Apple filed a lawsuit with the EU General Court on 7 July, seeking to annul the European Commission’s €500 million ($587 million) penalty for alleged breaches of the bloc’s Digital Markets Act. The Cupertino-based company calls the sanction “unprecedented” and says the Commission’s orders on how it must run its App Store are “unlawful.” Brussels imposed the fine in April after finding that Apple’s technical and commercial rules prevented iOS developers from steering customers toward cheaper payment options outside the App Store. Under the DMA, such ‘anti-steering’ practices are prohibited for so-called gatekeeper platforms. Unless overturned, Apple also faces potential daily penalties of up to 5 percent of its worldwide revenue—about €50 million—if it fails to comply. To avert those daily fines, Apple overhauled its European App Store policies in late June, introducing a two-tier commission system ranging from 5 percent to 13 percent and allowing more prominent linking to outside payment methods. In its court filing, the company argues the Commission expanded the legal definition of steering and imposed business terms that confuse developers and harm users. The Commission said it will defend its decision, setting up a multi-year legal battle with significant implications for how large tech platforms operate in Europe.
