OPINION
{1} In 1993, thе Implied Consent Act was amended so that motor vehicle operators are deemed to consent to blood or breath alcohol tests that are “approved by the scientific laboratory division of the department of health.” NMSA 1978, § 66-8-107(A) (1993). Department of Health Regulation 12.1.1 requires breath samples to be collected only after “the subject has been undеr continuous observation for at least 20 minutes prior to collection of the first breath sample.” 7 NMAC 33.2.12.12.2.1 (Oct. 31, 1996). The question we address in this case is whether a breath alcohol test taken after the Defendant was continuously observed for only fifteen minutes is admissible in her criminal case for driving while intoxicated (DWI). We hold that it is not and reverse.
{2} Defendant raises two other issues on appeal in addition to the issue concerning the admission of the test results. We do not address the prosecutor-misconduct issue because it is not certain to arise on retrial. We summarily answer the issue concerning alleged error in the bind-over order for felony DWI when there was no proof of prior DWI convictions presented to the magistrate: “a probable сause showing regarding the existence of three prior [DWI] convictions was not required in order to support jurisdiction in the district court.” State v. Anaya,
FACTS
{3} Defendant’s vehicle was stoppеd for erratic driving. Upon observing classic signs of intoxication, the officer placed Defendant under arrest and transported her to the Sheriff’s Office for a breathalyzer test. The officer observed Defendant while she was in his patrol car and again after they arrived at the Sheriff’s office. At the station, however, Defendant left the officer’s observation when she wаs permitted to use the restroom. The officer testified that this happened about fifteen to twenty minutes before the test. When Defendant returned from the restroom, the officer asked her if she was okay, and Defendant did not indicate that anything was wrong. The officer claimed in his testimony that Defendant was within his observation the entire twenty minutes before the test despite Defendаnt leaving to go to the bathroom. Nonetheless, the officer admitted that he did not know whether Defendant burped, belched, or vomited while she was in the bathroom. The officer explained that the continuous observation requirement is important to ensure that DWI suspects do not burp, belch, or vomit prior to the administration of the test, as that can lead to an erronеous test result. Defendant’s test results showed a breath alcohol concentration of .19, .18, and .18.
{4} At the time the test results were offered into evidence at trial, defense counsel objected that they were inadmissible. Specifically, defense counsel argued that the continuous observation period required by statute and regulation was not met when Defendant was allоwed to use the restroom unaccompanied by the officer within twenty minutes prior to the administration of the test. The trial court overruled the objection, the results were admitted into evidence, and Defendant was convicted. On appeal, Defendant contends that the test results were improperly admitted into evidence because the officer failed to strictly comply with the twenty-minute continuous observation period by permitting Defendant to be out of his presence for the time it took for her to use the restroom, which may have been as close as fifteen minutes before the test. DISCUSSION
{5} We hold that the test results were improperly admitted into evidence due to the violation, by as much as five minutes, of the twenty-minute continuous observation period. We review rulings upon the admission or exclusion of evidence under an abuse of discretion standard, see State v. Hoeffel,
I. Statutory Structure
{6} Department of Health Regulation 12.1.1 states:
Two breath samples shall be collected and/or analyzed by certified Operators or Key Operators only, and shall be end expiratory in composition. Breath shall be collected only after the subject has been under continuous observation for at least 20 minutes prior to collection of the first breath sample. If during this time the subject regurgitates or introduces any foreign substance suspected of containing alcohol into his mouth or nose, another 20 minutes observation period must be initiated. The two breath samples shall be taken not more than 15 minutes apart. If the difference in the results of the two samples exceeds 0.02 grams per 210 liters (BrAC), a third sample of breath or blood shall be collected and analyzed. If the subject declines or is physically incapable of consent for the second and/or third samples, it shall be permissible to collect and/or analyze fewer samples.
7 NMAC 33.2.12.12.2.1. This regulation was promulgated pursuant to the authority of NMSA 1978, § 24-1-22 (1981), which allows the “scientific laboratory division of the health and environment department [department of health]” to promulgate and approve methods of testing people under the influence of alcohol or drugs and to estаblish criteria for testing methodology and collection of breath samples.
{7} If Section 24-1-22 were the only statute touching on the matter at issue in this case, it may be that suppression of the results of Defendant’s breath alcohol tests taken in violation of the regulation might not be required. However, the Implied Consent Act and the DWI statutes underwent substantial revision in 1993 as part of a comprehensive legislative effort to address this state’s DWI problem. See 1993 N.M.Laws, ch. 66 (amending, inter alia, NMSA 1978, §§ 66-8-102, -102.1, -107, & -109 to -112 (1993)). All parts of this statute must be read together and each part must be considered in relation to the others to determine whether substantial compliance with the twenty-minute observation period is sufficient. See Citizens for Incorporation, Inc. v. Board of County Comm’rs,
{8} Section 66-8-110(A) provides that the “results of a test performed pursuant to the Implied Consent Act ... may be introduced into evidence in any civil action or criminal action arising out of the acts alleged to have been committed by the person tested].]” (Emphasis added.) Prior to its amendment in 1993, the Implied Consent Act, Section 66-8-107(B), stated that a “test of blood or breath shall be administered at the direction of a law enforcement officer” when there was probable cause to believe a person was driving while intoxicated. NMSA 1978, § 66-8-107(B) (1985). Following its amendment, Section 66-8-107(B) states that a “test of blood or breath or both, approved by the scientific laboratory division of the department of health pursuant to the provisions of Section 24--1-22 NMSA 1978, shall be administered at the direction of a law enforcement officer” when there is probable cause to believe a person was driving while intoxicated. (Emphasis added.) Similarly, Section 66-8-107(A) provided, before its amendment, that persons operating motor vehicles within the state were deemed to have consented to tests as determined by law enforcement officers. Hоwever, after the 1993 amendment, that same section limited the tests to which drivers are deemed to consent to those approved by the department of health. Compare § 66-8-107(A) (1985) with § 66-8-107(A) (1993).
