State v. Ellis-Peterson

Summary

The Montana Supreme Court affirmed the denial of Dawnalee Ellis-Peterson’s motion to suppress evidence following her arrest for driving under the influence. The court held that the arresting officer had probable cause based on his observations of her intoxication, her admission that she was drunk, her driving, and related circumstances, and that field sobriety testing was not required. The court issued the decision as a noncitable memorandum opinion under its Internal Operating Rules.

Holdings

1. Officer Beck had probable cause to arrest Ellis-Peterson for driving under the influence without a warrant because the facts personally observed by him, considered in light of his law-enforcement training, were sufficient to warrant a reasonable belief that she was driving while intoxicated.
2. Field sobriety testing is not a prerequisite to a finding of probable cause to arrest for DUI, and the absence of such testing does not by itself invalidate the probable-cause determination.
3. The public-safety threat posed by an intoxicated driver with a suspended license constituted an existing circumstance justifying immediate warrantless arrest.

Questions Presented

1. Whether Officer Beck had probable cause to arrest Ellis-Peterson for driving under the influence without a warrant.
2. Whether the absence of field sobriety testing invalidated the probable-cause determination.
3. Whether the circumstances justified an immediate warrantless arrest under Montana Code Annotated § 46-6-311(1).

Disposition

affirmed
