HB 409 Montana House · 2025 Regular Session

Revise injunction laws

HB 409 amends Montana law to prohibit courts from using "sliding scale" tests like the "serious questions test" when reviewing requests for preliminary injunctions or temporary restraining orders. The bill requires courts to apply only the standard set by U.S. Supreme Court precedent, which focuses on four factors: likelihood of success on the merits, irreparable harm, balance of equities, and public interest. This directly affects Montana courts and anyone seeking emergency court orders to halt actions (e.g., property disputes or restraining orders). The law takes immediate effect upon signing, ensuring all injunction applications follow federal judicial standards instead of prior Montana court interpretations.

MINOR
This bill amends Montana's law on preliminary injunctions to strictly prohibit courts from using 'sliding scale' or 'serious questions' tests, requiring judges to evaluate the four legal criteria independently instead. The change ensures Montana courts follow United States Supreme Court precedent rather than the 9th Circuit Court of Appeals' approach, which previously allowed for a more flexible, multi-factor analysis. This update clarifies legislative intent to prevent courts from weighing factors against each other, thereby standardizing how temporary legal relief is granted.
Scope change
The bill's scope remains focused on Montana courts' procedures for granting preliminary injunctions and temporary restraining orders, but it significantly alters the analytical framework judges must use when deciding these cases.
REQUIREMENT

Prohibits courts from using sliding scale tests, serious questions tests, flexible interplay, or other federal circuit modifications when analyzing injunction applications.

Mandates that courts examine the four statutory criteria for injunctions independently rather than weighing them against one another.
