DUI Arrests and Blood Tests

When law enforcement stops a California driver for allegedly driving under the influence (DUI), the officer has the option of making the driver submit to either a blood test or a breath test.  California Vehicle Code Section 23612 (a), regarding blood tests for DUI, is based on the belief that by using public roadways, a driver that is legally detained for a suspected DUI gives IMPLIED consent to a blood or breath test.  The California DMV  can also issue fines and suspend someone’s license for a year if they refuse consent.

BUT exceptions to that law exist. 

The U.S. Supreme Court decided the case that detailed one of the first exceptions to DUI law nearly 40 years ago.  In Schmerber vs. California, the Court found that the extreme police brutality by the officers that arrested and obtained the defendant’s blood made the blood draw illegal.  California DUI case law has usually said that unless the case shows extreme circumstances, like those described  in Schmerber, the blood must be taken in a “medically reasonable” manner.

In April of this year, the U.S. Supreme Court sided with a driver who refused a blood test in McNeely vs.Missouri. In that matter, the Court said officers could only do a forced blood draw on a driver for a felony DUI. 

A driver accused of a misdemeanor DUI does not have to submit to a blood test unless the officer either obtains a search warrant or “exigent circumstances” exist in the situation. “Exigent circumstances” are urgent or emergency circumstances that would make it impossible for the officers to obtain a warrant, because evidence of the crime would be gone by the time the warrant is issued. 

Otherwise, the Court held, forcing a driver to submit to a blood draw in a misdemeanor case will result in a violation of the person's rights against unreasonable search and seizure under the Fourth Amendment of the U.S. Constitution and (in California) Article 1, Section 13 of the California Constitution.

Since alcohol slowly dissipates and is metabolized in the body over the passage of time, the McNeely decision went beyond the current practices of police in arresting someone for DUI and obtaining a blood or breath sample with or without their permission or consent.

In July 2013, the California Supreme Court decided a related issue.  The Court decided People v. Cuevas, which looked at 7 separate cases from Alameda County where officers obtained blood samples from drivers after DUI arrests.  The issue in Cuevas was whether the blood was taken in a “medically reasonable manner,” as defined by Schmerber.  Some of the blood tests done after the defendants were arrested were not taken in a hospital and officers were not aware of the qualifications of the persons who took blood from the defendants.  The Cuevas court did not mention the McNeely decision, but decided that under Schmerber, the blood tests were performed in a medically reasonable fashion. The arrested drivers did not complain of pain, the needles appeared to come from apparently sterile packaging, etc.

Most people arrested for a first-time DUI are generally law-abiding citizens, and they don’t understand the procedures involved.  In fact, the person arrested often asks the officer whether the officer thinks they should take a blood test or a breath test!  In close cases, the officers seem to encourage blood tests when asked, because blood is believed to be more reliable. 

HOWEVER, a local Santa Clara County lawyer recently checked into whether the preservative used in the blood vials to retain the alcohol content was expired.  He found that the preservative used in several blood draws was indeed expired.  Unfortunately, the California courts have not published any cases resulting from that issue.

The lesson from these incidents is clear:  When you agree to a blood test - especially if an officer has you take a blood test against your will – consult an attorney as soon as possible.  It does not matter whether the results of the DUI blood or breath test are over the legal limit.  A lawyer can arrange to have a professional retest your blood sample, check the levels and expiration dates of preservatives used, and, in a case when the police used force, the McNeely decision may affect your DUI case differently than it would have before that date.
