Alleged errors in amounts claimed to be due the city may be appealed to a committee comprised of the assessor, the clerk and the treasurer-comptroller or their designees. The committee shall have no authority to review any matter for which a review or appeal procedure has been provided by statute or other ordinance. Within five (5) days of being informed of an amount claimed due, the applicant seeking review shall pay the amount claimed and file a written notice of appeal with the clerk stating the basis for the appeal and specifying the alleged error. Upon payment, the applicant may file the application for the license or permit if otherwise qualified. As soon as practicable, the committee shall hold a hearing at which the applicant shall present evidence to substantiate the claimed error, call witnesses in his/her/its own behalf, may cross examine witnesses and may be represented by legal counsel. After holding the hearing, the committee shall by majority vote make findings of fact and conclusions and shall correct any established errors. Any amount improperly required paid shall be refunded promptly, together with interest at the rate of twelve percent (12%) per annum from the date the amount was paid to the city to the date of refund. (1975 Code Ch. 13 § XXVI)
