These rights are familiar from historic bills of rights such as the French Declaration of the Rights of Man and the Citizen (1789) and the U.S. Bill of Rights (1791, with subsequent amendments). Contemporary sources include the first 21 Articles of the Universal Declaration, and such treaties as the European Convention, the International Covenant on Civil and Political Rights, the American Convention on Human Rights, and the African Charter on Human and People's Rights. Some representative formulations follow:
Everyone has the right to freedom of thought and expression. This right includes freedom to seek, receive, and impart information and ideas of all kinds, regardless of frontiers, either orally, in writing, in print, in the form of art, or through any other medium of one's choice. (American Convention on Human Rights, Article 13.1)
Everyone has the right to freedom of peaceful assembly and to freedom of association with others, including the right to form and to join trade unions for the protection of his interests (European Convention, Article 11).
Every citizen shall have the right to participate freely in the government of his country, either directly or through freely chosen representatives in accordance with the provisions of the law. 2. Every citizen shall have the right of equal access to the public service of his country. 3. Every individual shall have the right of access to public property and services in strict equality of all persons before the law (African Charter, Article 13).
Most civil and political rights are not absolute—they can in some cases be overridden by other considerations. For example, the right to freedom of movement can be restricted by public and private property rights, by restraining orders related to domestic violence, and by legal punishments. Further, after a disaster such as a hurricane or earthquake free movement is often appropriately suspended to keep out the curious, to permit access of emergency vehicles and equipment, and to prevent looting. The International Covenant on Civil and Political Rights permits rights to be suspended during times “of public emergency which threatens the life of the nation” (Article 4). But it excludes some rights from suspension including the right to life, the prohibition of torture, the prohibition of slavery, the prohibition of ex post facto criminal laws, and freedom of thought and religion.
