Whether the compelled withdrawal of Schmerber's blood violated due process under the Fourteenth Amendment.
Holding
No. Under the circumstances, the blood draw did not offend due process.
Reasoning
The Court treated Breithaupt v. Abram as controlling on the due-process question. Breithaupt upheld the use of blood-test evidence where a physician drew blood from an unconscious accident victim in a hospital through medically accepted procedures.
Schmerber's express objection did not make the procedure so brutal or offensive that it violated the fundamental fairness protected by due process. The Court emphasized that the test was performed by a physician, in a hospital, in a simple and medically acceptable manner. It reserved different questions for police-initiated violence, unreasonable force, or disregard of a reasonable request for another form of testing.
