Joint tariffs

Sec. 17. TARIFFS OF JOINT AGENTS. (a) Joint tariffs issued by joint agents. An agent for certain carriers may join with not more than

two other agents for other carriers in the issuance of tariffs. This may be done without each of such agents having powers of attorney from all of the

carriers parties to the tariff as required by Rule 3(b), provided each carrier is shown as participating under authority issued to one of such agents.

In such cases, each agent acts for the carriers that have given him powers of attorney or have given concurrences to the carriers issuing powers of

attorney and for such lines only.

(b) P.S.C.I. numbers and filing. Such publication shall bear a separate P.S.C.I. number in the series of each agent and each of the agents

shall file the publication and each and every supplement thereto for and on behalf of the carriers for which he is agent, as if it were his individual

publication on behalf of those carriers alone.

(c) Tariffs and supplements must be identical and must be filed under one cover. The tariff filed by one agent is not a complete publication

properly authorized by all carriers named therein. It is a complement of the tariff filed by each agent, and, therefore, identical copies of each tariff

and of each supplement thereto, must be filed by each agent. As each agent will file the tariff for the carriers which he lawfully represents, the cross

exchange of concurrences between all of the different carriers represented by each agent will not be necessary as to that tariff. In order to avoid

complications, all copies of each publication, accompanied by a letter of transmittal signed by each agent, shall be filed under one cover by one agent.

A tariff filed by one agent shall not be amended to show an additional agent as participating in issuance thereof except upon reissue of the tariff;

nor shall a tariff issued by joint agents be converted into one issued by a lesser number of agents except by reissue.

(d) List of participating carriers. Each publication issued by two or three agents jointly shall show one complete alphabetical list of

participating carriers indicating the carriers from which each of the agents has power of attorney, by showing in separate columns the form and

number of the authority granted to each, and also indicating the carriers that participate under concurrences to any of the carriers for which one of

the agents acts, by showing in an additional column the form and number of such concurrences together with appropriate reference marks to indicate

the carriers to whom the concurrences are given.
