Question referred

Does the Decree of the Flemish Community of 19 July 1973 (B.S. 6 September 1973) infringe Article 39 of the EC Treaty concerning freedom of movement for workers within the European Union, in that it imposes an obligation on an undertaking situated in the Flemish language region when hiring a worker in the context of employment relations with an international character, to draft all documents relating to the employment relationship in Dutch, on pain of nullity?
