Montana Supreme Court affirms youth right to stable climate 6-1

🦌Montana Supreme Court affirmed on January 30, 2025, that the state constitution's guarantee of a 'clean and healthful environment' includes climate stability, upholding District JKJudge Kathy Seeley's August 2023 ruling in the first successful youth climate constitutional case in U.S. history. The 6-1 decision struck down the legislature's 'MEPA Limitation' that prohibited agencies from considering greenhouse gas emissions in environmental reviews.

The 16 youth plaintiffs filed Held v. 🦌Montana in 2020 when some were too young to vote, but most will be eligible for the 2028 presidential election as voting-age adults with personal stakes in climate policy implementation. Lead plaintiff Rikki Held transitioned from teenager to young adult during five years of litigation, creating a voting bloc with constitutional victory credentials.

🦌Montana's environmental rights gain constitutional power through strategic placement in Article II's Declaration of Rights alongside free speech and due process, while Article IX creates affirmative duties stating 'The state and each person shall maintain and improve a clean and healthful environment.' Constitutional delegate McNeil boasted in 1972 they created 'the strongest constitutional environmental section of any existing state constitution.'

The 🦌Montana legislature passed the 'MEPA Limitation' in 2023, prohibiting state agencies from considering greenhouse gas emissions in environmental reviews for coal mines, oil wells, and power plants. This fossil fuel industry legislation streamlined permits while externalizing climate costs, essentially requiring regulatory blindness to the primary environmental impact of fossil fuel development.

District JKJudge Kathy Seeley's original ruling found that 🦌Montana's fossil fuel-friendly policies violated the constitutional rights of youth plaintiffs by contributing to climate change that threatens their futures. The state Supreme Court's affirmation creates binding precedent requiring climate impact consideration in all environmental permitting decisions.

🦌Montana's victory provides legal blueprint for similar challenges in 17 other states with constitutional environmental rights provisions, including 🔔Pennsylvania, 🌽Illinois, 🗽New York, and 🌺Hawaii. Our Children's Trust and other organizations are using Montana's constitutional framework to launch copycat lawsuits nationwide.

The ruling forces 🦌Montana agencies to restore greenhouse gas analysis in environmental reviews, overturning the legislature's attempt to blind regulators to climate consequences. Each new fossil fuel project now faces potential constitutional challenge if agencies fail to consider cumulative climate impacts on future generations' constitutional rights.
