RIGHT RECOGNIZED UNDER THIS PRINCIPLE TO EMPLOYED PERSONS AND TO MEMBERS OF THEIR FAMILIES TO REMAIN WITHIN THE TERRITORY OF A MEMBER STATE IN WHICH THE EMPLOYED PERSON WAS EMPLOYED UNDER THE CONDITIONS DETERMINED BY REGULATION NO 1251/70 OF THE COMMISSION OF 29 JUNE 1970 ( OJ ENGLISH SPECIAL EDITION 1970 ( II ), P . 402 ).
18 FURTHERMORE , THE OBLIGATION TO ENSURE THAT A HANDICAPPED ADULT CHILD RECEIVES TREATMENT EQUAL TO THAT ACCORDED TO THE NATIONALS OF THE STATE IN WHICH HE RESIDES IS LAID DOWN IN OTHER PROVISIONS OF COMMUNITY LAW RELATING TO FREEDOM OF MOVEMENT FOR WORKERS .
19 ARTICLE 10 ( 1 ) ( A ) OF REGULATION NO 1612/68 OF THE COUNCIL OF 19 OCTOBER 1968 ( OJ ENGLISH SPECIAL EDITION 1968 ( II ), P . 475 ) PROVIDES THAT THE RIGHT TO INSTALL ONESELF IN A MEMBER STATE WITH A WORKER WHO IS EMPLOYED THERE ALTHOUGH A NATIONAL OF ANOTHER MEMBER STATE APPLIES NOT ONLY TO THOSE DESCENDANTS OF SUCH A WORKER WHO ARE UNDER THE AGE OF 21 YEARS BUT ALSO TO THOSE WHO ARE ' DEPENDANTS ' .
20 ARTICLE 7 ( 2 ) OF THE SAME REGULATION PROVIDES THAT A WORKER WHO IS A NATIONAL OF A MEMBER STATE SHALL , IN THE TERRITORY OF ANOTHER MEMBER STATE , ENJOY ' THE SAME SOCIAL AND TAX ADVANTAGES AS NATIONAL WORKERS ' .
21 IN THE LIGHT OF THE EQUALITY OF TREATMENT WHICH REGULATION NO 1612/68 SEEKS TO BRING ABOUT AND TAKING ACCOUNT OF THE PROVISIONS OF THAT REGULATION AS A WHOLE , THE MATTERS COVERED BY ARTICLE 7 ( 2 ) MUST BE DEFINED IN SUCH A WAY AS TO INCLUDE EVERY SOCIAL AND TAX ADVANTAGE , WHETHER OR NOT LINKED TO A CONTRACT OF EMPLOYMENT , SUCH AS AN ALLOWANCE FOR HANDICAPPED ADULTS WHICH IS AWARDED BY A MEMBER STATE TO ITS OWN NATIONALS UNDER LEGISLATION WHICH GIVES A LEGALLY PROTECTED RIGHT THERETO .
22 THE ANSWER TO THE QUESTION REFERRED MUST THEREFORE BE THAT PURSUANT TO REGULATION NO 1408/71 OF THE COUNCIL OF 14 JUNE 1971 , NATIONAL LEGISLATION WHICH , IN A MEMBER STATE , GIVES A LEGALLY PROTECTED RIGHT TO AN ALLOWANCE FOR HANDICAPPED ADULTS TO THE NATIONALS OF THAT STATE WHO RESIDE THERE ALSO APPLIES TO A HANDICAPPED ADULT NATIONAL OF ANOTHER MEMBER STATE WHO HAS NEVER WORKED IN THE STATE WHICH ADOPTED THE LEGISLATION IN QUESTION BUT WHO RESIDES THERE AND IS DEPENDANT UPON HIS FATHER WHO IS EMPLOYED THERE AS A WORKER WITHIN THE MEANING OF THE SAID REGULATION .
