Mount Isa Mines Ltd v The Ship “Thor Commander” (No 2)

Mount Isa Mines Ltd v The Ship “Thor Commander” (No 2) was a case brought before the Federal Court of Australia. The primary dispute was whether Mount Isa Mines Ltd was entitled to an award of indemnity costs after rejecting a settlement offer made by The Ship “Thor Commander” (referred to as MarShip). The case arose from a dispute over a salvage award and the costs associated with the litigation.

The court had to determine whether Mount Isa Mines Ltd's rejection of MarShip's settlement offer was unreasonable or imprudent, which would entitle Mount Isa Mines Ltd to costs on an indemnity basis. This required an analysis of the factors that may indicate an unreasonable refusal of a settlement offer, including the stage of the proceedings, the time allowed for consideration, the extent of the compromise offered, the offeree's prospects of success, the clarity of the terms of the offer, and whether the offer foreshadowed an application for indemnity costs.

The court held that, despite Mount Isa Mines Ltd's offer being less favourable than its eventual outcome, it was not imprudent or unreasonable for MarShip to reject the offer, given the complexities of the case. The court balanced the promotion of settlement of litigation against the right of parties to resort to the court to resolve their differences, and concluded that MarShip was entitled to reject the offer and proceed to trial.

The court found that MarShip was not liable to pay Mount Isa Mines Ltd's costs on an indemnity basis, given that the rejection of the offer was not plainly unreasonable. The decision emphasised that the rejection of a settlement offer on terms more favourable than the eventual outcome does not automatically lead to an order for indemnity costs. Instead, the applicant must show that the rejection of the offer was imprudent or plainly unreasonable.
