Even the defense attorney agrees that Janet Sue Shriner was "highly intoxicated" when she crashed head-on into a car, injuring its driver in Burnsville.
But a Dakota County judge tossed the evidence of her intoxication out of court and dismissed charges of first-degree drunken driving and criminal vehicular operation after her attorney, Jeffrey Ring, argued that police should have at least tried to obtain a search warrant before her blood was taken to test its alcohol content.
The case is now in the hands of the Minnesota Supreme Court, which has been asked to weigh the potential of evidence disappearing as the suspect's body metabolizes alcohol against the suspect's Fourth Amendment guarantee against unreasonable search and seizure.
Assistant County Attorney Debra Schmidt argued before the high court Wednesday that for 42 years law enforcement has been using a protocol set by a U.S. Supreme Court decision.
Law enforcers have interpreted that to mean that when probable cause of a crime exists, the presence of alcohol is enough to allow for a warrantless blood draw.
The ruling, for now, would affect criminal vehicular operation or homicide cases, which involve injury or death, but could at some point affect other less-serious drunken driving offenses. Under Minnesota law, the proof of drunken driving is blood-alcohol content measured within two hours of the offense.
Prosecutors and law enforcement officials said that if the Supreme Court affirms the earlier rulings by the district and Appeals Court, it will create more chaos and confusion at accident scenes.
"What the Appeals Court decision does is ask police officers under very stressful circumstances with very competing demands to make split-second decisions on essentially constitutional issues," said Ramsey County Attorney Susan Gaertner. "That's not reasonable. We're talking about situations where an accident has occurred, often a serious one, with mangled cars, bleeding bodies, possibly fatalities. And evidence of drinking. That's not the kind of circumstances where you want a police officer worrying about delaying what he needs to do by getting a warrant."
