On 8 February 2011, the European Court of Human Rights decided to merge and accept two cases of four couples regarding a breach of article 8 (respect of private and family life) combined with article 14 (freedom from discrimination) and article 13 (effective remedy) of the European Convention on Human Rights. The cases were brought to the ECHR as a result of the Greek state introducing cohabitation agreement legislation that specifically and expressly excluded same-sex couples. The ECHR gave Greece until 31 May 2011 to submit its observations. On 7 November 2013, the ECHR ruled in "Vallianatos and Others v. Greece" that excluding same-sex couples from cohabitation agreements is discriminatory. On 12 November, PASOK announced its intention to introduce a bill extending the cohabitation agreement law to same-sex couples.
