BARRINGTON D. PARKER, Circuit Judge:

This consolidated appeal is from the judgments of the United States District Court for the Southern District of New York (Pauley, /.) dismissing two complaints for lack of subject matter jurisdiction under the Alien Tort Statute, 28 U.S.C. § 1350 (“ATS”), and in the alternative, on the ground of forum non conveniens. Plaintiffs-Appellants Rabi Abdullah! and other Nigerian children and their guardians sued Defendant-Appellee Pfizer, Inc. under the ATS (“the Abdullahi action”). They alleged that Pfizer violated a customary international law norm prohibiting involuntary medical experimentation on humans when it tested an experimental antibiotic on children in Nigeria, including themselves, without their consent or knowledge. Plaintiffs-Appellants Ajudu Ismaila Adamu and others, also children and their guardians who were part of Pfizer’s Nigerian drug experiment, brought a similar action against Pfizer, alleging violations of the ATS, the Connecticut Unfair Trade Practices Act (“CUTPA”), and the Connecticut Products Liability Act (“CPLA”) (“the Adamu action”). Pfizer moved to dismiss both actions for lack of subject matter jurisdiction *169and on the basis of forum non coveniens. The district court granted the motions and both sets of plaintiffs have appealed.

As explained below, we conclude: (1) that the district court incorrectly determined that the prohibition in customary international law against nonconsensual human medical experimentation cannot be enforced through the ATS; (2) that changed circumstances in Nigeria since the filing of this appeal require re-examination of the appropriate forum, albeit on the basis of a legal analysis different from that employed by the district court; and (3) that the district court incorrectly applied Connecticut’s choice of law rules in the Adamu action. Consequently, we reverse and remand the cases to the district court for further proceedings.

BACKGROUND

A. Pfizer’s Trovan Test in Nigeria

On review of a district court’s grant of a motion to dismiss, we assume as true the facts alleged in the complaints, construing them in the light most favorable to the appellants. See Vietnam Ass’n for Victims of Agent Orange v. Dow Chem. Co., 517 F.3d 104, 115 (2d Cir.2008). The central events at issue in these cases took place in 1996, during an epidemic of bacterial meningitis in northern Nigeria.1 The appellants allege that at that time, Pfizer, the world’s largest pharmaceutical corporation, sought to gain the approval of the U.S. Food and Drug Administration (“FDA”) for the use on children of its new antibiotic, Trovafloxacin Mesylate, marketed as “Trovan.” They contend that in April 1996, Pfizer, dispatched three of its American physicians to work with four Nigerian doctors to experiment with Trovan on children who were patients in Nigeria’s Infectious Disease Hospital (“IDH”) in Kano, Nigeria. Working in concert with Nigerian government officials, the team allegedly recruited two hundred sick children who sought treatment at the IDH and gave half of the children Trovan and the other half Ceftriaxone, an FDA-approved antibiotic the safety and efficacy of which was well-established. Appellants contend that Pfizer knew that Trovan had never previously been tested on children in the form being used and that animal tests showed that Trovan had life-threatening side effects, including joint disease, abnormal cartilage growth, liver damage, and a degenerative bone condition. Pfizer purportedly gave the children who were in the Ceftriaxone control group a deliberately low dose in order to misrepresent the effectiveness of Trovan in relation to Ceftriaxone. After approximately two weeks, Pfizer allegedly concluded the experiment and left without administering follow-up care. According to the appellants, the tests caused the deaths of eleven children, five of whom had taken Trovan and six of whom had taken the lowered dose of Ceftriaxone, and left many others blind, deaf, paralyzed, or brain-damaged.

