A five-year dispute over the legality of Quinn Glass' plant in the north of England has been finally settled, after the Supreme Court threw out an appeal against the 'unlawful' granting of retrospective planning permission for the site. The Supreme Court ordered that permission for Ardagh Glass to appeal against the decision be refused on the grounds that: "The application does not raise an arguable point of law of general public importance which ought to be considered by the Supreme Court at this time, bearing in mind that the case has already been the subject of judicial decision and reviewed on appeal." Ardagh Glass lodged the appeal after the Court of Appeal refused the company's claim that Cheshire West and Chester Council's decision to grant the Quinn Glass plant retrospective planning permission was unlawful.
