In the papers filed with the 2nd US Circuit Court of Appeals, Taubman’s lawyers said he was not given the opportunity during the trial to explain why he met a dozen times with former Christie’s International chairman Anthony Tennant during the time when the price-fixing occurred. The lawyers say the topics addressed in the meetings with Tennant were legitimate.

Taubman, who remains Sotheby’s controlling shareholder, was convicted in December of conspiracy to violate antitrust laws and was sentenced last month to a year and a day in prison and fined $7.5m. He is to report to prison on August 1.
