While on the Board, Harold also voted to approve or deny renewal and/or issuance of bail bond licenses, heard complaints from the general public about bonding matters, and voted when necessary to suspend or revoke bonding licenses of those violating the rules. Harold also served on the Local Rules Committee, helping to formulate and update the local rules of the Board.
