*25JUDGMENT
Per CuriamThis appeal was considered on the record from the United States District Court for the District of Columbia and on the briefs filed by the parties. See Fed. R. App. P. 34(a)(2); D.C. Cir. Rule 34(j). It is
ORDERED AND ADJUDGED that the district court’s order filed June 5, 2015 be affirmed. The district court correctly dismissed the complaint for lack of an Article III case or controversy. See Flast v. Cohen, 392 U.S. 83, 94, 88 S.Ct. 1942, 20 L.Ed.2d 947 (1968). ‘“[T]he oldest and most consistent thread in the federal law of justiciability is that the federal courts will not give advisory opinions.’ ” Pub. Serv. Elec. & Gas Co. v. FERC, 783 F.3d 1270, 1274 (D.C. Cir. 2015) (quoting Flast v. Cohen, 392 U.S. at 96, 88 S.Ct. 1942). Moreover, the district court correctly concluded that appellant failed to demonstrate an injury-in-fact as required for Article III standing. See Swanson Group Mfg., LLC v. Jewell, 790 F.3d 235, 242 (D.C. Cir. 2015) (“ ‘[Gjeneral averments’ and ‘conclu-sory allegations’ ... are ‘inadequate’ to demonstrate standing.” (quoting Friends of the Earth, Inc. v. Laidlaw Envtl. Servs. (TOC), Inc., 528 U.S. 167, 184, 120 S.Ct. 693, 145 L.Ed.2d 610 (2000))). Finally, the district court was also right that appellant was precluded from representing third-party claimants. “[A] party ‘generally must assert his own legal rights and interests, and cannot rest his claim to relief on the legal rights of third parties.’ ” Kowalski v. Tesmer, 543 U.S. 125, 129, 125 S.Ct. 564, 160 L.Ed.2d 519 (2004) (quoting Warth v. Seldin, 422 U.S. 490, 499, 95 S.Ct. 2197, 45 L.Ed.2d 343 (1975)).
