"The rapporteur, Mr Koch, to whom we express our thanks for the work which he has done on this, has already pointed out that basically everything could have been somewhat more advanced had it not been for the inactivity on the part of the CEN, which has been very dilatory in drawing up and adapting the directive."
Le rapporteur, M. Koch, que nous remercions pour le travail qu'il a accompli, a signalé que, dans le fond, tout ceci pourrait déjà être un peu plus avancé sans la négligence du CEN, qui a énormément tardé à élaborer et à harmoniser la directive.
