Impala Water Users Association v Piet Erasmus Lourens N.O. and 20 Other Applicants

The appellant was formerly known as the Impala Water Irrigation Board and was declared a water user association on 12 January 2001 under the National Water Act 36 of 1998. The respondents are 21 farmers who cultivate sugar cane and were all formerly members and water users of the appellant when it was an irrigation board. They had obtained registration for irrigation under the previous Water Act 54 of 1956 and automatically became members of the water user association. A dispute arose regarding the legality of a portion of the water charge assessed by the appellant. The appellant sought to recover R800 per hectare per annum as a dam financing component, while the respondents contended they were only obliged to pay R240 per hectare per annum. The appellant initially sued some respondents in the magistrate's court and later in the High Court. Before the actions were heard, on 1 February 2003, the appellant exercised powers under section 59(3)(b) of the Act and restricted water flow to the respondents by locking the sluices. The respondents brought a spoliation application the following day, which was granted on 14 February 2003.

• Whether the respondents' rights to water were capable of protection by the mandament van spolie
• Whether the rights in question were merely contractual personal rights or enforceable water use rights
• Whether the appellant's actions in restricting water supply fell within the statutory powers under section 59(3)(b) of the National Water Act 36 of 1998
• Who bears the onus of proving that water use charges were legally payable when a water supplier restricts supply in purported exercise of statutory powers
• Whether the appellant was entitled to restrict water supply where the enforceability of the charges was disputed and subject to pending litigation

The appeal was dismissed with costs, including costs of two counsel.

The binding legal principles established are: (1) Registered water use rights under the Water Act 54 of 1956, which were subsumed into the National Water Act 36 of 1998, constitute rights capable of protection by the mandament van spolie and are not merely personal contractual rights; (2) When a water supplier purports to exercise statutory powers under section 59(3)(b) of the National Water Act 36 of 1998 to restrict water supply for non-payment of charges, the onus rests on the supplier to prove that the charges are legally payable; (3) Section 59(3) of the National Water Act can only be invoked when the water use charge in question is legally and undisputedly payable; (4) A person who disturbs another's possession without recourse to law in purported exercise of a statutory power bears the onus of showing that their actions were covered by the statute relied upon; and (5) The fundamental principle that persons may not take the law into their own hands, reinforced by section 34 of the Constitution, applies to the exercise of statutory powers to restrict essential services like water supply.

The Court made several non-binding observations: (1) The procedure set forth in section 59(4) of the National Water Act (providing opportunity to make representations before restriction) is not intended as a hearing on liability at which the water user must satisfy the supplier that nothing is owed - liability must be either admitted or judicially established, and the hearing is premised on the charge being unquestionably due; (2) The statement by De Villiers ACJ in Sillo v Naude regarding an applicant's burden to show unlawfulness was obiter dicta in that case; (3) The considerations supporting the allocation of onus in spoliation cases involving statutory powers are buttressed by the constitutional right of access to courts in section 34 of the Constitution; and (4) The Court noted that counsel for the appellant did not seek to persuade the Court that the George Municipality decision was clearly wrong on the onus point, and the Court expressed satisfaction that it was correct.

This case is significant in South African water law and spoliation jurisprudence for several reasons: (1) It clarifies that registered water use rights under the Water Acts are capable of protection by the mandament van spolie and are not merely personal contractual rights; (2) It confirms that statutory powers to restrict water supply can only be exercised when charges are legally and undisputedly payable; (3) It reinforces the principle from George Municipality v Vena that a person who disturbs another's possession in purported exercise of statutory powers bears the onus of proving the lawfulness of their actions; (4) It emphasizes that self-help remedies, even when seemingly authorized by statute, must be strictly confined and cannot be used where the underlying debt is disputed; (5) It demonstrates the application of constitutional rights (section 34 - access to courts) to administrative and water law disputes; and (6) It confirms the continued relevance of Bon Quelle regarding quasi-possession of rights in the context of modern water legislation.
