The diverse grounds on which the writ is claimed by the petitioners need not be Bet out, because, at the hearing of the petition, counsel for the petitioners has restricted his argument to the following four heads: (1) that the scheme violates the equal protection clause of the Constitution, because only fourteen out of a total of thirty one routes on which stage carriages were plied for public transport in the Anekal area were covered by the scheme and that even from among the operators on the fourteen routes notified, two operators were left out, thereby making a flagrant discrimination between the operators even on those fourteen routes; (2) that by Chapter IVA of the , Parliament had merely attempted to regulate the procedure for entry by the States into the business of motor transport in the State, and in the absence of legislation expressly undertaken by the State of Mysore in that behalf, that State was incompetent to enter into the arena of motor transport business to the exclusion of private operators; (3)that the Chief Minister who heard the objections to the scheme was biased against the petitioners and that in any event, the objections raised by the operators were not considered judicially; and (4) that the Chief Minister did not give " genuine consideration " to the objections raised by the operators to the scheme in the light of the conditions prescribed by the Legislature.
