California Governor Jerry Brown on Wednesday appealed a court injunction blocking enforcement of the state's ban on “ex-gay” therapy to minors.

The first-in-the-nation law which prohibits therapies which promise to alter the sexual orientation of minors from gay to straight was scheduled to take effect on January 1.

However, a three-judge panel of the 9th U.S. Circuit Court of Appeals postponed the law's start until it can hear a legal challenge, reversing a district court's refusal to put the law on hold.

State Attorney General Kamala Harris, working on behalf of Brown and the Medical Board of California, filed the notice of appeal with the 9th Circuit, The Los Angeles Times reported. She asked the court to look at the district court's decision, handed down by Judge Kimberly Mueller.

“Defendants wish to apprise the 9th Circuit of a related case currently pending before it … denying a motion for a preliminary injunction that would have enjoined enforcement of Senate Bill 1172,” Harris wrote. “Both appeals involve the constitutionality of Senate Bill 1172 and raise the same and/or closely related legal issues.”

The lawsuit was filed by the National Association for Research & Therapy of Homosexuality (NARTH), which strongly opposed passage of the law. The organization is represented by the Christian conservative Liberty Counsel, which has a long record of opposing LGBT rights.

Liberty Counsel Chairman Mat Staver said his organization was pursuing legal action because the law promotes “child endangerment” and “will destroy many lives.”
