(A) Mandatory Disclosure. In addition to disclosures required by provisions of law other than MCL 767.94a, a party upon request must provide all other parties:(1) the names and addresses of all lay and expert witnesses whom the party may call at trial; in the alternative, a party may provide the name of the witness and make the witness available to the other party for interview; the witness list may be amended without leave of the court no later than 28 days before trial;(2) any written or recorded statement, including electronically recorded statements, pertaining to the case by a lay witness whom the party may call at trial, except that a defendant is not obliged to provide the defendant's own statement;(3) the curriculum vitae of an expert the party may call at trial and either a report by the expert or a written description of the substance of the proposed testimony of the expert, the expert's opinion, and the underlying basis of that opinion;(4) any criminal record that the party may use at trial to impeach a witness;(5) a description or list of criminal convictions, known to the defense attorney or prosecuting attorney, of any witness whom the party may call at trial; and(6) a description of and an opportunity to inspect any tangible physical evidence that the party may introduce at trial, including any document, photograph, or other paper, with copies to be provided on request. A party may request a hearing regarding any question of costs of reproduction, including the cost of providing copies of electronically recorded statements. On good cause shown, the court may order that a party be given the opportunity to test without destruction any tangible physical evidence.(B) Discovery of Information Known to the Prosecuting Attorney. Upon request, the prosecuting attorney must provide each defendant:(1) any exculpatory information or evidence known to the prosecuting attorney;(2) any police report and interrogation records concerning the case, except so much of a report as concerns a continuing investigation;(3) any written or recorded statements, including electronically recorded statements, by a defendant, codefendant, or accomplice pertaining to the case, even if that person is not a prospective witness at trial;(4) any affidavit, warrant, and return pertaining to a search or seizure in connection with the case; and(5) any plea agreement, grant of immunity, or other agreement for testimony in connection with the case.(C) Prohibited Discovery.(1) Notwithstanding any other provision of this rule, there is no right to discover information or evidence that is protected from disclosure by constitution, statute, or privilege, including information or evidence protected by a defendant's right against self-incrimination, except as provided in subrule (2).(2) If a defendant demonstrates a good-faith belief, grounded in articulable fact, that there is a reasonable probability that records protected by privilege are likely to contain material information necessary to the defense, the trial court shall conduct an in camera inspection of the records.(a) If the privilege is absolute, and the privilege holder refuses to waive the privilege to permit an in camera inspection, the trial court shall suppress or strike the privilege holder's testimony.(b) If the court is satisfied, following an in camera inspection, that the records reveal evidence necessary to the defense, the court shall direct that such evidence as is necessary to the defense be made available to defense counsel. If the privilege is absolute and the privilege holder refuses to waive the privilege to permit disclosure, the trial court shall suppress or strike the privilege holder's testimony.(c) Regardless of whether the court determines that the records should be made available to the defense, the court shall make findings sufficient to facilitate meaningful appellate review.(d) The court shall seal and preserve the records for review in the event of an appeal (i) by the defendant, on an interlocutory basis or following conviction, if the court determines that the records should not be made available to the defense, or(ii) by the prosecution, on an interlocutory basis, if the court determines that the records should be made available to the defense.(e) Records disclosed under this rule shall remain in the exclusive custody of counsel for the parties, shall be used only for the limited purpose approved by the court, and shall be subject to such other terms and conditions as the court may provide.(D) Excision. When some parts of material or information are discoverable and other parts are not discoverable, the party must disclose the discoverable parts and may excise the remainder. The party must inform the other party that nondiscoverable information has been excised and withheld. On motion, the court must conduct a hearing in camera to determine whether the reasons for excision are justifiable. If the court upholds the excision, it must seal and preserve the record of the hearing for review in the event of an appeal.(E) Protective Orders. On motion and a showing of good cause, the court may enter an appropriate protective order. In considering whether good cause exists, the court shall consider the parties' interests in a fair trial; the risk to any person of harm, undue annoyance, intimidation, embarrassment, or threats; the risk that evidence will be fabricated; and the need for secrecy regarding the identity of informants or other law enforcement matters. On motion, with notice to the other party, the court may permit the showing of good cause for a protective order to be made in camera. If the court grants a protective order, it must seal and preserve the record of the hearing for review in the event of an appeal.(F) Timing of Discovery. Unless otherwise ordered by the court, the prosecuting attorney must comply with the requirements of this rule within 21 days of a request under this rule and a defendant must comply with the requirements of this rule within 21 days of a request under this rule.(G) Copies. Except as ordered by the court on good cause shown, a party's obligation to provide a photograph or paper of any kind is satisfied by providing a clear copy.(H) Continuing Duty to Disclose. If at any time a party discovers additional information or material subject to disclosure under this rule, the party, without further request, must promptly notify the other party.(I) Modification. On good cause shown, the court may order a modification of the requirements and prohibitions of this rule.(J) Violation. If a party fails to comply with this rule, the court, in its discretion, may order the party to provide the discovery or permit the inspection of materials not previously disclosed, grant a continuance, prohibit the party from introducing in evidence the material not disclosed, or enter such other order as it deems just under the circumstances. Parties are encouraged to bring questions of noncompliance before the court at the earliest opportunity. Willful violation by counsel of an applicable discovery rule or an order issued pursuant thereto may subject counsel to appropriate sanctions by the court. An order of the court under this section is reviewable only for abuse of discretion.(K) Except as otherwise provided in MCR 2.302(B)(6), electronic materials are to be treated in the same manner as nonelectronic materials under this rule. Nothing in this rule shall be construed to conflict with MCL 600.2163a.
