The binding legal principles established are: (1) A decision by the State Tender Board to disqualify a tenderer from future state contracts constitutes 'administrative action' as defined in PAJA, being an exercise of public power under legislation with direct legal consequences. (2) Section 3(2)(b) of PAJA requires that an organ of state give adequate notice of the nature and purpose of proposed administrative action, which must specifically identify the grounds being investigated (such as fraud or bad faith) and the potential consequences (such as disqualification). (3) General references to possible invalidation of tenders or voiding of contracts, or references to contractual provisions, do not constitute adequate notice that fraud or bad faith is being investigated or that disqualification is being contemplated. (4) Under regulation 3(6) of the State Tender Board Act regulations, 'incorrect' information alone does not trigger the power to disqualify; disqualification under regulation 3(5)(a)(iv) requires findings of fraud, bad faith, or other improper conduct. (5) Similarly, under regulation 15 of the Preferential Procurement Policy Framework Act regulations, disqualification powers in subregulation (2)(d) can only be exercised where subregulation (1) is satisfied, requiring either that preference was obtained on a fraudulent basis or that specified goals were not attained in contract performance. (6) Administrative action that is procedurally unfair as contemplated in section 6(2)(c) of PAJA must be set aside under section 8(1).
