Global perspectives on parallel proceedings and related actions

Wednesday 7 October (1615 - 1730)

Committee(s)

Litigation Committee (Lead)
Hague Conference on Private International Law Subcommittee

Description

As cross-border litigation becomes increasingly complex, courts worldwide face growing challenges in managing parallel proceedings and related actions across multiple jurisdictions. This session will examine the evolving international framework for addressing these issues, with particular focus on the Hague Conference's ongoing work toward a new convention on parallel proceedings.

The session will explore how different legal systems approach the coordination of simultaneous litigation, including:

•            the development and potential impact of the proposed new Hague Convention on parallel proceedings, examining key provisions and implementation challenges;
•            regional frameworks such as the Brussels I and Lugano regimes in Europe, which employ lis pendens and related actions doctrines to prevent conflicting judgments;
•            common law approaches, including the US Colorado River abstention doctrine and forum non conveniens principles; and
•            practical considerations for counsel managing multi-jurisdictional disputes, including strategic implications of competing proceedings and coordination mechanisms.
