OPINION

ROSEMARY M. COLLYER, District Judge.

On a petition for a writ for habeas corpus filed by a detainee at Guantanamo Bay, may the Respondents rely on Top Secret source-identifying information for which there is no adequate substitute and that cannot be released to Petitioner's counsel, even if it might assist his petition? After lengthy argument, briefing, and consideration, this Court answered the question in the affirmative and now writes to explain its conclusions.

I. FACTS

Petitioner Wali Mohammed Morafa, an Afghan citizen, is a detainee at Guantánamo Bay Naval Station in Cuba. Respondents contend that he "used the cover of [] otherwise legitimate money-changing activities to provide financial services support to the operations of the Taliban, [Al Qaida, Usama Bin Laden], and other terrorist organizations," including "financ[ing]. . . operations and terror attacks." Notice of Public Filing of Factual Return [Dkt. 242], Narrative [Dkt. 242-1] ¶ 01. With a group of other detainees, he filed his petition for a writ of habeas corpus on June 7, 2005. See Pet. [Dkt. 1]; see also Am. Pet. [Dkt. 22]. On January 27, 2006, this Court ordered the case held in abeyance pending a ruling from the D.C. Circuit on whether the Court had jurisdiction to entertain the petition. See Order dated Jan. 27, 2006 [Dkt. 33]. Thereafter, in events whose intricate details are not directly relevant to the issues presently before the Court, the case was effectively stayed for a lengthy period pending various rulings from the D.C. Circuit and the Supreme Court addressing what vehicle, if any, Guantánamo detainees could use to challenge their detention. In addition, during that time period, procedural and logistical matters in this case were consolidated for coordination and management with other Guantánamo cases before the Honorable Thomas F. Hogan in Case Misc. No. 08-442. See Order dated July 2, 2008 [Dkt. 85].

On November 25, 2008, respondents filed their classified Factual Return regarding Mr. Morafa, see Notice of Filing of Factual Returns, Dkt. 143, and they served an unclassified version on Mr. Morafa's counsel shortly thereafter, see Notice of Service of Unclassified Protected Factual Return, Dkt. 170. See also Notice of Public Filing of Factual Return. In January 2009, after President Barack Obama took office, Respondents notified the Court that they had identified additional documents, possibly relevant to Mr. Morafa, that were undergoing clearance review. See Supp. Notice Prod. Exculp. Info. [Dkt. 183] at 1. In December 2009, Respondents sought leave to amend the factual return, see Notice of Classified Filing dated Dec. 1, 2009, Dkt. 257; Mr. Morafa consented, see Revised Notice dated Dec. 7, 2009, Dkt. 260, and the Court granted the motion and set a briefing schedule, Minute Order dated Dec. 11, 2009. Mr. Morafa filed his traverse on January 15, 2010. See Notice of Filing [Dkt. 264]. The parties filed a number of additional motions and briefs, and the Court held a closed merits hearing over several days in May and June 2010.

Although the case's dénouement seemed nigh, matters were not so simple. Following a November 5, 2010, telephone conference, the Court reopened the record and approved additional briefing to accommodate ongoing document review by Respondents, necessary for Respondents to ensure full compliance with their disclosure obligations. See Minute Orders dated Nov. 5, 2010 & Nov. 23, 2010. See generally Am. Case Mgmt. Order [Dkt. 154] §§ 1.D, 1.E. Respondents filed a Supplemental Factual Return on March 25, 2011. See Notice of Filing [Dkt. 331].

The discovery fights then renewed. Contending that he was entitled to additional materials from Respondents, Mr. Morafa filed a motion for additional discovery. See Notice of Filing dated July 18, 2011 [Dkt. 339]. Following status conferences on October 18 and November 3, 2011, the Court granted the motion in part and directed Respondents to conduct five additional searches on terms set forth in an Order dated November 15, 2011. See Order on Pet'r Mot. Add'l Disc. (Redacted Version) [Dkt. 356]. Respondents located additional information inculpating Mr. Morafa, and they filed a motion to add this information to the Supplemental Factual Return, see Notice of Classified Filings [Dkt. 366], which the Court granted, see Order dated July 23, 2012 [Dkt. 372] at 2.

