Supreme Court Rules that Traffic Stop Was Lawful, Despite Police Officer’s Misunderstanding of Traffic Law
The U.S. Supreme Court issued a ruling in December 2014 that could have a significant effect on DWI cases in New Jersey. The case involves two fundamental principles of the American criminal justice system. First, law enforcement officers must have reasonable suspicion of a criminal or traffic offense in order to make a traffic stop. Second, it is not a defense to prosecution for a person to claim that he or she did not know something was illegal. What happens, however, when a police officer makes a mistake of law? In Heien v. North Carolina, a defendant argued that a traffic stop that resulted in drug charges was unreasonable because the officer incorrectly thought having only one working brake light was a traffic violation. The court held that the officer did not violate the defendant’s rights, despite not knowing the law, since the mistake was “reasonable.”
An officer pulled the defendant’s vehicle over in April 29, 2009 at about 8:00 a.m. He testified that he saw the vehicle pass on the highway and thought the driver looked “very stiff and nervous.” After following the vehicle for several miles, he noticed that it had only one working brake light. He pulled the vehicle over, believing this to be a traffic violation. The defendant, who owned the vehicle, consented to a search, and the officer found drugs.
The defendant pleaded guilty to drug charges after the trial court denied his motion to suppress the results of the search, reserving the right to appeal. A state appellate court reversed the conviction, finding that the traffic stop was unreasonable because the driver had not broken any traffic laws. The North Carolina Supreme Court reversed that ruling, and the U.S. Supreme Court affirmed the conviction. Continue reading
