SUCH A FEE IS NOT REQUIRED FROM A NATIONAL OF THAT STATE OR THE SPOUSE OF SUCH A PERSON .
7 IT MUST BE REMEMBERED FIRST OF ALL THAT ARTICLE 7 OF THE TREATY PROHIBITS WITHIN THE SCOPE OF APPLICATION OF THE TREATY , AND WITHOUT PREJUDICE TO ANY SPECIAL PROVISIONS CONTAINED THEREIN , ANY DISCRIMINATION ON GROUNDS OF NATIONALITY .
8 IT IS NOT DENIED IN THIS CASE THAT THE BELGIAN RULES LAY DOWN IN CONNECTION WITH THIS MATTER DIFFERENT TREATMENT FOR BELGIAN NATIONALS AND THE NATIONALS OF OTHER MEMBER STATES . THE NATIONAL COURT IS THEREFORE ASKING WHETHER IN THE CASE OF THE SPOUSE OF AN OFFICIAL OF THE COMMUNITY WHO IS NOT OF BELGIAN OR LUXEMBOURG NATIONALITY THE PAYMENT OF THE ENROLMENT FEE FALLS ' ' WITHIN THE SCOPE OF APPLICATION ' ' OF THE TREATY AND IF SO WHETHER THE FACT THAT OFFICIALS OF THE COMMUNITY WORKING IN BELGIUM ARE EXEMPT FROM PAYMENT OF TAXES TO THE BELGIAN STATE MAY BE RELEVANT IN THAT RESPECT .
9 IN ANSWER TO THAT QUESTION IT MUST BE OBSERVED THAT THE LEGAL POSITION OF OFFICIALS OF THE COMMUNITY IN THE MEMBER STATES IN WHICH THEY ARE EMPLOYED COMES WITHIN THE SCOPE OF THE TREATY ON A DUAL BASIS BY REASON OF THEIR POST WITH THE COMMUNITY AND BECAUSE THEY MUST ENJOY ALL THE BENEFITS FLOWING FROM COMMUNITY LAW FOR THE NATIONALS OF MEMBER STATES IN RELATION TO FREEDOM OF MOVEMENT , FREEDOM OF ESTABLISHMENT AND SOCIAL SECURITY .
10 ARTICLE 48 OF THE TREATY PROVIDES THAT FREEDOM OF MOVEMENT FOR WORKERS SHALL BE SECURED WITHIN THE COMMUNITY BY THE END OF THE TRANSITIONAL PERIOD AT THE LATEST . IT ENTAILS THE ABOLITION OF ANY DISCRIMINATION BASED ON NATIONALITY BETWEEN WORKERS OF THE MEMBER STATES AS REGARDS EMPLOYMENT , REMUNERATION AND OTHER CONDITIONS OF WORK AND EMPLOYMENT .
11 ACCORDING TO BOTH THE LEGISLATIVE PRACTICE OF THE COMMUNITY AND THE ESTABLISHED CASE-LAW OF THE COURT THE RIGHT TO FREE MOVEMENT MUST NOT BE INTERPRETED NARROWLY . AS THE RECITALS IN THE PREAMBLE TO REGULATION NO 1612/68 OF THE COUNCIL STATE , IT CONSTITUTES A FUNDAMENTAL RIGHT OF WORKERS AND THEIR FAMILIES SINCE MOBILITY OF LABOUR WITHIN THE COMMUNITY MUST BE ONE OF THE MEANS BY WHICH THE WORKER IS GUARANTEED THE POSSIBILITY OF IMPROVING HIS LIVING AND WORKING CONDITIONS AND PROMOTING HIS SOCIAL ADVANCEMENT .
12 ACCORDING TO THE FIFTH RECITAL IN THE PREAMBLE TO THE SAME REGULATION THE RIGHT OF FREEDOM OF MOVEMENT , IN ORDER THAT IT MAY BE EXERCISED , BY OBJECTIVE STANDARDS , IN FREEDOM AND DIGNITY , REQUIRES THAT EQUALITY OF TREATMENT SHALL BE ENSURED IN FACT AND IN LAW IN RESPECT OF ALL MATTERS RELATING TO THE ACTUAL PURSUIT OF ACTIVITIES AS EMPLOYED PERSONS AND TO ELIGIBILITY FOR HOUSING , AND ALSO THAT OBSTACLES TO THE MOBILITY OF WORKERS SHALL BE ELIMINATED , IN PARTICULAR AS REGARDS THE WORKER ' S RIGHT TO BE JOINED BY HIS FAMILY AND THE CONDITIONS FOR THE INTEGRATION
