Human rights are rights inherent to all human beings, irrespective of their nationality, gender, language, colour, religion, ethnicity or any other grounds. These rights are considered as inalienable and universal. Human rights are often expressed and guaranteed by law, in the forms of declaration, covenants, customary international law, general principles and other sources of international law which 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 numerous human rights conventions under the framework of the United Nations and the regional systems in Africa, the Americas and Europe have led to the creation of a wide range of mechanisms for monitoring compliance with international human rights laws. The paper is intended to analyse the international mechanism for the violation of human rights under various treaty based bodies and charter based bodies working under United Nations.
