Saris, C.J.
*209INTRODUCTION
In this class action, Plaintiffs challenge the constitutionality of mandatory detention of noncitizens with certain criminal convictions who have been detained for more than six months during removal proceedings without the opportunity for a bond hearing pursuant to 8 U.S.C. § 1226(c). Plaintiffs represent a class of "[a]ll individuals who are or will be detained within the Commonwealth of Massachusetts or the State of New Hampshire pursuant to 8 U.S.C. § 1226(c) for over six months and have not been afforded an individualized bond or reasonableness hearing." Reid v. Donelan, No. 13-30125-PBS, 2018 WL 5269992, at *8 (D. Mass. Oct. 23, 2018). Both Plaintiffs and the Government have moved for summary judgment on whether mandatory detention of the class members under 8 U.S.C. § 1226(c) for over six months violates the Fifth Amendment Due Process Clause or the Eighth Amendment Excessive Bail Clause. After hearing, the Court ALLOWS IN PART and DENIES IN PART Plaintiffs' motion for summary judgment (Docket No. 453) and ALLOWS IN PART and DENIES IN PART the Government's motion for summary judgment (Docket No. 455).
In summary, the Court holds and declares as follows: First, as the Government agrees, mandatory detention without a bond hearing under 8 U.S.C. § 1226(c) violates due process when an noncitizen's individual circumstances render the detention unreasonably prolonged in relation to its purpose in ensuring the removal of deportable noncitizens with criminal records. Second, the determination of whether mandatory detention without a bond hearing has become unreasonably prolonged is a fact-specific analysis. The most important factor in determining whether detention has become unreasonably prolonged is the length of the detention. The Court rejects Plaintiffs' request that the Court impose a bright-line six-month rule on the ground that it is unsupported by the record and the caselaw. Third, in the unusual instances when mandatory, categorical detention lasts for more than one year during agency removal proceedings, excluding any dilatory tactics attributable to the noncitizen, the delay is likely to be unreasonable. This one-year period reflects the Government's own regulations and policies, which aim to complete removal proceedings in no more than nine months, and statistics showing that most removal proceedings take less than one year. However, detention of under a year may be unreasonably prolonged if the matter just lingers on the immigration court or Board of Immigration Appeals ("BIA") docket.
Fourth, a noncitizen subject to mandatory detention without a bond hearing under § 1226(c) must bring a habeas petition in federal court to challenge his detention as *210unreasonably prolonged. If the court agrees, the individual is entitled to a bond hearing before an immigration judge at which the Government bears the burden of proving that he is either dangerous by clear and convincing evidence or a risk of flight by a preponderance of the evidence. If the Government demonstrates that the individual is dangerous or a risk of flight, for example if he has a serious criminal record, he is not entitled to release. Fifth, in making its release determination, the immigration court may not impose excessive bail, must evaluate the individual's ability to pay in setting bond, and must consider alternative conditions of release such as GPS monitoring that reasonably assure the safety of the community and the individual's future appearances.
PROCEDURAL HISTORY
The Court assumes familiarity with the complex procedural posture of this case from its October 23, 2018 memorandum and order and only briefly summarizes the relevant background. See Reid, 2018 WL 5269992, at *1-3.
On July 1, 2013, Plaintiff Mark Anthony Reid filed a petition for writ of habeas corpus and complaint for injunctive relief that raised statutory and constitutional claims challenging mandatory detention under § 1226(c). On January 9, 2014, the court (Ponsor, J.) granted Reid's individual habeas petition. Reid v. Donelan, 991 F. Supp. 2d 275, 282 (D. Mass. 2014), aff'd, No. 14-1270, 2018 WL 4000993 (1st Cir. May 11, 2018). Following its earlier decision in Bourguignon v. MacDonald, 667 F. Supp. 2d 175 (D. Mass. 2009), the court held that § 1226(c) "include[d] a 'reasonableness' limit on the length of time an individual can be detained without an individualized bond hearing" to avoid due process concerns with indefinite detention, Reid, 991 F. Supp. 2d at 279. The court evaluated two approaches to implementing this reasonableness requirement: an automatic bond hearing once mandatory detention exceeds six months ("six-month rule") or a bond hearing only when mandatory detention has become unreasonable as analyzed on a case-by-case basis ("individualized reasonableness rule"). See id. at 279-82. The court determined that Reid was entitled to a bond hearing under either approach but suggested it would adopt the six-month rule. See id. at 279.
On February 10, 2014, the court (Ponsor, J.) certified the following class under Federal Rule of Civil Procedure 23(b)(2) : "All individuals who are or will be detained within the Commonwealth of Massachusetts pursuant to 8 U.S.C. § 1226(c) for over six months and have not been afforded an individualized bond hearing." Reid v. Donelan, 297 F.R.D. 185, 194 (D. Mass. 2014). Three months later, the court (Ponsor, J.) awarded summary judgment and a permanent injunction to the class on the basis of its holding that § 1226(c) includes a requirement for a bond hearing after six months of mandatory detention. See Reid v. Donelan, 22 F. Supp. 3d 84, 88-89, 93-94 (D. Mass. 2014), vacated, No. 14-1270, 2018 WL 4000993 (1st Cir. May 11, 2018). The court also held that due process did not require that the Government bear the burden of proof at the class members' bond hearings, let alone by clear and convincing evidence. Id. at 92-93.
On appeal, the First Circuit agreed that "categorical, mandatory, and indeterminate detention raises severe constitutional concerns" and that the canon of constitutional avoidance necessitated reading a bond hearing requirement into § 1226(c). Reid v. Donelan, 819 F.3d 486, 494 (1st Cir. 2016), withdrawn, No. 14-1270, 2018 WL 4000993 (1st Cir. May 11, 2018). Disagreeing with the district court, however, the First Circuit held that Supreme Court *211precedent required it to adopt the individualized reasonableness rule. See id. at 495-98. It instructed district courts evaluating the reasonableness of § 1226(c) detention without a bond hearing to "examine the presumptions upon which [mandatory detention] was based (such as brevity and removability)" and consider "the total length of the detention; the foreseeability of proceedings concluding in the near future ...; the period of the detention compared to the criminal sentence; the promptness (or delay) of the immigration authorities or the detainee; and the likelihood that the proceedings will culminate in a final removal order." Id. at 500. Based on this holding, the First Circuit vacated the grant of summary judgment to Plaintiffs on the class claims. Id. at 501. Since its decision raised questions as to the continued propriety of class certification, the court declined to address Plaintiffs' cross-appeal challenging the district court's holding that due process does not require the Government to bear the burden of proof at a bond hearing. See id. The court noted, however, that Plaintiffs raised "a bevy of weighty constitutional arguments" concerning the procedural protections required at a bond hearing. Id.
Two months later, the Supreme Court granted certiorari in Jennings v. Rodriguez, a class action in the Ninth Circuit also challenging mandatory detention under § 1226(c). See --- U.S. ----, 136 S. Ct. 2489, 195 L.Ed.2d 821 (2016) (mem.). The First Circuit stayed this lawsuit pending resolution of Jennings. On February 27, 2018, the Supreme Court held that the explicit language in § 1226(c) requiring mandatory detention during removal proceedings barred courts from invoking the canon of constitutional avoidance to read an implicit requirement for bond hearings into the statute. Jennings v. Rodriguez, --- U.S. ----, 138 S. Ct. 830, 846-47, 200 L.Ed.2d 122 (2018). Because the Ninth Circuit did not decide if such mandatory detention is constitutional, the Court declined to rule on that question. See id. at 851.
