Major leap forward for UK class actions

Multi-party claims are on the rise. And in a UK-first, last month the Competition Appeal Tribunal (CAT) permitted a massive £14 billion opt-out consumer claim against Mastercard to go forward to trial.
Merricks v Mastercard has attracted nationwide attention as the UK’s biggest mass consumer class action-style litigation. Brought by former Financial Ombudsman Walter Merricks, the claim centres on fees imposed by Mastercard between 1992 and 2008 which it is alleged were passed on to consumers in higher retail prices.
Following an unsuccessful attempt to get the claim off the ground in 2017, Merricks has now secured a collective proceedings order to pursue the case. The collective proceedings regime, a “notable innovation” by the CAT’s own admission, enables businesses and consumers to seek compensation for harm suffered from anti-competitive behaviour. Eligible UK consumers who do not opt out of the claim will automatically qualify for compensation, similar to the US-style class action.
The case is one to watch as the parties now work towards trial and we think will throw up many novel issues along the way. Points of particular interest coming out of the most recent hearing include:
The judgment represents a big step forward for UK consumer group class action-style claims, which are inherently complicated and difficult to run. It is also a crucially important judgment for third party litigation funders in understanding how best to structure their funding agreements to support large-scale litigation. We will watch with interest to see how the case develops, and also whether, and how, the CAT’s collective proceedings regime might provide a template to be rolled out in other tribunals and courts. This case is leading the way in collective proceedings actions and will undoubtedly open the door for other types of complex group claims.
