On July 3, 2024, Judge Louis Guirola, Jr. of the federal district court in Mississippi issued a nationwide preliminary injunction prohibiting the U.S. Department of Health and Human Services (HHS) from “enforcing, relying on, implementing, or otherwise acting on” the gender identity provisions of a HHS Final Rule that purported to implement Section 1557 of the Patient Protection and Affordable Care Act (ACA) and was set to go into effect on July 5, 2024. The injunction was sought by a plaintiff group comprised of fifteen individual states that alleged the Final Rule violates existing statutory and constitutional law. The breadth of the injunction includes 42 C.F.R. §§ 438.3, 438.206, 440.262, 460.98, and 460.112; 45 C.F.R. §§ 92.5, 92.6, 92.7, 92.8, 92.9, 92.10, 92.101, 92.206-211, 92.301, 92.303, and 92.304 “in so far as these regulations are intended to extend discrimination on the basis of sex to include discrimination on the basis of gender identity.” While the injunction halts the gender identity provisions of the 2024 Final Rule, the remaining provisions of the 2024 Final Rule remain in effect.
