Kaylee Gain has been hospitalized since a March 8 fight near Hazelwood East High School in which another teen repeatedly slammed her head to the ground.
The suit alleges the Pennsylvania nursing center where the victim lived failed to remove the nurse from his care even after she had bullied him and called him a derogatory term.
The rulings were a victory for LGBTQ groups, medical professionals and civil liberties advocates who oppose conservative efforts to restrict gender-affirming care for trans youth.
