NATALIE R. V. STATE OF UTAH

On March 20, 2025, the Utah Supreme Court issued a partial win for the youth, allowing them to continue their legal efforts to challenge specific state actions promoting fossil fuel development. The Justices offered the youth plaintiffs a path forward to amend their complaint, address the Court’s concerns, and continue fighting for their rights to life, health, and safety amid the climate crisis. 

Acknowledging the vast amounts of fossil fuels extracted in Utah, the Supreme Court ruled that in order for courts to be able to provide plaintiffs with a meaningful remedy, they needed more specificity about the government conduct plaintiffs were challenging. 

The youth plaintiffs and their attorneys are now pursuing every available avenue to continue advocating for the protection of Utah’s youth from climate-related harm.

Current Status

On March 15, 2022, seven youth from across the state of Utah filed their constitutional climate lawsuit against the state of Utah, Natalie R. v. State of Utah. The case argues that, through its statutory policy to maximize, promote, and systematically authorize the development of fossil fuels in Utah, the State is actively causing and contributing to Utah’s hazardous air quality and dangerous climate crisis impacts, harming the young plaintiffs and violating their state constitutional rights to life, health, and safety.

The youth plaintiffs claim that their state government has long known of the dangers of fossil fuels yet has continued to take affirmative actions that worsen air pollution and the climate crisis in the Beehive State, resulting in increasingly hazardous air quality and climate impacts that directly harm Utah’s children. 

The youth plaintiffs are represented by Andrew Welle with Our Children’s Trust and Andrew Deiss, John Robinson, and Corey Riley with Deiss Law PC.

September 4, 2024: Parties Presented Oral Arguments Before the Utah Supreme Court   

Before a panel of Utah Supreme Court judges, attorney for the youth plaintiffs argued why the case should proceed to trial, asserting that the statutes challenged in this case unconstitutionally mandate the State to promote, foster, and authorize fossil fuel development on a system-wide basis, despite knowledge of its direct impacts to young peoples’ health and safety. This promotion, they argue, is directly responsible for Utah’s deteriorating air quality and increasingly dangerous climate conditions, which the young Utahns are unable to escape. The plaintiffs bring this facial challenge to these policies, claiming they violate their fundamental rights under Utah’s State Constitution.

The Utah Supreme Court today issued a ruling in the youth-led constitutional climate lawsuit Natalie R. v. State of Utah, which allows the plaintiffs to continue their legal efforts to challenge specific state actions promoting fossil fuel development. The ruling clears the way for the youth to amend their complaint, focusing on how state actions that endanger plaintiffs’ health and safety and contribute to hazardous air quality and climate change violate their constitutional rights to life and liberty. This decision also confirms that Utah’s energy laws do not mandate automatic approval of fossil fuel projects, granting the state full discretion to reject fossil fuel development because of climate change, including coal mining.
