Seventh Circuit Chief Judge Diane Wood said in a statement: “For more than 50 years Judge Posner has been one of the leading public intellectuals in the United States—indeed, in the world. He is one of the most distinguished people to ever sit on the federal bench. His opinions have had an impact around the world. He has produced an unparalleled body of scholarship—books, articles, and public commentary—covering virtually every legal topic that can be imagined.”
Posner was appointed by Ronald Reagan in 1981. He served as chief judge of the Seventh Circuit from 1993 to 2000.
He has also criticized the U.S. Supreme Court, which some pushed for him to join, as being too politicized.
