The Brussels I Recast Regulation entitles business actors to agree on which court(s) will have jurisdiction but restricts the effectiveness of such jurisdiction agreements to disputes ‘which have arisen, or which may arise, in connection with a particular legal relationship’. This article fills a gap in the academic literature by examining the content and implications of this necessary connection (proximity) between the claim and the legal relationship between the parties. First, it characterises claim proximity as a question of party autonomy by distinguishing it from the subject matter of the jurisdiction agreement, which is an issue of contract interpretation. Second, it scrutinises the foreseeability test which has been frequently used by the CJEU in order to determine claim proximity, highlighting its main operational aspects. Building on both theoretical considerations and some cases where the foreseeability test has been used by domestic courts, this article provides clarifications about the scope, the proper functioning and the limits of such a test in order to raise awareness regarding the difficulties that may arise in its use in court to determine claim proximity and therefore assess jurisdiction.
