All human rights derive from the dignity and worth inherent in the human person. The concept of human rights acknowledges that every single human being is entitled to enjoy his or her human rights without distinction as to race, colour, sex, language, religion, political or other opinion, national or social origin, property, birth or other status. Human rights are legally guaranteed by human rights law, which is expressed in treaties, customary international law, bodies of principles and other sources of law. Human rights law places an obligation on States to act in a particular way and prohibits States from engaging in specified activities, thereby clarifying and protecting formally the rights of individuals and groups. It is noteworthy that human rights law applies in peace and in war. The 1948 Universal Declaration of Human Rights (UDHR) together with the 1966 International Covenants on Civil and Political Rights (ICCPR) and Economic, Social and Cultural Rights (ICESCR) are known as the International Bill of Rights.
