Conrad Black's sentencing hearing on his convictions for mail fraud and obstruction of justice will be delayed 10 days, as a U.S. federal judge on Thursday granted Black's request for a postponement.

Originally slated for Nov. 30, sentencing for the former head of the Hollinger newspaper empire will now take place Dec. 10 in Chicago.

Black's attorney, Jeffrey Steinback, had asked U.S. District Court Judge Amy St. Eve for a "short extension" to prepare a reply to a prosecution pre-sentencing hearing report.

"I can accommodate that week," St. Eve said, according to a report.

Black and his co-defendants — Mark Kipnis, John Boultbee and Peter Atkinson — were convicted July 13 by a Chicago jury on three charges each of mail fraud.

Black was also convicted on one count of obstruction of justice for removing boxes of documents from his Toronto office.

Black, Boultbee and Atkinson were found to have improperly pocketed millions of dollars in non-compete fees that prosecutors said should have gone to shareholders of Hollinger International. Prosecutors said Kipnis facilitated the diversions.

The Montreal-born Black, 63, faces the possibility of up to 35 years in prison. Prosecutors have said that Black's convictions warrant a sentence of at least 15 years.

On Nov. 5, St. Eve ruled against Black's request for a new trial. She wrote there was "more than enough evidence" to support the convictions against Black and his co-defendants. She did, however, quash one of the mail fraud convictions against Mark Kipnis.
