On September 16-17, 2025, history will be made in a federal courtroom in Missoula, Montana. For the first time ever, a federal judge will hear live testimony in a constitutional climate case led entirely by young people. The case, Lighthiser v. Trump, isn’t just a legal milestone—it’s a moment of truth for the next generation and the future of our planet.
The stakes couldn’t be higher. The 22 youth plaintiffs are challenging three executive orders issued under the current administration that:
- Unleash fossil fuel extraction and use at an unprecedented scale
- Block the deployment of clean, renewable energy like wind and solar
- Suppress climate science, replacing evidence-based policy with misinformation
These executive orders don’t just threaten abstract concepts—they directly endanger the health, safety, and constitutional rights of young people. Every ton of fossil fuel pollution released under these policies causes measurable harm to the plaintiffs. Meanwhile, wind and solar energy are already among the cheapest and most reliable sources of power, ready for immediate deployment, yet they are being blocked.
Why this hearing matters
The Missoula hearing will focus on two critical motions: the plaintiffs’ motion for a preliminary injunction to halt the implementation of these harmful executive orders, and the government’s motions to dismiss the case entirely. The youth plaintiffs, represented at no cost to them or their guardians, will present unrefuted, compelling evidence from expert witnesses including:
- A Nobel Prize-winning climate scientist
- Stanford energy and economics experts
- Pediatricians highlighting the health impacts on children
- Leaders in renewable energy development
- Former White House climate and energy policy advisors
Notably, the federal and state governments have chosen not to present a single witness, leaving the plaintiffs’ testimony unchallenged. This highlights both the seriousness of the case and the courage of the young people stepping forward to defend their constitutional rights.
What’s at stake if the injunction is granted
If the court rules in favor of the preliminary injunction, the federal government would be legally barred from implementing these executive orders. This would mean:
- A halt to unnecessary fossil fuel expansion
- Removal of barriers to wind and solar development
- Protection of critical climate science that informs public policy
The injunction would protect the youth plaintiffs while the case proceeds toward a full trial on the merits. It represents a powerful legal tool to safeguard the health and future of young Americans, while signaling to the world that constitutional rights extend to protection against climate harm.
