MT HB409

Prohibits Montana courts from using the "serious questions test," sliding scale tests, flexible interplay, or other federal circuit court modifications when evaluating preliminary injunctions and temporary restraining orders

Requires courts to examine each of the four preliminary injunction criteria independently: likelihood of success on the merits, irreparable harm, balance of equities, and public interest

Mandates that Montana courts follow U.S. Supreme Court precedent rather than 9th Circuit Court of Appeals decisions when applying the preliminary injunction standard

Responds to the Montana Supreme Court's decision in Stensvad v. Newmay Ayers Ranch, Inc., which adopted the serious questions test contrary to legislative intent expressed in 2023 amendments

Effective immediately upon passage and approval
