Senate Bill 1456 amends Chapter 68 of the Private Acts of 1937, as previously modified by Chapter 63 of the Private Acts of 2003, specifically addressing provisions related to Hardeman County. The bill proposes to change the percentage specified in Section (3)(a) from "eighty-five percent (85%)" to "ninety-two percent (92%)". This adjustment reflects an increase in the percentage, which may impact the financial or operational parameters set forth in the original legislation.

Additionally, the bill stipulates that it will only take effect if approved by a two-thirds (2/3) vote of the Hardeman County legislative body. The presiding officer of the legislative body is responsible for proclaiming the approval or disapproval of the act and certifying it to the secretary of state, in accordance with Tennessee Code Annotated, Title 8, Chapter 3, Part 2. The act will be effective upon becoming law for the purpose of approval or rejection, while for all other purposes, it will take effect as outlined in the approval process.
