Attorneys say the administration’s push to end hormone therapy ignores decades of federal prison medical practice and puts transgender patients at risk.

In a 41-page brief filed October 8, attorney Li Nowlin-Sohl and other lawyers representing the prisoners argued that the justices should uphold an updated preliminary injunction issued this year by U.S. District Judge Royce C. Lamberth. The order followed an injunction issued last year and blocked the Bureau of Prisons from enforcing a policy implementing President Donald Trump’s executive order denying gender-affirming care to transgender people in federal prisons.
