Opinion En Banc

December 23, 2015- 4 - The judgments entered in the district courts are affirmed by an equally divided en banc court. See Savard v. Rhode Island, 338 F.3d 23, 25 (1st Cir. 2003) (en banc). Opinions follow.

**BARRON** , **Circuit Judge, with whom TORRUELLA and THOMPSON, Circuit Judges, join**  . Congress has long given the Attorney General discretion to decide whether to take aliens who are subject to removal into immigration custody. Congress also has long given the Attorney General discretion to decide whether to release on bond aliens who are in immigration custody while their removal proceedings are pending. Nearly thirty years ago, however, Congress began enacting a succession of similar but slightly revised immigration detention mandates that limited the Attorney General's detention discretion in certain respects. These consolidated appeals require us to decide the scope of the present version of this detention mandate, codified in 8 U.S.C § 1226(c). Much like its precursors, this detention mandate first directs that the Attorney General shall take into custody certain "criminal aliens" -- as defined by their commission of specified offenses -- "when [they are] released" from criminal custody. And, much like its precursors, this detention mandate then bars the Attorney General from releasing certain aliens on bond once they have been placed in immigration custody. The key point of dispute- 5 - concerns the class of aliens to whom this bar to bonded release applies. We conclude that Congress intended for the present detention mandate to operate like its precursors and thus that its bar to bonded release applies only to those specified criminal aliens whom the Attorney General took into custody "when [they were] released" from criminal custody. We further conclude that the two aliens who bring these habeas petitions were not taken into immigration custody "when [they were] released" from criminal custody because they had been released from criminal custody years before their immigration custody started. As a result, we conclude that the present detention mandate does not bar either petitioner from seeking release on bond pursuant to the Attorney General's discretionary release authority. Two district courts of this Circuit reached the same conclusion in granting the petitioners the right to an individualized bond hearing at which they could seek release prior to the completion of the removal process. See Gordon v. Johnson, 991 F. Supp. 2d 258 (D. Mass. 2013); Castañeda v. Souza, 952 F. Supp. 2d 307 (D. Mass. 2013). A panel of this Circuit affirmed. See Castañeda v. Souza, 769 F.3d 32 (1st Cir. 2014). This Court then agreed to rehear the case en banc, and is now, by a vote of three to three, evenly divided. In consequence, the judgments of the district courts are affirmed, as we believe they should be- 6 - given Congress's evident intention not to deny aliens like petitioners the chance to seek bonded release, the consequential nature of the decision to deny aliens such a chance, and the reality that removal proceedings can stretch on for months or even

years.

**I.** The key parts of the Immigration and Naturalization Act are codified in 8 U.S.C. § 1226, and, in particular, two subsections of it: (a) and (c). 1 Through subsection (a), Congress gave the Attorney General broad discretion to decide whether to take into custody an alien who is in the removal process. Congress also gave the Attorney General, through that same subsection, broad discretion to release on bond those aliens whom she had placed in custody so that they would not have to be detained for the often lengthy removal process. 2

1 This authorization, located in 8 U.S.C. § 1226(a), provides: "On a warrant issued by the Attorney General, an alien may be arrested and detained pending a decision on whether the alien is to be removed from the United States. Except as provided in subsection (c) of this section and pending such decision, the Attorney General . . . may continue to detain the arrested alien . . . and . . . may release the alien on . . . bond . . . ." 2 Although the Attorney General now shares responsibilities under § 1226(a) with the Secretary of Homeland Security and the Under Secretary for Border and Transportation Security, see Homeland Security Act of 2002, Pub. L. No. 107–296, §§ 402, 441, 116 Stat. 2135, we will for convenience refer to this authority as being vested in the Attorney General.- 7 - To govern the exercise of this release power, the Attorney General issued regulations pursuant to subsection (a). These regulations authorize immigration judges (subject to review by the Board of Immigration Appeals (BIA) and ultimately the Attorney General) to make individualized bond determinations based on a detainee's flight risk and danger to the community. See 8 C.F.R. § 1236.1(c)(8), (d)(1), and (d)(3). As a result of § 1226(a) and its implementing regulations, these two petitioners, Leiticia Castañeda and Clayton Gordon, plainly may be detained for the entirety of the removal process if they are found to pose sufficient bond risks. There is a question, however, whether they must be detained for the entirety of that process regardless of the showing they could make at a bond hearing. The question arises due to the contested scope of the limited exception to § 1226(a) that is carved out by § 1226(c). The exception appears in two paragraphs of subsection (c) under the single heading, "Detention of Criminal Aliens." 3

3 Section 1226(c) provides: (c) Detention of criminal aliens (1) Custody The Attorney General shall take into custody any alien who-- (A) is inadmissible by reason of having committed any offense covered in [8 U.S.C. § 1182(a)(2)], (B) is deportable by reason of having committed any offense covered in [8 U.S.C. § 1227(a)(2)(A)(ii)- (iii),(B)-(D)],- 8 - Together, the paragraphs establish the latest version of a detention mandate Congress first enacted in 1988. Illegal Immigration Reform and Immigrant Responsibility Act of 1996 (IIRIRA), tit. 111 § 303, Pub. L. No. 104-208, 110 Stat. 3009-546, 3009-585. In each prior version, Congress required first that the Attorney General "shall take into [immigration] custody any alien convicted" of an enumerated felony offense "upon completion" of the alien's sentence (1988 mandate) or "upon [the alien's] release" from criminal custody (later mandates). And, in each prior version, Congress then required that the Attorney General "shall not release such felon from [immigration] custody." See Anti-Drug Abuse Amendments Act of 1988, § 7343(a), Pub. L. No. 100-690, 102 Stat. 4181, 4470; Immigration Act of 1990, § 504(a), Pub. L. No. 101-649, 104 Stat. 4978, 5049-50; Antiterrorism and Effective

(C) is deportable under [8 U.S.C. § 1227(a)(2)(A)(i)] on the basis of an offense for which the alien has been sentenced to a term of imprisonment of at least 1 year, or (D) is inadmissible under [8 U.S.C. § 1182(a)(3)(B)] or deportable under [8 U.S.C. § 1227(a)(4)(B)], when the alien is released, without regard to whether the alien is released on parole, supervised release, or probation, and without regard to whether the alien may be arrested or imprisoned again for the same offense. (2) Release The Attorney General may release an alien described in paragraph (1) only if . . . release of the alien from custody is necessary to provide protection to a witness . . . .- 9 - Death Penalty Act of 1996 (AEDPA), § 440(c), Pub. L. No. 104-132, 110 Stat. 1214, 1277. The version of the detention mandate that is at issue here was enacted in 1996 and follows this same structure. The first paragraph, identified as § 1226(c)(1), appears under the heading "Custody." Like the portion of the earlier enacted detention mandates that contained the "upon completion" or "upon release" clauses, this paragraph sets forth the following custody directive: the Attorney General "shall take into [immigration] custody" an alien who has committed certain offenses or engaged in certain concerning behavior -- specified in subparagraphs (A)-(D) of (c)(1) -- "when the alien is released, without regard to whether the alien is released on parole, supervised release, or probation

. . . ." 4

4 As these petitioners were released from prison sentences, there is no question they were "released" within the meaning of § 1226(c)(1). With respect to the precise requirement the word "released" imposes, the Second Circuit recently held in Lora v. Shanahan that a convicted alien who receives a non-carceral sentence has also been "released." Lora v. Shanahan, 2015 WL 6499951, at *6 (2d Cir. Oct. 28, 2015). The Second Circuit concluded that this interpretation of "released" "avoids nullifying" the trailing language in (c)(1), which, through its reference to "probation," "clearly contemplates non-carceral sentences." Id. In effect, the Second Circuit interprets "released" to mean "release from the technical custody of the criminal court" (i.e., at the end of the sentencing proceeding), a position that the government has elsewhere advanced. See In re West, 22 I. & N. Dec. 1405, 1408 (BIA 2000). In so doing, the Second Circuit did not address the BIA's view that "released" means even release from pre-conviction arrest. See In re Kotliar, 24 I.- 10 - The second paragraph, identified as § 1226(c)(2), follows directly after (c)(1) and appears under the heading "Release." Like the portion of the earlier enacted detention mandates that contained the "such felon" clause, this paragraph sets forth the following bar to bonded release from immigration custody: the Attorney General "may release an alien described in paragraph (1) only if" the alien satisfies certain limited criteria not at issue here. 5 Under petitioners' view, (c)(1) and (c)(2) operate in tandem just as the earlier detention mandates did. In consequence of the words "when" and "released" in the first paragraph, the Attorney General must timely take specified aliens coming out of criminal custody into immigration custody. The second paragraph, by referring to the prior paragraph, then requires the Attorney General not to release on bond the specified aliens that she has timely taken into immigration custody following their release from criminal custody in accordance with the directive in (c)(1).

& N. Dec. 124, 125 (BIA 2007); West, 22 I. & N. Dec. at 1410; see also Saysana, 590 F.3d at 14 (suggesting, more broadly, that an alien could be arrested and not convicted and yet still fall within § 1226). 5 Aliens taken into custody pursuant to § 1226(c) are entitled to a "Joseph" hearing at which the alien "may avoid mandatory detention by demonstrating that he is not an alien, was not convicted of the predicate crime, or that [U.S. Immigrations and Customs Enforcement] is otherwise substantially unlikely to establish that he is in fact subject to mandatory detention." Demore v. Kim, 538 U.S. 510, 514 n.3 (2003).- 11 - Petitioners contend that this reading of § 1226(c) makes sense not only as a matter of text, structure, and history, but also on its own terms. Petitioners point to the substantive differences between aliens taken into immigration custody "when . . . released" from criminal custody and those aliens who are taken into immigration custody some time after they have been "released" from criminal custody. Petitioners emphasize that "the experience of having one's liberty stripped away is drastically different from the experience of not having it restored." See Castañeda v. Souza, 952 F. Supp. 2d 307, 318 n.10 (D. Mass. 2013). They also note that their intervening period of freedom makes it possible to take account of their post-release conduct in evaluating the flight risk or danger they may pose. 6 And amici contend that Congress had practical reasons to limit the scope of the mandate in this way, given resource constraints on detention capacity. See Amicus Br. of Frm. Imm. Judges and DHS Sec. Officials at 17-20. On the basis of this reading of § 1226(c), petitioners contend that the exception to § 1226(a) that (c) carves out does not apply to them due to the remoteness of their release from

6 For example, since his release from criminal custody in 2008, petitioner Clayton Gordon has become a father, bought a house, developed a successful business, and worked on a project to open up a halfway house for women. Castañeda, 769 F.3d at 40.- 12 - criminal custody. 7 Accordingly, petitioners argue they may seek discretionary release on bond under (a) just like any other alien placed in custody by the Attorney General pursuant to that subsection. The government counters that petitioners' argument fails at the threshold on the basis of the interpretation of § 1226(c)(2) that the BIA set forth in In re Rojas, 23 I. & N. Dec. 117 (BIA 2001). The BIA held in Rojas that only subparagraphs (A)-(D) of (c)(1) (which enumerate predicate offenses and other qualifying misconduct) limit (c)(2). Rojas thus makes the rest of (c)(1) -- including the "when . . . released" clause and its trailing language specifying what counts as a "release[]" from criminal custody -- irrelevant to the application of (c)(2). See Rojas, 23 I. & N. Dec. at 121 ("The 'when released' clause is no more a part of the description of an alien who is subject to detention than are the other concluding clauses." (emphasis in original)).

7 Leiticia Castaneda, a native of Brazil, was arrested in Massachusetts for misdemeanor possession of cocaine, sentenced to probation, and released from custody in 2008. Castañeda, 769 F.3d at 39. Clayton Gordon, a nati ve of Jamaica, was arrested in Connecticut for possession of cocaine with intent to distribute and was thereupon released from custody in 2008. Id. at 40. Gordon subsequently pled guilty and received a suspended prison sentence and three-year probationary term in 2009. More than four years after their respective releases from criminal custody, the government took each of the petitioners into immigration custody and charged them with removal due to their convictions. Id.- 13 - The government contends we must defer to Rojas's conclusion that whatever limitations the words "when" and "released" impose on § 1226(c)(1) do not matter for (c)(2) because the text of (c)(2) is not clear on that key point. The government claims we must do so because Rojas reasonably construed (c)(2) to reduce the chance that an alien with an (A)-(D) offense might be released due to a mistaken evaluation of bond risk. The government therefore argues that Rojas requires petitioners' mandatory detention without bond -- notwithstanding their years of living freely -- because each petitioner committed an (A)-(D) offense and nothing more is required for (c)(2) to apply. In the alternative, the government asserts that even if Rojas is wrong and the "when . . . released" clause is relevant to (c)(2), the petitioners were in fact taken into immigration custody "when . . . released." The government argues that the word "when" is best read in context to mean "if" or "any time after." As a fallback, the government argues that the word "when" at most triggers a duty to act promptly that persists indefinitely. Either way, the government argues, § 1226(c)(2) applies to aliens with predicate offenses who were taken into immigration custody even years after their release from criminal custody. 8

8 After the panel ruled for the petitioners, the government scheduled bond hearings for each one. Before Castañeda's bond hearing took place, the government, of its own accord, concluded- 14 - We consider each argument in turn. We explain first why we conclude that the "when . . . released" clause in § 1226(c)(1) also modifies the scope of (c)(2). We then explain why we conclude

that the "when . . . released" clause imposes a deadline for picking up an alien coming out of criminal custody that limits the application of (c)(2)'s bar to bonded release. 9

**II.** We start with the question whether we must defer to Rojas's reading of § 1226(c)(2), under which the "when . . . released" clause in (c)(1) is wholly irrelevant to the scope of (c)(2). In undertaking this inquiry, we apply the two-

that she did not pose a flight risk or a danger to the community and released her. Gordon, by contrast, made his case to an immigration judge at a bond hearing, prevailed, and was released as well. These decisions to release the petitioners do not render the present appeal moot. See Sylvain v. Attorney Gen. of U.S., 714 F.3d 150, 161 n.12 (3d Cir. 2013). 9 Four other circuits have addressed the issues we address here. In Hosh v. Lucero, 680 F.3d 375, 378-381 (4th Cir. 2012), the Fourth Circuit claimed to defer to Rojas. But, contra Rojas, Hosh actually assumed the "when . . . released" clause limited§ 1226(c)(2) and concluded that the word "when" is not timelimited -- a view that the BIA has never adopted. In Sylvain v. Attorney Gen. of U.S., 714 F.3d 150, 161 (3d Cir. 2013), the Third Circuit avoided deciding the meaning of "an alien described inparagraph (1)" by holding for the government on the basis of lossof-authority principles. More recently, in Olmos v. Holder, 780 F.3d 1313, 1324 (10th Cir. 2015), the Tenth Circuit deferred to Rojas, as did the Second Circuit in in Lora, 2015 WL 6499951, at *6. Numerous district courts have addressed the issue, and most have gone the other way. See Immig. Law Profs. et al. Amicus Br. at A-xxii-xxix (assembling eighty-nine cases that have rejected Rojas).- 15 - step test set forth in Chevron, U.S.A., Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837 (1984). At step one, we must decide whether Congress spoke clearly to the precise question at issue. Id. at 842. If so, that ends the matter. Id. at 842-43. If not, then, at step two, we must defer to the administering agency's interpretation if it is reasonable. Id. at 843. Our focus is on step one, which is where we conclude Rojas went wrong. 10 For while Chevron is a famous doctrine, much precedent cautions us not to be so star-struck by it that we must defer to the agency at the first sign of uncertainty about the meaning of the words that Congress chose. Rather, under Chevron, we must be mindful that "a statute may foreclose an agency's preferred interpretation despite such textual ambiguities if its structure, legislative history, or purpose makes clear what its text leaves opaque." See Council for Urological Interests v. Burwell, 790 F.3d 212, 221 (D.C. Cir. 2015) (quoting Catawba Cnty.,

