MEMORANDUM OPINION BATES, District Judge. “The writ of habeas corpus commands general recognition as the essential remedy to safeguard a citizen against imprisonment by State or Nation in violation of his constitutional rights.” United States v. Morgan, 346 U.S. 502, 506 n. 3, 74 S.Ct. 247, 98 L.Ed. 248 (1954) (quotation omitted). This case requires the Court to give substance to those words. Petitioner Ahmed Abu Ali (“Abu Ali”) is a citizen of the United States who, through his parents, has filed a petition for a writ of habeas corpus against several officials of the United States (“respondents” or “United States”) challenging his ongoing detention since June 2003 in a prison of the Kingdom of Saudi Arabia allegedly at the behest and ongoing supervision of the United States. Petitioners have provided evidence, of varying degrees of competence and persuasiveness, that: (i) the United States initiated the arrest of Abu Ali in Saudi Arabia; (ii) the United States has interrogated Abu Ali in the Saudi prison; (iii) the United States is controlling his detention in Saudi Arabia; (iv) the United States is keeping Abu Ali in Saudi Arabia to avoid constitutional scrutiny by United States courts; (v) Saudi Arabia would immediately release Abu Ali to United States officials upon a request by the United States government; and (vi) Abu Ali has been subjected to torture while in the Saudi prison. The United States does not offer any facts in rebuttal. Instead, it insists that a federal district court has no jurisdiction to consider the habeas petition of a United States citizen if he is in the hands of a foreign state, and it asks this Court to dismiss the petition forthwith. The position advanced by the United States is sweeping. The authority sought would permit the executive, at his discretion, to deliver a United States citizen to a foreign country to avoid constitutional scrutiny, or, as is alleged and to some degree substantiated here, work through the intermediary of a foreign country to detain a United States citizen abroad. The Court concludes that a citizen cannot be so easily separated from his constitutional rights. Earlier this year, the Supreme Court confirmed the fundamental right of a citizen to be free from involuntary, indefinite confinement by his government without due process. See Hamdi v. Rumsfeld, — U.S. -, -, 124 S.Ct. 2638, 2647, 159 L.Ed.2d 578 (2004); id. at 2661 (Scalia, J., dissenting); see also Rasul v. Bush, — U.S. -, -, 124 S.Ct. 2686, 2692, 159 L.Ed.2d 548 (2004). Abu Ali was not captured on a battlefield or in a zone of hostilities — rather, he was arrested in a university classroom while taking an exam. The United States has therefore not invoked the executive’s war powers as a rationale for his detention — instead, the United States relies on the executive’s broad authority to conduct the foreign affairs of the country as a basis to insulate Abu Ali’s detention from judicial scrutiny. There are, to be sure, considerable and delicate principles of separation of powers that dictate caution and will narrow the inquiry in this case. Such principles, however, have never been read to extinguish the fundamental due process rights of a citizen of the United States to freedom from arbitrary detention at the will of the executive, and to access to the courts through the Great Writ of habeas corpus to challenge the legality of that detention. The present posture of this case requires this Court to accept petitioners’ well-supported allegations, to which the United States has not responded. The United States’ broad assertion of authority, and corresponding contention that this Court lacks jurisdiction, cannot withstand petitioners’ assertions at this time. The Court will accordingly authorize expeditious jurisdictional discovery in this matter to further explore those contentions. The process of defining the scope of that discovery is set out in the accompanying order. In the meantime, the request of the United States to dismiss the petition for lack of habeas corpus jurisdiction will be denied. BACKGROUND I. The Arrest of Abu Ali Petitioner Ahmed Abu Ali (“Abu Ali”) is an American citizen who was born in Houston, Texas. See Petition ¶ 25; id. Ex. A (Birth Certifícate). After graduating as valedictorian of his high school class in Virginia, he enrolled as a scholarship student at the Islamic University of Medina in Saudi Arabia. See Petition ¶¶ 26-27. On June 11, 2003, while he was taking his final exam at the university, Saudi security officers entered his classroom and arrested him. Since that day, Abu Ali has been detained indefinitely in a Saudi prison without charge or access to counsel. See Petition ¶¶ 26-28. At about the same time that Abu Ali was arrested, three other Americans in Saudi Arabia were also apprehended by Saudi officials. See id. ¶ 29. Unlike Abu Ali, each of these individuals was extradited a month later to the United States. See id. Once in the United States, they were charged, along with eight other Northern Virginia men, with undertaking paramilitary training to wage a terrorist jihad on behalf of Muslims. See United States v. Royer, Crim. No. 03-296-A (E.D.Va.). Abu Ali thus was the only American citizen not extradited to the United States and charged with a crime. FBI agents raided Abu Ali’s home in Virginia on June 16, 2003, less than a week after he was arrested in Saudi Arabia. The search warrant was issued by the United States District Court for the Eastern District of Virginia (the same court in which the Royer proceedings were located), and instructed the agents to look for weapons, cellular phones, and documents tending to show a conspiracy between Abu Ali and four of the defendants in the Royer case. See Petition ¶ 31; id. Ex. B (Search Warrant). Some time later, a prosecutor in the Royer proceedings would acknowledge that the search of Abu Ali’s home was conducted “in connection with” the Royer prosecution. See Petition ¶ 32; Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 10. Roughly five days after Abu Ali was arrested, and at about the same time as the raid on his home took place, FBI agents visited the Saudi prison in which Abu Ali was detained and watched as he was interrogated by Saudi officials. See Petition ¶ 32; Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 5. The prosecutor in the Royer case has acknowledged that this interrogation took place. Id. The prosecutor says that during the interrogation Abu Ali confessed to joining a “clandestine al Qaeda cell” and admitted that “al Qaeda told him he must either conduct terrorist operations or return to the United States and establish an al Qaeda cell.” Id. II. The Months Following the Detention Abu Ali’s parents, also petitioners in this matter, assert that Abu Ali was held incommunicado for at least a month after his arrest. See Petition ¶ 33. They claim that they sought assistance from the State Department, but their requests were initially ignored. See Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 7. Later, they say, the State Department told them that Saudi Arabia did not permit the United States Embassy to have access in the first month of his detention, and that the Saudis had failed to respond at all to several diplomatic notes regarding Abu Ali. See id. Abu Ali’s parents took their concerns to a newspaper reporter who had been covering the Royer prosecution. In a July 2003 article, that reporter quoted a Saudi Embassy spokesman as saying that the