Shortly thereafter, the First Circuit withdrew its previous opinion in this case. See Reid, 2018 WL 4000993, at *1. In a summary decision, it affirmed the district court's judgment for Reid individually, vacated the judgment for the class, and remanded the case for reconsideration of the certification order. Id. After the case was reassigned on remand, this Court determined that continued certification of the class was proper. See Reid, 2018 WL 5269992, at *8. While adoption of the individualized reasonableness rule would require an analysis of the circumstances of each class member's detention, the class still raised the common question of "whether the Due Process Clause or Excessive Bail Clause requires that they at least have the chance to plead their case after six months at an individualized bond or reasonableness hearing." Id. at *5. The Court declined to address whether 8 U.S.C. § 1252(f)(1) would bar a classwide permanent injunction because it could, at a minimum, issue a declaratory judgment establishing class members' right to a bond or reasonableness hearing. Id. at *6. After an opportunity for discovery, both Plaintiffs and the Government now move for summary judgment.
STATISTICAL BACKGROUND ON § 1226(c) DETENTION
The Court allowed for limited discovery concerning the average and median detention times for individuals subject to mandatory detention under 8 U.S.C. § 1226(c). The parties did not submit any deposition testimony but present dueling statistics about § 1226(c) detention. Plaintiffs state that the median length of detention for released or removed class members *212(whose detention has ended and who, per the class definition, were detained for at least 180 days) was 363.5 days, with 25% detained for fewer than 253 days and 25% detained for more than 561.5 days. Dkt. No. 460-1 ¶ 8. The two longest periods of detention were 1,541 and 1,291 days. Id. Non-class members detained under § 1226(c) (i.e., for less than 180 days) were held for a median of 98 days, with 25% detained for 60 days or fewer. Id. ¶ 11. Plaintiffs do not provide information on the average period of § 1226(c) detention overall. They do add, however, that 27% of class members detained under § 1226(c) before implementation of Judge Ponsor's 2014 injunction obtained relief from removal or termination of their removal proceedings. Dkt. No. 387-5 ¶ 9.
The Government provided the Court with data on the duration of removal proceedings in the Boston and Hartford Immigration Courts for individuals detained under § 1226(c) over the past twenty years. Dkt. No. 415-1 at 9-14. The Government emphasizes that immigration court proceedings for only 3.8% of aliens lasted more than a year, but this figure does not account for the duration of an appeal to the BIA. From the Government's charts, the Court has calculated that removal proceedings, including any appeal to the BIA, but not including any petition for review to the circuit court, lasted longer than one year for 5.8% of aliens detained under § 1226(c) over the past five years.1 ibr.US_Case_Law.Schema.Case_Body:v1">See id. The median completion time for removal proceedings at the immigration court level over the past five years was around 40 days in non-appealed cases and three months in cases that were ultimately appealed to the BIA. Id. ¶ 18. In 2018, the median pendency of an appeal to the BIA was around four months. Id. ¶ 24. Nearly 90% of non-appealed cases were completed within six months. Id. ¶ 18. Only 22% of § 1226(c) detainees were granted relief or had their removal proceedings terminated in 2018 in the Boston Immigration Court. Id. ¶ 20.
The parties agree that close to half of the class members that received a bond hearing pursuant to Judge Ponsor's 2014 injunction were given an opportunity for release. Immigration judges set bond for 37 of the 104 class members (36%) and released 13 others under orders of supervision or recognizance (13%). See Dkt. No. 460-1 ¶¶ 14-15; Dkt. No. 467 ¶¶ 5-6.
The Government has also submitted the criminal histories of all of the members of the class. This information reveals that the class is comprised of immigrants with a wide range of criminal backgrounds. Some class members have only one conviction for a nonviolent offense. See, e.g., Dkt. No. 459-1 at 33 (gambling); id. (identity theft). A number have been convicted of drug offenses. See, e.g., id. at 21 (two convictions for drug possession); id. at 22 (one conviction for selling marijuana). Others have lengthy criminal histories with a number of convictions for violent crimes. See, e.g., id. at 10 (multiple convictions for burglary and aggravated assault);
*213id. at 23-24 (two convictions for assault and one for kidnapping).
Mark Reid, the original class representative, was convicted in 2002 and 2010 of drug trafficking and possession and conspiracy to commit burglary. U.S. Immigration and Customs Enforcement ("ICE") detained him on November 13, 2012 and initiated removal proceedings. At the bond hearing Judge Ponsor ordered for him in January 2014, an immigration judge released him on bond. Reid's removal proceedings are still ongoing, as the BIA has remanded his case back to the immigration judge three times. The immigration judge determined that Reid has not committed an aggravated felony, and Reid is currently challenging whether his convictions are crimes involving moral turpitude and is claiming eligibility for asylum, withholding of removal, and relief under the Convention Against Torture. In March and April 2019, Reid was charged in two separate incidents with, inter alia, threatening, breach of the peace, and possession of cocaine.
Robert Williams, another class representative, pled guilty to drug possession and weapons charges. ICE served Williams with a Notice to Appear and took him into custody on December 6, 2017. An immigration judge ordered him removed and denied his application for cancellation of removal, and the BIA dismissed his appeal. He was removed on October 25, 2018 while his petition for review of the BIA order was pending at the Second Circuit.
Leo Felix Charles, the final class representative, was convicted of drug trafficking and first-degree assault. After completing his term of imprisonment, he was detained by ICE on February 2, 2018. An immigration judge terminated his deferral of removal under the Convention Against Torture, which he had received in 2003, and the BIA dismissed his appeal. Charles filed a petition for review of the BIA dismissal, and the Second Circuit stayed his removal on December 11, 2018 pending resolution of his petition. ICE released Charles from custody on February 14, 2019.
DISCUSSION
I. Statutory Background
8 U.S.C. § 1226 governs the detention of aliens2 during removal proceedings. Jennings, 138 S. Ct. at 837. The Government may generally release an alien on bond or conditional parole pending a decision on his removability. 8 U.S.C. § 1226(a). However, 8 U.S.C. § 1226(c) "carves out a statutory category of aliens who may not be released." Jennings, 138 S. Ct. at 837. Under § 1226(c), the Government "shall take into custody any alien" who is inadmissible or deportable based on a conviction for "certain crimes of moral turpitude, controlled substance offenses, aggravated felonies, firearm offenses, or acts associated with terrorism." 8 U.S.C. § 1226(c)(1) (emphasis added); Gordon v. Lynch, 842 F.3d 66, 67 n.1 (1st Cir. 2016). The crimes that serve as predicates for mandatory detention under § 1226(c) vary widely from simple drug possession, 8 U.S.C. § 1227(a)(2)(B)(i), to violent crimes such as rape and murder, 8 U.S.C. § 1101(a)(43)(A).
A criminal alien is subject to mandatory detention whether or not he is taken into immigration custody as soon as he is released from criminal custody for his underlying offense. See *214Nielsen v. Preap, --- U.S. ----, 139 S. Ct. 954, 965, 203 L.Ed.2d 333 (2019).3 The Government may release such an alien only for witness protection purposes and only if the alien shows he is not a danger to the community or a risk of flight. 8 U.S.C. § 1226(c)(2). The statute does not provide a right to a bond hearing, but an alien who believes he does not have the requisite criminal conviction to qualify for mandatory detention may challenge his classification in Joseph hearings. Preap, 139 S. Ct. at 971 n.8 (citing Matter of Joseph, 22 I. & N. Dec. 799 (BIA 1999) ).
