Facts

The Defendant was stopped by an officer after driving in the wrong direction on a highway on-ramp. The officer observed signs of impairment and administered a Standardized Field Sobriety Test (FST), including a Horizontal Gaze Nystagmus (HGN) test. Based on the results, the Defendant was arrested and later submitted to a breath alcohol test, which indicated a blood alcohol concentration (BAC) of 0.09% (paras 7-8).

Procedural History

• Santa Fe County Magistrate Court: The Defendant was convicted of driving while under the influence in violation of NMSA 1978, § 66-8-102 (para 7).
• First Judicial District Court: On appeal, the district court conducted a trial de novo. The court excluded the results of the HGN test, ruling that the State failed to establish the scientific validity of the test under the standards set in State v. Torres and State v. Alberico (paras 8-10).

Parties' Submissions

• Plaintiff-Appellant (State): Argued that the HGN test results were admissible as scientific evidence and that their expert, Dr. Marcelline Burns, was qualified to establish the test's validity and reliability. The State contended that the district court erred in requiring testimony from a medical doctor to validate the HGN test (paras 10, 16-17, 24).
• Defendant-Appellee: Argued that the State failed to meet the evidentiary reliability standard required for the admission of scientific evidence. The Defendant challenged the qualifications of the State's expert and the scientific basis of the HGN test (paras 10, 16-17).

Legal Issues

• Whether the results of the Horizontal Gaze Nystagmus (HGN) test were admissible as scientific evidence under the standards established in State v. Torres and State v. Alberico.
• Whether the State's expert, Dr. Marcelline Burns, was qualified to establish the scientific validity of the HGN test.

Disposition

• The Court of Appeals affirmed the district court's decision to exclude the results of the HGN test (para 28).

Reasons

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

• The Court emphasized that under State v. Torres, scientific evidence must meet the evidentiary reliability standard, which includes demonstrating the scientific validity of the technique used (para 12).
• The HGN test was designed to discriminate between BAC levels above and below statutory limits, not to measure driving impairment directly. The State failed to establish the necessary scientific foundation linking HGN results to impairment (paras 13-15, 20).
• The district court did not abuse its discretion in requiring testimony from an expert capable of explaining the physiological and pharmacological basis of the HGN test. Dr. Burns, a behavioral psychologist, was not qualified to provide this evidence (paras 16-18, 23-24).
• The Court noted concerns about the potential for false positives and the lack of detailed scientific explanation regarding the correlation between HGN cues and BAC levels (paras 20-22).
• The Court also observed that the Motor Vehicle Code does not authorize convictions based on non-chemical BAC tests like the HGN test, further supporting the exclusion of the evidence (paras 25-27).
