Gilsan v Optus [No 4]

The matter involved a dispute between Gilsan and Optus, with Gilsan bringing a claim for copyright infringement and Optus defending the claim. The dispute was before the Federal Court of Australia. The case reached the court on the issue of costs apportionment and indemnity costs.

The central legal issues addressed by the court involved whether the costs apportionment should reflect the success and failure of the parties on particular issues, whether the results of cross-claims and subsequent judgments should be considered in the apportionment, and whether indemnity costs should be awarded. The court also examined whether an oral Calderbank offer was effective and if subsequent judgments would interrupt the effect of the indemnity costs.

The court ruled that the apportionment of costs should reflect the parties' success and failure on specific issues, and that the results of cross-claims and subsequent judgments should be included in the apportionment. The court held that indemnity costs should be awarded based on an oral Calderbank offer, but noted that subsequent judgments would not interrupt the effect of the indemnity costs. The court found no question of principle in the case.

The court ordered that the costs apportionment would be made in accordance with the principles outlined, with specific reference to the success and failure of the parties on particular issues, and the inclusion of cross-claims and subsequent judgments in the apportionment. The court also awarded indemnity costs based on the effective Calderbank offer, ensuring that subsequent judgments would not affect the indemnity costs.
