Summary:
On 12 August 2015, the Juliana v. the United States case was filed in the U.S. District Court for the District of Oregon. The 21 youth plaintiffs in this case, who were represented by the NGO “Our Children’s Trust”, asserted that the government had violated the youngest generation’s constitutional rights to life, liberty and property through its climate change-causing actions. Among other things, they argued that they had suffered psychological harms, damage to property, impairment to their recreational interests, and that their medical conditions had been exacerbated by the effects of climate change. They sought declaratory relief and an injunction ordering the government to implement a plan to phase out fossil fuels. Moreover, they stated that the government had failed to protect essential public trust resources by encouraging and permitting the combustion of fossil fuels. After extensive proceedings, the Ninth Circuit Court of Appeals ordered the dismissal of the case in 2024, and the US Supreme Court refused to grant certoriari in March 2025, effectively ending the case.
The Ninth Circuit’s 2020 decision:
The Government filed a large number of motions to stay or deny these procedings. However, U.S. District Court of Oregon Judge Ann Aiken declined to dismiss the lawsuit. She ruled that access to a clean environment constitutes a fundamental right. Judge Aiken’s judgment was reversed by a Ninth Circuit Panel on 17 January 2020 due to the plaintiffs’ lack of standing to sue. The Ninth Circuit Court of Appeals recognized the gravity of the evidence on the plaintiffs’s injuries from climate change. The panel of judges also recognized the existence of harms to the applicants, and the plausibility of arguing that these harms had been caused by climate change. Nevertheless, the Court held that the plaintiffs’ requested remedies should be addressed by the executive and legislative branches and not by the courts. As a result, they “[r]eluctantly” held that “such relief is beyond [their] constitutional power.”
One of the three judges affirmed the plaintiff’s constitutional climate rights in a dissent, arguing that the case sought to enforce the US Constitution’s most basic principle: “that the Constitution does not condone the Nation’s willful destruction.” Accordingly, she held that the plaintiffs had standing to challenge the government’s conduct, and had presented sufficient evidence to press their constitutional rights claims at trial.
Further proceedings:
On 9 March 2021, the plaintiffs filed a motion to amend their complaint and adjust the remedy sought in the case. After settlement talks ended without resolution in November 2021, and Judge Aiken granted the plaintiff’s motion for leave to file a second amended complaint in June 2023. The plaintiffs argued that the government’s failure to address climate change violated their rights under the Fifth and Ninth Amendments and the Public Trust Doctrine. The amended complaint requested the court to issue an injunction restraining the defendants from carrying out policies, practices that render the national energy system unconstitutional in a manner that harms the plaintiffs.
In December 2023, the court partially denied the defendants’ motion to dismiss the second amended complaint, allowing claims related to the right to a climate system capable of sustaining life under the Due Process Clause and the Public Trust Doctrine to proceed. However, in February 2024, the government filed an emergency petition for a writ of mandamus, which was granted by a three-judge panel of the Ninth Circuit Court of Appeals in May 2024. This order required the district court to dismiss the case and preclude any further amendments. Subsequently, the district court dismissed the case.
These were complex proceedings, with several intermediate filings and actions. However, on 24 March 2025, the US Supreme Court denied the plaintiffs’ petition for a writ of certoriari. The plaintiffs had sought review of the order of the Ninth Circuit of May 2024, which granted the government’s request for a writ of mandamus and ordered the district court to dismiss the case. At the time of writing, this seems to have effectively ended the case.
Proceedings before the Inter-American Commission on Human Rights:
On 23 September 2025, the NGO Our Children’s Trust announced that it had filed a petition before the Inter-American Commission on Human Rights alleging climate-related violations of human rights by the government of the United States of America on behalf of some of the plaintiffs in the present case.
