Lawsuits Challenge Montana Public Service Commission's Climate Oversight
What happened
Seventeen organizations, including Earthjustice and Western Environmental Law Center, filed lawsuits against the Public Service Commission in Missoula County District Court on October 17, 2026. The groups argue that state regulators must be required to consider climate change when making decisions about Montana's energy future. This legal challenge follows the Public Service Commission's rejection of a request in September 2025 to formally recognize this responsibility.

Why it matters
The lawsuit challenges the Public Service Commission's regulatory authority over energy policy in Montana. Groups argue that the commission's decisions regarding gas and electric utilities have long-lasting consequences for what Montana residents pay. The Public Service Commission has argued that it is an administrative agency and does not have the authority to interpret the state constitution.
The Public Service Commission is currently regulating various utilities operating within the state of Montana.
