If the Chief of Police finds that any person holding an escort bureau or introductory service permit under the provisions of this chapter has violated any of the provisions of this chapter or conducts such business in such a manner as would have been grounds for denial of a permit as set forth in subsection H of Section 7.140.070, or if the Chief of Police finds that any person holding an escort permit is engaging in behavior or actions which violate any of the provisions of this chapter or which would have been grounds for denial of a permit as set forth in subsection F of Section 7.140.130, he may suspend or revoke the permit. No such suspension or revocation shall become effective until the permit holder has been notified in writing of the right of such permit holder to appeal the suspension or revocation to the City Manager within twenty days of such suspension or revocation. Notification of the permit holder shall be made either by personal delivery or by certified or registered mail, return receipt requested, addressed to the permit holder at such permit holder's residence address as set forth on the application for a permit or renewal thereof. If a timely appeal is filed, the suspension or revocation shall be stayed and shall become effective only upon decision of the City Manager. Otherwise, the suspension or revocation shall become effective after the timely appeal period has expired. (Ord. 2456 § 1 (part), 1983).
