HARRISBURG (AP) – A lawsuit has been filed in a bid to undo anti-discrimination protections for gay and transgender people, saying PA‘s two-year-old regulation is illegal because it goes beyond what lawmakers intended or allowed. The lawsuit comes amid a national debate over transgender students competing in women’s sports, and was filed in Commonwealth Court last Thursday. If the lawsuit is successful, the PA Human Relations Commission would no longer be able to investigate complaints about discrimination involving sexual orientation, gender identity, and gender expression. The plaintiffs’ lawyers also say a favorable ruling in court would bar transgender student athletes from competing in women’s high school sports in PA. The plaintiffs include two PA school districts, two Republican state lawmakers, along with three parents and seven students.
