The US Supreme Court reviewed three cases: Birchfield (North Dakota), Beylund (North Dakota) and Bernard (Minnesota). In each case, the driver was arrested for DUI in a state which had a law requiring a driver suspected of DUI to undergo blood alcohol testing. Refusal to submit to testing in those states resulted in criminal punishment.
The Court held that blood tests are more intrusive than breath tests. Not only is the test physically intrusive and painful, the blood sample obtained contains far more information than just the blood alcohol content. The Intrusiveness of that test raises the issue of whether the requirement to undergo such test is “unreasonable” under the 4th amendment. Even when the state has “implied consent” laws requiring that any licensed driver be deemed to have consented to a blood alcohol test if he is arrested for suspicion of DUI, the Court held that “motorists cannot be deemed to have consented to submit to a blood test on pain of committing a criminal offense.”
It is yet unknown how Birchfield will impact California law since there is no separate California criminal offense for the refusal of a blood alcohol test. Refusals may enhance sentencing and there are certainly consequences for refusal in the form of administrative DMV action against the driver’s license, but no separate criminal charge for refusal. The more interesting situation arises in California arrests where the officer suspects the driver of being under the influence of drugs, removing the option of a breath test. Will officers suspecting DUI of drugs be required to obtain a warrant prior to a blood draw? This remains to be seen as the California courts apply the principals of Birchfield under California law. This case includes a fascinating history of both DUI law and the 4th Amendment right to remain free of unreasonable search and seizure. It is worth a read.
