AbstractThe legislation of the European Union has addressed the private international law aspects of civil and commercial matters and those of insolvency cases separately. While the Brussels Ibis Regulation (and its predecessors) focuses on “classic” civil of commercial cases, insolvency proceedings are subject to the (recast) Insolvency Regulation. However, the close interference between the two related areas of law—commercial and insolvency—results in a category of cases that are commercial and contentious in nature, and so they would tend to gravitate towards the Brussels regime, but yet they are so closely connected to the insolvency proceedings that justifies a special approach. This article focuses on the question of international jurisdiction regarding these “annex actions” in the context of the EU law. It will attempt to explore the historical roots of the current provisions and the evolution of both the European legislation and the relevant case law. The examination of this progression provides a better understanding of the current legislation and answers some questions apparently left open in the recast Insolvency Regulation.
