Melendez-Dias Results in Massachusetts DUI Defense Win
In the recent Massachusetts DUI case of Commonwealth v. Parmenter, (November 24, 2009), Marlborough District Court Judge Noonan excluded evidence regarding the DUI defendant’s alcohol levels which were determined from blood drawn while the defendant was airlifted from the scene of an OUI accident to the hospital. The blood alcohol evidence was excluded based on the Supreme Court’s decision in Melendez-Dias v. Massachusetts, 129 S. Ct. 2531 (2009).
Judge Noonan ruled that the blood alcohol evidence will be inadmissible at Parmenter’s DUI trial unless the Commonwealth produces the medical personnel who drew the blood. The laboratory personnel who tested the blood should also be required to testify.
In Melendez-Dias v. Massachusetts, the Supreme Court held that the introduction of laboratory certifications without making available the scientist who conducted the laboratory tests violates the confrontation clause of the U.S. Constitution which gives criminal defendants the right to confront and cross-examine adverse witnesses. The Melendez-Dias decision may prove to be a powerful tool in Massachusetts DUI cases.
