The initial fine - equivalent to approximately $587 million - was levied in April after the Commission found Apple’s App Store rules disallowed developers from directing users to cheaper purchasing options outside the platform, in violation of DMA provisions.

In a statement given to MacRumors, Apple said: “Today we filed our appeal because we believe the European Commission's decision - and their unprecedented fine - go far beyond what the law requires.

“As our appeal will show, the EC is mandating how we run our store and forcing business terms which are confusing for developers and bad for users. We implemented this to avoid punitive daily fines and will share the facts with the Court.”

Apple added the company implemented App Store changes to avoid punitive daily fines, and will present its case in court,

In June, Apple introduced a series of App Store policy updates aimed at complying with the DMA and avoiding €50 million daily fines.

These include permitting developers to include external links and implement alternative payment systems.

It was reported that after developers raised concerns, Apple also added a 20 per cent processing fee for in‑App Store transactions alongside limits for external payments.

The European Commission had said in its ruling: “App developers distributing their apps via Apple's ‌App Store‌ should be able to inform customers, free of charge, of alternative offers outside the ‌App Store‌, steer them to those offers and allow them to make purchases.”

The EU General Court will consider Apple’s appeal, weighing whether the Commission exceeded its legal authority.

In the interim, Apple’s updated App Store policies are in effect and under review - but further amendments or sanctions could follow depending on developer feedback and court rulings.
