The Philadelphia-based Catholic Medical Association Aug. 26 joined in a lawsuit challenging the Biden administration’s mandate that doctors and hospitals perform gender-transition procedures on any patient despite any moral or medical objections of the doctor or health care facility. “Biological identity must remain the basis for treating patients,” said Dr. Michael Parker, president of the association, a national, physician-led community of more than 2,300 health care professionals in 114 local guilds. The suit was filed Aug. 26 in U.S. District Court by Alliance Defending Freedom, a national faith-based nonprofit in Arizona that focuses on legal advocacy. Other joining the suit are Dr. Jeanie Dassow, a Tennessee OB-GYN doctor who specializes in caring for adolescents, and the American College of Pediatricians, made up of more than 600 physicians and other health care professionals in 47 states who treat children. A news release said the association and the college joined the suit on behalf of their members. It was filed in U.S. District Court for the Eastern District of Tennessee in Chattanooga.
