Mas and ERC leader Oriol Junqueras signed an agreement by which the ERC would support the CiU on sovereignty issues while on other matters it might oppose it. The two leaders drafted the Declaration of Sovereignty and of the Right to Decide of the Catalan People, which was adopted by the parliament at its first sitting in January 2013. The declaration stated that "the Catalan people have, for reasons of democratic legitimacy, the nature of a sovereign political and legal subject", and that the people had the right to decide their own political future.
