Mastercard loses UK ruling on three million dead claimants in €11bn case

Mastercard faces a lawsuit brought by consumer champion Walter Merricks on behalf of approximately 46 million adults in the UK

A spokesperson for Mastercard said: “We will continue to fight it [the case] and are confident that, once the facts are presented in court, the case will be thrown out.” 

Mastercard has lost an appeal in a London court against a ruling in a £10bn (€11.6bn) collective action that allows the claims to continue of around three million people who have died since the lawsuit began. 

The global payments processor is facing a lawsuit brought by consumer champion Walter Merricks on behalf of approximately 46 million adults in the UK, which became the first mass consumer action to be approved in the UK in 2021.
