(A) A city licensee who has a valid city wholesale or retail distilled spirits, wine, or malt beverage license must conduct the actions, business, and transactions authorized thereby upon the licensed premises.
(B) When no such actions, business, or transactions are conducted thereon for a period of 90 consecutive calendar days, the city license therefor shall become null and void and revoked by the City Administrator unless:
(1) The city licensee is unable to continue in business at the premises for which a license is issued due to an act of God; casualty; the acquisition of the premises by any federal, state, city, or other governmental agency under power of eminent domain; acquisition of any private corporation through its power of eminent domain granted to it, whether such acquisition is voluntary or involuntary; or loss of lease through failure of the landlord to renew the existing lease; and
(2) Prior to the discontinuance of business at the licensed premises or immediately thereupon if such is due to an act of God, the city licensee delivers to the City Administrator a written statement signed by the city licensee and verified by the oath or affirmation thereof indicating the discontinuance of business at the licensed premises for any of the causes or reasons described herein.