The present issue arises from certain source-related information located by Respondents during their searches after November 2011. The information in question is classified at the "Top Secret" level, the highest of the three levels of national security classification—Top Secret, Secret, and Confidential.1 Throughout the Guantánamo proceedings, counsel for petitioners, including Mr. Morafa's attorneys, have only held clearance at the Secret level, making them ineligible to access to Top Secret information. See Am. Case Mgmt. Order § 1.F ("If any information to be disclosed under Sections I.D or I.E of this Order is classified, the government shall, unless granted an exception by the Merits Judge, provide the petitioner's counsel with the classified information, provided the petitioner's counsel is cleared to access such information." (emphasis added)). Accordingly, Respondents filed a motion ex parte and in camera, Dkt. 374, for an exception to their disclosure duties with respect to certain information, including the source-related information at issue here. See Am. Case Mgmt. Order § 1.F ("If the government objects to providing the petitioner's counsel with the classified information, the government shall move for an exception to disclosure.").

Thereafter, pursuant to a procedure used by other judges of this Court in Guantánamo cases and endorsed by the D.C. Circuit in Khan v. Obama, 655 F.3d 20 (2011), the Court reviewed Respondents' ex parte materials in camera. The Court also reviewed proposed substitutes, classified below the Top Secret level, that Respondents intended to provide to Mr. Morafa's counsel. These substitutes are a unique device to balance national security needs with the need for "meaningful" habeas review. See Khan, 655 F.3d at 32 (quoting Boumediene v. Bush, 553 U.S. 723, 779, 128 S.Ct. 2229, 171 L.Ed.2d 41 (2008)). They generally describe, in less detail or with certain omissions or redactions, the classified information that could not be disclosed. If approved by the court, they are referred to as "adequate substitutes." A court's inquiry when reviewing proposed substitutes is, essentially, to determine if all "relevant and material" information from the Top Secret document has been conveyed in the Secret substitute. See Al Odah v. United States, 559 F.3d 539, 544 (D.C.Cir.2009) (applying "relevant and material" standard to disclosure of Secret classified information to petitioner's counsel in Guantánamo case). If so, the petitioner has access to "meaningful" habeas review, and the fact that there is some information to which petitioner's counsel does not have access is irrelevant because that information falls short of being "relevant and material." See id.

The problem arises when there is "relevant and material" evidence, classified as Top Secret, for which no adequate substitute is available. This is an issue that, to the knowledge of the Court and the parties, has never been directly resolved—likely owing in large part to the good faith shown by Respondents in working with stakeholder agencies and with judges during ex parte, in camera review to reach agreement as to adequate substitutes that petitioners' counsel can access. Despite the commendable and professional efforts of Respondents' counsel, this case presented that problem: there is no adequate substitute available for certain relevant and material source-related information, classified at the Top Secret level. Accordingly, although the Court has reviewed that information in camera, Mr. Morafa's counsel is unable to review it. Mr. Morafa objects to this outcome, arguing that the unavailability of such evidence to counsel must both preclude Respondents from relying on it to support his detention and preclude the Court from considering it in ruling on his habeas petition.