10 The line between step one and step two of the Chevron analysis is not always clear. See Saysana v. Gillen, 590 F. 3d 7, 13-18 (1st Cir. 2009) (in declining to defer to the BIA's interpretation of § 1226(c), the court relied on both step one and step two); Patricia M. Wald, Judicial Review in Midpassage: The Uneasy Partnership Between Courts and Agencies Plays On, 32 Tulsa L.J. 221, 243 (1996) (noting that whether a case is decided at step one depends on "how judges identify the precise question at issue, since at one level of generality the statute may answer it under Chevron step one, but at [another] level there may be an ambiguity"). Because we conclude that Congress spoke clearly to the relationship between § 1226(c)(1) and (c)(2), and because the precise issue Rojas decided concerned that relationship, we resolve this issue under step one.- 16 - N.C. v. E.P.A, 571 F.3d 20, 35 (D.C. Cir. 2009)); see also Chemical Manufacturers Ass'n v. N.R.D.C., 470 U.S. 116, 126 (1984) ("We should defer to [the administering agency's view of the statutory language] unless the legislative history or the purpose and structure of the statute clearly reveal a contrary intent."). And that is the case here. In light of both the Act's structure, see F.D.A. v. Brown & Williamson Tobacco Co., 529 U.S. 120, 132-34 (2000) (analyzing the words of a statute in view of the "overall statutory scheme" at Chevron step one); Saysana, 590 F.3d at 13-15 (emphasizing the structure of § 1226(c) in declining to defer to the BIA's interpretation by noting that "the 'plain meaning' of a statutory provision is often made clear not only by the words of the statute but by its structure"), and the legislative history, see I.N.S. v. Cardoza-Fonseca, 480 U.S. 421, 448-49 (1987) (considering legislative history at step one of the Chevron analysis in declining to defer to Immigration and Naturalization Service (INS) interpretation of statute); Succar v. Ashcroft, 394 F.3d 8, 31 (1st Cir. 2005) ("Our view is that where traditional doctrines of statutory interpretation have permitted use of legislative history, its use is permissible and even may be required at stage one of Chevron."), we conclude that Congress plainly intended for the "when . . . released" clause in (c)(1) to apply to (c)(2) as well.- 17 - **A.** Rojas identified a clear choice between two possible readings of the words in the cross-reference in § 1226(c)(2), "an alien described in paragraph (1)." See Rojas, 23 I. & N. Dec. at 119. Given the text of the cross-reference, the alien to whom (c)(2) refers is either (as Rojas held) an alien who has committed an offense specified in subparagraphs (A)-(D) of (c)(1) or (as petitioners contend) an alien who was taken into custody pursuant to the duty imposed by paragraph (1) as a whole. This choice matters because it determines whether the "when . . . released" clause -- and whatever limits it imposes through the words "when" and "released" -- modifies the scope of § 1226(c)(2). If "an alien described in paragraph (1)" refers to an alien who was taken into custody pursuant to the duty imposed by (c)(1) as a whole, then the cross-reference would not merely refer to an alien who has committed an (A)-(D) offense. It would instead refer to an alien who has committed an (A)-(D) offense and whom the Attorney General took into immigration custody "when" the alien was "released" from criminal custody, as the "when . . . released" clause sets forth the conditions under which that duty applies. Rojas, 23 I. & N. Dec. at 121-22. And (c)(2), then, would come into play as a bar to the release of only those aliens picked up after the duty in (c)(1) had been discharged. See id. at 119 (noting that the cross-reference in (c)(2) could be- 18 - read to "refer[] to an alien who is taken into [immigration custody] 'when the alien is released'"). In our view, the words "an alien described in paragraph (1)" comfortably support petitioners' reading. Consistent with the ordinary meaning of the word "described," § 1226(c)(2) refers to a "mental image, an impression, or an understanding of the nature and characteristics," see Webster's Third New International Dictionary 610 (2002), of the alien whom (c)(1) as a whole calls to mind. And thus "an alien described in paragraph (1)" refers to an alien who has committed an enumerated offense and whom the Attorney General has taken into immigration custody "when . . . released" from criminal custody. See also The American Heritage Dictionary of the English Language 476 (5th ed. 2011) (defining "describe" as "[t]o convey an idea or impression of" or "[t]o trace the form or outline of"). No rule of grammar counsels against this reading. Antecedents to cross-references may be found in verbal and adverbial phrases in prior paragraphs not just because (as our colleagues suggest) users of English sometimes use language awkwardly. Antecedents to cross-references may be found in such places because people also use language efficiently. 11

11 According to linguists, "probably the most important thing to understand" about antecedents "is that [antecedents] are not the elements in the text but are those suggested by it, those- 19 - One thus commits no offense against the English language by saying that the narrator "described in" Frost's famous poem is the one who "took the road less travelled," even though the narrator's first-person account of his past actions in the poem is not cast in what our colleagues would consider inherently descriptive terms. And, in fact, Congress has itself relied on the "described in paragraph (1)" formulation to refer not just to the inherently descriptive adjectival portion of the prior paragraph but to the adverbial portion , too. See 28 U.S.C § 1441(c)(1)-(2) (in referring to an "action described in paragraph (1)," Congress clearly intended to capture the trailing adverbial portion of paragraph (1), which states that the "entire action may be removed if the action would [otherwise] be removable"). The petitioners' reading finds additional support in the fact that the text of the cross-reference does not expressly state, as one might have expected if Rojas were right, that the only part of § 1226(c)(1) that is relevant to (c)(2) is the part that

See IIRIRA § 303(b)(3), 110 Stat. 3009- 587 ("The Attorney General may release the alien only if the alien is an alien described in subparagraph (A)(ii) or (A)(iii)." (emphasis added)). Nevertheless, we agree that, standing alone, the words "an alien described in paragraph (1)" could be read as Rojas reads them. As a textual matter, the "described in" language in the cross-reference could be read to refer the reader only to subparagraphs (A)-(D) of paragraph (1), as they plainly do describe the alien in (c)(1). One could thus read this cross-reference as

12 Our colleagues argue that Rojas 's reading is reinforced by the fact that the "when . . . released" clause is not aligned with subparagraphs (A)-(D), as if the indentation means to tell the reader of the cross-reference in § 1226(c)(2) where to look in (c)(1) for the antecedent. See infra at 72-73. But we do not see how that form of presentation has any helpful bearing on the meaning of (c)(2)'s cross-reference. The limits imposed by the unindented language, including the "when . . . released" clause, affect all aliens who come within the scope of (c)(1). The predicate offenses identified in the indented subparagraphs, by contrast, serve as independent triggers. The alignment thus flows from the structure of (c)(1) without regard to the cross-reference in the follow-on paragraph and thus offers little support for Rojas's reading of that cross-reference.- 21 - directing the reader to identify the alien whom (c)(1) itself refers to in characteristically descriptive terms, rather than directing the reader to identify the alien whom (c)(1) as a whole calls to mind. 13 To determine if Congress chose between the two possible antecedents to the cross-reference in § 1226(c)(2), we thus must do what Rojas did: look beyond the words of the cross-reference. See Rojas, 23 I. & N. Dec. at 121-24 (reviewing the structure of the act in which § 1226 appears and its legislative history, as well as the predecessor provisions to § 1226). And it makes particular sense to do so here, as there is good reason to question whether Congress would have intended to leave the precise issue unresolved. To find that Congress did not intend to choose an antecedent, one would have to believe Congress was content to let the very executive branch officials that it did not trust to

13 Our colleagues suggest that the Supreme Court has interpreted § 1226(c) as Rojas did, infra at 74-75, in Demore, 538 U.S. at 513. But although the Supreme Court cited (c) as a whole in the first sentence of its opinion, the Court then went on to quote in that sentence the leading language of (c)(1) -- "[t]he Attorney General shall take into custody any alien who" -- without referencing (implicitly or otherwise) any of the language in (c)(2). Our colleagues do not -- and cannot -- argue that the "when . . . released" clause is irrelevant to even (c)(1). We thus do not see how the Court's failure to refer expressly to a clause that obviously applies to (c)(1) in its fly-by paraphrasing of (c)(1) could possibly be said to provide support for the government's view of the particular issue we must decide, which is the relationship between (c)(1) and (c)(2). And that is particularly true as the relationship between the two paragraphs was not even at issue in Demore.- 22 - make certain detention decisions determine the extent of that distrust through their choice between the two possible antecedents. See American Bar Ass'n v. F.T.C., 430 F.3d 457, 469 (D.C. Cir. 2005) (noting that "the sort of ambiguity giving rise to Chevron deference is a creature not of definitional possibilities, but of statutory context" and declining to defer to an agency's interpretation given the sort of ambiguity at issue (quotation marks and citation omitted)). Accordingly, before we conclude that Congress did not speak to this issue, we need to consider the relevant words in context, as is required under Chevron step one.

**B.** A key part of that context is the structure of the IIRIRA as a whole, as we are obliged to construe § 1226(c) in light of the whole act in which that provision appears. See Whitman v. Am. Trucking Ass'ns, 531 U.S. 457, 484 (2001). The structure of that act, however, is hard to square with Rojas. And thus the structure of the IIRIRA supports the conclusion that Congress chose to refer to an alien "described in paragraph (1)" rather than more specifically to an alien "des cribed in subparagraphs (A)-(D)" because Congress intended to refer to an alien called to mind by the paragraph as a whole. We start first with the structure of § 1226, which is oddly misaligned unless we look beyond subparagraphs (A)-(D) of- 23 - (c)(1) to the "when . . . released" clause to identify the alien to whom (c)(2) refers. Cf. Whitman, 531 U.S. at 484-86 (declining to defer to an agency's interpretation under Chevron where such interpretation was "so at odds with [the statute's] structure," in that it rendered certain parts of a carefully delimited exception to the agency's otherwise broad discretion "nugatory"). Themisalignment arises because Rojas necessarily reads the crossreference to de-link the "Custody" directive in § 1226(c)(1) from the bar to "Release" in (c)(2). Rojas has this effect because, for example, as the government has previously informed us, "there are a variety of offenses for which an alien may be . . . subject to mandatory detention under [§ 1226(c)(1)(A)], but that may never give rise to a formal charge, let alone an indictment, trial or conviction." See Saysana, 590 F.3d at 14 (quotation marks omitted) (restating the government's argument). 14 In consequence, some aliens who fall within subparagraphs (A)-(D) will not be subject to (c)(1) because they will never have even been "released" from criminal custody as the "when . . . released" clause requires. See Rojas, 23 I. & N.

14 For example, an alien may fall within § 1226(c)(1)(A) after receiving a summons and paying a fine for marijuana possession. See Immig. Law Profs. et al. Amicus Br. at 5-6. In addition, aliens defined in § 1226(c)(1)(D) are inadmissible or deportable solely for having engaged in certain terrorist conduct, and so criminal custody is not a necessary precondition to qualifying as a (D)-type alien.- 24 - Dec. at 122. 15 According to Rojas, however, such aliens -- if taken into custody pursuant to § 1226(a) -- would still be subject to the bar to bonded release that (c)(2) establishes. Rojas necessarily would apply the bar to bonded release to such aliens because Rojas makes an alien's "release" from criminal custody irrelevant to the application of § 1226(c)(2). After all, it is the "when . . . released" clause and not subparagraphs (A)-(D) that ensures that an alien taken into custody pursuant to (c)(1) is an alien who has been "released" from criminal custody. Thus, Rojas incongruously (and without even acknowledging the incongruity) requires one to believe that Congress was so concerned about certain aliens who had never been in criminal custody, as the "when . . . released" clause contemplates, being out and about that it directed the Attorney General to hold them without bond even though Congress left her

15 Under any interpretation of "released," see H.R. Rep. No. 101-681(I), § 1503, at 148 (1990), reprinted in 1990 U.S.C.C.A.N. 6472, 6554, 1990 WL 188857 (stating that the trailing language in § 1226(c)(1) was intended to clarify that the Attorney General must "incarcerate aggravated felons upon release from confinement, regardless of whether such release involves parole, probation, or other forms of supervision." (emphasis added)); Lora, 2015 WL 6499951, at *6; Kotliar, 24 I. & N. Dec. at 125; West, 22 I. & N. Dec. at 1410, some aliens who fall within the definition of subparagraphs (A)-(D) will not have been "released" as they will not have been in criminal custody of any sort.- 25 - complete discretion to decide not to take them into immigration custody at all. 16 Petitioners' reading avoids this oddly half-hearted understanding of the detention mandate. Petitioners read the release-from-criminal-custody constraint that appears outside subparagraphs (A)-(D) and in the "when . . . released" clause to limit both the "Custody" and "Release" aspects of the detention mandate. Under this more natural reading, § 1226 as a whole coheres quite well. Pursuant to § 1226(a), the Attorney General would have the discretion to release on bond those aliens she had the discretion not to take into custody. And, pursuant to § 1226(c), the Attorney General would be mandated to keep in custody

16 Tellingly, there is no indication in the record or legislative history to the IIRIRA that Congress was any more worried about the release by immigration authorities of criminal aliens already in immigration custody than about the failure of immigration authorities to take criminal aliens into custody in the first place. And thus we do not see a basis for concluding that a Congress concerned about "[u]ndetained aliens," S. Rep. No. 104-48 (1995), 1995 WL 170285, at *2, would be inclined to place a release-from-criminal-custody constraint on the discretion to take aliens into immigration custody but not on the discretion to release aliens from such custody. The puzzle, then, is why Congress would have wanted to express its unhappiness with both forms of executive discretion in the partial way Rojas favors. Notably, such different treatment would apply not only to the one type of alien who has never been released from criminal custody that our colleagues choose to mention, see infra at 90, but it would also implicate myriad other types of aliens that the government itself has consistently identified as falling within subparagraphs (A)-(D) but not within the (c)(1) custody directive more broadly. See, e.g., Saysana, 590 F.3d at 14.- 26 - only those she was mandated to take into custody. 17 See Saysana, 590 F.3d at 9, 13-16 (analyzing the meaning of the "when . . . released" clause and its trailing language in (c)(1) in order to determine whether an alien was properly held without bond under (c)(2)). In this way, Congress would have crafted a detention mandate that, from start to finish, covers the same class of aliens (whatever the word "when" might mean) that it had identified as a

cause for concern. 18 Two other parts of the IIRIRA lend further support to petitioners' reading of the cross-reference, in which the "when . . . released" clause in (c)(1) applies as a constraint

17 Our colleagues note that the description in § 1226(c)(2) of when aliens subject to that provision may qualify for release from immigration custody -- when necessary for witness protection -- does not refer expressly to the "when . . . released" clause. See infra at 74. But ( c)(2) also does not expressly refer to subparagraphs (A)-(D), yet our colleagues would not dispute that a person with no such predicate offense could not be subject to (c)(2). We thus do not believe this exception clarifies the precise issue at hand in any respect. 18 In describing the "mand atory detention provision" (i.e., § 1226(c)), the panel in Saysana concluded that "the 'when released' language serves th[e] . . . limited but focused purpose of preventing the return to the community of those released in connection with the enumerated offenses [in subparagraphs (A)- (D)] . . . ." 590 F.3d at 17 (emphasis added). Saysana thus viewed the "when . . . released" clause as limiting (c) as a whole, including the piece of (c) that "prevents the return to the community" (i.e., prohibits the bonded release) of certain aliens. See also Matter of García-Arreola, 25 I. & N. Dec. 267, 270-71 & n.4 (BIA 2010) (concluding that Saysana held that (c)(2) refers to and incorporates the "when . . . released" clause as a constraint and thereby recognizing the conflict between Saysana and Rojas).- 27 - across the whole of (c). These parts of the IIRIRA are set forth in the Transition Period Custody Rules (TPCR). These rules apply instead of § 1226(c) for a one- or two-year transition period, but only if they are invoked by the Attorney General. IIRIRA § 303(b)(2), Pub. L. No. 104-208, 110 Stat. at 3009-586. The first instructive part lies in the TPCR's parallel detention mandate. The TPCR's mandate shares the same structure as § 1226(c). 19 And, notably, like § 1226(c), the predicate

19 The TPCR, enacted in IIRIRA § 303(b)(3), Pub. L. No. 104- 208, 110 Stat. at 3009-587, provides in part: (A) IN GENERAL. -- During the period in which this paragraph is in effect pursuant to paragraph (2), the Attorney General shall take into custody any alien who -- (i) has been convicted of an aggravated felony . . . , (ii) is inadmissible by reason of . . . , (iii) is deportable by reason of having committed any offense covered in . . . , or (iv) is inadmissible under . . . , when the alien is released, without regard to whether the alien is released on parole, supervised release, or probation, and without regard to whether the alien may be arrested or imprisoned again for the same offense. (B) RELEASE. -- The Attorney General may release the alien only if the alien is an alien described in subparagraph (A)(ii) or (A)(iii) and-- (i) the alien was lawfully admitted to the United States and satisfies the Attorney General that the alien will not pose a danger to the safety of other persons or of property and is likely to appear for any scheduled proceeding, or (ii) the alien was not lawfully admitted to the United States, cannot be removed because the designated country of removal will not accept the alien, and satisfies the Attorney General that the alien will not pose a danger to the safety of other persons or of property and is likely to appear for any scheduled proceeding.- 28 - offenses that trigger the custody directive in the TPCR do not require an alien to have been "released" from criminal custody. See Matter of Garvin-Noble, 21 I. & N. Dec. 672, 680-81 (BIA 1997). The TPCR's mandate thus presents the same interpretive question that § 1226(c) presents as to whether the "when . . . released" clause -- and thus its release-from-criminal-custody constraint -- in that mandate's custody directive limits that mandate's followon bar to bonded release. And because this mandate presents the same interpretive question, it also presents the same potential structural misalignment. 20 Tellingly, the TPCR presents its custody directive (including its "when . . . released" clause) under the heading "In General" and the bar to bonded release under the subsequent heading, "Release." This presentation indicates that the "when . . . released" clause constrains both the custody directive and the bar to bonded release, such that the bar applies to the very people encompassed by the "General" directive, rather than to some people who were not encompassed by that directive at all because they were never "released" from criminal custody.

