Tennessee Code Title 45. Banks and Financial Institutions § 45-3-1101

Every association may amend its charter in the manner set forth herein. Each proposed amendment, together with a certified copy of the authorizing resolution, shall be submitted to the commissioner for approval. If the commissioner finds that the proposed amendment is in conformity with the law, the commissioner shall, in writing, approve the amendment and shall send notice of approval of the amendment by registered or certified mail to the home office of the association not less than thirty (30) days after its receipt by the commissioner. Should the commissioner disapprove any amendment within the time specified, the commissioner shall state the disapproval, together with the written reasons therefor, and send the same by registered or certified mail to the home office of the association, giving the association, if appropriate under the circumstances, the opportunity to modify or change and resubmit the proposed amendment so as to obviate the commissioner's objections. In the event that the commissioner disapproves the amendment after the resubmission by the association, the commissioner shall send written notice of the final disapproval by registered or certified mail to the home office of the association. Failure to send notice of approval or disapproval within the time specified shall be deemed to constitute approval of the proposed amendment by the commissioner.
