Montana Judge’s Verdict Sets Precedent for Climate Lawsuits

In a groundbreaking decision, Montana District Judge Kathy Seeley, who presided over the United States’ inaugural constitutional climate trial earlier this year, has ruled in favor of a group of young plaintiffs. These plaintiffs had accused Montana state officials of violating their fundamental right to a healthy environment by imposing restrictions on the consideration of climate impacts during the approval process for energy projects.

The plaintiffs drew strength from a provision in Montana’s constitution that enshrines the right to "a clean and healthful environment." The focal point of their concerns was a clause within the Montana Environmental Policy Act (MEPA), which had hitherto prevented the state from factoring in the repercussions of its energy economy on climate change. Earlier this year, state legislators amended this clause to explicitly bar the consideration of greenhouse gas emissions in environmental assessments for new energy initiatives.

Judge Seeley deemed this particular provision unconstitutional in her decisive ruling on Monday. Additionally, she issued an injunction against another 2023 state policy, which had imposed more stringent restrictions on groups’ ability to legally challenge government agencies over permitting decisions under the Montana Environmental Policy Act.

This judgment is anticipated to have ripple effects, potentially inspiring similar legal actions globally. Julia Olson, chief legal counsel of Our Children’s Trust, the organization representing the plaintiffs, conveyed her belief that this case could serve as a pivotal "turning point." While comparable cases have been initiated by young environmentalists at both state and federal levels, none went to trial. Climate activists are optimistic that this landmark ruling will invigorate similar lawsuits aimed at addressing the urgent climate crisis.