Congress enacted § 1226(c) in the 1990s in response to the difficulty the Government faced in removing deportable criminal aliens. See Demore v. Kim, 538 U.S. 510, 521, 123 S.Ct. 1708, 155 L.Ed.2d 724 (2003). Congress had evidence that the Government was unable to remove deportable criminal aliens in large part because of its "broad discretion" to release aliens on bond during removal proceedings and the "severe limitations on funding and detention space, which ... affected its release determinations." Id. at 519, 123 S.Ct. 1708. Between one-in-five and one-in-four aliens with criminal records released on bond failed to appear at their removal hearings. See id. at 519-20, 123 S.Ct. 1708. In enacting § 1226(c), Congress determined that "detention of criminal aliens during their removal proceedings might be the best way to ensure their successful removal." Id. at 521, 123 S.Ct. 1708.
The Supreme Court has decided two cases concerning § 1226(c) that are relevant to Plaintiffs' constitutional claims. First, in Demore v. Kim, the Court rejected an alien's facial due process challenge to mandatory detention under § 1226(c). 538 U.S. at 522-23, 530, 123 S.Ct. 1708. The Court emphasized that "[d]etention during removal proceedings is a constitutionally permissible part of that process" and Congress may detain aliens based on statutory presumptions rather than relying on individualized dangerousness and flight risk determinations for each alien. Id. at 526, 531, 123 S.Ct. 1708. As the Court explained, "when the Government deals with deportable aliens, the Due Process Clause does not require it to employ the least burdensome means to accomplish its goal." Id. at 528, 123 S.Ct. 1708. Accordingly, mandatory detention under § 1226(c) was a permissible exercise of Congress's immigration authority to ensure that aliens removable for serious criminal offenses would neither commit new crimes nor abscond before execution of their removal orders. See id. at 517-20, 528, 123 S.Ct. 1708.
The Court relied on statistics showing that the vast majority of aliens subject to mandatory detention were detained for no more than five months and noted that the petitioner had been detained himself for only six months. Id. at 529-31, 123 S.Ct. 1708. Unfortunately, these statistics turned out to be erroneous. See Jennings, 138 S. Ct at 869 (Breyer, J., dissenting) (explaining that the statistics the Court relied on in Demore were incorrect and that "[d]etention normally lasts twice as long as the Government then said it did"). The Court therefore emphasized that § 1226(c) detention was permissible for "the brief period necessary for ... removal proceedings." Demore, 538 U.S. at 513, 123 S.Ct. 1708 ; see also id. at 531, 123 S.Ct. 1708 (upholding the petitioner's detention "for the limited period of his removal *215proceedings"). In a concurrence, Justice Kennedy, who provided the fifth vote for the majority, noted that due process might require "an individualized determination as to [an alien's] risk of flight and dangerousness if the continued detention became unreasonable or unjustified." Id. at 532, 123 S.Ct. 1708 (Kennedy, J., concurring).
Second, as discussed above, the Court held in Jennings v. Rodriguez that § 1226(c) unambiguously "mandates detention of any alien falling within its scope" and permits detention to end "prior to the conclusion of removal proceedings only if the alien is released for witness-protection purposes." 138 S. Ct. at 847 (internal quotation omitted). Because of the statute's clarity, the Court reversed the Ninth Circuit's use of the canon of constitutional avoidance to read an implicit requirement for an individualized bond hearing once an alien is detained pursuant to § 1226(c) for six months. See id. at 836, 839. The Court declined to address whether this interpretation of § 1226(c) violated due process. Id. at 851.
II. Due Process Clause
In its brief and at the hearing, the Government concedes that mandatory detention under § 1226(c) without a bond hearing violates the Due Process Clause when it becomes unreasonably prolonged in relation to its purpose in ensuring the removal of deportable criminal aliens. This concession accords with the pre-Jennings decisions of the six circuit courts, including the First Circuit, that read a reasonableness limitation into § 1226(c) via the canon of constitutional avoidance. See Sopo v. U.S. Att'y Gen., 825 F.3d 1199, 1212-13 (11th Cir. 2016) (collecting cases), vacated, 890 F.3d 952 (11th Cir. 2018). While Demore upheld the constitutionality of mandatory detention under § 1226(c) for the brief period of time reasonably necessary to effectuate the removal of a deportable criminal alien, it did not address the lengthy period of detention at issue in this case, which Plaintiffs point out lasted over four years for one class member. Indeed, Justice Kennedy recognized in Demore that due process would require "an individualized determination as to [an alien's] risk of flight and dangerousness if the continued detention became unreasonable or unjustified." 538 U.S. at 532, 123 S.Ct. 1708 (Kennedy, J., concurring). And Jennings rejected the use of the canon of constitutional avoidance to read a reasonableness limitation into § 1226(c) because of the statute's unambiguous language, not because prolonged, categorical detention under § 1226(c) does not raise due process concerns. 138 S. Ct. at 836 ; see also id. at 851 (declining to address the underlying due process question).
This Court therefore holds that mandatory detention under § 1226(c) without a bond hearing violates due process when it becomes unreasonably prolonged in relation to its purpose in ensuring the removal of deportable criminal aliens. See Reid, 819 F.3d at 498-99.
The more difficult question is how to determine when a criminal alien's mandatory detention becomes unreasonably prolonged. Before Jennings, circuit courts developed two approaches. The Second and Ninth Circuits adopted a six-month rule requiring an automatic bond hearing for any alien detained under § 1226(c) for more than six months. See Lora v. Shanahan, 804 F.3d 601, 616 (2d Cir. 2015), vacated, --- U.S. ----, 138 S. Ct. 1260, 200 L.Ed.2d 415 (2018) ; Rodriguez v. Robbins, 715 F.3d 1127, 1138 (9th Cir. 2013), abrogated by Jennings, --- U.S. ----, 138 S. Ct. 830, 200 L.Ed.2d 122 (2018). The First, Third, Sixth and Eleventh Circuits utilized an individualized reasonableness rule requiring *216a fact-specific analysis of whether an alien's detention had become unreasonable. See Sopo, 825 F.3d at 1215 ; Reid, 819 F.3d at 498 ; Diop v. ICE/Homeland Sec., 656 F.3d 221, 234 (3d Cir. 2011), abrogated by Jennings, --- U.S. ----, 138 S. Ct. 830, 200 L.Ed.2d 122 (2018) ; Ly v. Hansen, 351 F.3d 263, 271 (6th Cir. 2003), abrogated by Jennings, --- U.S. ----, 138 S. Ct. 830, 200 L.Ed.2d 122 (2018).
Plaintiffs urge the Court to adopt the six-month rule and grant each class member a bond hearing, while the Government advocates for the individualized reasonableness rule. In the event the Court adopts the individualized reasonableness rule, Plaintiffs ask the Court to order the Government to provide each class member a "reasonableness hearing" in immigration court at which the Government bears the burden of demonstrating that the alien's continued mandatory detention without a bond hearing is reasonable. The Government contends that each class member must raise his fact-specific challenge to the reasonableness of his mandatory detention via an individual habeas petition in federal court. Finally, Plaintiffs argue that due process requires a number of procedural protections for criminal aliens who are granted bond hearings, namely that the Government bear the burden of proving dangerousness and/or risk of flight by clear and convincing evidence.
