Carolyn Philips (nee Durrand) v Tower Australia Ltd

The case of Carolyn Philips (nee Durrand) against Tower Australia Ltd was heard in the Federal Court of Australia. Ms Durrand, the plaintiff, sought a declaration that the defendant, Tower Australia Ltd, a health insurer, owed her an amount of interest on unpaid disability income protection insurance payments. The underlying dispute arose from the defendant's refusal to pay additional interest on disability income protection benefits that were owed to Ms Durrand after she had been injured in a workplace accident. The primary issue before the court was determining the appropriate rate of interest that should be applied to the period for which the insurance payments were delayed.

The court was required to decide whether the statutory interest under section 58 of the Insurance Contracts Act 1984 (Cth) or the common law rate of interest was applicable. Ms Durrand argued that the statutory interest rate should apply from the date it was unreasonable for the insurer to withhold payment, while Tower Australia Ltd contended that the common law rate was the appropriate measure. The court had to consider the meaning of the phrase "unreasonable for the insurer to have withheld payment" and whether it referred to the date when the insurer first became aware of the need to pay or the date when payment was actually made.

The court found that the statutory interest rate applied from the date when it was unreasonable for the insurer to withhold payment, which was the date when the insurer first became aware of the need to pay. The court reasoned that this interpretation was consistent with the purpose of the statutory interest provisions, which was to provide a remedy for the delay in payment by the insurer. The court held that the statutory interest rate should be applied from the date when the insurer first became aware of the need to pay, rather than the date when payment was actually made. The decision was based on the legislative intent to compensate the insured for the delay in payment by the insurer. The court's interpretation of the statutory interest provisions ensured that the insured received a fair remedy for the insurer's delay in making the payment. The court ordered Tower Australia Ltd to pay Ms Durrand the statutory interest on the unpaid disability income protection benefits from the date when it was unreasonable for the insurer to withhold payment.
