    SOUTHERN NATURAL GAS COMPANY, Petitioner, v. FEDERAL POWER COMMISSION, Respondent, United Gas Pipe Line Company, Intervenor.
    No. 19684.
    Unjíed States Court of Appeals District of Columbia Circuit.
    Argued April 20, 1966.
    Decided May 5, 1966.
    Mr. Peter G. Smith, with whom Messrs. William S. Tarver and Lewis Carroll, Birmingham, Ala., were on the brief, for petitioner.
    Mr. Joel Yohalem, Atty., F.P.C., with whom Messrs. Richard A. Solomon, Gen. Counsel, Howard E. Wahrenbrock, Sol., and Abraham R. Spalter, Asst. Gen. Counsel, F.P.C., were on the brief, for respondent.
    Mr. Thomas Fletcher, Houston, Tex., for intervenor.
    Before Burger, Wright and Tamm, Circuit Judges.
   PER CURIAM:

This appeal concerns the lawful rate for transportation of natural gas by United Gas Pipe Line Company for Southern Natural Gas Company during the period May 1, 1963, through May 25, 1965. Petitioner contends that the rate filed, charged and collected by United was unilaterally imposed and is therefore void under United Gas Pipe Line Co. v. Mobile Gas Service Corp., 350 U.S. 332, 76 S.Ct. 373, 100 L.Ed. 373 (1956), and Tyler Gas Service Company v. Federal Power Comm., 101 U.S.App.D.C. 184, 247 F.2d 590, cert. denied, sub nom. United Gas Pipe Line Co. v. Tyler Gas Service Co., 355 U.S. 895, 78 S.Ct. 263, 2 L.Ed.2d 193 (1957). We agree with the Commission that the rate, however imposed initially, was thereafter bilaterally agreed upon and, consequently, was not void under the principles announced in the Mobile and Tyler cases.

Affirmed.
