"Evidently, G.O.Ms.No.92 Transport, Road and Buildings (B.I) Department dated 19.05.1998 is issued by the Government permitting the Executive Engineers to conclude the supplementai agreements with the contractors for works under execution and to be entrusted in future basing on the request of Builders Association of India to deduct O.25o/o of the gross amount of bi1ls and to remit the same to the Academy. The Engineer-in-Chief, in unequivocal words admitted that neither the deduction ol O.25o/o from the gross bi1ls nor incorporation of such a clause in the agreement, is traceable to any provision of law and such a deduction cannot be made part of the contract. In such circumstances, when the Government has no power or authority, the impugned G.O. cannot sustain. The contention of the learned counsel for the Academy i.e., the impleaded respondent that having agreed for such deduction, are now estopped from contending that such a deduction is not legal, cannot be countenanced for more than one reason. Firstly, as observed earlier such a deduction is not traceable to any law for the time being in force and secondly perhaps the members of the Academy might have agreed for such a resolution to avoid confrontation with the Association. Therefore, this by itself does not take away the rights of the petitioners to challenge the impugned order, more particularly when the said G.O., is issued without any statutory authority.
