er a right of action is created by some other source of federal law. In re Estate of Ferdinand Marcos, Human Rights Litig., 25 F.3d 1467, 1474-75 (9th Cir.1994) (“Marcos II”); see also Montana-Dakota Util. Co. v. Northwestern Pub. Serv. Co., 341 U.S. 246, 249, 71 S.Ct. 692, 95 L.Ed. 912 (1951) (“The Judicial Code, in vesting jurisdiction in the District Courts, does not create causes of action, but only confers jurisdiction to adjudicate those arising from other sources which satisfy its limiting provisions.”). Thus, for jurisdiction to exist under § 1331 over Plaintiffs’ “crimes against humanity” cause of action, a source of federal law other than § 1331 must give rise to a private right of action for the violations of international law they allege.
Plaintiffs contend there are two such sources: the law of nations, as it is incorporated into the laws of the United States, and treaties to which the United States is a party. These arguments are addressed separately.
Laws op the United States
Plaintiffs argue first that a right of action exists under the “laws ... of the United States.” Specifically, Plaintiffs assert that non-consensual medical experimentation violates the law of nations and, therefore, the laws of the United States. So far, Plaintiffs rest on solid ground. See The Paquete Habana, 175 U.S. 677, 700, 20 S.Ct. 290, 44 L.Ed. 320 (1900) (“International law is part of our law, and must be ascertained and administered by the courts of justice of appropriate jurisdiction as often as questions of right depending upon it are duly presented for their determination."); Marcos II, 25 F.3d at 1473-74 (prohibition of torture is a jus cogens norm of international law, the violation of which establishes federal jurisdiction over tort claims brought under the cause of action created for such claims by 28 U.S.C. § 1350); United States v. Brandt, (The Medical Case), 2 Trials of War Criminals Before the Nuremberg Tribunals Under Control of Council Law No. 10, p. 181 (1949) (elaborating Nuremberg Code, which prohibits non-consensual medical experimentation); International Covenant on Civil and Political Rights, Art. 7, Annex, to G.A. Res. 2200, 21 U.N. GAOR Supp. (No. 16) U.N. Doc. A/6316 (1966) (equating non-consensual medical experimentation to torture).
Plaintiffs’ argument loses its footing at the critical next step: demonstrating the law of nations gives rise to a private right of action that applies to the allegations in this case. The law of nations ' itself does not create such a right of action because “[international law does not require any particular reaction to violations of law ____ Whether and how the United States wishes to react to such violations are domestic questions.” Marcos II, 25 F.3d at 1475 (internal quotation omitted); but compare Tel-Oren v. Libyan Arab Republic, 726 F.2d 774, 777-78 (D.C.Cir.1984) (Edwards, J., concurring) (source of Marcos II quotation) with id. at 816-19 (Bork, J., concurring) (suggesting that law of nations may give rise to self-executing' individual rights in extraordinary circumstances). Additionally, Plaintiffs point to no municipal authority that expressly creates a private right of action for international law’s prohibition on non-consensual medical experimentation, Instead, the viability of Plaintiffs’ “laws ... of the United States” argument rests entirely on their contention that this Court has the inherent authority to find that such a cause of action is implicit in the body of federal common law that incorporates the law of nations.
Plaintiffs are correct in their general assertion that federal courts have the authority to imply the existence of a private right of action for violations of jus cogens norms of international law. In Bivens v. Six Unknown Named Agents of the Fed. Bureau of Narcotics, 403 U.S. 388, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971) for example, the Supreme Court recognized there may be unique situations where private rights of action may be implied for violations of federal constitutional rights for which no statutory right of action exists, reasoning that “where federally protected rights have been invaded, it has been the rule from the beginning that courts will be alert to adjust their remedies so as to grant the necessary relief.” 403 U.S. 388, 392, 91 S.Ct. 1999, 29 L.Ed.2d 619 (1971) (quoting Bell v. Hood, 327 U.S. 678, 684, 66 S.Ct. 773, 90 L.Ed. 939 (1946)); see also United States v. Stanley, 483 U.S. 669, 710,
