In cities of the first class, all medallion holders shall utilize the services of a centralized dispatch system. Any owner of a centralized dispatch system shall make such system available to all medallion holders for a reasonable fee, as described in a rate schedule to be filed with the authority. The authority, in its discretion, may review the rate schedules of dispatch associations to determine if rates charged discriminate against new applicants. Medallion holders shall utilize only centralized dispatch systems that are in conformance with authority rules and regulations. Medallion holders shall have no obligation to use any particular centralized dispatch system.
