We are one of the UK’s leading competition practices. Our clients include global corporations and FTSE 100 and FTSE 250 companies.
Who we represent
We act on behalf of major enterprises on all aspects of competition litigation for claimants and defendants, specialising in claims relating to cartels or abuse of a dominant position. Our clients’ claims are often connected to regulatory decisions made by US, EU, UK and other national competition authorities. We advise clients by evaluating the benefits of taking action or defending claims brought or threatened against them.
Our successful record
Our team has cutting-edge expertise in this rapidly developing field. We have an impressive track record of successfully taking cases to trial in the High Court, Court of Appeal and Supreme Court. We remain the only law firm to have successfully acted for a group of claimants at trial and subsequent appeals in a competition damages context.
Innovative cost arrangements
Our lawyers have unparalleled experience in putting together innovative costs arrangements. The use of third party funding, after-the-event insurance and risk-sharing fee agreements enables our clients to effectively manage risk and litigate from a position of financial strength.
Our international strategic alliances
Most anti-competitive activity takes place on an international scale, so we have developed strategic alliances with handpicked law firms around the world to enable our clients to take a cross-border approach to litigation, where necessary. We frequently act on a global counsel basis to coordinate damages recoveries in multiple jurisdictions.
