Apple has appealed the European Commission’s decision to fine the iPhone maker €500 million for breaking the EU’s competition rules for Big Tech, a company spokesperson said Monday.

In April, the EU executive fined Apple for breaching the Digital Markets Act (DMA) over its rules governing how app developers can communicate with their customers.

The Commission’s requests “go far beyond what the law requires,” said Apple spokesperson Emma Wilson in a statement confirming that the company has lodged an appeal.

Apple argues the Commission is “mandating how we run our store and forcing business terms which are confusing for developers and bad for users.”

The appeal focuses on two key areas: the Commission’s alleged forced tiering of service offerings and an “unlawful” expansion of the DMA’s definition of “steering.”

Apple contends that the EU executive’s broadened definition of steering now includes in-app promotions and alternative payment services, and demands for links to competing app marketplaces, which Apple believes fundamentally alters the law’s original intent.

This appeal follows Apple’s June 26 announcement of changes to its App Store rules in the EU in an effort to comply with the EC’s cease-and-desist order.

The Commission is currently assessing whether or not those changes are sufficient to be in compliance with the April decision, and could resort to daily fines should they fall short.
