Rule 9 - Proceedings for persons arrested without a warrant on suspicion of a crime(a)Probable cause determination. (a)(1) A person arrested and delivered to a correctional facility without a warrant for an offense must be presented without unnecessary delay before a magistrate for the determination of probable cause and eligibility for pretrial release pursuant to Utah Code § 77-20-1.(a)(2) The arresting officer, custodial authority, or prosecutor with authority over the most serious offense for which defendant was arrested must, as soon as reasonably feasible but in no event longer than 24 hours after the arrest, present to a magistrate a sworn statement that contains the facts known to support probable cause to believe the defendant has committed a crime. The statement must contain any facts known to the affiant that are relevant to determining the appropriateness of precharge release and the conditions thereof.(a)(3) If available, the magistrate should also be presented the results of a validated pretrial risk assessment tool.(a)(4) The magistrate must review the information provided and determine if probable cause exists to believe the defendant committed the offense or offenses described. If the magistrate finds there is probable cause, the magistrate must determine if the person is eligible for pretrial release pursuant to Utah Code § 77-20-1. The magistrate will impose the least restrictive reasonably available conditions of release reasonably necessary to:(a)(4)(A) ensure the individual's appearance at future court proceedings;(a)(4)(B) ensure that the individual will not obstruct or attempt to obstruct the criminal justice process;(a)(4)(C) ensure the safety of any witnesses or victims of the offense allegedly committed by the individual; and(a)(4)(D) ensure the safety and welfare of the public and the community.(a)(5) If the magistrate finds the statement does not support probable cause to support the charges filed, the magistrate may determine what if any charges are supported, and proceed under paragraph (a)(4).(a)(6) If probable cause is not articulated for any charge, the magistrate must return the statement to the submitting authority indicating such.(a)(7) A statement that is verbally communicated by telephone must be reduced to a sworn written statement prior to presentment to the magistrate. The statement must be retained by the submitting authority and as soon as practicable, a copy shall be delivered to the magistrate who made the determination.(a)(8) The arrestee need not be present at the probable cause determination.(b)Magistrate availability. (b)(1) The information required in paragraph (a) may be presented to any magistrate, although if the judicial district has adopted a magistrate rotation, the presentment should be in accord with that schedule or rotation. If the arrestee is charged with a capital offense, the magistrate may not be a justice court judge.(b)(2) If a person is arrested in a county other than where the offense was alleged to have been committed, the arresting authority may present the person to a magistrate in the location arrested, or in the county where the crime was committed.(c)Time for review. (c)(1) Unless the time is extended at 24 hours after booking, if no probable cause determination and pretrial status order have been received by the custodial authority, the defendant must be released on the arrested charges on recognizance.(c)(2) During the 24 hours after arrest, for good cause shown an arresting officer, custodial authority, or prosecutor with authority over the most serious offense for which defendant was arrested may request an additional 24 hours to hold a defendant and prepare the probable cause statement or request for release conditions.(c)(3) If after 24 hours, the suspect remains in custody, an information must be filed without delay charging the suspect with offenses from the incident leading to the arrest.(c)(4)(A) If no information has been filed by 3:00pm on the fourth calendar day after the defendant was booked, the release conditions set under subsection (a)(4) shall revert to recognizance release.(c)(4)(B) The four day period in this subsection may be extended upon application of the prosecutor for a period of three more days, for good cause shown.(c)(4)(C) If the time periods in this subsection (c)(4)(A) and (c)(4)(B) expire on a weekend or legal holiday, the 58 period expires at 3:00pm on the next business day.(d)Other processes. Nothing in this rule is intended to preclude the accomplishment of other procedural processes at the time of the probable cause determination.Amended effective 5/1/2018; amended effective 11/18/2019; amended effective 10/1/2020.
