State v. TannerState v. Tanner
William R. Tanner was charged by bill of information with negligent homicide in violation of
On November 8, 1980, defendant was involved in an automobile accident which resulted in the death of a passenger traveling in another vehicle. The state troopers who investigated the accident noticed alcоhol on defendant‘s breath and an auto-intoximeter breath analysis test was administered. Defendant‘s reading was 0.189% which is over the level presumptive of being under the influence of alcohol.
Generally, questions оf admissibility, relevance and weight of evidence are properly resolved at trial on the merits, not by pretrial motions. See State v. Garnier, 261 La. 802, 261 So.2d 221 (1972). However, the evidence in question in this case, the results of a chemical test, can give rise to a presumption that the person was under the influence of alcoholic beverages.
In the present case, defendant sought to raise objection to the admissibility of the chemical test results by way of a motion to suppress.
Now that we have established that the question of admissibility was properly raised by a motion to suppress, the merits of that motion must be reviewed. When the legislature authorized the chemical analysis of a motorist‘s blood and created a statutory presumption of intoxication in the event that his blood contained the requisite percent of alcohol, it conditioned the validity of the chemical test upon its having been performed according to methods approved by the Department of Public Safety.
The first question presented is whether or not the recertification form, used by the state as prima facie proof of accuracy, was deficient because it failed to bear affirmative and detailed prоof that the “known alcohol standard” used to calibrate the auto-intoximeter was pure and unadulterated. Specifically, did the state prove that the Department of Public Safety had promulgated sufficient guidelines to guarantee the accuracy of the auto-intoximеter test result.
In State v. Goetz, supra, the defendant contested the admissibility of a photo-electric intoximeter (P.E.I.) test result. The only evidence that the state offered as prima facie proof of the machine‘s accuracy was a copy of its recertification form which containеd a statement that the ampule lot used in the test had been spot checked for performance. This was in accord with the applicable regulations in effect at the time. See Rule 1, 4(c), 4(d), 4 La. Register 390, 391 (1978). This court did not accept the recertification form as proof of сhemical accuracy because the Department of Public Safety had not, at that time, established sufficient criteria to insure the reliability of a spot check of the P.E.I. ampules and because the state did not establish the qualifications of the person who performеd the spot check. The photo-electric intoximeter is dependent upon the proper chemical composition, strength, and volume of the ampules used in the machine for its accuracy. If the chemicals involved in the test are of inferior quality, it is possible that а practically conclusive presumption of guilt would be brought to bear against an innocent person. See Goetz, supra. See Graham, supra; R. Donigan, Chemical Test and the Law, 71, 278-80 (2d ed. 1966).
It is significant that the photo-electric intoximeter involved in Goetz and the auto-intoximeter used here are two different machines, and the regulations concerning the maintenanсe procedure of each are different. See Rules, 4 La. Register 390-93 (1978). However, in State v. Morrison, supra, this court noted that while most of the jurisprudence concerning the requirements
The pertinent evidence adduced at the suppression hearing was the auto-intoximeter‘s recertification form and the Department of Public Safety regulations. The Department of Public Safety has promulgated detailed regulations in order to insure the accuracy of the auto-intoximeter. Concerning maintenance, a recertification procedure is used whereby the machine is recalibrated at four-month intervals. The regulations in effect at the time defendant was tested, concerning the actual maintenance checks performed, called for the running of a “known alcohol standard” in order to check the machine‘s calibration. However, those regulations did not provide any criteria to determine if a pure and unadulterated “known alcohol standard” was used in this maintenance procedure. See Rule 6(c), 4 La. Register 390, 391-92 (1978). Also, it was not required that the recertification form, issued after the maintenance was complete, contain any affirmative proof that the “known alcohol standard” used was рure and unadulterated; yet, the regulations designated that this form was to be the prima facie proof of the auto-intoximeter‘s accuracy. See Rules 1 & 6(c), id. at 390-92. Clearly, the regulations called for the use of a ”known alcohol standard” in recalibration. The conclusion that the alcohоl standard used was to be known implies that someone had determined this to be so; however, the regulations are deficient because they do not designate how, when or by whom this was to be determined.9 Therefore, from the face of the regulations themselves, it appears that the testing of the “known alcohol standard” for purity was a necessary step in the maintenance procedure in order to insure accuracy, and a recertification form, without affirmative proof of purity, would not be acceptable proof of the accuracy of the auto-intoximeter test result. Consequently, the state failed to prove that the maintenance regulations were sufficient to insure the accuracy of the chemical test result. Moreover, the state did not offer any additional evidence to establish that, despite thе lack of adequate maintenance regulations, the machine‘s result was nonetheless accurate. This could have been done by producing evidence attesting to the purity of the “known alcohol standard” used to recalibrate the machine. Because of this cоnclusion, we do not reach the issue of whether or not the state has strictly complied with the remainder of the regulations promulgated by the Department of Public Safety. Hence, the motion to suppress was correctly granted by the trial court.
DECREE
For the reasons assigned, judgment of thе court of appeal is reversed; judgment of the trial court is reinstated; and the case is remanded to the trial court for further proceedings.
