Lawsuit Seeking to Hold Federal Government Accountable for Climate Change Likely to Advance to Trial

A climate change lawsuit involving constitutional “issues of first impression”1 recently achieved a small victory as it pursues a court order directing the U.S. federal government to take actions to reduce greenhouse gas (“GHG”) emissions.  On March 7, 2018, the U.S. Court of Appeals for the 9th Circuit denied the Trump Administration’s (the “Government”) Petition for a Writ of Mandamus2 seeking to dismiss Juliana v. U.S.,3 a 2015 lawsuit filed by Our Children’s Trust  in the U.S. District Court for the District of Oregon on behalf of twenty-one children and young adults (“Plaintiffs”). 

Plaintiffs have continued to hope that they may have an opportunity to advance the merits of their case through discovery, potential summary judgment, and ultimately, at trial—i.e., that the federal government’s historical promotion of fossil fuels and regulatory inaction on climate change violates Plaintiffs’ and future generations’ fundamental right to a stable climate system, whose protection is necessary to secure their fundamental rights to life, liberty, and property.Though it “well may be” that Plaintiffs’ claims “are too broad to be legally sustainable,”5 Juliana’s recent success could motivate additional lawsuits as U.S. states, cities, and civil society seek to force federal action and reparations for climate change damage.


Juliana parallels similar efforts by Our Children’s Trust to shape climate policy at the state-level via the “public trust doctrine,”6 which provides that state and federal governments, as trustees of “vital natural resources” such as “air (atmosphere), water, seas, the shores of the sea, and wildlife,” have a duty to preserve and protect such resources for its beneficiaries.7  In Juliana, Plaintiffs allege that the federal government violated the public trust and Plaintiffs’ and future generations’ fundamental rights to life, liberty, and property by “deliberately allow[ing] . . . CO2 concentrations to escalate to levels unprecedented in human history,” the severity of which necessitates “immediate action”: a court-mandate directing the government to “phase-out fossil emissions and draw down excess atmospheric CO2.”8

The Government’s9 first attempt to dismiss the case was denied in 2016 by the district court, which held that the federal government is not immune to the public trust doctrine.  Distinguishing Juliana from previous cases—which implied that the doctrine was a matter of state law—the judge concluded that “[t]he federal government, like the states, holds public assets . . . in trust for the people.10 The judge therefore found that Plaintiffs adequately alleged harm to a federal public trust asset, the territorial sea (i.e., the federal government’s alleged actions resulted in ocean acidification and rising ocean temperatures).11  As the judge concluded, Plaintiffs’ “right to a climate system capable of sustaining human life is fundamental to a free and ordered society” that must be protected by the Government,12 thereby allowing Juliana to proceed towards discovery.

The district court also denied the Government’s motion to certify the court’s order for interlocutory appeal,13 prompting the Government’s mandamus Petition in a “‘drastic and extraordinary’” attempt to dismiss the case.14 The Government’s Petition sought relief on three grounds: (1) continuance of the case will lead to “intrusive and inappropriate discovery” that threatens the separation of powers; (2) the district court’s order was based on clear error; and (3) Juliana raises important issues of first impression that may evade appellate review.

9th Circuit Decision

The 9th Circuit denied each of the Government’s claims, finding that they are “better addressed through the ordinary course of litigation.”15  First, the court explained that the Government’s fear of “burdensome discovery obligations” is premature since the district court had not issued a single discovery order.16  Second, because the Government is not exempt “from the normal rules of appellate procedure,” the court found that a threat to the separation of powers does not exist.17  Finally, while “there is little doubt” that Juliana raises issues of first impression, the court declined to “opine” on the merits or review “preliminary legal decisions made by the district court,” concluding that the Government has “ample opportunity to raise legal challenges . . . on a more fully developed record.”18


The 9th Circuit’s decision affords Plaintiffs the right to conduct discovery and proceed to a trial originally scheduled for early February 2018.  Trial is not guaranteed, of course, as a 9th Circuit panel review or Supreme Court intervention are remaining options for the Government as is undoubtedly an additional motion seeking to dismiss the matter following discovery.19

Should the case proceed, a March 21, 2018 climate change tutorial held by the 9th Circuit in People of the State of California v. BP P.L.C. likely foreshadows what is in store for the Government in Juliana: a battle between Plaintiffs and the Government over climate science.20 While Plaintiffs’ claims concern the federal government’s “aggregate actions” dating back to 1965,21 the Trump Administration’s inheritance of Juliana from the Obama Administration puts it in the uncomfortable position of defending its climate change agenda in the face of an overwhelming body of scientific evidence and a heightened sense of urgency for climate action by U.S. states, cities, and the international community.

Juliana ultimately will need to overcome a number of legal and technical issues likely to be scrutinized on the merits, including the causal nexus between Plaintiffs’ alleged harms and the Government’s actions, or the potential displacement of Plaintiffs’ claims by the Government’s vested authority to regulate emissions under the Clean Air Act.22 No matter the outcome, the 9th Circuit’s decision suggests that courts previously “cautious and overly deferential in the arena of environmental law”23 may be willing to give Juliana and future plaintiffs a fair shot at success.

11 Juliana, 217 F.
