WASHINGTON — In a blow to LGBTQ rights, the Supreme Court on Tuesday ruled that Colorado's ban on conversion therapy aimed at youths struggling with their sexual orientation or gender identity violates the free speech rights of a conservative Christian therapist.

The 8-1 decision in favor of therapist Kaley Chiles on her claim brought under the Constitution's First Amendment is likely to have national implications — more than 20 states have similar laws. It could also have an impact on other forms of medical treatment that involve speech.

n deciding the case, the court embraced Chiles’ argument that the Colorado law banning conversion therapy regulates speech, not conduct, as Colorado had argued. As such, the measure is not like other health care regulations that focus on conduct, the court concluded. The case, decided on the global Transgender Day of Visibility, will now return to the lower courts.

"I hope this win for free speech will fuel a greater pursuit of truth," Chiles told reporters after the ruling. "Because of today's ruling, families will have more options and states won't be able to shut those options down," she added.
