Apple faces UK class action lawsuit for overcharging 20 million users

Apple Inc is facing a London lawsuit over claims it overcharged nearly 20 million U.K. customers for App Store purchases, yet another legal headache for the tech giant fighting lawsuits across the world.

Apple’s 30% standard fee is “excessive” and “unlawful” the claimants said in a press release Tuesday. The claim, filed at London’s Competition Appeal Tribunal on Monday, calls for the U.S. firm to compensate U.K. iPhone and iPad users for years of alleged overcharging.

“Apple is abusing its dominance in the app store market, which in turn impacts U.K. consumers,” Rachael Kent, the lead claimant in the case and a professor at King’s College London. She teaches the ways in which consumers interact and depend upon digital platforms.
