The prosecutor in a criminal case shall:
Utah. Sup. Ct. R. Prof. Prac. 3.8
Comment
[1] A prosecutor has the responsibility of a minister of justice and not simply that of an advocate. This responsibility carries with it specific obligations to see that the defendant is accorded procedural justice and that guilt is decided upon the basis of sufficient evidence. Precisely how far the prosecutor is required to go in this direction is a matter of debate and varies in different jurisdictions. See Rule 3.3(d), governing ex parte proceedings, among which grand jury proceedings are included. Applicable law may require other measures by the prosecutor and knowing disregard of those obligations or systematic abuse of prosecutorial discretion could constitute a violation of Rule 8.4.
[2] Paragraph (c) does not apply to an accused appearing pro se with the approval of the tribunal. Nor does it forbid the lawful questioning of a suspect who has knowingly waived the rights to counsel and silence.
[3] The exception in paragraph (d) recognizes that a prosecutor may seek an appropriate protective order from the tribunal if disclosure of information to the defense could result in substantial harm to an individual or to the public interest.
[3a] Utah has not adopted the ABA version of Rule 3.8. ABA Model Rule 3.8(d), requiring the prosecution to inform the tribunal of mitigating information related to sentencing, creates an unreasonable burden and is not deemed workable where the same information is required to be disclosed to the defense counsel who should be in the best position to decide what to present to the tribunal. The ABA's paragraph (e) regarding limitations on subpoenaing lawyers to grand juries or other legal proceedings is viewed as unnecessary, as there are adequate safeguards in place for federal prosecutors, and the Utah criminal justice system does not typically use the grand jury procedure. Utah has not adopted the ABA's proposed paragraph (f), because the changes are either unnecessary because of, or are potentially inconsistent with, the provisions of Rule 3.6.
