In general, an appeal can be filed in either the U.S. Court of Appeals for the District of Columbia Circuit or the U.S. Court of Appeals for the circuit in which the regulated entity is located or has its principal place of business. See NGA § 19(b), 15 U.S.C. § 717r(b); FPA § 313(b), 16 U.S.C. § 825l(b); see also 28 U.S.C. § 2343 (venue in review of actions under the Interstate Commerce Act). An appeal of a final Commission order may not be brought in a U.S. District Court. In addition, jurisprudential considerations, such as standing, ripeness, and mootness, may apply.