A. Six-Month Rule or Individualized Reasonableness Rule?
As an initial matter, Demore implicitly forecloses adoption of the six-month rule. See Reid, 819 F.3d at 497. The alien in Demore spent six months in immigration detention before the district court granted his habeas petition. 538 U.S. at 530-31, 123 S.Ct. 1708. Neither the majority opinion nor Justice Kennedy's concurrence expressed any concern that his detention had become unreasonable by virtue of hitting the six-month mark, although the Court was not directly presented with this question. Plaintiffs point out that the statistics concerning the average length of § 1226(c) detention on which the Court relied were erroneous and that "[d]etention normally lasts twice as long as the Government then said it did," Jennings, 138 S. Ct at 869 (Breyer, J., dissenting), but they do not explain why this fact renders the six-month rule required as a matter of due process. Plaintiffs assert that the median length of detention for released or removed class members (who, per the class definition, were detained for at least 180 days) was 363.5 days, while non-class members detained under § 1226(c) (i.e., for less than 180 days) were detained for a median of 98 days. Dkt. No. 460-1 ¶¶ 8, 11. These data do not show that six months is the outer limit of a reasonable period for the Government to complete removal proceedings.
The six-month rule is also inconsistent with the Supreme Court's opinion in Jennings. The Supreme Court expressly rejected the six-month rule as a matter of statutory interpretation, noting that "nothing in [ § 1226(c) ] imposes a 6-month time limit on detention without the possibility of bail." Jennings, 138 S. Ct. at 851. The Court also emphasized that "due process is flexible, ... and it calls for such procedural protections as the particular situation demands." Id. at 852 (quotation omitted). An alien's mandatory detention without a bond hearing becomes unreasonably prolonged when it no longer reasonably serves to ensure the swift removal of a deportable criminal alien. This determination is inherently fact-specific. Cf. Barker v. Wingo, 407 U.S. 514, 521, 92 S.Ct. 2182, 33 L.Ed.2d 101 (1972) (recognizing in the speedy trial context that courts "cannot definitely say how long is too long in a *217system where justice is supposed to be swift but deliberate"). Section 1226(c) detention does not necessarily stop reasonably serving its statutory purpose at six months. The six-month rule has practical advantages in avoiding inconsistent and burdensome individual determinations, but it does not account for the fact-specific nature of the due process inquiry. See Reid, 819 F.3d at 497-98.
Since the Supreme Court decided Jennings in 2018, the vast majority of district courts have adopted the individualized reasonableness rule as a matter of due process. See, e.g., Cabral v. Decker, 331 F. Supp. 3d 255, 260 (S.D.N.Y. 2018) ; Dryden v. Green, 321 F. Supp. 3d 496, 502 (D.N.J. 2018). The Court has identified only one decision that has utilized the six-month rule post- Jennings. See Rodriguez v. Nielsen, No. 18-cv-04187-TSH, 2019 U.S. Dist. LEXIS 4228, at *18 (N.D. Cal. Jan. 7, 2019).
The six-month rule fails to account for actions taken by an alien that may extend his pre-removal detention. The Government reports that the median completion time of removal proceedings in cases appealed to the BIA in 2018 was just under nine months. See Dkt. No. 415-1 ¶ 24. As the Court explained in Demore, § 1226(c) detention does not violate due process simply by virtue of the length of time it takes for an alien to effectuate an appeal. See 538 U.S. at 530 n.14, 123 S.Ct. 1708. A bright-line six-month rule would effectively grant a bond hearing to aliens who appealed to the BIA even where those proceedings were moving forward in a timely manner. See Reid, 819 F.3d at 500 n.4 (recognizing that mandatory detention does not become unreasonable during the pendency of a promptly adjudicated appeal by the alien but explaining that "there may come a time when promptness lapses"). The six-month rule also does not account for dilatory tactics by the alien that extend removal proceedings. Plaintiffs argue that an immigration court could consider such tactics at a bond hearing, but the only relevant considerations in determining the suitability of bond are dangerousness and risk of flight. See In re Guerra, 24 I. & N. Dec. 37, 40 (BIA 2006), abrogated on other grounds by Pensamiento v. McDonald, 315 F. Supp. 3d 684 (D. Mass. 2018).
Zadvydas v. Davis, 533 U.S. 678, 121 S.Ct. 2491, 150 L.Ed.2d 653 (2001), does not compel, or even support, the conclusion that due process requires an automatic bond hearing after six months of mandatory detention under § 1226(c). In Zadvydas, the Supreme Court addressed whether 8 U.S.C. § 1231(a)(6) authorized the Government to detain an alien subject to a final order of removal for more than the ninety-day statutory period to secure his removal. 533 U.S. at 682, 121 S.Ct. 2491. Because "indefinite detention of [such] aliens ... would raise serious constitutional concerns" if they were never removed, the Court read § 1231(a)(6) to "contain an implicit 'reasonable time' limitation." Id. "[T]o guide lower court determinations," the Court adopted six months after entry of the final order of removal as the "presumptively reasonable period of detention." Id. at 701, 121 S.Ct. 2491. After six months, "once the alien provides good reason to believe that there is no significant likelihood of removal in the reasonably foreseeable future, the Government must respond with evidence sufficient to rebut that showing." Id.
The Zadvydas Court did not simply order release (or a bond hearing) for any alien detained under § 1231(a)(6) for six months after entry of a removal order. Instead, the Court required the Government to present evidence after six months of post-removal-order detention that removal was still reasonably foreseeable for *218the alien being detained, i.e., that detention still reasonably served the purpose of the statute. See id. Zadvydas therefore undermines the notion that the reasonableness of immigration detention can be determined by a bright-line rule without some individualized analysis of each alien's circumstances.
Furthermore, the question at issue here, namely whether unreasonably prolonged, categorical detention during removal proceedings violates due process, presents different considerations than the issue in Zadvydas. See Demore, 538 U.S. at 527, 123 S.Ct. 1708 (recognizing that the circumstances in Zadvydas were "materially different" from § 1226(c) detention). "[P]ost-removal-period detention, unlike detention pending a determination of removability ..., has no obvious termination point." Zadvydas, 533 U.S. at 697, 121 S.Ct. 2491 ; see also Demore, 538 U.S. at 529, 123 S.Ct. 1708 (explaining that § 1226(c) detention has "a definite termination point"). In Zadvydas, the Supreme Court adopted a bright-line presumption to give some metric to determine "how much longer towards eternity could be considered 'reasonable.' " Reid, 819 F.3d at 496. Removal proceedings have a reasonably foreseeable endpoint.
Plaintiffs contend that mandatory detention becomes unreasonable after six months because an immigration court can continue to detain any alien found to be dangerous or a risk of flight at a bond hearing, which protects the Government's interests in flight and danger prevention. Under this reasoning, mandatory detention under § 1226(c) would violate due process from the start, a conclusion the Supreme Court rejected in Demore. The Government need not "employ the least burdensome means to accomplish its goal" of ensuring the removal of deportable criminal aliens and may rely on "reasonable presumptions and generic rules" to determine whom to detain. Demore, 538 U.S. at 526, 528, 123 S.Ct. 1708 (quotation omitted).
