Michigan v. Hartwick Case Brief: Probable Cause in OWI Arrests Without Preliminary Breath Test

Case Brief: Michigan v. Hartwick

Court: Michigan Supreme Court
Citation: Michigan v. Hartwick, 870 N.W.2d 37 (Mich. 2015)
Decided: March 24, 2015

Facts:

In Michigan v. Hartwick, the defendant, Hartwick, was charged with operating a motor vehicle while intoxicated (OWI). During the traffic stop, the officer noted that Hartwick exhibited signs of intoxication, including slurred speech and an odor of alcohol. Hartwick refused to take a preliminary breath test (PBT), and subsequent tests confirmed his high blood alcohol content (BAC). Hartwick argued that the police did not have probable cause for his arrest because they did not perform the PBT as required by Michigan law.

Issue:

The key issue was whether the officer had probable cause to arrest Hartwick for OWI without administering a PBT, as mandated by Michigan law.

Holding:

The Michigan Supreme Court held that the officer had probable cause to arrest Hartwick for OWI based on the totality of the circumstances, including the officer's observations of Hartwick's behavior and the physical evidence of intoxication.

Legal Reasoning:

The court reasoned that while Michigan law requires a PBT in certain situations, an officer's failure to administer one does not necessarily negate probable cause for arrest. The decision emphasized the following points:

• Totality of Circumstances: The court reiterated that probable cause is assessed based on the totality of circumstances, which can include an officer's observations, the driver's behavior, and any physical evidence.
• Indicators of Intoxication: Hartwick’s slurred speech, the strong odor of alcohol, and other observable signs of impairment were sufficient for the officer to conclude that Hartwick was driving under the influence.
• Public Safety: The court emphasized the importance of public safety and the officer's duty to prevent intoxicated individuals from operating vehicles, thereby justifying the arrest despite the procedural lapse regarding the PBT.

The court concluded that the officer had acted within the bounds of the law and that Hartwick's arrest was lawful based on the observed evidence of intoxication.

Conclusion:

The ruling in Michigan v. Hartwick clarifies the standards for establishing probable cause in OWI cases, reaffirming that officers can make lawful arrests based on observed behavior and circumstances even if all procedural steps, such as administering a PBT, are not followed.
