The United Nations Convention on the Rights of Persons with Disabilities and its Optional Protocol were approved on December 13, 2006, at the United Nations Headquarters in New York and were opened for signature on March 30, 2007. The preparatory process was extraordinary because of the participation of civil society. It was the first time that the presence of organisations of people affected by the treaty and of people with disabilities was allowed. The new paradigm of disability, conceptualised socially from human rights, has as its main objective the relationship of people with disabilities with the environment that discriminates against them, for which the Convention assumes the need to protect their rights and not their limitations, with a revolutionary Article 12 of the CRPD that develops ‘equal recognition as a person before the law’.