Plaintiffs challenge the congressional presumption that criminal aliens are likely to be dangerous or risks of flight, but they have presented no evidence on point. And Congress implemented § 1226(c) based on statistics showing that released criminal aliens were committing new offenses and absconding. See id. at 518-20, 123 S.Ct. 1708.
Plaintiffs also point to the Sixth Amendment's requirement of a jury trial for any crime punishable by a term of imprisonment of more than six months. See Baldwin v. New York, 399 U.S. 66, 69, 90 S.Ct. 1886, 26 L.Ed.2d 437 (1970). The Supreme Court adopted this six-month rule based on "the existing laws and practices in the Nation" with regard to jury trials. Id. at 70, 90 S.Ct. 1886 (quoting Duncan v. Louisiana, 391 U.S. 145, 161, 88 S.Ct. 1444, 20 L.Ed.2d 491 (1968) ). Plaintiffs provide no reason why this historically based six-month cutoff should apply to the materially different context of immigration detention, especially given Congress's unique authority to legislate with regard to aliens. See Demore, 538 U.S. at 521, 123 S.Ct. 1708. And while Zadvydas imposed a version of the six-month rule based on its historical understanding "that Congress previously doubted the constitutionality of detention for more than six months," 533 U.S. at 701, 121 S.Ct. 2491 (citing United States v. Witkovich, 353 U.S. 194, 77 S.Ct. 779, 1 L.Ed.2d 765 (1957) ), the case it cited for this proposition also involved post-removal-order detention, see Witkovich, 353 U.S. at 194, 77 S.Ct. 779. Plaintiffs present no historical justification for the six-month rule in the context of detention pending removal proceedings.
*219For these reasons, the Court holds that mandatory detention under § 1226(c) without a bond hearing violates due process when an alien's individual circumstances render the detention unreasonably prolonged in relation to its purpose in ensuring the removal of deportable criminal aliens. Because mandatory detention under § 1226(c) "is premised upon the alien's presumed deportability and the government's presumed ability to reach the removal decision within a brief period of time," Reid, 819 F.3d at 499 (citing Demore, 538 U.S. at 531, 123 S.Ct. 1708 (Kennedy, J., concurring)), the reasonableness of a criminal alien's mandatory detention depends on the strength of these presumptions, id. at 500. "As the actualization of these presumptions grows weaker or more attenuated, the categorical nature of the detention will become increasingly unreasonable." Id. The First Circuit held that the following nonexclusive factors are relevant in determining the reasonableness of continued mandatory detention:
the total length of the detention; the foreseeability of proceedings concluding in the near future (or the likely duration of future detention); the period of the detention compared to the criminal sentence; the promptness (or delay) of the immigration authorities or the detainee; and the likelihood that the proceedings will culminate in a final removal order.
Id.
The total length of the detention is the most important factor. See Sopo, 825 F.3d at 1217 (describing this factor as "critical"). To provide guidance in determining the reasonableness of prolonged mandatory detention under § 1226(c), the Court concludes, based on the record and the Government's own policies, that such detention is likely to be unreasonable if it lasts for more than one year during removal proceedings before the agency, excluding any delays due to the alien's dilatory tactics.4 ibr.US_Case_Law.Schema.Case_Body:v1">See id. ("[A] criminal alien's detention without a bond hearing may often become unreasonable by the one-year mark ...."); Chavez-Alvarez v. Warden York Cty. Prison, 783 F.3d 469, 476-78 (3d Cir. 2015) (recognizing that mandatory detention under § 1226(c) becomes unjustified around the one-year mark unless the alien engages in delay tactics), abrogated by Jennings, --- U.S. ----, 138 S. Ct. 830, 200 L.Ed.2d 122 (2018). The Executive Office for Immigration Review ("EOIR") has set a goal that immigration courts complete 85% of removal cases involving detained aliens within sixty days of the filing of a Notice to Appear, James R. McHenry III, Director of EOIR, Memorandum on Case Priorities and Immigration Court Performance Measures 3 (2018), https://www.justice.gov/eoir/page/file/1026721/download, and an agency regulation requires the Board of Immigration Appeals ("BIA") to adjudicate appeals from the immigration court within six months absent "exigent circumstances," 8 C.F.R. § 1003.1(e)(8)(i). It is reasonable to expect EOIR to complete removal proceedings within one year for most aliens. In fact, the Government's data show that, over the past five years, the agency completed removal proceedings for all but 5.8% of aliens detained under § 1226(c) within a year.5
*220This one-year period is not a bright line. Periods of detention directly attributable to an alien's dilatory tactics should not count in determining whether detention has exceeded the one-year mark. The Court also does not exclude the possibility that an alien's individual circumstances would render mandatory detention of less than one year unreasonable if the Government unreasonably delays or the case languishes on a docket. The one-year period simply recognizes that, based on EOIR's own goals and statistics, the agency should reasonably be able to complete removal proceedings for most aliens within one year.
The Court's refusal to import the six-month rule from Zadvydas into the context of mandatory detention under § 1226(c) does not prevent the adoption of a presumption that mandatory detention exceeding one year is unreasonable. As noted above, the six-month rule in Zadvydas provided a metric to determine how long toward an unforeseeable endpoint (the possible execution of a final removal order) could be considered reasonable. See Reid, 819 F.3d at 496. Under Zadvydas, an alien subject to a final order of removal cannot challenge his detention until the six-month period has elapsed. See 533 U.S. at 701, 121 S.Ct. 2491. By contrast, an alien subject to mandatory detention under § 1226(c) may bring an individual habeas petition at any point. The one-year presumption simply acknowledges that, given EOIR's own goals and statistics, detention for longer than a year is likely to be unreasonably prolonged.
Once an alien's mandatory detention has become unreasonably prolonged in violation of due process, he is entitled to a bond hearing before an immigration judge, not immediate release. At the bond hearing, an immigration judge will assess the alien's dangerousness and risk of flight. The Court recognizes the Government's concern about the extensive criminal records of many members of the class and emphasizes that an immigration judge is under no obligation to release a criminal alien deemed to be dangerous or a risk of flight under the burden and standard of proof described below. Indeed, when Judge Ponsor's 2014 injunction was in effect, more than half of the class members were denied bond. Aliens convicted of certain relatively minor, nonviolent offenses (like simple drug possession or gambling), however, are subject to mandatory detention under § 1226(c), and just under half of the class members granted bond hearings were released on supervision or offered bond. Already tasked with holding bond hearings for aliens detained under § 1226(a), immigration judges are capable of determining which criminal aliens are dangerous or risks of flight.
B. Reasonableness Hearings or Individual Habeas Petitions?
As an alternative to the six-month rule, Plaintiffs argue that due process requires a "reasonableness hearing" before the immigration *221court for any criminal alien detained under § 1226(c) for more than six months at which the Government must bear the burden of showing that the alien's continued categorical detention remains reasonable. If the immigration court determines that mandatory detention has become unreasonable, Plaintiffs submit, it must hold a bond hearing. Plaintiffs' suggestion for reasonableness hearings before the immigration court is derived from a footnote in the First Circuit's withdrawn opinion in this case. See Reid, 819 F.3d at 502 n.5 ("[W]e have no occasion to consider here whether another petitioner might be able to challenge the individualized reasonableness of his continued categorical detention before the immigration courts rather than the federal courts."). The Government responds that the proper mechanism for a criminal alien to challenge his mandatory detention as unreasonable is via an individual habeas petition in federal court. I agree.