20 The two paragraphs in the transition rules are linked by a cross-reference ("the alien") that differs from the one our colleagues mistakenly assign such weight in construing § 1226(c)(2) and that is, as a purely textual matter, also not clear.- 29 - The second instructive part of the IIRIRA lies in section 303(b)(2), Pub. L. No. 104-208, 110 Stat. at 3009-586. This TPCR provision mediates the shift from the transition rules to the permanent regime. The provision clearly provides that § 1226(c) as a whole -- both with respect to its custody directive and its bar to bonded release -- applies only to aliens "released after" the TPCR expires. And the BIA has rightly read this "released after" clause to mean that an alien must have been "released" from criminal custody to be subject to § 1226(c) going forward. See In re Adeniji, 22 I. & N. Dec. 1102, 1108-11 (BIA 1999). This clause thus ensures that a release-from-criminal-custody constraint does now limit the scope of both (c)(1) and (c)(2). If we applied Rojas's analysis of (c)(2) to the TPCR's equivalent to (c)(2), however, no such "released" constraint would limit the scope of that portion of the TCPR's detention mandate because the "when . . . released" clause in its custody directive would not apply to the mandate as a whole. Under Rojas, therefore, the "released after" clause would -- in this key respect -- make the permanent mandate's bar to bonded release less sweeping than the supposedly more flexible TPCR mandate's bar had been, even though Congress clearly intended the latter to be less- 30 - encompassing. 21 No such anomalous narrowing of the detention mandate would occur upon the expiration of the TPCR if, by contrast, the "when . . . released" clause limits the bar to bonded release that appears in both the transition and the permanent

rules. 22 For these reasons, the structure of the IIRIRA as a wholestrongly indicates that Congress did intend for the crossreference in § 1226(c)(2) to reach beyond subparagraphs (A)-(D) to the "when . . . released" clause and thus to refer to an alien taken into custody pursuant to the duty imposed by (c)(1) as a

whole. 23 And thus the IIRIRA's structure indicates that Congress

21 See 142 Cong. Rec. S11838-01, 1996 WL 553814 (daily ed. Sept. 30, 1996) (statement of Sen. Hatch) (explaining that one of the IIRIRA's managers and conferees agreed to the TPCR because of the INS's pleas of insufficient resources to comply with the AEDPA); Garvin-Noble, 21 I. & N. Dec. at 675 (same). 22 Our colleagues try to d ownplay this anomaly by emphasizing the carve-outs in the TPCR's bar to bonded release. See infra at 88-89. But these carve-outs are limited ones. IIRIRA § 303(b)(3)(B), Pub. L. No. 104-208, 110 Stat. at 3009-587. And we think it unlikely that Congress would have intended for only the detention mandate in the transition regime -- and not the detention mandate in the permanent regime -- to apply to some aliens in such classes of potentially dangerous criminal aliens as unlawfully admitted aliens with a § 1226(c)(1)(A) predicate and aliens with a § 1226(c)(1)(D) predicate. It is especially unlikely that Congress would have intended the TPCR, but not § 1226(c), to operate without a release-from-criminal-custody constraint on its detention mandate when the preceding detention mandate did embody such a constraint. See AEDPA, § 440(c), Pub. L. No. 104-132, 110 Stat. 1214, 1277; see Grodzki v. Reno, 950 F. Supp. 339, 342 (N.D. Ga. 1996). 23 The "released after" clause would minimize the strange disjuncture between § 1226(c)(1) and (c)(2) that Rojas unavoidably- 31 - referred to paragraph (1) rather than more specifically to the subparagraphs within in it because Congress intended to link the "Custody" and "Release" aspects of the detention mandate so that they would work together. Before we conclude that Congress clearly chose the broader antecedent to "an alien described in paragraph (1)," however, we must still "exhaust the traditional tools of statutory construction." See Sierra Club v. EPA, 551 F.3d 1019, 1027 (D.C. Cir. 2008). And so we now turn to the legislative history.

**C.** The legislative history confirms that Congress intended the cross-reference in § 1226(c)(2) to refer to an alien taken into custody pursuant to the duty imposed by (c)(1) as a whole

creates, but we presume the coherence of the permanent detention mandate was not intended to depend on the triggering of an ancillary and potentially never operative clause in the TPCR. Whitman, 531 U.S. at 468. Regardless, the "released after" clause would do nothing to avoid the anomaly of the permanent mandate being less sweeping in a key respect than the transition mandate had been. Our colleagues, but not the government or Rojas itself, contend that the canon against surplusage supports Rojas's reading of the cross-reference in § 1226(c)(2) because otherwise "when . . . released" would be duplicative of "released after." See infra at 75-76. But to the extent this argument has any force, it has it only if "when" has a time-limited meaning. The surplusage concern thus provides no basis for concluding that Rojas is right to treat the "when . . . released" clause as a whole as irrelevant to (c)(2). As a result, we consider this surplusage argument when we turn to the issue of what "when" means -- an issue on which we owe the BIA no deference and which we must confront only if the "when . . . released" clause does apply to all of (c).- 32 - rather than only to an alien described in subparagraphs (A)-(D). And thus the legislative history helps to make clear that the "when . . . released" clause -- and whatever limitations it imposes -- applies across the whole of (c). This conclusion follows from the legislative history directly tied to the IIRIRA and from the many precursors to § 1226(c). The text and history of those precursors show that Congress intended for those versions of the detention mandate to operate in just the linked manner that Rojas rejects in construing (c), and the evidence also indicates that Congress did not mean to alter this aspect of the longstanding scheme in passing the IIRIRA. Milner v. Department of the Navy, 562 U.S. 562, 572 (2011) ("Those of us who make use of legislative history believe that clear evidence of congressional intent may illuminate ambiguous text."); see also Goldings v. Winn, 383 F.3d 17, 21 (1st Cir. 2004) ("[I]f the statute's legislative history reveals an unequivocal answer as to the statute's meaning, we do not look to the [agency's] interpretation . . . .").

**1.** The title to § 1226(c) -- encompassing both (c)(1)'s "Custody" directive and (c)(2)'s "Release" bar -- is "Detention of Criminal Aliens." The conference report to the IIRIRA follows the language of that overarching title in describing in unqualified terms the "subsection" as providing that the Attorney General "must- 33 - detain" certain aliens. The report then sets forth one qualification to that requirement in the next sentence and another qualification in the third sentence, stating that "[t]his detention mandate applies whenever such an alien is released from imprisonment, regardless of the circumstances of the release." H.R. Conf. Rep. No. 104-828 (1996), 1996 WL 563320, at *210-11. And finally, the report states that "[t]his subsection also provides" for the "release[]" of aliens "from the Attorney General's custody" in one limited circumstance. See id. In keeping with the title to § 1226(c), we thus understand the useof the phrase "[t]his detention mandate" to refer to a start-tofinish detention regime that is limited across-the-board by the "when . . . released" clause. See Rojas, 23 I. & N. Dec. at 119, 122-23 (describing the "mandatory detention aspects of the statute" as arising from both the bar to bonded release and the custody directive). After all, the report expressly attributes the mandate to the "subsection" it describes rather than to only part of it. But even if, as our colleagues contend, the report's reference to "[t]his detention mandate" is only to the differently worded and more limited duty to "take into custody" certain aliens set forth only in § 1226(c)(1), see infra at 77-78, the report would then merely restate the question that we must decide: whether Congress intended for the bar to bonded release set forth in (c)(2)- 34 - to incorporate the conditions that plainly limit the application of the custody directive in (c)(1). 24 If so, the remaining legislative history that actually concerns the relationship between the custody and release aspects of the detention mandate convinces us that Congress clearly did so intend, when this history is read against the strong structural reasons to conclude that Congress chose to refer in (c)(2) to "paragraph (1)" rather than subparagraphs (A)-(D) in order to encompass the same aliens under both (c)(1) and (c)(2). Just prior to conference, a leading Senate sponsor of the IIRIRA described the bill as "ensur[ing] that aliens who commit serious crimes are detained upon their release from prison until they can be deported . . . ." 142 Cong. Rec. S10572-01 (daily ed. Sept. 16, 1996), 1996 WL 522794 (statement of Sen. Simpson) (emphasis added). And it should be no surprise that Senator

24 Our colleagues' reading of the fourth sentence of the report, see infra at 77-78, takes "the Attorney General's custody" referenced in that sentence to be any custody, even if effected as a matter of discretion under § 1226(a), rather than to be the mandatory custody of the Attorney General under § 1226(c) that -- on our colleagues' reading of the report -- the preceding sentences had necessarily just referenced. And our colleagues read the reference to "such an alien" in that sentence to be a reference only to an alien who has committed an (A)-(D) offense rather than to an alien who was taken into custody pursuant to the duty imposed by (c)(1) as a whole. See id. But the text does not resolve whether our colleagues are right to read these words this way, as these words on their own do not tell us whether the report treats the "when . . . released" clause as if it were incorporated as a limitation on the bar to bonded release.- 35 - Simpson described the bill this way. Congress stated in a key report right before conference that the new measure was intended to "restate[]" the provisions of the old statute "regarding the detention of an alien convicted of an aggravated felony . . . ." See H.R. Rep. 104-469(I) (1996), 1996 WL 168955, at *230. And, as we next explain, each prior version of the detention mandate (including the immediate precursor to the IIRIRA) similarly treated the two analogous directives to the ones that subsection (c) contains as operating in tandem.

**2.** The text and legislative history to the precursors to § 1226(c) clearly show that Congress intended to link the custody directive and the bar to bonded release in these prior detention mandates in just the way that Rojas rejects in construing § 1226(c). And interpreters of those precursors –- including both the BIA and the district courts –- so read them. We start with the 1988 mandatory detention statute, which provided: "The Attorney General shall take into custody any alien convicted of an aggravated felony upon completion of the alien's sentence for such conviction. Notwithstanding subsection (a) [the then-equivalent of § 1226(a)], the Attorney General shall not release such felon from custody." Anti-Drug Abuse Act of 1988, § 7343(a), Pub. L. No. 100-690, 102 Stat. 4470. The text is most naturally read as limiting the bar to bonded release to the- 36 - "felons" whom the Attorney General was required to "take into custody." And not long after its enactment, the BIA read the provision just that way, by treating the "upon completion" clause (the then-equivalent of the "when . . . released" clause) in the 1988 mandate's custody directive as if it conditioned that mandate's "such felon" clause (the then-equivalent of "an alien described in paragraph (1)") in the follow-on bar to bonded release from immigration custody. Matter of Eden, 20 I. & N. Dec. 209, 211 (BIA 1990). 25

25 The BIA's decision in Eden, as our colleagues point out, did not involve the particular timing element involved in this case. But that is no matter as Eden is directly on point as to the precise issue for which the government seeks Chevron deference -- that is, the relationship between the "custody" and "release" aspects of the present detention mandate. Our colleagues contend otherwise as follows. Our colleagues suggest that even if the BIA in Eden had reached the same result by concluding, instead, that once an aggravated felon was in immigration custody he could not then be released on bond (regardless of whether he had ever been released from criminal custody), the BIA still would have had reason to consider the meaning of the "upon completion" clause. And that is because, our colleagues contend, the BIA would have had an interest in clarifying whether the Attorney General had the authority to place an alien in immigration custody at all, even discretionarily, while that alien was still serving his criminal sentence. See infra at 93-94. But the BIA had no need to clarify the meaning of the "upon completion" clause for that distinct purpose. And that is because, as the BIA in Eden acknowledged, an alien could have been taken into immigration custody under the discretionary detention authority conferred by then-equivalent to § 1226(a). In fact, the immigration judge in Eden granteddiscretionary bond to the alien in that case under the thenequivalent of § 1226(a), which occasioned the appeal to the BIA by the executive. See Eden, 20 I. & N. Dec . at 210, 212 (noting that the immigration judge had concluded that the alien "had been properly detained under [the then-equivalent of § 1226(a)]" and- 37 - The 1990 amendments to the 1988 statute then codified Eden, which was decided months earlier, and the House report to the amendments espoused that same view of the relationship between the two clauses. That report characterized "current law" (that is, the detention mandate set forth in the 1988 statute) as "requir[ing] [the government] to incarcerate alien aggravated felons without bond immediately upon completion of the alien's criminal 'sentence.'" H.R. Rep. No. 101-681(I), § 1503, at 148 (1990) (emphasis added); cf. United States v. Bd. of Comm'rs of Sheffield, Ala., 435 U.S. 110, 129-35 (1978).Moreover, in codifying Eden, Congress modified the thenequivalent of § 1226(c)(1) in order to clarify the scope of the then-equivalent of (c)(2). Congress did so by making clear that aliens were "released" from criminal custody and thus could be held without bond at the moment they were released from incarceration, even though they might still be on parole or supervised release. 26 In revising the "upon completion" clause, Congress necessarily treated the then-equivalent of the

framing the question on appeal in terms of whether "authority todetain [an alien while he was on parole] pursuant to [the thenequivalent of § 1226(c)] . . . exist[ed]" (emphasis added)). 26 Congress replaced the "upon completion" clause with "upon release of the alien (regardless of whether or not such release is on parole, supervised release, or probation, and regardless of the possibility of rearrest or further confinement in respect of the same offense)." Immigration Act of 1990, § 504(a), Pub. L. No. 101-649, 104 Stat. 4978, 5049-50; H.R. Rep. No. 101-681(I), § 1503, at 148 (1990).- 38 - "when . . . released" clause and its trailing language as limiting the follow-on bar to bonded release. Otherwise, Congress would have had no need to tinker with that language at all in light of the discretion to place aliens in immigration custody that the Attorney General otherwise had. And, by passing the amendments, Congress necessarily retained (albeit in revised form) that limitation on the operation of both the custody directive and the

bar to bonded release. 27 Finally, in 1996, not long before the IIRIRA's enactment, Congress further amended the mandatory detention statute while again retaining the same structure, which again naturally reads as if those barred from release are those that must be picked up. See AEDPA, § 440(c), Pub. L. No. 104-132, 110

27 We do not find our colleagues' contrary reading of the 1990 House report -- in which Congress was supposedly responding to a concern that the "upon completion" clause might be read to displace, as to aliens on parole, the Attorney General's general and unqualified grant of discretionary authority to take aliens into immigration custody, see infra at 94-95 -- persuasive. Congress was responding to Eden and the immigration judge in that case did clearly conclude that the Attorney General had the authority to place an alien on parole in immigration custody under the then-equivalent of § 1226(a). See Eden, 20 I. & N. Dec. at 210. In offering a contrary reading of the report, our colleagues ignore the introductory sentence of the relevant portion of the report, which we read to supply the context for the sentences that follow: "Current law . . . requires INS to incarcerate alien aggravated felons without bond immediately upon completion of the alien's criminal 'sentence.'" H.R. Rep. No. 101-681(I), § 1503, at 148 (1990) (emphasis added). We therefore read the sentences that follow to be referring to the authority to incarcerate aliens without bond under the mandatory detention provision. See id.- 39 - Stat. 1214, 1277 (retaining "upon release"/"such felon" structure). And prior to the passage of § 1226(c), district courts not surprisingly treated the retained "upon release" clause as if it conditioned the retained "such felon" clause, just as the BIA and Congress itself had treated the analogous clauses in prior detention mandates. 28 We generally "assume that Congress is aware of existing law when it passes legislation," see Miles v. Apex, 498 U.S. 19, 32 (1990), so we should assume that Congress understood the prevailing interpretation of the relationship between the custody

28 District courts held that the AEDPA did not apply retroactively to aliens who had been convicted and released from incarceration before its enactment in part because the "upon release" clause implicitly limited the application of the detention mandate, including the aspect of the mandate governing bonded release, to people taken into custody after the AEDPA's passage. See, e.g., DeMelo v. Cobb, 936 F. Supp. 30, 36 (D. Mass. 1996), vacated as moot after the IIRIRA's passage, 108 F.3d 328 (1st Cir. 1997) (per curiam) (concluding "that the language 'upon release of the alien from incarceration' implies a time of release after the effective date of the Act" and thus makes the detention mandate as a whole prospective in application); Villagomez v. Smith, No. C96-20 1141C, 1996 WL 622451, at *2 (W.D. Wash. July 31, 1996) (unpublished) (stating that the AEDPA's detention mandate as a whole cannot apply to aliens convicted and released before its enactment because of the "straightforward" "upon release" language); Montero v. Cobb, 937 F. Supp. 88, 95 (D. Mass. 1996); In re Reyes, Case No. B-94-80 (S.D. Tex. May 31, 1996); see also Grodzki, 950 F. Supp. at 342 (holding that the "upon release" language "at least implies that custody commence within a reasonable time after release from incarceration" and thus that petitioner was entitled to individualized bond hearing given the lapse in time between when he was released from incarceration and when he was taken into immigration custody).- 40 - directive and the bar to bonded release to be a linked one. Afterall, courts were consistently interpreting that relationship postAEDPA in the same way Congress and the BIA had interpreted that relationship in the similarly worded clauses pre-AEDPA. 29 And while Congress broadened the cross-reference in the present

29 Our colleagues, see infra at 91-92, following Rojas's lead, see Rojas, 23 I. & N. Dec. at 122-24, find instructive the 1991 revision to an exception to the bar to bonded release contained in the 1990 detention mandate. See Immigration Act of 1990, § 504(a), Pub. L. No. 101-649, 104 Stat. 4978, 5049-50; Miscellaneous and Technical Immigration and Naturalization Amendments of 1991, § 306(a)(4), Pub. L. No. 102-232, 105 Stat. 1733, 1751. Rojas contends that the text of the exception to the bar to bonded release (set forth in the revised version of paragraph (B)) shows that the "upon release" constraint in the then-effective detention mandate (set forth in paragraph (A)) limited neither the class of lawfully admitted aliens referenced in (B)'s exception nor "such felon[s]" referenced in (A)'s bar to bonded release. 23 I. & N. Dec. at 124. But as the legislative history just described shows, in crafting that 1990 detention mandate, Congress plainly did intend for the "upon release" requirement to modify the "such felon[s]" who were subject to (A)'s bar to bonded release. We thus see no basis for concluding that Congress suddenly intended to alter the relationship between the "upon release" and "such felon" clauses in paragraph (A) in 1991 by way of a technical amendment to paragraph (B) that does not appear to have been made for any such consequential purpose. See Cong. Research Serv., Summaries for Miscellaneous and Technical Immigration and Naturalization Amendments of 1991 (H.R. 3049, 102nd Cong.), https://www.govtrack.us/congress/bills/102/hr3049/summary (summarizing the 1991 revision as applying the exception in (B) to all "lawfully admitted aliens" as opposed to just aliens "lawfully admitted for permanent residence"). Consistent with a modest understanding of the 1991 technical revision's import, we read (B) -- by virtue of the fact that (A) is "subject to paragraph (B)" -- to refer merely to a subset of "such felon[s]" in (A), which is to say felons taken into immigration custody "upon release." In any event, we question the salience of paragraph (B) for present purposes given that it had been deleted by the AEDPA by the time Congress got around to enacting the IIRIRA, see AEDPA § 440(c), 110 Stat. at 1277.- 41 - detention mandate to account for the fact that not all aliens subject to the present mandate qualify as "felons," we do not think Congress thereby intended to alter fundamentally the relationship between the custody directive and the bar to bonded release. In fact, the evidence is to the contrary. See H.R. Rep. 104-469(I) (1996), 1996 WL 168955, at *230 (stating that § 1226(c) was intended to "restate[]" the provisions of the immediately preceding detention mandate codified in the AEDPA).

