Apple(s aapl) is not happy with its court-appointed antirust compliance officer. Its law firm, Gibson Dunn, submitted a letter to U.S. District Court Judge Denise Cote on Tuesday, requesting the removal of antirust monitor Michael Bromwich, reports Reuters. Apple claims that Bromwich has a personal bias against the company.

Here’s an excerpt from the letter, which can be read in full at Apple Insider.

His [Bromwich’s] wholly inappropriate declaration in an adversarial proceeding is compounded by his conduct and the circumstances surrounding his appointment and activities, including his reliance on preappointment conversations with the Court and plaintiffs as grounds for expanding his mandate beyond the terms of the Final Judgment, his active collaboration with plaintiffs to broaden the scope of his mandate in this manner and oppose Apple’s motion for stay, his financial demands, and his adversarial, inquisitorial, and prosecutorial communications and activities toward Apple since his appointment.
