The mass provision of goods and services, the proliferation of online delivery channels and the advance of big data make commercial mistakes on an industrial scale ever more likely. Damage to thousands or even millions of people means group litigation is on the rise.
Our team of specialist litigators knows how to develop and pursue group litigation procedures of all types, including group litigation orders, representative actions, test cases, and competition follow-on litigation. We have a particular reputation for winning claims connected with financial products, data issues and regulatory breaches. The size and breadth of our overall litigation practice, allied to the depth of our relationships with funders, brokers and After The Event (ATE) insurers means that we can negotiate and structure funding for even the most complex group action.
Our connections with leading chambers also give us access to the finest procedural minds: a huge benefit to those trying to develop and launch novel and complex claims. Our clients range from retail investors and SMEs, to high net worth individuals and institutions, all of whom for their own reasons appreciate the benefits of litigating as part of a group, often backed by litigation funding and ATE insurance.
