Request for a preliminary ruling from the Rechtbank van eerste aanleg West-Vlaanderen in the case Van der Weegen and Pot. Does Article 21(5) of the 1992 Belgian Income Tax Code (WIB 1992), as amended by Article 170 of the Law of 25 April 2014 laying down various provisions, infringe the provisions of Articles 56 TFEU and 63 TFEU and Articles 36 and 40 of the EEA Agreement, inasmuch as the provision in question, although applicable without distinction to domestic and foreign service providers, requires compliance with conditions similar to those included in Article [2] of the Royal Decree implementing the 1992 Income Tax Code (KB/WIB 1992) which are de facto specific to the Belgian market and consequently amount to a serious obstacle to foreign service providers offering their services in Belgium?
