Can police rely on database warrants for lawful arrests in Utah? State v. Pola Explained

In State v. Pola, the Utah Court of Appeals addressed important questions about what constitutes a lawful arrest and whether police may rely on database information when making arrests based on outstanding warrants.

Background and Facts

Kenneth Pola was sitting outside an abandoned restaurant when a sergeant approached him about possible trespassing. After running Pola’s name through a police database, the sergeant discovered multiple outstanding warrants for assault, trespassing, and disorderly conduct. During the arrest, Pola became agitated and spat on both the sergeant and a backup officer. Pola was subsequently charged with two counts of propelling a substance at a peace officer under Utah Code section 76-5-102.6.

Key Legal Issues

Pola argued on appeal that the jury instructions were defective because they failed to define “lawful arrest” and “probable cause,” and incorrectly suggested that no mens rea applied to the “prisoner” element of the offense. He also contended there was insufficient evidence that he was lawfully arrested, claiming the warrants were invalid.

Court’s Analysis and Holding

The court applied plain error review since Pola failed to preserve his objections below. Under this standard, Pola had to demonstrate not only error, but also prejudice—that there was a reasonable probability the outcome would have been different with proper instructions. The court found no prejudice, explaining that police databases constitute “reasonably trustworthy information” for probable cause determinations. The officers had valid grounds to arrest Pola based on the database showing outstanding warrants, and nothing in the record definitively established the warrants were invalid.

Practice Implications

This decision reinforces that law enforcement may rely on police databases when making arrests, even if defendants later claim warrants are invalid. For defense counsel, the case highlights the importance of preserving jury instruction objections at trial rather than relying on plain error review, which requires showing actual prejudice. The court’s analysis also demonstrates that challenges to the validity of arrest warrants must be supported by concrete evidence rather than mere assertions.
