The Y.Y v. Turkey decision deals with the process of gender recognition, which is one of the many pressing legal issues trans communities are struggling with in Europe. In its previous decision, the European Court of Human Rights has found that the State’s failure to modify the birth certificate of a person by recognizing the preferred gender constitutes a violation of the right to private life guaranteed by art. 8. For the first time, in Y.Y. v. Turkey, the Court examines the domestic requirements – in this case the sterilization requirement – which are necessary to obtain the legal recognition of the preferred gender.
