PERSON CONCERNED IS PROHIBITED FROM CONTINUING TO IMPORT OR TO EXPORT BETWEEN 4 AUGUST 1968 AND THE DATE ON WHICH HE CHOOSES TO LODGE HIS APPLICATION .
13 THIS MUST APPLY WITH EVEN GREATER FORCE IN VIEW OF THE FACT THAT THE TRADERS CONCERNED MAY BE BOUND BY CONTRACTUAL DELIVERY DATES AND THAT THE REGULATION SHOULD NOT BE INTERPRETED IN SUCH A WAY AS TO INCREASE THE DIFFICULTIES OF IMPLEMENTING SUCH OBLIGATIONS .
14 IN ANY EVENT, SINCE THE ARTICLE DOES NOT LAY DOWN THOSE CONDITIONS AND THEY DO NOT ARISE FROM THE GROUNDS WHICH FORM THE BASIS OF THE DISPUTED PROVISION, THERE IS NO REASON TO ADD TO THE LEGAL TEXT CONDITIONS WHICH IT DOES NOT CONTAIN EITHER EXPRESSLY OR BY IMPLICATION .
15 CONSEQUENTLY THE APPLICATION FOR CANCELLATION NEED NOT NECESSARILY REFER TO THE ENTIRE QUOTA STILL OUTSTANDING AT 4 AUGUST 1968 .
16 AN APPLICATION FOR CANCELLATION MUST THUS BE CONSIDERED EVEN IF A TRACER HAS BEFORE THE DATE OF HIS APPLICATION IMPORTED OR EXPORTED A PART OF THE BALANCE REMAINING ON 4 AUGUST 1968 TO WHICH THE ADVANCE FIXING RELATES .
17 THE REPLY THUS GIVEN TO THE FIRST QUESTION MAKES THE SECOND IRRELEVANT .
18 THE THIRD QUESTION ASKS WHETHER A TRADER WHO LODGES AN APPLICATION FOR CANCELLATION AFTER CONTINUING TO IMPORT OR EXPORT AFTER 4 AUGUST 1968 MAY APPLY FOR THE CANCELLATION OF ALL OR PART OF THE BALANCE OF THE QUOTA FIXED IN ADVANCE WHICH IS OUTSTANDING AT THE DATE OF LODGING THE APPLICATION .
19 IT IS CLEAR FROM THE WORDING OF ARTICLE 7, IN ACCORDANCE WITH WHICH THE APPLICATION RELATES TO THE CANCELLATION OF THE CERTIFICATE OR DOCUMENT CERTIFYING THE ADVANCE FIXING, THAT ONLY THE COMPLETE CANCELLATION OF THE CERTIFICATE CAN BE ENVISAGED CONSEQUENTLY INVOLVING THE CANCELLATION OF THE ENTIRE BALANCE .
20 FURTHERMORE, THIS INTERPRETATION CORRESPONDS TO THE RESTRICTED SCOPE OF THE EXCEPTION MADE BY THE SAID ARTICLE 7 TO THE PRINCIPLE OF THE IMMUTABILITY OF ADVANCE FIXINGS .
21 MOREOVER, SINCE SUCH CANCELLATIONS DISTURB THE PROPER FUNCTIONING OF THE SYSTEMS OF ORGANIZATION OF THE MARKETS, THERE CAN BE NO JUSTIFICATION FOR FAVOURING THEIR INCREASE WHEN THEY EXCEED THE LEGAL GROUNDS ON WHICH ARTICLE 7 WAS BASED .
22 CONSEQUENTLY, THE CANCELLATION OF THE ADVANCE FIXING MUST REFER TO THE ENTIRE QUOTA OUTSTANDING AT THE DATE OF LODGING THE APPLICATION .
23 THE FOURTH QUESTION ASKS WHETHER IF THE REPLY TO THE FIRST QUESTION IS IN THE NEGATIVE, IT IS ALSO POSSIBLE TO CANCEL THE ADVANCE FIXING WITH REGARD TO ONE OR MORE IMPORTATIONS OR EXPORTATIONS WHICH WERE EFFECTED BETWEEN 4 AUGUST 1968 AND THE DATE OF THE APPLICATION FOR CANCELLATION .
24 RETROACTIVE CANCELLATION WOULD PRECLUDE THE FORWARD PLANNING ON WHICH THE AUTHORITIES RESPONSIBLE FOR THE ADMINISTRATION OF THE AGRICULTURAL MARKETS MAY PROPERLY RELY IN ASSESSING THEIR CHARGES OR REVENUES AND IN DETERMINING MARKET TRADE .
25 SUCH AN INTERPRETATION WOULD, FURTHERMORE, EXCEED THE OBJECTIVES OF ARTICLE 7 WHICH AIM AT PROTECTING TRADERS AGAINST VIOLATION OF THE PRINCIPLE OF
