Trevorrow v State of South Australia (No 6)

In the case of Trevorrow v State of South Australia (No 6), the plaintiff sought an award of interest on a portion of the damages sum pursuant to section 30C of the Supreme Court Act 1935 (SA). The dispute revolved around the recoverability of interest on damages and the appropriate rate and period for which interest should be awarded. The court was tasked with examining the purpose behind the award of interest, the retrospective application of section 30C, and the discretionary nature of the provision. Additionally, the court needed to determine the relevant time period for the calculation of interest, the role of inflation in setting the interest rate, and whether a lump sum award would be more appropriate than interest.

The court deliberated on the statutory provision which allows for the award of interest on damages, focusing on its intent and scope. It considered the retrospective effect of section 30C, which was introduced after the plaintiff's claim had been established, and examined whether such retrospective application was permissible. The discretionary nature of the provision meant that the court had to weigh various factors in determining whether interest should be awarded and, if so, the appropriate amount and rate. The court also explored the relevance of inflation in setting the interest rate and the significance of the time period from which interest should accrue. Finally, the court assessed whether a lump sum payment would serve as a better alternative to ongoing interest payments.

After careful consideration of the statutory language, the purpose of the interest award, and the specific circumstances of the case, the court determined that interest should be awarded in accordance with section 30C. The court found that the retrospective application of the section was appropriate, and it exercised its discretion to award interest. The court set the interest rate and the period from which interest would run, taking into account inflation and the specific facts of the case. Ultimately, the court ruled in favour of the plaintiff and awarded interest as damages, considering the appropriate lump sum award.

The court made an order awarding interest to the plaintiff on the portion of the damages sum in accordance with section 30C of the Supreme Court Act 1935 (SA). The court specified the interest rate, the period from which interest would accrue, and the total amount of interest to be awarded. The court also directed the defendant to pay the plaintiff's costs associated with the claim for interest.
