Our competition litigation team’s reputation

Our Competition Litigation department is described by The Legal 500 as a team of “experienced experts who take a highly innovative approach”.


Our specialist expertise

We have advised clients in relation to a wide-ranging number of competition infringements, including interchange feessmart card chipshigh voltage power cablestruckscathode ray tubesliquid crystal displaysDRAMslithium-ion batteries and refrigeration compressors, in addition to acting on various other confidential matters. We also advise clients in relation to conduct that is alleged to be or has been found by a regulator to amount to an abuse of a dominant position.


Our unique competition litigation success

We remain the only law firm in the UK to have successfully acted for a group of claimants at trial and subsequent appeals in a competition damages context. Our recent high-profile successes include securing a landmark victory in the Supreme Court and before then in the Court of Appeal on behalf of major retailers Asda, Morrisons and Argos in relation to their interchange fee claims against MasterCard. The Commercial Court described this as the largest and most complex cartel damages claim conducted in the English courts to date.

We also acted for the successful claimants in the highly publicised cases of iiyama and Vattenfall concerning interlocutory challenges. These are now two of the key competition cases relating to the territorial scope of Article 101 of the Treaty on the Functioning of the European Union and jurisdiction in the English Courts.
