The Supreme Court has rejected former Illinois Gov. George Ryan's appeal of his federal racketeering and fraud conviction.
The justices have no comment on their action, in response to Ryan's claim that he and his fellow defendant, businessman Larry Warner did not receive a fair trial.
Their lawyers argued that the trial judge replaced two jurors with alternates after deliberations in the case had already begun.
Ryan, 74, is serving a 6 1/2 year sentence in federal prison.
The Chicago-based 7th U.S. Circuit Court of Appeals earlier upheld the convictions.
