X and Others v. Austria 53 ILM 64 was a human rights case that was decided in 2013 by the European Court of Human Rights (ECtHR). The case concerned whether the Government of Austria had discriminated against Austrian citizens who were in same-sex relationships because the wording of the Austrian Civil Code (German: "Allgermeines Bürgerliches Gesetzbuch") did not permit unmarried same-sex couples access to legally granted second-parent adoptions, whereas it was available to unmarried heterosexual couples.
