Recently, this blog reported on the Minnesota Supreme Court’s opinion issued earlier this week on February 8, 2011 regarding the question of whether DWI urine tests are reliable. Specifically, the court did NOT decide the question of whether DWI urine tests are reliable, but instead chose to sidestep the issue on procedural grounds. The high Court refused to decide whether urine tests require a so-called Frye-Mack Hearing on their reliability.
