The binding legal principle established is that in public procurement processes, bidders must be treated equally throughout the evaluation process. A Bid Evaluation Committee's conduct that involves revisiting and changing the score of one bidder's functionality test after initial evaluation, without applying the same scrutiny to other bidders, constitutes differential treatment that renders the evaluation procedurally unfair. Such differential treatment violates the constitutional requirements of equity, transparency and objectivity mandated by section 217 of the Constitution, and renders the tender award decision invalid under section 6(2)(i) of PAJA. Even in the absence of corruption, a consensus-seeking approach that results in unequal treatment of bidders falls short of the required legal standard and taints the entire procurement process.
