Tristan Feunteun



Tristan has been involved with both litigating, and funding the litigation of, cartel damages actions for a decade.

Working with clients across the corporate and public sectors, he is experienced in helping to secure multi-million pound recoveries for clients. These clients have suffered serious financial losses, caused by complex and typically multi-jurisdictional instances of corporate wrong-doing perpetrated by their suppliers or competitors.

He has worked on several ground-breaking cases, most recently the iiyama and interchange fees litigation.

  • The iiyama cases, brought by a Japan-headquartered manufacturer against the LCD and CRT cartels, helped expand the territorial scope of purchases that can be included by claimants in such cases before English courts.
  • The interchange fees cases, brought by a variety of British retailers against MasterCard and Visa, helped clarify several of the key building blocks of competition litigation in England, such as disclosure and limitation.

The UK’s Competition & Markets Authority has appointed Tristan a Non-Governmental Advisor to the International Competition Network, where his efforts are focused on the private enforcement of competition law.

England remains the forum of choice in Europe for bringing UK-based and Europe-wide cartel damages actions. Tristan is very happy to speak to corporate and public sector organisations, to help assess and bring their cartel damages actions in England.