Appellants claim that Pfizer, working in partnership with the Nigerian government, failed to secure the informed consent of either the children or their guardians and specifically failed to disclose or explain the experimental nature of the study or the serious risks involved. Although the treatment protocol required the researchers to offer or read the subjects documents requesting and facilitating their informed consent, this was allegedly not done in *170either English or the subjects’ native language of Hausa. The appellants also contend that Pfizer deviated from its treatment protocol by not alerting the children or their guardians to the side effects of Trovan or other risks of the experiment, not providing them with the option of choosing alternative treatment, and not informing them that the non-governmental organization MĂ©decins Sans FrontiĂ©res (Doctors Without Borders) was providing a conventional and effective treatment for bacterial meningitis, free of charge, at the same site.2

The appellants allege that, in an effort to rapidly secure FDA approval, Pfizer hastily assembled its test protocol at its research headquarters in Groton, Connecticut, and requested and received permission to proceed from the Nigerian government in March 1996. At the time, Pfizer also claimed to have secured approval from an IDH ethics committee. Appellants allege, however, that the March 1996 approval letter was backdated by Nigerian officials working at the government hospital well after the experiments had taken place and that at the time the letter was purportedly written, the IDH had no ethics committee.3 Appellants also contend that the experiments were condemned by doctors, including one on Pfizer’s staff at the time of the Kano trial.

In 1998, the FDA approved Trovan for use on adult patients only. After reports of liver failure in patients who took Trovan, its use in America was eventually restricted to adult emergency care. In 1999, the European Union banned its use.

B. The Proceedings Below

In August 2001, the Abdullahi plaintiffs sued Pfizer under the ATS, alleging that the experiments violated international law. In September 2002, the district court granted Pfizer’s motion to dismiss the Abdullahi claims on the ground oí forum non conveniens, conditioned on Pfizer’s consent to litigation in Nigeria. Abdullahi v. Pfizer, Inc., No. 01 Civ. 8118(WHP), 2002 WL 31082956, at *12 (S.D.N.Y. Sept. 17, 2002) (“Abdullahi I ”). It found that Nigeria was an adequate alternative forum despite plaintiffs’ contentions about corruption in the Nigerian court system. Id. at *8-10. The district court denied Pfizer’s motion to dismiss under Rule 12(b)(6), Fed.R.Civ.P., concluding that the plaintiffs adequately alleged that Pfizer’s collusion with the Nigerian government made it a state actor. Id. at *5-6.

Meanwhile, another group of children and guardians involved in the Trovan experiment sued in the Federal High Court in Kano, alleging claims under Nigerian law. That case, Zango v. Pfizer International, Inc., [2001] Suit No. FHC/ *171K/CS/204/2001 (Nigeria), was dismissed in 2003 after plaintiffs voluntarily discontinued the suit following the removal from the bench of the first judge assigned to the action and the second judge’s decision to decline jurisdiction for personal reasons. Abdullahi v. Pfizer, Inc., No. 01 Civ. 8118(WHP), 2005 WL 1870811, at *5 (S.D.N.Y. Aug. 9, 2005) (“Abdullahi III”). On appeal to this Court from the district court’s dismissal in Abdullahi I, the Abdullahi appellants argued that the dismissal of the Zango litigation was a result of rampant corruption, which indicated that the Nigerian judicial system could not provide an adequate alternative forum for their action. Given an inconclusive record regarding the events leading to the dismissal of the Zango lawsuit, we vacated the judgment and remanded for further fact-finding on forum,' non conveniens. See Abdullahi v. Pfizer, Inc., 77 Fed.Appx. 48, 53 (2d Cir.2003) (summary order) (“Abdullahi II ”).

In November 2002, following the dismissal of the Zango lawsuit, a number of the Zango plaintiffs filed the Adamu action. They alleged that in planning the Trovan experiment in Connecticut and in conducting the tests in Nigeria without informed,consent, Pfizer violated the CUT-PA, the CPLA, and the ATS. Eventually, the Adamu action was transferred to the Southern District of New York and consolidated with the Abdullahi action. Pfizer then moved to dismiss both cases for failure to state a claim under the ATS and on the basis of forum non conveniens. It also moved to dismiss in Adamu on the ground that Connecticut choice of law principles require the application of Nigerian law, which bars suit under CUTPA and the CPLA.