After oral arguments held during closed hearings on August 24, 2012 and September 18, 2012, the Court issued oral rulings that Respondents were not required to disclose the Top Secret materials for which no adequate substitute could be prepared and had, subsequent to some additional substitute disclosures to which Respondents agreed, satisfied their disclosure obligations.2 At Mr. Morafa's request, the Court allowed the parties to file further memoranda regarding these matters. See Minute Order dated Sept. 27, 2012. The parties filed their memoranda, see Resp't Mem. [Dkt. 378] & Pet'r Mem. [Dkt. 383], and the matter is now ready for disposition.3

II. ANALYSIS

Boumediene v. Bush, 553 U.S. 723, 128 S.Ct. 2229, 171 L.Ed.2d 41 (2008), examined the rights of detainees at Guantánamo Bay to habeas proceedings and invalidated § 7 of the Military Commissions Act of 2006,4 which had cut off detainee access to habeas relief in federal courts. Id. at 792, 128 S.Ct. 2229 ("MCA § 7 thus effects an unconstitutional suspension of the writ."). It found:

Id. at 783, 128 S.Ct. 2229. To conduct a proper habeas proceeding, the court must have "some authority to assess the sufficiency of the Government's evidence against the detainee." Id. at 786, 128 S.Ct. 2229. "It also must have the authority to admit and consider relevant exculpatory evidence. . . ." Id. The detainee must have an "opportunity . . . to present relevant exculpatory evidence. . . ." Id. at 789, 128 S.Ct. 2229. For emphasis, the Court reiterated: "If a detainee can present reasonably available evidence demonstrating there is no basis for his continued detention, he must have the opportunity to present this evidence to a habeas corpus court." Id. at 790, 128 S.Ct. 2229. And again, "[i]n this context, however, where the underlying detention proceedings lack the necessary adversarial character, the detainee cannot be held responsible for all deficiencies in the record" and must be allowed to present evidence to the court even if such evidence were not available earlier, when the military detention decision was made. Id. at 791, 128 S.Ct. 2229.

Nonetheless, "it does not follow that a habeas corpus court may disregard the dangers the detention in these cases was intended to prevent." Id. at 795, 128 S.Ct. 2229. "Certain accommodations can be made to reduce the burden habeas corpus proceedings will place on the military without impermissibly diluting the protections of the writ." Id. Indeed, one of the reasons all Guantánamo habeas cases are venued in the District of Columbia is to "avoid the widespread dissemination of classified information." Id.

Id.; see also id. ("These and the other remaining questions are within the expertise and competence of the District Court to address in the first instance."). Given these imprecise instructions from the High Court, the judges of this Bench and Circuit have developed precedents which aid the analysis on the immediate point.

Applying Boumediene, the D.C. Circuit has held that "[t]he Suspension Clause protects only the fundamental character of habeas proceedings, and any argument equating that fundamental character with all the accoutrements of habeas for domestic criminal defendants is highly suspect." Al-Bihani v. Obama, 590 F.3d 866, 876 (2010). It added, "Detention of aliens outside the sovereign territory of the United States during wartime is a different and peculiar circumstance, and the appropriate habeas procedures cannot be conceived of as mere extensions of an existing doctrine." Id. at 877. The D.C. Circuit has found that Guantánamo detainees receive only "limited procedural entitlement," id. at 878, which does not include a right to confront a detainee's accusers, guaranteed to criminal defendants under the Sixth Amendment, because it "is not directly relevant to the habeas setting," id. at 879 (citation omitted). Rather,

Id. at 880 (emphasis added).

Al Odah v. United States, 559 F.3d 539 (D.C.Cir.2009), which preceded Al-Bihani, addressed the disclosure of information classified as Secret to a Guantánamo petitioner's counsel. By reference to criminal proceedings, the D.C. Circuit held that "before the district court may compel the disclosure of classified information, it must determine that the information is both relevant and material—in the sense that it is at least helpful to the petitioner's habeas case." Id. at 544. In the context of a habeas proceeding, this means that "the court must further conclude that access by petitioner's counsel (pursuant to a court-approved protective order) is necessary to facilitate such review." Id. at 545. For this purpose, Khan v. Obama, 655 F.3d 20 (D.C.Cir.2011), accepted a process by which the District Court judge reviewed certain materials ex parte and in camera and petitioner's counsel, who had suggested the procedure, received a only a substitute declaration—"still classified, but with less sensitive information"—describing the evidence. Id. at 31.