The Government argues that providing every alien detained under § 1226(c) for six months with a reasonableness hearing would overwhelm the already overburdened immigration courts. Moreover, the Government raises a more fundamental concern: the immigration court's lack of jurisdiction to adjudicate the constitutional question of when mandatory detention under § 1226(c) becomes unreasonable. Administrative agencies generally do not adjudicate questions concerning the constitutionality of congressional statutes. See Johnson v. Robison, 415 U.S. 361, 368, 94 S.Ct. 1160, 39 L.Ed.2d 389 (1974). Accordingly, "it is settled that the immigration judge and [the BIA] lack jurisdiction to rule upon the constitutionality of the" Immigration and Nationality Act ("INA"). Matter of C-, 20 I. & N. Dec. 529, 532 (BIA 1992) ; see also Hinds v. Lynch, 790 F.3d 259, 263 n.4 (1st Cir. 2015) ("The BIA is without jurisdiction to adjudicate purely constitutional issues ...." (quotation omitted)). Determining that a criminal alien's mandatory detention has become unreasonable under the Due Process Clause is the equivalent of holding that § 1226(c) is unconstitutional as applied to that alien, a constitutional judgment about a federal statute that immigration courts and the BIA cannot adjudicate. While requiring federal courts to adjudicate individual habeas petitions does impose a burden on the judiciary, "federal courts have the institutional competence to make fact-specific determinations, and they have great experience applying reasonableness standards." Sopo, 825 F.3d at 1217.
The Court's holding that the proper mechanism for a criminal alien to challenge his mandatory detention without a bond hearing is via an individual habeas petition does not mean that the Government has no responsibility to ensure that criminal aliens are not subject to unreasonably prolonged mandatory detention. Indeed, the Department of Justice issued regulations establishing a review process for aliens detained under 8 U.S.C. § 1231(a)(6) after Zadvydas. See 8 C.F.R. §§ 241.4, 241.13 - 14 ; see also Bonitto v. Bureau of Immigration & Customs Enf't, 547 F. Supp. 2d 747, 752-53 (S.D. Tex. 2008) (explaining the "Post Order Custody Review" procedures and process for an alien detained under § 1231(a)(6) to request release).
While the Court urges ICE to establish similar procedures for ensuring criminal aliens are not subject to unreasonably prolonged mandatory detention without a bond hearing, the Government has explained that no such administrative procedures currently exist. An individual criminal alien must therefore bring an individual habeas petition if he believes his *222detention has become unreasonably prolonged.
C. Procedural Protections at Bond Hearings
For a criminal alien whose mandatory detention has become unreasonable, thus entitling him to a bond hearing before the immigration court, Plaintiffs argue that due process requires that the Government prove the alien's dangerousness or risk of flight by clear and convincing evidence. The Government claims Plaintiffs are barred from raising this argument by the doctrines of collateral estoppel and the law of the case because the court (Ponsor, J.) held in its 2014 judgment for the class in this case that the alien should bear the burden of proof. See Reid, 22 F. Supp. 3d at 92-93. However, "it is hornbook law that '[a] vacated judgment has no preclusive force either as a matter of collateral or direct estoppel or as a matter of the law of the case.' " Jackson v. Coalter, 337 F.3d 74, 85 (1st Cir. 2003) (alteration in original) (quoting No E.-W. Highway Comm., Inc. v. Chandler, 767 F.2d 21, 24 (1st Cir. 1985) ). The First Circuit vacated the 2014 judgment for the class, Reid, 2018 WL 4000993, at *1, so Plaintiffs may relitigate the burden of proof issue.
1. Burden of Proof
In Pensamiento v. McDonald, this Court held that due process requires that the Government bear the burden of proof at bond hearings for non-criminal aliens detained under § 1226(a). 315 F. Supp. 3d 684, 692 (D. Mass. 2018), appeal dismissed, 911 F.3d 866 (1st Cir. 2018). Plaintiffs ask the Court to extend this holding to bond hearings provided to criminal aliens detained under § 1226(c) when mandatory detention becomes unreasonable. Many courts have done so, both before Jennings as a matter of statutory interpretation, see, e.g., Lora, 804 F.3d at 616 ; Diop, 656 F.3d at 235, and after Jennings as a matter of due process, see, e.g., De Oliveira Viegas v. Green, 370 F. Supp. 3d 443, 449 (D.N.J. 2019) ; Hechavarria v. Whitaker, 358 F. Supp. 3d 227, 239-40 (W.D.N.Y. 2019) ; Portillo v. Hott, 322 F. Supp. 3d 698, 709 (E.D. Va. 2018). The Court agrees that the status of § 1226(c) detainees as criminal aliens does not alter the conclusion that due process requires that the burden of proof fall on the Government at their bond hearings.
Section § 1226(c) embodies a reasonable presumption within Congress's authority that removable criminal aliens are more likely than other removable aliens to be risks of flight or dangerous. See Demore, 538 U.S. at 526, 123 S.Ct. 1708. As the Government concedes, though, once a criminal alien's detention becomes unreasonably prolonged in violation of due process, this presumption no longer mandates categorical detention. The alien is then held pursuant to the Government's discretionary authority to detain during removal proceedings under § 1226(a).6 And when "the sole procedural *223protections available to the alien are found in administrative proceedings" in which the alien bears the burden of proof without significant judicial review, prolonged detention violates due process. Zadvydas, 533 U.S. at 692, 121 S.Ct. 2491 ; see also Foucha v. Louisiana, 504 U.S. 71, 81-82, 112 S.Ct. 1780, 118 L.Ed.2d 437 (1992) (finding unconstitutional a state statute placing the burden of proof to justify release on an individual civilly committed after being found not guilty by reason of insanity).
The Government points to language in both Jennings and Preap that it claims requires that the alien bear the burden of proof. See Preap, 139 S. Ct. at 959-60 (explaining that agency precedent places the burden of proof on the alien at a § 1226(a) bond hearing); Jennings, 138 S. Ct. at 847-48 (rejecting the Ninth Circuit's allocation of the burden of proof to the Government as a matter of statutory interpretation because "[n]othing in § 1226(a)'s text ... even remotely supports the imposition of" this requirement). Both decisions addressed questions of statutory interpretation involving § 1226(c), and neither addressed whether due process requires the Government to bear the burden of proof. These decisions simply reflect how agency precedent currently allocates the burden of proof.7 Neither Jennings nor Preap throws this Court's due process holding in Pensamiento into doubt. See Portillo, 322 F. Supp. 3d at 709 n.9 (rejecting the argument that Jennings "ma[de] clear that the burden must remain with the alien" because the Court "focused on the protections required by the statute and did not reach the constitutional question"); Cortez v. Sessions, 318 F. Supp. 3d 1134, 1146-47 (N.D. Cal. 2018) (declining to find that Jennings reversed the Ninth Circuit's earlier determination in Singh v. Holder, 638 F.3d 1196 (9th Cir. 2011), as to the burden and standard of proof at a bond hearing); see also Guerrero-Sanchez v. Warden York Cty. Prison, 905 F.3d 208, 224 n.12 (3d Cir. 2018) (placing the burden of proof on the Government at a bond hearing for an alien detained under 8 U.S.C. § 1231(a)(6) post- Jennings ).
