The Council may revoke the taxicab license of any holder upon finding that such holder has violated any provision of this chapter. Written notice of intention to revoke together with a statement of the reasons therefore shall be given to the holder not less than seven days nor more than twenty-one days before the final hearing on the proposal to revoke. The failure of the holder to file written objections thereto more than forty-eight hours prior to the time for hearing shall constitute sufficient evidence of the violation so charged that the Council may revoke without a full hearing. (Ord. 1439, 1978)
