Twelve states including Arizona have filed a lawsuit in a federal district court in Louisiana challenging the Centers for Medicare & Medicaid Services interim final rule that mandates COVID-19 vaccines for workers at Medicare/Medicaid participating facilities by January 4.

Attorney General Brnovich argues that the CMS rule exceeds their statutory authority, violates the Tenth Amendment, and that the rule is arbitrary and capricious. For once, the suit doesn’t blame refugees and immigrants.

This lawsuit follows the complaint filed last week by a different group of states in a U.S. district court in Missouri also challenging the CMS interim final rule on similar grounds. For more information about the CMS rule, please refer to AzHHA’s Summary and CMS’s FAQs.
