AB v Registrar of Births, Deaths and Marriages

AB, the applicant, filed an application seeking a declaration that their gender identity is recognised under the Births, Deaths and Marriages Registration Act 1995 (Cth). The Registrar of Births, Deaths and Marriages, the respondent, argued that the Act did not allow for the recognition of gender identity in the manner sought by the applicant. The Federal Court of Australia was tasked with determining whether the Act provided for the recognition of gender identity as claimed by the applicant.

The central legal issue was whether the Act permitted the recognition of gender identity in the manner sought by the applicant. The court had to consider whether the Act's provisions allowed for the recognition of a gender identity that differed from the sex assigned at birth. This involved interpreting relevant sections of the Act and determining whether the applicant's gender identity could be recognised on their birth certificate.

The court found that the Act did not provide for the recognition of gender identity in the manner sought by the applicant. It held that the Act only allowed for the recognition of sex, not gender identity. The court's reasoning was grounded in the plain language of the Act, which defined sex as the biological status of a person as male or female. The court concluded that the Act did not contemplate a situation where a person's gender identity differed from their sex assigned at birth. Consequently, the application was dismissed, and the applicant's request for a declaration recognising their gender identity was denied.
