After undergoing a sex affirmation procedure, Norrie registered as “non-specific” with the NSW Registrar. After initially approving this registration, the NSW informed Norrie that the registration was invalid. The Administrative Decisions Tribunal of New South Wales agreed with this determination, and the Tribunal’s appeal panel dismissed Norrie’s appeal. At this point, Norrie appealed to the Court of Appeal of New South Wales, which remitted the matter to the Tribunal for determination of Norrie’s sex classification. The Registrar appealed to the High Court. The issue on appeal to the High Court was whether the NSW Registrar was in fact confined to registrations of “male” or “female,” which would preclude Norrie’s registration as “non-specific.” The High Court noted that the Transgender (Anti-Discrimination and Other Acts Amendment) Act of 1996, which amended the Births, Deaths, and Marriages Registration Act of 1995, recognized “ambiguities.” Furthermore, the Court pointed to its holding in AB v. Western Australia, where it stated that "the sex of a person is not ... in every case unequivocally male or female." On this basis, the High Court held that individuals do not have to affirmatively select “male” or “female” following a sex affirmation procedure, and may instead register as “non-specific” with the NSW Registrar.
