by a public charitable or religious trust. AccMding to him though s. 9 refers to all agricultural income of Muslim. trusts "referred to in s. 3 of the Musalman Wakf Validating Act, 1913, (Act VI of 1913), the wakfs contemplated by s. 3 of the said Act (Act VI of 1913) include not merely Wakf-a/al-aulad but also other wakfs where property has been permanently dedicated for any purposes recognised by B the Musalmau Law as religious, pious or charitable and this, he argued, becomes clear from sub-clause (a) of s. 3 which speaks of wakf created by a Muslim for the maintenance and support wholly or partially of his family, children or descendants; in other words, according to Mr. Mukherjee, s. 9 of the. Act is not confined to c Muslim trusts known as wakf-alal-aulad but is applicable to all wakfs and, therefore, in case of wakfs other than wakf-alal-aulad the exemption granted by s. 9 of the Act which is in respect of all agricultural income must be regarded as discriminatory as against the exemption · granted by s. 8 ( 1) of the Act. He, therefore, nrged that s. 8 ( 1) which grants a .limited exemption would be violative of Art. 14 of D the Constitution. On the other hand, the learned Attorney-General appearing for the respondents contended that s. 9 is confined to Muslim trusts commonly known as wakf-alal-aulad and all other Muslim trusts are covered by s. 8 (1) of the Act with the result that to all such Muslim trusts, other than wakf-alal-aulad, the limited exemption is applicable. He urged that wakfs-alal-aulad do stand E in a class by themselves and as such have been dealt with by s. 9 in keeping with the objective of the Act. He further urged that sections 8 ( 1), 9 and 1(1 showed the scheme of the Act and if these provisions were considered in ligh( of the main objective of the enactment it was clear that s. 8 (1) could not be held to be discriminatory or violative of Art. 14.
