Questione giuridica chiave
Whether the breathalyzer device was sufficiently identified and its calibration proved.
Decisione estratta
Yes. The device used on the night in question was sufficiently identified as the same device calibrated in March 2009, so its accuracy could be trusted.
Motivazione estratta
The lower court relied on multiple documents linking the internal and serial numbers. The defendant could comment on the evidence, and no serious doubt arose that would undermine the breath-test results.