**3.** In countering the substantial evidence from the legislative history that points against Rojas, the government and our colleagues give great weight to an April 1995 report from the Senate Committee on Governmental Affairs. See S. Rep. No. 104-48 (1995), 1995 WL 170285. The Supreme Court relied on that report in Demore v. Kim, 538 U.S. 510, 518-22 (2003), to explain why Congress could have had a reason for mandating the detention without bond of criminal aliens in order to respond to the contention that such mandatory detention was inherently arbitrary. In addressing that constitutional challenge to Congress's power to enact a detention mandate of any scope, the Supreme Court did not purport to enlist that report to describe the class of aliens subject to the mandate § 1226(c) actually imposed. And for good reason.- 42 - That 1995 report was not linked to any particular bill. And that report predates not only § 1226(c) but also the immediate precursor to (c), which used the same "upon"/"such felon" language that tracked the 1988 mandate and its revisions that we have just described. The 1995 Senate report cannot offer any support, therefore, for the suggestion that the present detention mandate must have de-linked the custody directive and bar to bonded release that had been linked in those prior versions. And, in fact, the report does not speak to that issue at all. To be sure, that report does show that its authors were "concerned with detaining and removing all criminal aliens," Rojas, 23 I. & N. Dec. at 122 (emphasis in original); see also Sylvain v. Attorney Gen. of U.S., 714 F.3d 150, 160 (3d Cir. 2013). But in stating that general concern, the report does not demonstrate that Congress intended to paint with the broad brush the government suggests that it used in enacting § 1226(c)(2). See Saysana, 590 F.3d at 16-18 ("The mandatory detention provision does not reflect a general policy in favor of detention . . . ."). The report does also suggest a variety of ways to address the concern that "criminal aliens" (i.e., aliens with deportable offenses) do not show up to removal proceedings. These suggestions range from increasing detention bed space to accommodate enhanced detention efforts generally, to expediting the removal process so that final adjudication occurs while an alien is still in criminal- 43 - custody, to expanding the role of mandatory detention (§ 1226(c)) in relation to discretionary detention (§ 1226(a)) by subjecting all criminal aliens to (c). See S. Rep. No. 104-48 (1995), 1995 WL 170285, at *3-4, *21, *23, *31-32. The report nowhere indicates, however, that Congress wanted to expand the role of mandatory detention haphazardly by de-linking (c)(1) and (c)(2), such that the bar to bonded release would apply to persons who were not even subject to the custody directive at all because they had never been in the criminal custody from which they were then "released" as (c)(1) contemplates. See generally id. 30

30 Our colleagues find support for Rojas in Congress's evident intent to make it more difficult for certain criminal aliens to obtain relief from a final order of removal, see infra at 82-84, on the apparent assumption that the risk of flight is greater for aliens who are more certain to be removed (and this class is an especially dangerous one). But the petitioners have not yet faced a definitive adverse judgment in their removal proceedings and so may not in fact be removed. Moreover, aliens taken into custody under § 1226(c) may also have a basis for discretionary relief in the form of cancellation of removal, see Lora, 2015 WL 6499951, at *3, *12, or some other form of relief, such as a U Visa (a type of visa set aside for victims of certain crimes). We thus see no justification for the inference that Congress, in making it harder to get relief from a final removal order, must have intended to deny bond to those who might not be ordered removed at all. In fact, as Congress surely knows, an alien's inability to get bonded release can limit the alien's capacity to obtain legal representation or otherwise obtain relief from removal, see Robert A. Katzmann, The Legal Profession and the Unmet Needs of the Immigrant Poor, 21 Geo. J. Legal Ethics 3, 10 (2008); Moncrieffe v. Holder, 133 S. Ct. 1678, 1690 (2013), making the impact of mandatory detention prior to a final removal order especially harsh in cases where avenues for relief following such order have been curtailed.- 44 - **4.** In sum, Rojas offers only one reason for concluding that these petitioners may not be given a bond hearing and that reason has nothing to with what the word "when" means. On Rojas's view, § 1226(c)(2) applies to any alien who has committed an (A)-(D) offense, regardless of whether the alien was ever in and "released" from criminal custody as (c)(1) requires, let alone "when" the alien was released from it. And that is because Rojas holds that the "when . . . released" clause as a whole is irrelevant to (c)(2). But when we consider the text of (c)(2) in light of the structure of the IIRIRA as a whole and the legislative history, we do not believe that Rojas offers a tenable construction of the detention mandate. After applying the traditional tools of statutory interpretation, we conclude that Congress did clearly speak to the precise issue Rojas addressed regarding the relevance of the "when . . . released" clause to the bar to bonded release in § 1226(c)(2). And Congress clearly addressed it in the oppositeway from Rojas. That is, Congress clearly intended for the crossreference in (c)(2) to refer to aliens who have committed (A)-(D) offenses and who have been taken into immigration custody "when . . . released" from criminal custody, in accordance with the Attorney General's duty under (c)(1).- 45 - In concluding that Rojas does warrant deference, our colleagues repeatedly emphasize that it is reasonable to conclude that the timeliness of an alien's immigration custody is not determinative of whether the detention mandate applies. But it is important not to confuse the outcome that results from Rojas's interpretation of the mandate's scope with the interpretation itself. For while it is true that Rojas's conclusion that the "when . . . released" clause as a whole is irrelevant to § 1226(c)(2) necessarily makes timeliness irrelevant to the operation of (c)(2), Chevron is clear that it is the agency's interpretation of the statute and not the outcome that follows from that interpretation that deserves our deference. See Lin v. U.S. Dep't of Justice, 416 F.3d 184, 191-92 (2d Cir. 2005) (declining to defer to BIA's summary affirmance of an immigration judge decision because summary affirmance indicates approval of only "the result reached in the decision" rather than "all of the reasoning of that decision" and thus does not contain "the sort of authoritative and considered statutory construction that Chevron deference was designed to honor"). And that must be the case, as the reason we defer to agency interpretations is precisely because we are supposed to give weight to their reasoned judgment. For Chevron purposes, therefore, the contention that the legislative history or the structure of the IIRIRA does not compel- 46 - the timing-based outcome that the petitioners favor amounts to a non sequitur. What matters is that Rojas implausibly ascribes an intention to Congress to place greater limits on the Attorney General's discretion to take aliens into custody in the first place than on the Attorney General's discretion to release them once they are in custody. And so, having determined under Chevron step one that Rojas's interpretation of the relationship between (c)(1) and (c)(2) conflicts with Congress's evident intent and thus does not merit deference, we now turn to the question that remains: the meaning of (c)(1)'s "when . . . released" clause.

**III.** In taking up this issue, we confront the question that Rojas never reaches: does "when" impose a time limit for taking an alien into custody pursuant to (c)(1) that renders (c)(2)'s bar to bonded release inapplicable to these petitioners due to the remoteness of their release from criminal custody? See Sylvain, 714 F.3d at 157 n.9 (stating that Rojas "did not explicitly interpret" the word "when"). The government argues that the word "when" imposes no such time limit, either because "when" means "if" or "any time after" or because Congress at most used the word "when" to trigger a duty to act promptly that persists indefinitely. The BIA, however, has never adopted either view, and such litigating- 47 - positions are not entitled to Chevron deference. 31 See United States v. Mead Corp., 533 U.S. 218, 231 (2001). We thus must decide the clause's meaning on our own. See Santana v. Holder, 731 F.3d 50, 53 (1st Cir. 2013). To do so, we first consider whether the word "when" as used here is merely a synonym for "if" or "any time after" and consequently conveys no sense of immediacy at all. We then consider whether, even if Congress intended for the word "when" to convey immediacy, the word merely reflects a legislative preference for timely action and thus does not impose a true time limit.

31 Although the government suggests that Rojas construed "when" to mean, in effect, "any time after," Rojas did not, as it held that the word was irrelevant to § 1226(c)(2)'s operation. The government reads too much into Rojas's assertion that the "when . . . released" clause "specifies[s] the point in time at which [the Attorney General's] duty [under (c)(1)] arises." See Rojas, 23 I. & N. Dec. at 121. In so stating, Rojas merely clarified that "when . . . released" modifies "take into custody" rather than the "alien" in (c)(1), not that "when" imposes no deadline. In fact, the BIA has seemed to set forth a time-limited meaning of "when" several times. See id. at 122; see also Matterof Saysana, 24 I. & N. Dec. 602, 607 (BIA 2008); Matter of ValdezValdez, 21 I. & N. Dec. 703, 708 (BIA 1997). The government's interpretation of the meaning of the word "when" is thus not entitled to Chevron deference. Given that the BIA's position on the meaning of "when" is at worst inconsistent and at best consonant with petitioners' time-limited reading, we also would not defer under Skidmore to such an interpretation, assuming Skidmore deference even applies to the government's litigating position in this case. See Skidmore v. Swift & Co., 323 U.S. 134, 140 (1944) (stating that the opinion of an agency is entitled to respect only to the extent it has the "power to persuade").- 48 - **A.** We begin our analysis of the first issue with the observation that Congress chose a word, "when," that naturally conveys some degree of immediacy, Castañeda, 769 F.3d at 42-44, as opposed to a purely conditional word, such as "if." See Webster's Third New International Dictionary 2602 (2002) (defining "when" as "just after the moment that"). Consistent with the conclusion that this choice indicates that Congress intended for "when" to convey immediacy, § 1226(c)(1) says "when the alien is released," not "when the alien has been released" or "after the alien is released." Similarly, the structural placement of the "when . . . released" clause suggests Congress did not use "when" simply to announce a condition, as the clause does not directly follow "any alien who." Cf. Rojas, 23 I. & N. Dec. at 128-29. 32 If Congress really meant for the duty in (c)(1) to take effect "in the event of" or "any time after" an alien's release from criminal custody, we would expect Congress to have said so, given that it spoke with just such directness elsewhere in the IIRIRA. See, e.g., 8 U.S.C. § 1231(a)(5) ("[T]he alien shall be

32 The Rojas concurrence suggested that the "when . . . released" clause in (c)(1) does not impose a timing constraint because it modifies only the offenses denominated in subparagraphs (A)-(D) of (c)(1), rather than the duty to "take into custody." See Rojas, 23 I. & N. Dec. at 128-29 (Moscato, concurring and dissenting). Neither the BIA, the government, nor our colleagues advance this view, however, and we see no basis for this view given the structural placement of the clause.- 49 - removed under the prior order at any time after the reentry." (emphasis added)); cf. United States v. Willings, 8 U.S. (4 Cranch) 48, 54 (1807) (concluding that Congress intended the word "when" in a federal maritime statute to mean "if" or "in case" because the statute contained clear indicia of conditional intent (for example, the phrase "in every such case" recurred)). In fact, the BIA itself noted in Rojas that "[§ 1226(c)] does direct the Attorney General to take custody of aliens immediately upon their release from criminal confinement." Rojas, 23 I. & N. Dec. at 122 (emphasis added). As to just how promptly Congress intended for the government to act, there is more uncertainty, as the panel recognized when it construed the word "when" to mean "within a reasonable time after." See Castañeda, 769 F.3d at 44. But given the unexplained, years-long gap between when these petitioners were released from criminal custody and when they were taken into immigration custody, we need not define the bounds of reasonableness in this case as they were plainly exceeded. 33 Thus,

33 The government and our colle agues contend that it is implausible that Congress would have exempted aliens from § 1226(c) merely in consequence of the remoteness of their release from criminal custody given that such a gap in custody might be attributable to other forces. See Gov. Br. at 8-9; see infra at 83. For example, the government and our colleagues point to evidence that some state and local authorities may frustrate the ability of the Attorney General to place aliens in custody in a timely fashion under (c)(1). Id. But the agency charged with- 50 - for present purposes, it is enough to conclude that Congress used the word "when" to convey some degree of immediacy and not simply to set forth a condition. 34

administering the Act has not purported to define the word "when" or its temporal bounds, let alone how such period of time should be tolled in the circumstances the government and our colleagues identify or in other circumstances that might arise, such as when an alien receives a non-carceral sentence. See Lora, 2015 WL 6499951, at *6; Kotliar, 24 I. & N. Dec. at 125; West, 22 I. & N. Dec. at 1410. We do not believe that such fact-specific questions about tolling provide a basis for concluding that "when" is best read in context to mean "if" or "any time after," given the other evidence of legislative intent. 34 Our colleagues contend that the petitioners' view of "when" would be at odds with the canon against surplusage in light of the "released after" clause of the IIRIRA § 303(b)(2). But we do not see how. At worst, the "released after" clause is a clarifying provision in an ancillary and potentially never operative measure. Cf. In re Fahey, 779 F.3d 1, 7 (1st Cir. 2015) (indicating that language that is not strictly speaking necessary, if nonetheless clarifying, need not be thought to run afoul of the canon against surplusage). That is because the "released after" clause appears to have been intended to clarify which rules would apply to existing detainees when the TPCR expired. Aliens who were immediately taken into immigration custody upon their release from criminal custody during the transition period were subject to the restrictions on bonded release imposed by the TPCR. While the IIRIRA § 303(b)(2) did state the effective date of the new permanent rules § 1226(c) set forth, the "effective date" clausedid not make clear whether the permanent rules or the by-thenexpired TPCR rules would govern those persons in mandatory detention when the TPCR expired. Thus, the "released after" clause in the IIRIRA § 303(b)(2) would seem to have been intended to perform the useful function of making clear -- as part of a savings clause, see Garvin-Noble, 21 I. & N. Dec. at 681; Adeniji, 22 I. & N. Dec. at 1110-11 (emphasizing "uncertainty . . . in discerning how Congress expected the [released after] provision to operate," given that Congress may have "intended" but inadvertently "neglected" to incorporate this provision into a broader savings clause in the TPCR) -- that § 1226(c) would apply only to aliens released from criminal custody "afte r" the transition period. Conversely, the old TPCR rules for mandatory detention would- 51 - **B.** The part of the conference report to the IIRIRA that describes § 1226(c) supports the conclusion that Congress did not intend for the word "when" to have a purely conditional meaning. And so, too, does the legislative history to (c) that indicates it was meant to mirror the precursor mandates, each of which used a timing word that was understood to convey immediacy. The conference report states that "[t]his detention mandate applies whenever such an alien is released from imprisonment, regardless of the circumstances of the release." H.R. Conf. Rep. No. 104-828 (1996), 1996 WL 563320, at *210-11 (emphasis added). As used in that report, "whenever" is most plausibly read to mean at the time that the alien is released from imprisonment, whenever that event may occur, rather than simply "if" that event occurs. Indeed, had Congress intended by the use of "whenever" to mean "if" or "any time after," we again would expect the report to have said "after such alien is released" or "whenever such an alien has been released."

continue to govern aliens held in mandatory detention pursuant to those transition rules. Thus, the "released after" clause is by no means unnecessary if "when" conveys immediacy. A misplaced concern about surplusage thus should not dictate a meaning of the word "when" that is so at odds with the text, structure, and legislative history. See King v. Burwell, 135 S. Ct. 2480, 2492- 93 (2015).- 52 - Consistent with this conclusion, the legislative history to the subsection that would become § 1226(c) indicates that Congress intended to "restate[]" the provisions of the direct precursor to (c) "regarding the detention of an alien." See H.R. Rep. No. 104-469(I) (1996), 1996 WL 168955, at *230. And that direct precursor, which is codified in the AEDPA, used the word "upon," which was used in and understood to have conveyed immediacy in all the detention mandates preceding § 1226(c). 35 For example, the House Report on the 1990 amendments to the 1988 mandatory detention statute characterized "current law" as "requir[ing] [the] INS to incarcerate alien aggravated felons without bond immediately upon completion of the alien's criminal 'sentence.'" H.R. Rep. No. 101-681(I), § 1503, at 148 (1990), reprinted in 1990 U.S.C.C.A.N. 6472, 6554, 1990 WL 188857 (emphasis added); cf. Sheffield, 435 U.S. at 129-35. And the district courts that construed the word "upon" in the AEDPA's detention mandate reached the same conclusion as Congress had about the 1988 measure -- its use of the word "upon" conveyed immediacy. See, e.g., DeMelo, 936 F. Supp. 30, 36 (D. Mass. 1996), vacated as moot after the IIRIRA's passage, 108 F.3d 328 (1st Cir. 1997).

