Sec. 313(b) of the Federal Power Act, 16 U.S.C.A. § 825l(b), provides that any party to a proceeding under this Act, aggrieved by an order issued by the Commission in such proceeding, may obtain a review of such order in an appropriate Circuit Court of Appeals, by filing in such court a written petition praying that the order of the Commission be modified or set aside. This method of judicial review is exclusive. Federal Power Commission v. Pacific Power & Light Co., 307 U.S. 156, 159, 59 S. Ct. 766, 83 L. Ed. 1180; Safe Harbor Water Power Corp. v. Federal Power Commission, 3 Cir., 124 F.2d 800, 804, certiorari denied, 316 U.S. 663, 62 S. Ct. 943, 86 L. Ed. 1740; Myers v. Bethlehem Shipbuilding Corp., 303 U.S. 41, 48-50, 58 S. Ct. 459, 82 L. Ed. 638; Miles Laboratories v. Federal Trade Commission, 78 U.S.App.D.C. 326, 328, 140 F.2d 683, certiorari denied, 322 U.S. 752, 64 S. Ct. 1263, 88 L. Ed. 1582; Black River Valley Broadcasts, Inc. v. McNinch et al., 69 App.D.C. 311, 314, 101 F.2d 235, certiorari denied, 307 U.S. 623, 59 S. Ct. 793, 83 L. Ed. 1501. The Federal Declaratory Judgment Act, 28 U.S.C.A. § 400, does not confer upon the court jurisdiction which it does not otherwise possess. Miles Laboratories v. Federal Trade Commission, supra; Bradley Lumber Co. v. National Labor Relations Board, 5 Cir., 84 F.2d 97, 100, certiorari denied, 299 U.S. 559, 57 S. Ct. 21, 81 L. Ed. 411. This court therefore does not have jurisdiction over the subject matter of the complaint.
The cross-claim is governed by the same principles. The Department and its Commissioners cannot escape them by failing to seek relief in the proceeding now pending on the Commission's docket, about which they complain. This they may do by filing a petition for intervention.
If they are allowed to intervene and are aggrieved by an order thereafter issued by the Commission, they may obtain a review of such order as set forth in Sec. 313(b) of the Federal Power Act, supra. If they petition to intervene and their petition is denied, they may obtain a review of such order denying their petition under Sec. 313(b), supra. Moreover, it should be pointed out that the administrative remedies under the Federal Power Act have not been exhausted, and 'no one is entitled to judicial relief for a supposed or threatened injury until the prescribed administrative remedy has been exhausted. That rule has been repeatedly acted on in cases where, as here, the contention is made that the administrative body lacked power over the subject matter.' Myers v. Bethlehem Shipbuilding Corp., supra (303 U.S. 41, 58 S. Ct. 459, 463); Miles Laboratories v. Federal Trade Commission, supra.
Finally, the substantive question raised by the plaintiffs and cross-claimants appears to have been settled adversely to their contention. Northwestern Electric Co. v. Federal Power Commission, 321 U.S. 119, 64 S. Ct. 451, 88 L. Ed. 596.
The motion of the Federal Power Commission and its Commissioners to dismiss the complaint and cross-claim therefore will be granted. Counsel for the Commission and its Commissioners will submit, on notice, appropriate order.
