Tampa DUI Lawyer Reviews Supreme Court on Blood Draws and notes that today the Supreme Court holds that in DUI investigations the natural dissipation of alcohol in the bloodstream does not constitute an exigency to justify warrantless blood test. The Court affirmed the decision of the Supreme Court of Missouri, concluding that “the natural dissipation of alcohol in the bloodstream does not establish a per se exigency that suffices on its own to justify an exception to the warrant requirement for nonconsensual blood testing in drunk-driving investigations.”
In DUI / drunk-driving investigations, the natural dissipation of alcohol in the bloodstream does not constitute per se exigency sufficient to justify an exception to Fourth Amendment’s warrant requirement for nonconsensual blood testing. The principle that a warrantless search of the person is reasonable only if it falls within a recognized exception applies where the search involves a compelled physical intrusion beneath the person’s skin and into his veins to obtain a blood sample to use as evidence in a criminal investigation. Natural dissipation of alcohol in the blood may support an exigency finding in a specific case, but it does not do so categorically. Whether a warrantless blood test of a drunk-driving suspect is reasonable must be determined case by case based on the totality of the circumstances.