United States Legal Attache office — the name for the FBI overseas station — “had full and complete and direct access” to Abu Ali from the moment of his arrest. The Saudi official explained: “For us, it was a representative of the U.S. So the U.S. Embassy had full access, as far as we were concerned.” Id. At about this time, Abu Ali’s parents say they threatened to sue the State Department for failing to secure the safety of a United States citizen. They claim that, in response, Matthew Gillen, the Director of U.S. Consular Affairs in Saudi Arabia, met with Abu Ali in the Saudi prison in early July. Abu Ali’s parents also received the first of several phone calls from their son on July 31, 2003. See id. From that point on, they would maintain intermittent contact with Abu Ali through reports from consul visits and occasional phone conversations. In September 2003, several FBI agents traveled to Saudi Arabia and interrogated Abu Ali for at least four days. See Petition ¶ 36; Afi. of Faten Abu Ali, Aug. 18, 2004, ¶ 1. According to an affidavit from Abu Ali’s mother, Abu Ali told her in a phone call that the FBI agents had threatened to declare him an enemy combatant and send him to Guantanamo Bay, Cuba, if he did not cooperate. See Mi. of Faten Abu Ah, Aug. 13, 2004, ¶ 1. Consul Gillen would later tell the family that Abu Ali had also told him about this threat during one of his consul visits to the prison. See Petition ¶ 36; Aff. of Omar Abu Ali, Aug. 13, 2004, ¶ 1. Abu Ali’s mother also says that Abu Ali told her the FBI agents threatened to put him on trial in Saudi Arabia without counsel. See Aff. of Faten Abu Ali, Aug. 18, 2004, ¶ 1. Abu Ali’s father, who works as a system analyst at the Royal Embassy of Saudi Arabia in Washington, D.C., prevailed on his contacts in the Saudi government to assist him in his search for information regarding the detention of his son. See Afi. of Omar Abu Ali, Sept. 20, 2004, ¶ 1. He claims that unidentified officials in the Saudi Embassy “consistently told me that Ahmed has not violated Saudi laws, and that there are no plans to prosecute him in Saudi Arabia.” Afi. of Omar Abu Ali, Sept. 20, 2004, ¶ 2. He also says that he spoke “to several high-ranking officials at the Saudi Embassy who are familiar with Ahmed’s case, and whom I am unable to name for security and privacy concerns.” Id. He claims that they “have described Ahmed’s arrest and detention as an ‘American case’ that Saudi Arabia has no control over due to strong political pressure from the U.S. government to keep Ahmed in Saudi custody.” Id. ¶ 2. Petitioners allege that they were receiving other indications at the time as well that the United States was behind the detention of their son. Abu Ali’s father asserts that in September 2003 he asked a high-ranking government official in Saudi Arabia to visit his son in order to check on his safety. The official returned with the information that he “was instructed to ‘stay away’ because the U.S. was behind the case.” Id. ¶ 3. Abu Ali’s parents also describe a November 2003 phone call in which Abu Ali told them that Consul Charles Glatz of the United States Embassy in Saudi Arabia had informed him that his case was in the hands of Washington, not the Saudi government. See Afi. of Faten Abu Ali, August 13, 2004, ¶ 2. Petitioners claim that Consul Glatz told Abu Ali (who then told them) that he had received this information from the FBI. See id. III. The Royer Proceedings Meanwhile, the Royer prosecution was proceeding forward in the United States. In a hearing on a motion to suppress certain statements that he had made while being questioned in Saudi Arabia, Sabri Benkhala- — one of the three Americans who had been arrested in Saudi Arabia and then extradited — testified that Saudi officials, while interrogating him, had shown him pictures of people who appeared to have been physically tortured. See Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 9. Benkhala also testified that when he was visited for the first time by a U.S. Consul in the Saudi prison, the consul told Benkhala that he had been arrested at the request of the FBI. See id. Finally, according to Benkhala, a Saudi General who was present at his meeting with the U.S. Consul officer apologized to him after-wards and told him “you have not broken any laws in Saudi Arabia, and we know you’re a good person ... we were requested by the FBI to arrest you.” The presiding judge in Royer concluded that the statements Benkhala had made during the Saudi interrogation were coerced and excluded them from trial. See Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 9. Six of the defendants in the Royer proceedings entered pleas, three were convicted at trial, and two were acquitted (one of the acquittals was Benkhala). Abu Ali’s father states in an affidavit that members of the FBI and the U.S. Attorney’s Office told his former attorney, Martin McMahon, that a grand jury had considered the case against Abu Ali and had found no evidence to indict him. See Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 10. Abu All’s father also says that Mends and family members who were called as witnesses by the grand jury have confirmed that the grand jury deliberated from July 2003 through the first few months of 2004. See id. Petitioners state that in May 2004 they reached an agreement with the prosecutor leading the Royer investigation through which Abu Ali would be released in exchange for a final “exit interview” at which counsel would be present for Abu Ali. Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 9. Petitioners say that their then-counsel sent a letter to the U.S. Ambassador in Saudi Arabia requesting his intervention in securing the arrangement. Id. For reasons that are unclear from the record, this arrangement fell through. Nevertheless, Abu Ali’s mother avers that in a May 20, 2004, meeting between the FBI and her now ex-counsel, Stanley Cohen, the FBI told Cohen that they would release Abu Ali if he revoked his U.S. citizenship and lived in another country. See Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 6. At the same time, petitioners claim that the Washington Field Office of the FBI began stating publicly that the office had no further interest in Abu Ali’s detention. Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 9. The Assistant Director in charge of the FBI Washington Field Office is quoted in a June 18, 2004, Washington Post article as saying that he doesn’t “speak for the entire U.S. government,” but that when he asked agents in his office whether they have a “continuing interest in this individual ... the answer I got was no.” He also said that he thought Abu Ali was “within a week of being released” in early May 2004. Caryle Murphy, Protest ers Seek Release of Saiidi Prisoner, Washington Post, June 18, 2004, at B3. IV. The May 14, 2004, Meeting with Consul Gillen Petitioners, accompanied by their then-counsel Ashraf Nubani, and the Executive Director and the Governmental Relations Coordinator of the Council on American Islamic Relations, met with Consul Gillen on May 14, 2004. See Aff. of Faten Abu Ali, Aug. 13, 2004, ¶ 3; Aff. of Faten Abu Ali, Sept. 20, 2004, ¶ 1; Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 15. Consul Gillen showed petitioners two documents: a May 10, 2004, email from Consul Glatz to Consul Gillen, and an undated cable from the United States Embassy in Riyadh to the State Department. See Aff. of Faten Abu Ali, Aug. 