Multiple reports say the NSW government faces legal risk over a planned road-user charge and is being urged to make significant changes to ensure the measure is not struck out by the courts. The suggested approach includes expanding the charge so it applies to more drivers and potentially taxing a broader range of vehicles, rather than limiting it to specific categories. The coverage is framed around the need to adjust the policy design in response to court considerations, implying that aspects of the current plan may not be sufficiently robust to withstand legal scrutiny. While the reports focus on NSW, they also refer to wider implications for road charging policy, including how any expanded scheme could affect who pays and under what rules. The articles do not provide detailed figures or specific technical thresholds in the excerpts provided, but they consistently state that the recommendation is to broaden the road-user charge to reduce the risk of the policy being invalidated.
