Court blocks £14 billion British class action against MasterCard

21st Jul 2017

The Competition Appeal Tribunal (CAT) rejected class proceedings over a case Reuters says “would have been the largest and most complex in British legal history.”

One lawyer called the case the “perfect exam question” for the CAT, which was created in 2015 to oversee the introduction of “opt-out” collective actions. The Tribunal said the claims against MasterCard- that it had, for a period of 16 years overcharged its customers- would be too difficult to prove. It added that calculating individual losses for so many consumers would have been problematic.

MasterCard said the claim was “completely unsuitable.”
