The binding legal principles established are: (1) An organ of state's decision to include specific preferential procurement goals and allocate points for those goals will be rational and lawful where there is a rational connection between the decision and the socio-economic objectives contemplated in section 217(2) of the Constitution, as given effect through the PPPFA and regulations, and as expressed in the organ of state's supply chain management policy. (2) The inclusion of categories such as black youth, black women, and people with disabilities as specific goals in a tender, with weighted points allocation favoring certain categories, is rationally connected to achieving constitutional and legislative objectives where consistent with the organ of state's stated policy objectives. (3) In applications for interim interdicts pending review of procurement processes, harm that can potentially be remedied through successful review proceedings does not constitute irreparable harm. (4) The balance of convenience in procurement matters must take into account practical considerations such as imminent contract expiry dates, the risk of irregular expenditure, and the practical consequences for service delivery.