35 In fact, as we have noted, just prior to conference on the IIRIRA, a leading Senate sponsor of the IIRIRA described § 1226(c) as "ensur[ing] that aliens who commit serious crimes are detained upon their release from prison until they can be deported . . . ." 142 Cong. Rec. S10572-01 (daily ed. Sept. 16, 1996), 1996 WL 522794 (statement of Sen. Simpson) (emphasis added).- 53 - In sum, the legislative history as a whole indicates that Congress used the word "when" just as it had used the word "upon": to convey a sense of immediacy. We thus conclude that the legislative history reinforces the textual indication that Congress did not intend for the word "when" to be merely a synonym for "if" or "any time after."

**C.** That brings us to the question of whether Congress intended for the word "when" merely to express a legislative preference for timely action or whether it was instead intended to impose a deadline for the application of the bar to bonded release set forth in § 1226(c). To answer this question, we consult the principles underlying the so-called loss-of-authority canon. 36

36 Our colleagues, in concluding that "when" merely expresses a preference for timely action, do not rely on loss-of-authority principles. See infra at 98-99. They instead reason that even if Rojas is wrong, whether an alien was timely taken into immigration custody is just an exogenous fact and thus does not have any bearing on the class of aliens to whom § 1226(c) applies. See id. If we follow, the suggestion appears to be that the word "released" and the trailing portions of the "when . . . released" clause do refer to something endogenous to the alien and thus do characterize the alien to whom (c) applies, even though the word "when" does not. But aliens do not release themselves any more than they choose when they are released. We thus do not see how the line between exogenous and endogenous facts could be drawn so finely as to attribute to Congress an intent to carve up the "when . . . released" clause in this odd way, even if there were any textual basis for construing the Attorney General's duty under (c) as being limited by facts endogenous to the alien rather than by all relevant ones. And, as noted, there is no textual basis for concluding that the word "when" -- and whatever limitations- 54 - That interpretive aid comes into play where Congress has mandated that the government "shall" do something within a certain time frame and there is a question about the consequence Congress intends for the government's failure to complete the required action within that time frame. See Barnhart v. Peabody Coal Co., 537 U.S. 149, 158-59 (2003). The canon generally counsels that: "[i]f a statute does not specify a consequence for noncompliance with statutory timing provisions, the federal courts will not in the ordinary course impose their own coercive sanction." Id. at 159. The animating principle behind this canon is one of plausibility given the context: "if Congress had meant to set a counterintuitive limit on authority to act, it would have said more than it did." Id. at 163 (emphasis added). The government contends that § 1226(c) "contains no sanction for late executive action," Gov. Br. at 10, and that it would be counterintuitive to render (c) inapplicable when the

that word imposes -- does not constrain the application of (c)(1), as the word clearly and unconditionally modifies the Attorney General's directive to "take into custody." The only possible textual hook for distinguishing between endogenous and exogenous facts, therefore, resides in (c)(2)'s "described in" language. But making a distinction on this basis for the purpose of understanding the bounds of the Attorney General's duty under (c) would still create an arbitrary line-drawing problem. And such a distinction would also incongruously de-link the custody directive in (c)(1) from the bar to bonded release in (c)(2) by subjecting the custody directive to a timing constraint not applicable to the bar to release.- 55 - executive is late in taking an alien into custody given the detention-maximizing purpose underlying (c). But we do not agree. This case is not like those in which enforcement of a time limit would require a court to fashion a coercive sanction that appears nowhere in the text and that would completely strip the government of authority "to get [the] . . . job done," id. at 160. See, e.g., id. at 156 (proposed sanction was complete loss of ability to direct award of retirement benefits to late-assigned beneficiaries); Brock v. Pierce Cty., 476 U.S. 253, 258 (1986) (proposed sanction was complete loss of ability to recover misused federal funds); Dolan v. United States, 560 U.S. 605, 609 (2010) (proposed sanction was complete loss of ability to order persons convicted of certain crimes to pay restitution to victims). Rather, the putative time limit at issue here appears in an express exception, § 1226(c), to an otherwise broad grant of discretionary authority, § 1226(a), regarding the custody and release of aliens awaiting the outcome of removal proceedings, just as all theprecursors to § 1226(c) were framed as exceptions to thenequivalents of § 1226(a). Thus, enforcement of the time limit here, unlike in the other cases in which loss-of-authority principles were applied, would merely render inapplicable an express limit on a grant of authority and thus necessarily result in a reversion to that authority.- 56 - Given this distinct context, the key question is whether Congress intended for the requirement that the Attorney General timely take aliens into immigration custody to circumscribe the scope of this exception. As a textual matter, there is no indication that Congress intended for subparagraphs (A)-(D) in § 1226(c)(1) but not the "when . . . released" clause to define the outer limit of the Attorney General's discretion that the exception in (c) establishes. The text of (c) also does not itself indicate that the timeliness of an alien's custody is merely a procedural requirement that need not be complied with in a strict

sense. There remains the question whether it nevertheless would be counterintuitive to read "when" to circumscribe the exception's scope. The express presentation of § 1226(c) as an exception to (a) that applies only if all of its conditions are met accords with the quite sensible intuition that Congress did mean to distinguish between aliens who fall within the scope of (a) and aliens who fall within the scope of (c) on the basis of the timeliness of their immigration custody. 37 In construing the

37 That Congress intended to craft a relatively narrow detention mandate is hardly implausible. After all, Congress did not adopt the recommendation in the 1995 Senate report to expand the class of aliens subject to mandatory detention to "all criminal aliens." See S. Rep. No. 104-48 (1995), 1995 WL 170285. Rather, setting aside any limitations imposed by the "when . . . released" clause, Congress limited mandatory detention under § 1226(c) to- 57 - intended scope of another aspect of § 1226(c), we explained in Saysana that "[i]t is counter-intuitive to say the least to say that aliens with potentially longstanding community ties are, as a class, poor bail risks." See Saysana, 590 F.3d at 17. And we added that "by any logic, it stands to reason that the more remote in time a conviction becomes and the more time after a conviction an individual spends in a community the lower his bail risk is likely to be." See id. at 17-18. 38 Thus, in this context, we conclude that the timing word "when" is best read to impose an outer limit on the exception to the categorical bar to discretionary release carved out by § 1226(c). In consequence, aliens like petitioners, who due to the unexplained years-long gap between their criminal custody and

aliens who have committed certain enumerated offenses and who were "released after" the TPCR expired (by virtue of the IIRIRA § 303(b)(2)); see also Saysana, 590 F.3d at 15-16 (holding that § 1226(c)(1) is not triggered until an alien is released from custody for having committed an offense specified in subparagraphs (A)-(D), as opposed to being triggered by release from any type of criminal custody). 38 The Second Circuit held that, to avoid "serious constitutional concerns," § 1226(c) "must be read as including an implicit temporal limitation," such that aliens taken into immigration custody pursuant to § 1226(c) cannot be held without a bond hearing for more than six months. Lora, 2015 WL 6499951, at *10-11. In so holding, the Second Circuit noted that indefinite detention "has real-life consequences for immigrants and their families," and that it is particularly concerning when "[n]o principled argument has been mounted for the notion that [the detainee] is either a risk of flight or is dangerous." Id. at *12.- 58 - their immigration custody have had the opportunity to re-establish community ties, are not subject to the bar to release set forth in (c). They are subject instead to the default rule of discretionary release set forth in (a). 39 To be sure, Congress was concerned about criminal aliens failing to show up for removal proceedings. See Rojas, 23 I. & N. Dec. at 122. But Congress expressly directed the executive to address that concern by complying with the mandate to pick up aliens within a reasonable time frame. In fact, Congress established transition rules that the Attorney General could invoke to ensure the government would be prepared to comply promptly with § 1226(c) by the time those rules expired. See Adeniji, 22 I. & N. Dec. at 1110. As a result, we do not believe Congress intended that the executive could fail to pick up an alien within a reasonable time and then, despite that unexplained delay, deny that alien the chance to seek bonded release notwithstanding that alien's years of living freely. See Castañeda, 952 F. Supp. 2d at 318 n.10

39 Our colleagues' gardening example is of little help in establishing the context for discerning Congress's intent in enacting a detention mandate that "touches upon matters of both personal liberty and the control of our nation's borders." See infra at 76. As for our colleagues' suggestion that Congress had "no good reason" to distinguish between aliens timely taken into custody and aliens not timely taken into custody, our prior decision in Saysana supplies a compelling reason, see Saysana, 590 F.3d at 17, as does Congress's treatment of § 1226(a) as a backstop source of detention authority.- 59 - ("[T]he experience of having one's liberty stripped away is drastically different from the experience of not having it restored."); cf. DeWitt v. Ventetoulo, 6 F.3d 32, 34-36 (1st Cir. 1993) (holding that revoking a mistakenly granted suspension of sentence and re-imprisoning a defendant after years of being free violated due process). And there certainly is nothing in the legislative history to indicate that Congress did have that specific intention. 40 For these reasons, the principal precedent that the government, like the Third Circuit in Sylvain, 714 F.3d at 158- 61, relies on, United States v. Montalvo–Murillo, 495 U.S. 711 (1990), is not to the contrary. That case concerned whether the government's failure to hold a bond hearing in a timely fashion barred the government from assuming pre-trial custody of a criminal defendant under the Bail Reform Act (BRA). See Montalvo-Murillo,

40 In fact, the legislative history accords with the notion that Congress wanted to limit § 1226(c) to aliens coming right out of criminal custody in order to help immigration authorities conserve scarce detention bed space so that aliens who needed to be detained under § 1226(a) could be. See Criminal and Illegal Aliens: Hearings Before the Subcomm. on Immigration and Claims of the House Comm. on the Judiciary, 104th Cong. (Sept. 5, 1996) (statement of David Martin, General Counsel of INS) (noting that criminal aliens subject to the AEDPA's detention mandate imposed severe burdens on detention bed space and crowded out space for aliens who did not come within such mandate and only discussing efforts by immigration authorities to take aliens into custody just as they were leaving incarceration); Amicus Br. of Frm. Imm. Judges and DHS Sec. Officials at 17-20 (describing scarce detention bed space).- 60 - 495 U.S. at 717. Notably, but not surprisingly, the BRA specified no consequence for holding a hearing late. And the Court thus held that such failure should not be deemed to have the drastic and disproportionate consequence of depriving the government of its power to place a criminal defendant in custody at all by mandating the release of the criminal defendant. See id. at 719-

20. 41 Here, however, the putative time limit appears within an express exception to a grant of authority. So § 1226 itself makes clear what consequence would follow if such time limit is not met. Moreover, that consequence would not strip the executive of the power to assume custody of a potentially dangerous or flight-prone criminal defendant. Instead, the Attorney General would merely retain her otherwise broad discretion to decide whether to assume and maintain custody of an alien pursuant to whatever rules she

41 The Supreme Court's decision in Barnhart, 537 U.S. at 152, is similar. The appellants argued that a certain provision of the Coal Act specified the consequence for the government's failure to timely comply with another provision, id. at 153, 163, but the Court rejected this argument because the Coal Act's text did not expressly link the two provisions and there was evidence to suggest that Congress did not think of the two provisions as related. Id. at 163-65. Moreover, the Court reasoned that it was implausible to think that Congress would have wanted that separate provision to control as a policy matter, so the consequence was untenable. Id. at 164. Here, of course, Congress expressly styled § 1226(c) as an exception that restricts the power otherwise granted under (a), so the asserted consequence is clearly linked to the asserted act of noncompliance. And, for the reasons discussed, we hardly think it is counterintuitive for Congress to have intended that (a) would control if (c)'s conditions are not met.- 61 - may lawfully establish for exercising such discretion under (a). Because this consequence follows from the text and because the text accords with the reasonable and intuitive understanding that Congress intended to distinguish between aliens like petitioners and aliens who were taken into custody "when . . . released," see Saysana, 590 F.3d at 17, we read the timing condition at issue here as circumscribing the Attorney General's duty under (c). Thus, at least absent an authoritative agency construction of § 1226(c)(2), we conclude that the word "when" does set forth a time constraint on (c) that expires after a reasonable time. And for that reason, we reject the government's contention that "when" must be read merely to trigger an indefinitely persisting duty, such that it imposes no outer bound on the scope of the exception § 1226(c) sets forth.

**IV.** The current version of the detention mandate requires that aliens who have committed certain offenses be taken into immigration custody in a timely manner following their release from criminal custody. The detention mandate further provides that only such aliens must then be held without bond until the completion of the removal process. These petitioners were released from criminal custody years before they were first placed in immigration custody. For that reason, they clearly do not fall within "this detention mandate." H.R. Conf. Rep. No. 104-828- 62 - (1996), 1996 WL 563320, at *210-11. Accordingly, we agree with the two district courts that these petitioners have the right to individualized bond hearings at which they can make the case that they do not pose sufficient bond risks, just as the Attorney General specified in the regulations that she issued pursuant to § 1226(a).- 63 - **TORRUELLA** , **Circuit Judge (Concurring).** I recognize that the Supreme Court has determined that Congress may, "[i]n the exercise of its broad power over naturalization and immigration, . . . regularly make[] rules that would be unacceptable if applied to citizens," Mathews v. Diaz, 426 U.S. 67, 79-80 (1976); see also Demore v. Kim, 538 U.S. 510, 521 (2003), and that the right to bail is not absolute. United States v. Salerno, 481 U.S. 739, 754-55 (1987). Yet, I must register my discomfort with respect to 8 U.S.C. § 1226(c). I am compelled to suggest that the indefinite detention without access to bond or bail of any person in the United States violates due process. See Wong Wing v. United States, 163 U.S. 228, 238 (1896) ("[A]ll persons within the territory of the United States are entitled to the protection guarantied [sic] by th[e Fifth and Sixth] amendments [sic] . . . ."); Yick Wo v. Hopkins, 118 U.S. 356, 369-70 (1886) (applying Fourteenth Amendment due process and equal protection provisions "to all persons within the territorial jurisdiction, without regard to any differences of race, of color, or of nationality"). The U.S. Constitution specifically addresses the right to bail. It is the first concern of an amendment that names just three subject matters. "Excessive bail shall not be required, nor excessive fines imposed, nor cruel and unusual punishments inflicted." U.S. Const. amend. VIII. As the Supreme Court has elsewhere noted, "[b]ail is basic to our- 64 - system of law." Herzog v. United States, 75 S. Ct. 349, 351 (Douglas, Circuit Justice, 9th Cir. 1955) (citing U.S. Const. amend. VIII; Stack v. Boyle, 342 U.S. 1 (1951)). The Fifth Amendment mandates that no "person . . . be deprived of life, liberty, or property, without due process of law." U.S. Const.

