In the first place Counsel for the petitioners have contended that under section 30(2) of the Principal Act of 1910 prior to its amendment by U.P. Ordinance No. 4 of 1979 and U.P. Act 13 of 1979 it was open to the respondents to adopt either one or the other method of granting FL 2 licences and determine the licence fee payable by the grantee accordingly, that is to say the respondents could grant the licence "either by auction or by calling tenders" and once a particular mode was adopted it was incumbent upon them to apply the same for the purpose of determining the sum payable by the grantee; in other words the contention has been that it was not open to them to adopt a combination of two or more methods and claim "assessed fee" in addition to "fixed fee" and therefore the instant attempt on the part of the respondents to levy and recover the "assessed fee" in addition to "fixed fee" would be illegal and without authority of law.
