Mental health: recipient rights; rights violations investigations; modify. Amends sec. 778 of 1974 PA 258 (MCL 330.1778).

This bill updates Michigan's mental health code to establish stricter timelines and reporting requirements for investigating complaints about rights violations in mental health facilities. It mandates that investigations into abuse, neglect, serious injury, or death must begin within 24 hours and be completed within 90 days, while requiring the office to send written status updates every 30 days to all parties involved. The legislation also clarifies that investigations will use a "preponderance of the evidence" standard to determine if rights were violated and allows for reopening cases if new evidence emerges. These changes directly affect the state mental health office, mental health agencies, and individuals filing complaints on behalf of recipients.
