The last post in this blog described how crime lab reports are used in Ohio DUI / OVI cases. In a nutshell: a lab technician issues a report identifying the quantity of alcohol or drugs in a person’s blood or urine, and that report is given to the prosecutor. Ohio legislation requires the prosecutor to provide the report to the defense attorney. Ohio legislation, however, is not the only law impacting the use of these reports. The Constitutions of Ohio and the United States also provide limitations on the use of crime lab reports in Ohio DUI / OVI cases.
Defendants’ Confrontation Rights
In a criminal prosecution, defendants have the right to confront the witnesses against them. This right is guaranteed by the Sixth Amendment to the United States Constitution and Article I, Section 10 of the Ohio Constitution. Confrontation rights clearly apply to statements a witness makes during a trial: the defendant cross-examines that witness at the trial. But what about statements made by a witness before the trial?
The United States Supreme Court addressed this question in Crawford v. Washington (2004). In this case, the Court held confrontation rights apply to out-of-court statements which are “testimonial” in nature. A statement is “testimonial” if an objective person would reasonably believe the statement would be available for use at a later trial. For example, if a person makes a report to the police, that person’s statements to the police would be considered “testimonial”. According to Crawford, testimonial statements cannot be used in a criminal trial unless the accused has the opportunity to cross-examine the person who made the testimonial statement.
