On December 7, 2021, the U.S. District for the Southern District of Georgia, in Georgia v. Biden, No. 1:21-cv-163, granted a preliminary injunction that temporarily stayed the Biden administration’s vaccine mandate for federal contractors and subcontractors “in any state or territory of the United States of America.” The case was initially brought by Georgia, Alabama, Idaho, Kansas, South Carolina, Utah, and West Virginia. The Associated Builders and Contractors (ABC), a national trade organization, intervened on the side of the plaintiffs. The seven states and ABC requested a preliminary injunction staying Executive Order (EO) 14042 and associated FAR clauses and Guidance, which require federal contractors and subcontractors to have their employees provide proof of vaccination in order to work on or in connection with federal contracts and also impose mask and social distancing requirements. The court granted the preliminary injunction and stayed the federal contractor vaccine mandate nationwide.

On November 30, 2021, the United States District Court for the Eastern District of Kentucky, in Kentucky v. Biden, et al., No. 3:21-cv-00055, granted a preliminary injunction limiting the enforcement of the federal vaccine mandate for some federal contractors and subcontractors. The preliminary injunction was requested by the Commonwealth of Kentucky, the State of Ohio, and the State of Tennessee. As a result, the court enjoined the federal government “from enforcing the vaccine mandate for federal contractors and subcontractors in all covered contracts in Kentucky, Ohio, and Tennessee” pending further briefing and a full resolution of the case on its merits.
