Who has the authority to hear appeals against the decisions made by the CMA?

The Competition Appeal Tribunal (CAT) has the authority to hear appeals against the decisions made by the Competition and Markets Authority (CMA). The CAT plays a crucial role in the UK's competition regime, specifically dealing with cases related to competition law. It is an independent body that reviews decisions made by the CMA to ensure that they align with legal standards and to consider challenges brought forth by businesses or individuals who may be impacted by those decisions.

The CAT focuses on matters such as appeals regarding market investigations, merger decisions, and other decisions made by the CMA under competition law. This specialized tribunal is equipped to handle complex issues surrounding competition and market behavior, providing a focused avenue for resolving disputes in this area of law.

In contrast, other entities like the High Court and the Office of Fair Trading do not serve this specific appeal function related to CMA decisions. The UK Parliament's role is primarily legislative and not involved in directly hearing appeals against administrative decisions made by the CMA.
