A party may retain profits derived from an unlawful contract: a look at the ‘no loss, but no gain’ principle

The Labour Court, in Rotunda Proprietary Limited v Sam, considered whether a former employee who breached a restraint of trade that had been made an order of court was guilty of contempt of court in circumstances where the underlying restraint of trade had, by effluxion of time, expired.

On 28 November 2025, the Supreme Court of Appeal (“SCA”) handed down judgment in Tekoa Consulting Engineers (Pty) Ltd v Alfred Nzo District Municipality [2025] ZASCA 180, declaring tender documents unlawful for vagueness, despite the work already having been completed.

On 29 May 2026, the Constitutional Court in NUMSA and Others v Industrial Oleo Chemical Products [2026] ZACC [22] clarified that, in a facilitated largescale retrenchment, it is not necessary to first refer a dispute to conciliation before approaching the Labour Court to challenge the substantive fairness of the dismissal. The judgment brings certainty in relation to section 189A(7) of the Labour Relations Act (“LRA”), following a line of conflicting judgments in the Labour and Labour Appeal Courts.

The Labour Appeal Court, in Mondi South Africa v CEPPWAWU (DA25/24) [2026] ZALAC 20 (6 May 2026), upheld the reinstatement of employees dismissed for carrying weapons during a protected strike, finding that the arbitrator’s decision to impose a sanction less than dismissal fell within the range of reasonable decisions under the circumstances.
