The Tribunal’s findings regarding the Uighur group rest, in key respects, on statements in classified State and Defense Department documents that provide no information regarding the sources of the reporting upon which the statements are based, and otherwise lack sufficient indicia of the statements’ reliability. . . . The grounds for the charges that ETIM was “associated” with al Qaida and the Taliban, and that it is engaged in hostilities against the United States or its coalition partners, were statements in classified documents that do not state (or, in most instances, even describe) the sources or rationales for those statements. . . .  

The principal evidence against Parhat regarding the second and third elements of DOD’s definition of enemy combatant consists of four government intelligence documents. The documents make assertions -- often in haec verba -- about activities undertaken by ETIM, and about that organization’s relationship to al Qaida and the Taliban. The documents repeatedly describe those activities and relationships as having “reportedly” occurred, as being “said to” or “reported to” have happened, and as things that “may” be true or are “suspected of” having taken place. But in virtually every instance, the documents do not say who “reported” or “said” or “suspected” those things. Nor do they provide any of the underlying reporting upon which the documents’ bottom-line assertions are founded, nor any assessment of the reliability of that reporting. Because of those omissions, the [CSRT] could not and this court cannot assess the reliability of the assertions in the documents. And because of this deficiency, those bare assertions cannot sustain the determination that Parhat is an enemy combatant.

First, the government suggests that several of the assertions in the intelligence documents are reliable because they are made in at least three different documents. We are not persuaded. Lewis Carroll notwithstanding, the fact that the government has “said it thrice” does not make an allegation true. See LEWIS CARROLL, THE HUNTING OF THE SNARK 3 (1876) (“I have said it thrice: What I tell you three times is true.”). In fact, we have no basis for concluding that there are independent sources for the documents’ thrice-made assertions. 

Second, the government insists that the statements made in the documents are reliable because the State and Defense Departments would not have put them in intelligence documents were that not the case. This comes perilously close to suggesting that whatever the government says must be treated as true, thus rendering superfluous both the role of the Tribunal and the role that Congress assigned to this court. We do not in fact know that the departments regard the statements in those documents as reliable; the repeated insertion of qualifiers indicating that events are “reported” or “said” or “suspected” to have occurred suggests at least some skepticism. Nor do we know whether the departments rely on those documents for decisionmaking purposes in the form in which they were presented to the Tribunal, or whether they supplement them with backup documentation and reliability assessments before using them to take actions of consequence.
