IN RELATION TO NATIONAL PRICE-CONTROL MEASURES
17 IN ITS THIRD QUESTION THE NATIONAL COURT ASKS THE COURT TO STATE WHETHER THE COMMON ORGANIZATION OF THE MARKET IN MILK AND MILK PRODUCTS LAID DOWN IN REGULATION NO 804/68 OF 27 JUNE 1968 , EITHER ALONE OR IN CONJUNCTION WITH THE COMMON ORGANIZATION OF THE MARKET IN BEEF AND VEAL LAID DOWN IN REGULATION NO 805/68 , PROHIBIT MEMBER STATES FROM APPLYING NATIONAL PRICE-FREEZE RULES TO THE MILK-FEED PRODUCTS FOR CALVES IN QUESTION . IN ITS FIFTH QUESTION THE NATIONAL COURT ALSO ASKS WHETHER THE COMMON ORGANIZATION OF THE MARKET REFERRED TO ABOVE PROHIBITS MEMBER STATES FROM APPLYING NATIONAL PRICE-FREEZE RULES WHICH DO NOT CONTAIN SPECIAL PROVISIONS FOR AGRICULTURAL PRODUCTS GOVERNED BY DECISIONS ADOPTED BY THE COMMUNITY .
SINCE THE CONTENT OF THOSE TWO QUESTIONS IS RELATED THEY MUST BE CONSIDERED TOGETHER .
18 THE COURT HAS CONSISTENTLY HELD ( CF . JUDGMENT OF 23 JANUARY 1975 IN CASE 31/74 , GALLI ( 1975 ) ECR 47 ; JUDGMENTS OF 26 FEBRUARY 1976 IN CASE 65/75 , TASCA ( 1976 ) ECR 291 , AND IN JOINED CASES 88 TO 90/75 , SADAM ( 1976 ) ECR 323 ; JUDGMENT OF 29 JUNE 1978 IN CASE 154/77 , DECHMANN ( 1978 ) ECR 1573 , AND JUDGMENT OF 12 JULY 1979 IN CASE 223/78 , GROSOLI ( 1979)ECR ) THAT IN SECTORS COVERED BY A COMMON ORGANIZATION OF THE MARKET - EVEN MORE SO WHEN THAT ORGANIZATION IS BASED ON A COMMON PRICE SYSTEM - MEMBER STATES CAN NO LONGER INTERFERE THROUGH NATIONAL PROVISIONS TAKEN UNILATERALLY IN THE MACHINERY OF PRICE FORMATION AS ESTABLISHED UNDER THE COMMON ORGANIZATION . THAT CASE-LAW HAS MADE CLEAR THAT THE PROVISIONS OF A COMMUNITY AGRICULTURAL REGULATION ESTABLISHING A PRICE SYSTEM WHICH IS APPLICABLE AT THE PRODUCTION AND WHOLESALE STAGES LEAVE MEMBER STATES FREE - WITHOUT PREJUDICE TO OTHER PROVISIONS OF THE TREATY - TO TAKE THE APPROPRIATE MEASURES RELATING TO PRICE FORMATION AT THE RETAIL AND CONSUMPTION STAGES , ON CONDITION THAT THEY DO NOT JEOPARDIZE THE AIMS OR FUNCTIONING OF THE COMMON ORGANIZATION OF THE MARKET IN QUESTION .
19 IN THE SAME CASE-LAW THE COURT HAS ALSO STATED THAT IN EVERY CASE IT IS FOR THE NATIONAL COURT TO DECIDE WHETHER THE NATIONAL MEASURES TAKEN IN RELATION TO PRICES WHICH IT IS CALLED UPON TO CONSIDER PRODUCE SUCH EFFECTS AS TO MAKE THEM INCOMPATIBLE WITH THE COMMUNITY PROVISIONS ON THE MATTER . IN THAT CONNEXION THE PARTICULAR NATURE OF THE ORGANIZATION OF THE MARKETS IN THE SECTOR IN QUESTION MUST BE TAKEN INTO ACCOUNT .
20 AS REGARDS THE PARTICULAR CHARACTERISTICS OF THE COMMON ORGANIZATION OF THE MARKET IN MILK AND MILK PRODUCTS SET UP BY REGULATION NO 804/68 IT MUST BE POINTED OUT THAT THAT ORGANIZATION INVOLVES A PRICE SYSTEM AND A TRADING SYSTEM . THE PRICE SYSTEM IS BASED UPON A ' ' TARGET PRICE ' ' FOR MILK , A ' ' THRESHOLD PRICE ' ' FOR CERTAIN MILK PRODUCTS ,
