LAW OF MEMBER STATES A SET OF PROVISIONS INTENDED TO FACILITATE THE EFFECTIVE EXERCISE OF THIS FREEDOM, IN PARTICULAR BY THE MUTUAL RECOGNITION OF PROFESSIONAL QUALIFICATIONS AND THE COORDINATION OF LAWS WITH REGARD TO THE PURSUIT OF ACTIVITIES AS SELF-EMPLOYED PERSONS .
22 THESE DIRECTIVES ALSO HAVE THE TASK OF RESOLVING THE SPECIFIC PROBLEMS RESULTING FROM THE FACT THAT WHERE THE PERSON PROVIDING THE SERVICE IS NOT ESTABLISHED, ON A HABITUAL BASIS, IN THE STATE WHERE THE SERVICE IS PERFORMED HE MAY NOT BE FULLY SUBJECT TO THE PROFESSIONAL RULES OF CONDUCT IN FORCE IN THAT STATE .
23 AS REGARDS THE PHASED IMPLEMENTATION OF THE CHAPTER RELATING TO SERVICES, ARTICLE 59, INTERPRETED IN THE LIGHT OF THE GENERAL PROVISIONS OF ARTICLE 8 ( 7 ) OF THE TREATY, EXPRESSES THE INTENTION TO ABOLISH RESTRICTIONS ON FREEDOM TO PROVIDE SERVICES BY THE END OF THE TRANSITIONAL PERIOD, THE LATEST DATE FOR THE ENTRY INTO FORCE OF ALL THE RULES LAID DOWN BY THE TREATY .
24 THE PROVISIONS OF ARTICLE 59, THE APPLICATION OF WHICH WAS TO BE PREPARED BY DIRECTIVES ISSUED DURING THE TRANSITIONAL PERIOD, THEREFORE BECAME UNCONDITIONAL ON THE EXPIRY OF THAT PERIOD .
25 THE PROVISIONS OF THAT ARTICLE ABOLISH ALL DISCRIMINATION AGAINST THE PERSON PROVIDING THE SERVICE BY REASON OF HIS NATIONALITY OR THE FACT THAT HE IS ESTABLISHED IN A MEMBER STATE OTHER THAN THAT IN WHICH THE SERVICE IS TO BE PROVIDED .
26 THEREFORE, AS REGARDS AT LEAST THE SPECIFIC REQUIREMENT OF NATIONALITY OR OF RESIDENCE, ARTICLES 59 AND 60 IMPOSE A WELL-DEFINED OBLIGATION, THE FULFILMENT OF WHICH BY THE MEMBER STATES CANNOT BE DELAYED OR JEOPARDIZED BY THE ABSENCE OF PROVISIONS WHICH WERE TO BE ADOPTED IN PURSUANCE OF POWERS CONFERRED UNDER ARTICLES 63 AND 66 .
27 ACCORDINGLY, THE REPLY SHOULD BE THAT THE FIRST PARAGRAPH OF ARTICLE 59 AND THE THIRD PARAGRAPH OF ARTICLE 60 HAVE DIRECT EFFECT AND MAY THEREFORE BE RELIED ON BEFORE NATIONAL COURTS, AT LEAST IN SO FAR AS THEY SEEK TO ABOLISH ANY DISCRIMINATION AGAINST A PERSON PROVIDING A SERVICE BY REASON OF HIS NATIONALITY OR OF THE FACT THAT HE RESIDES IN A MEMBER STATE OTHER THAN THAT IN WHICH THE SERVICE IS TO BE PROVIDED .
