THE SERVICE PROVIDED .
28 IT APPEARS FROM THE DOCUMENTS BEFORE THE COURT AND THE INFORMATION PROVIDED BY THE PARTIES THAT , IN THE CASE OF BOTH RIGHT-HAND-DRIVE AND LEFT-HAND-DRIVE VEHICLES , IN ORDER TO ISSUE A CERTIFICATE OF CONFORMITY IT IS NECESSARY TO DETERMINE FROM THE CHASSIS NUMBER THE DATE OF MANUFACTURE OF THE VEHICLE . IT IS THEN POSSIBLE TO IDENTIFY THE NUMBER OF THE CORRESPONDING NTA CERTIFICATE . IT IS , THEREFORE , A SIMPLE ADMINISTRATIVE CHECK WHICH CANNOT ENTAIL SIGNIFICANT COSTS . FOR LEFT-HAND-DRIVE VEHICLES THE CERTIFICATE IS IN PRINCIPLE ISSUED BEFORE CONVERSION , IF THEY ARE CONVERTED TO RIGHT-HAND-DRIVE . THE ONLY DIFFERENCE IN RELATION TO THE ISSUE OF A CERTIFICATE FOR A RIGHT-HAND-DRIVE VEHICLE LIES IN THE NEED TO VERIFY THAT THE FOUR ALTERATIONS ESSENTIAL FOR A LEFT-HAND-DRIVE VEHICLE HAVE BEEN MADE , NAMELY THE ADJUSTMENT OF HEADLIGHTS , FULL BEAM AND DIPPED , THE CALIBRATION OF THE SPEEDOMETER IN MILES PER HOUR , THE ADAPTATION OF THE REAR FOG LAMP AND THE ADDITION OF A WING-MIRROR ON THE RIGHT FRONT DOOR . THAT VERIFICATION DOES NOT REQUIRE AN INSPECTION OF THE VEHICLE . IT IS EFFECTED ON THE BASIS OF A CERTIFICATE FURNISHED BY A GARAGE AND , ON THE BASIS OF THE COST INCURRED , CANNOT THEREFORE JUSTIFY THE CHARGING OF DIFFERENT FEES FOR THE ISSUE OF CERTIFICATES OF CONFORMITY ACCORDING TO WHETHER THE VEHICLES ARE RIGHT-HAND-DRIVE OR LEFT-HAND-DRIVE . INITIALLY THE FEE FOR LEFT-HAND-DRIVE VEHICLES WAS SIX TIMES GREATER THAN THAT FOR RIGHT-HAND-DRIVE VEHICLES .
29 MOREOVER , BL ITSELF ADMITTED AT THE HEARING THAT THE DIFFERENCE WHICH EXISTED AT ONE TIME ACCORDING TO WHETHER THE CERTIFICATE WAS REQUESTED BY A DEALER , WHO WAS CHARGED UKL 150 , OR BY A PRIVATE INDIVIDUAL , WHO WAS CHARGED ONLY UKL 100 , WAS NOT BASED ON THE COST BUT ON THE CONSIDERATION THAT THE TRADER WHO WAS CARRYING OUT A TRANSACTION FOR GAIN COULD BE REQUIRED TO PAY A HIGHER FEE . THE FACT THAT THE FEE WAS FIRST REDUCED TO UKL 100 AND THEN UKL 50 , WHILST FOR RIGHT-HAND-DRIVE VEHICLES IT REMAINED AT UKL 25 , ALSO SUGGESTS THAT IT WAS FIXED SOLELY WITH A VIEW TO MAKING THE RE-IMPORTATION OF LEFT-HAND-DRIVE VEHICLES LESS ATTRACTIVE .
30 IN THOSE CIRCUMSTANCES , THE COMMISSION WAS ENTITLED TO CONCLUDE THAT THE FEE WAS FIXED AT A LEVEL WHICH WAS CLEARLY DISPROPORTIONATE TO THE ECONOMIC VALUE OF THE SERVICE PROVIDED AND THAT THAT PRACTICE CONSTITUTED AN ABUSE BY BL OF THE MONOPOLY IT HELD BY VIRTUE OF THE BRITISH RULES .
31 BL FURTHER ARGUES THAT THE FEE OF UKL 150 WAS CHARGED ONLY FROM 1 JULY 1981 UNTIL THE EXPIRY OF THE NTA CERTIFICATE IN OCTOBER 1981 , WHICH WAS TOO SHORT A PERIOD FOR IT TO BE CONSIDERED AN INFRINGEMENT .
32 IT IS TRUE THAT , WHEN THE INFRINGEMENT WAS POINTED OUT TO IT BY THE COMMISSION , BL QUICKLY REDUCED THE AMOUNT OF THE FEE FROM UKL 150
