This one long overdue – I am adding it to the blog for completeness’ sake. C‑649/16 Valach was held end of December 2017. The CJEU relies heavily on Tunkers and recital 6 of the (old) Insolvency Regulation: the regulation should be confined to provisions governing jurisdiction for opening insolvency proceedings and judgments which are ‘delivered directly on the basis of the insolvency proceedings and are closely connected with such proceedings’: the latter two criteria guide the CJEU.
In the case at issue, the action for liability at issue in the main proceedings is the direct and inseparable consequence of the performance by the committee of creditors, a statutory body established by Slovak law when insolvency proceedings are opened, of the task specifically assigned to them by the provisions of national law governing such procedures. Consequently, it is clear that the obligations which form the basis of bringing an action for liability in tort against a committee of creditors, such as that at issue in the main proceedings, originate in rules that are specific to insolvency proceedings (at 35-36).
As for the second criterion, it is the closeness of the link between a court action and the insolvency proceedings that is decisive for the purposes of deciding whether the Brussels I Recast’s insolvency exception is triggered. That is the case here: at 38: in order to ascertain whether the liability of the members of the committee of creditors may be engaged because of the rejection of the restructuring plan, it will be necessary to analyse in particular the extent of that committee’s obligations in the insolvency proceedings and the compatibility of the rejection with those obligations. Such an analysis clearly presents a direct and close link with the insolvency proceedings, and is therefore closely connected with the course of those proceedings.
