“Universal human rights are often expressed and guaranteed by law, in the forms of treaties, customary international law , general principles and other sources of international law. International human rights law lays down obligations of Governments to act in certain ways or to refrain from certain acts, in order to promote and protect human rights and fundamental freedoms of individuals or groups.

The principle of universality of human rights is the cornerstone of international human rights law. This principle, as first emphasized in the Universal Declaration on Human Rights in 1948, has been reiterated in numerous international human rights conventions, declarations, and resolutions. The 1993 Vienna World Conference on Human Rights, for example, noted that it is the duty of States to promote and protect all human rights and fundamental freedoms, regardless of their political, economic and cultural systems.“
