Do DWI Suspects Have a Right to the Least Intrusive Chemical Test?

In its seminal opinion establishing the State’s right to withdraw blood from a DWI suspect over his objection and without a warrant when there are exigent circumstances, the United States Supreme Court left a significant question unanswered. The court in Schmerber v. California, 384 U.S. 747 (1966), noted that the petitioner “is not one of the few who on grounds of fear, concern for health, or religious scruple might prefer some other means of testing, such as the ‘Breathalyzer’ test petitioner refused. . . . We need not decide whether such wishes would have to be respected.” Id. at 771.

So how have courts in the ensuing four decades answered this question? Must an impaired driving suspect be offered the least intrusive type of chemical test available or a choice about the type of testing when he or she has a sincere objection to a particular test?

Court of Appeals Upholds Admissibility of Social Media Evidence Based on Circumstantial Evidence of Authenticity

The court of appeals recently decided State v. Ford, a case about the authentication of social media evidence. This is the first North Carolina appellate case to give careful consideration to the issue, and the opinion sets a relatively low bar for authentication. Because this type of evidence is increasingly prevalent, the case is an important one.

State v. Osteen:  Court of Appeals Approves Admission of Lay and Expert Opinion Testimony Regarding Drug Impairment

Proving that a driver was impaired by alcohol is not all that difficult, particularly when the driver submits to a breath test and the result is .08 or more.  Proving that a driver was impaired by drugs or by a combination of alcohol and drugs is considerably more challenging. But an opinion released yesterday by the court of appeals demonstrates one way in which it can be done, even without a confirmatory chemical test.

Field Sobriety Testing and the Fifth Amendment

Most drivers stopped on suspicion of impaired driving are asked to submit to field sobriety tests before they are arrested.  Those tests often include the three standardized tests, which researchers have found to enhance officers’ ability to accurately identify impairment:  the one-leg stand, the walk-and-turn, and the horizontal gaze nystagmus tests. Officers sometimes use other types of field tests that have not been validated, such as asking participants to recite the alphabet or to conduct counting exercises. Evidence gained from any of these pre-arrest tests may be admitted against the defendant at trial without running afoul of the Fifth Amendment right to be free from self-incrimination.  That’s because suspects aren’t in custody for purposes of the Fifth Amendment or Miranda v. Arizona, 384 U.S. 436 (1966) when they are temporarily detained for a traffic stop and are asked a moderate number of stop-related questions. Berkemer v. McCarty, 468 U.S. 420, 440 (1984); State v. Braswell, 222 N.C. App. 176 (2012). But what if the suspect is asked to perform field sobriety tests after he is arrested?  Must he first be provided Miranda warnings?

What’s NOT a Public Vehicular Area?

After the legislature broadened the definition of “public vehicular area” in 2006 to include areas “used by the public for vehicular traffic at any time,” many wondered whether there was any place where one could drive a vehicle (other than a private driveway) that wasn’t considered a public vehicular area. There was even some doubt about those private driveways, since members of the public can drive into them and sometimes do so even without an invitation from the resident. Moreover, North Carolina’s appellate courts had broadly interpreted the term for years—even when it was more narrowly defined.  But the court of appeals put the brakes on an overly expansive reading of public vehicular area last year, rejecting, in State v. Ricks, ___ N.C. App. ___, 764 S.E.2d 692 (2014), the State’s argument that all property used by the public for vehicular traffic is, in fact, a public vehicular area.

The Eighth Circuit Considers Implied Consent, but I Still Haven’t Found What I’m Looking For

I admit that I may have a problem. I am dedicated to (perhaps obsessed with) the pursuit of a legal theory that satisfactorily squares the doctrine of implied consent with the Fourth Amendment. A thousand Westlaw searches later, I have yet to find analysis such an analysis by a court. So I was a little surprised when the United States Court of Appeals for the Eighth Circuit explained earlier this summer that the Supreme Court determined more than thirty years ago in South Dakota v. Neville, 459 U.S. 553 (1983), that implied consent testing carried out under threat of license revocation comported with the Fourth Amendment. Did I miss something?

Daubert Doesn’t Look Much Different from Howerton When it Comes to Retrograde Extrapolation

The court of appeals gave the green light last week for law enforcement officers to continue to testify as scientific experts in DWI cases involving retrograde extrapolation–notwithstanding the legislature’s amendment of Rule 702 to adopt the Daubert standard. The court held in State v. Turbyfill that a field technician for the Forensic Test for Alcohol Branch of DHHS (FTA), who was trained as a law enforcement officer and chemical analyst (which authorized him to conduct implied consent testing on breath testing instruments), was properly allowed to testify about a retrograde extrapolation calculation he performed using an FTA form. The technician’s inability to explain whether the rate he used to make the calculation was an “average,” a “mid-point,” or a “conservative” rate—he used all three terms to describe it—did not disqualify him as an expert since he “provided the trial court with a list of some thirty-nine articles . . . regarding blood alcohol research,” and “with North Carolina cases in which this Court upheld the use of retrograde extrapolation to establish blood alcohol content.”

Fourth Circuit: Cell Site Location Information Requires a Search Warrant

The Fourth Circuit just decided United States v. Graham, an important case about law enforcement access to cell site location information (CSLI). This post summarizes the case, explains its importance for North Carolina proceedings, and puts it in context in the broader debate about this type of information.

NC Court of Appeals Holds that DMV Records Are Non-Testimonial

In my 23-year career as a lawyer no case has had more impact on the criminal justice system than the U.S. Supreme Court’s decision in Crawford v. Washington. That case radically revamped the analysis that applies for confrontation clause issues, holding that “testimonial” statements by people who don’t testify at trial are not admissible unless the prosecution establishes both unavailability and a prior opportunity to cross-examine. More than 10 year after Crawford, courts are still struggling with the meaning of the key term “testimonial.” In one recent case the Court of Appeals had to decide whether DMV records are testimonial under the new Crawford analysis.
