20. Notification No.1057 (E) dated 22.07.2005, was issued plainly for giving effect to Rule 3 of the User Fee Rules, 1997, but whereas the User Fee Rules, 2008, are a comprehensive set of rules. They have provided for the base rate of fee and defined the various types of mechanical vehicles and the annual revision of rate of fee and other related matters. The User Fee Rules, 2008, have been brought into force with effect from 05.12.2008. There is no alternative for the respondents except to act in furtherance thereof. The User Fee Rules, 2008, have statutory backing and they have enforceability. The only exception carved out to their application was set out in the very preamble, that is, as respects things done or omitted to be done before such supersession. In other words after the 1997 User Fee Rules are superseded, the respondents have no authority to regulate their affairs as respect things to be done henceforth. In other words, if a contract has not been entered into or bids are not invited otherwise by 05.12.2008 by the respondents, they are bound to regulate their affairs in that respect in accordance with User Fee Rules. It is no doubt true that the learned senior counsel for the respondents has rightly pointed out that the 12.01.2011 amendment brought about to the User Fee Rules, 2008, makes the position clear that they shall not be applicable, in case bids are invited prior to 12.01.2011. Therefore, the amendment brought about on 12.01.2011 to the User Fee Rules, 2008, will not get attracted to the case on hand as bids were invited and the bid of the petitioner was accepted on 27.11.2010, prior to such an amendment. But however, it is the pre-amended table provided under Rule 4 of the User Fee Rules 2008, which should be rendered applicable to the case of the petitioner.
