All businesses are impacted by antitrust rules to some degree, domestically or internationally or both.

Competition rules and regulations have both public and private law ramifications. Signature assists clients to navigate through this, whether they are the subject of investigation, the victim of anti-competitive conduct or an alleged offender.

We assist clients, whether they are the subject of investigation, the victim of anti-competitive conduct or an alleged offender.
The United Kingdom has one of the most active private antitrust enforcement regimes in the EU. Legislative reforms designed to facilitate private damages claims and enforcement, such as the new opt-out collective action regime, mean the UK is likely to continue to be a forum of choice for private litigants.

The team has worked for a varied client-base, from multinationals to SMEs, based within the UK, in the EU and outside it. Signature is uniquely placed for the following reasons:

  • Signature is able to operate in a conflict free space, and consequently can act for claimants or defendants in antitrust work;
  • Our lawyers have extensive experience in handling class and representative actions;
  • Signature has established links with litigation funders, whose involvement can often be the deciding factor in whether a private law claim will proceed; and
  • As an independent niche firm, we can work with the best competition lawyers in other jurisdictions, through a network of close contacts, to offer a seamless cross-border service.