{9} Thus, following the 1993 amendments to the DWI laws, in order for persons to be deemed to have given their consent to blood or breath alcohol tests, and in order for those test results to be admitted intо evidence, the tests must have been taken in accordance with department of health regulations. In the case of breath alcohol tests, these regulations include the twenty-minute waiting period of Regulation 12.1.1. In this case, Regulation 12.1.1 was not complied with and thus, according to the statutes, it appears that Defendant’s breath alcohol test results should not havе been admitted into evidence.
II. State v. Watkins
{10} In State v. Watkins,
{11} Now, however, we are faced with DWI statutes that have been substantially amended. The addition of language concerning breath and blood alcohol testing in accordance with department of health regulations in the implied-сonsent statute, § 66-8-107, as well as the admissibility-of-evidence statute, § 66-8-110, convinces us that the legislature intended that compliance with these regulations would be a condition precedent to admissibility. In this regard, we join all the states that have been called to our attention by the briefs and hold that failure to comply with the applicable waiting period precludes the admission of breath alcohol test results into evidence. See Department of Highway Safety & Motor Vehicles v. Farley,
{12} The purpose of complying with the waiting period requirements for breath alcohol tests is to еnsure the accuracy of these tests. See Boughner,
III. State v. Jones and State v. Bearly
{13} Our decision today raises a question whether our holding will be consistent with our recent case of State v. Jones,
{14} In this case, we hold that no prejudice need be shown. That is because the requirement of compliance with applicable regulations is explicitly a part of the statute that permits the tests into evidence. See §§ 66-8-107(A) & (B) & -110(A). Neither Jones nor Bearly involved the same statutory structure as in this case. In fact, the statutе in Bearly was not even part of the DWI statutes. Moreover, in Jones, the statute at issue simply allowed the defendant to take an additional breath or blood alcohol test by a person of the defendant’s own choosing. The statute said nothing about the remedy if the additional test was not allowed. See § 66-8-109(B).
{15} We are supported in choosing the remedy of suppression in this case by the legislature’s having enacted the 1993 amendments aware of Watkins and also aware of one other decision, State v. Wilson,
IV. State v. Rivera and Substantial Compliance
{16} The State urges that we apply the doctrine of substantial compliance to this case and hold that there was sufficient evidence to support the district court’s decision to admit the breath alcohol test results. The State explains that the officer substantially complied with the state regulations by observing Defendant for forty minutes prior to the test, during-which time he did not see her belch, vomit, or burp. Moreover, the State argues that our application of the doctrinе of substantial compliance in State v. Rivera,
{17} In Rivera, the defendant raised a sufficiency of the evidence issue because, among other things, there was insufficient evidence that he was continuously observеd for twenty minutes as required by the state regulations. See id. ¶4,
{18} While we do not retreat from Rivera, we point out that in this case there was no testimony that the purpose of the regulation was satisfied. In fact, the officer here testified that he did not observe Defendant while he was having the car towed, while Defendant was in the back seat of his vehicle and he was driving it, and while she used the restroom. Moreover, it appeared that the twenty-minute period was satisfied in Rivera. Here, the officer admitted that Defendant was allowed to use the restroom unobserved at a time that cоuld have been only fifteen minutes before the test.
{19} When the regulation requires twenty minutes, we are reluctant to say that fifteen minutes will be sufficient. See Lane v. Lane,
{20} Thus, we do not find support in either the out-of-state cases or in the evidence in this case for relaxing the twenty-minute requirement to a period of fifteen minutes. We do not hold that substantial compliance might not be sufficient if the matter at issue was the continuous observation requirement and the officer glanced down periodically to do paperwork, but testified that he or she would have been able to tell if the defendant “regurgitate[d] or introduce[d] any foreign substance suspected of containing alcohol into his mouth or nose,” as required by Regulation 12.2.1. That issue is not in front of us. Here, we are concerned with whether a fifteen-minute observation period is sufficient when the regulations require twenty minutes. We hold that it is not.
{21} The State argues that the error of admitting the tеst results was harmless because there was overwhelming evidence that Defendant was driving while intoxicated. The State points to her erratic driving; her appearance, including the smell of alcohol, bloodshot eyes, and slurred speech; and her failing several field sobriety tests. However, we agree with the analysis in McCaslin,
CONCLUSION
{22} Defendant’s conviction' for DWI is reversed, and this case is remanded for a new trial.
{23} IT IS SO ORDERED.