amend. V. When the government exercises its discretion to subject a person to detention without access to a bond hearing after the condition justifying detention has been in existence for aconsiderable period of time, it disregards what is by then selfevident -- that said subject is neither a flight risk nor a danger to society, the primary reasons for denying bail. See 18 U.S.C. § 3142(e)(1); cf. Carlson v. Landon, 342 U.S. 524, 542 (1952) ("There is no denial of the due process of the Fifth Amendment under circumstances where there is reasonable apprehension of hurt from aliens charged with a philosophy of violence against this Government."). Although Judge Kayatta, Chief Judge Howard, and Judge Lynch view this issue differently, infra at 104-05, this Court has elsewhere described their views as counter-intuitive. Saysana v. Gillen, 590 F.3d 7, 17-18 (1st Cir. 2009) ("[I]t is counter-intuitive to say that aliens with potentially longstanding community ties are, as a class, poor bail risks. . . . By any logic, it stands to reason that the more remote in time a conviction becomes and the more time after a conviction an- 65 - individual spends in a community, the lower his bail risk is likely to be."). Affirming the government's prerogative to incarcerate persons in defendants' situation without bail or bond hearing is not only to allow arbitrary and abusive government action but to condone acts that run contrary to the Constitution. See Herzog, 75 S. Ct. at 351; see also Wong Wing, 163 U.S. at 237. I write separately to ensure that the constitutional concerns raised by § 1226(c) and the government conduct it commands -- the ongoing, institutionalized infringement of the right to bail and right to due process -- are formally acknowledged. Notwithstanding these concerns, we reach the conclusion we must in light of Congress's laws, legislative history, and the Supreme Court's holdings. I thus concur in the judgment.- 66 - **KAYATTA** , **Circuit Judge, with whom HOWARD, Chief Judge, and LYNCH, Circuit Judge, join**  . Congress enacted what is now 8 U.S.C. § 1226(c) because of its concern that immigration judges had proven to be insufficiently accurate predictors of which aliens would "engage in crime and fail to appear for their removal hearings." Demore v. Kim, 538 U.S. 510, 513 (2003); see S. Rep. No. 104-48, at 2 (1995) ("Despite previous efforts in Congress to require detention of criminal aliens while deportation hearings are pending, many who should be detained are released on bond."). To address this concern, Congress identified four categories of what Congress called "criminal aliens." 8 U.S.C. § 1226(c). Section 1226(c), as signed by the President on September 30, 1996, as part of the Illegal Immigration Reform and Immigrant Responsibility Act of 1996 ("IIRIRA"), mandates, first, that the Attorney General "take into custody" these criminal aliens "when the alien is released" from criminal detention (the "custody mandate"). See id. § 1226(c)(1). Section 1226(c) then mandates, second, an end to the practice of immigration judges trying to predict which of those criminal aliens will appear for removal proceedings if ordered to do so. See id. § 1226(c)(2). Under this latter mandate (the "no-release mandate"), the Attorney General must not release the criminal alien from the Attorney General's custody pending resolution of the alien's removal proceeding, unless release is necessary for protection of certain- 67 - persons in connection with an investigation into a major crime. See id. The alien is, however, entitled to an immediate hearing to adjudicate any contention that the alien is not a criminal alien subject to section 1226(c)'s mandates. See 8 C.F.R. § 1003.19(h)(2)(ii). With its evenly divided vote, our court leaves in place two district court decisions holding that, to the extent the Attorney General fails to comply promptly with the custody mandate, immigration judges will find themselves back in the position of predicting which criminal aliens will present themselves for removal if they are released on bail pending the conclusion of their removal proceedings. Indeed, as we understand the reasoning of our colleagues who would affirm the decisions below, any failure by the Attorney General to achieve prompt compliance with the custody mandate renders both the custody and the no-release mandates inapplicable. For the reasons we explain in this opinion, we would instead join all four other circuits that have considered this issue by sustaining the Board's current practice in complying with section 1226(c). See Lora v. Shanahan, No. 14-2343-PR, 2015 WL 6499951, at *8–9 (2d Cir. Oct. 28, 2015); Olmos v. Holder, 780 F.3d 1313, 1327 (10th Cir. 2015); Sylvain v. Attorney General, 714 F.3d 150, 161 (3d Cir. 2013); Hosh v. Lucero, 680 F.3d 375, 384 (4th Cir. 2012).- 68 - **I. Discussion** We begin by explaining our view that the statute's mandates apply to petitioners, using the same tools of statutory construction that our colleagues employ to decide this case at step one of the Chevron analysis. See Chevron, U.S.A., Inc. v. Nat. Res. Def. Council, Inc., 467 U.S. 837, 842–43 (1984). We also explain why our colleagues' parsing of section 1226(c), even if correct, fails to support the conclusion that the Attorney General's failure to take a criminal alien into custody immediately upon release somehow eliminates any further requirement to comply with Congress's mandates set forth in section 1226(c). Finally, although our colleagues do not reach Chevron step two, see id. at 843, and therefore do not consider the constitutional avoidance argument that was relied upon in the vacated panel opinion, we do reach step two, and therefore briefly explain why that avoidance argument is not a valid basis for setting aside the Board of Immigration Appeals' ("BIA") reasonable interpretation of section 1226(c).- 69 - **A. The Language and Structure of the Statute** 8 U.S.C. § 1226(a) grants the Attorney General the discretion whether to take into custody aliens charged with removal and whether to continue that custody pending the completion of removal proceedings: (a) Arrest, detention, and release On a warrant issued by the Attorney General, an alien may be arrested and detained pending a decision on whether the alien is to be removed from the United States. Except as provided in subsection (c) of this section and pending such decision, the Attorney General-- (1) may continue to detain the arrested alien; and (2) may release the alien on-- (A) bond of at least $1,500 . . . ; or (B) conditional parole . . . . For certain aliens classified by Congress as "criminal aliens," however, 8 U.S.C. § 1226(c) requires the Attorney General both to take the alien into custody and to maintain that custody without release subject to a narrow exception. Section 1226(c) states in full: (c) Detention of criminal aliens (1) Custody The Attorney General shall take into custody any alien who-- (A) is inadmissible by reason of having committed any offense covered in section 1182(a)(2) of this title, (B) is deportable by reason of having committed any offense covered in section 1227(a)(2)(A)(ii), (A)(iii), (B), (C), or (D) of this title,- 70 - (C) is deportable under section 1227(a)(2)(A)(i) of this title on the basis of an offense for which the alien has been sentence [sic] to a term of imprisonment of at least 1 year, or (D) is inadmissible under section 1182(a)(3)(B) of this title or deportable under section 1227(a)(4)(B) of this title, when the alien is released, without regard to whether the alien is released on parole, supervised release, or probation, and without regard to whether the alien may be arrested or imprisoned again for the same offense. (2) Release The Attorney General may release an alien described in paragraph (1) only if the Attorney General decides pursuant to section 3521 of title 18 that release of the alien from custody is necessary to provide protection to a witness, a potential witness, a person cooperating with an investigation into major criminal activity, or an immediate family member or close associate of a witness, potential witness, or person cooperating with such an investigation, and the alien satisfies the Attorney General that the alien will not pose a danger to the safety of other persons or of property and is likely to appear for any scheduled proceeding. A decision relating to such release shall take place in accordance with a procedure that considers the severity of the offense committed by the alien. Each of the petitioners in this case, after arriving in this country, was convicted of one of the criminal acts listed in section 1226(c)(1)(A)-(D). See Castañeda v. Souza, 769 F.3d 32, 36 (1st Cir. 2014), reh'g granted en banc. There is no dispute- 71 - among the parties that section 1226(c) therefore plainly required the Attorney General: (1) to take petitioners into custody when they were released from incarceration, and (2) to detain them until the conclusion of their respective removal proceedings. The question under consideration is what happens when, as here, the Attorney General does not manage to detain the criminal alien until after the alien's release from incarceration. All members of our en banc panel appear to agree that the mandate of paragraph (2) of section 1226(c) strictly limiting the release of certain persons once detained applies to anyone who is "an alien described in paragraph (1)." So this case pivots, at least in the first instance, on determining the meaning of that phrase. The BIA, in a quite straightforward fashion, construed that phrase to mean any alien who satisfies one of the adjectival descriptions set forth in subparagraphs (A)-(D) of paragraph (1) ("any alien who" "is inadmissible" or "is deportable" under the specified laws). In re Rojas, 23 I. & N. Dec. 117, 121 (BIA 2001). Petitioners, and now three of our colleagues, argue instead--and this is crucial to their entire argument--that the pertinent description of the aliens in paragraph (1) clearly includes as well the adverbial phrase "when the alien is released" (emphasis added). In this manner, our colleagues reason that if an alien was not detained by the Attorney General immediately "when the- 72 - alien [was] released," then that alien is not an alien "described" in paragraph (1). This attempt at deputizing an adverbial phrase into service as a description of the noun "alien" pays little heed to customary conventions of grammar and syntax. "An adverb, an adverbial phrase, or an adverbial clause may qualify several parts of speech, but a noun is not one of them." Theodore M. Bernstein, The Careful Writer, A Modern Guide to English Usage 23 (1965). Conversely, adjectives (like those in subparagraphs (A)-(D)) are "good friends of the noun." H.W. Fowler, A Dictionary of Modern English Usage 10 (Sir Ernest Gowers ed., 2d ed. 1965); see also Merriam-Webster's Collegiate Dictionary 19 (11th ed. 2012). We do not mean to say that there are never circumstances in which writers might employ an adverbial phrase in the manner employed by our colleagues. Poetic license, after all, knows few bounds. Rather, we say merely that if a straightforward reading of the text employing basic, conventional usages of grammar points directly at a given interpretation, it should take some pretty heavy lifting to reject that interpretation, much less to reject it as not even within the zone of reasonableness. Nor is grammar the only enemy of petitioners' preferred reading of the text. Structure argues against petitioners as well. After stating what the Attorney General must do to "any alien who--," paragraph (1) sets down in four separately indented and- 73 - lettered subsections the four clauses that plainly describe an alien, relegating the adverbial "when" phrase back to unlettered and unindented text. We thus not only have four adjectival clauses that obviously describe the noun "alien" and one adverbial phrase that less readily does so, but we also have a format that literally and visually sets the four descriptions apart from the adverbial phrase. This structure directly reinforces the reading of the "when" phrase as qualifying the verb "take" in the clause "[t]he Attorney General shall take into custody" rather than as describing "any alien[s]." In so observing, we do not mean to overstate the case. Our colleagues make a fair point that the statute might have been more clear had paragraph (2) referred only to subparagraphs (A)-(D). Of course, the fact that language might have been more clear--as it always could be--does not mean that it is not clear enough. See Caraco Pharm. Labs., Ltd. v. Novo Nordisk A/S, 132 S. Ct. 1670, 1682 (2012) ("[T]he mere possibility of clearer phrasing cannot defeat the most natural reading of a statute . . . ."); cf. In re Fahey, 779 F.3d 1, 6 (1st Cir. 2015) (explaining that a statute's meaning was clear even though the statutory language could not "be read as entirely excluding the possibility" that a competing--but ultimately unpersuasive--interpretation was correct). Relatedly, we note that Congress has on occasion, within the Immigration and Nationality Act ("INA"), referenced a general- 74 - subparagraph while clearly intending to refer only to the inset subclauses within that subparagraph. See, e.g., 8 U.S.C. § 1153(b)(5)(B)(i) (referencing 8 U.S.C. § 1153(b)(5)(A) but clearly intending to cross-reference only the inset clauses (i)- (iii) within (A)). We also find it significant that the language and structure of section 1226(c) as a whole reveals that Congress actually did specify which criminal aliens described in paragraph (1) may be released notwithstanding those aliens' prior commission of (A)-(D) crimes. It described those aliens in paragraph (2). And that description (of persons connected to government witnesses or investigations) plainly does not include petitioners. Cf. TRW Inc. v. Andrews, 534 U.S. 19, 28 (2001) ("Where Congress explicitly enumerates certain exceptions to a general prohibition, additional exceptions are not to be implied, in the absence of evidence of a contrary legislative intent." (quoting Andrus v. Glover Constr. Co., 446 U.S. 608, 616–617 (1980))). We have good company in concluding that it is reasonable to read section 1226(c) in this manner. In describing the statute in the first sentence of Demore, the Supreme Court stated that section 1226(c) "provides that '[t]he Attorney General shall take into custody any alien who' is removable from this country because he has been convicted of one of a specified set of crimes." Demore,- 75 - 538 U.S. at 513. As petitioners would have it, the Court should have added "and has just been released" as part of its description of the alien to whom the mandates were intended to apply. But it did not, presumably because it was focused on its recognition that Congress's goal was to end the practice of "releasing deportable criminal aliens on bond" in order to avoid what Congress decided was "an unacceptable rate of flight." Id. at 520. Of course, the Court's description of the statute was not a holding. It certainly shows, though, that a pretty good reader of statutes easily reads the language as we do. Cf. S.D. Warren Co. v. Me. Bd. of Envtl. Prot., 547 U.S. 370, 377 (2006) (looking to how the court previously tended to use the term "discharge" in dicta under the Clean Water Act). In gauging the import of the foregoing textual analysis, we must also express a reservation concerning our colleagues' interpretative methodology. At several steps in their analysis, they confront an interpretative guide that cuts against them (e.g., adverbs usually do not describe nouns, the layout of the subheadings supports a grammatical reading, the Supreme Court's short-hand summary of the statute is informative). In each case, our colleagues correctly note that the guide is not always dispositive. So far, so good. They then, however, proceed forward as if the import of those guides carries no continuing weight in the analysis and so does not undermine a conclusion that the- 76 - statute is actually plainly to the contrary. We view that import, instead, as an accumulating weight capable of being offset only by evidence that speaks directly and unambiguously to the contrary. Silence, assumptions, inferences, and ambitiously constructed lines of reasoning that were likely never within the contemplation of any drafter serve poorly as substitutes for such evidence. See Rhode Island v. Narragansett Indian Tribe, 19 F.3d 685, 698 (1st Cir. 1994) ("[L]egislative history that is in itself inconclusive will rarely, if ever, overcome the words of a statute."). This is not to say that we end our own inquiry at this point. To the contrary, we accept the notion that most statutes must be read with a sense of what Congress was trying to do, and that such a sense may be derived from knowledge gained outside the four corners of the text, keeping in mind the weighty role that the text must continue to play. We also agree with our colleagues--and with the BIA--that the statutory language is not so plain as to foreclose all extra-textual inquiry. So, for that reason, and particularly because the actual language at issue touches upon matters of both personal liberty and the control of our nation's borders, we think it reasonable to look next at the legislative history to determine whether one can say that the straightforward, grammatically conventional reading of the statute comports with a reasonable interpretation of what Congress was trying to accomplish.- 77 - **B. Legislative History** Our review of the legislative history begins with the most directly pertinent legislative history: the conference report to the IIRIRA. Regarding section 1226(c) (i.e., section 236(c) of the law), the report states in full: New section 236(c) provides that the Attorney General must detain an alien who is inadmissible under section 212(a)(2) or deportable under new section 237(a)(2). This requirement does not apply to an alien deportable under section 237(a)(2)(A)(i) on the basis of an offense for which the alien has not been sentenced to at least 1 year in prison. This detention mandate applies whenever such an alien is released from imprisonment, regardless of the circumstances of the release. This subsection also provides that such an alien may be released from the Attorney General's custody only if the Attorney General decides in accordance with 18 U.S.C. 3521 that release is necessary to provide protection to a witness, potential witness, a person cooperating with an investigation into major criminal activity, or a family member or close associate of such a witness or cooperator, and such release will not pose a danger to the safety of other persons or of property, and the alien is likely to appear for any scheduled proceeding. H.R. Rep. No. 104-828, 1996 WL 563320, at *210-11 (1996) (Conf. Rep.). It is beyond dispute that the phrase "such an alien" as used in the third sentence of the conference report refers back to the aliens who are described in the first two sentences, neither of which contains (as either adjective or adverb) any requirement- 78 - that the person be recently released. The third sentence simply tells us when the new custody mandate applies to "such an alien." It is also entirely fair to presume that the same phrase "such an alien" means the same thing in the fourth sentence's description of what the statute "also" provides for: the no-release mandate. This is, of course, simply another way of saying that the alien "described" in section 1226(c)(2)'s no-release mandate is an alien described in 1226(c)(1)(A)-(D)--the same class of alien who is subject to the custody mandate whenever released. And since petitioners were admittedly subject to the custody mandate (i.e., each is "such an alien") they are therefore subject to what section 1226(c)(2) also provides for such an alien: the no-release mandate. We recognize that our colleagues manage to read even this directly authoritative legislative history as indicating that Congress intended to leave the no-release mandate contingent on how quickly the Attorney General complied with the detention mandate. While we have much difficulty seeing this, we need only for present purposes protest that such a reading is hardly compelling. It is our colleagues, not us, who must claim a monopoly on reasonableness. We move next to the 1995 Senate Report that directly sets forth the substance of congressional concerns resulting in the enactment of the IIRIRA. S. Rep. No. 104-48 (1995). Treating the report as if it were Oz's man behind the green curtain, our- 79 - colleagues urge the reader to pay no attention to it. But the Supreme Court itself in Demore directly turned to this report for precisely the same purpose that guides us to look at the report: understanding the aims of Congress in enacting section 1226(c). See Demore, 538 U.S. at 518–21 & n.4. The Court--like us--has read this legislative history as plainly evidencing "Congress' concern that, even with individualized screening, releasing deportable criminal aliens on bond would lead to an unacceptable rate of flight." Id. at 520. For example, the Senate Report emphasized that "[u]ndetained criminal aliens with deportation orders often abscond upon receiving [a notice of removal]. . . . (This notice is humorously referred [to] by some INS personnel as the 72 hours 'run notice.')" S. Rep. No. 104-48, at 2-3; see Demore, 538 U.S. at 518-19 & n.4, 521. The data before Congress likewise supported its concern that immigration judges fared poorly in trying to predict which aliens would take flight once INS took steps to remove them. S. Rep. No. 104-48, at 2 ("Over 20 percent of nondetained criminal aliens fail to appear for deportation proceedings."). And the Senate Report's recommendation that "Congress should consider requiring that all aggravated felons be detained pending deportation" due to "the high rate of no-shows for those criminal aliens released on bond,"- 80 - S. Rep. No. 104-48, at 32 (emphasis added), directly addressed-- and is certainly entirely consistent with--this concern. Nor did Congress give any reason to think that this concern disappeared merely because the criminal alien was not detained for a period of time before deportation proceedings began. To the contrary, the "deportable criminal aliens [who] failed to appear for their removal hearings," Demore, 538 U.S. at 519, were all those aliens who were not being held in INS custody. In this respect, it is helpful to keep in mind the actual interpretation of the statute that petitioners urge. They repeatedly argue that Congress would not have been concerned about allowing immigration judges to predict flight risk for criminal aliens who have "long since returned to their communities." But their reading of the statute would mean that all criminal aliens who avoid detention

