Breath test evidence is heavily contested in Massachusetts OUI trials. When someone takes a breath test, as a Massachusetts OUUI Lawyer, we attempt to exclude the results from evidence as being unreliable. But what happens if the machine does not register, is the failed attempt to take a breath test admissible and under what circumstances. That was the issue in the case of Commonwealth v. Daigle, the Massachusetts Appellate Court answered this question.
A failed breath test is admissible in certain circumstances. It is well settled that a defendant refusing to take a breath test is not admission against them during an OUI trial. However, if a defendant signs a consent form to take a breath test, a machine malfunction or other errors may be admissible, In the case of Commonwealth v. Curley, police officers alleged that the defendant was purposely blowing into a breathalyzer machine incorrectly as to inhibit the machine from producing a reading. Because the defendant in that case signed a consent form, the jury could infer from his actions that he waa trying to avoid giving a sample while appearing to try and take the test.
