Destruction of evidence by the government can violate a defendant’s right to due process of law. Due process violations often lead to cases being dismissed. Using dismissal as a remedy is based on the principle that denying a defendant access to evidence can make a trial unfair.

An implied consent law similar to Ohio’s was recently found to be unconstitutional by the Georgia Supreme Court.
Just as Hollywood has produced some good movies in trilogies, the United States Supreme Court has produced some good case law in trilogies. The Court addressed the right to confront crime lab analysts with the trinity of Bullcoming, Melendez-Diaz and Williams. On the issue of the need for a warrant to draw blood from a DUI suspect, two-thirds of the triad have been completed: McNeely and Birchfield. The triumvirate is about to be consummated with Mitchell v. Wisconsin.
