Senior advocate Pradeep Sancheti, appearing for Youth for Equality, referred to the Supreme Court's guidelines on reservations which said it cannot exceed 50 per cent of the total seats.
He also contended that it cannot be granted on the basis of religion.
Sancheti said the state government had not provided comparative data about population and backwardness of Muslims and Marathas vis-a-vis other communities. He questioned the government's decision to introduce reservations "in a hurry" when Assembly elections were due.
Tirodkar and other petitioners, opposing the reservations, argued that Marathas and Muslims were not backward Communities.
Tirodkar contended that 75 per cent of cooperative sugar factories and as many of educational institutions in Maharashtra were controlled by Marathas. Also, they owned nearly 75 per cent of the land in the state.
Citing a report of the National Commission for Backward Classes in year 2000, he said Marathas were socially advanced and thus cannot be included in the list of backward classes.
He said the Commission, while rejecting the claim of Marathas for inclusion in the list of backward classes, said they had played a pioneering role in shaping socio-cultural and political history of modern Maharashtra and had been in the forefront of many spheres of the state's development.
