Senate Bill 1489 revises the governance structure of the Town of Mason by updating Chapter 120 of the Private Acts of 1915. The bill establishes a governing body composed of a Mayor and six Aldermen, introduces specific residency requirements for candidates, and outlines procedures for filling vacancies. It also modifies the timing of the oath of office ceremony to the first Monday in December following the election, contingent upon certification by the County Election Commission. Additionally, the bill clarifies the legislative powers of the Board of Mayor and Aldermen, establishes quorum requirements for meetings, and mandates the adoption of parliamentary procedures based on Robert's Rules of Order.

The bill further details the roles of the Town Attorney and Town Recorder, specifying that the Town Attorney will be appointed by the Board to oversee litigation and legal matters, while the Town Recorder will maintain public records and prepare meeting minutes. It also introduces new personnel policies governing employee regulations, which must be reviewed every five years and made accessible to all employees. The bill will take effect upon a two-thirds vote of the Town's legislative body, with certain provisions effective immediately for public welfare purposes.
