In 1950, the United Nations General Assembly declared that the enjoyment of civil and political rights and the enjoyment of economic, social and cultural rights are interrelated and interdependent. Following the adoption of the Universal Declaration of Human Rights it wanted to establish a Bill of Human Rights which would be binding.
Therefore it adopted two complementary texts : the International Covenant on Economic, Social and Cultural Rights and the International Covenant on Civil and Political Rights.
Including the Universal Declaration, these texts make up the International Bill of Human Rights. These joint documents lay down the fundamental rights that should be enjoyed by all persons and that are the foundation for all other United Nations Instruments as regards human rights.
Subsequently, the United Nations General Assembly also adopted Conventions on specific groups of persons : the International Convention on the Rights of the Child, and more specifically, as far as we are concerned, the Convention on the Rights of Persons with Disabilities (UNCRPD). These Conventions do not create any new rights, but they reaffirm these rights specifically for the groups of persons concerned.
