Staska v General Motors-Holden's Pty Ltd

Maria Staska, the appellant, appeals against the decision of the High Court of Australia in relation to the redemption of her late husband's employer's liability for weekly payments under the Workmen's Compensation Act, 1932-1966 (S.A.). The employer, General Motors-Holden's Pty Ltd, argues that the employer's liability should be based on the total liability of 2,600 pounds, which was in force at the time of the injury in 1956. Staska contends that the liability should be based on the total liability of 6,000 pounds, which was introduced by an amending Act of 1965. The central issue in this appeal is which figure of total liability should be taken as the basis for assessing the redemption price, and whether the 1965 amending Act applies to injuries that occurred before its enactment.

The Court considered the relevant statutory provisions, including the Workmen's Compensation Act, 1932-1963, the Workmen's Compensation Amendment Act, 1965, and the Workmen's Compensation Amendment Act, 1966. The Court found that the presumption against retrospective operation of a statute and the statutory history of the Workmen's Compensation Act should be taken into account. The Court also highlighted the difficulties caused by inflation and the importance of legislative patterns.

The Court concluded that the 1965 amending Act did not apply to compensation for past accidents, as it would have been a revolutionary innovation requiring express words or very clear implication. The Court found that the new section 28a of the principal Act, inserted by the Act of 1965, only effected a partial innovation, applicable only to a special class of workmen. The Court further determined that the Act of 1966 brought about an extensive modification of the previous system but did not affect the total liability under section 18(3) of the principal Act.

Based on the Court's reasoning, the total liability to be taken as the basis for redemption is 2,600 pounds ($5,200) and not 6,000 pounds ($12,000). The decision of the majority of the High Court of Australia should be affirmed, and the appeal should be dismissed. The appellant must pay the respondents' costs of the appeal.
