On 9 March 2012, the Competition Appeal Court approved the merger between Wal-Mart Stores Inc and Massmart Holdings Limited subject to conditions, including that the merged entity reinstate 503 employees retrenched in 2009 and June 2010 and take account of their years of service. During 2009 and 2010, prior to the merger, Massmart retrenched 503 employees from Game stores and distribution centres citing operational reasons. The merger was announced on 27 September 2010. SACCAWU intervened in merger proceedings arguing the retrenchments were merger-related. The Tribunal initially approved the merger requiring only preferential re-employment. On appeal, the Competition Appeal Court found a negative inference that retrenchments were merger-specific and ordered reinstatement. After the order, parties disagreed on whether reinstatement included back pay. The Commission opined reinstatement was not retrospective. Massmart reinstated employees without back pay. On 27 March 2019, the Commission confirmed Massmart had complied with conditions. SACCAWU then applied to have the reinstatement order interpreted as requiring back pay from the dates of retrenchment.
The application was dismissed with costs, including costs of two counsel.
The binding legal principle is that a reinstatement order made as a condition of merger approval under the Competition Act does not automatically operate with retrospective effect or entitle reinstated employees to back pay unless the order expressly so provides. The ordinary meaning of 'reinstatement' means putting employees back into their positions on the same terms and conditions, with service resuming from the date of the order, not from the date of dismissal. Retrospectivity is a matter requiring express provision, particularly where the reinstatement is not based on a finding that the dismissals were unlawful or unfair. Where a reinstatement order requires that employees' years of service be taken into account, this recognizes a gap in service between dismissal and reinstatement, inconsistent with full retrospectivity. The interpretation of court orders follows ordinary principles of interpretation, with the court's intention ascertained from the language of the order, and sensible meanings preferred over those leading to insensible results.
The court observed that the three judges who authored the original 2012 judgment serve or served as judges of the Labour Appeal Court and would have known that reinstatement orders in the labour sphere are not retrospective unless expressly specified, making it inconceivable they would have failed to include express provision for retrospectivity if intended. The court noted that the application of section 66(b) of the Competition Act is modeled on Uniform Rule 42(1), and principles developed regarding Rule 42 provide guidance. The court distinguished obiter dicta in National Union of Metalworkers of South Africa obo Fohlisa v Hendor Mining Supplies, noting those remarks stood in contrast to the unanimous decision in Equity Aviation Services, were qualified by reference to 'unlawful' removal, and addressed a different question (the character of back pay as judgment debt versus contractual claim). The court observed there was no evidence the retrenchments were attacked as unlawful or unfair at the time they were made, and the court's inquiry was whether retrenchments were merger-specific for public interest purposes, not whether they violated the LRA.
This case establishes important principles regarding the interpretation of merger conditions relating to employment in South African competition law. It clarifies that reinstatement orders in the competition law context do not automatically carry retrospective effect or entitle employees to back pay unless expressly stated. The judgment confirms that ordinary principles of statutory and contractual interpretation apply to court orders, and that courts should not read into orders terms that were not expressly included. It demonstrates the intersection between competition law merger conditions and labour law remedies, holding that the meaning of 'reinstatement' established in labour law jurisprudence (particularly Equity Aviation Services) applies in the competition law context. The case also illustrates the application of section 66(b) of the Competition Act and the functus officio doctrine, confirming that courts may only clarify orders where there is genuine ambiguity, not where the meaning is clear but one party seeks a different interpretation. It emphasizes that merger-related employment conditions imposed in the public interest do not necessarily import all the remedial consequences that would flow from findings of unfair or unlawful dismissal under the LRA.
