Amcor Ltd v Barnes (Costs Ruling)

In the case of Amcor Ltd v Barnes, the parties were involved in a complex legal dispute concerning counterclaims and cross-claims, which were ultimately heard separately from the trial of the main proceeding. The dispute primarily revolved around the allocation of costs, particularly in relation to the counterclaim and cross-claim, and whether these costs should be awarded on an indemnity basis. The court also needed to determine whether the defendants' rejection of a Calderbank offer was unreasonable, given the offer's lack of clarity and detail, and whether the plaintiffs' costs on the counterclaim should be apportioned to reflect their partial success.

The legal issues before the court included the court's discretion in awarding costs when a counterclaim and cross-claim are heard separately, the appropriate treatment of a lapsed Calderbank offer, and the apportionment of costs for a party who achieved partial success in their claims. The court had to balance the principles that costs generally follow the event with the need to consider the partial success achieved by the plaintiffs. The court was also required to decide whether the defendants' failure to accept the Calderbank offer was unreasonable, considering the offer's lack of clarity and detail.

The court found that it was not unreasonable for the defendants to reject the Calderbank offer due to its lack of clarity and detail. The court further held that the plaintiffs' costs on the counterclaim should be apportioned to reflect their partial success. In making this decision, the court considered the significant resources and efforts expended by both parties in dealing with the numerous OME jobs claimed as breaches. The court opted for a single order to apportion the plaintiffs' costs on the counterclaim, rather than approaching the costs by individual issues, as this would facilitate easier taxation of the costs.

The court made a single order apportioning the plaintiffs' costs on the counterclaim and did not make a special costs order. This decision was based on the court's discretion to balance the need for fairness with the principle that costs generally follow the event, taking into account the mixed success of the parties in their respective claims.
