Antitrust / Competition

Antitrust / Competition

Hausfeld is one of the leading law firms focused on recovering damages suffered through anti-competitive conduct. We uniquely assist claimants. We pioneered competition damages claims in Europe and accumulated vast experience from managing some of the most high-profile and complex cases ever brought.

We are dedicated to resolving competition disputes and are by far the biggest team in London, Europe and worldwide with specialist capabilities in this field. We believe we have made more recoveries on behalf of claimants than any other firm. 

Our unique platform supports four pillars of expertise:

  1. Cartel damages claims in the High Court and Competition Appeal Tribunal, Court of Appeal and Supreme Court.
  2. Cartel damages claims in the Courts of EU Member States (including the General Court and Court of Justice).
  3. Collective actions in the Competition Appeal Tribunal and High Court.
  4. Complex abuse of dominance claims, state aid disputes, injunctive relief and merger interventions.

Our market leading team trailblazed competition damages actions in Europe and we continue to be known and recognised as innovators in the legal market. Our clients benefit from:

  • The fact we are rarely conflicted and can act against large corporates such as major financial institutions and Big Tech.
  • The team having the expertise and knowledge to go toe-to-toe with some of the world’s biggest law firms.
  • Our experience in taking competition damage claims all the way to trial, on the rare occasion where settlement is not possible.
  • Working with a multi-jurisdictional team, both in terms of language skills and legal qualifications.
  • Our ability to act for individual corporates and structure groups of claimants.
  • Our willingness to offer flexible fee structures and case funding.

Legal directories recognise us as a Tier 1 firm when it comes to ‘Competition: Private Enforcement Claimant’, as does Global Competition Review which counts some of our lawyers among the thought leaders and global elite of competition litigation.
