The Evolution of Same-Sex Marriage Case Law in Europe

Abstract The number of countries allowing same-sex marriage is gradually increasing. Currently, 37 countries have laws regulating same-sex marriages, specifying their status and/or the possibility of adopting children. These solutions counter discrimination against same-sex couples and are part of the protection of human rights. Against the background of other countries, the pan-European tendency to accept the institution of same-sex marriage is garnering positive attention, although it is still controversial in some countries. Regulations of European law and the case law of the Court of Justice of the European Union, the European Court of Human Rights and the constitutional courts, which play an essential role in anti-discrimination measures and are in favour of respecting human rights, provide crucial support. This article discusses the evolution of the jurisprudence of the ECtHR, the CJEU and the national courts of selected countries (Slovenia, Spain, Portugal, Germany and Austria) concerning same-sex marriage. It highlights how recognising the right to same-sex marriage does not come at the expense of the rights of others or the public interest.
