ILS International Law and Practice Course 2026 | May – November 2026, Sydney and Online
Session 2 – Amanda Lees
Session 2:
International Arbitration and multiple proceedings: anti-suit injunctions, anti-arbitration injunctions and transnational issue estoppel
This presentation will examine the tools used by both tribunals and courts to address the multiplicity of proceedings where there is an arbitration agreement.
Amanda Lees, international arbitrator and counsel, will look at when it is appropriate for courts and tribunals to issue anti-suit injunctions against a party to an arbitration agreement pursuing litigation and conversely when it is appropriate for a court to issue an anti-arbitration injunction. In particular, Amanda Lees will look at the competing anti-arbitration injunctions and anti-suit
injunctions in India and Singapore in MSA Global LLC (Oman) v Engineering Projects (India) Ltd and Anupam Mittal v Westbridge Ventures II Investment Holdings.
Often these tools are used in what has been described as “an enforcement war” after an award has been issued. In this context Amanda Lees will also examine the doctrine of transnational issue estoppel and its use to prevent the re-litigation of issues during enforcement of arbitration awards.
