Article 14 of Directive 2008/95/EC of the European Parliament and of the Council of 22 October 2008 to approximate the laws of the Member States relating to trade marks, read in conjunction with Article 34(2) of Council Regulation (EC) No 207/2009 of 26 February 2009 on the [European Union] trade mark, must be interpreted as precluding an interpretation of national legislation according to which the invalidity or revocation of an earlier national mark, the seniority of which is claimed for an EU mark, may be established a posteriori only if the conditions for that invalidity or that revocation were met, not only on the date on which that earlier national mark was surrendered or the date on which it lapsed, but also on the date on which the judicial decision making that finding is taken.
