As I have reported before, English practice is to continue using anti-suit injunctions outside of the Brussels I Regulation, in particular to support arbitration. Recent application was made in Crescendo Maritime, restraining litigation in China. Teare J confirmed among others (per Toepfer v Cargill) that forum non conveniens (Chine was the natural forum for litigation in ordinary) has little relevance in the context of arbitration clauses.
Kennedys have background to the case (essentially, backdating of a shipbuilding contract to avoid newly introduced international rules on tank coatings). The considered use of anti-suit once again underlines the importance of tools of civil procedure to support global arbitration practices.
