In South African employment law, the principle of double jeopardy, i.e. whether an employee may be disciplined twice for the same misconduct, has remained a complex and evolving area. While the Labour Relations Act 66 of 1995 (“LRA”) does not expressly forbid multiple disciplinary actions for the same conduct, our courts have consistently held that fairness is the ultimate test. A recent Labour Appeal Court (LAC) decision has clarified the boundaries of this principle, especially in the context where an arbitrator has already imposed a disciplinary sanction.
Double Jeopardy in South African Labour Law
Unlike criminal law, where doctrines like autrefois acquit or res judicata strictly bar repeated prosecution, labour law treats double jeopardy as a matter of fairness, not formality. Case law such as BMW (SA) (Pty) Ltd v Van der Walt (2000) 21 ILJ 113 (LAC) and Branford v Metrorail (2003) 24 ILJ 2269 (LAC) confirms that employers are not automatically precluded from revisiting disciplinary decisions. However, they may only do so where new facts emerge, or earlier processes were materially flawed, and where such a step would be fair. Yet, where a final and binding arbitration award has already addressed specific misconduct and imposed a sanction, the principle of finality comes into sharp focus.
Case Study
In SAMWU obo Malatsi v SALGBC and Others JA64/23 (delivered 30 September 2025), the Labour Appeal Court was faced with precisely this issue. An employee in the public sector was dismissed in 2013 following an investigation into unauthorised attempts to access the employer’s online banking system from his workstation. Although the forensic investigation could not conclusively prove that the employee personally attempted the access, he was found to have negligently failed to protect his computer password.
During arbitration, it was revealed that password sharing and storing passwords on desk calendars was a widespread practice within the department. The arbitrator acquitted the employee of dishonesty but imposed a sanction of unpaid suspension for four months, effectively a penalty for his negligence in safeguarding access credentials. The award was implemented, and the employee was reinstated. Two weeks later, however, the employer instituted a second disciplinary process, charging the employee again, but this time with gross dishonesty and non-compliance with IT protocols. The result was another dismissal. Despite the employee’s argument that the second disciplinary hearing constituted double jeopardy, both the second arbitrator and the Labour Court initially upheld the employer’s actions, reasoning that the new charges were based on distinct allegations. The matter was then taken to the Labour Appeal Court
The Labour Appeal Court disagreed with the earlier findings. It held that the first arbitrator’s award had clearly imposed a disciplinary sanction for password-related misconduct, and this award, being final and binding in terms of section 143 of the LRA, precluded any further disciplinary action on the same facts. The court found that while the employer may have been dissatisfied with how the arbitrator characterised or interpreted the charges, the proper course of action would have been to review and challenge the award, not to initiate a fresh disciplinary process. The second dismissal was therefore declared substantively unfair, and the employee was reinstated with retrospective effect to the date of the second dismissal in 2016
Lessons for Employers
The judgment by the Labour Appeal Court confirms an important boundary in workplace discipline: once an arbitrator has made a finding and imposed a sanction for particular misconduct, and the employer does not challenge that outcome on review, the matter is final. An employer cannot simply repackage the same facts into new charges and initiate a second process in the hope of a more favourable outcome. While the principle of double jeopardy in labour law is not absolute, employers must tread carefully. Exceptions may exist – for example, where material new facts emerge that were not available during the initial process. But where the facts, context, and conduct are substantially the same, and where an arbitrator has already imposed a binding disciplinary sanction, the path forward must be legal review, not disciplinary repetition
Conclusion
The case of SAMWU obo Malatsi v SALGBC and Others serves as a cautionary tale – i.e. that arbitration outcomes carry real legal weight, and employers must respect the finality of those awards. The notion of fairness underpins all disciplinary processes, and fairness cuts both ways. A second disciplinary hearing is not a tool to circumvent an unfavourable outcome, but an exception that must be clearly justified. Employers who attempt to re-discipline employees without a sound and fair basis risk costly reinstatement orders, reputational harm, and the erosion of procedural integrity.
