The 2nd U.S. Circuit Court of Appeals in Manhattan ruled against Apple Inc. Thursday. The three-judge panel concluded that a judge did not act improperly when she declined Apple's request to disqualify a monitor she had appointed to evaluate Apple's antitrust policies.
A lawyer for Apple, based in Cupertino, California, did not immediately respond to a request for comment.
The 2nd Circuit did not yet rule on a separate appeal in which Apple is challenging the judge's finding that it colluded with publishers.
After a 2013 civil trial, a judge ordered the technology giant to modify contracts with publishers to prevent price fixing.
