The U.S. Supreme Court on Wednesday blocked an order (pdf) that gave a transgender Virginia teen access to the same school restrooms as his male peers, which means he will not be able to use the facilities that correspond to his gender identity when classes resume in the fall.Gavin Grimm, 17, brought the case against the Gloucester county school board in 2015 over what he argued was a discriminatory policy. In April, the Fourth Circuit Court of Appeals granted him a major victory by holding that Title IX protects the rights of transgender students to use the facilities consistent with their gender identity. The court sent the case back to the trial judge for further proceedings.The high court\u0026#039;s stay of the order means Grimm\u0026#039;s school can continue to \u0022isolate and stigmatize\u0022 him, the American Civil Liberties Union (ACLU) said Thursday.Justices Ruth Bader Ginsburg, Sonia Sotomayor, and Elena Kagan dissented and said they would not have stayed the ruling. Justice Stephen Breyer sided with the court\u0026#039;s four conservatives—Chief Justice John Roberts and Justices Anthony Kennedy, Clarence Thomas, and Samuel Alito—\u0022as a courtesy\u0022 on the grounds that the ruling would \u0022preserve the status quo\u0022 while Grimm\u0026#039;s fight continues.ACLU senior staff attorney Joshua Block, who is representing Grimm, said, \u0022We are disappointed that the court has issued a stay and that Gavin will have to begin another school year isolated from his peers and stigmatized by the Gloucester County school board just because he\u0026#039;s a boy who is transgender.\u0022The ruling \u0022also suggests that four Justices—the number needed to review a case on the merits—could be willing to take the case on, possibly as soon as this fall,\u0022 wrote Amy Howe at SCOTUSBlog.Howe said:The one-page ruling indicated that the district court\u0026#039;s order (as well as an earlier ruling by the U.S. Court of Appeals for the Fourth Circuit, which hears appeals from federal district courts in Virginia) will at the very least remain on hold until the court rules on the school board\u0026#039;s petition for review, which is due on August 29. If the Justices grant review, the district court\u0026#039;s order would remain on hold until the court can hear oral arguments and issue its opinion.\u0022We remain hopeful that Gavin will ultimately prevail,\u0022 Block said Wednesday.It is the high court\u0026#039;s first ruling on the issue that has become a new frontier in LGBTQ rights.
