We granted en banc review of this case to consider whether to overrule our decision in
United States v. Harvey,
Having considered the question anew, we conclude that the Fourth Amendment does not require the arrest of a suspect in order for law enforcement officers to cause the taking of a sample of the suspect’s blood without consent or a warrant. We therefore overrule Harvey. We vacate the panel’s decision and remand the case to the panel for a determination whether probable cause existed to support the taking of Chapel’s blood.
BACKGROUND
We adopt the statement of facts set forth by the panel,
Daniel Chapel was severely injured in a single-vehicle motorcycle accident in a remote part of Glacier National Park. Several park rangers and a park medic came to his assistance. The rangers administered first aid and the medic radioed a helicopter to evacuate Chapel to the regional hospital. The medic also prepared an I.V. as a routine life-support measure.
While administering first aid, the rangers noticed telltale signs that Chapel had been drinking: his breath smelled of alcohol, his speech was slurred, his eyes were bloodshot. The rangers sought to gather hard evidence of Chapel’s intoxication. They first asked Chapel to take a breathal-izer test, but he refused. Knowing that Chapel’s blood alcohol content (“BAC”) would dissipate, the rangers instructed the medic to obtain a blood sample for later testing. The medic, who had already inserted a sterile needle into Chapel’s arm to administer the I.V., withdrew a small sample of Chapel’s blood.
*1418 The rangers’ suspicions turned out to be only too well founded. The Montana Forensic Science Lab examined Chapel’s blood sample and determined that he had a BAC of 0.21 grams of alcohol per 100 milliliters of blood; in other words, he was crapulent. Based largely on this evidence, Chapel was convicted of drunk driving under 36 C.F.R. § 4.23(a)(2)
In considering Chapel’s appeal, the panel reviewed the circumstances under which the Fourth Amendment would permit the non-consensual seizure of blood, without a warrant, to test for alcohol content. The panel first recounted the three requirements derived from
Schmerber v. California,
First, an officer ordering that a blood sample be taken must reasonably believe he is “confronted with an emergency, in which the delay necessary to obtain a warrant, under the circumstances, threaten[s] ‘the destruction of evidence.’” Second, the officer must have probable cause to believe the suspect has been driving under the influence of alcohol. Third, the procedures used to extract the blood must be reasonable; that is, the sample must be taken by trained medical personnel in accordance with accepted practices.
Chapel,
The panel also recited a fourth requirement, subsequently imposed by
Harvey,
that “the officer must arrest the suspect before, or soon after, taking the sample.”
Id.
(citing
Harvey,
The panel observed that the officers had met the three requirements of
Schmerber,
but had failed to make an arrest as required by
Harvey.
The panel thus concluded that “[although the rangers’ conduct in seizing Chapel’s blood was entirely reasonable,” their failure to arrest Chapel rendered their seizure of his blood sample unconstitutional under
Harvey. Chapel,
DISCUSSION
The panel correctly recognized that the rule of Harvey, requiring that police formally arrest a suspect prior to ordering removal of a blood sample, controlled its decision in the present case. We now reexamine Harvey to determine whether its constitutional ruling retains vitality. We conclude that it does not.
We start with the proposition that courts and juries should not be denied probative evidence unless it was procured in violation of the rights of the accused. In the situation posed by this case as well as by
Harvey,
it is difficult to see what rights of the accused were violated by their not having been arrested at the time the blood was extracted. Why, then, did
Harvey
impose a requirement of arrest? The opinion in
Harvey
made clear that its ruling was based on its interpretation of
Schmerber.
The central reason why
Schmerber
permitted the non-consensual taking of blood without a warrant, according to
Harvey,
was that the taking was part of a search incident to arrest.
Harvey,
We now know from the Supreme Court’s reasoning in a case decided after
Harvey
that the seizure of blood in
Schmerber
“fell within the exigent-circumstances exception to the warrant requirement.”
Winston v. Lee,
The result we reach today does no violence to the Fourth Amendment or the protections it affords to those suspected of crime. Before a law enforcement officer may lawfully take a blood sample without consent or a warrant, he or she must have probable cause to believe that the suspect has committed an offense of which the current state of one’s blood will constitute evidence.
Schmerber,
In addition to probable cause, the other
Schmerber
requirements remain in place. The officer must still reasonably believe that an
emergency
exists in which the delay necessary to obtain a warrant would threaten the loss or destruction of evidence. The procedures used to extract the sample must still be reasonable and in accordance with accepted medical practices.
See Schmerber,
There is one subsidiary point to be addressed. Chapel contends that the taking of his blood without an arrest violated the federal “implied consent” statute, 18 U.S.C. § 3118. Section 3118 provides, in pertinent part:
(a) Consent. — -Whoever operates a motor vehicle in the ... territorial jurisdiction of the United States consents thereby to a chemical test ... of such person’s blood, breath, or urine, if arrested for any offense arising from such person’s driving under the influence of a drug or alcohol....
(b) Effect of refusal. — Whoever, having consented to tests ... by reason of subsection (a), refuses to submit to such a test ..., after having first been advised of the consequences of such a refusal, shall be denied the privilege of operating a motor vehicle [within the] territorial jurisdiction of the United States [for] the period of a year ..., and such refusal may be admitted into evidence....
(Emphasis added).
The short answer to Chapel’s contention is that section 3118, by its own terms, applies to the suspect only “if arrested.” Chapel was not arrested, and the statute was not triggered.
Chapel argues, however, that the statute is meaningless if it is not construed to imply the requirement of an arrest prior to a test for which there is no express consent. We do not think so. Although it is true that Schmerber, as we now construe it, obviates the necessity of an implied consent both before and after arrest, this fact does not deprive the statute of meaning or effect. The two subsections must be read together. Subsection (a) implies a consent to testing in the event of an arrest, and subsection (b) provides that drivers who have so consented and refused a test, after having been advised of the consequences, may lose their driving privileges and may have the refusal used *1420 against them in court. Officers may decide to test without an arrest, under Schmerber, or, if they prefer not to cause the forcible extraction of a sample, may make an arrest and rely on the alternative sanctions subsection (b) provides. The statute has not become useless or nonsensical. There is accordingly no occasion for us to consider whether heroic measures of construction are necessary or appropriate to save the statute. As written, section 3118 applies “if’ the suspect is arrested, and there we leave it. 4
We therefore conclude that no statutory bar stands in the way of our decision. We accordingly overrule Harvey, and hold that an arrest is not a constitutional prerequisite for the non-consensual taking of Chapel’s blood without a warrant. We vacate the panel’s decision, and remand to the panel for a determination whether probable cause existed to support the taking of blood from Chapel, and for further disposition consistent with this opinion.
VACATED and REMANDED.
Notes
.
Harvey
noted an exception to the arrest requirement if the suspect was "unconscious or otherwise so incapacitated as to be unable to appreciate the significance of an arrest.”
Harvey,
. The Sixth Circuit reached a similar conclusion in
United States v. Berry,
. A case meeting the three
Schmerber
requirements necessarily falls within the exigent circumstances exception to the Fourth Amendment; establishment of exigent circumstances is the first
Schmerber
requirement.
See Schmerber,
. Our disposition of this question makes it unnecessary for us to decide whether evidence obtained in violation of section 3118 is inadmissible.
