Where a bidder submits a B-BBEE sworn affidavit in support of a tender, the affidavit must reflect the true B-BBEE status of the measured entity at the relevant time (either at the closing date for tenders or at the time preference points are awarded). An affidavit based on outdated financial information that is two financial years old, which fails to identify the source of the financial information, and which has ambiguous commissioning dates, does not fulfil the purpose of providing assurance of B-BBEE compliance. Awarding B-BBEE preference points on the strength of such a defective affidavit constitutes a material irregularity that renders the decision unlawful and reviewable under PAJA sections 2(b), 2(e)(iii), and 2(i). In procurement matters, procedural requirements must be evaluated on their own merits and not through the lens of the final outcome; the fairness of the process and the optimality of the outcome cannot be severed.
