1 2 3 4 5 6 7 UNITED STATES DISTRICT COURT 8 FOR THE EASTERN DISTRICT OF CALIFORNIA 9 10 MIGUEL ROMERO MENDOZA (A# No. 1:26-cv-01116 TLN SCR 092-107-308), 11 Petitioner, 12 FINDINGS & RECOMMENDATIONS v. 13 WARDEN, 14 Respondent. 15 16 Petitioner is a federal immigration detainee who filed this habeas corpus action pursuant 17 to 28 U.S.C. § 2241. The matter was referred to a United States Magistrate Judge pursuant to 28 18 U.S.C. § 636(b)(1)(B) and Local Rule 302. Because petitioner’s § 1226(c) detention is still 19 within the brief, constitutionally permissible period contemplated by the Supreme Court in 20 Demore v. Kim, 538 U.S. 510 (2003), the undersigned recommends the petition be denied. 21 I. Factual and Procedural History 22 Petitioner is a native of Mexico and currently detained at the Golden State Annex, within 23 this judicial district. ECF No. 1 at 2. Petitioner entered the United States without inspection on 24 October 1, 1981. ECF No. 7-1 at 6. He has several criminal convictions since that time, 25 including most recently a July 12, 2002, conviction in the U.S. District Court for the Western 26 District of Missouri, on three counts of distribution of a controlled substance, 21 U.S.C. § 27 841(a)(1), for which he was sentenced to 360 months in federal prison. Id. at 8; id. at 16-27 28 (“Rap Sheet”). 1 On December 9, 2025, after conducting a telephone interview with petitioner during his 2 incarceration at USP Atwater, Immigration and Customs Enforcement (ICE) officials determined 3 petitioner was removable under INA § 237(a)(2)(A)(iii) [8 U.S.C. § 1227(a)(2)(A)(iii)] based on 4 his federal criminal convictions that qualified as aggravated felonies as defined in INA § 5 101(a)(43)(B) and (U). ECF No. 7-1 at 6. On December 26, 2025, petitioner was released from 6 federal prison to ICE custody. ECF No. 7-2 at 1; ECF No. 1 at 19. ICE instituted removal 7 proceedings against petitioner. 8 Petitioner filed the instant petition on February 9, 2026, challenging his prolonged 9 detention under the Due Process Clause of the Fifth Amendment. ECF No. 1. Petitioner alleges 10 he is being detained without having committed a new crime. Id. at 19. The facility is 11 overcrowded, which exacerbates his chronic urticaria and weakened immune system. Id. at 20. 12 Petitioner regrets his crimes and wishes to fight his immigration case out of custody and with 13 appropriate supervision so that he can see his family, including his six grandchildren whom he 14 has yet to meet. Id. at 21-23. By way of relief, petitioner requests his release or, in the 15 alternative, a bond hearing before an immigration judge (“IJ”) in which the government must 16 prove, by clear and convincing evidence, that he poses a danger or flight risk. Id. at 17. 17 Respondent asserts petitioner is subject to mandatory detention under 8 U.S.C. § 18 1226(c)(1)(B) on account of his 2002 conviction. ECF No. 7 at 2-3. Respondent first emphasizes 19 that the Supreme Court upheld mandatory detention under Section 1226(c) as facially 20 constitutional in Demore, 538 U.S. 510. Id. at 3-4. Next, respondent argues that petitioner’s 21 detention is constitutional under the Mathews v. Eldridge, 424 U.S. 319 (1976) framework and 22 any of the various other procedural due process tests applied by district courts within this circuit. 