Modifies provisions relating to civil detention procedures

HB 543 removes the notarization requirement for applications seeking emergency mental health detention, allowing any adult (including family members or medical staff) to file a sworn statement alleging a mental health crisis. It specifies that applications must detail factual evidence of imminent harm and be submitted to a court with probate jurisdiction. If probable cause is established, peace officers may detain individuals for up to 96 hours for evaluation at a mental health facility, with medical professionals also permitted to initiate this process based on their observations. The bill maintains existing safeguards requiring probable cause and the right to be heard, but streamlines the initial filing process by eliminating notarization for applications filed by peace officers, healthcare providers, or hospital staff.
