OF REGULATION NO 1293/79 , UNTIL IT WAS DECLARED VOID BY THE COURT , HAD HELD ISOGLUCOSE PRODUCERS TO OBSERVE THE QUOTAS WHICH IT LAID DOWN AND THUS RENDERED SUPERFLUOUS THEIR REINSTATEMENT BY THE CONTESTED REGULATION . IN FACT , IN ADDITION TO THE LEGAL BASIS WHICH THE CONTESTED REGULATION GAVE TO THE SYSTEM OF QUOTAS DURING THE PERIOD IN QUESTION FROM 1 JULY 1979 TO 30 JUNE 1980 , THE MAINTENANCE OF LEVIES DURING THAT PERIOD , WHICH WAS NECESSARY TO ATTAIN THE OBJECTIVES OF PUBLIC INTEREST PURSUED BY THE COUNCIL , MADE IT NECESSARY TO FIX THE QUOTAS UPON WHICH THE AMOUNT OF THOSE LEVIES DEPENDED .
8 THUS THE COUNCIL WAS LAWFULLY ENTITLED TO CONSIDER THAT THE OBJECTIVE TO BE ACHIEVED IN THE GENERAL INTEREST , NAMELY THE STABILIZATION OF THE COMMUNITY MARKET IN SWEETENERS WITHOUT ARBITRARY DISCRIMINATION BETWEEN TRADERS , REQUIRED THE CONTESTED PROVISIONS TO BE RETROACTIVE IN NATURE AND THUS THE FIRST OF THE CONDITIONS WHICH THE COURT LAYS DOWN FOR THE APPLICABILITY RATIONE TEMPORIS OF A COMMUNITY MEASURE TO A DATE PRIOR TO THE DATE OF ITS PUBLICATION MAY BE REGARDED AS SATISFIED .
9 TO ASCERTAIN WHETHER THE SECOND OF THE CONDITIONS SET OUT ABOVE IS SATISFIED IT IS NECESSARY TO INQUIRE WHETHER THE ACTION OF THE COUNCIL IN PUBLISHING ON 17 FEBRUARY 1981 REGULATION NO 387/81 HAS FRUSTRATED A LEGITIMATE EXPECTATION ON THE PART OF THE APPLICANTS TO THE EFFECT THAT THE PRODUCTION OF ISOGLUCOSE WOULD NOT BE REGULATED DURING THE PERIOD FROM 1 JULY 1979 TO 30 JUNE 1980 , THE PERIOD TO WHICH THAT REGULATION MAKES APPLICABLE ARTICLE 9 RELATING TO QUOTAS AND PRODUCTION LEVIES ON ISOGLUCOSE WHICH IT INSERTED IN REGULATION NO 1111/77 .
10 IT SHOULD FIRST BE POINTED OUT THAT THE CONTESTED PROVISIONS OF REGULATION NO 387/81 DO NOT INCLUDE ANY NEW MEASURES AND MERELY REPRODUCE THE PROVISIONS OF COUNCIL REGULATION NO 1293/79 DECLARED VOID BY THE COURT ON 29 OCTOBER 1980 .
11 IN VIEW OF THE FACT THAT COUNCIL REGULATION NO 1293/79 OF 25 JUNE 1979 RETAINED ITS FULL EFFECT WITHIN THE COMMUNITY LEGAL ORDER UNTIL IT WAS DECLARED VOID , SO THAT THE NATIONAL AUTHORITIES RESPONSIBLE FOR ITS IMPLEMENTATION WERE REQUIRED TO SUBJECT THE PRODUCTION OF ISOGLUCOSE TO THE RESTRICTIVE SYSTEM WHICH IT LAID DOWN , SUCH A LEGITIMATE EXPECTATION COULD ONLY BE FOUNDED ON THE UNFORESEEABILITY OF THE REINSTATEMENT WITH RETROACTIVE EFFECT OF THE MEASURES CONTAINED IN REGULATION NO 1293/79 DECLARED VOID BY THE COURT .
12 IN THE PRESENT CASE THE APPLICANT CANNOT CLAIM ANY LEGITIMATE EXPECTATION WORTHY OF PROTECTION .
13 IN THE FIRST PLACE THE TRADERS CONCERNED BY THE RULES IN QUESTION ARE LIMITED IN NUMBER AND ARE REASONABLY WELL AWARE OF THE INTERDEPENDENCE OF THE MARKETS IN LIQUID SUGAR AND ISOGLUCOSE , OF THE SITUATION OF THE COMMUNITY MARKET IN SWEETENERS AND THEREFORE OF THE CONSEQUENCES WHICH , FOLLOWING THE DECLARATION THAT REGULATION NO 1293/79 WAS VOID , THE IMPOSITION ON THE PRODUCTION OF SUGAR IN RESPECT OF THE
