Discretional elements in the Brussels Ia Regulation

Following continental European traditions, the Brussels Ia Regulation forms a rigid regime of mandatory heads of jurisdiction, generally not providing jurisdictional discretion. Nonetheless, to some limited extent, the Brussels regime includes discretional elements, in particular when it comes to lis pendens (see Articles 30, 33 and 34 of Brussels Ia). Reconsidering the strong scepticism towards forum non conveniens stipulated by the CJEU in its Owusu case, the fundamental question arises whether a substantial form of discretion concerning jurisdictional competence might be (in)compatible with the core principles of the Brussels regime.
