Abuse of dominance
Competition-law conduct where a dominant firm may use market power in a way prohibited by the Competition Act.
Definition
Abuse of dominance questions are fact- and market-specific. The practical review should identify the product or service market, competitors, customers, pricing, exclusionary conduct, refusal to supply, bundling, evidence of dominance, commercial justification, complaint history, and whether the issue belongs before the Competition Commission, Competition Tribunal, or another route.
In a South African legal context, abuse of dominance should not be treated as an isolated dictionary word. It usually sits inside a broader competition law process, and that process can affect what documents are needed, which deadlines matter, and what next step is sensible.
