Mich. Comp. Laws § 280.159
Should any or all of the persons so appointed as a board of review neglect or refuse to serve or be unable to act, the commissioner shall adjourn the hearing for a sufficient length of time, not exceeding in all 10 days, to enable him to apply to the probate court, for the appointment of other persons to act on such board of review and shall make public announcement of the time and place of such adjournment. The review shall thereupon be deemed a continuous proceeding and no further notice shall be required. The probate court shall upon the showing being made, either that any or all the persons appointed as aforesaid have neglected, refused or were unable to act as the case may be and of the adjourned day of meeting, at once by order appoint such other person or persons duly qualified to fill such vacancy. And the commissioner shall notify the person or persons so appointed to fill such vacancy of his appointment and of the adjourned day of meeting. The person so appointed shall have the same power and perform the same duties as are herein provided for the board of review in the first instance.
