Refusal to Identify During a Lawful Detention
RC Phillips
DDA Ret.
November, 2014
Question: Is it a crime in California for a person to refuse to identify himself to a peace officer during a lawful detention? My opinion is that depending upon the circumstances, refusing to identify oneself during a lawful detention may be a violation of P.C. § 148(a)(1) for “delaying or obstructing” an officer in the performance of his (or her) duties.

(Hiibel v. Sixth Judicial District Court of Nevada (2004) 542 U.S. 177.) California, however, has no such statute. But it is my argument that law enforcement’s right to temporarily detain a criminal suspect on less than probable cause (i.e., a “reasonable suspicion”) for the purpose of determining whether that person was, is, or is about to be involved in criminal activity—a power afforded by case law only (Terry v. Ohio (1968) 391 U.S. 1)—inherently includes the concurrent power to require that person to identify himself despite the lack of a statute so stating. Indeed, the United States Supreme Court has specifically held that: “[T]he ability to briefly stop [a suspect], ask questions, or check identification in the absence of probable cause promotes the strong government .... © 2026 Legal Updates, LLC.
