In its Friday ruling allowing the law to be enforced, the court pointed to “the relative nascency of both gender dysphoria and its various modes of treatment,” as well as the state Legislature’s “express constitutional authority to regulate the practice of medicine.”

The state statute “does not unconstitutionally deprive parents of their rights or physicians or health care providers of an alleged property right in their medical licenses or claimed right to occupational freedom,” the justices said.

Nor does the law “unconstitutionally deny or abridge equality under the law because of sex or any other characteristic asserted by plaintiffs,” they wrote. 

The ACLU of Texas, which had sued to stop the law’s enforcement, in a press release described the law as “anti-transgender” and claimed that it “threatens the health and lives of Texas transgender youth.”

“We will continue to fight measures like [the law],” attorney Karen Loewy said in the release. “These youth and their families deserve no less.”

State Attorney General Ken Paxton, meanwhile, said on X after the ruling that the law “[protects] children from dangerous gender confusion procedures by prohibiting puberty blockers, cross-sex hormones, and mutilative surgeries on minors.”
