No new ordinance shall be construed or held to repeal a former ordinance, whether the former ordinance is expressly repealed or not, as to any offense committed against the former ordinance or as to any act done, any penalty, forfeiture or punishment so incurred or any right accrued, or claim arising under the former ordinance, or in any way whatsoever to affect any offense or act so committed or so done, or any penalty, forfeiture or punishment so incurred, or any right accrued or claim arising before the new ordinance takes effect, save only that proceedings thereafter shall conform as far as practicable to the ordinance in force at the time of the proceeding. If any penalty, forfeiture or punishment be mitigated by any provision of a new law or ordinance, the provision may, by consent of the party affected, be applied to any judgment pronounced after the new ordinances take effect. This section shall extend to all repeals either by express words or by implication, whether the repeal is in the ordinance making any new provisions upon the same subject or any other ordinance. Nothing contained in this or § 10.14 shall be construed as abating any action new pending under or by virtue of any general ordinance of the city, herein repealed; or as discontinuing, abating, modifying or altering any penalty accrued or to accrue, or as affecting the liability of any person, firm or corporation, or as waiving any right of the city under any section or provision of ordinances existing at the time of the passage of this code.
