When you suffer a workplace injury, it is tempting to file multiple claims across different legal pathways to maximise your chances of success. However, the decision in Mastrangeli v Workers’ Compensation Regulator [2025] QIRC 263 highlights why this strategy can completely backfire. In this case the Queensland Industrial Relations Commission (“QIRC”) demonstrated the severe consequences of pursuing parallel actions for the exact same workplace issues.
The Risk of Duplication
In Mastrangeli, the applicant brought claims based on the same facts through both anti-discrimination and workers’ compensation pathways. The workers’ compensation claim was rejected by WorkCover and the Regulator on review and was taken to the QIRC but was put on hold pending the outcome of the discrimination claim. Following the failure of the discrimination claim, the Commission dismissed the subsequent workers’ compensation appeals. Pursuant to legislation like the Industrial Relations Act 2016 (Qld), tribunals can dismiss applications where the underlying issues have already been addressed in a prior proceeding, preventing the re-litigation of the same facts.
Why Multiple Claims Backfire
- Issue Estoppel and Res Judicata: These principles mean that legal findings from a prior proceeding are binding, preventing a “second bite of the cherry” if the first claim fails.
- Public Interest Dismissals: Courts aim to prevent the burden of repetitive litigation regarding the same events, making parallel actions a high-stakes risk.
Streamline Your Strategy Launching scattered legal actions can lead to a domino effect, where a loss in one arena destroys the others. Rather than pursuing multiple, overlapping claims, focus on a cohesive legal strategy. If you are facing a workplace dispute, seek professional advice to map out the most effective approach to any claim and the most appropriate course of action for you.
