The Council of Europe, as the leading human rights organization, has undertaken a series of initiatives to promote the protection of women against violence in the last twenty years, this has resulted in the adoption of an international act known as the Istanbul Convention. The Council of Europe's Convention on the Prevention and Fight against Violence against Women and Domestic Violence was signed in Istanbul in 2011, and in 2014 it was put into effect after being signed by ten countries, of which eight were to be members of the Council of Europe. Croatia signed the Convention in 2013, and ratified it in March 2018. Pursuant to Article 141 of the Constitution of the Republic of Croatia, all international treaties concluded, approved by the Constitution and published, which are in force, form part of the internal order and are legally binding above the law. It follows that certain regulations will have to be aligned with the Convention. In this paper, we are dedicated to the text of the Convention and we are looking which of the existing regulations protect women from domestic violence. We are referring to the controversial "gender" concept that awakened many questions in the Republic of Croatia and shaped two different notions. We put a special emphasis on the ratification of the Convention as well as on the interpretative statement given together with the Law Proposal.
