SB 239 Montana Senate · 2025 Regular Session

Requiring judges to invite amicus briefing and allow intervention in certain civil cases

SB 239 would have required district courts to invite local governing bodies to submit "friend of the court" briefs in civil cases that challenge subdivision applications or other land use decisions, specifically when the court is interpreting relevant statutes. This provision aimed to allow local governments, or groups representing them, to offer their perspective on how the law should be interpreted. Additionally, the bill would have permitted these governing bodies, after submitting a brief, to formally join the case (intervene) if an order interpreting the statute was issued, and to request a pause (stay) of that order during an appeal. The bill primarily affects courts, local governing bodies, and parties involved in legal disputes over land use and subdivision regulations.
