The authors discuss CAT judgements in Le Patourel and Stellantis.
The UK Competition and Appeal Tribunal (CAT) recently issued judgments in several important competition law matters. In this article, authors Anca Cojoc and Nikita Roketskiy highlights two of these judgments, Le Patourel and Stellantis, focusing on the key lessons as they relate to economic evidence. The article discusses:
- Market definition with evolving consumer preferences.
- Allocation of common costs to determine the reasonable profit margin for competitive benchmark calculations.
- Use of competitive benchmarks for damages calculations in the context of alleged unfair pricing.
- Use of behavioural economic evidence in determining the value of a product or service in the context of alleged unfair pricing.
- The need for econometric analyses in litigation to reflect the theory of harm and factual evidence.
