OF THE KIND IN FORCE IN LUXEMBOURG , WHEREBY THE INDIVIDUAL REFERENCE QUANTITIES OF FIRMS WHICH HAVE CEASED PRODUCTION ARE ASSIGNED TO THEIR DAIRIES , IS LIABLE TO CREATE AN UNJUSTIFIED ADVANTAGE FOR THE SUPPLIERS OF THOSE DAIRIES TO THE DETRIMENT OF SUPPLIERS OF OTHER DAIRIES . FOR THEIR PART , THE LUXEMBOURG GOVERNMENT AND THE COMMISSION ARGUE THAT UNDER THE COMMUNITY RULES PURCHASERS ' REFERENCE QUANTITIES MUST BE FIXED IN THE LIGHT OF THE QUANTITIES ACTUALLY COLLECTED DURING THE REFERENCE YEAR , EXCEPT WHERE A SPECIFIC PROVISION TO THE CONTRARY AUTHORIZES SUBSEQUENT EVENTS TO BE TAKEN INTO ACCOUNT .
19 IT MUST BE BORNE IN MIND IN THAT CONNECTION THAT ARTICLE 7 ( 2 ) OF REGULATION NO 857/84 IN CONJUNCTION WITH ARTICLE 6 ( 1 ) ( D ) OF COMMISSION REGULATION ( EEC ) NO 1371/84 OF 16 MAY 1984 LAYING DOWN DETAILED RULES FOR THE APPLICATION OF THE ADDITIONAL LEVY REFERRED TO IN ARTICLE 5C OF REGULATION ( EEC ) NO 804/68 ( OFFICIAL JOURNAL 1984 , L 132 , P . 11 ) PROVIDES THAT , UNDER FORMULA B , THE PURCHASER ' S REFERENCE QUANTITY IS TO BE ADJUSTED , INTER ALIA , IN ORDER TO TAKE ACCOUNT OF CHANGES BY PRODUCERS FROM ONE PURCHASER TO ANOTHER , SUBJECT TO MEMBER STATES ' BEING ABLE TO PROVIDE THAT A PART OF THE QUANTITIES IN QUESTION BE ADDED TO THE RESERVE REFERRED TO IN ARTICLE 5 OF REGULATION NO 857/84 ( THE NATIONAL RESERVE ). FURTHERMORE , ARTICLE 4 ( 1 ) ( A ) AND ARTICLE 4 ( 2 ) OF REGULATION NO 857/84 PROVIDE FOR THE ADDITION TO THE NATIONAL RESERVE OF REFERENCE QUANTITIES FREED WHERE MEMBER STATES GRANT COMPENSATION TO PRODUCERS WHO UNDERTAKE TO DISCONTINUE MILK PRODUCTION DEFINITIVELY .
20 BUT THERE IS NO PROVISION IN THE RELEVANT COMMUNITY RULES FOR THE ADJUSTMENT OF REFERENCE QUANTITIES IN THE EVENT THAT A PRODUCER DISCONTINUES PRODUCTION SPONTANEOUSLY . IT MUST THEREFORE BE CONSIDERED WHETHER , EVEN IN THE ABSENCE OF AN EXPRESS PROVISION TO THAT EFFECT , SUCH AN EVENTUALITY MUST BE TREATED IN THE SAME WAY AS THE CASES MENTIONED IN THE AFORESAID PROVISIONS .
21 IN THIS CONNECTION IT IS APPROPRIATE TO POINT OUT THAT , IN ITS JUDGMENT OF 13 DECEMBER 1983 IN CASE 218/82 COMMISSION V COUNCIL ( 1983 ) ECR 4063 , THE COURT TOOK THE VIEW THAT WHEN IT IS NECESSARY TO INTERPRET A PROVISION OF SECONDARY COMMUNITY LAW , PREFERENCE SHOULD AS FAR AS POSSIBLE BE GIVEN TO THE INTERPRETATION WHICH RENDERS THE PROVISION CONSISTENT WITH THE TREATY ; IN THIS CASE REGARD MUST BE HAD SPECIFICALLY TO THE REQUIREMENT NOT TO DISCRIMINATE BETWEEN PRODUCERS WITHIN THE COMMUNITY WHICH IS LAID DOWN IN ARTICLE 40 ( 3 ) OF THE EEC TREATY .
22 TO INTERPRET THE REGULATION AS MEANING THAT THE INDIVIDUAL REFERENCE QUANTITY OF A PRODUCER WHO CEASED TRADING SPONTANEOUSLY SHOULD REMAIN AT THE DISPOSAL OF THE PURCHASER WOULD CREATE DISCRIMINATION BETWEEN PRODUCERS . THE
