Residents of the Ngwathe Local Municipality experienced ongoing supply of unsafe, foul-smelling drinking water that allegedly caused illness. AfriForum NPC, a civil society organisation, commissioned accredited laboratory tests which revealed excessive levels of coliforms and E. coli in contravention of SANS 241:2015 potable water standards. After unsuccessful attempts to resolve the matter with the local and district municipalities, AfriForum launched an urgent application in the Free State High Court seeking to compel the municipalities and the Minister of Water and Sanitation to fulfil their constitutional and statutory duties to provide safe drinking water, including by means of a structural interdict. The High Court removed the matter from the urgent roll and ordered AfriForum to pay wasted costs. AfriForum appealed only the costs order. The Full Court set aside the punitive costs order but directed that each party pay its own costs. AfriForum then appealed to the Supreme Court of Appeal, challenging the Full Court’s departure from the general costs rule and the Biowatch principle.
