“It follows that the decisive criterion adopted by the Court to identify the area within which an action falls is not the procedural context of which that action is part, but the legal basis thereof. According to that approach, it must be determined whether the right or the obligation which respects the basis of the action finds its source in the common rules of civil and commercial law or in the derogating rules specific to insolvency proceedings.”
“[i]ts effect [i.e. of article 28] is not entirely mechanical. It requires an assessment of the degree of connection, and then a value judgment as to the expediency of hearing the two actions together (assuming they could be so heard) in order to avoid the risk of inconsistent judgments. It does not say that any possibility of inconsistent judgments means that they are inevitably related. It seems to us that the Article leaves it open to a court to acknowledge a connection, or a risk of inconsistent judgments, but to say that the connection is not sufficiently close or the risk is not sufficiently great, to make the action related for the purposes of the Article. Mechanics do not, for once, provide a complete answer.”
