K. J. SHETTY, C. J. ( 1 ) A Division Bench of this Court in Udai Bhan Singh Chauhan v. Union of India, 1986 0 UPLBEC 329 while disagreeing with the view taken by another Division Bench in M. B. Shukla v. Union of India, 1986 0 UPLBEC 317 : (1986 Lab IC 1034) has referred the following two questions for the opinion of a larger Bench : (1) Whether Section 28 read with Section 14 (1) of the Administrative Tribunals Act, 1985 (Central Act 13 of 1985) excludes the jurisdiction, power and authority of this Court exercisable under Article 226/227 of the Constitution in this behalf? (2) Whether action in writ jurisdiction under Article 226 or Article 227 of the Constitution in relation to this subject matter is "proceeding" within the meaning of the expression used in Section 29 (1) of the Act and, as such, stands transferred on the appointed date of the Central Administrative Tribunal? ( 2 ) THIS Full Bench, however, has been constituted to dispose of the entire case of Udai Bhan Singh Chauhan along with other connected writ petitions. ( 3 ) BEFORE we consider the aforesaid questions, it will be necessary to examine the view taken by this Court in the case of M. B. Shukla. There the question arose as to whether the High Court has got jurisdiction to entertain writ petition under Art. 226 of the Constitution after the Central Administrative Tribunal has been constituted under the Administrative Tribunals Act, 1985 (called shortly the "act" ). Mr. R. M. Sahai, J. speaking for the Bench observed that the High Courts under the Constitution exercise two powers one arising out of law framed by the appropriate legislature, Central or State, and the other constitutional. Former can be regulated, withdrawn, whittled or expanded but latter being prerogative in nature essential for society governed by rule of law cannot be rendered dormant by legislation express or implied. While examining the scope of S. 29 (1) of the Act, learned judge observed that proviso to S. 29 (1) if read in proper perspective leaves hardly any scope for doubt that it was never the legislative intent to transfer a writ petition since the writ proceeding cannot be deemed to have been included in the word "proceeding" used in S. 29 (1 ). ( 4 ) TO put it shortly what was held in M. B. Shuklas case, (1986 Lab IC 1034) was that a High Court could continue to entertain writ petition under Art. 226 of the Constitution in relation to service matters although the Central Administrative Tribunal has been constituted to deal with such matters under the Act. ( 5 ) IN Udai Bhan Singh Chauhan case, (1986 0 UPLBEC 329), Mr. K. C. Agarwal, J. speaking for the Bench has expressed the view that the proceeding used in S. 29 (1) of the Act would include the proceeding in writ petitions under Art. 226/227 of the Constitution and this Court has no jurisdiction to entertain the writ petitions in regard to matters falling within the exclusive jurisdiction of the Central Administrative Tribunal. ( 6 ) THESE are the differing views on the scope of S. 29 (1) of the Act. Our task, however, has become simple and we need not delve deep into the matter in view of the recent decision of the Supreme Court. The view taken in Udai Singh Chauhan case, (1986 0 UPLBEC 329) is fully supported by the decision of the Supreme Court in S. P. Sampath Kumar v. Union of India (Writ Petition No. 12437 of 1985 and connected Writ Petitions) disposed of on December 9, 1986. There the validity of the Act so far it excludes the jurisdiction of the High Courts under Arts. 226 and 227 of the Constitution came up for consideration. Ranganath Misra, J. speaking, for the Constitution Bench has observed that in the scheme of administration of justice, and the purpose for which the Tribunals or required to be constituted, they have been contemplated as a substitute and of supplemental to the High Courts, and it would be a retrograde step to provide Tribunal as an additional forum from where parties could again go to High Court. It was further observed :"what, however, has to be kept in view is that the Tribunal should be a real substitute of the High Court - not only in form and de jure but in content and de facto. As was pointed out in Minervas Mills, ( AIR 1980 SC 1789 ) the alternative arrangement has to be effective and efficient and also capable of upholding the constitutional limitations. As was pointed out in Minervas Mills, ( AIR 1980 SC 1789 ) the alternative arrangement has to be effective and efficient and also capable of upholding the constitutional limitations. "the learned Judge has also suggested to make certain changes in the composition of the Tribunal particularly, in regard to the class of persons to be appointed as Chairman or Vice-Chairman and other members. ( 7 ) MR. Bhagwati, Chief Justice, in his concurring judgement has said :"the exclusion of the jurisdiction of the High Court under Arts. 226 and 227 by any law made by Parliament under Cl. (1) of Art. 323-A is, therefore, specifically authorised by the constitutional amendment enacted in Cl. (2) (d) of that Article. " ( 8 ) THE learned Chief Justice has further emphasized that the law excluding the jurisdiction of the High Court under Arts. 22 and 227 must set up another effective institutional mechanism or authority and vest " the power of judicial review in it. He has also indicated some measures to ensure proper selection of the members of the Tribunal so that it may have the competence, objectivity and impartiality in order to inspite confidence in the public mind. But it has been clearly stated that the judgement will operate only prospectively and will not invalidate appointments already made to the Administrative Tribunal. ( 9 ) WE must, therefore, hold that upon the constitution of the Administrative Tribunal under the Act the jurisdiction, power and authority of this Court under Arts. 226/227 stand excluded. By the operation of S. 29 (1) of the Act, every suit or other proceeding including the writ proceeding except the appeals pending in this Court shall stand transferred to the Tribunal. ( 10 ) THE decision of this Court in M. B. Shuklas case, (1986 Lab IC 1034) holding to the contrary cannot be said to have laid down the correct law. In this view of the matter, the second question as to whether action in writ jurisdiction under Arts. 226/227 is proceeding within the meaning of that expression used in S. 29 (1) of the Act becomes academic. ( 11 ) BEFORE parting with this case we have to note the submission made by Sri R. R. Yadav, learned counsel for the petitioner in Writ Petition No. 3839 of 1985 (Sheo Bahadur Yadav v. The Union of India ). 226/227 is proceeding within the meaning of that expression used in S. 29 (1) of the Act becomes academic. ( 11 ) BEFORE parting with this case we have to note the submission made by Sri R. R. Yadav, learned counsel for the petitioner in Writ Petition No. 3839 of 1985 (Sheo Bahadur Yadav v. The Union of India ). The counsel relying upon the judgement of the Supreme Court in S. P. Sampath Kumar , 1987 0 Labic 222 urged that the Act as it stands ought to be declared as void unless necessary amendments suggested by the Supreme Court are carried out by the Central Government before March 31, 1987 and in the event of the Central Government not doing so, the petitioner shall be given liberty to revise his writ petition. We do not think it is necessary to give any such Liberty to the petitioner. It has been clearly stated by the Supreme Court in the said case that the judgement will operate only prospectively and will not invalidate the appointments already made to the Administrative Tribunals by the Central Government. However, it is open to the petitioner to take such steps as he feels after March 31, 1987. ( 12 ) BEFORE concluding, we must also point out that the writ petitions relating to service matters filed after November 1, 1985 will have to be dismissed with liberty to the parties to approach the Central Administrative Tribunal and the writ petitions filed earlier to the said date shall stand transferred to the Central Administrative Tribunal for disposal in accordance with law. ( 13 ) WE direct accordingly. Order accordingly. .
