Ex-Ill. Gov. Ryan appeals parts of conviction based on high court's ruling on honest services

Imprisoned former Illinois Gov. George Ryan is seeking to have elements of his conviction thrown out based on a U.S. Supreme Court ruling earlier this year.

In a federal court filing in Chicago, Ryan's attorneys cited the ruling that put limits on so-called honest services provisions. Such laws bar public officials from denying taxpayers honest services.

The Republican is serving a six-and-a-half year prison sentence. Not all the charges a jury convicted him on in 2006 are tied to the disputed provision.

During former Illinois Gov. Rod Blagojevich's recent corruption trial, defense attorneys also cited the honest services ruling in a motion for a mistrial. The judge rejected it.

Blagojevich's trial ended in a hung jury on most counts and he's expected to be retried.
