George Ryan and a co-defendant lost another legal round at the Supreme Court on Tuesday and will remain in prison on federal racketeering and fraud convictions . Ex-Gov . George Ryan walks out of a Chicago , Illinois , courthouse after his April 2006 conviction . Ryan and businessman Larry Warner claimed they did not receive a fair trial , but the justices , without comment , refused to intervene in the case . Justice John Paul Stevens refused last fall to grant bail for the 74-year-old Ryan , a move that would have kept him out of jail to file more appeals . The disgraced ex-governor reported to a federal prison in Wisconsin in November to serve a 6½-year sentence . The men were convicted in April 2006 for fraud in a case stemming from bribes paid for various state licenses . Their lawyers claimed the trial judge improperly removed two jurors while deliberations in the case had commenced , but a federal appeals court upheld the convictions .

He also was noted for issuing a moratorium on capital punishment in his state in 2000 over concerns innocent inmates might be executed . The case decided Tuesday is Warner and Ryan v. U.S. ( 07-977 ) .