Nor does Zadvydas suggest that a criminal alien should bear the burden of proof at a bond hearing. The Supreme Court did place the initial burden on a detained alien subject to a final removal order to show that there is "good reason to believe that there is no significant likelihood of removal in the reasonably foreseeable future" to justify release from detention. Zadvydas, 533 U.S. at 701, 121 S.Ct. 2491. But the ultimate burden falls on the Government to provide "evidence sufficient to rebut that showing." Id. While Zadvydas did not address the burden of proof at a bond hearing, it is consistent with placing the burden of proof on the Government at a criminal alien's bond hearing after the alien demonstrates that his detention has become unreasonably prolonged. See Pensamiento, 315 F. Supp. 3d at 692.
*224Finally, the Government points out that § 1226(c)(2), which permits the release of a criminal alien for witness protection purposes, places the burden on the alien to prove that he is not dangerous or a risk of flight. See 8 U.S.C. § 1226(c)(2). But § 1226(c)(2) codifies an exception to a reasonable and constitutional period of mandatory detention.8 The provision is not relevant in determining the constitutionally required burden of proof in the far different context of mandatory detention that has become unreasonably prolonged under the Due Process Clause.
2. Standard of Proof
Plaintiffs argue that due process requires that the Government justify continued detention of a criminal alien at a bond hearing with clear and convincing evidence of his dangerousness and/or risk of flight. They point to a slew of circuit and district court cases imposing a clear and convincing standard of proof on the Government both before and after Jennings and for bond hearings for aliens held under a range of immigration detention statutes. See, e.g., Guerrero-Sanchez, 905 F.3d at 224 n.12 ; Lora, 804 F.3d at 616 ; Rodriguez, 715 F.3d at 1135 ; Calderon-Rodriguez v. Wilcox, 374 F. Supp. 3d 1024, 1032 n.8 (W.D. Wash. 2019) ; Darko v. Sessions, 342 F. Supp. 3d 429, 435-36 (S.D.N.Y. 2018). In Pensamiento, this Court declined to adopt the clear and convincing standard but did not rule out the possibility that it is required by due process. See 315 F. Supp. 3d at 693.
The Court holds that due process requires the Government to prove an alien's dangerousness by clear and convincing evidence at a bond hearing. The Supreme Court has "upheld preventive detention based on dangerousness only when limited to specially dangerous individuals and subject to strong procedural protections." Zadvydas, 533 U.S. at 691-92, 121 S.Ct. 2491. As such, civil commitment of a mentally ill individual requires proof by clear and convincing evidence of his dangerousness to himself or others. See Foucha, 504 U.S. at 80, 112 S.Ct. 1780 ; Addington v. Texas, 441 U.S. 418, 431-32, 99 S.Ct. 1804, 60 L.Ed.2d 323 (1979). The fact that immigration detention aims to ensure the removal of deportable aliens does not justify a lower standard of proof for dangerousness because "civil commitment for any purpose constitutes a significant deprivation of liberty" that requires due process protection. Singh, 638 F.3d at 1204 (emphasis in original) (quoting Addington, 441 U.S. at 425, 99 S.Ct. 1804 ). While due process does not necessarily entitle aliens to the same rights as citizens, see Demore, 538 U.S. at 522, 123 S.Ct. 1708, the Supreme Court in Zadvydas indicated that the requirement for strong procedural protections before an individual is detained for dangerousness applies to citizens and aliens alike, see 533 U.S. at 690-92, 121 S.Ct. 2491.
But the Court is not persuaded that due process requires that the Government prove an alien's risk of flight by more than a preponderance of the evidence. Although the Supreme Court has imposed a clear and convincing standard in a number of civil contexts, see, e.g., Addington, 441 U.S. at 431-32, 99 S.Ct. 1804 (civil commitment for the mentally ill); Woodby v. INS, 385 U.S. 276, 286, 87 S.Ct. 483, 17 L.Ed.2d 362 (1966) (deportation); Chaunt v. United States, 364 U.S. 350, 353, 81 S.Ct. 147, 5 L.Ed.2d 120 (1960) (denaturalization), none of these contexts involves *225considerations of risk of flight. The most comparable context is criminal pretrial detention, and under the Bail Reform Act of 1984, which the Supreme Court upheld in United States v. Salerno, 481 U.S. 739, 755, 107 S.Ct. 2095, 95 L.Ed.2d 697 (1987), the Government must only prove a defendant's risk of flight by a preponderance of the evidence to justify his detention, see United States v. Patriarca, 948 F.2d 789, 793 (1st Cir. 1991). An alien in removal proceedings is not entitled to more procedural protections under the Due Process Clause than a pretrial criminal detainee. Cf. Demore, 538 U.S. at 522, 123 S.Ct. 1708 ("Congress may make rules as to aliens that would be unacceptable if applied to citizens."). Given the reasonable concern about risk of flight that prompted Congress to enact § 1226(c), see id. at 517-21, 123 S.Ct. 1708, due process requires only that the Government prove an alien's risk of flight by a preponderance of the evidence to justify his detention at a bond hearing.
3. Alternatives to Detention and Ability to Pay
Finally, due process requires that an immigration court consider both an alien's ability to pay in setting the amount of bond and alternative conditions of release such as GPS monitoring that reasonably assure the safety of the community and the criminal alien's future appearances.9 See Hernandez v. Sessions, 872 F.3d 976, 1000 (9th Cir. 2017) (requiring consideration of these factors for non-criminal aliens detained under 8 U.S.C. § 1226(a) ); Abdi v. Nielsen, 287 F. Supp. 3d 327, 338 (W.D.N.Y. 2018) (same for arriving aliens detained under 8 U.S.C. § 1225(b) ). This requirement guarantees that the decision to continue to detain a criminal alien is reasonably related to the Government's interest in protecting the public and assuring appearances at future proceedings. See Hernandez, 872 F.3d at 990. The Government contends that immigration judges do not have the authority to consider alternative conditions of release, but the BIA has concluded otherwise. See Matter of Garcia-Garcia, 25 I. & N. Dec. 93, 98 (BIA 2009) (citing 8 U.S.C. § 1226(a)(2)(A) and 8 C.F.R. § 1236.1(d)(1) ).
III. Excessive Bail Clause
Plaintiffs also argue that mandatory detention under § 1226(c) violates the Excessive Bail Clause of the Eighth Amendment. See U.S. Const. amend. VIII ("Excessive bail shall not be required ...."). The Excessive Bail Clause applies to civil immigration proceedings. See Browning-Ferris Indus. of Vt., Inc. v. Kelco Disposal, Inc., 492 U.S. 257, 263 n.3, 109 S.Ct. 2909, 106 L.Ed.2d 219 (1989) (stating that the Excessive Bail Clause is implicated by any "direct government restraint on personal liberty, be it in a criminal case or in a civil deportation proceeding"); Carlson v. Landon, 342 U.S. 524, 544-46, 72 S.Ct. 525, 96 L.Ed. 547 (1952) (assuming that the Excessive Bail Clause applied to deportation detention and ruling on the merits of detained aliens' excessive bail claims). It prohibits excessive bail in those cases where bail is granted. See Salerno, 481 U.S. at 752, 107 S.Ct. 2095 ; Carlson, 342 U.S. at 545, 72 S.Ct. 525. Thus, if a criminal alien's mandatory detention becomes unreasonably prolonged and an immigration court holds a bond hearing, the Eighth Amendment prohibits setting bond in an amount greater than necessary to *226secure the alien's future appearances. See Salerno, 481 U.S. at 754, 107 S.Ct. 2095.
