The American Counseling Association (ACA) on Tuesday announced that it was canceling an upcoming conference in Tennessee to protest a state law that allows therapists to turn away LGBT clients.

The law, signed by Republican Governor Bill Haslam last month, 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.

In making its announcement, ACA said that the law violates its Code of Ethics.

This law directly targets the counseling profession, would deny services to those most in need, and constitutes a dilemma for ACA members because it allows for violation of ACA's Code of Ethics,” said ACA CEO Richard Yep. “By relocating from Tennessee, ACA is standing up to this discriminatory law and we remain committed in the battle to ensure that this law does not become the national standard.”

ACA's 2017 Conference & Expo – which is projected to generate $2.5 million in visitor spending – was originally scheduled to take place in Nashville.

We thank the Nashville Convention and Visitors Corporation and the Mayor's office, who offered their support to ACA regardless of our decision to stay in or relocate from Nashville,” Yep added.

Butch Spyridon, president and CEO of the Nashville Convention & Visitors Corporation, said in a statement that the cancellation was “disappointing” but not a surprise.

This cancellation is the second one and is likely just the tip of the iceberg when you consider all the other groups that won't consider us now,” Spyridon said. “It is regrettable that all the hard work and investment to make Nashville a top destination has been unnecessarily undone by politics.”
