The Owners of the Motor Vessel “Iran Amanat” v KMP Coastal Oil Pte Ltd

The Owners of the Motor Vessel “Iran Amanat” (the Owners) appealed to the High Court of Australia against a decision concerning the arrest of their vessel. The dispute arose from an action in rem brought by KMP Coastal Oil Pte Ltd (KMP) against the "Iran Amanat" in relation to a general maritime claim. The central issue was whether the Owners, as the shipowner, qualified as a "relevant person" for the purposes of the *Admiralty Act 1988* (Cth) in circumstances where KMP sought to arrest the "Iran Amanat" as a surrogate or sister ship.

The High Court was required to determine whether the *Admiralty Act 1988* permitted the arrest of a vessel in rem when the claim was against a different vessel owned by the same entity, and whether the shipowner of the arrested vessel was a "relevant person" for the purposes of establishing jurisdiction under the Act. Specifically, the Court considered the interpretation of "relevant person" in the context of general maritime claims and the arrest of surrogate or sister ships.

The Court reasoned that the *Admiralty Act 1988* allows for the arrest of a surrogate or sister ship if the owner of that ship is the person liable in personam in respect of the cause of action. Gleeson CJ, McHugh, Gummow, Kirby and Hayne JJ held that the Owners, being the owners of the "Iran Amanat", were indeed the relevant persons against whom KMP had a claim in personam, even if the original cause of action related to a different vessel. The appeal was accordingly dismissed with costs.
