Argument should be saved for the Argument section of your brief. In Illinois, Supreme Court Rule 341 prohibits argument in the Fact section. When Commonwealth Edison filed a brief that stepped into foul grounds, the Second District Appellate Court “admonish[ed] counsel for ComEd to comply with the supreme court rules in the future.” The court read Com Ed’s facts, but disregarded the statements that violated Rule 341.
The whole case, Village of Roselle v. Commonwealth Edison Co., No. 2-06-0294 (2006), is right here.
