Supreme Court of the United States. rejected Epic's requestthe publisher of Fortnite, for Apple to relax the rules of the App Store.
Justice Elena Kagan refused to overturn a stay of a lower court's order on Apple's rules limiting how iOS app developers can direct users to other payment methods.
Kagan did not elaborate on his decision, but Epic's request was denied.
The district court's order is one of Epic's few victories in a high-profile antitrust case over commissions on in-app purchases in the App Store.
A judge ruled that Apple violated California's unfair competition law by preventing developers from using links to direct users to payment methods outside the App Store.
But the Ninth Circuit Court of Appeals ordered that part of the decision stayed in July, giving Apple 90 days to ask the Supreme Court whether its appeal would be accepted.
Epic asked the Supreme Court to overturn the Ninth Circuit Court of Appeals' ruling, saying it would “harm not only Epic, but countless consumers and other app developers for a long period of time”.
Moving payments outside of the App Store system allows developers to avoid Apple's commission, which applies to digital purchases such as Fortnite paVos.
However, Apple has reserved the right to charge a separate fee if developers widely adopt this practice.It did just that last year when Dutch regulators demanded it open up payment methods for dating apps.
