From Detroit Free Press:
The Michigan Freedom of Information Act (FOIA) sets requirements for disclosure of records by all public bodies in the state. To obtain records, any citizen can submit a request in writing and note that the information is being sought under the act.
The act applies to all kinds of public institutions, including local and state government agencies, public universities and school boards. Among the records people can seek: the salaries of public employees, police reports and e-mails sent between government employees.
