The subject of Anti-Suit Injunctions in International Arbitration is well described in the introduction to this publication. It is a timely and serious subject. The threats to and breaches of the efficacy, the integrity, and in some cases the very viability of international arbitration are profound.

Yet, the anti-suit enjoinder of international arbitration is a phenomenon that has generated too little consideration, still less confrontation, and still less cure. Such case law as may be found appears inconclusive. While the issuance of anti-suit injunctions of the arbitral process by national courts is part of State practice in the perspective of international law, that practice is too episodic and incoherent to give rise to rules in which the international community has acquiesced. This is particularly so because that practice appears to violate conventional and customary international law, international public policy and the accepted
principles of international arbitration.

The author wishes to thank the general counsel of the Permanent Court of Arbitration, Mrs. Judy Freedberg, and the assistant legal counsel of the PCA, Mr. Devashish Krishan, for their research assistance.

There have been multiple effective enjoinders of international arbitral recourse, but the legality of those enjoinders remains very much in question. In a few instances, the enjoined arbitral tribunals have nevertheless proceeded to render awards. Those are exceptional cases. Scholarly analysis of the subject of
anti-suit injunctions in respect of arbitration is surprisingly scarce.
