HELENA, Mont. (AP) — Two transgender children, their families and allied health care providers are challenging a Montana law that would ben gender-affirming medical care for transgender youth. The lawsuit filed Tuesday in Missoula argues that the law set to be implemented Oct. 1 only affects transgender people and serves no purpose other than to intentionally burden a transgender person’s ability to seek necessary care. The lawsuit asks a judge to block enforcement of the new law, and argues that it violates parental rights and is unconstitutional. The attorney general’s office says the legislation provides commonsense protections for children.
