A year after all 28 European Union Member States implemented the European Commission’s Damages Directive, private antitrust litigation is surging in Europe. For example, the Commission’s trucks cartel decisions – which imposed fines of almost e4 bn – have spawned claims worth over e1 bn filed across Europe, including Germany, Hungary, Ireland, the Netherlands, Spain and the United Kingdom. Collective proceeding orders have been applied for in the trucks matter before the UK’s specialist Competition Appeal Tribunal. In the new environment of highstakes litigation, questions abound as to how collective proceeding mechanisms will function, how courts will deal in general with expert evidence and damage calculations, and how the EU’s antitrust enforcement against Big Tech will translate into litigation in domestic courts. This panel will engage with these issues and, drawing on experience from both sides of the Atlantic, will offer their views about the future path of antitrust litigation in Europe.
