LONDON (AP) – MasterCard is being sued for 14 billion pounds ($18.6 billion) on behalf of British consumers for allegedly charging excessive fees on millions of transactions over a 16-year period.
The law firm filing the suit says the claim is the biggest in British legal history and could bring a payout to 46 million British users of MasterCard credit and debit cards.
The suit alleges that MasterCard charged stores unlawfully high fees on transactions between 1992 and 2008, which were passed on to consumers in the form of inflated prices for goods and services.
“The filing of this claim is the first step towards consumers obtaining compensation for what MasterCard did,” said Walter Merricks said, a former U.K. financial services ombudsman who filed the suit through law firm Quinn Emanuel on Thursday at the Competition Appeal Tribunal.
Merricks callied it “a watershed moment for consumer redress in this country.”
