Lawyers for former newspaper titan Conrad Black appealed his case Friday, saying there was not adequate evidence he hid documents or defrauded anyone, the Associated Press reported.

A federal Jury convicted Black last July of three counts of fraud and one count of obstruction, but acquitted him on nine charges.

A 100-page appeals brief filed with the court stated that “four counts of conviction are left for his appeal, each vainly searching for a theory of criminality,” according to the AP.

Black was accused of funnelling millions of shareholder dollars from his Hollinger International newspaper company through non-compete payments.
