Boomerang Investments Pty Ltd v Padgett (Costs of the Liability Phase)

Boomerang Investments Pty Ltd brought an action against Padgett and others, seeking various remedies in the Federal Court. The case revolved around disputes concerning contractual obligations and alleged breaches. Following a partial success at trial, the matter turned to the issue of costs, specifically the liability phase of the proceedings. The court was tasked with determining the appropriate approach to assessing costs given the partial success of the Applicants and the various responses and counterclaims from the Respondents.

The court considered three main legal issues: the appropriate method for assessing costs in light of the Applicants' partial success, the basis on which costs should be determined (party and party or indemnity), and the appropriate measure of any applicable discounts. The court needed to balance the principle that costs should follow the event with the realities of partial success and the conduct of the parties throughout the proceedings.

In its decision, the court opted for a party-by-party assessment of costs, considering the conduct and success of each party on individual issues. It determined that the costs should be assessed on a party and party basis rather than an indemnity basis, given the nature of the partial success. The court also set appropriate discount rates for the taxed costs, taking into account the complexity and duration of the proceedings. Ultimately, the court ordered that the First and Second Respondents pay 50% of the Applicants’ costs, the Fourth Respondent pay 47.5%, and the Applicants pay 90% of the Third Respondent’s costs.
