Case Name: People v. McKown (.pdf) (link to case summary)
Court: Supreme Court of the State of Illinois
Date Decision Filed: 2/19/2010
This important DUI case can be boiled down to two points: (a) the horizontal gaze nystagmus (HGN) field sobriety test satisfies the Frye test; and (b) HGN evidence will only come into evidence at trial if NHTSA requirements are complied with.
