Tonicstar Ltd. (Operating As Lloyd's Syndicate 1861) v American Home Assurance Company

An anti-suit injunction may be granted where foreign proceedings are unconscionable, oppressive or vexatious and threaten the legitimate interests of proceedings in England. England must be the natural forum, although that is necessary but not sufficient. The court must also consider all the circumstances, including the interests of justice and comity. Parallel proceedings may justify relief where they create a risk of conflicting judgments or an unmerited race to establish preclusive effects. The remedy remains exceptional and discretionary.

The claimants sought continuation of an anti-suit injunction restraining American Home Assurance Company from pursuing a New York petition to compel arbitration and restrain proceedings in England. The dispute arose from a facultative excess of loss reinsurance contract placed in the Lloyd’s market. The arbitration clause did not specify the seat of arbitration.

Proceedings had first been commenced in England. American Home later applied in England for a stay under section 9 of the Arbitration Act 1996, but subsequently presented the New York petition. The central issues were whether England was the natural forum, whether the New York proceedings were oppressive or vexatious, and whether the interests of justice required an injunction.

1. Natural forum. England was the natural forum. The reinsurance was placed through Lloyd’s brokers, used Lloyd’s wording, was to be performed and administered substantially in London, and the relevant misrepresentations and non-disclosures occurred there. The proper law of the reinsurance and arbitration agreement was English law. The location of American Home’s documents and witnesses in New York did not displace the centre of gravity of the dispute.
2. Unconscionable conduct. The principles summarised by Rix LJ in Glencore International v Exeter Shipping [2002] CLC 1090 were applied. The foreign conduct had to be unconscionable, including oppressive or vexatious conduct or interference with the due process of the English court. There had to be a clear need to protect English proceedings.
3. American Home’s decision to make an application under section 9 of the Arbitration Act 1996 and then, without prior notice, present the New York petition was oppressive. It sought to pre-empt this court’s determination of whether the arbitration clause applied and, if so, where the arbitration should be seated.
4. The court adopted the approach in General Star International Indemnity Ltd v Stirling Cooke Brown Reinsurance Brokers Ltd [2003] EWHC 3 (Comm) 314, Airbus Industrie v Patel [1999] 1 AC 119 and Pathe Screen Entertainment Limited v Handmade Films (Distributors) Limited [11 July 1989]. Natural forum alone was insufficient. The court had to exercise its discretion in the interests of justice, with caution and regard to comity. Concurrent proceedings risked conflicting judgments and an unjust race to judgment, as discussed in Abdin v Daver and Dupont No 1.
5. The claimants’ procedural shortcomings, including the technical question concerning Tonicstar’s standing, did not justify refusing relief. The injunction was continued until further order.