23 Id. at 5-6. Respondent explains that petitioner’s detention has a “definite” termination point when 24 his removal proceedings conclude and that the government has a strong interest in detaining 25 individuals like petitioner who have serious prior criminal convictions. Id. 26 II. Applicable Detention Statute 27 The statutory framework governing immigration detention is complex. “Where a 28 [noncitizen] falls within this statutory scheme can affect whether his detention is mandatory or 1 discretionary, as well as the kind of review process available to him if he wishes to contest the 2 necessity of his detention.” Prieto-Romero v. Clark, 534 F.3d 1053, 1057 (9th Cir. 2008). 3 Respondent argues that petitioner is subject to mandatory detention per § 1226(c)(1)(B) 4 based on his 2002 conviction under 8 U.S.C. § 841(a). ECF No. 7 at 2-3. Section 1226(c)(1)(B) 5 states that “[t]he Attorney General shall take into custody” any noncitizen who is deportable by 6 reason of having committed any offense covered in, inter alia, 8 U.S.C. § 1227(a)(2)(A)(iii). ICE 7 officials charged petitioner as removable under § 1227(a)(2)(A)(iii), which applies to noncitizens 8 “convicted of an aggravated felony[.]” Respondent identifies petitioner’s 2002 conviction as an 9 “aggravated felony” per 8 U.S.C. § 1101(a)(43)(B), which defines the term to include “illicit 10 trafficking in a controlled substance.” See, e.g., Sandhu v. United States, No. 2:05-cr-0449 KJM, 11 2020 WL 417542, at *5 (E.D. Cal. Jan. 27, 2020) (finding that the deportation consequences of a 12 21 U.S.C. § 841(a) conviction were “made express” in 8 U.S.C. §§ 1101(a)(43)(B) and 13 1227(a)(2)(A)(iii)). Accordingly, the undersigned finds petitioner’s detention is governed by § 14 1226(c)(1)(B). 15 III. Legal Standard 16 The Due Process Clause protects persons in the United States from being deprived of life, 17 liberty, or property without due process of law. U.S. Const. amend. V. The Supreme Court has 18 concluded that “the Due Process Clause applies to all ‘persons’ within the United States, 19 including [non-citizens], whether their presence here is lawful, unlawful, temporary, or 20 permanent.” Zadvydas v. Davis, 533 U.S. 678, 693 (2001). Courts examine procedural due 21 process claims in two steps: the first step is determining whether there exists a protected liberty 22 interest under the Due Process Clause. The second step examines the procedures necessary to 23 ensure any deprivation of that protected liberty interest accords with the Constitution. See 24 Kentucky Dep’t of Corrections v. Thompson, 490 U.S. 454, 460 (1989); Morrissey v. Brewer, 25 408 U.S. 471, 481 (1972) (“Once it is determined that due process applies, the question remains 26 what process is due.”). 27 As respondent notes, “there is a general dearth of guidance on the appropriate test or 28 standard to apply to an as-applied challenge to prolonged detention claims.” ECF No. 7 at 5.

Clark, 534 F.3d 1053, 1057 (9th Cir. 2008). 3 Respondent argues that petitioner is subject to mandatory detention per § 1226(c)(1)(B) 4 based on his 2002 conviction under 8 U.S.C. § 841(a). ECF No. 7 at 2-3. Section 1226(c)(1)(B) 5 states that “[t]he Attorney General shall take into custody” any noncitizen who is deportable by 6 reason of having committed any offense covered in, inter alia, 8 U.S.C. § 1227(a)(2)(A)(iii). ICE 7 officials charged petitioner as removable under § 1227(a)(2)(A)(iii), which applies to noncitizens 8 “convicted of an aggravated felony[.]” Respondent identifies petitioner’s 2002 conviction as an 9 “aggravated felony” per 8 U.S.C. § 1101(a)(43)(B), which defines the term to include “illicit 10 trafficking in a controlled substance.” See, e.g., Sandhu v.

