25MOREOVER , IN SO FAR AS THE PRACTICE OF THE PROFESSION OF VETERINARY SURGEON IS CONCERNED , THIS IDEA WAS FULLY CONFIRMED BY A DECLARATION CONCERNING THE DEFINITION OF THE PERSONS COVERED BY THE DIRECTIVES , WHICH WAS RECORDED IN THE MINUTES OF THE MEETING OF THE COUNCIL DURING WHICH THE DIRECTIVES RELATING TO THE MUTUAL RECOGNITION OF DIPLOMAS AND THE CO-ORDINATION OF PROVISIONS LAID DOWN BY LAW , REGULATION OR ADMINISTRATIVE ACTION IN RESPECT OF THE ACTIVITIES OF VETERINARY SURGEONS WERE ADOPTED .
26THAT DECLARATION STATES THAT : ' ' THE COUNCIL REAFFIRMS THAT IT IS TO BE UNDERSTOOD THAT FREEDOM OF ESTABLISHMENT , PARTICULARLY FOR THE HOLDERS OF CERTIFICATES OBTAINED IN OTHER MEMBER STATES , MUST BE ACCORDED ON THE SAME TERMS TO NATIONALS OF OTHER MEMBER STATES AND TO NATIONALS OF THE MEMBER STATE CONCERNED , AS IS THE CASE WITH OTHER DIRECTIVES .
27IT APPEARS , BOTH FROM THE WORDING OF THE QUESTION REFERRED TO THE COURT AND FROM THE RECITALS TO THE DECISION OF THE NATIONAL COURT , THAT THAT COURT WOULD ALSO LIKE TO KNOW WHETHER THE FACT THAT THE PERSON CONCERNED HAD ACQUIRED FRENCH NATIONALITY BY NATURALIZATION AT A DATE SUBSEQUENT TO THAT ON WHICH HE HAD OBTAINED THE ITALIAN DEGREES AND QUALIFICATIONS ON WHICH HE RELIES , WAS OF SUCH A NATURE AS TO INFLUENCE THE REPLY TO THE QUESTION WHICH IT HAS PUT .
28THERE IS NO PROVISION OF THE TREATY WHICH , WITHIN THE FIELD OF APPLICATION OF THE TREATY , MAKES IT POSSIBLE TO TREAT NATIONALS OF A MEMBER STATE DIFFERENTLY ACCORDING TO THE TIME AT WHICH OR THE MANNER IN WHICH THEY ACQUIRED THE NATIONALITY OF THAT STATE , AS LONG AS , AT THE TIME AT WHICH THEY RELY ON THE BENEFIT OF THE PROVISIONS OF COMMUNITY LAW , THEY POSSESS THE NATIONALITY OF ONE OF THE MEMBER STATES AND THAT , IN ADDITION , THE OTHER CONDITIONS FOR THE APPLICATION OF THE RULE ON WHICH THEY RELY ARE FULFILLED .
29HENCE , IN ASSESSING THE RIGHTS OF A NATIONAL OF A MEMBER STATE , IN PERIODS BOTH PRIOR AND SUBSEQUENT TO THAT REFERRED TO IN THE DIRECTIVES CITED ABOVE , THE DATE ON WHICH HE ACQUIRED THE STATUS OF A NATIONAL OF A MEMBER STATE IS IRRELEVANT AS LONG AS HE POSSESSES IT AT THE TIME AT WHICH HE RELIES UPON THE PROVISIONS OF COMMUNITY LAW , THE ENJOYMENT OF WHICH IS LINKED TO THE STATUS OF A NATIONAL OF A MEMBER STATE .
30IT FOLLOWS FROM THE CONSIDERATIONS SET OUT ABOVE THAT ARTICLE 52 OF THE TREATY MUST BE INTERPRETED AS MEANING THAT FOR THE PERIOD PRIOR TO THE DATE ON WHICH THE MEMBER STATES ARE REQUIRED TO HAVE TAKEN THE MEASURES NECESSARY TO COMPLY WITH COUNCIL DIRECTIVES NOS 78/1026 AND 78/1027 OF 18 DECEMBER 1978 , THE NATIONALS OF A MEMBER STATE CANNOT RELY ON THAT PROVISION WITH A VIEW TO PRACTISING THE PROFESSION OF VETERINARY SURGEON IN THAT MEMBER STATE ON ANY
