Apple could be forced to pay up to £1.5bn in damages after losing a collective legal action court case brought on behalf of 36 million UK iPhone and iPad users, both consumers and businesses.
The Competition Appeals Tribunal found that Apple had abused its dominant position by charging "excessive and unfair" prices in the form of the 30% commission, which it usually levies both on app sales and in-app payments.
The claimants argued that this meant that consumers had been overcharged for apps, subscriptions to apps, and when buying digital content in apps.
Apple said it strongly disagreed with the ruling and would appeal.
