Can Utah's single criminal episode statute bar subsequent felony prosecution? State v. Sommerville Explained

Background and Facts

In State v. Sommerville, the defendant was arrested for DUI and multiple traffic offenses arising from a hit-and-run accident in December 2006. Sommerville was issued citations for following too closely, failure to remain at the scene, operating without insurance, and driving on a suspended license. He paid a fine for the following too closely citation, which constituted a conviction. Murray City then moved to dismiss the remaining misdemeanor charges under Utah’s Single Criminal Episode Statute, arguing they arose from the same criminal episode. The justice court dismissed these charges, including the misdemeanor DUI.

Salt Lake County subsequently charged Sommerville with felony DUI in district court based on his prior DUI convictions, along with the other misdemeanor offenses that had been dismissed. The district court dismissed the misdemeanors but denied Sommerville’s motion to dismiss the felony DUI charge.

Key Legal Issues

The central issue was whether Utah’s Single Criminal Episode Statute (Utah Code sections 76-1-402 and -403) barred subsequent prosecution of the felony DUI offense. The statute requires four criteria: (1) offenses from the same criminal episode, (2) prior conviction or other specified termination, (3) offenses within jurisdiction of a single court, and (4) offenses known to the prosecuting attorney at arraignment.

Court’s Analysis and Holding

The Utah Court of Appeals reversed, finding all four criteria satisfied. The court accepted that the offenses arose from the same criminal episode based on the City’s concession. Sommerville’s payment of the fine constituted a conviction under the statute. Critically, the court concluded that both the misdemeanor and felony DUI were within the jurisdiction of a single court—the district court—because district courts have jurisdiction over class B and C misdemeanors when included in an information alleging a felony from the same criminal episode. The State failed to argue that the felony DUI was unknown to prosecutors.

Practice Implications

This decision significantly impacts prosecution strategy for cases involving multiple offenses from a single criminal episode. The court rejected the district court’s reasoning that limited justice court jurisdiction could prevent application of the Single Criminal Episode Statute. Prosecutors must carefully consider whether any offense might later be charged as a felony and should generally file all related charges in district court initially to maintain control over the prosecution and avoid statutory bars on subsequent proceedings.
