Mental Health Regional Commissions; authorize boards of supervisors to agree to board compositions.

HB 1530 allows county boards of supervisors in Mississippi to agree on alternative membership structures for mental health regional commissions, rather than requiring each county to appoint one representative. If all participating county boards adopt resolutions agreeing to a different composition (e.g., varying numbers of members per county), the commission can operate under that agreed-upon structure. This bill directly affects county boards of supervisors and the mental health regional commissions they oversee. The key change is replacing the default appointment rule with a requirement for unanimous county board consent to modify the commission’s makeup.
