The binding legal principles established are: (1) A governmental entity cannot rely on alleged non-compliance with budgetary provisions of the PFMA to avoid paying for work performed and services rendered under a contract it has concluded and from which it has received and retained benefits. (2) Where government has appropriated funds for a programme, concluded contracts for that programme, and received the benefit of work performed under those contracts, it cannot subsequently claim that the contracts were void for lack of budgetary allocation. (3) Even if expenditure under a government contract exceeds appropriated funds, this constitutes unauthorised expenditure under the PFMA which, by operation of section 34(2), becomes a charge against funds allocated in the next or future financial years - it does not render the contract void or unenforceable. (4) Where a governmental entity has approved the appointment of a sub-contractor, received the benefit of that sub-contractor's services, and undertaken in the main contract to pay the sub-contractor's fees in addition to the main contractor's fees, the entity cannot rely on lack of contractual privity to avoid payment, particularly where all interested parties are before the court and the main contractor does not oppose direct payment to the sub-contractor. (5) Government must act with integrity, transparency and accountability in its contractual dealings as required by the Constitution, and cannot employ disingenuous, evasive or contrived defences to avoid meeting its lawful obligations. (6) Technical defences will not be permitted to defeat substantive justice where government has received and retained benefits from work performed in good faith under contracts it approved.
