The 70-page decision, authored by Chief Justice Mike McGrath, comes 16 months after Lewis and Clark District Court Judge Kathy Seeley ruled in the landmark Held v. Montana lawsuit, explicitly stating that the state’s greenhouse gas emissions are “proven to be a substantial factor in causing climate impacts to Montana’s environment, and harm and injury to the youth plaintiffs.” Seeley’s decision also rolled back two laws enacted by the 2023 legislature that changed the Montana Environmental Policy Act.

The state immediately appealed the decision to the Montana Supreme Court, which heard oral arguments in the appeal in July.

Damn, congrats to the plaintiffs!
