" The next section 68 C which is the one most involved in the appeals runs: "Where any State Transport undertaking is of opinion that for the purpose of providing an efficient, adequate, economical and properly coordinated road transport service, it is necessary in the public interest that road 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 proposed to be covered and such other particulars respecting thereto as may be prescribed, and shall cause every such scheme to be published in the Official Gazette and also in such other manner as the State Government may direct." The first two sub sections of section 68 D enable persons affected by a Scheme published under section 68 C to file objec tions thereto before the State Government within thirty days after the publication of the Scheme.
