Whenever there is filed with the Commission any new or revised charge, classification, regulation, or practice, the Commission may either upon complaint or upon its own initiative without complaint, upon reasonable notice, enter upon a hearing concerning the lawfulness thereof; and pending such hearing and the decision thereon the Commission, upon delivering to the carrier or carriers affected thereby a statement in writing of its reasons for such suspension, may suspend the operation of such charge, classification, regulation, or practice, in whole or in part but not for a longer period than five months beyond the time when it would otherwise go into effect; and after full hearing the Commission may make such order with reference thereto as would be proper in a proceeding initiated after such charge, classification, regulation, or practice had become effective. If the proceeding has not been concluded and an order made within the period of the suspension, the proposed new or revised charge, classification, regulation, or practice shall go into effect at the end of such period; but in case of a proposed charge for a new service or a revised charge, the Commission may by order require the interested carrier or carriers to keep accurate account of all amounts received by reason of such charge for a new service or revised charge, specifying by whom and in whose behalf such amounts are paid, and upon completion of the hearing and decision may by further order require the interested carrier or carriers to refund, with interest, to the persons in whose behalf such amounts were paid, such portion of such charge for a new service or revised charges as by its decision shall be found not justified. At any hearing involving a new or revised charge, or a proposed new or revised charge, the burden of proof to show that the new or revised charge, or proposed charge, is just and reasonable shall be upon the carrier, and the Commission shall give to the hearing and decision of such questions preference over all other questions pending before it and decide the same as speedily as possible.

(1) Whenever there is filed with the Commission any new or revised charge, classification, regulation, or practice, the Commission may either upon complaint or upon its own initiative without complaint, upon reasonable notice, enter upon a hearing concerning the lawfulness thereof; and pending such hearing and the decision thereon the Commission, upon delivering to the carrier or carriers affected thereby a statement in writing of its reasons for such suspension, may suspend the operation of such charge, classification, regulation, or practice, in whole or in part but not for a longer period than five months beyond the time when it would otherwise go into effect; and after full hearing the Commission may make such order with reference thereto as would be proper in a proceeding initiated after such charge, classification, regulation, or practice had become effective. If the proceeding has not been concluded and an order made within the period of the suspension, the proposed new or revised charge, classification, regulation, or practice shall go into effect at the end of such period; but in case of a proposed charge for a new service or a revised charge, the Commission may by order require the interested carrier or carriers to keep accurate account of all amounts received by reason of such charge for a new service or revised charge, specifying by whom and in whose behalf such amounts are paid, and upon completion of the hearing and decision may by further order require the interested carrier or carriers to refund, with interest, to the persons in whose behalf such amounts were paid, such portion of such charge for a new service or revised charges as by its decision shall be found not justified. At any hearing involving a new or revised charge, or a proposed new or revised charge, the burden of proof to show that the new or revised charge, or proposed charge, is just and reasonable shall be upon the carrier, and the Commission shall give to the hearing and decision of such questions preference over all other questions pending before it and decide the same as speedily as possible.

Except as provided in subparagraph (B), the Commission shall, with respect to any hearing under this section, issue an order concluding such hearing within 5 months after the date that the charge, classification, regulation, or practice subject to the hearing becomes effective.

(A) Except as provided in subparagraph (B), the Commission shall, with respect to any hearing under this section, issue an order concluding such hearing within 5 months after the date that the charge, classification, regulation, or practice subject to the hearing becomes effective.

(B) The Commission shall, with respect to any such hearing initiated prior to November 3, 1988, issue an order concluding the hearing not later than 12 months after November 3, 1988.

(C) Any order concluding a hearing under this section shall be a final order and may be appealed under section 402(a) of this title.

(3) A local exchange carrier may file with the Commission a new or revised charge, classification, regulation, or practice on a streamlined basis. Any such charge, classification, regulation, or practice shall be deemed lawful and shall be effective 7 days (in the case of a reduction in rates) or 15 days (in the case of an increase in rates) after the date on which it is filed with the Commission unless the Commission takes action under paragraph (1) before the end of that 7-day or 15-day period, as is appropriate.

Notwithstanding the provisions of subsection (a) of this section, the Commission may allow part of a charge, classification, regulation, or practice to go into effect, based upon a written showing by the carrier or carriers affected, and an opportunity for written comment thereon by affected persons, that such partial authorization is just, fair, and reasonable. Additionally, or in combination with a partial authorization, the Commission, upon a similar showing, may allow all or part of a charge, classification, regulation, or practice to go into effect on a temporary basis pending further order of the Commission. Authorizations of temporary new or increased charges may include an accounting order of the type provided for in subsection (a).
