Summary

West Jordan police investigated a domestic incident involving Peterson, a Salt Lake County Sheriff’s Deputy, but the West Jordan City Prosecutor declined to prosecute due to conflicts of interest. The Salt Lake City Prosecutor’s Office accepted the case and filed charges in Salt Lake City. Peterson moved to dismiss, arguing the Salt Lake City Prosecutor lacked authority to prosecute charges for incidents occurring outside Salt Lake City limits.

Analysis

The Utah Supreme Court’s decision in Salt Lake City v. Peterson clarifies the geographical limitations on city attorney prosecutorial authority and demonstrates that conflict-of-interest situations do not expand statutory jurisdiction.

Background and Facts

West Jordan police investigated a domestic incident involving Cory Peterson, a Salt Lake County Sheriff’s Deputy. The West Jordan City Prosecutor declined to prosecute due to conflicts of interest, and the Salt Lake City District Attorney’s Office also recused itself. The Salt Lake City Prosecutor’s Office ultimately accepted the case and filed misdemeanor charges against Peterson for the incident that occurred in West Jordan. Peterson moved to dismiss, arguing the Salt Lake City Prosecutor lacked authority to prosecute crimes occurring outside Salt Lake City limits.

Key Legal Issues

The central issue was whether Utah Code section 10-3-928 permits a city attorney to prosecute state law violations that occurred outside their municipal boundaries when conflict-of-interest situations prevent the geographically appropriate prosecutor from handling the case.

Court’s Analysis and Holding

The Utah Supreme Court applied statutory interpretation principles, examining the plain language of section 10-3-928. The statute permits city attorneys to “prosecute, under state law, infractions and misdemeanors occurring within the boundaries of the municipality.” The court emphasized that city attorneys are not constitutional “public prosecutors” but receive limited prosecutorial authority from the legislature. The court rejected the trial court’s reasoning that conflict-of-interest situations create exceptions to geographical limitations, holding that neither prosecutors nor courts can expand statutorily defined authority.

Practice Implications

This decision establishes clear boundaries for municipal prosecutorial jurisdiction. When conflicts of interest arise, proper alternatives include the Utah Attorney General’s office, which retains authority to prosecute cases statewide, or appointment of a prosecutor pro tempore under Article VIII, Section 16 of the Utah Constitution. Practitioners should ensure that prosecutorial authority matches the geographical location of alleged crimes, regardless of practical considerations like conflicts of interest.
