The appellant (previous owner) instituted action to declare null and void a sale in execution of immovable property. The property was sold at a sale in execution pursuant to a magistrate's judgment obtained by a local authority (municipality) against the appellant as registered owner. The first respondent, a close corporation, purchased the property at the sale and transfer was effected. At the time of the sale, the second respondent (second defendant), a member of the close corporation, was a councillor in the municipality. The appellant argued that the sale contravened s 40 of the Gauteng Local Government Ordinance 17 of 1939, which prohibits municipal councillors from entering into contracts with the council in which they have a pecuniary interest and declares such contracts null and void. The conditions of sale contained clauses 5 to 9 which allegedly vested various rights in the municipality, including obligations on the purchaser to pay transfer costs, assume liability for outstanding municipal debts, provide guarantees, and appointment of the conveyancer by the municipality. The matter was adjudicated on a stated case in terms of rule 33 of the Uniform Rules.
