The Supreme Court on Tuesday struck down a Colorado law banning conversion therapy for LGBT minors.

The court ruled in favor of a Christian therapist, rejecting the state's law that prohibited mental health professionals from trying to change the sexual orientation or gender identity of LGBT minors, The New York Times reported.

The 8-1 decision impacts more than 20 other states that have similar laws banning conversion therapy.

The court's majority decision said the law, as applied to talk therapy, impermissibly interferes with free speech.

“Colorado may regard its policy as essential to public health and safety,” Justice Neil Gorsuch wrote in the court's opinion. “But the First Amendment stands as a shield against any effort to enforce orthodoxy in thought or speech in this country.”

Justice Ketanji Brown Jackson was the lone dissenter, reading a lengthy summary of her opposition from the bench.

Colorado's law was adopted in 2019, and prohibits “any practice or treatment” that tries to change a minor’s “gender expressions or to eliminate or reduce sexual or romantic attraction or feelings toward individuals of the same sex.”

The law has never been enforced, but it includes fines of up to $5,000 for each violation and possible suspension or revocation of a counselor’s license. The law includes an exemption for those “engaged in the practice of religious ministry.”

Kaley Chiles, who's a Christian, sued Colorado over the law in 2022, arguing that it prevented her from working with young patients who want to live a life “consistent with their faith.”

In her court filings, she said that she was not seeking to “cure” clients of same-sex attractions or to “change” their sexual orientation, but to help them with their own stated goals, which sometimes include “seeking to reduce or eliminate unwanted sexual attractions.”
