Michigan Compiled Laws, Chapter 780. Criminal Procedure § 780.861

Sec. 11. (1) A department of this state, a law enforcement agency, or a local unit of government may request the department of the attorney general to provide the confidential address, telephone number, and electronic mail address of a program participant if the requesting department of this state, a law enforcement agency, or a local unit of government requires access to the confidential address, telephone number, or electronic mail address of the program participant for a legitimate governmental purpose. A request may only be submitted under this subsection if the department of this state, the law enforcement agency, or the local unit of government was unsuccessful in contacting the program participant using the designated address. Upon receiving a request under this subsection, the department of the attorney general shall confirm whether an individual, minor, or ward is a program participant but may not disclose further information except as provided under subsections (3) and (4).

(2) Upon the filing of a request under this section and if the program participant is not identified in the request as a suspect in a criminal investigation, the department of the attorney general shall promptly provide the program participant with notice of the request.

(3) Subject to subsection (4), the department of the attorney general may grant the request submitted under subsection (1) if the department of the attorney general determines that disclosure of the confidential address, telephone number, or electronic mail address of the program participant to the requesting department of this state, law enforcement agency, or local unit of government is necessary for a legitimate governmental purpose.

(4) If a request submitted under subsection (1) is for the confidential address, telephone number, or electronic mail address of a minor, the department of the attorney general must consider if disclosure of the information requested is harmful to the program participant.

(5) Except as otherwise provided under section 21(2),  1 a person who receives a confidential address, telephone number, or electronic mail address of a program participant under this section shall not disclose that information to another person.
