AB 866 revises rules for county sheriff offices and undersheriff appointments across the state. It creates new requirements for appointing an undersheriff (who must be a certified law enforcement officer and county resident), clarifies succession rules when the sheriff is absent or incapacitated, and ensures deputies returning from undersheriff roles retain their prior pay and seniority. The bill directly affects county sheriffs, undersheriffs, county clerks handling vacancy procedures, and deputy sheriffs. Key provisions include mandating written appointment records, defining when an undersheriff acts as sheriff, and requiring counties to return deputies to their previous positions after undersheriff service.
