(a) Nonpayment of Judgment. In the event of a final judgment or award by a court of record against the owner of a taxicab, for damages on account of bodily injury or death and/or for damage to property, if such judgment or award is not paid within thirty days thereafter, the Mayor shall forthwith revoke all licenses of all the taxicabs of such owner.
(b) Failure to Operate. Whenever any person holding one or more licenses for taxicabs fails to make a reasonable and consistent effort to operate any such licensed taxicab for a period of sixty days, the Mayor shall notify the holder of the license and the Mayor shall revoke the license for such taxicab. However, any such person who desires to discontinue the services of such taxicab or taxicabs for a short period of time, may do so for a period of not less than sixty days or more than 120 days by so notifying the Mayor and depositing with the Mayor the licenses for such taxicab or taxicabs. However, if such taxicab or taxicabs so discontinued from service are not placed in service at the expiration of such 120-day period, such license or licenses therefor shall be revoked.
