A divided Supreme Court on Wednesday struck down a Missouri law that allowed
police routinely to force drunk-driving suspects to give blood samples without
a warrant and without consent.
A 5-4 majority agreed that the inevitable dissipation of alcohol from a
suspect's blood could not be regarded per se as an exigency that would justify
a blood draw without a warrant under the Fourth Amendment.
Over the years, the court has endorsed exceptions to the warrant requirement of
the Fourth Amendment, including when destruction of evidence is imminent and
police cannot wait for a warrant. The issue before the court was whether the
natural dissipation of alcohol in blood was the kind of phenomenon that always
justified proceeding without a warrant.
Justice Sonia Sotomayor, writing for the majority, said no. But she cautioned
that exigent circumstances still "may arise" that would allow drawing
blood without a warrant, case by case. The court said that with advances in
technology and procedures that allow police to obtain warrants quickly, police
are not usually hampered by the need for warrants as they combat drunk driving.
Most states, she said, now allow prosecutors to obtain warrants by phone, email
or teleconferencing.
Chief Justice John Roberts Jr., writing for himself and Justices Samuel Alito
and Stephen Breyer in a partial concurrence and dissent, chastised the majority
for failing to give clear guidance on what the new rule is. "A police
officer reading this Court's opinion would have no idea – no idea – what the
Fourth Amendment requires of him, once he decides to obtain a blood sample from
a drunk driving suspect who has refused a breathalyzer." These justices
did agree, however, that warrants should be sought when possible.
In a separate concurrence, Justice Anthony Kennedy expressed the hope that
"in due course may find it appropriate and necessary consider a case
permitting it to provide more guidance than it undertakes to give
today."
Justice Clarence Thomas was the only court member who said that a per se
exigency rule was appropriate, because the natural dissipation of alcohol in
the blood in effect results in "rapid destruction of evidence."
Thomas wrote, "Even a slight delay may significantly affect probative value
in borderline cases of suspects who are moderately intoxicated."
The ruling was a victory for the American Civil Liberties Union and its
longtime legal director Stephen Shapiro, who argued for his first time at the
high court on behalf of defendant Tyler McNeely. "We know from experience
that drunk-driving laws can be strictly enforced without abandoning
constitutional rights," Shapiro said in a statement. "Today's
decision appropriately recognizes what half the states have already demonstrated
– that maintaining highway safety does not require sacrificing personal
privacy."
When a Missouri police officer stopped McNeely for speeding and weaving across
the road, he refused to take a breath test. The officer then took McNeely to a
hospital for a blood test. McNeely refused again, despite a warning that such a
refusal automatically resulted in revocation of his driver's license The blood
sample was taken anyway, revealing an elevated blood alcohol content level. At
trial, he sought to suppress the blood results on Fourth Amendment grounds. The
trial court agreed that the case did not present circumstances that would have
made it impossible to obtain a warrant. The Missouri Supreme Court agreed that
dissipation of blood alcohol was not, by itself, enough to justify a
warrantless search.
