In Does v.

Congressional Research Service 26 State and Federal Authority to Mandate COVID-19 Vaccination considering these claims rejected them as unripe—or too early—for review, given that each plaintiff had a pending request for exemption and had not suffered any adverse employment consequence.231 Another claim, raised by an employee union, challenges the manner by which the mandate was implemented. According to the plaintiffs, the vaccination requirement was implemented without undergoing the notice-and-comment rulemaking procedures required by the APA.232 The district court in December 2021 dismissed the case for lack of standing, concluding, among other determinations, that the plaintiff failed to allege that any of its members had suffered an injury-in-fact because it was “speculative as to whether [they] would be disciplined for failure to become vaccinated because, for example, they may choose to become vaccinated or receive an exemption.”233 Following the expiration of the compliance deadline, the White House stated that as of December 8, 2021, the federal government achieved 97.2% compliance with the mandate, with 92.5% of employees having received at least one COVID-19 vaccination dose. For employees who had not yet complied, agencies were undertaking the first step in the enforcement process with education and counseling.234 On December 21, 2021, before agencies began to implement additional enforcement actions, a nonprofit federal employee organization, a federal employee union, and enforcement actions, a nonprofit federal employee organization, a federal employee union, and

court lacked subject matter jurisdiction under the Civil Service Reform Act of 1978 (CSRA) to consider the case.249 The CSRA, according to the court, established “the comprehensive and exclusive procedures for settling work-related controversies between federal civil-service employees and the federal government,” including an “elaborate” remedial scheme that specified the manner by which federal employees may obtain administrative and judicial review of specified adverse employment actions.250 In light of this remedial scheme, the Fifth Circuit rejected plaintiffs’ argument that the CSRA does not apply until the plaintiffs suffer an adverse employment action, agreeing with the government that such an interpretation “would allow federal employees to circumvent the CSRA by filing suit before their employer disciplines or discharges them, thereby ‘gutting the statutory scheme.’”251 Accordingly, the court concluded that the CSRA provided the exclusive avenue for judicial review of the federal employee mandate: once an employing agency finalizes an adverse action, the aggrieved employee may appeal to the Merit Systems Protection Board (MSPB), and an employee who is dissatisfied with the MSPB’s decision is entitled to judicial review in the U.S. Court of Appeals for the Federal Circuit, which has exclusive jurisdiction over such appeals and is “fully capable of providing meaningful review.”252 For these reasons, the Fifth Circuit concluded that the district court lacked subject matter jurisdiction over the plaintiffs’ action and directed the district court to dismiss the case.253 Federal Contractor Mandate

While the scope of~~287 The government’s appeal in Georgia is pending before the Eleventh Circuit.288 Among other issues, the parties’ briefs addressed not only pre-pandemic case law on the Procurement Act, but also the application of the Supreme Court’s decisions in NFIB and Missouri to the federal contractor mandate. According to the government, like the CMS mandate, which was an implementation of the HHS Secretary’s “longstanding practice” of imposing federal health-related requirements under the Medicare and Medicaid statutes, the federal the federal
~~contractor mandate likely applies to fewer workers than the OSHA ETS,278 the mandate, like the~~
~~OSHA ETS, extends across industries. Moreover, while the President has invoked his~~
~~Procurement Act authorities to regulate certain employment practices by federal contractors,~~
~~those instances appear primarily limited to direct regulation of the contractors’ own conduct, as~~
~~opposed to conditions of employment that contractors must set for their employees. Viewed~~
~~through this lens~~contractor mandate reflected a “longstanding practice” by Presidents to use their Procurement Act authority to issue executive orders directed at improving the economy and efficiency of contractors’ operations.289 As examples of prior, similar uses of the Presidents’ Procurement Act authority, the government pointed to the antidiscrimination requirements for contractors, the required use of an electronic employment verification system, as well as a requirement on contractors to provide employees with paid sick leave.290 Thus, according to the government, under Missouri and prior cases in which courts of appeals have applied the lenient standard to afford Presidents “necessary flexibility and broad-ranging authority” in setting procurement policies, the federal contractor , the federal contractor mandate reflects the required nexus to the statutory objective of “an economical and efficient system” for contracting and procurement, given the mandate would, as the President determined, reduce absenteeism and improve efficiency of contractors at sites where they are performing work for the federal government.291 282 Chamber of Commerce v.

