By IULIA FILIP (CN) - Therapists who purportedly counsel patients into heterosexuality filed a federal complaint against California's ban on anti-gay teen therapy. Known as Senate Bill 1172, the law prohibits licensed mental health professionals, such as psychiatrists, psychologists and family therapists, from using sexual orientation change therapy and other "reparative" methods with clients under the age of 18. The ban targets any practices that seek to change sexual orientation or behavior and gender expression.
