Rules of Professional Conduct
ER 3.8. Special Responsibilities of a Prosecutor
The prosecutor in a criminal case shall:
(a) refrain from prosecuting a charge that the prosecutor knows is not supported by probable cause;
(b) make reasonable efforts to assure that the accused has been advised of the right to, and the procedure for obtaining, counsel and has been given reasonable opportunity to obtain counsel;
(c) not seek to obtain from an unrepresented accused a waiver of important pretrial rights, such as the right to a preliminary hearing;
(d) make timely disclosure to the defense of all evidence or information known to the prosecutor that tends to negate the guilt of the accused or mitigates the offense, and, in connection with sentencing, disclose to the defense and to the tribunal all unprivileged mitigating information known to the prosecutor, except when the prosecutor is relieved of this responsibility by a protective order of the tribunal;
(e) not subpoena a lawyer in a grand jury or other criminal proceeding to present evidence about a past or present client unless the prosecutor reasonably believes:
(1) the information sought is not protected from disclosure by any applicable privilege;
(2) the evidence sought is essential to the successful completion of any ongoing investigation or prosecution; and
(3) there is no other feasible alternative to obtain the information;
(f) except for statements that are necessary to inform the public of the nature and extent of the prosecutor's action and that serve a legitimate law enforcement purpose, refrain from making extrajudicial comments that have a substantial likelihood of heightening public condemnation of the accused and exercise reasonable care to prevent investigators, law enforcement personnel, employees or other persons assisting or associated with the prosecutor in a criminal case from making an extrajudicial statement that the prosecutor would be prohibited from making under ER 3.6 or this Rule.
(g) When a prosecutor knows of new, credible, and material evidence creating a reasonable likelihood that a convicted defendant did not commit an offense of which the defendant was convicted, the prosecutor shall:
(1) promptly disclose that evidence to the court in which the defendant was convicted and to the corresponding prosecutorial authority, and to defendant's counsel or, if defendant is not represented, the defendant and the indigent defense appointing authority in the jurisdiction, and
(2) if the judgment of conviction was entered by a court in which the prosecutor exercises prosecutorial authority, make reasonable efforts to inquire into the matter or to refer the matter to the appropriate law enforcement or prosecutorial agency for its investigation into the matter.
(h) When a prosecutor knows of clear and convincing evidence establishing that a defendant in the prosecutor's jurisdiction was convicted of an offense that the defendant did not commit, the prosecutor shall take appropriate steps, including giving notice to the victim, to set aside the conviction.
(i) A prosecutor who concludes in good faith that information is not subject to subsections (g) or (h) of this Rule does not violate those subsections even if this conclusion is later determined to have been erroneous.
 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.
 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.
 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.
 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.
 Paragraph (f) supplements ER 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 ER 3.6 (b) or (c).
 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.
 Evidence is considered new when it was unknown to a trial prosecutor at the time the conviction was entered or, if known to a trial prosecutor, was not disclosed to the defense, either deliberately or inadvertently.
