Citation: 127 Nev. Adv. Op. No. 84
Docket Number: 
State: Nevada
Issuer: Nevada Supreme Court
Date: December 29, 2011

State v. Dist. Court (Armstrong) Annotate this Case Justia Opinion Summary After real party in interest Bobby Armstrong's vehicle collided with another vehicle, the State charged Armstrong with driving under the influence causing death and/or substantial bodily harm. A single blood sample was taken from Armstrong more than two hours after the collision. The district court granted Armstrong's motion to exclude the blood alcohol test in part, concluding that the retrograde extrapolation that the State would have to use to determine Armstrong's blood alcohol level at the time was driving would be unfairly prejudicial in this case. The State subsequently filed a petition for a writ of mandamus to compel the district court to admit the excluded evidence. The Supreme Court denied the writ, holding (1) although retrograde extrapolation evidence is relevant in a prosecution for driving under the influence, under certain circumstances such evidence may be unfairly prejudicial and therefore inadmissible; and (2) under the circumstances of this case, the district court did not manifestly abuse its discretion in excluding the retrograde extrapolation.
