A nearly decade-long dispute over the use of formulas for Bazooka bubble gum and other products made by Topps Co. is headed back to a district court following a decision by a federal appeals court.

The 2nd U.S. Circuit Court of Appeals reversed Southern District of New York Judge Charles Haight, finding that he erred in granting summary judgment to Cadbury Stani S.A.I.C. over rights to the formulas in parts of South America.
