Constitutional Court Confirms Competition Commission Jurisdiction Over International Cartels

Brought to you by SA Legal Academy: In terms of the Competition Act, No. 89 of 1998, the Competition Commission has highlighted the significant legal and procedural implications of a Constitutional Court ruling handed down on 30 June 2026, which confirms that South African competition authorities possess jurisdiction to prosecute international and cross-border cartels.

The Constitutional Court’s decision clarifies the extraterritorial reach of the Act, specifically regarding cartel conduct initiated outside South Africa but having a direct, foreseeable, and substantial effect within the domestic market. This ruling solidifies the Commission’s mandate to investigate and refer foreign-based firms participating in global cartels that impact local supply chains, pricing, and consumer choice.

Key aspects confirmed by the ruling and highlighted by the Commission include:

  • Extraterritorial Jurisdiction: South African competition authorities have the legal authority to prosecute firms operating outside the borders of the Republic if their anti-competitive conduct has an effect within South Africa.
  • Procedural Validity: The ruling establishes clear precedents for serving processes and initiating complaints against foreign entities under the Act.
  • Cross-Border Enforcement: The decision strengthens the Commission’s capacity to collaborate with international antitrust regulators to combat global price-fixing, market allocation, and collusive tendering.

What this means for you, your business, or your clients

  • For yourself: No direct individual compliance obligations; however, legal and compliance professionals must update their regulatory risk registers to reflect the confirmed extraterritorial reach of South African competition law.
  • For your business: Multinational firms operating in South Africa must review their global distribution, pricing, and joint venture agreements to ensure they do not inadvertently fall foul of the Competition Act, No. 89 of 1998, given the confirmed jurisdiction of local authorities over offshore conduct.
  • For your clients: Advise corporate clients involved in international trade or supply chains that foreign-based anti-competitive behavior affecting the South African market can now be directly prosecuted by the Competition Commission, increasing the risk of local administrative penalties.
