In an attempt to have his driver’s license reinstated after refusing a breath test, Brown argued that only an experienced officer could make the proper inferences to justify compelling a breath sample. SCOMONT noted that in a driver’s license reinstatement proceeding, “the court is limited to deciding whether the peace officer had reasonable grounds to believe that the person had been driving or was in actual physical control of a vehicle upon ways of this state open to the public while under the influence of alcohol […]” Brown, ¶ 11 (internal citations omitted). The reasonable grounds requirement is equivalent to particularized suspicion in an investigative stop. “[T]he test for particularized suspicion simply requires that the information available to the investigating officer – whether a rookie or a veteran – be sufficient to allow a hypothetical ‘experienced’ officer to have either particularized suspicion for a stop, or probable cause for an arrest.” Brown, ¶ 19.
The Court acknowledged that several cases implied an “experienced officer” requirement (State v. Gopher, 193 Mont. 189 (1981), State v. Schatz, 194 Mont. 59 (1981), and State v. Morsette, 201 Mont. 233 (1982)) but found that these evolved from various early misinterpretations of the U.S. Supreme Court’s decision in United States v. Cortez, 449 U.S. 411 (1981). Attempting the remedy the confusion, SCOMONT stated:
Therefore, we hold that, henceforth, for a peace officer to have particularized suspicion or reasonable grounds for an investigatory stop, the peace officer must be possessed of: (1) objective data and articulable facts from which he or she can make certain reasonable inferences; and (2) a resulting suspicion that the person to be stopped has committed, is committing, or is about to commit an offense. While a peace officer’s experience and training may be a factor in determining what sort of reasonable inferences he or she is entitled to make from his or her objective observations, experience and training will not necessarily be the defining element of the test.
Brown, ¶ 20. Here, where the officer smelled alcohol in Brown’s vehicle, it was 2:51 a.m., Brown’s vehicle had been moving slowly down the street before abruptly pulling over, stopping and turning off the headlights, Brown’s speech was slow and slurred, Brown made a slow and staggered exit from the vehicle, Brown admitted that he had been drinking earlier in the night, and there was a plastic Budweiser container in the pickup’s cupholder, there was sufficient evidence for the officer to believe that Brown was driving under the influence of alcohol. The District Court’s conclusion that the deputy had reasonable grounds to believe that Brown was driving under the influence of alcohol was affirmed.
