NAD Property Income Fund (Pty) Ltd (NAD) concluded a construction agreement with Bushbuckridge Local Municipality (the Municipality) on 16 February 2016 in terms of which NAD undertook to construct three driveway roads and water supply infrastructure for the Dwarsloop Mall. NAD met the costs with the understanding that the Municipality would refund it from future budgets. When the Municipality failed to pay, NAD issued summons for approximately R23.5 million. The Municipality raised defences based on non-compliance with s 217 of the Constitution and ss 111–116 of the Local Government: Municipal Finance Management Act 56 of 2003 (MFMA), lack of authority by the municipal manager, and absence of consensus on price. It also conditionally counterclaimed for an order declaring the agreement unlawful and invalid. The parties agreed to refer the dispute to arbitration before retired Judge President Ngoepe (the Arbitrator). At arbitration, the Arbitrator held that he was empowered to determine the constitutional validity of the agreement and declared it invalid, unlawful and unenforceable for non-compliance with the constitutional and statutory procurement framework. He also declared that NAD had failed to make out a case for unjustified enrichment in respect of two roads, but that the Municipality had been unduly enriched in respect of one road. NAD then applied to the Mpumalanga Division of the High Court to review and set aside the arbitration award on the basis that the Arbitrator had exceeded his powers. The high court dismissed the application, holding that the arbitration agreement conferred the necessary power on the Arbitrator. NAD appealed to the Supreme Court of Appeal with leave.
