AUTHORITIES HAVE EXTENDED TO NON-MEMBERS THE OBLIGATION TO COMPLY WITH RULES LAID DOWN BY A PRODUCERS ' ORGANIZATION AND TO CONTRIBUTE TO THE FINANCING OF ITS ACTIVITIES .
12 IT MUST ALSO BE POINTED OUT THAT REGULATION NO 1035/72 INCLUDES A NUMBER OF PROVISIONS REGARDING PRODUCERS ' ORGANIZATIONS AND THE ACTIVITIES WHICH THEY MAY ENGAGE IN WITH REGARD TO INTERVENTION ON THE MARKET . IN SO FAR AS THOSE PROVISIONS ARE INTENDED TO ESTABLISH AN EXHAUSTIVE SCHEME OF REGULATION , THE MEMBER STATES NO LONGER HAVE ANY POWER TO ADD SUPPLEMENTARY REGULATIONS , FOR EXAMPLE BY EXTENDING TO NON-MEMBERS RULES WHICH UNDER REGULATION NO 1035/72 CONCERN ONLY THE MEMBERS OF PRODUCERS ' ORGANIZATIONS .
13 IN ORDER TO REPLY TO THE QUESTION RAISED BY THE NATIONAL COURT IT IS THEREFORE NECESSARY TO ASCERTAIN WHETHER AND TO WHAT EXTENT REGULATION NO 1035/72 PRECLUDES THE EXTENSION OF RULES ESTABLISHED BY PRODUCERS ' ORGANIZATIONS TO PRODUCERS WHO ARE NOT MEMBERS , EITHER BECAUSE THE EXTENSION OF THOSE RULES AFFECTS A MATTER WITH WHICH THE COMMON ORGANIZATION OF THE MARKET HAS DEALT EXHAUSTIVELY OR BECAUSE THE RULES SO EXTENDED ARE CONTRARY TO THE PROVISIONS OF COMMUNITY LAW OR INTERFERE WITH THE PROPER FUNCTIONING OF THE COMMON ORGANIZATION OF THE MARKET .

THERE ARE COMMUNITY PROCEDURES FOR ADOPTING THE STANDARDS IN QUESTION , AND WHEN SUCH NORMS HAVE BEEN ADOPTED THE PRODUCTS TO WHICH THEY APPLY MAY NOT BE DISPLAYED OR OFFERED FOR SALE , SOLD , DELIVERED OR MARKETED IN ANY OTHER MANNER UNLESS THEY CONFORM TO THE STANDARDS , SUBJECT TO EXCEPTIONS PROVIDED FOR IN REGULATION NO 1035/72 .
16 IN THE LIGHT OF THE EXHAUSTIVE NATURE OF THE COMMUNITY SYSTEM OF QUALITY STANDARDS , RULES ON GRADING , SIZE , WEIGHT AND PRESENTATION LAID DOWN BY PRODUCERS ' ORGANIZATIONS FOR PRODUCTS TO WHICH REGULATION NO 1035/72 APPLIES CANNOT BE MADE COMPULSORY FOR PRODUCERS WHO ARE NOT MEMBERS , SINCE SUCH AN EXTENSION IS NOT PROVIDED FOR BY THE RELEVANT PROVISIONS OF COMMUNITY LAW .
17 THE INTER-MINISTERIAL ORDERS REFERRED TO IN THE JUDGMENT OF THE NATIONAL COURT ALSO EXTENDED TO NON-MEMBER PRODUCERS THE OBLIGATION TO OFFER THEIR ENTIRE CROP FOR PUBLIC SALE EXCLUSIVELY AT MARKETS APPROVED BY CERAFEL AND TO CONTRIBUTE TO THE OPERATION OF THE WITHDRAWAL PRICE SCHEME .
