Moet voor de toepassing van de bij verordening nr. 2988/95 vastgestelde verjaringsregels elke handeling die de verjaring schorst wat de hoofdvordering betreft, worden geacht ook de verjaring voor de rente te schorsen, ook al laten de handelingen die de verjaring van de hoofdvordering schorsen, de rente onvermeld?
For the purpose of the application of the rules on limitation laid down by Regulation No 2988/95, must any act which interrupts the limitation period insofar as concerns the principal claim be regarded as also interrupting the time running in respect of interest, even if no mention is made of interest in the acts directed at the principal claim that interrupt the limitation period?