13, 2004, ¶ 3; Aff. of Faten Abu Ali, Sept. 20, 2004, ¶ 1. Petitioners attest that Consul Gillen refused to give them copies of the documents, but allowed them to copy the documents manually. See Aff. of Faten Abu Ali, Aug. 13, 2004, ¶ 3; Aff. of Faten Abu Ah, Sept. 20, 2004, ¶ 1. Abu Ali’s mother has submitted an affidavit in which she transcribes the contents of these documents. See Aff. of Faten Abu Ah, Sept. 20, 2004. As reproduced by Abu Alfs mother, the email from Consul Glatz to Consul Gillen states that Abu Ah declined to see Glatz during his most recent consul visit, and that the Saudi Colonel who is the prison director refused to take him into the cell block to see Abu Ah. See Aff. of Faten Abu Ah, Sept. 20, 2004, 1ila. The cable continues: “The colonol said that he understood that we could have him rendered to the U.S. at anytime. He added that Abu Ali is saying that he would not voluntarily go back to the U.S., but was interested in going to Sweden.” Id. As transcribed by Abu Ali’s mother, the cable states: SBU Col Al-Qahtani commented to Co-noff [consular officer] that he understood that Abu-Ali could be rendered to American authorities at any time if the USG [US Government] made a formal request. He added that he understood that if Abu-Ali were deported from Saudi Arabia he would not want to return to the U.S. but has been thinking of traveling to Sweden. • Aff. of Faten Abu Ali, Sept. 20, 2004, ¶ lb. Petitioners state that Consul Gillen told them at the meeting that “there were no charges against [Abu Ali] and no current investigation of him.” Aff. of Faten Abu Ali, Aug. 13, 2004, ¶ 3. According to petitioners, Consul Gillen also told them that he would personally send a formal request for Ahmed’s release. Aff. of Faten Abu Ali, Aug. 13, 2004, ¶ 3; Aff. of Omar Abu Ali, Aug. 13, 2004, ¶ 6. A month later, however, in a meeting attended by Abu Ali’s father and Gillen, petitioners say that Gillen explained that he would be unable to send the letter because there was an ongoing investigating of Abu Ali in the United States Department of Justice. Aff. of Omar Abu Ali, Aug. 13, 2004, ¶ 6. Abu Ali’s family appealed to their political representatives for assistance. On July 21, 2004, Congressman David Woo’s office wrote to Abu Ali’s uncle that the State Department “has indicated that they are prepared to take action on Ahmed’s behalf once he receives final clearance” from the Department of Justice. Likewise, in a June 2, 2004, meeting, Ann Rust, Department of Constituent Services from Congressman Tom Davis’s office, informed Abu Ali’s parents that the State Department had told her that Abu Ali’s release would take place “once all government agencies were no longer interested in him.” Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 14. In the meantime, Abu Ali’s parents continued pressing their connections with Saudi officials. Abu Ali’s father attests that in May 2004, an official at the Saudi embassy told him that if he ever wanted his son to come back home, he should pressure U.S. officials to request his release. Aff. of Omar Abu Ali, Sept. 20, 2004, ¶ 3. V. Allegations of Torture Petitioners relate their growing concern that Abu Ali has been subjected to torture during his detention in Saudi Arabia. They maintain that they have received information from an unidentified eyewitness in Saudi Arabia who said that he saw Abu Ali experiencing so much pain in his hands that he was unable to pick up a pen to sign documents. Aff. of Faten Abu Ali, Aug. 18, 2004, ¶ 2. At the same time, petitioners cite two instances where the Assistant U.S. Attorney leading the Royer prosecution has allegedly made comments indicating that Abu Ali has had his fingernails removed. Aff. of Faten Abu Ali, Sept. 17, 2004, ¶¶ 3, 6. The first of these instances was allegedly in a meeting between the Assistant U.S. Attorney and the defendants in the Royer prosecution. According to petitioners, Sei-fullah Chapman, one of the defendants, reported to them in August 2004 that the prosecutor had said that Abu Ali “doesn’t have to worry about clipping his fingernails anymore.” Aff. of Faten Abu Ali, Sept. 17, 2004, ¶ 3. Salim Ali, a lawyer for one of the Royer defendants, describes in an affidavit a conversation that he claims he had with the same prosecutor while they were waiting at a courthouse in June 2003 after a hearing in the Royer case. Salim Ali says that he asked the prosecutor whether Abu Ali should be returned to the United States to face charges. He explains that the prosecutor “smirked and stated that ‘he’s no good for us here, he has no fingernails left.” ’ Aff. of Salim Ali, Oct. 12, 2004, ¶ 6. In a September 2004 phone call with Abu Ali, his parents mentioned the prosecutor’s comments, to which Abu Ali replied, “there are hidden things which you don’t know about that are even worse.” Aff. of Fa-tim Abu Ali, Sept. 17, 2004, ¶ 6. Petitioners also provide an affidavit from a specialist for Saudi Arabia from Amnesty International USA who testifies that Abu Ali is at a serious risk of torture while he remains detained in Saudi Arabia. He describes many instances of torture recounted by Westerners who have been arrested in Saudi Arabia, and notes that the U.S. Department of State itself describes “credible reports” that Saudi authorities have “abused detainees, both citizens and foreigners.” Aff. of Brian Evans, Sept. 17, 2004, at 1-2. VI. The Proceedings in this Action On July 28, 2004, Abu Ali’s parents filed in this Court a petition for a writ of habeas corpus on behalf of their son. The petition challenges his detention under the United States Constitution and other sources of domestic and international law, and names as respondents the Attorney General of the United States, the Director of the FBI, and several other United States officials (“respondents” or “United States”). The petition seeks a variety of different forms of relief, but the essence of the request is that the Court determine whether Abu Ah’s rights are being violated by his detention in a Saudi prison and, if they are, issue a writ requiring the United States to release Abu Ali, or obtain his release, and bring him before the Court for further proceedings. See Petition at 24-25. A few hours after filing the petition, Abu Ali’s parents claim to have received a call from an official at the State Department saying that the United States had been informed by the Saudi government that they were planning shortly to bring charges against Abu Ali. See Mot. Prelim. Inj. at 1. Within a week of that call, petitioners filed a motion for a preliminary injunction or a temporary restraining order asking this Court to instruct the United States government to refrain from pressuring the Saudi government to bring charges against Abu Ali. The United States responded with declarations from the State Department official who placed the call to petitioners and from the Deputy Assistant Director of Operations in the Counterterrorism Division of the FBI, stating that Saudi authorities had told the FBI as early as July 18, 2004- — more than a week before petitioners filed this action — that they intended to bring criminal charges against Abu Ali. According to the declarations, this information was forwarded to the State Department in a cable from the U.S. embassy in Riyadh dated July 26, 2004, and Abu Ali’s parents were informed two days later. See Decl. of Leigh Rieder ¶¶ 2-4; Decl. of Willie T. Hulon ¶ 2. This Court denied petitioners’ motion