The prosecutor in a criminal case shall:
Iowa. R. Prof. Cond. 32:3.8
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, that guilt is decided upon the basis of sufficient evidence, and that special precautions are taken to prevent and to rectify the conviction of innocent persons. The extent of mandated remedial action is a matter of debate and varies in different jurisdictions. See generally ABA Standards of Criminal Justice Relating to the Prosecution Function. Competent representation of the sovereignty may require a prosecutor to undertake some procedural and remedial measures as a matter of obligation. Applicable law may require other measures by the prosecutor, and knowing disregard of those obligations or a systematic abuse of prosecutorial discretion could constitute a violation of rule 32:8.4.
[2] A defendant may waive a preliminary hearing and thereby lose a valuable opportunity to challenge probable cause. Accordingly, prosecutors should not seek to obtain waivers of preliminary hearings or other important pretrial rights from unrepresented accused persons. Paragraph (c) does not apply, however, to an accused appearing pro se with the approval of the tribunal. Nor does it forbid the lawful questioning of an uncharged suspect who has knowingly waived the rights to counsel and silence. In addition, paragraph (c) does not apply to a defendant charged with a simple misdemeanor for which the prosecutor reasonably believes the defendant will not be incarcerated.
[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.
[4] Paragraph (e) is intended to limit the issuance of lawyer subpoenas in grand jury and other criminal proceedings to those situations in which there is a genuine need to intrude into the client-lawyer relationship.
[5] Paragraph (f) supplements rule 32:3.6, which prohibits extrajudicial statements that have a substantial likelihood of prejudicing an adjudicatory proceeding. In the context of a criminal prosecution, a prosecutor's extrajudicial statement can create the additional problem of increasing public condemnation of the accused. Although the announcement of an indictment, for example, will necessarily have severe consequences for the accused, a prosecutor can, and should, avoid comments which have no legitimate law enforcement purpose and have a substantial likelihood of increasing public opprobrium of the accused. Nothing in this comment is intended to restrict the statements which a prosecutor may make which comply with rule 32:3.6(b) or 32:3.6(c) and with rule 32:3.6(e).
[6] Like other lawyers, prosecutors are subject to rules 32:5.1 and 32:5.3, which relate to responsibilities regarding lawyers and nonlawyers who work for or are associated with the lawyer's office. Paragraph (f) reminds the prosecutor of the importance of these obligations in connection with the unique dangers of improper extrajudicial statements in a criminal case. In addition, paragraph (f) requires a prosecutor to exercise reasonable care to prevent persons assisting or associated with the prosecutor from making improper extrajudicial statements, even when such persons are not under the direct supervision of the prosecutor. Ordinarily, the reasonable care standard will be satisfied if the prosecutor issues the appropriate cautions to law-enforcement personnel and other relevant individuals.
[7] When a prosecutor knows of new, credible, and material evidence creating a reasonable likelihood that a person outside the prosecutor's jurisdiction was convicted of a crime that the person did not commit, paragraph (g) requires prompt disclosure to the court or other appropriate authority, such as the chief prosecutor of the jurisdiction where the conviction occurred. If the conviction was obtained in the prosecutor's jurisdiction, paragraph (g) requires the prosecutor to promptly disclose the evidence to the court and, absent court-authorized delay, to the defendant. Consistent with the objectives of rules 32:4.2 and 32:4.3, disclosure to a represented defendant must be made through the defendant's counsel, and, in the case of an unrepresented defendant, would ordinarily be accompanied by a request to a court for the appointment of counsel to assist the defendant in taking such legal measures as may be appropriate.
[8] Under paragraph (h), once the prosecutor knows of clear and convincing evidence that the defendant was convicted of an offense that the defendant did not commit, the prosecutor must seek to remedy the conviction. Necessary steps may include disclosure of the evidence to the defendant, requesting that the court appoint counsel for an unrepresented indigent defendant, and, where appropriate, notifying the court that the prosecutor has knowledge that the defendant did not commit the offense of which the defendant was convicted.
[9] A prosecutor's independent judgment, made in good faith, that the new evidence is not of such nature as to trigger the obligations of paragraphs (g) and (h), though subsequently determined to have been erroneous, does not constitute a violation of this rule.
