An Officer’s Reasonable Mistake of Law and Recent Court of Appeals Ruling

The United States Supreme Court in 2014 ruled in Heien v. North Carolina, 135 S. Ct. 530 (affirming State v. Heien, 366 N.C. 271 (2012)), that an officer’s objectively reasonable mistake of law in making a stop or arrest is reasonable under the Fourth Amendment.

The defendant in Hopper was driving on Piedmont Circle, a loop road in an apartment complex in Winston-Salem. It was raining heavily. An officer noticed … Read more
