Most of the original grounds of attack thus do not survive and the contentions that were canvassed at the hearing by the counsel appearing for different parties are these (1) Judicial review is a fundamental aspect of the basic structure of our Constitution and bar of the jurisdiction of the High Court under Articles 226 and 227 as contained in Section 28 of the Act cannot be sustained; (2) Even if the bar of jurisdiction is upheld, the Tribunal being a substitute of the High Court, its constitution and set up should be such that it would in fact function as such substitute and become an institution in which the parties could repose faith and trust; (3) Benches of the Tribunal should not only be established at the seat of every High Court but should be available at every place where the High Courts have permanent benches; (4) So far as Tribunals set up or to be set up by the Central or the State Govern ments are concerned, they should have no jurisdiction in respect of employees of the Supreme Court or members of the subordinate judiciary and employees working in such estab lishments inasmuch as exercise of jurisdiction of the Tribunal would interfere with the control absolutely vested in 450 the respective High Courts in regard to the judicial and other subordinate officers under Article 235 of the Constitution.
