House Bill 50 proposes amendments to the governance structure of the City of Celina, Tennessee, by modifying the election process and the composition of the Board of Mayor and Aldermen. The bill changes the date of the next election for mayor and aldermen from June 1993 to June 2025, increasing the number of aldermen from three to five. Additionally, it revises the composition of the Board of Mayor and Aldermen to include five aldermen instead of three, thereby expanding the legislative body responsible for the city's corporate and legislative powers.

Furthermore, the bill alters the voting requirements within the board, changing the threshold for passing motions, resolutions, or ordinances from an affirmative vote of at least two members to a majority of the board. The enactment of this bill is contingent upon a two-thirds approval vote from the legislative body of the City of Celina, with provisions for immediate effectiveness for the approval process while other provisions will take effect as specified.
