Accuracy and calibration certificates for breath-test machines are admissible without live testimony from the person who prepared them, the state Supreme Court has ruled, concluding the documents' admission does not violate a defendant's right to be confronted by his or her accuser.

The court in a unanimous decision affirmed the state Superior Court's ruling in a DUI case that breath-test machine certificates are "not testimonial," finding that the defendant's right to confrontation via the Sixth Amendment was not infringed.
