Michigan Compiled Laws, Chapter 330. Mental Health Code § 330.1531

Sec. 531. (1) Every resident admitted by court order has the right to regular, adequate, and prompt review of his or her current status as an individual meeting the criteria for treatment. Six months after the date of an order of treatment, and every 6 months after that, the director of a facility to which a resident was admitted shall review the resident's status as an individual meeting the criteria for treatment.

(2) The results of each periodic review shall be made part of the resident's record, and shall be filed within 5 days of the review in the form of a written report with the court that ordered the resident's admission, and within the 5 days, notice of the results of the review shall be given by the facility to the resident, his or her attorney, and his or her nearest relative or guardian.

(3) If the report concludes that the resident continues to meet the criteria for treatment, and the resident or someone on his or her behalf objects to that conclusion, the resident has the right to a hearing and all other rights expressed or implied in sections 517 to 522  1 and may petition the court for discharge. The petition shall be presented to the court or a representative of the facility within 7 days, excluding Sundays and holidays, after the report is received. If the petition is presented to a representative of the facility, the representative shall transmit it to the court immediately.
