A federal judge on Friday temporarily blocked the University of North Carolina from enforcing the state’s so-called “bathroom bill” from applying to three transgender plaintiffs in a challenge brought by LGBT rights groups. Judge Thomas D. Schroeder of the US District Court for the Middle District of North Carolina wrote that the plaintiffs had “made a clear showing” that they are likely to succeed on their claim that part of the law violates Title IX. “The University of North Carolina, its officers, agents, servants, employees, and attorneys, and all other persons acting in concert or participation with them are hereby enjoined from enforcing (the law) against the individual transgender plaintiffs until further order of the court,” Schroeder wrote. Plaintiffs in the case include two transgender students and one employee of the university. Signed into law in March, House Bill 2 bars people from entering bathrooms that do not match the sex on their birth certificates — a prohibition that opponents, including top federal law enforcement officials, have called a violation of the Civil Rights Act.
