24. The controversy in this case has arisen at the threshold. It cannot be disputed that this is an international competitive bidding which postulates keen competition and high efficiency. The bidders have or should have assistance of technical experts. The degree of care required in such a bidding is greater than in ordinary local bids for small works. It is essential to maintain the sanctity and integrity of process of tender/bid and also award of a contract. The appellant, Respondents 1 to 4 and Respondents 10 and 11 are all bound by the ITB which should be complied with scrupulously. In a work of this nature and magnitude where bidders who fulfil prequalification alone are invited to bid, adherence to the instructions cannot be given a goby by branding it as a pedantic approach, otherwise it will encourage and provide scope for discrimination, arbitrariness and favouritism which are totally opposed to the rule of law and our constitutional values. The very purpose of issuing rules/instructions is to ensure their enforcement lest the rule of law should be a casualty. Relaxation or waiver of a rule or condition, unless so provided under the ITB, by the State or its agencies (the appellant) in favour of one bidder would create justifiable doubts in the minds of other bidders, would impair the rule of transparency and fairness and provide room for manipulation to suit the whims of the State agencies in picking and choosing a bidder for awarding contracts as in the case of distributing bounty or charity. In our view such approach should always be avoided. Where power to relax or waive a rule or a condition exists under the rules, it has to be done strictly in compliance with the rules. We have, therefore, no hesitation in concluding that adherence to the ITB or rules is the best principle to be followed, which is also in the best public interest.”
