Photograph: iStockThe Court of Appeal (CoA) has overturned a High Court decision which found an Irish jeans manufacturer had, since 1979, “dishonestly and wrongfully” copied the “Diesel” trademark of the popular Italian clothing brand. The Supreme Court has since upheld a 2001 High Court decision refusing Montex’s registration. On Tuesday, Ms Justice Niamh Hyland, on behalf of the three-judge court, overturned Mr Justice Cregan’s decision and allowed the Montex appeal. She said the question as to the proprietorship of the mark was decided by the High Court in 2001. Ms Justice Hyland said as the Supreme Court had already upheld that High Court decision meant the matter had already been decided.
