A United Nations special rapporteur, Astrid Puentes Riaño, has been granted permission to make submissions in Australian Federal Court cases challenging the extension of the Woodside Energy North West Shelf gas project. This marks an unprecedented intervention in Australia, with the court accepting her input as an amicus curiae, or "friend of the court." The rapporteur's filings are expected to address Australia's international legal obligations and the context of international law in interpreting national environmental regulations.
The core of the legal challenges, brought by the Australian Conservation Foundation (ACF) and Friends of Australian Rock Art (FARA), centres on claims that the environmental assessment for the project's 40-year license extension failed to adequately consider its climate impacts. Justice Catherine Button accepted Ms. Puentes Riaño's submissions last week, a move that adds an international human rights dimension to the domestic legal battle.

The UN rapporteur's intervention signifies a potential broadening of the legal landscape, introducing international human rights frameworks into a domestic environmental law dispute. This development follows an application made by the rapporteur to intervene in the proceedings, which were initially heard in November 2025 and are set to resume in July 2026. The court's decision to allow these submissions underscores the growing global focus on the intersection of human rights and environmental policy.
Legal Pathways and International Scrutiny
The Federal Court cases challenging the extension of the North West Shelf gas project's license are scheduled to resume in Melbourne in July 2026. The inclusion of UN rapporteur submissions means that Australia's compliance with its international legal commitments related to a clean, healthy, and sustainable environment will likely be a focal point. This legal manoeuvre highlights a push by environmental groups and human rights advocates to link national environmental decisions to broader international human rights standards.

The Australian Human Rights Commission has previously recommended that the Australian government implement policies to phase out fossil fuels, ban new fossil fuel projects, and regulate their trade. This background provides context for the rapporteur's stated interest in addressing the international law surrounding these issues.
Background and Precedents
This intervention by a UN special rapporteur in an Australian legal case is a first. Ms. Puentes Riaño, the UN Special Rapporteur on the human right to a clean, healthy and sustainable environment, is an independent expert tasked with reporting on human rights issues. Her involvement as amicus curiae allows her to provide expertise without being a direct party to the litigation.
Woodside Energy reportedly opposed the application on procedural grounds, arguing it was made independently of the UN. Similar legal challenges in Australia, such as the one that delayed the Santos Barossa gas field development, have previously been dismissed on appeal, suggesting a complex legal history for such cases. The environmental assessment in question was approved by Environment Minister Murray Watt in September of the previous year. The full court hearings are expected to commence on July 21, 2026, and run for approximately one week.