Accordingly, the undersigned finds petitioner’s detention is governed by § 14 1226(c)(1)(B). 15 III. Legal Standard 16 The Due Process Clause protects persons in the United States from being deprived of life, 17 liberty, or property without due process of law. U.S. Const. amend. V. The Supreme Court has 18 concluded that “the Due Process Clause applies to all ‘persons’ within the United States, 19 including [non-citizens], whether their presence here is lawful, unlawful, temporary, or 20 permanent.” Zadvydas v. Davis, 533 U.S. 678, 693 (2001). Courts examine procedural due 21 process claims in two steps: the first step is determining whether there exists a protected liberty 22 interest under the Due Process Clause. The second step examines the procedures necessary to 23 ensure any deprivation of that protected liberty interest accords with the Constitution. See 24 Kentucky Dep’t of Corrections v. Thompson, 490 U.S. 454, 460 (1989); Morrissey v. Brewer, 25 408 U.S. 471, 481 (1972) (“Once it is determined that due process applies, the question remains 26 what process is due.”). 27 As respondent notes, “there is a general dearth of guidance on the appropriate test or 28 standard to apply to an as-applied challenge to prolonged detention claims.” ECF No. 7 at 5. 1 While observing “district courts throughout this circuit have ordered immigration courts to 2 conduct bond hearings for noncitizens held for prolonged periods under § 1226(c),” the Ninth 3 Circuit has expressly declined to address “[w]hether due process requires a bond hearing” in such 4 situations. Martinez v. Clark, 36 F.4th 1219, 1223 (9th Cir. 2022), cert. granted, judgment 5 vacated, 144 S. Ct. 1339 (2024). But it has previously expressed “grave doubts that any statute 6 that allows for arbitrary prolonged detention without any process is constitutional or that those 7 who founded our democracy precisely to protect against the government’s arbitrary deprivation of 8 liberty would have thought so.” Rodriguez v. Marin, 909 F.3d 252, 256 (9th Cir. 2018). 9 The undersigned finds Mathews provides the appropriate test and recognizes the assigned 10 district judge has also applied it to such challenges. See, e.g., Jose G. M. L. v. Warden of the 11 Golden State Annex Det. Facility, No. 1:26-cv-0047 TLN EFB, 2026 WL 472987, at *4 (E.D. 12 Cal. Feb. 19, 2026); Gopal B. v. Albarran, No. 1:26-cv-1083 TLN CKD, 2026 WL 504736, at *4 13 (E.D. Cal. Feb. 24, 2026). The undersigned is particularly persuaded by the Second Circuit’s 14 reasoning in Black v. Decker, 103 F.4th 133, 149 (2d Cir. 2024), that the Mathews test is flexible 15 enough to account for the additional factors identified by the Third Circuit in German Santos v. 16 Warden Pike Cnty. Corr. Facility, 965 F.3d 203 (3d Cir. 2020),1 and other district courts when 17 deciding whether § 1226(c) detention has become unreasonably prolonged. Under Mathews, the 18 court considers three factors: (1) the private interest affected; (2) the risk of an erroneous 19 deprivation of that interest; and (3) the government’s interest involved including any fiscal or 20 administrative burden that additional procedures would include. Mathews, 424 U.S. at 335. 21 IV. Discussion 22 A. As-Applied Framework 23 The undersigned construes the petition as raising an as-applied, procedural due process 24 challenge to the constitutionality of petitioner’s detention under § 1226(c)(1)(B). See ECF No. 1 25
26 1 In German Santos, the Third Circuit declined to adopt a presumption of reasonableness or unreasonableness of any duration and instead evaluated duration along with three other factors: 27 (1) whether the detention is likely to continue; (2) the reasons for the delay, such as a detainee's request for continuances; and (3) whether the noncitizen’s conditions of confinement are 28 “meaningfully different[ ] ” from criminal punishment. 965 F.3d at 211. 1 at 9-13. Although the Supreme Court upheld the facial constitutionality of mandatory detention 2 under § 1226(c) in Demore, it did so with the understanding that such detention is relatively 3 “brief” and “limited,” and “lasts roughly a month and a half in the vast majority of cases” and 4 “about five months in the minority of cases in which the alien chooses to appeal.” Demore, 538 5 U.S. at 513, 529 n.12, 530. Later, in Nielsen v. Preap, 586 U.S. 392 (2019), the Supreme Court 6 expressly recognized the right to bring as-applied challenges to the mandatory detention under § 7 1226(c): “Our decision today on the meaning of that statutory provision [8 U.S.C. § 1226(c)] does 8 not foreclose as-applied challenges—that is, constitutional challenges to applications of the 9 statute as we have now read it.” Preap, 586 U.S. at 420. Since Demore and Preap, “[c]ourts in 10 the Ninth Circuit routinely review as-applied constitutional challenges to § 1226(c) detention.” 