During the revision of the Brussels I Regulation several issues pertaining to the interface between arbitration and the Regulation were discussed. Some of the issues were parallel proceedings and conflicting decisions between courts and between courts and arbitral tribunals and the lack of a uniform rule on the law applicable to the existence and validity of an arbitration agreement. This article examines these issues in order to find out whether they are only European or also inherent in the international regulation of international commercial arbitration. The article examines to which extent these issues have already been addressed in the international regulation. Moreover, the article analyses the issues from a European perspective by analysing the interface between the Brussels I Regulation and arbitration and by looking into the objectives of the EU judicial cooperation in civil matters. Finally, the article looks into what the future might hold for these two issues.
