En in recent years, in the framework of international human rights law, progress has been made in protecting and claiming the rights of LGBTI persons, 1 in the case of Advisory Opinion OC-24/17, which represents one before and one after in the framework of the recognition of the rights to equality and non-discrimination of the LGBTI community. In this landmark decision, the Court stated that the American Convention on Human Rights protects rights such as name change, rectification of public registers and identity documents in the framework of the protection of gender identity; it also extended existing legal mechanisms to same-sex couples’ marriage. This resolution has involved a number of internal approaches and discussions in the various states party to the American Convention. The aim of this Article is to analyse the content of the advisory opinion on equal marriage under the Constitution of the Republic of Ecuador, as well as the obligations assumed by the State within the framework of the international community.
