376 P.3d 858
N.M.2016Background
- Officer Rempe queried the MVD database via his patrol car MDT using the vehicle's plate and received an "unknown" insurance-compliance status for the vehicle Joann Yazzie was driving.
- Based solely on the "unknown" result, Officer Rempe initiated a traffic stop; further investigation led to Yazzie's arrest for DWI and failure to maintain insurance.
- MVD witness Walter Martinez testified the MVD/insurer-matching database is updated nightly, that an "unknown" status commonly reflects a post-notice interim period before registration suspension, and that a four-month sample showed ~89% of "unknown" vehicles were ultimately uninsured or had registrations suspended.
- The district court denied Yazzie's motion to suppress, concluding the "unknown" result gave reasonable suspicion of an MFRA violation.
- The Court of Appeals reversed, holding an "unknown" return without officer-specific knowledge of the statistics did not supply reasonable suspicion. The New Mexico Supreme Court granted certiorari.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Yazzie) | Held |
|---|---|---|---|
| Whether an MVD database report of an "unknown" insurance-compliance status supplies reasonable suspicion to stop a vehicle for possible MFRA violation | An "unknown" MVD status is produced by a statutorily maintained, reliable database; given the high empirical likelihood that "unknown" means uninsured, it supplies objective reasonable suspicion to stop and investigate | An "unknown" designation is ambiguous and statistical group data cannot alone create individualized reasonable suspicion to stop a specific driver | Yes. The Court held an "unknown" MVD status, in the absence of evidence the database is unreliable, provided objective reasonable suspicion to stop the specific vehicle |
| Whether generalized statistical evidence about the group of "unknown" vehicles can support the required particularized suspicion of the individual stopped | The MVD statistics about the high probability that an "unknown" vehicle is uninsured are admissible to show reliability of the database; particularization exists because the MDT query tied the plate to that specific vehicle | Group statistics cannot substitute for individualized facts tying the defendant to criminal conduct; relying on such probabilities risks guilt-by-association | Yes. The Court held the stop was particularized: the MDT query linked the specific plate/vehicle to the MVD record, and absent proof the database was unreliable, the statistics support reasonable suspicion for that individual stop |
