( 1 ) THE Constitution (First Amendment) Act, 1951 which introduced article 31-A into the Constitution with retrospective effect, and S. 3 of the Constitution (Fourth Amendment) Act, 1955 which substituted a new clause (1), sub-clauses (a) to (c), for the original clause (1) with retrospective effect, do not damage any of the basic or essential features of the Constitution or its basic structure and are valid and constitutional, being within the constituent power of the Parliament. ( 2 ) S. 5 of the Constitution (First Amendment) Act, 1951 introduced Article 31-B into the Constitution which reads thus : 31-B. Without prejudice to the generality of the provisions contained in Article 31-A, none of the Acts and Regulations specified in the Ninth Schedule nor any of the provisions thereof shall be deemed to be void, or ever to have become void, on the ground that such Act, regulation or provision is inconsistent with, or takes away or abridges any of the rights conferred by, any provisions of this Part, and not withstanding any judgment, decree or order of any court or tribunal to the contrary, each of the said Acts and Regulations shall, subject to the power of any competent legislature to repeal or amend it, continue in force. In Kesavananda Bharati decided on 24/04/1973 it was held by the majority that Parliament has no power to amend the Constitution so as to damage or destroy its basic or essential features or its basic structure. We hold that all amendments to the Constitution which were made before 24/04/1973 and by which the 9th Schedule to the Constitution was amended from time to time by the inclusion of various Acts and Regulations therein, are valid and constitutional. Amendments to the Constitution made on or after 24/04/1973 by which the 9th Schedule to the Constitution was amended from time to time by the inclusion of various Acts and Regulations therein, arc open to challenge on the ground that they, or any one or more of them, are beyond the constituent power of the Parliament since they damage the basic or essential features of the Constitution or its basic structure. We do not pronounce upon the validity of such subsequent constitutional amendments except to say that if any Act or Regulation included in the 9th Schedule by a constitutional amendment made after 24/04/1973 is saved by article 31-C as it stood prior to its amendment by the 42nd Amendment, the challenge to the validity of the relevant Constitutional Amendment by which that Act or Regulation is put in the 9th Schedule, on the ground that the Amendment damages or destroys a basic or essential feature of the constitution or its basic structure as reflected in Articles 14, 19 or 31, will become otiose. ( 3 ) ARTICLE 31-C of the Constitution, as it stood prior to its amendment by S. 4 of the Constitution (42nd Amendment) Act, 1976, is valid to the extent to which its constitutionality was upheld in Kesavananda Bharati. Article 31-C, as it stood prior to the Constitution (42nd Amendment) Act does not damage any of the basic or essential features of the Constitution or its basic structure. ( 4 ) ALL the Writ Petition and Review Petition relating to the validity of the Maharashtra Agricultural Lands Ceiling Acts are dismissed with costs. The stay orders granted in these matters will stand vacated. We quantify the costs at rupees twenty thousand which will be borne equally by the petitioners in Writ Petition Nos. 656-660 of 1977 ; 512-533 of 1977; and 505 to 5) 1 of 1977. The costs will be payable to the Union of India and the State of Maharashtra in equal measure. ( 5 ) WRIT Petition No. 63 of 1977 (Baburao Samant v. Union of India) will be set down for hearing. ( 6 ) REASONS for this Order will follow later.