for a preliminary injunction. See Mem. Op. & Order, dated Aug. 31, 2004. The Court explained that the jurisdictional basis for the habeas petition was uncertain, id. at 5-10, and that the particular relief petitioners sought in their motion — an order instructing the United States government to refrain from communicating anything to the Saudi government that would lead the Saudi government to press charges against Abu Ali — was problematic, id. at 11-14. Such an order would have entangled the judiciary in the diplomatic communications between the United States and an ally on the one hand, and would not have remedied any discernible irreparable harm to Abu Ali on the other, inasmuch as even complete silence by the United States would have left the Saudi government free to continue to detain and interrogate Abu Ali, and even to press charges if they wished. See id. Some time earlier, the Court had issued an order requiring the United States to show cause why the petition for a writ of habeas corpus should not be granted. In response, the United States filed papers in which it asks the Court to dismiss the habeas petition as a matter of law. The United States does not offer any evidence (or even contentions) rebutting petitioners’ claims regarding its role in the detention of their son. Instead, the United States seeks dismissal on the theory that a federal court lacks jurisdiction to issue a writ of habeas corpus where the prisoner is currently being held by a foreign custodian, no matter what role the United States allegedly has played in his detention. See Resp’ts’ Supplemental Filing at 1-2. In response, petitioners submitted additional legal arguments and affidavits to support the legal claims advanced and relief sought in their habeas petition. The government’s request to dismiss the petition is now fully briefed and ready for decision by the Court. To the Court’s knowledge, the Saudi government has not brought any charges against Abu Ali. VII. Summary of Factual Allegations At this time and juncture, then, the facts before this Court consist essentially of petitioners’ allegations, supported by several affidavits and other materials. In brief, those well-supported factual allegations paint the following picture. This is merely a recitation of the allegations and reasonable inferences that the Court must at this stage in the proceedings take as true; the Court is not at this time finding the allegations to be true. Abu Ali is a citizen of the United States who was born and raised in this country. He was arrested by Saudi officials while taking an examination at the university he was attending in Saudi Arabia. The United States orchestrated the detention and was intimately involved from the very beginning. FBI agents attended his interrogation by Saudi officials mere days after his arrest; FBI agents raided his parents’ home in Virginia at roughly the same time; and three other United States citizens living in Saudi Arabia were arrested almost simultaneous with Abu Ali and extradited to the United States to stand trial, where one of them testified that he was told by United States and Saudi officials that he was arrested at the behest of the United States. Abu Ali has said that he was told the same thing by an official from the United States Embassy. Saudi officials have described the detention privately as a United States matter, have acknowledged publicly that the United States has been involved throughout his detention, and have told United States officials that they would release Abu Ali at the request of the United States. FBI agents have interrogated Abu Ali at length in the Saudi prison. United States officials have also indicated to Abu Ali and to his parents on several occasions that they could release him if he cooperated or, if he did not, either keep him in the Saudi prison where he would be tried without counsel or send him to Guantanamo Bay where he would be detained as an “enemy combatant.” More recently, officials from the State Department and from the United States Embassy in Saudi Arabia have indicated to Abu Ali’s parents and to others that Abu Ali would be released as soon as the Department of Justice completed its investigation of him. An agreement between Abu Ali’s parents and the United States on the terms of Abu Ali’s release was nearly reached on more than one occasion, but it has fallen through each time. According to petitioners, the United States has chosen to keep Abu Ali in Saudi Arabia because a grand jury refused to return an indictment against Abu Ali in the United States, and because United States officials want to continue to obtain information from him in a context that is free of constitutional scrutiny. There is at least some circumstantial evidence that Abu Ali has been tortured during interrogations with the knowledge of the United States. FBI agents have despaired at his continued detention and more than one United States official has stated that Abu Ali is no longer a threat to the United States and there is no active interrogation. Nonetheless, he has been held indefinitely without charge, explanation for his detention, or access to counsel since the time of his arrest in June 2003. ANALYSIS There is no principle more sacred to the jurisprudence of our country or more essential to the liberty of its citizens than the right to be free from arbitrary and indefinite detention at the whim of the executive. As recently as this year, the Supreme Court reaffirmed “the fundamental nature of a citizen’s right to be free from involuntary confinement by his own government without due process of law.” Hamdi, 124 S.Ct. at 2647; see also id. at 2661 (Scalia, J., dissenting) (“The very core of liberty secured by our Anglo-Saxon system of separated powers has been freedom from indefinite imprisonment at the will of the Executive.”); Rasul, 124 S.Ct. at 2692 (“Executive imprisonment has been considered oppressive and lawless since John, at Runnymede, pledged that no free man should be imprisoned, dispossessed, outlawed, or exiled save by the judgment of his peers or by the law of the land.”) (quotation omitted). This right draws its force from — and would be meaningless without — -the ability of the citizen to challenge his detention through a petition for a writ of habeas corpus. See, e.g., Lonchar v. Thomas, 517 U.S. 314, 322, 116 S.Ct. 1293, 134 L.Ed.2d 440 (1996) (describing the writ as the “highest safeguard of liberty”) (quotation omitted); Harris v. Nelson, 394 U.S. 286, 290-91, 89 S.Ct. 1082, 22 L.Ed.2d 281 (1969) (“The writ of habeas corpus is the fundamental instrument for safeguarding individual freedom against arbitrary and lawless state action.”). The writ of habeas corpus — often termed the Great Writ— arose from the common law of England, was shaped in the forge of the early colonial experience, received recognition in the United States Constitution (the only common law writ to be so recognized) and the first Judiciary Act, and has evolved in countless legislative enactments and judicial rulings since. Throughout, the writ has stood as an indispensable safeguard of the freedom of citizens and a constant remedy against wrongful detention at the whim of the executive. See Rasul, 124 S.Ct. at 2692 (“The judges of England developed the writ of habeas corpus largely to preserve these immunities from executive restraint.”) (quotation omitted); Morgan, 346 U.S. at 506 n. 3, 74 S.Ct. 247 (“The writ of habeas corpus commands general recognition