Vladimir Novosyolov, who headed the Novosibirsk Region's forensic medical examination bureau in Siberia, was found guilty on charges of abusing his position and given a $1,200 fine in June 2005.
"We will send the appeal in January 2008," his lawyer Mikhail Kurilov said on Wednesday.
Novosyolov was charged in 2001 with smuggling 51 bodies to Dr von Hagens, the inventor of the plastination technique for conserving bodies, and the organizer of controversial Body Worlds exhibitions of preserved corpses.
The professor had appealed against the verdict three times, demanding that the ruling be reversed and the criminal case against him closed.
Charges against 14 other top managers and medical personnel from several medical institutions in the region were dropped before the trial began. Novosyolov, as the alleged organizer of the sale of the corpses, was the only one to be brought to trial.
Relatives of the dead have been, so far unsuccessfully, trying to convince the authorities to bring the corpses back to Russia for a proper burial. Dr von Hagens was not charged in the case, and was only questioned as a witness.
