Unsworth v Tristar Steering and Suspension Australia Ltd

Unsworth brought proceedings against Tristar Steering and Suspension Australia Limited, alleging that Tristar contravened the Workplace Relations Act 1996 by not dismissing certain employees. The crux of the applicant's argument was that Tristar retained employees beyond their need, specifically to avoid making substantial severance payments due to the employees' length of service. Tristar defended on the grounds that the retention of these employees was based on their skills and the potential for work in remanufacturing and overseas joint ventures. The central legal issue before the court was whether Tristar's conduct constituted discrimination or victimization under the Act. Specifically, it had to be determined if Tristar's retention of certain employees was motivated by a prohibited reason, as defined in the Act.

The court found that while the length of service was indeed a factor in the decision not to dismiss certain employees, this did not establish a prohibited reason under the Act. The court reasoned that the retention was primarily due to the potential for remanufacturing work and overseas ventures, which were genuine pursuits. Moreover, the court held that there was no causal link between any adverse impact on the employees and the alleged prohibited reason. Consequently, the court concluded that Tristar's actions did not contravene the Act.

Based on the reasoning and findings, the court dismissed Unsworth's case. No further consideration was given to the position of other employees not covered by the Certified Agreement, and no order regarding costs was made. The court found that the proceeding was not instituted vexatiously or without reasonable cause but ultimately determined that there was no basis for the relief claimed.
