The Colorado state Senate on Monday passed House Bill 1129, which bans licensed mental health professionals from offering conversion therapy to people under the age of 18.

The action send the bill back to the House for their take on a minor amendment adopted during Senate debate on March 21.

The Senate voted 21-13, with three Republicans voting in favor along with the chamber’s Democrats.

“I applaud the House and the Senate for their bipartisan support of this measure,” Daniel Ramos, executive director of the LGBTQ advocancy group One Colorado, said in a statement after the measure’s passage.

“Protecting our LGBTQ youth is not a partisan issue,” Ramos said. “It is my sincere hope that, with this being the fifth time this measure has been introduced in the Colorado legislature, this will be the year Colorado says ‘no more’, and bans a practice on minors that is based on the false claim that being LGBTQ is a mental illness that needs to be cured.”

But Republican Sen. Owen Hill of Colorado Springs, said, “I’m worried and concerned that we’re going too far. We’re infringing on someone’s First Amendment rights” and forcing them to cancel services that patients might want.

He added: “We have associations that control this in a much better way then we in the legislature.”

Correction: A previous version said the bill would go straight to the governor. A technical amendment adopted by the Senate on March 21 means the bill has to go back to the House for concurrence.
