Maine’s top prosecutor is opposing an Alabama law targeting those who assist youth in seeking out gender transition treatment.

Maine Attorney General Aaron Frey said Thursday he was joining a group of 21 attorneys general who have filed an amicus brief to oppose the legislation. It was preliminarily blocked by the district court.

Under the proposed law, anyone who assists transgender youth in seeking out treatments like puberty blockers or hormone therapy in Alabama would be charged with a felony punishable by up to 10 years in prison and a fine of up to $15,000.

“Gender-affirming from a caring medical professional may mean the difference between life and death for a young trans person,” said Attorney General Frey. “SB184 is an unconscionable, discriminatory interference between a medical professional and their patient.”

Republicans and conservative activists say the law is aimed at safeguarding children, as well as protecting parental rights.