as the essential remedy to safeguard a citizen against imprisonment by State or Nation in violation of his constitutional rights.”) (quotation omitted); Ex parte Yerger, 75 U.S. (8 Wall.) 85, 95, 19 L.Ed. 332 (1868) (“The great writ of habeas corpus has been for centuries esteemed the best and only sufficient de-fence of personal freedom”) (emphasis in original). Consistent with its high purpose, courts have given the writ an exceptionally broad reach. “[MJodern habeas jurisprudence emphasizes the breadth and flexibility of the Great Writ in vindicating the fundamental concern in a democratic society of checking the powers of the state vis-a-vis an individual in custody.” Chatmam-Bey v. Thornburgh, 864 F.2d 804, 807 (D.C.Cir.1988) (en banc); see Ex parte McCardle, 73 U.S. (6 Wall.) 318, 325-26, 18 L.Ed. 816 (1867) (affirming that the habeas scheme is “of the most comprehensive character”); Johnson v. Avery, 393 U.S. 483, 485, 89 S.Ct. 747, 21 L.Ed.2d 718 (1969) (“The Court has steadfastly insisted that there is no higher duty than to maintain [the writ] unimpaired.”) (quotation omitted). The writ has accordingly been applied to a wide range of detentions of American citizens. See Rasul, 124 S.Ct. at 2692 (“Consistent with the historic purpose of the writ, this Court has recognized the federal courts’ power to review applications for habeas relief in a wide variety of cases involving Executive detention.”); Maleng v. Cook, 490 U.S. 488, 492, 109 S.Ct. 1923, 104 L.Ed.2d 540 (1989) (“[W]e have very liberally construed the ‘in custody’ requirement for purposes of federal habeas.”); see also 3 William Blackstone, Commentaries 131 (describing habeas as “the great and efficacious writ, in all manners of illegal confinement”). The D.C. Circuit, sitting en banc, has emphasized the “strong High Court disapproval of formalistic analysis in the context of habeas corpus” and instructed a court assessing whether the habeas statute applies to a particular form of custody to “cut[ ] through all forms” and affirm the purpose of the writ as a “fundamental safeguard against unlawful custody.” Chatman-Bey, 864 F.2d at 807 (quotation omitted); see Hensley v. Municipal Court, 411 U.S. 345, 350, 93 S.Ct. 1571, 36 L.Ed.2d 294 (1973) (explaining that the Court has “consistently rejected interpretations of the habeas corpus statute that would suffocate the writ in stifling formalisms”). Notwithstanding these principles, however, the United States argues that the habeas petition for Abu Ali should be dismissed as a matter of law, no matter how extensive a role the United States might have played and continues to play in his detention, for the sole reason that he is presently in a foreign prison. A federal court, they claim, “simply lacks jurisdiction to grant habeas relief where the prisoner seeking the writ is being held by a foreign custodian, even where the United States allegedly has been involved in the prisoner’s incarceration in the first place.” Resp’ts’ Supplemental Filing at 1-2. This argument rests on one fact and one fact alone: Abu Ali is presently being held by a foreign government. The moment this is the case, the United States claims, the courts are immediately stripped of jurisdiction over any habeas claim. This position is as striking as it is sweeping. The full contours of the position would permit the United States, at its discretion and without judicial review, to arrest a citizen of the United States and transfer her to the custody of allies overseas in order to avoid constitutional scrutiny; to arrest a citizen of the United States through the intermediary of a foreign ally and ask the ally to hold the citizen at a foreign location indefinitely at the direction of the United States; or even to deliver American citizens to foreign governments to obtain information through the use of torture. In short, the United States is in effect arguing for nothing less than the unreviewable power to separate an American citizen from the most fundamental of his constitutional rights merely by choosing where he will be detained or who will detain him. This Court simply cannot agree that under our constitutional system of government the executive retains such power free from judicial scrutiny when the fundamental rights of citizens have allegedly been violated. As the Supreme Court stated in Reid v. Covert, 354 U.S. 1, 6, 77 S.Ct. 1222, 1 L.Ed.2d 1148 (1957), “we reject the idea that when the United States acts against citizens abroad it can do so free of the Bill of Rights.... When the Government reaches out to punish a citizen who is abroad, the shield which the Bill of Rights and other parts of the Constitution provide to protect his life and liberty should not be stripped away just because he happens to be in another land.” The United States premises its claim to this power on three arguments of law: (i) what they perceive to be an “implicit territorial restriction on the Great Writ”; (ii) the contention that jurisdiction over the petition in this ease is foreclosed by the Supreme Court’s decision in Hirota v. General of the Army MacArthur, 338 U.S. 197, 69 S.Ct. 197, 93 L.Ed. 1902 (1948) (per curiam), and the D.C. Circuit’s decision in U.S. ex rel. Keefe v. Dulles, 222 F.2d 390 (D.C.Cir.1954); and (iii) the suggestion that federal jurisdiction over the habeas claim in this case would run afoul of the act of state, separation of powers, and political question doctrines. The Court will address each of these arguments in turn in the sections below. To briefly summarize its conclusions here, however, the Court holds that the United States may not avoid the habeas jurisdiction of the federal courts by enlisting a foreign ally as an intermediary to detain the citizen. The instances where the United States is correctly deemed to be operating through a foreign ally as an intermediary for purposes of habeas jurisdiction will be exceptional, and a federal court’s inquiry in such cases will be substantially circumscribed by the separation of the powers. Nonetheless, the executive’s authority over foreign relations has never in our nation’s history been deemed to override entirely the most fundamental rights of a United States citizen — the right to challenge as arbitrary and unlawful his detention allegedly at the will of the executive. This authority likewise has never been held to eliminate the essential remedy against such unlawful detentions — the Great Writ of habeas corpus. I. Standard of Review On a motion to dismiss for lack of jurisdiction, the petitioner bears the burden of establishing the jurisdiction of the Court. See Dist. of Columbia Ret. Bd. v. United States, 657 F.Supp. 428, 431 (D.D.C.1987); Gordon v. Ashcroft, 283 F.Supp.2d 435, 437 (D.Mass.2003). Where, as here, the respondents challenge only the legal sufficiency of the petitioners’ jurisdictional allegations, the district court should take the petitioners’ factual allegations as true, and draw all reasonable inferences in the petitioners’ favor. See Hawk v. Olson, 326 U.S. 271, 272, 66 S.Ct. 116, 90 L.Ed. 61 (1945); Phoenix Consulting, Inc. v. Republic of Angola, 216 F.3d 36, 39 (D.C.Cir.2000). The court need not limit itself to the allegations of the petition. See Hohri v. United States, 782 F.2d 227, 241 (D.C.Cir.1986), vacated on other grounds, 482 U.S. 64, 107 S.Ct. 2246, 96 L.Ed.2d 51 (1987). Instead, the court may consider any materials outside the pleadings as it deems appropriate to determine whether it has jurisdiction