A US court judge has ordered Apple's new iPod and iPhone hardware head to give up his job, whilst his former employer IBM fights the appointment.
IBM claims Mark Papermaster is subject to a one-year non-compete clause in his IBM contract.
The judge hearing the case has agreed that Papermaster could, theoretically, cause "irreparable harm" to IBM whilst the case is ongoing.
Papermaster was only days into his new job when the judge ordered him to leave it until the case is heard.
Papermaster was a driving force in IBM's chip programme. He claims Apple is not a direct competitor to IBM, but the judge has disagreed, and says IBM trade secrets could prove useful to Apple.
For its part, IBM has been forced to hand over a £2m bond to the court, to cover any damages to Papermaster if it loses the case.
