Back in 2021, a federal judge in Epic Games v. Apple decided that the iPhone maker would have to allow app makers to point consumers beyond Apple’s closed App Store to make payments. The idea was that app makers would no longer exclusively have to pay the 30% cut of purchases made within their apps simply for being included in the App Store.

In response, Apple let developers point users to their own websites for purchases, but still collected a commission of 27% on those purchases.

Yesterday, that same judge, Yvonne Gonzalez Rogers, told Apple it had disregarded her court’s ruling and said Apple could no longer collect commissions on off-app purchases, nor could it decide how developers direct people to their sites in the first place.

“Apple sought to maintain a revenue stream worth billions in direct defiance of this Court’s Injunction,” she wrote in the ruling. The judge also referred the matter to a US attorney to investigate whether there should be criminal proceedings as well.

“This is an injunction, not a negotiation,” Gonzalez Rogers added. “There are no do-overs once a party willfully disregards a court order. Time is of the essence. The Court will not tolerate further delays.”

The stock is down 1.5% premarket.
