OPINION OF THE COURT
Memorandum.
The order of the Appellate Division should be reversed and a new trial ordered.
As a foundational requirement for the admission of breathalyzer test results in a prosecution under Vehicle and Traffic Law § 1192, the People must introduce evidence from which the trier of fact could reasonably conclude, inter alla, that the testing device was in proper working order at the time the test was administered to the defendant (People v Todd,
People v Gower (
We are presented in this case with a record devoid of any
Thus, in the absence of any evidence from which the trier of fact could reasonably conclude that the test results were derived from a properly functioning machine using properly constituted chemicals, it was error to admit the test results and a new trial is required. We note that, on the state of this record, we have no occasion to determine what nature, quantity and quality of proof is required to establish these foundational requirements, because there was no such proof in this case.
The other argument raised by defendant in the lower courts, that his prior conviction under Vehicle and Traffic Law § 1192 (3), entered on his uncounseled guilty plea, was not a valid predicate for elevating the present charges to felonies, appears to have been abandoned on this appeal and, in any event, was properly rejected by the courts below. We have not been asked to consider the propriety of the trial court’s ruling that certain certificates, offered by the People in an effort to establish a proper foundation for the admission of the breathalyzer test result, were inadmissible under CPLR 4518. For that reason, and because those certificates are not in the record before us, we do not reach the issue.
Chief Judge Wachtler and Judges Meyer, Simons, Kaye, Alexander, Titone and Hancock, Jr., concur in memorandum.
On review of submissions pursuant to section 500.4 of the Rules of the Court of Appeals (22 NYCRR 500.4), order reversed, etc.
