Any person aggrieved by any decision of the collector with respect to any provision of this chapter may appeal to the city council by filing a notice of appeal with the clerk of the council within fifteen days after notice of the decision of the collector. The city council shall thereupon fix a time and place for hearing such appeal not later than thirty days after the notice of appeal is received by the clerk. The clerk of the council shall give notice to such person of the time and place of hearing by serving it personally or by depositing it in the United States mail, postage prepaid, addressed to such person at his last known address. The city council shall have authority to determine all questions raised on such appeal. No such determination shall conflict with any substantive provision of the ordinance codified in this chapter.
