There are two questions which arise for consideration in these writ petitions and they have been succinctly set out in the judgment of Ranganath Misra, J. The first question is whether the exclusion of the jurisdiction of the High Court under Articles 226 and 227 of the Constitution in service matters specified in section 218of the Administrative Tribu nals Act, 1985 (hereinafter referred to as the impugned Act) and the vesting of exclusive jurisdiction in such service matters in the Administrative Tribunal to be constituted under the impugend Act, subject to an exception in favour of the jurisdiction of this Court under Articles 32 and 136, is unconstitutional and void and in any event, even if the first question be answered against the petitioners and in favour of 441 the Government, the second question required to be consid ered is, whether the composition of the Administrative Tribunal and the mode of appointment of Chairman, Vice Chairmen and members have the effect of introducing a con stitutional infirmity invalidating the provisions of the impugned Act.
