A Chicago federal judge on Thursday entered a final judgment of $20 million against Palatine, Ill.’s Square D Company and in favor of the late Frank Calabrese after rejecting the company’s request to set aside a $13.2 million jury verdict entered on Jan. 26.

Indeed, U.S. District Court Judge Harry D. Leinenweber added $6.8 million in prejudgment interest to the jury verdict, which came after a long and bitterly-fought trial.
