Kansas state district judge Carl Folsom III granted a temporary injunction blocking enforcement of a recently approved Kansas law that banned gender-transition treatments for minors. The injunction was issued in response to a lawsuit filed by the parents of two teenagers who want to continue gender-transition treatment with medicines.

The Kansas law prohibits gender-affirming medical treatments such as hormone therapies and puberty suppressants for transgender youth diagnosed with gender dysphoria. The Republican-controlled state legislature passed the measure in January over Governor Laura Kelly's veto.

The parents sued to halt the law, arguing they have the right to make decisions regarding the health of their children. The lawsuit argues that the Kansas law violates the state constitution.

Folsom concluded that the plaintiffs are likely to prevail based on the right to personal autonomy set out in Section 1 of the Kansas Constitution Bill of Rights and a parent's fundamental right to make medical decisions for their children. Folsom was appointed by Kelly.

The American Civil Liberties Union is representing the plaintiffs in the lawsuit. "This is an enormous relief to our clients and families across the state of Kansas," attorney Harper Seldin said.

Kansas Attorney General Kris W. Kobach plans to appeal the decision. "This is a stark example of judicial activism," Kobach said.

The U.S. Supreme Court ruled last year that states can ban gender-affirming care for minors. That ruling came before Folsom issued the injunction, which is based on the Kansas state constitution rather than federal law.