The district court granted the motions. See Abdullahi III, 2005 WL 1870811; Adamu v. Pfizer, Inc., 399 F.Supp.2d 495 (S.D.N.Y.2005). In Abdullahi III, Judge Pauley held that while “[pjlaintiffs correctly state that non-consensual medical experimentation violates the law of nations and, therefore, the laws of the United States,” they failed to identify a source of international law that “provide[s] a proper predicate for jurisdiction under the ATS.” 2005 WL 1870811, at *9, 14. Noting that “a decision to create a private right of action is one better left to legislative judgment in the great majority of cases,” he concluded that “[a] cause of action for Pfizer’s failure to get any consent, informed or otherwise, before performing medical experiments on the subject children would expand customary international law far beyond that contemplated by the ATS.” Id. at *13-14 (internal quotation marks omitted).

With regard to the forum non conveniens analysis, the district court declined to accept plaintiffs’ submissions concerning Pfizer’s alleged bribery of Nigerian officials on the ground that they were not based on personal knowledge. Id. at *16-17. Finding that the plaintiffs had failed to submit specific evidence that the Nigerian judiciary would be biased against its own citizens in an action against Pfizer, the district court alternatively held that Nigeria was an adequate alternate forum. Id. at *16,18.

Several months later, the district court also granted Pfizer’s motion to dismiss the Adamu case. Adamu, 399 F.Supp.2d 495. It relied on its Abdullahi III decision to hold that the plaintiffs could not establish jurisdiction under the ATS. Id. at 501. The district court also incorporated the forum non conveniens analysis from Abdullahi III to find that Nigeria is an adequate forum. Id. at 504. Applying the public and private interest factors set forth in Gulf Oil Corp. v. Gilbert, 330 U.S. 501, 508-09, 67 S.Ct. 839, 91 L.Ed. 1055 (1947), superseded by statute on other grounds as *172recognized in Cowan v. Ford Motor Co., 713 F.2d 100, 103 (5th Cir.1983), the court found that while public interest factors did not support either forum, private interest factors weighed in favor of dismissal. Adamu, 399 F.Supp.2d. at 505-06. The district court also dismissed the Adamu plaintiffs’ Connecticut law claims, concluding that, under Connecticut choice of law principles, the action was governed and barred by Nigerian law. Id. at 503.

The Abdullahi and Adamu plaintiffs appealed. Since then, a tectonic change has altered the relevant political landscape. In May 2007, the state of Kano brought criminal charges and civil claims against Pfizer, seeking over $2 billion in damages and restitution.4 Around the same time, the federal government of Nigeria sued Pfizer and several of its employees, seeking $7 billion in damages.5 None of these cases seek compensation for the subjects of the tests, who are the appellants before this Court. Pfizer then notified this Court that in light of these recent developments, which it believed required further consideration by the district court, it would not seek affirmance on the basis of forum non conveniens.

DISCUSSION

The district court dismissed both actions based on its determination that it lacked subject matter jurisdiction because plaintiffs failed to state claims under the ATS. We review dismissal on this ground de novo. Rweyemamu v. Cote, 520 F.3d 198, 201 (2d Cir.2008). “To survive dismissal, the plaintiff[s] must provide the grounds upon which [their] claim rests through factual allegations sufficient ‘to raise a right to relief above the speculative level.’ ” ATSI Commc’ns, Inc. v. Shaar Fund, Ltd., 493 F.3d 87, 98 (2d Cir.2007) (quoting Bell Atl. Corp. v. Twombly, 550 U.S. 544, 127 5. Ct. 1955, 1965, 167 L.Ed.2d 929 (2007)).6

I. The Alien Tort Statute

The Alien Tort Statute, 28 U.S.C. § 1350, provides that “[t]he district courts shall have original jurisdiction of any civil action by an alien for a tort only, committed in violation of the law of nations or a treaty of the United States.” Included in the Judiciary Act of 1789, the statute provided jurisdiction in just two cases during the first 191 years after its enactment. See Taveras v. Taveraz, 477 F.3d 767, 771 (6th Cir.2007). In the last thirty years, however, the ATS has functioned slightly more robustly, conferring jurisdiction over a limited category of claims.

