Can intervening crimes justify an arrest after initial police misconduct? State v. Griego Explained

In State v. Griego, the Utah Court of Appeals addressed a critical question about the relationship between police misconduct and subsequent criminal liability. The case demonstrates how intervening criminal acts can provide independent justification for arrest, even when officers’ initial conduct was potentially unlawful.

Background and Facts

Officers responded to a domestic violence report and eventually entered Griego’s home without a warrant to investigate. Although the warrantless entry may have been illegal, Griego’s response escalated the situation dramatically. He became verbally abusive, physically resisted the officers, kicked them multiple times, and created a public disturbance that drew neighbors’ attention. The State charged him with assault by a prisoner and interference with an arresting officer.

Key Legal Issues

Griego moved to dismiss the charges, arguing that because his initial seizure was illegal, he was not under “lawful arrest” as required by the assault by a prisoner statute, and that the officers had not given him any “lawful order” as required by the interference statute. The central issue was whether an initially unlawful police action could be cured by the defendant’s subsequent criminal conduct.

Court’s Analysis and Holding

Following State v. Gardiner, the court held that “an illegal entry or prior illegality by officers does not affect the subsequent arrest of a defendant where there is an intervening illegal act by the suspect.” The court found that Griego’s conduct after the initial seizure—including fighting with officers and yelling obscenities in public—constituted disorderly conduct, an independent crime that justified his arrest. Once lawfully arrested for disorderly conduct, his subsequent assaults on officers properly supported the assault by a prisoner charges.

Practice Implications

This decision establishes important boundaries for challenging arrests based on initial police misconduct. Defense attorneys should carefully analyze whether their clients committed independent crimes after any alleged illegality, as such intervening acts can provide separate justification for arrest and prosecution. The court emphasized that allowing defendants immunity for new crimes would give them “an intolerable carte blanch to commit further criminal acts” connected to police misconduct.
