Background
An Oregon state trooper stopped Donna Chrystene Butler on a rural road at night and arrested her for driving under the influence of intoxicants after administering field sobriety tests. Butler declined to provide a breath sample. She told the trooper that she had last consumed alcohol with dinner approximately five hours earlier, and the trooper estimated that her blood-alcohol level was probably near 0.08 percent.
Believing that Butler’s blood-alcohol evidence would dissipate during the approximately three hours required to obtain a warrant in Wallowa County, the trooper transported her to a hospital for a warrantless blood draw. The trial court found that the trooper had an objectively reasonable basis to believe exigent circumstances existed, denied Butler’s suppression motion, and a jury convicted her of DUII. Butler appealed, arguing that the blood draw violated Article I, section 9, of the Oregon Constitution and the Fourth Amendment.
The Court’s Holding
The Oregon Court of Appeals affirmed. Under controlling Oregon Supreme Court precedent, the evanescent nature of blood-alcohol evidence ordinarily creates an exigency when an officer can obtain a blood sample faster than a warrant. Although Butler argued that electronic-warrant technology and subsequent Oregon case law had undermined that precedent, the court explained that it remained bound by the Oregon Supreme Court’s decision in State v. Machuca. The record supported the finding that the trooper could obtain Butler’s blood sample faster than he could secure a warrant.
The blood draw also satisfied the Fourth Amendment’s case-specific, totality-of-the-circumstances test. The trial court credited testimony that even a telephone-assisted warrant would have taken about three hours, no other troopers were available to help with the investigation or warrant application, and the trooper reasonably feared that Butler’s comparatively low suspected blood-alcohol level would fall during the delay. Those circumstances established an exigency despite the absence of a crash scene requiring police attention.
Key Takeaways
- Under binding Oregon precedent, a warrantless blood draw is permissible when an officer can obtain the sample faster than a warrant and delay threatens the loss of blood-alcohol evidence.
- For Fourth Amendment purposes, courts must evaluate exigency case by case, considering warrant procedures, expected delay, available technology, investigative demands, and practical resource constraints.
- A roughly three-hour warrant process, scarce nighttime law-enforcement resources, and the anticipated dissipation of a near-limit blood-alcohol level supported exigent circumstances here.
Why It Matters
The decision illustrates that the availability of electronic or telephonic warrants does not automatically defeat an exigency claim. Concrete evidence about local warrant-processing time, staffing constraints, and the likely loss of evidence can still justify a warrantless blood draw under both the Oregon and federal constitutions.
The opinion is a nonprecedential memorandum opinion under ORAP 10.30 and may be cited only as that rule permits.
