THAT THE DUTY ASSIGNED TO THE COURT BY ARTICLE 177 IS NOT THAT OF DELIVERING ADVISORY OPINIONS ON GENERAL OR HYPOTHETICAL QUESTIONS BUT OF ASSISTING IN THE ADMINISTRATION OF JUSTICE IN THE MEMBER STATES . IT ACCORDINGLY DOES NOT HAVE JURISDICTION TO REPLY TO QUESTIONS OF INTERPRETATION WHICH ARE SUBMITTED TO IT WITHIN THE FRAMEWORK OF PROCEDURAL DEVICES ARRANGED BY THE PARTIES IN ORDER TO INDUCE THE COURT TO GIVE ITS VIEWS ON CERTAIN PROBLEMS OF COMMUNITY LAW WHICH DO NOT CORRESPOND TO AN OBJECTIVE REQUIREMENT INHERENT IN THE RESOLUTION OF A DISPUTE . A DECLARATION BY THE COURT THAT IS HAS NO JURISDICTION IN SUCH CIRCUMSTANCES DOES NOT IN ANY WAY TRESPASS UPON THE PREROGATIVES OF THE NATIONAL COURT BUT MAKES IT POSSIBLE TO PREVENT THE APPLICATION OF THE PROCEDURE UNDER ARTICLE 177 FOR PURPOSES OTHER THAN THOSE APPROPRIATE FOR IT .
