A US district judge has found Apple wilfully violated her injunction in a case brought by Epic Games - and that a top Apple executive “outright lied” under oath.

The injunction was supposed to block Apple from anti-competitive conduct and pricing, opening the App Store up to outside payment options.

Judge Yvonne Gonzalez Rogers said she was referring the matter to the US Attorney for Northern District of California to investigate whether a criminal contempt proceeding is appropriate.
