House Bill 50 amends the governance structure of the City of Celina by updating the election and composition of its Board of Mayor and Aldermen. The bill changes the election date for the mayor and aldermen from the first Tuesday in June 1993 to the first Tuesday in June 2025, and increases the number of aldermen from three to five. Additionally, it modifies 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 revises the voting requirements within the board, changing the requirement for passing motions, resolutions, or ordinances from an affirmative vote of at least two members to a majority of the board. This legislation will only take effect if approved by a two-thirds vote of the legislative body of the City of Celina, with provisions for its immediate effectiveness for the purpose of approval or rejection.
