May a law enforcement officer who personally investigates, but does not observe, a vehicle crash testify as to his opinion about who was driving the vehicle? Does the answer depend upon whether the officer is qualified as an expert in accident reconstruction? The court of appeals considered those questions in State v. Denton, ___ N.C. App. ___ (June 4, 2019), decided yesterday.

To Prove Aggravating Factors for DWI in Superior Court, State Must Provide Notice
One person convicted of misdemeanor impaired driving may be placed on probation and ordered to complete 24 hours of community service. Another may receive an active sentence of three years’ imprisonment. The severity of the sentence depends largely on the presence of aggravating factors, which must be proved by the State.
When a misdemeanor impaired driving conviction entered in district court is appealed for trial de novo in superior court, the State must notify the defendant no later than ten days before trial that it intends to prove one or more aggravating factors. G.S. 20-179(a1)(1). If the State fails to provide that notice, the factors may not be used by the superior court to determine the defendant’s sentence. The court of appeals recently affirmed in State v. Hughes, ___ N.C. App. ___ (April 16, 2019), that there is no exception to this rule for aggravating factors that were found by the district court below.

Studies Tout Safety Benefits of Expanded Ignition Interlock
The National Center for State Courts recently published an Ignition Interlock Report reviewing the latest research on ignition interlock programs. Two of the studies cited reported efficacy rates striking enough to attract the attention of any policy wonk interested in highway safety.

State v. Shelton Refines Sufficiency Analysis in Drugged Driving Case
The court of appeals decided State v. Shelton, ___ N.C. App. ___ (2019) yesterday, determining that the evidence of the defendant’s impairment was sufficient when he took impairing drugs hours before crashing his vehicle into a pedestrian after his brakes failed. Two aspects of the case are of particular interest: (1) the court’s evaluation of the sufficiency of the evidence in a case where no one opined that the defendant was impaired; and (2) how the State obtained evidence that drugs remained in the defendant’s system in the first place.

U.S. Supreme Court Grants Review on Issue of Implied Consent
The United States Supreme Court granted certiorari a few weeks ago to consider whether a state statute authorizing the withdrawal of blood from an unconscious driver suspected of impaired driving provides an exception to the Fourth Amendment warrant requirement. The case, Mitchell v. Wisconsin, arose in Wisconsin, but the issue may sound familiar to practitioners in North Carolina. Our state supreme court held in State v. Romano, 369 N.C. 678 (2017) (discussed here) that the warrantless withdrawal of blood from an unconscious DWI suspect pursuant to state statute when there was no exigency violated the Fourth Amendment. The Supreme Court of Wisconsin reached a different conclusion in Mitchell. The case provides the United States Supreme Court with an opportunity to tie up the ends it left loose in Birchfield v. North Dakota, ___ U.S. ___, 136 S. Ct. 2160 (2016) by clarifying how implied consent laws authorizing blood draws without a suspect’s consent do or do not comport with the Fourth Amendment.

What Happens When the Jury Is Instructed on the Wrong Theory?
Suppose the trial court, over the defendant’s objection, instructs the jury on a theory of a crime that is not supported by the evidence. Is the defendant entitled to automatic reversal on appeal? Or, alternatively, must the appellate court evaluate whether the erroneous instruction prejudiced the defendant? The North Carolina Supreme Court answered these questions in State v. Malachi, ___ N.C. ___ (2018), published last Friday, and applied its answer in State v. Fowler, ___ N.C. ___ (2018), decided the same day.

The License Revocation that Immediately Follows Arrest for DWI
I spent much of the afternoon teaching magistrates, and one of the topics we covered was the immediate license revocation that often is ordered upon a person’s arrest for impaired driving.

Got Probable Cause for Impaired Driving?
Two recent North Carolina Court of Appeals opinions help delineate when an officer has probable cause to believe a driver is driving while impaired. In each case, the court of appeals reversed the trial court’s determination that the officer lacked probable cause.

State v. Eldred: Court of Appeals Evaluates Sufficiency of Circumstantial Evidence of DWI
Consider whether the following facts are sufficient to support a conviction for DWI:
The scene. Law enforcement officers in Avery County respond to a reported accident on the highway leading to Grandfather Mountain around 8:30 p.m. They find a Jeep Cherokee on the side of the highway, with a damaged side panel. Tire impressions indicate that the vehicle traveled about 100 feet after leaving the roadway. A large rock embankment along the roadway is scuffed. No one is in the car, which is registered to Paul Eldred.
The defendant. A law enforcement officer finds Eldred walking along the side of the highway two or three miles north of the accident. Eldred has a mark on his forehead, is twitching, and is unsteady on his feet. The officer asks Eldred why he is walking on the highway. Eldred responds: “I don’t know, I’m too smoked up on meth.” The officer calls for medical help, and Eldred is taken to the hospital.
The interview. Another officer questions Eldred at the hospital around 10 p.m. Eldred explains that he was driving his car when it ran out of gas. He then says “‘he was hurt bad and was involved in a wreck a couple of hours ago.’” Eldred tells the officer that he had not been drinking alcohol. The officer asks whether Eldred has taken any medications, and Eldred says he is “on meth.” During the interview, Eldred is twitching, appears dazed and has difficulty answering questions. He does not know the date, the day of the week, or the time.

Rules for Breath Tests in DWI Cases
The easiest way for the State to prove impairment in a prosecution for impaired driving is by introducing the results of a test of the defendant’s breath. Such test results are admissible without the foundation that would otherwise be required for this kind of scientific evidence so long as the testing was carried out in accordance with statutory and administrative rules governing implied consent testing. G.S. 20-139.1(b). Because the rule allowing breath test results to be introduced into evidence is relied upon so often, I thought it might be helpful to review the admissibility rule and the requirements for such tests.