We first extensively examined the ATS in Filartiga v. Pena-Irala, 630 F.2d 876 (2d Cir.1980), where we held that conduct violating the law of nations is actionable under the ATS “only where the nations of the world have demonstrated that the wrong is of mutual, and not merely several, concern, by means of express international accords.” Id. at 888. Following *173Filartiga, we concluded that ATS claims may sometimes be brought against private actors, and not only state officials, see Kadic v. Karadzic, 70 F.3d 232, 239 (2d Cir.1995), when the tortious activities violate norms of “universal concern” that are recognized to extend to the conduct of private parties — for example, slavery, genocide, and war crimes, id. at 240. This case involves allegations of both state and individual action. In Flores v. Southern Peru Copper Corp., 414 F.3d 233 (2d Cir.2003), we clarified that “the law of nations” in the ATS context “refers to the body of law known as customary international law,” which “is discerned from myriad decisions made in numerous and varied international and domestic arenas” and “does not stem from any single, definitive, readily-identifiable source.” Id. at 247-48. These principles are rejected in their entirety by our dissenting colleague. In Flores, we concluded that ATS jurisdiction is limited to alleged violations of “those clear and unambiguous rules by which States universally abide, or to which they accede, out of a sense of legal obligation and mutual concern.” Id. at 252. Applying this standard, we held that the appellants’ claim that pollution from mining operations caused lung disease failed to state a violation of customary international law. We reasoned that the “right to life” and the “right to health” were insufficiently definite to constitute binding customary legal norms and that there was insufficient evidence to establish the existence of a narrower norm prohibiting intranational pollution. Id. at 254-55.

In 2004, the Supreme Court comprehensively addressed the ATS for the first time in Sosa v. Alvarez-Machain, 542 U.S. 692, 124 S.Ct. 2739, 159 L.Ed.2d 718 (2004). Justice Souter, writing for the majority, clarified that the ATS was enacted to create jurisdiction over “a relatively modest set of actions alleging violations of the law of nations” and with “the understanding that the common law would provide a cause of action.” Id. at 720, 723. The Supreme Court confirmed that federal courts retain a limited power to “adapt[] the law of nations to private rights” by recognizing “a narrow class of international norms” to be judicially enforceable through our residual common law discretion to create causes of action. Id. at 728-29. It cautioned, however, that courts must exercise this power with restraint and “the understanding that the door [to actionable violations] is still ajar subject to vigilant doorkeeping,” permitting only those claims that “rest on a norm of international character accepted by the civilized world and defined with a specificity comparable to the features of the 18th-century paradigms [the Supreme Court has] recognized.” Id. at 725, 729. These 18th-centu-ry paradigms consist of offenses against ambassadors, violations of the right to safe passage, and individual actions arising out of piracy. Id. at 724. The common theme among these offenses is that they contravened the law of nations, admitted of a judicial remedy, and simultaneously threatened serious consequences in international affairs. Id. at 715. Lower courts are required to gauge claims brought under the ATS against the current state of international law, but are permitted to recognize under federal common law only those private claims for violations of customary international law norms that reflect the same degree of “definite content and acceptance among civilized nations” as those reflected in the 18th-century paradigms. Id. at 732-33. The Supreme Court in Sosa also counseled that “the determination whether a norm is sufficiently definite to support a cause of action should (and, indeed, inevitably must) involve an element of judgment about the practical consequences of making that *174cause available to litigants” in federal courts. Id.