As summarized above, in the instant matter, the Court adopted the process endorsed in Khan. It has reviewed all Top Secret evidence ex parte and in camera to ensure that Mr. Morafa's counsel received Secret versions that are adequate substitutes. See Khan, 655 F.3d at 31 (noting that "highly sensitive" information "can be shown to the court . . . alone" (internal quotation marks and citation omitted)). Indeed, Khan concluded that "the combination of the government's declaration [shared with Mr. Khan's counsel] and the in camera submission [to the court but not counsel] constitute[d] an `effectiv[e] substitute for unredacted access' that ensures Khan the `meaningful review of both the cause for detention and the Executive's power to detain' required by Boumediene." Id. (citation omitted).

This case presents a new wrinkle. In reviewing all Top Secret information and redacted documents provided to Mr. Morafa's counsel, the Court has found that redactions were entirely proper as relevant here and that Respondents did a highly professional job preparing Secret substitutes—with the exception of substitutes for some source information. Respondents insist that such source information is much too highly sensitive to be disclosed to Mr. Morafa's lawyers, who are cleared to see only Secret information. Respondents rely on Boumediene's recognition that "the Government has a legitimate interest in protecting sources and methods of intelligence gathering," Resp't Mem. at 12 (quoting 553 U.S. at 795, 128 S.Ct. 2229); clearly, revelation of one may perforce constitute revelation of both. Because of the nature of some of the source information, the Court has also concluded that it might be relevant and material, i.e., "helpful to the petitioner's case." Al-Odah, 559 F.3d at 544; see also id. at 546 ("Information that . . . names potential witnesses . . . may . . . be material."). Counsel for Mr. Morafa most emphatically neither suggest nor agree that it is sufficient for the Court alone to review relevant and material Top Secret information that is not disclosed in any fashion to them. They argue that the Court should "use its discretion to accommodate [Respondents'] interest to the greatest extent possible." Pet'r Mem. at 7 (quoting Boumediene, 553 U.S. at 795, 128 S.Ct. 2229). According to Mr. Morafa's counsel, this means that Respondents have a choice in this case: either disclose the relevant and material source information to them or refrain from reliance on any document that stems from such a source. E.g., id. at 1-2. In the circumstances of this habeas petition, years after Mr. Morafa was transferred to Guantánamo, his counsel contend that his rights to contest Respondents' reasons for detention prevail over Respondents' need to secure source information, when revealed under a court protective order.

There is no doubt that the habeas proceedings for Guantánamo detainees constitute a special form of habeas for which a court must ensure an objective and neutral decisionmaker. As with all petitions for habeas corpus, these are not criminal proceedings, and simply analogizing to the rights of criminal defendants is inapt. Boumediene made clear that a Guantánamo detainee must have the right to present "reasonably available evidence," id. at 790, 128 S.Ct. 2229, and that the District Court must exercise its discretion in difficult evidentiary matters. This case presents such an occasion.

Some source information contained in Top Secret documents reviewed in camera and ex parte could be relevant and material to Mr. Morafa's case. However, Respondents have argued persuasively that source and method information are particularly critical within the Intelligence Community and the nation's security and, thus, cannot be revealed to Mr. Morafa's counsel. The Court agrees. It is true that this ruling will have a minor detrimental impact on Mr. Morafa's ability to contest the basis for his detention. However, the Court concludes that the incremental value to the Court of considering that evidence, in tandem with the "exceptionally grave damage to the national security" that could result from the unauthorized disclosure of Top Secret information, see 75 Fed.Reg. at 707-08,5 outweighs the marginal impact of withholding the information in question. See Khan, 655 F.3d at 31 ("[T]he government may offer alternatives to providing classified information, as long as they suffice to provide the detainee with a meaningful opportunity to demonstrate that he is being held pursuant to the erroneous application or interpretation of relevant law." (internal quotation marks and citations omitted)).

