Montana Supreme Court

State v. L. Johnson

June 30, 20262026 MT 138N

Summary

The Court affirmed Johnson’s misdemeanor conviction after concluding that officers had particularized suspicion to initiate the traffic stop and expand it into a DUI investigation. The Court also upheld admission of the Intoxilyzer results because Johnson failed to develop her evidentiary challenges, and declined to address her independent-blood-test claim because it was raised for the first time on appeal and therefore waived.
