Mackenzie v VicRoads

The case of Mackenzie v VicRoads was heard by the Supreme Court of Victoria, where the plaintiff, Mackenzie, sought an interlocutory injunction against VicRoads, the defendant, to prevent the continuation of a road project. The plaintiff alleged that the project would cause significant environmental damage and that there were deficiencies in the Environment Effects Statement and the Minister’s assessment. The primary legal issues before the court were whether there was a serious question to be tried, whether the balance of convenience favoured the grant of an injunction, and whether the precautionary principle had been complied with.

The court examined the Environment Effects Statement and the Minister’s assessment for any deficiencies that would warrant halting the project. It considered whether the plaintiff had demonstrated a serious question to be tried regarding the environmental impacts and the adequacy of the assessments. Additionally, the court assessed the balance of convenience, weighing the potential harm to the environment against the benefits of the road project. The court also considered whether VicRoads had adhered to the precautionary principle, which requires taking preventive action in the face of environmental threats when scientific evidence is inconclusive.

In its reasoning, the court found that the plaintiff had not demonstrated a serious question to be tried as the evidence provided did not sufficiently challenge the adequacy of the Environment Effects Statement and the Minister’s assessment. The court also determined that the balance of convenience did not favour granting an injunction, as the harm to the public from halting the project outweighed the potential environmental damage. Furthermore, the court held that the precautionary principle was not breached as VicRoads had acted on the available evidence. The court also noted that procedural fairness was observed in the assessments and that no viable undertaking as to damages had been provided by the plaintiff.

The court dismissed the application for an interlocutory injunction, ruling that VicRoads could continue with the road project. The court found that the plaintiff had not met the necessary criteria to warrant a temporary halt to the project, and therefore, the application was unsuccessful.
