A judge has overturned a state law that prohibited gender-affirming care in prisons and other settings.

On Tuesday, a federal judge issued a preliminary injunction halting an Idaho bill that banned gender-affirming care in state prisons. This decision allows incarcerated transgender individuals in Idaho to access hormone therapy once again.

In the ruling for Robinson v. Labrador, Judge David Nye of the U.S. District Court for the District of Idaho wrote, “Plaintiffs’ Motion for Temporary Restraining Order, Provisional Class Certification, and Preliminary Injunction is hereby GRANTED. The court certifies the protected class of all incarcerated persons in custody of the [Idaho Department of Corrections] who are, or will be diagnosed with Gender Dysphoria, and are receiving, or would receive hormone therapy. The Court enjoins enforcement of [H.B. 668]’s prohibition on the use of state funds for purposes of providing hormone therapy as against the class while this lawsuit is pending.”

H.B. 668, the bill in question, prohibited the use of public funds for any gender-affirming procedures, including hormone therapy and surgeries. Sponsored by Republican lawmakers in the House State Affairs Committee, the bill was signed into law in March of this year by Governor Brad Little (R).

The injunction applies only to the use of public funds for gender-affirming care in prisons and does not extend to non-incarcerated transgender individuals or gender-affirming surgeries.

In his ruling, Judge Nye supported the injunction by highlighting the plaintiffs’ strong arguments regarding the importance of gender-affirming care, the societal impact of such restrictions, and the consequences for transgender people across the state. Although he acknowledged areas where the plaintiffs’ case was lacking, he ultimately determined that the evidence justified the injunction.

Initially, Nye had denied the request to make the lawsuit a class action. However, after receiving data showing that 54 incarcerated individuals were receiving gender-affirming care and 70 had been diagnosed with gender dysphoria, he changed his stance.

The lawsuit involves two transgender women in prison, Katie Heredia and Rose Mills, both diagnosed with gender dysphoria and undergoing hormone replacement therapy. Their care was put at risk due to H.B. 668. The case was expanded into a class action lawsuit representing all known transgender prisoners in Idaho, with the ACLU of Idaho arguing that the ban constituted an Eighth Amendment violation.

The defendants in the case include Attorney General Raul Labrador, Governor Brad Little, Idaho Department of Corrections (IDOC) director Josh Tewalt, IDOC Chief of Staff Bree Derrick, and Centurion Health of Idaho.

Paul Carlos Southwick, legal director for the ACLU of Idaho, stated, “We are grateful that this class action lawsuit will protect the rights of both our plaintiffs and all incarcerated people diagnosed with gender dysphoria. People who are serving time have a right to access health care, adequate food, and housing conditions while in the state’s care, and we are grateful those rights were upheld today.”

LGBTQ Nation reached out to both the ACLU of Idaho and the Attorney General’s office for comment but had not received a response by the time of publication. This article will be updated as necessary.
