the State and held that the impugned schemes and notifications were A valid in law. The Division Bench while allowing the appeals observed: "In consequence, we allow these appeals, set aside the order oft he learned Single Judge and hold that the impugned Schemes and notifications are valid in law. The learned Single Judge has said in his judgment that individual peti· tions had raised some additional and separate grounds for B questioning their exclusion from certain routes. He, however, felt that it was not necessary to consider individual cases of petitioners as all the writ petitions could be decided on .general grounds common to all the petitions emerg\ng from admitted facts. The individual grounds must now be considered by the learned Single Judge. He, however, is no longer available in this Court and the papers of these cases c will be laid before the Hon'ble the Chief Justice for nominating a Bench." the correctness of the view taken by the Division Bench has been assailed in these appeals. Before dealing with the contentions ad.· vanced, we may refer to the relevant l)rovisions of the Act as they existed at the relevant time. Chapter IVA was inserted in the Act by the Motor Vehicles (Am.ndment) Act, 1956 (Act 100 of 1956). The D said chapter came into force with effect from February 16, 1957 and consisted at the relevant time of sections 6BA to 68 I.· Section 68A contains definitions. According to clause (b) of that section, "State transport undertaking" means any undertaking providing road transport service, where such undertaking is carried on by,-(i) the Central Government or a State Government; (ii) any Road Transport Corporation established under section 3 of the Road Transport CorporaE tions Act, 1950; (iii) the Delhi Road Transport Authority established under section 3 of the Delhi Road Transport Authority Act, 1950; (iv) any municipality or any corporation or company owned or controlled by the State Government. Section 68B provides that the proviions of Chapter IVA and the rules and orders made thereunder shall have effect notwithstanding anything inconsistent therewith contained in Chapter IV of this Act or in any other law for the time F · being in force or in any instrument having effect by virtue of any such law. Se:;tions 68C nnd 680 at the relevant time read as under : "68C. Where any State transport undertaking is of opinion that for the purpose of providing an efficient, adeuate, economical and properly co-ordinated road transport service, it is necessary in the public interest that road G transport services in general or any particular class of such service in relation to any area or route or portion thereof should be run and operated by the State transport undertaking, whether to the exclusion, complete or partial, of other persons or otherwise, the State transport undertaking may prepare a scheme giving particulars of the nature of the services proposed to be rendered, the area or route pro~ posed to be covered and such other particulars respectina H theretC? as may be prescribed, and shall cause every such scheme to be t:ublished in the Official Gazette and also in