In this way Sosa set a “high bar to new private causes of action” alleging violations of customary international law. Id. at 727. A federal court can recognize one only if a plaintiff identifies the violation of a norm of customary international law that, as defined by the sources of such law that United States courts “have long, albeit cautiously, recognized,” id. at 733-34 (referencing The Paquete Habana, 175 U.S. 677, 700, 20 S.Ct. 290, 44 L.Ed. 320 (1900)), is sufficiently specific, universal, and obligatory to meet the standards established by Sosa. See Sosa, 542 U.S. at 732, 124 S.Ct. 2739 (citing with approval Tel-Oren v. Libyan Arab Republic, 726 F.2d 774, 781 (D.C.Cir.1984) (Edwards, J., concurring), and In re Estate of Marcos, Human Rights Litig., 25 F.3d 1467, 1475 (9th Cir.1994)). Applying these principles, the Supreme Court held that the plaintiff, a Mexican national who sued a fellow Mexican national under the ATS for allegedly aiding in his illegal abduction by agents of the U.S. Drug Enforcement Agency, had failed to allege the violation of a customary international law norm with the required precision. Sosa, 542 U.S. at 738, 124 S.Ct. 2739. The Supreme Court found that the practical consequences of recognizing a general and broad customary international law prohibition of arbitrary detention in a case involving “a single illegal detention of less than a day, followed by the transfer of custody to lawful authorities and a prompt arraignment” would be “breathtaking” and inappropriate. Id. at 736, 738, 124 S.Ct. 2739.

Since Sosa, this Court has reviewed three judgments dismissing claims under the ATS. In Khulumani v. Barclay National Bank, Ltd., 504 F.3d 254 (2d Cir.2007) (per curiam), we held that the ATS conferred jurisdiction over multinational corporations that purportedly collaborated with the government of South Africa in maintaining apartheid because they aided and abetted violations of customary international law. Id. at 260. In Vietnam Ass’n for Victims of Agent Orange v. Dow Chemical Co., 517 F.3d 104 (2d Cir.2008), we concluded that the ATS did not support a claim that the defendants violated international law by manufacturing and supplying Agent Orange and other herbicides used by the United States military during the Vietnam War. Id. at 123. We reasoned that the sources of law on which the appellants relied did not define a norm prohibiting the wartime use of Agent Orange that was both universal and sufficiently specific to satisfy the requirements of Sosa. Id. at 119-23. Similarly, in Mora v. People of the State of New York, 524 F.3d 183 (2d Cir.2008), we held that the norm at issue — one that prohibits the detention of a foreign national without informing him of the requirement of consular notification and access under Article 36(1)(b)(3) of the Vienna Convention on Consular Relations — was insufficiently universal to support a claim under the ATS. Id. at 208-09.

Turning now to this appeal, and remaining mindful of our obligation to proceed cautiously and self-consciously in this area, we determine whether the norm alleged (1) is a norm of international character that States universally abide by, or accede to, out of a sense of legal obligation; (2) is defined with a specificity comparable to the 18th-century paradigms discussed in Sosa; and (3) is of mutual concern to States.

A The Prohibition of Nonconsensual Medical Experimentation on Humans

Appellants’ ATS claims are premised on the existence of a norm of custom*175ary international law prohibiting medical experimentation on non-consenting human subjects. To determine whether this prohibition constitutes a universally accepted norm of customary international law, we examine the current state of international law by consulting the sources identified by Article 38 of the Statute of the International Court of Justice (“ICJ Statute”), to which the United States and all members of the United Nations are parties. Flores, 414 F.3d at 250; see, e.g., United States v. Yousef, 327 F.3d 56, 100-01 (2d Cir.2003). Article 38 identifies the authorities that provide “competent proof of the content of customary international law.” Flores, 414 F.3d at 251. These sources consist of:

(a) international conventions, whether general or particular, establishing rules expressly recognized by the contesting states;
(b) international custom, as evidence of a general practice accepted as law;
(c) the general principles of law recognized by civilized nations;
(d) ... judicial decisions and the teachings of the most highly qualified publicists of the various nations, as subsidiary means for the determination of rules of law.

