SCOTUS Weighs in on Forced Blood Draws in DUI Cases
In the wake of today’s decision by the U.S. Supreme Court in Missouri v. McNeely, DUI defense attorneys across the land are doing the “happy dance.” Prosecutors (both state and federal) on the other hand are rending their garments and hair trying to figure out how to deal with the high court’s ruling that forced blood draws in most DUI cases will now require warrants, and the flood of “refusals” sure to follow as the implications of the case filter out to the public.
Wisconsin’s approach, first established in 1993 in State v. Bohling and then reinforced in 2004 in State v. Faust had been to allow warrantless blood draws in drunk driving cases after several criteria were met, including the presence of probable cause for the officer to believe the driver under investigation had indeed been driving under the influence of alcohol. The key factor that drove the Wisconsin interpretation was the fact that the blood alcohol level of a drunk driving suspect is continually shifting and dissipating from the time the driver is apprehended, and the extra time it takes to procure a warrant incontrovertibly causes BAC evidence to be lost.
Wisconsin’s rationale had recently served as a kind of dividing line in the national debate about warrantless blood draws.