over the case. See Herbert v. Nat’l Acad, of Scis., 974 F.2d 192, 197 (D.C.Cir.1992). II. The Habeas Statute The federal district courts, as courts of limited jurisdiction, possess only such authority as is conferred by an act of Congress. See Kokkonen v. Guardian Life Ins. Co. of Am., 511 U.S. 375, 377, 114 S.Ct. 1673, 128 L.Ed.2d 391 (1994); Friends of the Earth v. United States Envtl. Prot. Agency, 333 F.3d 184, 187 (D.C.Cir.2003); Commodity Futures Trading Comm’n v. Nahas, 738 F.2d 487, 492 (D.C.Cir.1984). As a consequence, the Court must look, at least in the first instance, to the habeas statute to determine whether it has jurisdiction over the habeas petition in this case. See Rasul, 124 S.Ct. at 2694-96; Muhammad v. Bureau of Prisons, No. 04-1114, 2004 WL 2191631, at *1 (D.C.Cir. Sept.24, 2004). The relevant sections of the habeas statute for present purposes are located in 28 U.S.C. §§ 2241-43. The authority of the district courts to issue the writ is set out in section 2241. That section provides, in relevant part: (a) Writs of habeas corpus may be granted by the Supreme Court, any justice thereof, the district courts and any circuit judge within their respective jurisdictions. The order of a circuit judge shall be entered in the records of the district court of the district wherein the restraint complained of is had. (c) The writ of habeas corpus shall not extend to a prisoner unless— (1) He is in custody under or by color of the authority of the United States or is committed for trial before some court thereof; or (2) He is in custody for an act done or omitted in pursuance of an Act of Congress, or an order, process, judgment or decree of a court or judge of the United States; or (3) He is in custody in violation of the Constitution or laws or treaties of the United States .... 28 U.S.C. § 2241. Section 2242 contains several rules regarding the information that must be placed in the application for the writ of habeas corpus, including that the application “shall allege the facts concerning the applicant’s commitment or detention, the name of the person who has custody over him and by virtue of what claim or authority, if known.” Id. § 2242. Finally, section 2243 addresses the issuance of a writ by the court and provides, inter alia, that the writ “shall be directed to the person having custody of the person detained,” and the “person to whom the writ is directed shall be required to produce at the hearing the body of the person detained.” Id. § 2243. A. The Supposed “Implicit Territorial Limitation” on the Writ The United States argues that these sections contain what they call an “implicit territorial limitation of the Great Writ.” Resp. Show Cause at 3. They insist that threaded through the provisions excerpted above is an absolute requirement that a citizen’s habeas petition name as a respondent the immediate custodian who is exercising physical control over the petitioner, and that this immediate custodian be “within the[] respective jurisdiction” of the district court. See id. Where the immediate custodian does not lie in the jurisdiction of the district court, the United States maintains, then the district court lacks habeas jurisdiction; and where there is no immediate custodian within the territorial jurisdiction of any district court, then no court has jurisdiction of the citizen’s petition at all. See id. This position is foreclosed by a line of precedent culminating in two recent Supreme Court cases. In the first of those cases, Rumsfeld v. Padilla, — U.S. -, 124 S.Ct. 2711, 159 L.Ed.2d 513 (2004), the Court dismissed the habeas petition of an American citizen detained in a Naval Brig in Charleston, South Carolina, that was filed in the Southern District of New York and named as respondents several government officials who were outside of the jurisdiction of that court. The Court based its conclusion on two principles that confine habeas: the “immediate custodian” and the “district of confinement” rules. Id. at 2718-21, 2724-25. Together, the Court explained, these rules stand for the proposition that “in habeas challenges to present physical confinement — ‘core challenges’ — the default rule is that the proper respondent is the warden of the facility where the prisoner is being held, not the Attorney General or some other remote supervisory official,” and that the petitioner must file the petition in the district court for the district in which he is confined. Id. at 2717, 2724-25. The Court explained, however, that there is a “recognized” exception to these rules in cases where “American[] citizens confined overseas (and thus outside the territory of any district court) have sought relief in habe-as corpus.” Braden [v. 30th Judicial Circuit Court of Ky., 410 U.S. 484, 498, 93 S.Ct. 1123, 35 L.Ed.2d 443 (1973) ] (citing cases). In such cases, we have allowed the petitioner to name as respondent a supervisory official and file the petition in the district where the respondent resides. Id. at 2718, 2725 n. 16; see also id. at 2718 n. 9. The Court cited two cases where it allowed American citizens overseas to challenge the legality of their detention in habeas in the United States District Court for the District of Columbia notwithstanding the immediate custodian and district of confinement rules: Burns v. Wilson, 346 U.S. 137, 73 S.Ct. 1045, 97 L.Ed. 1508 (1953), where a court-martial convict incarcerated in Guam sued the Secretary of Defense, and United States ex rel. Toth v. Quarles, 350 U.S. 11, 76 S.Ct. 1, 100 L.Ed. 8 (1955), where a court-martial convict incarcerated in Korea sued the Secretary of the Air Force. The same day that it decided Padilla, the Supreme Court held in Rasul v. Bush that this Court — the United States District Court for the District of Columbia — had jurisdiction to entertain the habeas petition of a non-resident alien detained at Guantanamo Bay, Cuba. 124 S.Ct. at 2698. In reaching that conclusion, the Supreme Court was required to consider whether the presence of the petitioner outside the jurisdiction of any district court divested the federal district courts of jurisdiction. As it had done in Padilla, the Court read Braden v. 30th Judicial Circuit Court of Ky. to hold that the presence of the petitioner in the territorial jurisdiction of the district court is not “ ‘an invariable prerequisite’ ” to habeas jurisdiction. Rasul, 124 S.Ct. at 2695 (quoting Braden, 410 U.S. at 495, 93 S.Ct. 1123). Rasul noted that Bra-den had been a departure from prior precedent in this regard, and that Braden had explained the departure by citing developments in the law that “had a profound impact on the continuing vitality” of that precedent. Id. Rasul observed that these developments “notably” included cases where the Court found habeas jurisdiction over the petitions of individuals “ ‘confined overseas (and thus outside the territory of any district court).’ ” Id. at 2695 (quoting Braden, 410 U.S. at 498, 93 S.Ct. 1123 (citing Burns and Toth)). Continuing to rely upon Braden, Rasul explained that “the writ of habeas corpus does not act upon the prisoner who seeks relief, but upon the person who holds him in what is alleged to be unlawful custody,” a district court acts “within its respective jurisdiction within the meaning of § 2241 as long as the custodian can be reached by service of process.” Id. (quotation and alteration omitted). Therefore, the mere presence of the petitioner in Rasul (and, it follows, his immediate custodian) outside the jurisdiction of any district court did not preclude him from bringing a habeas petition in the United States District Court for the District of Columbia, and from naming as respondents various “custodians,” who included the President of the United States, the Secretary of Defense, and others. See id. at 2695, 2698. It is noteworthy that these were precisely the kind of “remote supervisory official[s]” that Padilla had explained the same day could not be named as respondents under the “immediate custodian” rule unless some exception to that rule applied. The United States’ arguments cannot plausibly survive these cases. The decisions of the Court finding an absence of jurisdiction in Padilla and the existence of jurisdiction in Rasul share at least one common feature: both recognize an exception to the “immediate custodian” and “district of confinement” rules when the petitioner and his immediate custodian are “outside the territory of any district court.” Braden, 410 U.S. at 498, 93 S.Ct. 1123. Where that is the case, the petitioner may name as respondents any of his custodians (not just the immediate custodians) and may file the claim in the court that has jurisdiction over those respondents. See, e.g., Gherebi v. Bush, 338 F.Supp.2d 91, 95 (D.D.C.2004) (citing Padilla and Rasul for the conclusion that individuals detained in Guantanamo Bay may bring a habeas petition in the United States District Court for the District of Columbia that names Secretary Rumsfeld as a respondent under the exception to the “immediate custodian” and “district of confinement” rules). Respondents struggle mightily to respond to this exception. They suggest that the passages in Padilla discussing the exception can be ignored as dicta, because neither Padilla nor Braden in fact involved petitioners who were outside of the United States, and because Burns and Toth, the two decisions cited in Padilla, do not specifically address the jurisdiction of the Court. Resp. Show Cause at 12-13. At the outset, this description of the law is wrong. Burns stated quite explicitly that there was habeas jurisdiction under 28 U.S.C. § 2241 to review the constitutional claims of an American citizen court-mart-ialed in Guam: [W]e are dealing with habeas corpus applicants who assert — rightly or wrongly — that they have been imprisoned and sentenced to death as a result of proceedings which denied them basic rights guaranteed by the Constitution. The federal civil courts have jurisdiction over such applications. By statute, Congress has charged them with the exercise of that power. Burns, 346 U.S. at 139, 73 S.Ct. 1045 (citing 28 U.S.C. § 2241). At any rate, this Court cannot disregard a rule of law that the Supreme Court described as “recognized” in one recent decision (Padilla); that was at the heart of both the reasoning and the outcome in another recent decision (Rasul); that it discussed in some detail in an earlier decision (Braden); and that was necessary to the holding of one decision involving an American citizen detained overseas (ex rel. Toth, where the Court affirmed the district court’s issuance of the writ), and to the analysis of another (Burns, where the Court declined to issue the writ, but nevertheless addressed its jurisdiction over, and then the merits of, the petitioner’s claim). This is far more than the concept of “dicta” can bear. Respondents also maintain that the exception “abandons” the “immediate custodian” and “district of confinement” rules and treats them as nothing more than a “policy rule.” Resp’ts’ Opp’n Mot. Prelim. Inj. at 13. That is far from the truth. The rules have continuing vitality and are rigorously applied. As Rasul explained, however, they are “strictly relevant only to the question of the appropriate forum, not to whether the claim can be heard at all.” Rasul, 124 S.Ct. at 2695. In Padilla, for example, the Supreme Court concluded that the United States District Court for the Southern District of New York lacked jurisdiction to hear the habeas petition of an individual incarcerated in a Naval Brig in South Carolina, and that the petitioner would therefore need to re-file his petition in the United States District Court for the District of South Carolina instead. See 124 S.Ct. at 2727. The “immediate custodian” and “district of confinement” rules continue to play an important role in channeling a habeas petition into the court with jurisdiction over the petitioner and his immediate custodian, when possible. That said, the law is clear that the scattered references in the habeas statute to “the person having custody of the person detained” and the courts exercising jurisdiction “within their respective jurisdictions” simply do not add up to a jurisdictional wall against habeas petitions for citizens detained overseas, implicit (as the United States would have it) or otherwise. To be sure, this is just the beginning of the jurisdictional inquiry. The absence of a broad rule precluding federal jurisdiction over the habeas petition of a citizen held overseas (regardless of who is holding him) leaves remaining the question whether there ever can be habeas jurisdiction over the petition of a citizen held overseas in the specific circumstance where he is held by a foreign state. That issue raises serious and important questions of law that require careful assessment of the text of the habeas statute, decades of precedent regarding the meaning of the term “custody” in the statute, and important constitutional considerations on both sides of the ledger. It is to those questions that the Court now turns. B. “In Custody” The turnkey of the habeas statute is the requirement of custody. The statute provides specifically that a district court cannot issue a writ of habeas corpus to an individual unless the individual “is in custody” either “under or by color of the authority of the United States” or “in violation of the Constitution or laws or treaties of the United States,” or in several other respects that are not claimed to be relevant here. 28 U.S.C. § 2241(c). This case requires the Court to determine whether an individual is “in custody” within the meaning of one or both of these provisions when he is allegedly arrested and held by a foreign agent at the behest or direction of the United States. An analysis of the “in custody” language of the habeas statute must start with the proposition that the Supreme Court has “very liberally construed the ‘in custody’ requirement for purposes of federal habe-as.” Maleng, 490 U.S. at 492, 109 S.Ct. 1923; see also Peyton v. Rowe, 391 U.S. 54, 64, 88 S.Ct. 1549, 20 L.Ed.2d 426 (1968) (holding that the “in custody” requirement of the habeas statute “should be liberally construed” because of the remedial goals of the statute). In fact, the Court has explained that although the habeas statute limits “its availability to those ‘in custody,’ the statute does not attempt to mark the boundaries of ‘custody’ nor in any way other than by use of that word attempt to limit the situations in which the writ can be used.” Jones v. Cunningham, 371 U.S. 236, 243, 83 S.Ct. 373, 9 L.Ed.2d 285 (1963); see also Hensley, 411 U.S. at 350, 93 S.Ct. 1571 (“The custody requirement of the habeas corpus statute is designed to preserve the writ of habeas corpus as a remedy for severe restraints on individual liberty.”). When determining whether a petition falls within the “in custody” language of the habeas statute, courts must avoid “legalistic” and “formalistic” distinctions and honor the “breadth and flexibility of the Great Writ.” Morgan, 346 U.S. at 506 n. 3, 74 S.Ct. 247 (quotation omitted); Chat-man-Bey, 864 F.2d at 807. The Supreme Court has often underscored the “most comprehensive character” of the habeas statute and advised that “there is no higher duty than to maintain” the writ “unimpaired.” Johnson, 393 U.S. at 485, 89 S.Ct. 747; Ex parte McCardle, 73 U.S. (6 Wall.) at 325-26, 18 L.Ed. 816; see also Burns, 346 U.S. at 148, 73 S.Ct. 1045 (statement of Frankfurter, J.) (“The right to invoke habeas corpus to secure freedom is not to be confined by any a priori or technical notions of ‘jurisdiction.’ ... And so, if imprisonment is the result of a denial of due process, it may be challenged no matter under what authority of Government it was brought about.”). Although it devotes somewhat less attention to this theory than to its “immediate custodian” argument, the United States appears to contend that the statutory phrase “in custody” only encompasses cases where the individual is in the actual physical custody of a United States official. See Resp. Show Cause at 3, 7 n. 5. The text of the statute, however, is not nearly so limiting. Section 2241(c)(1) expressly expands the compass of habeas jurisdiction to any petitioner who is “in custody under or by color of the authority of the United States,” not just to those strictly in the custody of the United States. 28 U.S.C. § 2241(c)(1) (emphasis added). Section 2241(c)(3) sweeps even more broadly, encompassing any individual who is “in custody”— without the limitation of “under or by color of the authority of the United States” — so long as the custody is “in violation of the Constitution or laws or treaties of the United States.” 28 U.S.C. § 2241(c)(3). No one doubts that there must be some involvement of United States officials under either provision to satisfy the “in custody” requirement. However, any attempt to read a requirement that the individual be in the actual physical custody of the United States does not find footing in the text of the statute itself. Indeed, consistent with the broad language in the statute, courts have universally held that actual physical custody of an individual by the respondent is unnecessary for habeas jurisdiction to exist. See Justices of Boston Municipal Ct. v. Lydon, 466 U.S. 294, 300, 104 S.Ct. 1805, 80 L.Ed.2d 311 (1984) (“Our cases make clear that the use of habeas corpus has not been restricted to situations in which the applicant is in actual, physical custody.”) (quotation omitted); Galaviz-Medina v. Wooten, 27 F.3d 487, 492 (10th Cir.1994) (the custody concept “includes many situations where the petitioner is not in actual physical custody”). Courts instead have read the language of the statute to provide for habeas jurisdiction where the official possesses either actual or “constructive” custody of the petitioner. See LoBue v. Christopher, 82 F.3d 1081, 1082 (D.C.Cir.1996) (individual released on bail pending his challenge to the federal extradition statute was “in the constructive custody of the U.S. Marshall for the Northern District of Illinois” and therefore could “challenge the statute through a petition for habeas corpus there”); Keefe, 222 F.2d at 392 (question of habeas jurisdiction turns on whether the petitioner “is held in actual or constructive custody by the respondents named in the petition, or by any other person or persons subject to the jurisdiction of the District Court”). The Sixth Circuit has described the concept of constructive custody as follows: In order to maintain a habeas corpus action, the petitioner must be “in custody.” His custody must be the result of the respondent’s action from which he seeks habeas corpus relief. However, the Supreme Court has given the custody requirement a liberal construction, and it is not necessary that the petitioner be in physical control of the respondent. It is enough that the imprisoning sovereign is the respondent’s agent; that his liberty is restrained by the respondent’s parole conditions; or that he can point to some continuing collateral disability which is the result of-the respondent’s action. Steinberg v. Police Court of Albany, N.Y., 610 F.2d 449, 453 (6th Cir.1979) (citations omitted). There are, in fact, many circumstances in which courts have found actual or constructive custody notwithstanding the fact that the petitioner was not in the physical custody of the respondent government official. These include cases where the petitioner is imprisoned in one state and subject to a detainer in the respondent’s state, see Braden, 410 U.S. at 484, 93 S.Ct. 1123; the petitioner is in federal or state prison and is subject to a final order of deportation by the respondent Immigration and Naturalization Service, see Galaviz-Medina, 27 F.3d at 493; the petitioner is on probation or parole and is restrained by conditions imposed by the respondent officials, see Jones v. Cunningham, 371 U.S. 236, 243, 83 S.Ct. 373, 9 L.Ed.2d 285 (1963); the petitioner is released on his own recognizance awaiting trial or sentencing, see Justices of Boston Municipal Ct., 466 U.S. at 300-01, 104 S.Ct. 1805; and the petitioner is denied entry to a tribe or to the United States but is otherwise a free man, see Subias v. Meese, 835 F.2d 1288, 1289 (9th Cir.1987); Poodry v. Tonawanda Band of Seneca Indians, 85 F.3d 874, 894 (2d Cir.1996). In some of these cases, the petitioner was not in the physical control of the petitioner, but was in the physical control of some other entity. In others, the petitioner was not in the physical control of any entity at all. Nevertheless, in all of these decisions, the petitioner was found to be in the actual or constructive custody of the respondent within the meaning of the habeas statute because the respondent was responsible for significant restraints on the petitioner’s liberty. See Hensley, 411 U.S. at 351, 93 S.Ct. 1571 (“The custody requirement of the habeas corpus statute is designed to preserve the writ of habeas corpus as a remedy for severe restraints on individual liberty.”); Poodry, 85 F.3d at 894 (habeas jurisdiction exists not just in physical custody by the executive but in all circumstances in which “federal adjudication is necessary to guard against governmental abuse in the imposition of severe restraints on individual liberty.”) (quotation omitted). Of a piece with this well-settled law are several decisions in which a court has found a petitioner to be in the actual or constructive custody of a respondent official who was working through an intermediary or an agent to detain the prisoner. For example, in Braden, the Supreme Court held that a petitioner was “in custody” of the Commonwealth of Kentucky even though he was incarcerated by the State of Alabama, because Kentucky had issued a detainer that was being executed against the petitioner by Alabama. In those circumstances, the Court explained, the Alabama warden was acting “as the agent of the Commonwealth of Kentucky in holding the petitioner pursuant to the Kentucky detainer,” and the Court therefore had “no difficulty concluding” that petitioner was in the custody of Kentucky for purposes of a habeas petition challenging the charge underlying the Kentucky detainer. Braden, 410 U.S. at 489 n. 4, 93 S.Ct. 1123; see also id. at 498-99, 93 S.Ct. 1123 (“In such a case, the State holding the prisoner in immediate confinement acts as agent for the demanding State, and the custodian State is pr
