The US Supreme Court will not review a legal dispute between Apple and Epic Games over the App Store, one of a pair of cases the Fortnite maker brought to try to break up what it has alleged were monopoly practices in popular platforms for apps.

The decision by the justices not to hear the appeal will leave intact a lower-court ruling that rejected Epic’s claims that Apple had broken federal antitrust law with policies in its App Store that extracted high costs from developers while giving them few options to push back.

It will also leave in place an injunction issued by the lower court forcing Apple to make tweaks to its App Store terms to allow developers to direct users outside of their apps to make payments, however. The lower court had found the prohibition against doing so violated California law.
