If the superintendent is of the opinion from his investigation that the character and general fitness of the persons named as stockholders or executive officers are such as not to command the confidence of the community in which such bank is proposed to be located or that there is not a sufficient business to support said bank in said community or that the convenience or needs of said community shall not be served, he shall issue under his hand and official seal, a refusal to permit the incorporation of the proposed bank and a copy of his refusal shall be filed in the superintendent's office, and the refusal and the proposed certificate of incorporation shall be returned to the proposed incorporators or their agent. No right of appeal to the Banking Board exists except upon refusal of the superintendent to permit incorporation. Any proposed stockholder or individual may appeal from such refusal of the superintendent by written notice of appeal filed with the superintendent within 28 days of the notice of refusal to the Banking Board. The Banking Board may take evidence and examine witnesses with respect to the propriety and justice vel non of said refusal and may make such findings and orders as may be necessary either to confirm said refusal or to permit the incorporation of such bank. Full power and authority is hereby vested in the State Banking Board to review, revise, and reverse or confirm any ruling or finding or order of the superintendent denying the establishment of state banks and to take evidence and examine witnesses of all parties touching such matters. The Banking Board will notify all parties of its decision.
