An appeal may be made to the City Council for any permit revocation or suspension under this chapter. The appeal shall be in writing and shall be filed with the City Clerk within ten days from the mailing to the applicant or licensee of the revocation or suspension from which the appeal is taken. Any such appeal shall specify the decision from which the appeal is taken and the grounds of the appeal. If the City Manager, or designee, has therefor conducted a hearing with respect to the decision, the City Council may determine the appeal on the basis of the transcript of said hearing, or may hold a public hearing de novo before the City Council itself, in its sound discretion. If there has been no prior hearing before the City Manager, or designee, with respect to the decision appealed from, the City Council shall hold a public hearing on the appeal. At any such hearing, the applicant shall be entitled to be present, to be represented by an attorney, and to present witnesses and testimony in support of the appeal. The decision of the City Council with respect to any appeal shall be final.
