by probable cause;
(b) [RESERVED]
(c) [RESERVED]
(d) fail to make timely disclosure to the defense of all evidence or information

mitigating information known to the prosecutor, except when the prosecutor is relieved of
this responsibility by an order of the tribunal;
(e) 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 all of

(1) the information sought is not protected from disclosure by any

ongoing investigation or prosecution;
(3) there is no other feasible alternative to obtain the information.

History
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 justice and that guilt is decided upon the basis of sufficient evidence. 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 8.4. A prosecutor also is subject to other applicable rules such as Rules 3.6, 4.2, 4.3, 5.1, and 5.3. [2] [RESERVED] [3] The exception in division (d) recognizes that a prosecutor may seek an appropriate 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] Division (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] [RESERVED] [6] [RESERVED] Comparison to former Ohio Code of Professional Responsibility Rule 3.8(a) corresponds to DR 7- 103(A) (no charges without probable cause), and Rule 3.8(d) corresponds to DR 7- 103(B) (disclose evidence that exonerates defendant or mitigates degree of offense or punishment). EC 7-13 recognizes the distinctive role of prosecutors: The responsibility of a public prosecutor differs from that of the usual advocate; his [her] duty is to seek justice, not merely to convict. This special duty exists because: (1) the prosecutor represents the sovereign and therefore should use restraint in the discretionary exercise of governmental powers, such as in the selection of cases to prosecute; (2) during trial the prosecutor is not only an advocate but he [she] also may make decisions normally made by an individual client, and those affecting the public interest should be fair to all; and (3) in our system of criminal justice the accused is to be given the benefit of all reasonable doubt. Comparison to ABA Model Rules of Professional Conduct Rule 3.8 modifies Model Rule 3.8 as follows: • The introductory phrase of the rule is reworded to state a prohibition, consistent with other rules; • Division (a) is expanded to prohibit either the pursuit or prosecution of unsupported charges and, thus, would include grand jury proceedings; • Division (b) is deleted because ensuring that the defendant is advised about the right to counsel is a police and judicial function and because Rule 4.3 sets forth the duties of all lawyers in dealing with unrepresented persons; • Division (c) is deleted because of its breadth and potential adverse impact on defendants who seek continuances that would be beneficial to their case or who seek to participate in diversion programs; • Division (d) is modified to comport with Ohio law; • Division (f) is deleted because a prosecutor, like all lawyers, is subject to Rule 3.6.
