International bodies have started addressing the problem of cross-border insolvency of corporate groups fairly recently. The United Nations Commission on International Trade Law has adopted a set of recommendations and the European Commission may tackle the matter in the near future, in the process of revising the European Insolvency Regulation (the ‘Regulation’). It is, therefore, timely to evaluate major proposals for the Regulation's amendment regarding groups, suggested by INSOL Europe. The paper critically evaluates the proposals regarding coordination of group cases and the concept of substantive consolidation. This evaluation takes account of both the variety of possible group structures and the goals the insolvency regime would aim to achieve.
