Facts

A Deputy Marshal from the Town of Mesilla observed a driver exhibiting erratic behavior, including crossing into the oncoming lane, while driving within the City of Las Cruces. The Deputy Marshal stopped the driver, conducted preliminary sobriety tests, and called for a Doña Ana County sheriff's deputy, who later arrived, conducted field sobriety tests, and arrested the driver for DWI. The Deputy Marshal was not cross-commissioned or authorized to act outside his jurisdiction (paras 2-3).

Procedural History

• District Court, date unspecified: The court suppressed the evidence and dismissed the DWI charge, ruling that the Deputy Marshal lacked jurisdiction to stop the driver outside the Town of Mesilla (para 3).

Parties' Submissions

• Appellant (State of New Mexico): Argued that the Deputy Marshal's stop was justified as a lesser intrusion than a citizen's arrest, which he was entitled to make, and that his actions were reasonable and within his authority (para 1).
• Appellee (Defendant): Contended that the Deputy Marshal lacked jurisdictional authority to stop him outside the Town of Mesilla, rendering the evidence inadmissible (para 3).

Legal Issues

• Whether a deputy marshal, acting outside his jurisdiction without cross-commission or fresh pursuit, may initiate a traffic stop for erratic driving that constitutes a breach of the peace.
• Whether evidence obtained by a sheriff's deputy following such a stop is admissible.

Disposition

• The Court of Appeals reversed the district court's decision to suppress the evidence and dismiss the charges and remanded the case for trial (para 12).

Reasons

Per Robinson J. (Alarid and Pickard JJ. concurring):

• The Court held that while a municipal officer's official powers are limited to their jurisdiction, they retain the common law right to make a citizen's arrest or detention for breaches of the peace, such as driving under the influence (paras 4-5, 9).
• The Deputy Marshal's actions were reasonable and akin to those of a private citizen, as he observed erratic driving that posed a public safety risk and did not use powers unavailable to a private citizen (paras 6-9).
• The evidence used to arrest the Defendant was independently obtained by the sheriff's deputy, who had jurisdictional authority, making it admissible (paras 7, 11).
• The Court cited precedent from New Mexico and other jurisdictions supporting the principle that law enforcement officers acting outside their jurisdiction may act as private citizens in certain circumstances (paras 5-11).
