European Union – Jurisdiction. Article 19(2)(a) of Council Regulation (EC) 44/2001 had to be interpreted as meaning that, in the event of proceedings being brought by a member of the air crew, in order to establish the jurisdiction of the court seised, the concept of 'place where the employee habitually carries out his work', within the meaning of that provision, could not be equated with that of 'home base', within the meaning of Annex III to Council Regulation (EEC) 3922/91. Nevertheless, the Court of Justice of the European Union held that it was a significant indicium.
