If at any time the chief of police finds that any person holding such a license has been convicted of a violation of any federal or state criminal law, or an ordinance of the city, from which it appears that such licensee is no longer of good moral character and reputation, or a careful and experienced driver, the chief of police shall forthwith make a written report of his findings to the city council and shall make recommendations as to the suspension or revocation of such license. The city council shall, before acting thereon, set a date for hearing upon the matter and notify the licensee, in writing, of such date of hearing and of the contents of such report, at least ten days in advance thereof. Such license may be suspended or revoked for such time and on such terms as shall be imposed by majority vote of members of the council present at such hearing. (Ord. 289, 1946)