Nonetheless, the Excessive Bail Clause does not guarantee bail in all cases. See id. at 752, 107 S.Ct. 2095 ; Carlson, 342 U.S. at 545, 72 S.Ct. 525 ; see also Bolante v. Keisler, 506 F.3d 618, 619 (7th Cir. 2007) ("[T]he Court has never held that persons detained in civil proceedings, such as deportation ... proceedings, are entitled to release on bail."). Congress may "defin[e] the classes of cases in which bail shall be allowed." Carlson, 342 U.S. at 545, 72 S.Ct. 525. Accordingly, mandatory detention for certain criminal aliens under § 1226(c) does not violate the Excessive Bail Clause. See Marogi v. Jenifer, 126 F. Supp. 2d 1056, 1061-62 (E.D. Mich. 2000) ; Avramenkov v. INS, 99 F. Supp. 2d 210, 218 (D. Conn. 2000). The Due Process Clause, not the Excessive Bail Clause, imposes limits on Congress's ability to detain aliens without an individualized hearing as part of the removal process. See Zadvydas, 533 U.S. at 690-96, 121 S.Ct. 2491 (explaining the due process concerns raised by potentially indefinite detention of an alien subject to a final order of removal); cf. Lopez-Valenzuela v. Arpaio, 770 F.3d 772, 792 n.16 (9th Cir. 2014) (explaining that "bail-denial schemes" in the criminal context are properly evaluated under the Due Process Clause, not the Excessive Bail Clause).
IV. Remedy
Plaintiffs ask the Court to issue a classwide injunction ordering the Government to provide all class members, who by definition have been detained at least six months, with either a bond hearing or a reasonableness hearing. Having concluded that due process requires a federal court to determine via an individual habeas petition that a criminal alien's mandatory detention under § 1226(c) has become unreasonable based on his particular circumstances before he is entitled to a bond hearing, the Court declines to issue either injunction Plaintiffs request. While certain class members whose mandatory detention has become unreasonable would be entitled to injunctions ordering the Government to provide them with a bond hearing, Federal Rule of Civil Procedure 23(b)(2), under which the class is certified, does not allow for individualized injunctions. See Wal-Mart Stores, Inc. v. Dukes, 564 U.S. 338, 360, 131 S.Ct. 2541, 180 L.Ed.2d 374 (2011) (" Rule 23(b)(2) applies only when a single injunction or declaratory judgment would provide relief to each member of the class."). The Court therefore need not address whether 8 U.S.C. § 1252(f)(1) prohibits a classwide permanent injunction ordering the Government to provide bond hearings for each class member.
The Government argues that § 1252(f)(1) deprives the Court of jurisdiction to issue even a classwide declaratory judgment concerning the rights of class members to a bond hearing. The Court already rejected this argument in the October 23, 2018 memorandum and order. See Reid, 2018 WL 5269992, at *6-7. Three justices in Preap subsequently stated that a district court has jurisdiction to entertain a request for declaratory relief despite § 1252(f)(1), 139 S. Ct. at 962 (opinion of Alito, J.), adding their voices to the three other justices who said the same in dissent in Jennings, 138 S. Ct. at 875 (Breyer, J., dissenting). Section 1252(f)(1) does not bar declaratory relief.
Finally, the Court may issue a classwide permanent injunction ordering the Government to follow the procedural rules mandated by due process at a bond hearing. These rules apply to any class member who is granted a bond hearing without regard to his individual circumstances.
*227Section 1252(f)(1), which strips courts of jurisdiction "to enjoin or restrain the operation of" certain provisions of the INA on a classwide basis, 8 U.S.C. § 1252(f)(1), does not bar this injunction because the INA is silent on the procedural rules for bond hearings, see Pensamiento, 315 F. Supp. 3d at 689. This injunction abrogates agency precedent imposing the burden of proof on the alien at a bond hearing, but it in no way enjoins or restrains the operation of the detention statute.
A court may issue a permanent injunction if "(1) plaintiffs prevail on the merits; (2) plaintiffs would suffer irreparable injury in the absence of injunctive relief; (3) the harm to plaintiffs would outweigh the harm the defendant would suffer from the imposition of an injunction; and (4) the public interest would not be adversely affected by an injunction." Healey v. Spencer, 765 F.3d 65, 74 (1st Cir. 2014) (quotation omitted). As discussed above, due process requires certain procedural protections at bond hearings. In the absence of an injunction, class members risk irreparable harm from the loss of their liberty. See Ferrara v. United States, 370 F. Supp. 2d 351, 360 (D. Mass. 2005) ("Obviously, the loss of liberty is a ... severe form of irreparable injury."). Since this injunction does not require bond hearings for each class member, it imposes minimal burden on the Government. Finally, the public interest supports requiring the Government to obey the Constitution in its administration of immigration detention. See Preminger v. Principi, 422 F.3d 815, 826 (9th Cir. 2005) ("[P]ublic interest concerns are implicated when a constitutional right has been violated, because all citizens have a stake in upholding the Constitution."). In opposing an injunction, the Government again emphasizes its concerns about criminal aliens' dangerousness and flight risk, but the procedural protections mandated by due process simply ensure that the Government detains only aliens who are in fact dangerous or flight risks. Plaintiffs have therefore met the four prerequisites for a permanent injunction ordering certain procedural protections at their bond hearings.
ORDER
For the foregoing reasons, Plaintiffs' motion for summary judgment is ALLOWED IN PART and DENIED IN PART (Docket No. 453), and the Government's motion for summary judgment is ALLOWED IN PART and DENIED IN PART (Docket No. 455).
The Court denies Plaintiffs' request for a permanent injunction ordering the Government to provide class members with bond or reasonableness hearings. The Court also denies Plaintiffs' request for a declaratory judgment insofar as they seek a declaration that due process requires an automatic bond hearing or reasonableness hearing for all criminal aliens detained under § 1226(c) for more than six months.
DECLARATORY JUDGMENT
The Court declares that mandatory detention without a bond hearing under 8 U.S.C. § 1226(c) violates due process when the detention becomes unreasonably prolonged in relation to its purpose in ensuring the removal of deportable criminal aliens. The most important factor in determining the reasonableness of a criminal alien's mandatory detention is the length of the detention. Mandatory detention without a bond hearing is likely to be unreasonable if it lasts for more than one year, excluding any delays due to the alien's dilatory tactics. A criminal alien subject to mandatory detention without a bond hearing under § 1226(c) must bring a habeas petition in federal court to challenge his detention as unreasonably prolonged. If the court agrees, the alien is entitled to a bond hearing before an immigration judge.
*228PERMANENT INJUNCTION
For any bond hearing held for a class member, the Court orders that the immigration court require the Government to prove that the alien is either dangerous by clear and convincing evidence or a risk of flight by a preponderance of the evidence. The immigration court may not impose excessive bail, must evaluate the alien's ability to pay in setting bond, and must consider alternative conditions of release such as GPS monitoring that reasonably assure the safety of the community and the alien's future appearances.
The Court orders that this declaratory judgment and permanent injunction be provided to all members of the class within thirty days and shall be provided to any new members of the class when their § 1226(c) detention exceeds six months.
SO ORDERED.
