UK app developers filed a £2 billion ($2.7 billion) lawsuit against Apple on Thursday with the Competition Appeal Tribunal. [^1]

The claimants, represented by law firm Hausfeld, allege that Apple's App Tracking Transparency (ATT) system was designed and implemented unfairly and without proper consultation, imposing stricter requirements on third-party app developers than on Apple's own services. [^2]

Law firm Hausfeld brought the claim accusing Apple of giving its own advertising services an unfair advantage by imposing tougher privacy rules on third parties. [^3]

The lawsuit centers on Apple's App Tracking Transparency (ATT) system, introduced in 2021, which requires apps to obtain user consent before tracking activity across other apps and websites. [^4]

According to a statement by law firm Hausfeld, UK app developers were unable to adapt their business models in time to avoid significant losses because of Apple's ATT system. [^5]

Ann Pope, a former official at the Competition and Markets Authority, brought the claim and said the action is important to protect the rights of British businesses that depend on Apple, to ensure that the rules Apple applies are fair, and to compensate the losses British companies have suffered.
