Guss v Johnstone

The case of *Guss v Johnstone* concerned a dispute between the appellant, Guss, and the respondent, Johnstone, before the High Court of Australia. The central issue revolved around the interpretation and application of section 139 of the *Motor Accidents Compensation Act 1999* (NSW) (the Act), which deals with the recovery of damages for economic loss in motor accident claims. Guss sought to recover damages for economic loss, but Johnstone argued that Guss was precluded from doing so by the operation of section 139.

The High Court was required to determine whether section 139 of the Act operated to prevent Guss from recovering damages for economic loss, notwithstanding that Guss had not made an election under section 138 of the Act. Specifically, the Court had to consider the relationship between section 138, which provides for an election to claim damages for economic loss, and section 139, which sets out the consequences of such an election. The core legal question was whether section 139 imposed a condition precedent to the recovery of economic loss damages, or whether it merely prescribed the method of calculation and recovery once an election had been made.

Kirby and Callinan JJ, in separate judgments, both found in favour of Guss. Their Honours held that section 139 did not impose an election requirement as a prerequisite to claiming economic loss. Instead, they reasoned that section 139 was concerned with the *method* of calculating and recovering economic loss damages, and that the election provided for in section 138 was a mechanism for choosing between different heads of damage, not a barrier to recovery itself. The Court concluded that Guss was entitled to pursue his claim for economic loss.
