Human rights whenever guaranteed by a written Constitution may be called as fundamental rights in the sense that a written Constitution is a fundamental law of the land, although it is not the exhaustive source of Constitutional law which is enforceable by a Court. The Constitution of India is the highest law of the land and all laws, national or local, customary or statutory, past and future draw their validity and legitimacy from it. The Preamble to the Constitution of India emphasises the principle of equality as basic to the Constitution. Equality of opportunity to all irrespective of their caste, colour, creed, race, religion and place of birth which constitutes one of the core values of the Universal Declaration of Human Rights, also forms a part of Preamble to the Constitution of India.
