Summary

The court addressed the validity of a DWI blood warrant and the sufficiency of probable cause affidavits. The court held that a blood warrant affidavit must contain specific articulable facts establishing probable cause that the suspect was operating a motor vehicle while intoxicated — not merely conclusory statements.

The court further held that observations of bloodshot eyes, odor of alcohol, and failed field sobriety tests, taken together, are generally sufficient to establish probable cause for a blood draw warrant.

State v. Villarreal

475 S.W.3d 784 (Tex. Crim. App. 2014)

Good Law

The Texas Court of Criminal Appeals held that mandatory blood draws in DWI cases under the Texas Transportation Code's implied consent provisions violate the Fourth Amendment when conducted without a warrant. The court ruled that the implied consent statute does not create an exception to the warrant requirement and that the natural dissipation of alcohol in the bloodstream does not automatically create exigent circumstances justifying a warrantless blood draw.
