Facts

A police officer responded to a report of a man staggering in a parking lot, attempting to unlock multiple vehicles, and eventually driving away in a van. The officer traced the van to a residence, observed signs of recent vehicle use, and witnessed the Defendant inside the home exhibiting signs of severe intoxication. The officer entered the home, questioned the Defendant, and arrested him for aggravated driving while intoxicated (DWI) after observing further evidence of intoxication (paras 2-3).

Procedural History

• Municipal Court: The Defendant was convicted of aggravated DWI after the court denied his motion to suppress evidence and ruled the arrest was lawful.
• District Court: The Defendant appealed, and the district court dismissed the DWI charge, finding the arrest violated the misdemeanor arrest rule (paras 1, 3-4).

Parties' Submissions

• City of Santa Fe (Appellant): Argued that the misdemeanor arrest rule did not apply to DWI investigations and that the arrest was lawful under probable cause and exigent circumstances. Alternatively, it contended that the "in presence" requirement of the misdemeanor arrest rule was satisfied (paras 3, 4).
• Defendant (Appellee): Asserted that the arrest violated the misdemeanor arrest rule, as the officer did not witness the alleged offense, and moved to suppress evidence based on constitutional violations under the Fourth Amendment and the New Mexico Constitution (paras 3-4).

Legal Issues

• Does the misdemeanor arrest rule, with its "in presence" requirement, apply to DWI investigations?
• Was the Defendant's warrantless arrest supported by probable cause and exigent circumstances?

Disposition

• The Supreme Court of New Mexico reversed the district court's dismissal of the DWI charge and remanded the case for further proceedings (paras 17-18).

Reasons

Per Serna J. (Daniels C.J., Maes, Bosson, and Chávez JJ. concurring):

• The misdemeanor arrest rule, which requires an officer to witness a misdemeanor offense to make a warrantless arrest, is a common law principle designed to prevent undue harm from custodial detentions for minor crimes. However, the rule is outdated and does not align with the public safety concerns inherent in DWI cases (paras 6-7, 11-12).
• DWI is not a "minor crime" but a significant public safety issue with potentially deadly consequences. The Court emphasized the compelling state interest in deterring and prosecuting DWI offenses (paras 13-14).
• The Court noted that the time-sensitive nature of DWI evidence, such as blood alcohol levels, necessitates prompt investigation and action. Requiring officers to observe the offense directly would hinder effective enforcement and risk the loss of critical evidence (paras 15-16).
• The Court held that the misdemeanor arrest rule does not apply to DWI investigations. Instead, warrantless arrests for DWI must be supported by probable cause and exigent circumstances, similar to felony investigations (paras 16-17).
• The district court erred in dismissing the charge based on the misdemeanor arrest rule. The case was remanded to determine whether the arrest met the constitutional requirements of probable cause and exigent circumstances (paras 17-18).
