TEACHERS AT A EUROPEAN SCHOOL SITUATED ON ITS TERRITORY .
54 IN ORDER TO REPLY TO THAT QUESTION IT IS NECESSARY TO CONSIDER WHETHER SUCH A SITUATION FALLS WITHIN THE ' SCOPE OF APPLICATION OF THIS TREATY ' , WITHIN THE MEANING OF ARTICLE 7 OF THE EEC TREATY . IT IS TRUE THAT TEACHERS AT THE EUROPEAN SCHOOL MAY BE REGARDED AS WORKERS WITHIN THE MEANING OF ARTICLE 48 OF THE EEC TREATY WHO , WHERE THEY ARE EMPLOYED IN A SCHOOL SITUATED IN ANOTHER MEMBER STATE , HAVE MADE USE OF THEIR RIGHT TO FREE MOVEMENT WITHIN THE COMMUNITY . THAT IS HOWEVER NOT THE CASE WITH REGARD TO A TEACHER WHO IS A NATIONAL OF THE MEMBER STATE IN WHICH THE EUROPEAN SCHOOL IN QUESTION IS SITUATED AND WHO HAS NOT MOVED WITHIN THE COMMUNITY TO TAKE UP A POST WITH THAT SCHOOL .
55 AS THE COURT HAS ALREADY HELD IN ITS JUDGMENTS OF 28 MARCH 1979 ( CASE 175/78 SAUNDERS ( 1979 ) ECR 1129 ) AND OF 27 OCTOBER 1982 ( JOINED CASES 35 AND 36/82 MORSON AND JHANJAN ( 1982 ) ECR 3723 ), THE PRINCIPLE OF NON-DISCRIMINATION ENSHRINED IN ARTICLE 7 OF THE EEC TREATY , TOGETHER WITH THE SPECIFIC EXPRESSION OF THAT PRINCIPLE IN ARTICLE 48 , CANNOT BE APPLIED TO SITUATIONS WHICH ARE WHOLLY INTERNAL TO A MEMBER STATE AND WHICH ARE IN NO WAY CONNECTED TO ANY SITUATIONS ENVISAGED BY COMMUNITY LAW .

57 MR HURD ALSO REFERRED TO THE GENERAL PRINCIPLES OF COMMUNITY LAW , AND IN PARTICULAR THE PRINCIPLES OF THE PROTECTION OF LEGITIMATE EXPECTATIONS , ESTOPPEL AND COMMUNITY SOLIDARITY , FROM WHICH IT IS , IN HIS VIEW , CLEAR THAT THE UNITED KINGDOM IS BOUND TO RESPECT THE 1957 DECISION .
58 IN THAT RESPECT IT IS SUFFICIENT TO POINT OUT THAT THE PRINCIPLES RELIED ON BY MR HURD DO NOT HAVE , IN A CASE SUCH AS THIS , ANY INDEPENDENT EXISTENCE OUTSIDE THE OBLIGATION WHICH ARTICLE 5 OF THE EEC TREATY IMPOSES ON MEMBER STATES . AS REGARDS LEGITIMATE EXPECTATIONS , IT SHOULD BE NOTED THAT BY REASON OF THE APPLICATION OF ARTICLE 24 ( 2 ) OF THE REGULATIONS FOR MEMBERS OF THE TEACHING STAFF , THE FINANCIAL
