PORTABLE BREATH TEST – New York Appellate Digest

The Second Department reversed defendant’s driving while intoxicated (DWI) conviction because the results of the portable breath test device (PBT) were allowed in evidence in the People’s direct case:

Generally, the result of a PBT, such as an Alco-sensor, “is not admissible to establish intoxication, as its reliability for this purpose is not generally accepted in the scientific community” … . Contrary to the trial court’s determination, isolated remarks during defense counsel’s opening statement did not open the door for the People to introduce incriminating testimony about the PBT result as part of their case-in-chief, particularly in the absence of appropriate limiting instructions … . We note that the opening remarks at issue, regarding the officer discarding the PBT “cap,” were at least partly offered in support of the defense theory that the defendant was not aware that he was the subject of a lawful arrest on the night in question, which theory was offered to undermine the charges of assault in the second degree and resisting arrest. Further, we find that the People adequately responded to this remark by eliciting the officer’s testimony that he disposed of the plastic cap because it was unsanitary, and this was standard procedure. Nonetheless, the People elicited testimony that, according to the PBT, the defendant’s BAC was .128%, significantly higher than the legal limit of .08%, before defense counsel had an opportunity to raise this issue during cross-examination … . Under these circumstances, it cannot be said that the defendant opened the door for the People to adduce evidence of an insufficiently reliable PBT result in order to prove the defendant’s intoxication … .

Thereafter, the trial court did not provide the jury with any limiting instructions regarding the PBT result …, but instead directed the jury to consider the PBT result as direct proof of the defendant’s intoxication. The court told the jury that the PBT was a “generally accepted instrument in determining blood alcohol content,” and that no scientific expert was necessary. This was error … . Under the circumstances, including the lack of evidence of admissible field sobriety tests, we find that this error was not harmless beyond a reasonable doubt.

The Second Department determined defendant’s DWI conviction must be reversed because evidence of the result of the portable breath test (PBT), which is generally inadmissible as unreliable, was allowed in evidence. The defendant had subsequently agreed to the chemical breath test, which can be admissible evidence at trial, but his breaths were so shallow during repeated attempts to administer the test that no results were obtained. The result of the PBT (which showed the presence of alcohol) was deemed admissible, not as proof of intoxication, but as evidence of defendant’s state of mind when the chemical breath test was administered (the People’s position was that defendant deliberately sabotaged the chemical test with shallow breaths). Although the PBT was ostensibly not admitted as proof of intoxication, the Second Department determined the jury would have taken it as such and, therefore, the probative value of the test result was outweighed by its prejudicial effect:

On appeal, the defendant contends that he was deprived of his right to a fair trial based on the County Court’s admission of the PBT results into evidence. We agree. Under the circumstances of this case, the probative value of the PBT evidence was outweighed by its prejudicial effect and, accordingly, should have been excluded … .

Generally, the result of a PBT “is not admissible to establish intoxication, as its reliability for this purpose is not generally accepted in the scientific community” … . Here, although the PBT evidence was not introduced for the purpose of proving intoxication, since the jurors were permitted to hear that the PBT detected the presence of alcohol, the County Court created an unacceptable risk that the jurors would improperly consider the PBT evidence for this impermissible purpose. This risk was enhanced both by the County Court’s determination to take judicial notice that the PBT was on the Commissioner’s conforming list and the State Trooper’s trial testimony that he was trained in the operation of the PBT device. The trooper’s testimony in this regard, which was directed towards the issue of whether the PBT was reliable for its intended purpose—the assessment of the defendant’s level of intoxication—was irrelevant to the defendant’s state of mind at the time he submitted to the chemical breath test at the State Police barracks. Thus, this testimony increased the risk that the jury would be unable to avoid considering the PBT evidence as proof of the defendant’s intoxication.
