CONNECTED , AT LEAST INDIRECTLY , WITH AN EMPLOYMENT RELATIONSHIP AND MUST BE GRANTED IN AN AREA WHICH CAN BE SAID TO FALL WITHIN THAT OF SOCIAL AFFAIRS ; THESE CONDITIONS ARE NOT MET IN THIS CASE .
10 THE QUESTION REFERRED BY THE COUR D ' APPEL , LIEGE , MUST BE RESOLVED IN THE LIGHT OF ALL THE PROVISIONS OF THE TREATY AND OF SECONDARY LEGISLATION WHICH MAY BE RELEVANT TO THE PROBLEM .
11 IT MUST BE POINTED OUT THAT ARTICLE 220 , WHICH WAS MENTIONED IN THE QUESTION SUBMITTED BY THE COUR D ' APPEL , IS NOT INTENDED TO LAY DOWN A LEGAL RULE DIRECTLY APPLICABLE AS SUCH , BUT MERELY DEFINES A NUMBER OF MATTERS ON WHICH THE MEMBER STATES ARE TO ENTER INTO NEGOTIATIONS WITH EACH OTHER ' SO FAR AS IS NECESSARY ' .
