Matthews v SPI Electricity Pty Ltd (Ruling No 5)

Matthews and others sought to bring a class action against SPI Electricity Pty Ltd in the Supreme Court of Victoria, under Chapter 4A of the Supreme Court Act 1986 (Vic), concerning claims for electricity pricing and contract breaches. The primary legal issue addressed was whether the use of a sample group member process at trial was appropriate and, if so, how the liability for costs associated with these sample group members should be determined. Specifically, the court needed to decide whether the quantum of the sample group members' claims should be ascertained at the trial stage or left for later determination.

The court ruled that the use of sample group members was permissible under the class action provisions. It held that the quantum of the claims of the sample group members should be determined at the trial stage to provide clarity and finality to the proceedings. This approach ensures that the representative nature of the sample group is maintained and that the trial process is efficient. The court found that determining the quantum of the claims at the trial stage was necessary to allow for the assessment of the representativeness of the sample group and to facilitate the calculation of overall damages.

The decision was that the quantum of the claims of the sample group members should be determined at the trial stage, providing a clear and final resolution to the matter. This ensures that the class action process remains effective and representative, allowing for an accurate assessment of the claims made by the plaintiffs. The court's ruling emphasised the importance of maintaining the integrity of the class action mechanism in the Victorian Supreme Court.
