The latest effort to nullify the conviction Bout has met an unreceptive audience of U.S. appeals court judges. All three judges on a panel of the 2nd U.S. Circuit Court of Appeals hearing an appeal on behalf of Bout expressed skepticism Monday, Oct. 31, 2016, about his claims of unfair prosecution.
