Mich. Comp. Laws § 767.4
If upon such inquiry the judge shall be satisfied that any offense has been committed and that there is probable cause to suspect any person to be guilty thereof, he may cause the apprehension of such person by proper process and, upon the return of such process served or executed, the judge having jurisdiction shall proceed with the case, matter or proceeding in like manner as upon formal complaint. The judge conducting the inquiry under section 3 shall be disqualified from acting as the examining magistrate in connection with the hearing on the complaint or indictment, or from presiding at any trial arising therefrom, or from hearing any motion to dismiss or quash any complaint or indictment, or from hearing any charge of contempt under section 5, except alleged contempt for neglect or refusal to appear in response to a summons or subpoena. If upon such inquiry the judge shall find from the evidence that there is probable cause to believe that any public officer, elective or appointive and subject to removal by law, has been guilty of misfeasance or malfeasance in office or wilful neglect of duty or of any other offense prescribed as a ground of removal, the judge shall make a written finding setting up the offense so found and shall serve said finding upon the public officer, public board or body having jurisdiction under the law to conduct removal proceedings against the officer. The finding shall be a sufficient complaint as a basis for removal of said officer and the public officer, public board or public body having jurisdiction of removal proceedings against the officer shall proceed in the method prescribed by law for a hearing and determination of said charges. Except in cases of prosecutions for contempt or perjury against witnesses who may have been summoned before the judge conducting such inquiry, or for the purpose of determining whether the testimony of a witness examined before the judge is consistent with or different from the testimony given by such witness before a court in any subsequent proceeding, or in cases of disciplinary action against attorneys and counselors in this state, any judge conducting the inquiry, any prosecuting attorney and other persons who may at the discretion of the judge be admitted to such inquiry, who shall while conducting such inquiry or while in the services of the judge or after his services with the judge shall have been discontinued, utter or publish any statement pertaining to any information or evidence involved in the inquiry, or who shall disclose the fact that any indictment for a felony has been found against any person not in custody or under recognizance, or who shall disclose that any person has been questioned or summoned in connection with the inquiry, who shall disclose or publish or cause to be published any of the proceedings of the inquiry otherwise than by issuing or executing processes prior to the indictment, or shall disclose, publish or cause to be published any comment, opinion or conclusions related to the proceedings of the inquiry, shall be guilty of a misdemeanor punishable by imprisonment in the county jail not more than 1 year or by a fine of not less than $100.00 nor more than $1,000.00, or both fine and imprisonment in the discretion of the court, and the offense when committed by a public official shall also constitute malfeasance in office. The limitations, restrictions and penalties relating to the uttering, publishing or disclosing of any statement pertaining to any information or evidence, imposed by this section, do not apply to disclosures of information or evidence made by a judge conducting such an investigation to another judge concurrently conducting an investigation as provided in section 3. Upon the termination of the inquiry if the judge shall make no presentment of crime or wrongdoing as to any person whose apprehension or removal from office he has not so caused, he may, in his discretion, with the consent of the person who may be named, file with the clerk of the county in which such inquiry has been conducted, a report of no finding of criminal guilt as to any person or persons involved in such inquiry, either as witness or otherwise, whose involvement in such inquiry has become public.
No inquiry or proceeding under this chapter shall continue longer than 6 months unless extended by specific order of the judge or his successor for an additional period not to exceed 6 months.
In the event any judge conducting such inquiry shall be unable to continue because of physical disability, disqualification, termination of office or death, the presiding circuit judge of Michigan shall appoint a successor.
