January 16, 2026: Youth Plaintiffs Refile in District Court

The youth plaintiffs filed their enforcement case at the First Judicial District Court, Broadwater County, following direction from the Montana Supreme Court. 

While the core arguments remain the same; asking the court to declare the 2025 MEPA and Clean Air Act amendments unconstitutional, restore the state’s authority to regulate greenhouse gas pollution, and uphold youth’s constitutional right to a clean and healthful environment and a stable climate system, the case now includes three additional youth plaintiffs from across Montana, each experiencing real and ongoing harm caused by the state’s unconstitutional laws.
