In (1) Clearlake Shipping Pte Ltd and (2) Guvnor Singapore Pte Ltd v Xiang Da Marine Pte Ltd  EWHC 2284 (Comm), the English High Court continued anti-suit injunctions (previously obtained "without notice") restraining the owner of a vessel from bringing/continuing (third party) claims in the Singaporean Courts:
against the charterer of the vessel which, like the owner, was party to a charterparty and letters of indemnity containing (differently-worded) jurisdiction clauses in favour of the English Courts; and against a sub-charterer which had no contractual relationship, and thus no jurisdiction agreement, with the owner. As regards the claims against the charterer, this was because the English jurisdiction agreements between it and the owner should be interpreted consistently where possible - in this case as exclusive clauses - and, as such, they should be enforced by means of an anti-suit injunction on the "contractual basis" in the absence of any strong reasons to the contrary.

In view of those decisions, the Judge declined to decide whether the charterer was itself entitled to an anti-suit injunction in respect of the Singaporean claims against the sub-charterer:
