 the Supreme Court in respect of powers of the National Human Rights Commission in the case of N.C. Dhoundial v. Union of India and Ors.: (2004) 2 SCC 579 (at page 586):-

―14. We cannot endorse the view of the Commission. The Commission which is an 'unique expert body' is, no doubt, entrusted with a very important function of protecting the human rights, but, it is needless to point out that the Commission has no unlimited jurisdiction nor does it exercise plenary powers in derogation of the statutory limitations. The Commission, which is the creature of statute, is bound by its provisions. Its duties and functions are defined and circumscribed by the Act. Of course, as any other statutory functionary, it undoubtedly has incidental or ancillary powers to effectively exercise its jurisdiction in respect of the powers confided to it but the Commission should necessarily act within the parameters prescribed by the Act creating it and the confines of jurisdiction vested in it by the Act.‖ (underlining added)
