( 1 ) OF REGULATION NO 20, AFTER POSTPONING ON SEVERAL OCCASIONS " THE DATE OF THE INTRODUCTION OF THE LEVY SYSTEM INSTITUTED " BY THAT REGULATION, THE COUNCIL FINALLY FIXED THAT DATE IN ARTICLE 1 OF REGULATION NO 54/63/EEC AT " 2 SEPTEMBER 1962 AT THE LATEST ".
REGULATIONS NOS 86/63/EEC TO 89/63/EEC DIVIDED THESE PRODUCTS INTO TWO GROUPS AND FIXED FOR THE FIRST TIME THE AMOUNTS OF BOTH THE INTRA-COMMUNITY LEVIES ( REGULATIONS NOS 87/63 AND 89/63 ) AND THE THIRD COUNTRY LEVIES ( REGULATIONS NOS 86/63 AND 88/63 ) TO BE IMPOSED ON IMPORTS .
15 THE ANNEXES TO THESE REGULATIONS SHOW THAT THE LEVIES WERE TO BE IMPOSED ON IMPORTS EFFECTED DURING PERIODS BEGINNING FOR EACH GROUP ON 2 SEPTEMBER 1963 .
THUS, AS REGARDS PRODUCTS OTHER THAN LIVE SWINE AND PIG CARCASSES, THE PROVISIONS IN QUESTION CAME INTO EFFECT ON 2 SEPTEMBER 1963 .
16 ( 2 ) APART FROM CERTAIN EXCEPTIONS THE THIRD PARAGRAPH OF ARTICLE 32 OF THE BASIC REGULATION NO 121/67/EEC REPEALED REGULATION NO 20 WITH EFFECT FROM 1 JULY 1967 .
THE SECOND PARAGRAPH OF THE SAME ARTICLE PROVIDES THAT " THE SYSTEM ESTABLISHED BY THIS REGULATION SHALL APPLY FROM " THAT DATE, WITH THE EXCEPTION OF CERTAIN MEASURES WHICH ARE NOT RELEVANT TO THIS CASE .
IT FOLLOWS THAT THE PROHIBITION ON THE CHARGES IN DISPUTE, WHICH IS REPEATED IN ARTICLES 17 AND 19 OF THE NEW REGULATION AND, THEREFORE, THE INDIVIDUAL RIGHTS ARISING THEREFROM, CAME INTO EXISTENCE ON 1 JULY 1967 .
THEREFORE, AS REGARDS THE SYSTEM ESTABLISHED BY REGULATION NO 121/67, THE PROVISIONS IN QUESTION CAME INTO EFFECT ON 1 JULY 1967 .
17 ( 3 ) IT FOLLOWS FROM THE ABOVE CONSIDERATIONS THAT, UNDER THE SYSTEM ESTABLISHED IN REGULATION NO 20, THE PROHIBITION ON THE IMPOSITION BY THE MEMBER STATE OF THE CHARGES IN QUESTION WAS CONCOMITANT WITH THE OBLIGATION TO IMPOSE THE LEVIES PROVIDED FOR IN THAT REGULATION .
IT FOLLOWS ALSO THAT THIS OBLIGATION CAME INTO EFFECT ON 30 JULY 1962 OR 2 SEPTEMBER 1963, ACCORDING TO THE PRODUCTS INVOLVED .
MOREOVER, AS FROM THOSE DATES THE LEVIES IN QUESTION WERE APPLIED WITHOUT INTERRUPTION UNTIL 1 JULY 1967, THE DATE ON WHICH REGULATION NO 121/67 CAME INTO FORCE .
THAT REGULATION IS STILL IN FORCE .
18 THE REPLY TO THE QUESTION REFERRED BY THE NATIONAL COURT MUST THEREFORE BE THAT THE EFFECTS IN QUESTION CAME INTO EXISTENCE ON 30 JULY 1962 OR 2 SEPTEMBER 1963, ACCORDING TO THE PRODUCTS INVOLVED .

19 THE COSTS INCURRED BY THE GOVERNMENT OF THE ITALIAN REPUBLIC AND THE COMMISSION OF THE EUROPEAN COMMUNITIES, WHICH HAVE SUBMITTED OBSERVATIONS TO THE COURT, ARE NOT RECOVERABLE, AND AS THESE PROCEEDINGS ARE, IN SO FAR AS THE PARTIES TO THE MAIN ACTION ARE CONCERNED, IN THE NATURE OF A STEP IN THE ACTION PENDING BEFORE THE NATIONAL COURT, THE DECISION AS TO COSTS IS A MATTER FOR THAT COURT,
