The court issued the decision on an orders list dated 2/19/2013.
The appeal was filed after Ryan was convicted in 2006 of federal corruption charges in the license for bribes scandal through the secretary of state's office. He was appealing his conviction and prison sentence for racketeering, fraud and other crimes involving kickbacks for state contracts and property leases.
Ryan filed a variety of legal challenges, including allegations that prosecutors failed to prove he'd taken bribes.
His attorney, former Illinois Gov. Jim Thompson, said Ryan understands and accepts the decision.
"The district court has now spoken twice. The court of appeals has spoken twice. The Supreme Court has spoken. That is the end of it. We have come to the end of the road in the Ryan litigation," Thompson said.
After spending five years in prison, Ryan was released on home confinement on January 30, 2013. He's to spend the next six and a half months at his home in Kankakee.
However, late Sunday afternoon, at an Italian restaurant in Frankfort, the disgraced governor walked in the front door and sat down in what the manager calls "a secluded table." Ryan, seen in a photo with his daughter-in-law, Amy, who made the reservation, dined with son, George Ryan Jr., and two friends.
The terms of Ryan's release were spelled out publicly as confinement for 6-and-a-half months inside his Kankakee home with exceptions for work or church. On Tuesday morning, the U.S. Bureau of Prisons said inmates are granted permission to leave home confinement for a variety of reasons, but they would not confirm if Ryan's trip to the restaurant was approved.
When the I-Team contacted Ryan at home Monday he had no comment.
