Illawong Village P/L v State Bank of NSW Limited

The appellant, Illawong Village Pty Ltd, a company involved in the construction and operation of a shopping centre, appealed a decision concerning interest charged by the respondent, State Bank of NSW Limited, on a loan. Illawong claimed it was overcharged interest during a period after the initial term of the loan expired but before the loan was fully repaid, a period referred to as the "limbo period," and sought damages. The dispute centred on whether the interest rate charged by the Bank during this limbo period exceeded what it was contractually entitled to charge.

The court was required to determine whether a continuing agreement existed regarding the relevant interest rate applicable to the Bank's loan, and if so, whether that agreement extended to the limbo period. A key legal issue was whether the source of this agreement was the original mortgage documents or a subsequent security interest taken over property acquired later by Illawong.

The court reasoned that the facility letter, while forming the basis for the security documentation, did not govern the charging of interest until the loan was repaid. The 1990 mortgages were given in fulfilment of an obligation under the 1988 Charge to provide security over subsequently acquired land. These 1990 mortgages were supplementary to the earlier 1988 securities. The court concluded that the parties intended for the 1988 securities to govern the charging of interest beyond the initial three-year term of the facility, even if a specific agreement on the rate was not reached. In such circumstances, the 1988 securities entitled the respondent to charge interest at a rate determined by its decision.

The appeal was dismissed with costs.
