COMMONWEALTH vs. MARY E. LIVERS (and a consolidated case [Note 1]).

WILKINS, J. Each defendant, charged with operating a motor vehicle while under the influence of alcohol, was successful in persuading a judge in the jury session of the Hingham District Court to allow a motion to suppress breathalyzer test results. The breathalyzer tests were conducted, respectively,

Page 557

in March and July, 1991. In September, 1992, in separate rulings, the same motion judge concluded that, although the breath testing machines had been properly tested, the test results could not be admitted at trial because there were no State regulations in effect concerning the periodic testing of such machines when the breathalyzer tests were conducted.

The Commonwealth successfully obtained leave from a single justice of this court to take interlocutory appeals from the allowance of the defendants' motions to suppress. The single justice directed that the appeals be consolidated and entered in this court. We conclude that the judge erred in ruling that there was a statutory requirement that regulations be issued concerning the periodic testing of breathalyzer machines. All that was and is required is that there be a periodic testing program and that the program be followed with respect to the testing device used in a particular case.

This court held in Commonwealth v. Barbeau, 411 Mass. 782 (1992), that the Commonwealth had to prove the existence of, and compliance with, a periodic testing program for breathalyzer machines before the results of a breathalyzer test may be admitted in evidence. The court said that the testing program must be carried out in accordance with methods approved by the Secretary of Public Safety (Secretary). Id. at 784. The Secretary had issued a regulation requiring the office of alcohol testing (OAT) to devise a program for the periodic testing of certified breath testing devices. We did not rule that the test results should be suppressed on the ground that there was no regulation setting forth in detail a periodic testing program, but rather we ruled as we did because the Commonwealth had failed to prove that there was a periodic testing program and that, as to the machine involved, the police had complied with the requirement of any such program. Id. at 786. On February 13, 1992, two days after the release of the Barbeau opinion, the Secretary's regulations concerning the periodic testing of breath testing machines (February, 1992, regulations) became effective.

In Commonwealth v. Smith, 35 Mass. App. Ct. 655 (1993), the defendant had taken a breathalyzer test in March, 1991, approximately eleven months before the February, 1992, regulations were issued. At that time, 501 Code Mass. Regs. Section 2.41 (1987) stated simply that the OAT must "devise a program for the periodic testing of certified breath testing devices and simulators." See id. at 661 n.7. In the Smith case, the court stated that it was shown that the OAT had an operator's manual that concerned the use, maintenance, and testing of breath testing devices and that the Secretary had "enshrined in [the February, 1992, regulations] what the manual had already required." Id. at 661. There was also testimony that the device used had been tested conformably with the criteria later incorporated in Section 2.41. The Appeals Court, citing Morris v. Commonwealth, 412 Mass. 861 (1992), which we shall discuss later, upheld the denial of Smith's motion to suppress the results of his breathalyzer tests. Smith, supra.

It does not appear that Smith argued that the absence of detailed regulations concerning breathalyzer testing in effect at the time of his testing and at the time of the testing of the breathalyzer machine required the exclusion of his test results. He simply argued unsuccessfully that the Commonwealth had failed to establish that the breathalyzer machine had been tested conformably with a periodic testing program. Id. at 660.

The third case concerning an attempt to suppress evidence obtained by a breathalyzer machine because of allegedly inadequate testing of the machine presents a slightly different situation. In Morris v. Commonwealth, supra, the breathalyzer tests were conducted after the February, 1992, regulations concerning testing and other matters had been issued, but all the periodic testing of the machine's calibration had occurred before the February, 1992, regulations had been issued. Id. at 866 n.8. Morris argued that the Secretary had unlawfully purported in the February, 1992, regulations to delegate responsibility for periodic testing to the police. He also challenged the February, 1992, regulations on the

Page 559

ground that they did not meet what he asserted was the statutory mandate for periodic testing. The court rejected both arguments. Again, no claim was made that the absence of regulations concerning periodic testing in effect at the time the machine was tested made the test results inadmissible.

There is good reason why persons charged with operating motor vehicles while under the influence of alcohol have not previously argued that the absence of regulations concerning periodic testing of breathalyzer machines invalidates all breathalyzer test results. The statute does not require regulations on that subject. Section 24K of G. L. c. 90 (1992 ed.), the first paragraph of which is set forth in the margin, [Note 2] requires that there be regulations concerning the administration of breathalyzer tests to individuals, but Section 24K does not require that there be regulations concerning periodic testing of breath testing devices. Section 24K requires only that the Secretary "establish . . . a periodic certification program for such breath testing devices."

The judge found that the testing of the breathalyzer machines used in the two cases before us met the requirements of the subsequently adopted February, 1992, regulations, but that, because those regulations were not in effect when the tests of the breathalyzers were conducted, the tests did not meet the demands of the statute. These rulings were wrong because, as we have said, no regulations were required on the subject of periodic testing. The requirement is that there be a program for periodic testing of breath testing devices. That

Page 560

program may be expressed in regulations, as it now is, but it need not be.

The orders allowing the defendants' motions to suppress are vacated, and the cases are remanded to the District Court for further proceedings. It does not appear on the record that either defendant has asserted some further ground for suppressing their breathalyzer test results, and if none has been asserted, orders should be entered denying the motions to suppress. [Note 3]

So ordered.
