DISCRIMINATION AGAINST A PROVIDER OF A SERVICE ON THE GROUNDS OF HIS NATIONALITY BUT ALSO ALL RESTRICTIONS ON HIS FREEDOM TO PROVIDE SERVICES IMPOSED BY REASON OF THE FACT THAT HE IS ESTABLISHED IN A MEMBER STATE OTHER THAN THAT IN WHICH THE SERVICE IS TO BE PROVIDED .
17 THE COURT HAS NEVERTHELESS ACCEPTED , IN PARTICULAR IN ITS JUDGMENTS OF 18 JANUARY 1979 ( JOINED CASES 110 AND 111/78 MINISTERE PUBLIC AND ANOTHER V VAN WESEMAEL AND OTHERS ( 1979 ) ECR 35 ) AND 17 DECEMBER 1981 ( CASE 279/80 WEBB ( 1981 ) ECR 3305 ), THAT REGARD BEING HAD TO THE PARTICULAR NATURE OF CERTAIN SERVICES , SPECIFIC REQUIREMENTS IMPOSED ON THE PROVIDER OF THE SERVICES CANNOT BE CONSIDERED TO BE INCOMPATIBLE WITH THE TREATY WHERE THEY HAVE AS THEIR PURPOSE THE APPLICATION OF RULES GOVERNING SUCH ACTIVITIES . HOWEVER , THE FREEDOM TO PROVIDE SERVICES , AS ONE OF THE FUNDAMENTAL PRINCIPLES OF THE TREATY , MAY BE RESTRICTED ONLY BY PROVISIONS WHICH ARE JUSTIFIED BY THE GENERAL GOOD AND WHICH ARE APPLIED TO ALL PERSONS OR UNDERTAKINGS OPERATING WITHIN THE TERRITORY OF THE STATE IN WHICH THE SERVICE IS PROVIDED IN SO FAR AS THAT INTEREST IS NOT SAFEGUARDED BY THE PROVISIONS TO WHICH THE PROVIDER OF A SERVICE IS SUBJECT IN THE MEMBER STATE OF HIS ESTABLISHMENT . IN ADDITION , SUCH REQUIREMENTS MUST BE OBJECTIVELY JUSTIFIED BY THE NEED TO ENSURE THAT PROFESSIONAL RULES OF CONDUCT ARE COMPLIED WITH AND THAT THE INTERESTS WHICH SUCH RULES ARE DESIGNED TO SAFEGUARD ARE PROTECTED .
18 IT MUST BE STATED THAT THE REQUIREMENT THAT AN INSURANCE UNDERTAKING WHICH IS ALREADY ESTABLISHED AND AUTHORIZED IN A MEMBER STATE AND WHICH WISHES TO PROVIDE SERVICES SOLELY AS A LEADING INSURER MUST OBTAIN AN AUTHORIZATION FROM THE AUTHORITIES OF THE STATE IN WHICH THE SERVICE IS PROVIDED AND HAVE A PERMANENT ESTABLISHMENT IN THAT STATE CONSTITUTES A SERIOUS RESTRICTION OF THE FREEDOM OF THAT LEADING INSURER TO PROVIDE SERVICES . SINCE , AS A RULE , INSURANCE UNDERTAKINGS CONDUCT BUSINESS AS LEADING INSURERS ONLY OCCASIONALLY , THE REQUIREMENT THAT THEY MUST GIVE NOTICE TO THE COMPETENT MINISTER AND OBTAIN HIS CONSENT MUST ALSO BE REGARDED AS A RESTRICTION WITHIN THE MEANING OF ARTICLE 59 OF THE TREATY , EVEN THOUGH THAT CONSENT IS GENERAL AND IS , IN PRACTICE , ACCORDED IN EVERY CASE , AS THE IRISH GOVERNMENT HAS STATED .
19 IT FOLLOWS THAT THOSE REQUIREMENTS MAY BE REGARDED AS COMPATIBLE WITH ARTICLES 59 AND 60 OF THE EEC TREATY ONLY IF IT IS ESTABLISHED THAT IN THE FIELD OF ACTIVITY CONCERNED THERE ARE IMPERATIVE REASONS RELATING TO THE PUBLIC INTEREST WHICH JUSTIFY RESTRICTIONS ON THE FREEDOM TO PROVIDE SERVICES , THAT THE PUBLIC INTEREST IS NOT ALREADY PROTECTED BY THE RULES OF THE STATE OF ESTABLISHMENT AND THAT THE SAME RESULT CANNOT BE OBTAINED BY LESS RESTRICTIVE RULES .
