In addition to other fines and penalties that may be imposed herein, the city, acting by its council may, at anytime, upon a hearing held not less than three days after written notice to licensee of the time and place thereof and upon proof of the conviction of any violation of any ordinance of the city of Vancouver or any state or federal law or for other cause deemed by them sufficient, revoke any license issued by virtue hereof. This power to revoke is cumulative and shall not impair the right of the city to act under any other ordinance now or hereafter in effect regulating the procedure for revocation of licenses. (Ord. M-110 §9, 1953)
