure to harmful agents.” Moreover, the dissent opined that even if the merits were a close question, the Court should not have issued a stay here because the balance of harms and the public interest do not support such an action since “[t]he lives and health of the Nation’s workers are at stake” and outweigh any potential economic harm.

The Court also issued its decision regarding the Centers for Medicare & Medicaid Services interim final rule. Unlike with the OSHA ETS, the Court granted the Government’s request to stay two district court decisions enjoining enforcement of the rule.

Eleventh Circuit Hears Argument on False Claims Act Qui Tam Constitutionality

On the morning of December 12, 2025, the Eleventh Circuit heard argument in United States ex rel. Zafirov v. Florida Medical Associates, LLC, et al., No. 24-13581 (11th Cir. 2025). This case concerns the constitutionality of the False Claims Act (FCA) qui tam provisions and a groundbreaking September 2024 opinion in which the United States District Court for the Middle District of Florida held that the FCA’s qui tam provisions were unconstitutional under Article II. See United States ex rel. Zafirov v. Fla. Med. Assocs., LLC, 751 F. Supp. 3d 1293 (M.D. Fla. 2024). That decision, penned by District Judge Kathryn Kimball Mizelle, was the first success story for a legal theory that has been gaining steam ever since Justices Thomas, Barrett, and Kavanaugh indicated they would be willing to consider arguments about the constitutionality of the qui tam provisions in U.S. ex rel. Polansky v. Exec. Health Res., 599 U.S. 419 (2023). In her opinion, Judge Mizelle held (1) qui tam relators are officers of the U.S. who must be appointed under the Appointments Clause; and (2) historical practice treating qui tam and similar relators as less than “officers” for constitutional purposes was not enough to save the qui tam provisions from the fundamental Article II infirmity the court identified. That ruling was appealed and, after full briefing, including by the government and a bevy of amici, the litigants stepped up to the plate this morning for oral argument....