Of the three components to the habeas proceeding—(1) Mr. Morafa's ability to present affirmative evidence or, as relevant here, to attack Respondents' evidence; (2) Respondents' ability to protect highly sensitive information; and (3) the Count's ability, as a neutral decisionmaker, to seize "the actual truth of a simple, binary question: is detention lawful?," Al-Bihani, 590 F.3d at 880—the third is by far the most important aspect, as the D.C. Circuit and Supreme Court have both emphasized in Guantánamo cases. The primacy of the Court's independent review of the evidence is the defining feature of these proceedings precisely because "the one constant in the history of habeas has never been a certain set of procedures, but rather the independent power of a judge to assess the actions of the Executive." Al-Bihani, 590 F.3d at 880; see also Boumediene, 553 U.S. at 739-46, 128 S.Ct. 2229 (surveying history of habeas proceedings). What matters most is that the Court "have sufficient authority to conduct a meaningful review of both the cause for detention and the Executive's power to detain." Boumediene, 553 U.S. at 783, 128 S.Ct. 2229. In this context, the ultimate question is whether access by Mr. Morafa's counsel to Top Secret information is necessary to facilitate the Court's own meaningful review of the evidence. Al Odah, 559 F.3d at 545. Under these circumstances, the Court concludes that it is not.

The Court recognizes that its ruling necessarily impacts counsel's ability to access evidence that is relevant and material (but not necessary to facilitate review) and does not dismiss lightly the arguments counsel to Mr. Morafa have made or the frustration they experience in trying to expand the universe of "reasonably available evidence," Boumediene, 553 U.S. at 790, 128 S.Ct. 2229, from which to argue for their client. Top Secret source information is not reasonably available to those with Secret clearances. However, the value of this specific evidence is, at best, marginal: The underlying information provided by any source has been revealed to Mr. Morafa's counsel, by way of a properly redacted document or a proper adequate substitute. Thus, Mr. Morafa's counsel already can argue its accuracy and present his side. See Khan, 655 F.3d at 29 n. 7 ("The relevant question is not the number of independent sources but rather the reliability of their evidence. . . ."). Disclosure of source-identifying information might allow Mr. Morafa's counsel to sharpen any attack on a source's credibility but, to be frank, the nature of the classified information already revealed immediately lends itself to such an attack.

Finally, in considering Respondents' interest in protecting classified information from unauthorized disclosure, the information at issue here—source-identifying information—is one that courts have recognized as deserving special protection both inside and outside the arena of Guantánamo litigation. See, e.g., Fitzgibbon v. CIA, 911 F.2d 755, 762 (D.C.Cir.1990) ("[A]long with sources, methods constitute `the heart of all intelligence operations.' It is not the province of the judiciary . . . to determine whether a source or method should be disclosed. . . ." (quoting CIA v. Sims, 471 U.S. 159, 167, 105 S.Ct. 1881, 85 L.Ed.2d 173 (1985))); see also Al Odah v. United States, 608 F.Supp.2d 42, 45 (D.D.C.2009) (citing Fitzgibbon). Especially where, as here, a Guantánamo prisoner has access to the substance of the information provided by such sources, the Court recognizes the strong national security interest in protection of the identity of those sources.

Habeas petitions from Guantánamo detainees have continually presented courts with unique challenges, requiring development of new doctrines and procedures. See Al-Bihani, 590 F.3d at 877 (describing these cases as "a whole new branch of the tree"). Boumediene did not decide the instant issue, leaving it to the discretion of the district court. The D.C. Circuit has not addressed it with specificity but indicated its opinion in Khan. Without negative direction from superior courts, this Court concludes and finds that Top Secret information of the kind at issue here must be available to the neutral decisionmaker even if not disclosed to Mr. Morafa's counsel. With respect to the excellent lawyering from both parties, the Court ultimately finds that this is not a difficult question.
