Apple may soon face a class action lawsuit in the Netherlands after a key ruling by the European Union’s highest court. Judges at the Court of Justice of the European Union ruled that Dutch courts are allowed to hear antitrust claims against the tech giant over the way its App Store operates.

The case began when two Dutch consumer foundations filed lawsuits in Amsterdam. They allege that Apple abuses its dominant position in app distribution by charging developers unfair fees to operate on its App Store. According to the foundations, these costs are ultimately passed on to consumers, causing them financial harm.

Apple attempted to block the lawsuit by arguing that courts in the Netherlands did not have the authority to handle the case. However, EU judges rejected this claim. The Luxembourg-based court explained that Apple runs its App Store specifically designed for the Dutch market and also provides its apps in Dutch.

Because of this, the court stated that any financial harm caused by Apple’s App Store purchases can occur within the Netherlands, regardless of where users were physically located at the time of purchase. This reasoning allows Dutch courts to move forward with the antitrust case.

Apple declined to comment on the ruling, and the two Dutch consumer foundations did not immediately respond to the media’s request for a comment. If the case proceeds, it could have significant implications for how Apple operates its App Store in Europe and how large technology companies are regulated in the European Union.
