Nashua ( NSHA), a maker of labels and specialty papers, was on the rise following the company's announcement that it received a favorable legal ruling from the Appellate Court of Illinois. On June 30, the court issued an order in the case filed by Phillippe Olczyk and others dismissing their appeal of a 2005 ruling in which Nashua was granted summary judgment. The Appellate Court found that it lacked appellate jurisdiction, Nashua said. Under Illinois law, the plaintiffs have 21 days to seek a rehearing or up to 35 days in which to petition the Illinois Supreme Court to hear an appeal. The suit was initially filed in 1996 against Cerion Technologies, Nashua and other defendants. The original complaint alleged that Cerion, a former unit of Nashua, had issued false and misleading statements and omitted the disclosure of certain material facts in connection with its initial public offering. The defendants denied the claims. Cerion ceased operations in 1998. Shares of Nashua were up 85 cents, or 12.8%, to $7.50.

Shares of Aurizon were down 15 cents, or 5.3%, to $2.70.
