In an 8-1 decision, the U.S. Supreme Court has ruled against a law that banned “conversion therapy” for LGBTQ children in Colorado. The challenge to Colorado’s ban is led by a Christian licensed counselor, Kaley Chiles, who argued the ban is a violation of her First Amendment rights to free speech and religion. Supreme Court Justice Ketanji Brown Jackson was the only dissenting vote.

The ACLU of Colorado said in a statement, “The Supreme Court’s decision in this case is a major blow to the rights of LGBTQ+ youth not only in Colorado, but across our country. Conversion therapy has no place in our country. Attempts to change an individual’s sexual orientation, gender identity, or gender expression causes severe, lasting psychological harm to LGBTQ+ youth.”

So-called conversion therapy has been widely discredited by medical organizations, including the American Medical Association, the American Psychological Association and the American Academy of Pediatrics.
