Both are correct. In general sense, the ‘tribunals’ are not courts of normal jurisdiction, but they have very specific and predefined work area.
The basic objective of the administrative tribunals is to take out certain matters of disputes between the citizen and government agencies of purview of the regular courts of law and make the dispute redressal process quick and less expensive.
The Central Administrative Tribunal has been established for adjudication of disputes with respect to recruitment and conditions of service of persons appointed to public services and posts in connection with the affairs of the Union or other local authorities within the territory of India or under the control of Government of India and for matters connected therewith or incidental thereto.
The procedure is carried on in accordance with the principles of natural justice and the court procedure, namely the Civil Procedure Code, 1908, and the Indian Evidence Act, 1872, does not apply to these proceedings.
National Green Tribunal Act, 2010 (NGT) is an Act of the Parliament of India which enables creation of a special tribunal to handle the expeditious disposal of the cases pertaining to environmental issues. It draws inspiration from the India's constitutional provision of Article 21, which assures the citizens of India the right to a healthy environment.
It would mainly deal with civil cases and is not bound to follow the procedural law under Code of Civil Procedure, 1908, but shall be guided by principles of natural justice.
