The binding legal principles established are: (1) Leave to appeal under section 17 of the Superior Courts Act requires a measure of certainty that another court would reach a different conclusion, representing a higher threshold than previously; (2) Dismissals for collective misconduct require proof of individual complicity - mere presence at the scene of violence is insufficient to establish guilt; (3) South African law recognizes no concept of collective guilt; (4) The fairness of a dismissal must be assessed based on the employer's decision at the time of dismissal, with that decision as the starting point for review, not a blank canvas; (5) Evidence identifying individual wrongdoing must be presented at the disciplinary hearing stage - it cannot be deferred to arbitration as a 'second bite at the cherry'; (6) The principles of natural justice, particularly audi alteram partem, are fundamental to procedurally and substantively fair dismissals; (7) Employers must ameliorate evidentiary difficulties using available modern technology (such as CCTV footage) and cannot rely on absence of identification to justify collective dismissals.