Statute of the International Court of Justice, art. 38(1), June 26,1945, 59 Stat. 1055, 1060, T.S. No. 993 [hereinafter ICJ Statute].

The appellants ground their claims in four sources of international law that categorically forbid medical experimentation on non-consenting human subjects: (1) the Nuremberg Code, which states as its first principle that “[t]he voluntary consent of the human subject is absolutely essential”; (2) the World Medical Association’s Declaration of Helsinki, which sets forth ethical principles to guide physicians world-wide and provides that human subjects should be volunteers and grant their informed consent to participate in research; (3) the guidelines authored by the Council for International Organizations of Medical Services (“CIOMS”), which require “the voluntary informed consent of [a] prospective subject”; and (4) Article 7 of the International Covenant on Civil and Political Rights (“ICCPR”), which provides that “no one shall be subjected without his free consent to medical or scientific experimentation.” 7

The district court found that “non-consensual medical experimentation violates the law of nations and, therefore, the laws of the United States” and cited the Nuremberg Code for support. Abdullahi III, 2005 WL 1870811, at *9. It then noted that “[w]hile federal courts have the authority to imply the existence of a private right of action for violations of jus cogens norms of international law, federal courts must consider whether there exist special factors counseling hesitation in the absence of affirmative action by Congress.” Id. (internal citations and quotation marks omitted). The district court then separately analyzed the four sources of international law that prohibit nonconsensual medical experimen*176tation on humans and the Universal Declaration of Human Rights. Id. at *11-13. It found that with the exception of the Nuremberg Code, these sources contain only aspirational or vague language lacking the specificity required for jurisdiction. Id. at *12-13. It also determined that because the United States did not ratify or adopt any of these authorities except the ICCPR, and because even the ICCPR is not self-executing, none of them create binding international legal obligations that are enforceable in federal court. Id. at *11-13. Finally, the district court concluded that the plaintiffs failed to provide a proper predicate for ATS jurisdiction because none of the sources independently authorizes a private cause of action and the inference of such a cause of action is a matter best left to Congress. Id. at *13-14.8

The district court’s approach misconstrued both the nature of customary international law and the scope of the inquiry required by Sosa. It mistakenly assumed that the question of whether a particular customary international law norm is sufficiently specific, universal, and obligatory to permit the recognition of a cause of action under the ATS is resolved essentially by looking at two things: whether each source of law referencing the norm is binding and whether each source expressly authorizes a cause of action to enforce the norm. But Sosa, as we have seen, requires a more fulsome and nuanced inquiry. Courts are obligated to examine how the specificity of the norm compares with 18th-century paradigms, whether the norm is accepted in the world community, and whether States universally abide by the norm out of a sense of mutual concern. By eschewing this inquiry, the district court did not engage the fact that norms of customary international law are “discerned from myriad decisions made in numerous and varied international and domestic arenas” and “[do] not stem from any single, definitive, readily-identifiable source.” Flores, 414 F.3d at 247-48.

The district court also inappropriately narrowed its inquiry in two respects. First, it focused its consideration on whether the norm identified by the plaintiffs is set forth in conventions to which the United States is a party, and if so, whether these treaties are self-executing or executed by federal legislation. While adoption of a self-executing treaty or the execution of a treaty that is not self-executing may provide the best evidence of a particular country’s custom or practice of recognizing a norm, see Flores, 414 F.3d at 257, the existence of a norm of customary international law is one determined, in part, by reference to the custom or practices of many States, and the broad acceptance of that norm by the international community. Agreements that are not self-executing or that have not been executed by federal legislation, including the ICCPR, are appropriately considered evidence of the current state of customary international law. See Khulumani, 504 F.3d at 284 (Katzmann, J., concurring) (noting that “[w]hether a treaty that embodies [a norm of customary international law] is self-executing is relevant to, but is not determinative of, [the] question” of whether the norm permits ATS jurisdiction). A formal treaty, moreover, is not the lone primary source of customary international law. The ICJ Statute permits, and Sosa encourages, among other things, that courts consider “international custom, as evidence of a general practice accepted *177as law.” ICJ Statute, supra, at art. 38(1); Sosa, 542 U.S. at 734, 124 S.Ct. 2739 (“[WJhere there is no treaty, and no controlling executive or legislative act or judicial decision, resort must be had to the customs and usages of civilized nations.”) (quoting The Paquete Habana, 175 U.S. at 700, 20 S.Ct. 290).

