Senate Bill 1456 amends Chapter 68 of the Private Acts of 1937, specifically updating Section (3)(a) by changing the required percentage from "eighty-five percent (85%)" to "ninety-two percent (92%)". This adjustment reflects a significant increase in the percentage, which may impact the operations or requirements previously established under the law.

The bill stipulates that it will only take effect if approved by a two-thirds (2/3) vote of the legislative body of Hardeman County. The outcome of this vote must be proclaimed by the presiding officer and certified to the secretary of state, as outlined in Tennessee Code Annotated, Title 8, Chapter 3, Part 2. While the bill will become effective immediately for the purpose of approval or rejection, it will only be fully effective for other purposes once the legislative approval is secured.
