Despite losing a previous appeal, Apple has now applied to the UK's Court of Appeal over "guesswork" that means it is being fined $2 billion for App Store practices.

In November 2025, the UK's Competition Appeals Tribunal (CAT) refused to grant Apple an appeal against CAT's own order that it pay $2 billion to allegedly overcharged App Store users. According to The Guardian newspaper, Apple has now taken its next step, which is to apply to the UK's separate Court of Appeal.

The case was originally brought against Apple by Dr Rachael Kent, who has now said that winning in October 2025 still felt "a bit pinch me."

"It's definitely a tipping point," she said. "People are pushing back against the harms from digital worlds, which they have to be living in and through every day and the financial implications of that."

While Apple has not commented further, it previously presented 33 points of disagreement. Central to those was Apple's argument that CAT's judgement over what App Store fees should be was flawed.

Specifically, Apple called out how CAT stated that it had used "informed guesswork" to determine what a fair fee would be. This will presumably be the case it makes to the Court of Appeal, although Apple has not issued any statement since its original response to CAT's ruling.

We thank the tribunal for its consideration but strongly disagree with this ruling, which takes a flawed view of the thriving and competitive app economy. The App Store has benefited businesses and consumers across the U.K., creating a dynamic marketplace where developers compete and users can choose from millions of innovative apps. This ruling overlooks how the App Store helps developers succeed and gives consumers a safe, trusted place to discover apps and securely make payments. The App Store faces vigorous competition from many other platforms — often with far fewer privacy and security protections — giving developers and consumers many options in how they build, share, and download apps. We intend to appeal.

What happens next

It appears that the formal filing has now been made, but there are no further details and no new comments from Apple. Once the CAT refused to reconsider its judgement, though, Apple supposedly had 21 days in which to file with the Court of Appeal.

That meant, depending on when Apple was presented with CAT's written judgement, the company had until December 4, 2025, or December 5. It's not known what has caused or allowed a delay.

As yet, there is no mention of the appeal on the Court's official records. Consequently, there is also no publicly available schedule for when the next hearing may take place.
