Supreme Court Justice Samuel Alito has revealed that he has a "pretty good idea" of who was responsible for the leak of his unpublished draft opinion last year, which indicated that the Supreme Court was poised to roll back abortion rights. Alito does not have the proof needed to name the leaker, and the incident has not been officially investigated. The opinion stated that "Roe and Casey must be overruled" and that "the Constitution makes no reference to abortion, and no such right is implicitly protected by any constitutional provision."
