Juliana v. United States 

Date: 17 January 2020 

Court: U.S. Court of Appeals for the Ninth Circuit 

Citation(s): Juliana v. United States, 947 F.3d 1159 (9th Cir. 2020)

Short summary  

A group of young people sued the United States government for failing to prevent climate change, seeking an order requiring the government to develop a plan to phase out domestic fossil fuel emissions. The plaintiffs claimed violations of their substantive due process, equal protection, the Ninth Amendment, and the public trust doctrine. The court found that the plaintiffs established injury-in-fact and causation for Article III standing but that their claim failed for lack of redressability.

Weight of decision  

This decision comes from the Ninth Circuit of the United States Court of Appeals and is therefore binding on all courts in the Circuit and persuasive in other federal courts.   

Key facts 

The plaintiffs were twenty-one young citizens, an environmental organization, and a “representative of future generations.” [1165] They sued the President (later dismissed from the action), the United States, and federal agencies. The complaint accused the government of continuing to “permit, authorize, and subsidize” [1165] fossil fuel use, despite awareness of its risks, leading to various climate-change-related injuries. The plaintiffs’ claims varied from psychological harm and impairment of recreational interests to exacerbated medical conditions and property damage. 

The complaint asserted violations of the plaintiffs’ constitutional rights: 

“(1) the plaintiffs’ substantive rights under the Due Process Clause of the Fifth Amendment; (2) the plaintiffs’ rights under the Fifth Amendment to equal protection of the law; (3) the plaintiffs’ rights under the Ninth Amendment; and (4) the public trust doctrine.” [1165] 

The plaintiffs sought declaratory relief and an injunction ordering the government to implement a plan to “phase out fossil fuel emissions and draw down excess atmospheric [carbon dioxide].” [1165] 

The court noted that the District Court record and this appeal recognized climate change is occurring at a rapid pace. The court stated that rising carbon emissions would wreak havoc on the Earth’s climate if left unchecked, and that the federal government long understood these risks and affirmatively contributed to their worsening. 

The government largely did not contest the factual basis for the plaintiffs’ claims, only that they lacked standing to pursue them. 

Previous instances  

The District Court denied the government’s motion to dismiss. That court stated that the plaintiffs had standing to pursue their claims that the government violated their constitutional rights, including a Fifth Amendment right to a “climate system capable of sustaining human life.” [1165] The District Court also found a separate viable “danger-creation due process claim” [1165] based on the government’s lack of regulation on third-party emissions and a public trust doctrine claim. 

At summary judgment, the District Court dismissed the President as a defendant and dismissed the plaintiffs’ Equal Protection claim in part. That court also dismissed the plaintiffs’ Ninth Amendment claims. The government then sought this interlocutory appeal to resolve the standing issue and other grounds for dismissal.

In re Katrina Canal Breaches Litigation 

Date: 18 November 2009

Court: United States District Court, Eastern District of Louisiana

Citation: 647 F. Supp. 2d 644

Short summary  

Hundreds of thousands of homes were lost in Hurricane Katrina and most homeowners’ insurance policies excluded them from compensation. This led many victims of Katrina to sue the United States government under the Federal Tort Claims Act (FTCA), alleging the U.S. Army Corps of Engineers (Corps) failed to properly maintain the Mississippi River Gulf Outlet, leading to the breach of one of New Orleans’ levees. The District Court held the U.S. was not immune from such a suit and held the Corps liable to some of the plaintiffs. This judgment was later reversed by the Fifth Circuit Court of Appeal, on the grounds that the U.S. has sovereign immunity under the FTCA from such claims.

Weight of decision  

The ruling by the Eastern District of Louisiana District Court, insofar as its logic was affirmed by the Court of Appeals, holds precedential authority in the Fifth District (Texas, Louisiana, Mississippi) and persuasive authority in other U.S. Circuits (see, e.g., favourable analysis in the Northern and Central Districts of Illinois). However, this ruling has subsequently been read narrowly by the same Eastern District court (holding there must be “ample record evidence” the government neglected its duty to maintain waterways implicated in flooding).  

Key facts 

Under the Federal Tort Claims Act (FTCA; 28 USC §171), the U.S. government is immune from liability if its (in)action can be classified as a discretionary function (i.e., a policy decision left to an agency via legislation) rather than a specifically delegated ministerial duty not executed with due care.  

Under the Flood Control Act (FCA; 33 USC §702c), the U.S. government is immune from liability for damage stemming from its flood control efforts.  

The U.S. Army Corps of Engineers’ (Corps) were charged with construction, maintenance, and operation of the Mississippi River Gulf Outlet (MRGO), a navigational channel. This mandate was separate from the Corps’ efforts directed at flood control and levee construction and maintenance in southern Louisiana.  

Over decades, the Corps failed to prevent the MRGO from expanding well beyond its intended width, destroying wetlands which are protective against storm surges. This in contravention of the National Environmental Policy Act and despite repeated internal and external reports warning of the danger of not shoring up the MRGO’s banks. This failure was a substantial cause of the breach of a levee, leading to catastrophic flooding of St. Bernard parish in the New Orleans metropolitan area.  

Previous instances  

This case relies on Central Green v. United States (U.S. Supreme Court, 2001), wherein Justice Stevens held that the U.S. was not entitled to immunity under the FCA from damage caused by any and all flood waters. Instead, the government must show that flooding is connected with projects serving a primarily flood control purpose, in order for mismanagement of such projects to grant immunity.

Hagi-Mohamed v Minister for Immigration & Multicultural Affairs [2001] FCA 1156

Date of judgement: 23 August 2001

 Court: Federal Court of Australia

Citation(s): [2001] FCA 1156

Short summary 

The Federal Court of Australia confirmed that internal relocation must be considered separately from the question of whether a well-founded fear of persecution exists in evaluating claims for protection under the 1951 Refugee Convention.

Summary by: Joseph Lavelle Wilson            


Weight of decision

This decision of the Federal Court bears moderate weight in the Commonwealth of Australia. 

Key facts

Ahmed Dahir Hagi-Mohamed, a citizen of Somalia, arrived in Australia on 15 September 1995. He filed an application for a protection visa under s. 36 of the Australian Migration Act 1958 (Cth) in November 1995, claiming that the Australian government had an obligation to protect him under the Convention Relating to the Status of Refugees 1951 (the Convention). The basis of his application was that he had a well-founded fear of persecution in his home country of Somalia, due to his membership of several social groups. 

Hagi-Mohamed claimed that he was a member of the particular social group (that of homosexual men), as well as a member of two clans – the Geledi clan and the Hawadle clan.

Previous instances

The Minister for Immigration & Multicultural Affairs and the Refugee Review Tribunal (RRT) rejected the application for protection. The RRT accepted that each group identified by Hagi-Mohamed was in fact a particular social group, and that he belonged to each one. The RRT found that the motivating reason for the persecution of Geledi clan members by Somalian militias was to take resources from the Geledi clan, specifically arable land and crops, rather than for the reason that they were members of the Geledi clan. The RRT also found that Hagi-Mohamed’s association with his mother’s clan, the Hawadle, did not put him at risk of persecution because there was evidence that other parts of Somalia were controlled by the Hawadle and he could be safe there. With respect to Hagi-Mohamed’s claim based on his homosexuality, the RRT found that although he did belong to the cognisable social group, that group did not face danger rising to the level of persecution under the Convention.

Hagi-Mohamed appealed to the Federal Court of Australia. Justice Stone issued a decision in favour of the government, which was subsequently appealed by Hagi-Mohamed and heard by Justices Wilcox, Weinberg, and Hely in the Federal Court of Australia.
