Operation Greylord was an investigation conducted jointly by the Federal Bureau of Investigation, the IRS Criminal Investigation Division, the U.S. Postal Inspection Service, the Chicago Police Department Internal Affairs Division and the Illinois State Police into corruption in the judiciary of Cook County, Illinois... 

3+ yrs federal undercover operation took place in the 1980s. After the end of the undercover phase, the Greylord trials lasted ten years. Over 92 public officials were indicted (almost all in federal court), and most eventually were convicted, either by guilty pleas or trials....  agents obtained judicial and U.S. Department of Justice authorization to present staged court cases for the undercover agents/lawyers to fix in front of the corrupt judges. https://en.wikipedia.org/wiki/Operation_Greylord
