In Commonwealth v. Cormier, the defendant was arrested for an OUI and speeding in 2012. He agreed to take a Breathalyzer test. The results of the test showed he was above the statutory limit for alcohol consumption.
During discovery, the defendant asked for the manual for the particular Breathalyzer machine that had given results in his case. The Office of Alcohol Testing (OAT) responded there was no manual. In response, the defense asked to exclude the breath test under 501 Code Mass. Regs § 2.04(f), which requires OAT to develop and maintain an operator's manual.
The defense asked for an evidentiary hearing. At the hearing, an OAT supervisor testified that the machine in question was new and had only been introduced the year before the defendant's arrest and that it was in use throughout the state. She explained the machine had two parts. The information related to the first part, the inner workings that measured breath, wasn't in a manual because the manufacturer had a proprietary interest in the technology. The second part related to state-specific software that had to be installed because of different breath test requirements across the country.
