 The commission was co-chaired by the president of the Chicago Bar Association and the president of the Illinois Bar Association.They named John Paul Stevens, a private practitioner with a thriving antitrust practice, as their independent counsel, thus setting the stage for Stevens' meteoric rise to the Supreme Court of the United States.In 1969, the Greenberg Commission, appointed by the Illinois Supreme Court to investigate Sherman Skolnick's corruption allegations leveled at former Chief Justice Ray Klingbiel and current Chief Justice Roy J. Solfisburg, Jr., named Stevens as their counsel, meaning that he essentially served as the commission's special prosecutor.
