17. The only question that has to be decided in this Civil Revision Petition is as to whether the custom and usage, which results in a hereditary succession to the office of Mutawalli would continue to apply and the prohibition enacted under the Muslim Personal Law (Shariat) Application (Tamil Nadu Amendment) Act, XVIII of 1949 would cease to have effect because of the enactment of the new Wakf Act in 1995. Before proceeding further, it would be pertinent to refer to the provisions of the Wakf Act, 1995. Section 3(i) of the Wakf Act defines the term 'Mutawalli'. From the definition of the Mutawalli under the new Wakf Act, it is clear that it includes a person appointed as a Mutawalli by virtue of any custom or usage. This definition of the term 'Mutawalli' as found in the Wakf Act, 1995, therefore, would have precedence over the provisions of Muslim Personal Law (Shariat) Application (Tamil Nadu Amendment) Act, XVIII of 1949. Section 3 of the amending Act substitutes Section 2 instead of Section 2 of the Central Act XXVI of 1937. Amended Section 2 of the Central Act XXVI of 1937 has already been extracted. A comparison of Section 3(i) of the Wakf Act and Section 2 of the Central Act XXVI/1937 as amended by Tamilnadu Act XVIII of 1949 are inconsistent with each other as much as Section 3(i) of the Wakf Act,1995 recognizes Mutawalliship by custom and usage. This would automatically mean that if there is a hereditary succession to the office of Mutawalliship by custom and usage, the same can continue under the Wakf Act, 1995. A reading of the amended Section 2 of the Central Act, XXVI of 1937 would show that it prohibits applicability of custom and usage. The law applicable shall be the Muslim Personal Law (Shariat). It is common knowledge that the Muslim Personal law does not recognize the hereditary succession. There is inconsistency between the Wakf Act, 1995, which recognizes the custom and usage in appointment of Mutawallis and the amended Section 2 of the Central Act, XXVI of 1937. The amendment was introduced by Tamilnadu Act, XVIII of 1949. The amending Act had been reserved for assent of the Governor General and has received the assent. Therefore, it is valid piece of legislation enacted in conformity by Article 254(2) of the Constitution of India. However, the effect of the new Wakf Act on the amended Section 2 will have to be considered. It is here that the proviso to Article 254(2) of the Constitution of India assumes significance.