"when . . . released" would be e ntitled to a shot at convincing an immigration judge that the alien would voluntarily surrender if removal is ordered. And this would be so whether the alien has been free from prior criminal custody for a week or for five years, and no matter what the alien has done post-release. Of course, one could argue that the immigration judges will not release obvious flight risks. But that is presumably what immigration judges were trying to do before Congress concluded that it had insufficient confidence in the immigration judges' ability to make ad hoc predictions, and opted for the categorical- 81 - treatment of four groups of aliens who are most likely to be removed. To now say that the executive, merely by failing to detain a criminal alien promptly, can revive the immigration judges' ability to pick and choose who gets released on bail would be a result directly at odds with what Congress plainly sought to achieve. Cf. King v. Burwell, 135 S. Ct. 2480, 2496 (2015) (rejecting an interpretation of the Affordable Care Act that would lead to the "result that Congress plainly meant to avoid"). Nor does it help petitioners to argue that Congress's concern about recidivism is somehow inapplicable categorically for those criminal aliens who have "lived in the community" for some undefined period of time post-release. In the first place, there is no compelling evidence in the record that Congress meant section 1226(c) to apply only when both reasons for its enactment --avoiding flight and re-offense--would be served. Second, just as Congress found unacceptable the mere possibility of recidivism among this category of criminal aliens during the period between release from criminal custody and removal adjudication, there is no basis in the record for presuming that Congress felt that immigration judges would be in a position to discount that possibility merely by noting that the criminal alien had been released some time ago. The immigration judges will both lack much knowledge about what the criminal alien has been doing since release and have no ability to predict future behavior that is- 82 - materially greater than the ability found by Congress to be insufficient. The legislative record, like Conan Doyle's dog that did not bark, also conveys much by what it does not say. See Chisom v. Roemer, 501 U.S. 380, 396 & n.23 (1991). Imagine, for example, that petitioners were correct: if a criminal alien were not detained immediately upon release from prison, that alien would have a right to convince an immigration judge that the alien is not a flight risk. And, as our colleagues read the statute, this right would belong to every alien not detained upon release, whether or not the alien settled in any community, or took efforts to hide, or even went on a crime spree. If that had been Congress's aim, it is unlikely that there would be no acknowledgement of such a loophole, nor any language in the statute defining and limiting the loophole. Similarly, if the entire mandatory detention regime hinged on whether the criminal alien was detained "when . . . released," one would have expected Congress to pay some attention to defining that term. How much time is too much? What if the alien hides? What if the alien commits a new crime? What if the state prison does not cooperate, making it impossible for federal agents to know when the alien will leave state custody? There is no evidence that Congress viewed its legislation as raising such questions, all of which would have been nose-on-the-face obvious- 83 - had Congress intended the statute to be read as petitioners would have us read it. Precisely to the contrary, the entire focus was broadly and categorically on "[u]ndetained criminal aliens." See S. Rep. No. 104-48, at 2. Particularly noteworthy in this regard is the fact that

the drafters were well aware of--and concerned about--the fact that criminal aliens were avoiding detention because some state and local authorities refused to let INS know when criminal aliens were being released. See S. Rep. No. 104-48, at 16-17, 22. Yet, if petitioners are correct, Congress gave the state and local authorities hostile to Congress's aim complete ability to frustrate pursuit of that aim. Our knowledge of how Congress chooses to affect the removal process of criminal aliens in other provisions of the U.S. Code dovetails with our understanding of Congress's purpose in enacting section 1226(c). For example, Congress, in the IIRIRA, barred from eligibility for cancellation of removal any permanent resident alien convicted of an aggravated felony. 42 See Pub. L. No. 104-208, 110 Stat. 3009-594 (creating 8 U.S.C. § 1229b(a)(3)); Rojas, 23 I. & N. Dec. at 121-22. Congress also stripped courts of jurisdiction "to review any final order of removal against an

42 An alien who is "deportable by reason of having committed" an aggravated felony falls under section 1226(c)(1)(B). Compare 8 U.S.C. § 1226(c)(1)(B), with id. § 1227(a)(2)(A)(iii).- 84 - alien who is removable by reason of having committed" certain criminal offenses that are also listed as predicate offenses under section 1226(c)(1)(A)-(C). See 8 U.S.C. § 1252(a)(2)(C); Rojas,

23 I & N Dec. at 122. 43 The aliens described in (A)-(D) are therefore more likely to lose--and more likely to expect to lose --in a removal proceeding, thus increasing the incentive to flee once they are on Immigration and Customs Enforcement's ("ICE") radar. It therefore seems natural to conclude that Congress wanted these aliens to be in custody when the removal proceeding concluded, whether or not they were taken into custody right when previously released. Congress's focus in related legislation on making it more difficult for criminal aliens to successfully contest a removal order also reinforces the view that Congress aimed to deal with such aliens categorically. In saddling criminal aliens with many burdens not imposed on aliens who reside in the United States

43 The INA contains numerous other examples of ways in which Congress has made it more difficult for criminal aliens to avoid removal. For instance, in removal proceedings, lawful permanent residents convicted of crimes involving moral turpitude may not qualify for a discretionary waiver of removability, because commission of a crime of moral turpitude tolls the accrual of the seven years of residence required for cancellation of removal. See 8 U.S.C. § 1229b(d)(1). Other aliens convicted of a crime involving moral turpitude may not qualify for cancellation and adjustment to lawful permanent resident status. See id. § 1229b(b)(1)(C). Additionally, aggravated felons may not seek asylum, see id. § 1158(b)(2)(A)(ii), (b)(2)(B)(i), nor may they seek persecution-based withholding of removal if they have been sentenced to five years or more in prison, see id. § 1231(b)(3)(B).- 85 - without committing crimes viewed by Congress as especially relevant to immigration status, see supra note 43, Congress has drawn no distinction based on when the alien is detained. Evidence of living in the community for years post-release does not eliminate the legal disabilities in removal proceedings imposed by the prior commission of certain criminal acts. On the contrary, during the years preceding the IIRIRA and within the IIRIRA itself, Congress actively sought to narrow the group of criminal aliens eligible for relief based on duration of residency. For example, prior to the IIRIRA, many aliens with "a lawful unrelinquished domicile of seven consecutive years" could seek relief from removal despite their prior criminal activity. See INS v. St. Cyr, 533 U.S. 289, 295 (2001) (quoting section 212(c) of the INA, formerly codified as 8 U.S.C. § 1182(c)). This sort of relief had "great practical importance," id., and "the class of aliens whose continued residence in this country . . . depended on their eligibility for § 212(c) relief [was] extremely large, and not surprisingly, a substantial percentage of their applications" were granted, id. at 295-96. After amendments to the INA in 1990 and 1996 narrowed the availability of section 212(c) relief, the IIRIRA eliminated it and replaced it with an even narrower class of lawfully admitted permanent resident aliens who had been lawfully present for at least five years and had not been convicted of an aggravated felony. See id. at 297; 8 U.S.C. § 1229b(a).- 86 - We have also considered the language governing section 1226(c)'s effective date, IIRIRA, § 303(b)(2), 110 Stat. 3009, 3009-586, and the IIRIRA's Transition Period Custody Rules ("TPCR"), IIRIRA, § 303(b)(3), 110 Stat. at 3009-586 to -587. 44 We agree with our colleagues that such language, as part of the very statute at issue, provides a source of potential insight into the meaning of its companion terms. See Gutierrez v. Ada, 528 U.S. 250, 255 (2000). That insight runs in favor of the interpretation we adopt. Most notably, the effective date provision states that section 1226(c) "shall apply to individuals released after" the expiration of the TPCR. IIRIRA, § 303(b)(2), 110 Stat. at 3009- 586. That clause would be superfluous if petitioners were correct that the detention-without-release mandate applies only to aliens who are picked up right away, because immediate detention would be impossible for aliens who had already been released prior to the TPCR's expiration date. See Nat'l Ass'n of Home Builders v. Defs. of Wildlife, 551 U.S. 644, 669 (2007) ("[W]e have cautioned against reading a text in a way that makes part of it redundant."). While we acknowledge the Supreme Court's recent reiteration that its

44 The TPCR imposed a more permissive regime that, due to Congress's concerns about bed space shortages, governed bond determinations for two years after the IIRIRA's effective date and prior to section 1226(c)'s full implementation. See IIRIRA, § 303(b)(3), 110 Stat. at 3009-586 to -587.- 87 - "preference for avoiding surplusage constructions is not absolute," King, 135 S. Ct. at 2492 (internal quotation mark omitted), the canon provides at the very least yet another thumb to be added to grammar, structure, and legislative purpose on the scale in favor of our interpretation. 45 That thumb is particularly large in this case, where (unlike in King), Chevron applies. See King, 135 S. Ct. at 2488– 89 (declining to apply the Chevron two-step framework because if "Congress wished to assign [interpretation] to an agency, it surely would have done so expressly"). Here, we are first asked whether Congress has spoken clearly and directly to the question at issue, and second whether the BIA's interpretation is a reasonable one. The surplusage caused by petitioners' interpretation at once makes the interpretative path they walk less direct and the BIA's reading in Rojas more reasonable. Cf. Nat'l Credit Union Admin. v. First Nat'l Bank & Tr. Co., 522 U.S. 479, 501 (1998) (rejecting, under Chevron step one, agency's interpretation in part because it made "the phrase 'common bond' surplusage").

45 We agree with the actual holding in Saysana v. Gillen, 590 F.3d 7, 18 (1st Cir. 2009), that section 1226(c) does not apply to aliens released from custody for their (A) through (D) offenses prior to the IIRIRA's effective date. To the extent that one might glean from Saysana any inferences concerning the issue presented here for the first time, such inferences would not be binding on our en banc court. See United States v. Gonzalez-Arimont, 268 F.3d 8, 13 (1st Cir. 2001).- 88 - Even putting to one side the surplusage ramification, the TPCR provides no support for petitioners' position because it simply raises the same interpretative question that section 1226(c) poses: do the custody and no-release mandates during the transition period apply if there is a delay in detaining the alien? Our colleagues nevertheless attempt to glean from the TPCR two points of support that warrant our consideration. First, they point out that the transition rules set forth in the TPCR contain language stating that, should the Attorney General as anticipated invoke the transition rules, § 1226(c) will apply only to persons released after expiration of the transition period. The rules contain no similar provision stating that the mandates in the transition rules themselves apply only to aliens released after the transition rules become effective. This means, our colleagues reason, that under our interpretation the breadth of the mandate's duty imposed on the Attorney General under the permanent rules of section 1226(c) would be "less sweeping than the supposedly more flexible TPCR mandate's bar had been" even though the TPCR was intended to accommodate the Attorney General's need to ramp up resources. The way to fix this "anomalous" result, our colleagues argue, is to read the TPCR's bar on releasing aliens to apply only to those taken into custody "when . . . released." And if one reads the TPCR that way, by analogy one should read section 1226(c) that way. Anomaly cured.- 89 - In this manner, our colleagues imagine a problem that does not exist in order to advocate a solution that is not required. There is no need to interpret the TPCR in this manner to make its duties "less sweeping" than those imposed by section 1226(c). The TPCR, unlike section 1226(c), expressly allows the Attorney General to release any detained aliens who fall into two of the four groups of aliens described in both the TPCR and section 1226(c). Our colleagues offer no evidence at all establishing that the effect of this categorical exclusion does not swamp whatever burden might arise as a result of the theoretical possibility that the Attorney General within the brief two-year transition period might pick up criminal aliens who had not been released from criminal custody during that period. More fundamentally, our colleagues' premise that language in the TPCR need be rendered superfluous in order to cure a perceived "anomaly" between the TPCR and section 1226(c) incorrectly presumes that it was possible to start up a new regime, with differing transition rules, and not have some "anomalies." For example, what was to be done with an alien who was released from prison during the transition period, and who then moved for bail after the expiration of the transition period? Under the language of the transition rules--and under either interpretation of section 1226(c) proffered in this case--such a person would suddenly have a shot at bonded release that he might not have had- 90 - if he had moved for bail before the transition period had expired (i.e., the section 1226(c) detention mandates would be "less sweeping"). See In re Adeniji, 22 I. & N. Dec. 1102, 1110-11 (BIA 1999). Certainly such an anomaly provides no license to re-write section 1226(c). It does, however, make clear that some such anomalies arise inevitably from the need to have some arbitrary cut-offs for implementing new programs. Second, our colleagues complain that, in some instances, the BIA's reading of section 1226(c) would have "de-linked" or "misaligned" the custody and no-release aspects of section 1226 if the TPCR transition rules had not been invoked because the clause in the TPCR limiting section 1226(c) as a whole to persons released after the TPCR became effective would not have been triggered. As an example, our colleagues point to a suspected terrorist described in subsection 1226(c)(1)(D) who has never been imprisoned and who is roaming the streets. Under the BIA's interpretation, the Attorney General would reserve the ability to decide whether to arrest such a person because the custody mandate would not have been triggered by a prior release. Once the Attorney General decided the suspected terrorist should be detained, under the BIA's reading of section 1226(c)(2), as it would apply had the transition period not been implemented, no immigration judge would have the discretion to release the alien unless the alien prevailed in the removal proceeding. Our colleagues apparently think this is an- 91 - obviously unsound result, and that Congress must have intended that immigration judges could second guess the Attorney General and order such an alien released. How one reads Congress's manifest unhappiness with the predictive failure of immigration judges as supporting such a conclusion puzzles us. 46 Our colleagues also lean hard on the meaning they derive from section 1226(c)'s predecessors. We agree with the BIA's position in Rojas that, while none of the other predecessor provisions shed helpful light on the issue to be decided in thiscase, the post-1991, pre-AEDPA version of the custody and norelease mandates is instructive. Rojas, 23 I & N. Dec. at 123- 24. That version, embodied in section 242(a)(2) of the INA following the 1990 and 1991 amendments, 47 provided that:

46 Our colleagues point out that there is no legislative history suggesting that Congress was more hostile to the discretion of immigration judges in determining whether to grant bonded release to a criminal alien than to the discretion of immigration enforcement in determining whether to bring a criminal alien into immigration custody in the first place. But this is immaterial. Given that we apply Chevron deference, it is incumbent on our colleagues to demonstrate that it clearly lay outside of Congress's intent to adopt a statutory scheme that would not require immigration enforcement to track down and detain each and every criminal alien, including the low-level narcotics offender, but that would allow immigration enforcement to rest assured that efforts to detain those criminal aliens who do represent enforcement priorities would not go for naught due to the miscalculation of an immigration judge at the alien's bond hearing. 47 Immigration Act of 1990, § 504, Pub. L. No. 101-649, 104 Stat. 4978, 5049; Miscellaneous and Technical Immigration and Naturalization Amendments of 1991, § 306(a)(4), Pub. L. No. 102- 232, 105 Stat. 1733, 1751 (effective as if included in the 1990 Act).- 92 - (A) The Attorney General shall take into custody any alien convicted of an aggravated felony upon release of the alien (regardless of whether or not such release is on parole, supervised release, or probation, and regardless of the possibility of rearrest or further confinement in respect of the same offense). Notwithstanding [the equivalent of section 1226(a)] . . . but subject to subparagraph (B), the Attorney General shall not release such felon from custody. (B) The Attorney General may not release from custody any lawfully admitted alien who has been convicted of an aggravated felony, either before or after a determination of deportability, unless the alien demonstrates to the satisfaction of the Attorney General that such alien is not a threat to the community and that the alien is likely to appear before any scheduled hearings. INA § 242(a)(2) (1991) (emphasis added). Under subparagraph (B) (the equivalent of section 1226(c)(2)), whether the alien is subject to that statute's mandate limiting release prior to his hearing turns entirely on whether the alien was convicted of an aggravated felony, "unless" the alien is able to demonstrate that he is not a bond risk. There is nothing in that version of the statute that even remotely suggests that a lapse in establishing custody removes an alien from the scope of subparagraph (B)'s coverage. And notably absent from subparagraph (B) is any mention of subparagraph (A) or its "upon release" language (i.e., the "when . . . released" clause's equivalent). This is a problem for our colleagues and petitioners because, once again, that textual reference point is the only hook- 93 - they latch on to in concluding that the description of aliens subject to the no-release mandate includes a timing element. Simply put, the language of the most long-standing version of the no-release mandate prior to the IIRIRA does not appear to contain any of the ambiguity that section 1226(c) arguably possesses with respect to the relevance of the timing of release. None of the language in the predecessor provisions to which our colleagues point contains this level of clarity on this key point. And if our colleagues' position that Congress has never sought to alter the relationship between the custody and no-release mandates is correct, this would seem to doom their argument. Our colleagues point, instead, only to an off-point BIA opinion, Matter of Eden, 20 I. & N. Dec. 209 (BIA 1990), as reflecting the pre-IIRIRA law that Congress sought to preserve. But the question of whether a delay in detaining a criminal alien eliminated the Attorney General's obligation to deny bond once the alien was detained was not even raised as an issue in Eden. Rather, the case involved an alien who had been taken into immigration custody while on "special parole" as part of his criminal sentence. The question posed was whether subjecting such a person to mandatory immigration custody without bond was inconsistent with "Congress' decision to allow [an] alien serving time in [a] state or local facility to finish out that time before the Service assumes responsibility for his incarceration." Id. at 214.- 94 - It is true that, under Rojas's reasoning, the BIA perhaps could have reached the same result in Eden merely by saying that once a criminal alien was detained, he could not be granted bond regardless of whether he had yet been released from prior custody. Even under that approach, though, the BIA would have had an interest in clarifying the scope of the Attorney General's statutorily mandated duty to detain a criminal alien--and, namely, in clarifying whether conceiving of a duty on the Attorney General to detain a person too soon (i.e., during the course of a prior sentence) ran up against the congressional intent expressed through the 1988 legislation's "upon release" provision. In any event, the simpler point is that there is no holding in Eden, either express or implied, that addresses the issue posed here. 48 Compounding their attempt to glean a holding--much less settled law--from Eden, our colleagues then simply misread the House report to the 1990 legislation that revised the clause "upon completion of the alien's criminal sentence" to read "upon release of the alien (regardless of whether or not release is on parole, supervised release, or probation . . . .)." Rightly or wrongly, the report plainly states that Congress was concerned that "[a]t least one immigration judge has ruled that an aggravated felon who has been paroled by the sentencing court continues to serve his

