New York residents may be interested to hear that the Supreme Court ruled that DUI blood tests administered without a warrant may not be considered in court rulings. Furthermore, it decreed that police usually must attempt to obtain a search warrant from a judge before ordering blood tests for suspects of drunk driving. The verdict stemmed from the case of a Missouri man who was subjected to a blood test without a warrant. The man was arrested in Cape Girardeau County, Missouri, on a charge of drunk driving after a state trooper stopped his car for swerving and speeding. The man had two previous drunk driving convictions and refused to submit to a blood alcohol test. He failed numerous field sobriety tests, and the arresting officer said that his words were slurred and that he was very unsteady on his feet.
