Tennessee Governor Bill Haslam on Wednesday signed a controversial bill into law that allows mental health therapists and counselors to turn away LGBT clients.

“After considerable thought and discussion with counselors both for and against the bill, I have decided to sign Senate Bill 1556,” Haslam said in a signing statement. “There are two key provisions of this legislation that addressed concerns I had about clients not receiving care. First, the bill clearly states that it ‘shall not apply to a counselor or therapist when an individual seeking or undergoing counseling is in imminent danger of harming themselves or others.’ Secondly, the bill requires that any counselor or therapist who feels they cannot serve a client due to the counselor’s sincerely held principles must coordinate a referral of the client to another counselor or therapist who will provide the counseling or therapy.”

“I believe it is reasonable to allow these professionals to determine if and when an individual would be better served by another counselor better suited to meet his or her needs,” he added.

The bill states that counselors can refuse to treat clients based on their “sincerely held principles,” a change from the bill's original language of “sincerely held religious beliefs.”

Opponents say the measure could negatively impact young LGBT people.

Tennessee lawmakers are also considering legislation that would outlaw transgender people from accessing the bathroom that matches the gender they identify with.
