City of Helena v. O'Connell
Annotate this Case
The Supreme Court affirmed the order of the district court upholding the denial of Defendant’s motion to dismiss her driving under the influence (DUI) charge, holding that Montana’s statutory protections against double jeopardy did not bar Defendant’s charge.
In 2016, Defendant pleaded guilty to careless driving. After reviewing Defendant’s toxicology report, the Helena Attorney’s Office additionally charged Defendant with DUI. Defendant moved to dismiss her DUI charge as a subsequent prosecution barred by Mont. Code Ann. 46-11-504(1). The municipal court denied the motion to dismiss. The district court upheld the denial of Defendant’s motion to dismiss. Thereafter, Defendant pleaded guilty to negligent endangerment pursuant to a plea agreement, preserving her right to appeal. The Supreme Court affirmed, holding (1) Mont. Code Ann. 46-11-503 applied in this case; but (2) because no probable cause existed to charge Defendant with DUI before resolution of her careless driving charge, section 46-11-503 did not bar the subsequent DUI charge from prosecution.
