Change name of mental health advisory council to behavioral health advisory council

This bill amends state law to rename the Mental Health Oversight Advisory Council to the Behavioral Health Advisory Council. The change directly affects the advisory council that provides input to the Department of Public Health and Human Services on public mental health system development and management. The key provision updates the official name of the council in the Montana Code Annotated while maintaining its existing composition requirements, which include consumer members, advocates, providers, legislators, and department representatives. No other operational changes to the council's structure, membership, or functions are included in this legislation.