Congressional Research Service 32 State and Federal Authority to Mandate COVID-19 Vaccination The state plaintiffs, in contrast, argued that the President’s Procurement Act authority, consistent with the Sixth Circuit’s interpretation, is limited to prescribing the federal government’s own internal procurement policies and does not extend to regulations that would improve the efficiency of federal contractor operations.292 Moreover, the state plaintiffs argued that the federal contractor mandate, like the OSHA ETS, was “a significant encroachment in the lives—and health of a vast number of employees” that “involves billions of dollars of economic activity.”293 Thus, in the state plaintiffs’ view, the Procurement Act, like the OSHA Act, does not provide a clear grant of authority to impose a vaccination requirement.294 The Eleventh Circuit heard oral argument on the government’s appeal on April 8, 2022. The government’s appeals of other preliminary injunctions are pending in the Fifth, Eighth, Eleventh, and Ninth Circuits. ~~mandate could be characterized, like the OSHA ETS, as a~~
~~broad, unprecedented rule that imposes a requirement that has not traditionally been imposed by~~
~~state law or as a matter of custom in many of the covered industries. As the Court noted in NFIB,~~
~~a “lack of historical precedent” on similar prior use of an authority, coupled with a “breadth of~~
~~authority” now claimed, is usually a “telling indication” to the Court that a mandate extends~~
~~beyond the executive’s legitimate reach.279 Thus, while it is unclear whether the Court—if asked~~
~~to review the federal contractor mandate—would construe the President’s Procurement Act~~
~~authorities as narrowly as the Sixth Circuit, the Court’s decisions in NFIB and Missouri tend to~~
~~suggest that it would consider the relevant Procurement Act provisions as not clearly authorizing~~

~~disruptions they create. Viewed through this lens, courts could consider the Head Start mandate to~~
~~be more similar to the CMS IFR at issue in Missouri.299 Like the CMS IFR, the Head Start~~
~~mandate is limited in scope, extending only to a subset of early childhood education providers~~
~~and other entities that promote school readiness; applies in a high exposure setting where multiple~~
~~individuals—many of whom cannot yet be vaccinated—are in close contact and in which~~
~~vaccination requirements are common;300 and is one of numerous federal standards to which~~
~~participating programs are subject, including existing standards on staff health and wellness~~
~~aimed at mitigating the spread of communicable diseases.301 Accordingly, courts could conclude~~
~~that the Head Start mandate falls within the Secretary’s general authorities to issue appropriate~~
~~program performance standards, just as the Court held in Missouri that the CMS IFR falls within~~
~~the Secretary’s general authorities over the regulated health care facilities—including a general~~
~~authority to “administer” Medicare and Medicaid.302~~

Congressional Research Service 34 link to page 42 link to page 42 State and Federal Authority to Mandate COVID-19 Vaccination A few days before the Head Start mandate’s January 31 compliance deadline, four Michigan school districts filed suit to challenge the mandate in Livingston Educational Service Agency v. Becerra.311 In contrast to the Texas and Louisiana courts, the district court presiding over Livingston denied the plaintiffs’ motion for preliminary injunction. The court held that the mandate “plainly falls within the Secretary’s [Section 641A] authority,” including the authority to issue necessary administrative standards to safely carry out day-to-day Head Start program operations; the authority to regulate “the condition and location of facilities” given that COVID-19 spreads through the air via respiratory droplets; and “the broad grant of authority” given to the Secretary to issue appropriate standards to promote school readiness in a learning environment.312 This conclusion, according to the district court, is supported by the Supreme Court’s decisions in NFIB and Missouri. The district court reasoned that the Head Start mandate is more like the CMS mandate affirmed in Missouri because both mandates “are tailored to protect those who work in places with or provide services to at-risk individuals—Medicare and Medicaid patients [in the case of the CMS mandate] and children, often from minority and low income backgrounds, who are too young to be vaccinated.”313 Like the relevant Medicare and Medicaid statutory authorities with respect to the CMS mandate that the Secretary had long used to implement federal health-related regulations for providers and suppliers, the district court noted that the authority under Section 641A has long been used by the Secretary to implement past health and safety standards related to the Head Start program. These include standards requiring staff to be screened for communicable diseases, providing for appropriate treatment of children with HIV, requiring minimal spacing between infant cribs, and requiring exclusion of children with certain contagious illnesses.314 Plaintiffs have appealed the district court’s order to the Sixth Circuit.
