U.S. District Judge Monti Belot has denied a motion by federal prosecutors seeking a court hearing on whether allowing defense attorneys to represent multiple clients.
They also questioned whether Gary Hall should be allowed to pay the legal bills for his co-defendants.
Belot wrote that while he was concerned if that was happening it didn't automatically create a conflict.
Hall, 66, of rural Joplin, is president and owner of Galena-based Sunflower Supply Co.
He and seven other people and three businesses face a 43-count federal indictment alleging multiple counts of mail fraud, wire fraud, money laundering and conspiracy to commit money laundering.
Prosecutors claim the group committed $25 million in tobacco tax fraud against Oklahoma and American Indian tribes.
