Conrad Black has lost an appeal of his remaining convictions on fraud and obstruction of justice.

The federal appeals court in Chicago said Friday that it has rejected a request by the former media tycoon for a full-court review of his case.

In October, a three-judge panel of the court upheld two of Black’s convictions related to defrauding Hollinger International Inc., the one-time parent of dozens of newspapers, including the Chicago Sun-Times. The panel also overturned two of Black’s fraud convictions.

For Black to win a new hearing, a majority of the appellate court would have had to vote to hear the case in what is known as an “en banc” review. Such reviews are rarely granted.
