Reported Case:

People v. Heilman, 52 P.3d 244 (Colo. 2002)
Synopsis: Representing a criminally accused party, Daniel E. Quinn won a suppression of evidence case in the District Court of Larimer County by establishing to the trial court's satisfaction that certain police conduct involving an automobile search constituted a violation of the defendant's 4th Amendment rights. Unable to continue the prosecution of the defendant absent the suppressed evidence, the District Attorney appealed the trial court's order to the Colorado Supreme Court. The defendant was again represented by Daniel E. Quinn on appeal to the state's highest court. After full briefing and argument by both sides, the Colorado Supreme Court unanimously upheld the original decision in favor of the defendant. The District Attorney dismissed the case. People v. Heilman continues to be routinely cited by legal practitioners as helping to establish in Colorado law when a police contact is not a consensual encounter, but rather a search entitled to the Constitutional protections of the 4th Amendment.
