Defense attorneys for the four former Commonwealth Edison executives and lobbyists convicted of bribing one of the state's most powerful politicians have asked a judge to drop the case. The four defendants, who have not be sentenced, want Judge Manish Shah to dismiss the indictment against them and issue an acquittal after a U.S. Supreme Court ruling on the federal bribery statute. In June, the U.S. Supreme Court struck down part of a federal bribery statute that makes it a crime for state and local officials to accept gifts valued at over $5,000 from a donor who had previously been awarded contracts or other government benefits thanks to the official's efforts. The 6-3 decision could affect how prosecutors across the country pursue public corruption cases.
