Apple is facing a major new legal challenge in the UK over its App Tracking Transparency (ATT) framework, this time filed by a former senior official of the country’s Competition and Markets Authority (CMA). The case, brought before the London Competition Appeal Tribunal, claims Apple’s ATT rules unfairly favor its own control over privacy permissions while penalizing third-party developers—seeking approximately £2 billion (around $2.7 billion) in damages.
What’s New: Who’s Bringing the Case
The litigation is led by Ann Pope, one of the CMA’s former senior executives. Pope asserts that Apple, by serving as a “gatekeeper” in the iOS app ecosystem, has imposed restrictive practices on outside developers through ATT, causing “very significant harm” to the UK businesses relying on Apple’s platform.
What the Dispute Is About
Introduced by Apple to give users explicit choice over whether apps can track them for personalized advertising, ATT requires developers to request user permission for tracking—a move widely seen as a boost for user privacy. But Apple’s own apps reportedly do not display ATT permission prompts, which has drawn criticism. Apple maintains its internal apps don’t meet the criteria for prompting under its own rules. Third-party apps that also don’t collect tracking data are likewise exempted from displaying the prompt.
This marks the third legal action tied to ATT in the UK. Two prior complaints have already been filed with the CMA; Apple lost the first and is appealing, while the second remains unresolved. The latest lawsuit, brought by Ann Pope, adds a new dynamic by challenging not only ATT’s substance, but the fairness of Apple’s implementation in relation to how it treats its own products versus third-party developers.
Alongside this action in the UK, Apple has recently accepted adjustments to its ATT rules in the EU. Following a German antitrust regulator’s investigation, the company agreed to implement eight changes to align with regulatory expectations.
What this means: This case could reshape how digital gatekeepers are allowed to impose privacy policies that affect competition. If courts find Apple’s ATT implementation discriminatory, developers may win compensation or force changes in the ATT regime.
Why it matters: Apple has long positioned ATT as a crown jewel of its privacy branding, distinguishing itself in a market where user data sharing and tracking are under heavy scrutiny. But—even as consumers broadly support stronger privacy—regulators and developers are increasingly scrutinizing whether Apple’s model gives itself unfair advantage in enforcing rules that others must follow.
What to watch: how the tribunal rules on the distinction between Apple’s own apps versus third-party apps under ATT; whether damages are awarded; and whether this lawsuit accelerates regulatory changes in other regions beyond the UK and EU.
