This is a petition for review of Federal Maritime Commission orders accepting for filing certain “through inter-modal container freight tariffs” submitted by Container Marine Lines (CML).1 Petitioner is the North Atlantic Westbound Frieght Association (NAWFA) — except for CML. This Conference consists of ocean carriers in the westbound trade between Great Britain and Eire and United States Atlantic ports. Respondent Commission moved in this court to remand the proceedings for reconsideration. Petitioner urged that such motion should be granted only if this court, pending Commission disposition of the proceedings, stayed the Commission order or enjoined CML from operating under the challenged tariff, and assured that the issues before the Commission in the reopened proceeding would include the issues before this court.

The challenged tariff incorporates a single-factor rate for containerized transport from inland points in Great Britain and Eire to United States Atlantic ports with CML assuming common carrier liability for both the land and water segments. The Commission held the NAWFA Conference agreement applicable only to port-to-port carriage and CML’s through intermodal carriage with complete liability a unique and distinct service not contemplated by the Conference agreement. This service, since not' within the agreement, would not have to *804conform to the comparable NAWFA tariff rate. The Commission did require CML to break out the port-to-port segment of the single-factor rate and found that any discrepancies between the Conference ocean rate and the equivalent portion of CML’s through rate were not “on their face so discriminatory or prejudicial as to be unlawful per se.”

The Commission thought a full evidentiary hearing unnecessary; rather, emphasizing the need for a prompt determination, it limited the proceedings to memoranda, affidavits, and oral argument. We are not required at this time to pass on the merits before us, including the procedural issue whether the Commission was required to hold an evidentiary hearing, for we think it is in the interest of justice to grant the Commission’s application that we enter an appropriate order permitting the Commission to consider the matter further.2 Therefore, petitioner’s appeal will be stayed pending the reopened proceedings before the Commission.

In remanding we assume the Commission will analyze the problems which have given this court concern — not only the construction and interpretation of the NAWFA Conference agreement and the significance of the factors which it determined made CML’s service unique and distinct, but also (assuming it adheres to the initial interpretation) the capacity of the Commission (a) to consider whether the over-water portion of CML’s rate differs from the NAWFA rate, and whether the difference, if any, is unreasonable, and/or reflects lack of bona fides in CML’s offering the single-factor rate while it continues as a member of the Conference, and (b) to provide effective relief in appropriate cases upon administrative consideration and informal investigation in the absence of formal hearing and order.2 3

The renewed motion for stay is denied, with leave to resubmit upon a proper showing if petitioner be so advised, for the reasons set forth in our opinion dated May 16, 1968.

So ordered.
