The Insurance Company of the State of Pennsylvania v Equitas Insurance Ltd

A claimant that voluntarily brings essentially identical proceedings in England and another jurisdiction will ordinarily obtain a stay of the English proceedings only in special, rare or exceptional circumstances. The court must consider the claimant’s choice to commence both actions and the prejudice to the defendant, and the benefits of a stay must clearly outweigh its disadvantages. An anti-suit injunction may be refused where the foreign proceedings are not vexatious or oppressive, even though the English court is the natural or more appropriate forum. The court may consider detrimental reliance on the impression created by the claimant’s conduct, but modest wasted costs will not alone justify an injunction.

ICSOP brought proceedings in England against EIL concerning alleged Lloyd’s reinsurance of liabilities arising from DBCP claims. During negotiations conducted by reference to the English claim, ICSOP did not disclose that it intended to sue in New York if settlement failed. It subsequently commenced substantially the same proceedings in the United States and applied to stay the English action pending EIL’s jurisdictional and forum applications there. EIL sought an anti-suit injunction restraining the New York proceedings and, alternatively, opposed the stay. The issues were whether London was the appropriate forum, whether ICSOP’s conduct made the New York proceedings vexatious or oppressive, and whether justice required a stay of the English proceedings.

1. Forum. The Commercial Court was the appropriate forum. The reinsurance contracts were overwhelmingly likely to be governed by English law under the applicable conflict rules. That made London preferable for determining contract formation, the underwriters’ participation and percentage lines, the meaning and effect of the reinsurances, and the Part VII transfer. The possible limitation advantage in New York did not outweigh the advantages of having English law decided by the English Commercial Court, with its experience of Lloyd’s reinsurance practice. The court could also favour its own conflict rules.
2. Anti-suit injunction. ICSOP’s conduct was unsatisfactory. It had created the reasonable impression that, if negotiations failed, it would litigate in England. Nevertheless, EIL’s detrimental reliance was insufficiently prejudicial to make the New York proceedings vexatious or oppressive. The claims were essentially the same, the open positions remained relevant, and EIL was still able to address the governing-law arguments. Possible wasted costs were not a sufficient foundation for an injunction.
3. Stay. A claimant who voluntarily starts substantially identical proceedings in two jurisdictions should obtain a stay of the English proceedings only in rare or compelling circumstances. The benefits of a stay must clearly outweigh any disadvantage to the defendant. The reasoning in AG v Arthur Andersen & Co [1989] ECC 224 did not require a stay because the claimant’s conduct and the procedural circumstances were materially different.
4. Both applications failed. ICSOP was required to continue the English action, including EIL’s counterclaim, unless it obtained permission to discontinue or dismiss its English claim.
