The Federal Court of Australia has made a significant legal precedent by admitting a UN special rapporteur on human rights and the environment as an intervenor in a case challenging the extension of a liquefied natural gas (LNG) operation site. This marks the first occasion the court has allowed a UN environmental expert to provide input on international environmental law, a development that could influence future legal proceedings in Australia involving environmental issues.
Astrid Puentes Riaño, the Special Rapporteur on the human right to a clean, healthy, and sustainable environment, will participate as amicus curiae in the judicial review. Her role is to provide expert advice on international legal standards for assessing the environmental impacts of projects before they are authorized. The context includes a unanimous advisory opinion by the International Court of Justice, which pointed out states’ obligations to prevent environmental harm, a principle endorsed by Australia in a UN General Assembly resolution earlier this year.
The case, initiated by the Australian Conservation Foundation, alleges that Environmental Minister Murray Watt unlawfully extended the operating life of the North West Shelf (NWS) Project. The foundation argues that the minister did not appropriately assess the project’s climate impact on the Dampier Archipelago and relied on economic benefits from an unrelated project. This lawsuit runs parallel to another from the Friends of Australian Rock Art, which contends that the approval process neglected the potential damage to the Murujuga Cultural Landscape.
Minister Watt, when renewing the project’s extension for 45 years from 2025, had imposed stringent conditions, including a 60% reduction in gas emissions by 2030 to mitigate climate impacts on local rock art. Despite these precautions, the NWS project, one of Australia’s largest LNG operations, poses significant environmental concerns, as its lifetime emissions could be 13 times the nation’s total annual emissions, according to a report by the Australian Conservation Foundation.
This decision by the Federal Court underscores the growing influence of international environmental law in domestic legal systems. As global scrutiny over climate change intensifies, the involvement of UN experts in national judicial processes may become more common, a trend reflective of the complex intersection of environmental and human rights law in contemporary legal practice.
