in the sense of it not being reasonable but in the sense that it is manifestly arbitrary. (See Indian Express Newspaper (Bombay) Private Limited vs. Union of India (1985) 1 SCC 641 : A.I.R. 1986 S.C. 515. The Court when testing the constitutional validity of a piece of delegated legislation on the touch stone of Article 14 of the Constitution, can examine whether the criterion adopted is reasonable. "Reasonableness, for purposes of judging whether there was an excess of power or an arbitrary exercise of it, is really the demonstration of a reasonable nexus between the matters which are taken into account in exercising a power and the purposes of exercise of that power. See (Meenakshi Mills vs. Union of India), (1974) 1 SCC 468 : AIR 1974 SC 366, (Panipat Co-op. Sugar Mills vs. Union of India), (1973) 1 SCC 129: AIR 1973 SC 537 and (SI Syndicate vs. Union of India) (1974) 2 SCC 129 : AIR 1975 SC 460. It would, therefore, be clear from the above, that it would not be possible for this Court considering the object behind the D.C. Regulation and Appendix VII-B to hold that they are ultra vires Article 14 and 21 of the Constitution of India as being manifestly arbitrary, unreasonable and or discriminatory.
