Georgia Code Title 36. Local Government § 36-60-26

(a) It shall be unlawful for any county, municipal corporation, or other issuing authority to issue any backdated license, permit, or other authorizing document, including but not limited to any building permit, sign permit, occupation tax certificate, zoning action, subdivision of land, final plat, or other similar authorization, in any territorial or geographic area which, due to the formation of a county, incorporation of a municipality, annexation or deannexation of territory, or other action, is no longer within the regulatory jurisdiction of said issuing authority. For purposes of this Code section, a license, permit, or other authorizing document shall be considered to be backdated if it in any manner purports to have been issued or have become effective prior to its actual date of issuance.

(b) A license, permit, or other authorizing document in violation of this Code section shall be void in its entirety, and no person shall acquire any rights thereunder.

(c) Any county or municipal officer or employee who knowingly violates this Code section shall be upon conviction guilty of a misdemeanor.