11 Jose G. M. L., 2026 WL 472987, at *3 (collecting cases). 12 But before proceeding to the analysis, the undersigned first rejects respondent’s primary 13 argument that petitioner’s as-applied challenge fails because his detention is not “indefinite.” 14 ECF No. 7 at 5-6. The Ninth Circuit has recognized that “‘indefinite and potentially permanent’ 15 civil detention . . . clearly pose[s] serious substantive due process concerns.” Prieto-Romero v. 16 Clark, 534 F.3d 1053, 1064 (9th Cir. 2008) (citing Zadvydas, 533 U.S. at 696) (emphasis added). 17 The question presented here is not whether petitioner’s detention appears to be “indefinite,” but 18 whether his mandatory detention of approximately three months without a fair detention hearing 19 violates procedural due process. As explained above, courts entertain such as-applied, procedural 20 due process claims despite the Supreme Court’s finding in Demore, 538 U.S. at 529, that § 1226 21 detention has a “definite termination point.” See Black, 103 F.4th at 149 (“Demore upheld the 22 government’s authority under section 1226(c) to detain noncitizens without an initial bond 23 hearing for the brief period necessary for their removal proceedings. It said nothing about whether 24 due process may eventually require a hearing.”) (internal quotations and citations omitted) 25 (emphasis in original). 26 In sum, while prolonged and indefinite detention is necessary to show entitlement to 27 outright release under the Zadvydas framework, prolonged detention—even if not indefinite— 28 may be sufficient to require a detention hearing. See Lopez v. Garland, 631 F. Supp. 3d 870, 877 1 (E.D. Cal. 2022) (“[E]ssentially all district courts that have considered the issue agree that 2 prolonged mandatory detention pending removal proceedings, without a bond hearing, will—at 3 some point—violate the right to due process.”) (quotation omitted). With this framework in 4 mind, the undersigned turns to the procedural due process analysis. 5 B. Procedural Due Process Analysis 6 Turning to the first step, the facts of this case present several barriers to finding of a 7 protected liberty interest. Petitioner undoubtedly has a liberty interest in “‘freedom from 8 prolonged detention’ [that] is ‘unquestionably substantial.’” Rodriguez Diaz v. Garland, 53 F.4th 9 1189, 1207 (9th Cir. 2022) (quoting Singh v. Holder, 638 F.3d 1196, 1208 (9th Cir. 2011)). 10 However, petitioner has been detained for just over three months. In Demore, the Supreme Court 11 held the petitioner’s six-month detention under § 1226(c) was “constitutionally permissible” 12 despite being “somewhat longer than average.” 538 U.S. at 530-531. Further, although the Ninth 13 Circuit has not addressed when mandatory detention under § 1226(c) becomes prolonged, it has 14 similarly referred to detentions longer than six months as prolonged “in the context of detentions 15 for which no individualized bond hearings had taken place at all because the statutes on their 16 faces did not allow for them.” Rodriguez Diaz, 53 F.4th at 1207 (citations omitted); see also 17 Zadvydas, 533 U.S. at 701 (recognizing a “6–month period” of presumptively reasonable post- 18 removal-period detention). Therefore, given that the duration of petitioner’s detention is still 19 within the range contemplated in Demore, the undersigned finds that it does not yet implicate his 20 protected interest against prolonged detention. 21 Moreover, this is not a case where petitioner accrued a liberty interest after being 22 previously released by DHS or an IJ. Rather, he was released from federal prison and 23 immediately arrested by ICE. As a fellow judge of this judicial district has explained, noncitizens 24 do not acquire protected liberty interests in their release under such circumstances:
25 “[T]he liberty interests of [an individual] who is re-arrested differ from the liberty interests of a detained person.” Guillermo M.R. v. Kaiser, No. 25-cv-05436-RFL, 26 2025 WL 1810076, at *1 (N.D. Cal. June 30, 2025). In the former situation, where ICE detains an individual upon their release from a correctional facility, 27 without any substantial intervening period of release, that individual has no opportunity “to form the [ ] enduring attachments of normal life.” Morrissey v. 28 Brewer, 408 U.S. 471, 482 (1972). In contrast, a person who has been released 1 from physical restraint gains a “liberty [interest that] is valuable and must be seen as within the protection of the” Due Process Clause. Id. 2 3 Carballo v. Andrews, No. 1:25-cv-0978 KES EPG (HC), 2025 WL 2381464, at *4 (E.D. Cal. 4 Aug. 15, 2025). Thus, petitioner cannot claim a protected liberty interest based on continued 5 freedom from any previous release from custody. 6 Petitioner still retains a general liberty interest in freedom from detention. “‘[F]reedom 7 from imprisonment . . . lies at the heart of the liberty [the Due Process Clause] protects.’” 8 Zadvydas, 533 U.S. at 690. But applying the Mathews factors to that private interest, the 9 relatively short duration of petitioner’s § 1226(c) detention significantly diminishes its strength. 10 “[T]he longer mandatory detention continues under 8 U.S.C. § 1226(c) beyond the ‘brief’ period 11 authorized in Demore, the harder it becomes to justify without conducting an individualized bond 12 hearing.” Sarr v. Scott, 765 F. Supp. 3d 1091, 1098 (W.D. Wash. 2025); cf. Black, 103 F.4th at 13 151 (finding first Mathews factor “weighs heavily in favor” of petitioners where they were 14 detained for “far longer” than the petitioner in Demore). 15 Further, the risk of erroneous deprivation is currently low where the duration of 16 petitioner’s detention does not exceed that of the petitioner in Demore, and petitioner presumably 17 had an opportunity to challenge his inclusion in a mandatory detention category pursuant to 18 Matter of Joseph, 22 I. & N. Dec. 799 (BIA 1999)). However, the risk of erroneous deprivation 19 will increase over time as his detention becomes prolonged due to the “almost nonexistent 20 procedural protections in place for section 1226(c) detainees.” Black, 103 F.4th at 152. 21 Finally, precedent dictates that “[t]he government has an obvious interest in ‘protecting 22 the public from dangerous criminal aliens.’” Rodriguez Diaz, 53 F.4th at 1208 (quoting Demore, 23 538 U.S. at 515). Indeed, in Demore, the Supreme Court expressly upheld the brief detention of 24 criminal noncitizens without an individualized determination of dangerousness. See 510 U.S. at 25 528. While this factor currently favors the government, it too will tilt toward petitioner as his 26 detention without an individualized determination of danger or flight risk becomes prolonged. 27 See Black, 103 F.4th at 153–54 (“The additional procedural safeguards we would allow here 28 under Mathews do nothing to undercut those interests. At any ordered bond hearing, the IJ would 1 || assess on an individualized basis whether the noncitizen presents a flight risk or a danger to the 2 || community, as IJs routinely do for other noncitizen detainees.”); Jimenez v. Wolf, No. 19-cv- 3 || 7996 NC, 2020 WL 510347, at *3 (N.D. Cal. Jan. 30, 2020) (“Providing a bond hearing would 4 || not undercut the government’s asserted interest in effecting removal. After all, the purpose of a 5 || bond hearing is to inquire whether the alien represents a flight risk or danger to the community.”) 6 || (citing In re Guerra, 24 I.&N. Dec. 37 (B.I-A. 2006)). 7 On balance, the Mathews factors weigh against ordering a bond hearing at the current, 8 | three-month juncture of petitioner’s immigration detention. Accordingly, the undersigned 9 || recommends that the petition be denied. However, these findings and recommendations do not 10 | preclude petitioner from seeking a bond hearing through a subsequent § 2241 petition at a later 11 | point in time should his detention become prolonged. 12 CONCLUSION 13 Accordingly, IT IS HEREBY RECOMMENDED that petitioner’s (A# 092-107-308) 14 | application for a writ of habeas corpus be DENIED without prejudice. 15 These findings and recommendations are submitted to the United States District Judge 16 || assigned to the case, pursuant to the provisions of 28 U.S.C. § 636(b)(1). Within seven days after 17 || being served with these findings and recommendations, any party may file written objections with 18 | the court and serve a copy on all parties. The undersigned finds that a shortened objection period 19 | is warranted in this case given the nature of the relief at issue as well as the fact that the parties 20 | have had sufficient time to submit all of their arguments in written briefs. See United States v. 21 || Barney, 568 F.2d 134, 136 (9th Cir. 1978) (per curiam) (stating that 28 U.S.C. § 636(b)(1) sets 22 || the maximum objection period and not the minimum); see also Local Rule 304(b). The parties 23 || are advised that failure to file objections within the specified time may waive the right to appeal 24 || the District Court’s order. Martinez v. YIst, 951 F.2d 1153 (9th Cir. 1991). 25 || DATED: April 2, 2026