48 Not even the dissent in Rojas cites Matter of Eden.- 95 - 'sentence' [and therefore] INS has no authority to incarcerate this alien until his period of parole has ended." H.R. Rep. No. 101-681, pt. 1, at 148 (1990), as reprinted in 1990 U.S.C.C.A.N. 6472, 6554 (emphasis added). In short, Congress was fearful that its mandate to take criminal aliens into custody without bond upon completion of the sentence was being construed as divesting INS of any authority to detain an alien while the alien was on parole. Restoring that authority implied a "link" to the no-release mandate only in the obvious sense that any elimination of INS's authority even to take a person into custody obviously frustrates any mandate that the person be kept in custody. Nothing in this sort of logical link in any way implies (much less compels) a conclusion that the custody and the no-release mandates are "linked" in the sense that our colleagues' analysis requires. To the contrary, the fact that Congress wanted even those criminal aliens who would otherwise be subject to parole reporting and supervision to be detained during their removal proceedings would seem to cut against our colleagues' assumption that a brief period of unsupervised living in the community eliminated the need for detention. This type of error (presuming that any reference to "immediate" detention without bond implies that a delay in detention makes a bond possible) pervades our colleagues' entire discussion of the legislative record. When we see Congress repeatedly emphasizing that the gove rnment must take criminal- 96 - aliens into custody "when," "upon," or "immediately upon" their release, and then not release them, we see no implied loophole. Rather, we see an increasingly urgent expectation that criminal aliens should be found in custody when the removal decision issues. We stress, too, that even if one were to ignore these defects in our colleagues' survey of the legislative history, the most one ends up with are efforts to infer an answer to the question at hand from statements made in addressing other issues where the resolution of those other issues did not require or even call upon a degree of precision that would be necessary to confirm the force of the inference. And in each instance, the actual resolution of the issue at hand is completely compatible with the BIA's conclusion in Rojas. Inferences of this type, whether reasonable or not, seem to us to fall far short of the "clear" legislative record one should require to end the inquiry at Chevron step one. Turning their focus from the 1991 amendment and its predecessors, our colleagues repeat their error in claiming that we should presume that, in enacting the IIRIRA, Congress was aware of the fact that "district courts . . . treated the retained 'upon release' clause [of AEDPA] as if it conditioned the retained 'such felon clause.'" Supra at 38-39. Our colleagues cite five district court cases as constituting this "existing law" of which Congress was supposedly aware. Three are actually holdings that address retroactivity under AEDPA. Montero v. Cobb, 937 F. Supp. 88 (D.- 97 - Mass. 1996); Villagomez v. Smith, No. C96-1141C, 1996 WL 622451 (W.D. Wa. July 31, 1996) (unpublished); DeMelo v. Cobb, 936 F. Supp. 30 (D. Mass. 1996), vacated, 108 F.3d 328 (1st Cir. 1997) (per curiam). As for the fourth, we sincerely doubt that Congress managed to dredge up an obscure unpublished opinion from the Southern District of Texas, which to this day remains difficult to locate. See In re Reyes, Case No. B-94-80 (S.D. Tex. May 31, 1996). The fifth, Grodzki v. Reno, 950 F. Supp. 339 (N.D. Ga. 1996), is arguably on point, but was not issued until September 20, 1996, just ten days before the already drafted IIRIRA was passed into law. See Pub. L. No. 104-208, 110 Stat. 3009. In any event, even were all five cases squarely apposite, five district court opinions could not establish the type of "settled judicial construction" as to which we presume congressional awareness. See United States v. Powell, 379 U.S. 48, 55 n.13 (1964) (four lower court opinions, including two by circuit courts, insufficient). In sum, against a legislative backdrop thick with indications that Congress aimed to ensure that criminal aliens not go free prior to the conclusion of their removal proceedings, our colleagues stake their reading of the statute on one off-point BIA ruling, one district court decision issued ten days prior to the IIRIRA's enactment, and the supposedly anomalous results derived from reading section 1226(c) in conjunction with what our colleagues themselves describe as "an ancillary and potentially- 98 - never operative clause in the TPCR," supra at 30-31 n.23. In view of the foregoing, one might argue that section 1226(c)'s legislative history actually compels a finding that the straightforward, grammatically conventional reading of the statute must be correct. Instead, tempering our confidence in our own interpretative analysis, we need opine at this point only that the legislative history is not so clearly to the contrary as to compel a finding that "Congress has directly spoken to the precise question at issue" (much less that it spoke with the intent our colleagues claim is clearly apparent). Chevron, 467 U.S. at 842. **C. Our Colleagues' Conclusion Falls Short of the Mark** We have explained our disagreement with our colleagues' argument that no reasonable jurist can read the phrase "as described in paragraph 1" as not incorporating into paragraph 2 the phrase "when released . . . ." Even if we are wrong, though, we agree with the Second, Third, Fourth, and Tenth Circuits that the Attorney General's delay in detaining petitioners does not render the no-release mandate inapplicable. Our sister circuits have explained why this is so under the loss-of-authority rubric. See Lora, 2015 WL 6499951, at *8; Olmos, 780 F.3d at 1324–26; Sylvain, 714 F.3d at 157–61; Hosh, 680 F.3d at 381–83. We prefer to reframe the point as a matter of interpreting the text consistently with the purpose manifest in the text. The key point here is that even if the no-release mandate of paragraph (c)(2)- 99 - applied by its terms only to persons who have been released from criminal custody, there is no good reason to say also that it applies only when the Attorney General complies with the custody mandate by detaining the criminal aliens right when they are

released. Consider the following example that we have crafted so that its substance and evident purpose invite the type of reading that our colleagues insist is applicable to section 1226(c). (1) Please give an especially thorough watering to any plant that is: (A) a sunflower, or (B) a hibiscus when it is planted for the garden show. (2) Do not let a plant described in paragraph (1) go any day without water unless you are certain that it is dead. Under the scenario posed by this example, we would agree that it is reasonable to read the reference to plants "described in paragraph (1)" as indicating not all sunflower or hibiscus plants, but rather as indicating sunflower or hibiscus plants that are newly planted for the garden show. This is because our knowledge that certain new plantings need prompt and regular watering gives us a clue for resolving any ambiguity created by the structure and awkward syntax of the mandates. Nevertheless, even in this example designed to welcome the type of reading that our colleagues give to section 1226(c), it simply does not follow that the mandate of section (2) is also- 100 - contingent upon prompt compliance with the mandate of section (1). No reasonable person would let the plants in question continue to go without water merely because impediment or neglect unduly postponed the first watering. Of course, this conclusion, too, follows in great part from an assumption that the principal purpose of the mandates is to keep the new plants alive. In the case of section 1226(c), an analogous (and actual) purpose is manifest in the legislative history discussed in this opinion and in Demore. In repeatedly and even more broadly expressing dissatisfaction with criminal aliens not being in custody when removal is ordered, Congress did not order the Attorney General to detain such aliens only if she chose to do so right away. Rather, we read section 1226(c) as ordering the Attorney General to detain such persons, and to do it right away. The question whether the Attorney General complied with that mandate right away--like the question whether the plants were watered promptly when planted--is simply an exogenous and independent fact that is not part of the description of those to whom either mandate applies. 49

49 Our colleagues suggest that our distinction between exogenous and endogenous characteristics cuts too fine. We will simplify. Section 1226(c)(1), under any reading, both creates a duty and describes a group of people as to whom that duty must be carried out. We see how section 1226(c)(2)'s reference to a person "described in" section 1226(c)(1) could reasonably be understood to refer to a member of the delineated group as to whom the duty- 101 - **D. The Constitutional Avoidance Canon** Since our colleagues rest their decision on Chevron's first step, they do not reach the constitutional avoidance argument principally relied upon by petitioners and by the panel opinion we vacated prior to hearing this appeal en banc. See Warger v. Shauers, 135 S. Ct. 521, 529 (2014) (constitutional avoidance canon "has no application in the absence of . . . ambiguity" (omission in original) (internal quotation marks omitted)); Olmos, 780 F.3d at 1321 (citing Warger in declining to consider the canon for purposes of Chevron step one). Because we disagree with our colleagues' conclusion that no reasonable person can read the statute other than as they read it, we explain why the constitutional avoidance canon, even if it may be appropriately applied at Chevron step two, 50 does not remove the BIA's decision

exists. But we simply fail to see how a reasonable reader construes the cross-reference as referring to a member of the delineated group as to whom the duty was in fact immediately executed. Section 1226(c)(1), which creates a forward-facing duty, is of course powerless to "describe" the class of people as to whom that duty will in fact be carried out. 50 An en banc panel of the Ninth Circuit determined that the constitutional avoidance canon "plays no role in the second Chevron inquiry." Morales-Izquierdo v. Gonzales, 486 F.3d 484, 493 (9th Cir. 2007) (en banc). The Tenth Circuit in Olmos cited that opinion approvingly, Olmos, 780 F.3d at 1323 & n.2, but also appeared to reject the merits of petitioner's constitutional avoidance argument in its step two analysis, id. at 1324. As the D.C. Circuit has noted (in a case also cited in Olmos), the Supreme Court has at least once indicated that the "canon of constitutional avoidance trumps Chevron deference." Nat'l Mining Ass'n v. Kempthorne, 512 F.3d 702, 711 (D.C. Cir. 2008) (citing Edward J.- 102 - in Rojas from the range of permissible interpretations requiring

deference. 51 Petitioners' basic claim in favor of applying the canon is that a statutory command to detain aliens such as petitioners who had peacefully resided in the community for years after their release from criminal custody would raise serious constitutional due process concerns. In accepting this claim, the panel opinion relied on what seems to us to be a doubly flawed reading of Justice Kennedy's concurring opinion in Demore. First, the panel viewed Justice Kennedy's concurrence as limiting the Demore majority's rationale for upholding section 1226(c). See Castañeda, 769 F.3d at 39 & n.4. The panel appeared to be (erroneously) applying the Supreme Court's Marks principle, which instructs that "[w]hen a fragmented Court decides a case and no single rationale explaining the result enjoys the assent of five Justices, the holding of the Court may be viewed as that position taken by those Members who concurred in the judgments on

DeBartolo Corp. v. Fla. Gulf Coast Bldg. & Constr. Trades Council, 485 U.S. 568, 575 (1988)). Since we see no basis for the canon's application regardless, we decline to take any position on the canon's precise relevance to the Chevron analysis. 51 The Third and Fourth Circu its did not address the constitutional avoidance argument that petitioners press here. See Sylvain, 714 F.3d 150; Hosh, 680 F.3d 375. The Second and Tenth Circuits rejected it, see Lora, 2015 WL 6499951, at *9 n.20; Olmos, 780 F.3d at 1322–24, but the Tenth Circuit noted in a footnote that "[c]onstitutional considerations could become greater when the gap in custody is considerably longer than six days." Olmos, 780 F.3d at 1324 n.5.- 103 - the narrowest grounds." Marks v. United States, 430 U.S. 188, 193 (1977) (internal quotation marks omitted). But Justice Kennedy's concurrence in Demore explicitly stated that he joined the majority's "careful opinion . . . in full," Demore, 538 U.S. at 533 (Kennedy, J., concurring), so nothing therein limits the majority's rationale for upholding section 1226(c). Nor does Justice Kennedy's concurrence provide persuasive authority in favor of petitioners' due process argument. That concurrence expressed no reservation at all, constitutional or otherwise, about the amount of time that passed between the moment an alien became released and the moment of the alien's detention. Rather, Justice Kennedy wrote separately to address a concern (which we share) about the amount of time an alien spends in immigration detention while he waits for his removal proceeding. See id. at 532 ("[S]ince the Due Process Clause prohibits arbitrary deprivations of liberty, a lawful permanent resident alien such as respondent could be entitled to an individualized determination as to his risk of flight and dangerousness if the continued detention became unreasonable or unjustified." (emphasis added)). The concurrence's three citations to Zadvydas v. Davis, 533 U.S. 678 (2001), a case dealing the constitutional limits upon the duration of post-removal-period detention (and the only court case cited by the concurrence), support that limited reading.- 104 - To be sure, the Demore majority addressed only the general application of section 1226(c) to an alien who had committed an (A)-(D) offense, withou t considering the precise constitutional consideration--the length of time an alien managed to avoid detention post-release--that petitioners now claim requires a resolution in their favor. 52 But for the following reasons, we view this as a distinction without a difference with respect to whether the delay in commencing detention experienced by petitioners raises constitutional concerns. Petitioners' argument rests on the premise that, once a law-breaking alien has been out of custody for several years, one can no longer regard him as presenting a sufficiently heightened risk of danger or flight, even once the alien finds out ICE now wants to deport him on grounds that will be hard to successfully contest. Neither petitioners nor the vacated panel opinion cite any controlling authority for this proposition, and we have great difficulty accepting this view of flight risk as a matter of common sense. See Olmos, 780 F.3d at 1323 ("[W]e do not abandon Chevron deference at the mere mention of a possible constitutional problem." (alteration in original) (quoting Kempthorne, 512 F.3d at 711)). It seems to us that Congress could have--and did--

52 Perhaps since he was detained the day after his release, Kim v. Ziglar, 276 F.3d 523, 526 (9th Cir. 2002), the petitioner in Demore made no argument about the timing of his release.- 105 - reasonably regard this group of aliens as categorically posing a flight risk because their commission of the designated crimes makes it highly likely that they will be deported if ICE comes knocking. Hence, there is little to lose by trying to hide, especially once a removal order issues. See S. Rep. No. 104-48, at 2-3 ("Undetained criminal aliens with deportation orders often abscond upon receiving a final notification [of removal]. . . . Too often, as one frustrated INS official told the Subcommittee staff, only the stupid and honest get deported."). The incentive to flee peaks once the criminal alien knows that ICE has decided to come after him. And while the incentive may be depressed while ICE ignores the alien, once ICE manifests an intention to proceed forthwith, the incentive to flee before the deportation proceeding ends would seem to be unrelated to any delay in making that manifestation. 53 The view of petitioners and of the vacated panel opinion on this point is effectively that, if there is an individual fact showing a person poses a lesser risk of flight or danger (e.g., has been living in a community for years), then that person is

53 Imagine Aliens A and B in a detention center, each having committed the same section 1226(c) offense, and each similar in all ways, except ICE detained Alien A one day after release from state custody, and Alien B four years after release. Now imagine that each was suddenly released pending completion of his removal hearing. We can see no reason why we can say that, as a matter of constitutional law, Congress could not have reasonably viewed A and B as posing similar flight risks during the period between release and removal hearing.- 106 - constitutionally entitled to a bail hearing. See Castañeda, 769 F.3d at 47-48 ("Mandatory detention of individuals such as the petitioners appears arbitrary on its face."). This view fundamentally pushes back on Congress's ability (affirmed in Demore) to say categorically that criminal aliens should not have the ability to flee while awaiting the reasonably prompt conclusion of their deportation hearings. 54 We would therefore reject it. We note, finally, that petitioners have raised no argument based on the duration of their detention, nor have they produced evidence that the BIA's interpretation of section 1226(c) will subject them to systemic delays or otherwise prolong the length of their detention prior to a hearing. Cf. Demore, 538 U.S. at 532 (Kennedy, J., concurring). As of the time that the Supreme Court last considered the statute, "in 85% of the cases in which aliens [were] detained pursuant to § 1226(c), removal proceedings [were] completed in an average time of 47 days and a median of 30 days." Demore, 538 U.S. at 529. To the extent that the Attorney General would attempt to use section 1226(c) to detain

54 Many statutes and cases in the criminal sentencing area give equal weight to prior criminal convictions irrespective of whether the individual was recently released from custody. A person qualifies, for example, for mandatory life imprisonment as a "violent felon" whether his predicate convictions occurred last year or six years ago. See 18 U.S.C. § 3559(c)(1). Accordingly, we cannot say that Congress could not regard the danger risk as materially reduced merely because the alien has spent some time out of custody.- 107 - persons for materially more extended durations, see Lora, 2015 WL 6499951, at *12, we offer in this opinion no blessing of such detentions. Rather, we opine only that the constitutional arguments raised by petitioners here do not make impermissible the BIA's interpretation of section 1226(c), either facially or as applied to petitioners. **II. Conclusion** For the foregoing reasons, we would hold that petitioners have the characteristics of "an alien described in" section 1226(c)(1), and that the Attorney General is correct in concluding that she therefore lacks the discretion to grant them a bond hearing. 55

55 Petitioners do not argue that they qualify for the witness protection exception in section 1226(c)(2).
