Apple has proposed a new commission structure for purchases made through external links within apps on its iOS devices, after the U.S. Supreme Court rejected the company’s attempt to delay proceedings in its long-running legal dispute with Epic Games.

In a new filing with the United States District Court for the Northern District of California, Apple proposed a 15 per cent commission for standard apps, with lower rates for developers participating in certain Apple programmes.

Under the proposed structure, developers classified as small businesses would pay a 5 per cent commission, while participants in Apple’s Video Partner Program, News Partner Program and Mini Apps Partner Program would pay 10 per cent.

Apple also proposed reducing the commission on subscription renewals to 10 per cent, according to the filing.

The proposed rates come amid a years-long legal battle between Apple and Epic Games over the iPhone maker’s App Store policies and commission practices.

Apple had sought to delay the lower-court proceedings, arguing that they should be put on hold until the Supreme Court ruled on whether the company had violated a court order by imposing a 27 per cent commission on purchases made through external links.

The company had also introduced restrictions on how developers could direct users to external payment options.

However, the Supreme Court on Thursday rejected Apple’s request to pause the lower-court proceedings, requiring the company to disclose its proposed commission structure.

The latest filing represents Apple’s response to the court’s request for details of the to commissions it intends to charge on external-link transactions.