Second, the district court’s consideration of whether each source of law creates binding legal norms failed to credit the fact that even declarations of international norms that are not in and of themselves binding may, with time and in conjunction with state practice, provide evidence that a norm has developed the specificity, universality, and obligatory nature required for ATS jurisdiction. See Filartiga, 630 F.2d at 883 (“[A non-binding] Declaration creates an expectation of adherence, and insofar as the expectation is gradually justified by State practice, a declaration may by custom become recognized as laying down rules binding upon the States.”) (internal quotation marks omitted). The district court should have considered a greater range of evidence and weighed differently the probative value of the sources on which the appellants relied.

In sum, it was inappropriate for the district court to forego a more extensive examination of whether treaties, international agreements, or State practice have ripened the prohibition of nonconsensual medical experimentation on human subjects into a customary international law norm that is sufficiently (i) universal and obligatory, (ii) specific and definable, and (iii) of mutual concern, to permit courts to infer a cause of action under the ATS. See Sosa, 542 U.S. at 732-35, 124 S.Ct. 2739. We now proceed with such an examination.

i. Universality

The appellants must allege the violation of a norm of customary international law to which States universally subscribe. See Sosa, 542 U.S. at 732, 124 S.Ct. 2739; Vietnam Ass’n for Victims of Agent Orange, 517 F.3d at 117. The prohibition on nonconsensual medical experimentation on human beings meets this standard because, among other reasons, it is specific, focused and accepted by nations around the world without significant exception.

The evolution of the prohibition into a norm of customary international law began with the war crimes trials at Nuremberg. The United States, the Soviet Union, the United Kingdom and France “acting in the interest of all the United Nations,” established the International Military Tribunal (“IMT”) through entry into the London Agreement of August 8, 1945. M. Cheriff Bassiouni et al., An Appraisal of Human Experimentation in International Law and Practice: The Need for International Regulation of Human Experimentation, 72 J.Crim. L. & Criminology 1597, 1640 & n. 220 (1981) (internal quotation marks omitted). Annexed to the London Agreement was the London Charter, which served as the IMT’s Constitution. See Agreement for the Prosecution and Punishment of the Major War Criminals of the European Axis Powers, with annexed Charter of the International Military Tribunal art. 2, Aug. 8, 1945, 59 Stat. 1544, 82 U.N.T.S. 279. According to the Charter, the IMT had the “power to try and punish persons who, acting in the interests of the European Axis countries, whether as individuals or as members of organizations, committed,” among other offenses, war crimes and crimes against humanity. Id. at art. 6.

The IMT tried 22 “major” Nazi war criminals leaving “lower-level” war criminals, including “[l]eading physicians ... and leading German industrialists,” to be tried in subsequent trials by U.S. military tribunals acting “under the aegis of the *178IMT.” United States Holocaust Memorial Museum, War Crimes Trials, Holocaust Encylopedia (2008), http://www.ushmm. org/wlc/article.php?lang=en&ModuleId= 10005140. The law that authorized the creation of the U.S. military tribunals, Control Council Law No. 10, was enacted in 1945 by the Allied Control Council, see id., an authority through which the London Agreement signatories exerted joint-control over Germany, see Encyclopedia Britannica, Germany, Encyclopedia Britannica Online (2009), http://search.eb.com/ eb/article-58214. Control Council Law No. 10 stated that its purpose was to “give effect to the terms of ... the London Agreement ... and the [Lond
