DICSON OBEL AGUILAR- Case No.: 26cv3758-LL-AHG MAZARIEGOS, ORDER GRANTING AMENDED Petitioner, PETITION FOR WRIT OF HABEAS v. CORPUS

MARKWAYNE MULLIN, Secretary of [ECF No. 5] the Department of Homeland Security, et al., Respondents. Before the Court is Petitioner Dicson Obel Aguilar-Mazariegos’s Amended Petition for a Writ of Habeas Corpus pursuant to 28 U.S.C. § 2241. ECF No. 5 (“Pet.”). Respondents filed a Response [ECF No. 6], and Petitioner filed a Traverse [ECF No. 7]. For the reasons set forth below, the Court GRANTS Petitioner’s Petition for Writ of Habeas Corpus. Petitioner is a citizen of Honduras who entered the United States in 2018 when he was 16 years old. Pet. at 2; see also Exh. A to Pet., Declaration of Dicson Obel Aguilar- Mazariegos (“Decl.”). On November 9, 2018, Petitioner went to a port of entry, along with his father and brother, and asked for asylum. Pet. at 2; Decl. ¶ 2. Petitioner was held in custody for eight days before being released on conditional parole. Pet. at 2; Decl. ¶ 2. After his release, Petitioner went to Miami, Florida with his family and applied for asylum. Pet. at 2; Decl. ¶ 3. He has since attended all his check-in appointments and complied with the conditions of his release. Pet. at 2, 4; Decl. ¶ 3. Since his release, Petitioner has obtained a work permit and Social Security number. Pet. at 2, 4; Decl. ¶ 3. On May 4, 2026, Immigration and Customs Enforcement (“ICE”) detained Petitioner without any notice or opportunity to be heard. Pet. at 2; Decl. ¶ 4. Petitioner has no criminal record. Pet. at 2; Decl. ¶ 3. On July 7, 2026, Petitioner filed the instant Amended Petition, claiming that the revocation of his parole without proper notice, reasoning, and a pre-deprivation hearing violates the Administrative Procedures Act and the Fifth Amendment’s Due Process Clause. Pet. at 3–7. Respondents argue in the Response that they “concede Petitioner was previously released from immigration custody on parole, however, Respondents have insufficient information regarding whether [his] parole terminated or expired to provide to the Court.” ECF No. 6 at 2. Respondents further argue that “Petitioner’s habeas petition is ambiguous as to the parole authority he was released under, citing both 8 U.S.C. § 1182(d)(5) and 8 C.F.R. § 212.5 (e )(2)(i).” Id. Respondents argue that it is their position that Petitioner is subject to mandatory detention under § 1225(b)(2), but acknowledge that Courts in this District have repeatedly reached the opposite conclusion under the same and/or similar facts. Id. Respondents also state in their Response that “the government does not oppose the petition and defers to the Court on the appropriate relief.” Id. at 3. A federal prisoner challenging the execution of his or her sentence, rather than the legality of the sentence itself, may file a petition for writ of habeas corpus in the district of his or her confinement pursuant to 28 U.S.C. § 2241. See 28 U.S.C. § 2241(a). The sole judicial body able to review challenges to final orders of deportation, exclusion, or removal is the court of appeals. See 8 U.S.C. § 1252; see also Alvarez-Barajas v. Gonzales, 418 F.3d 1050, 1052 (9th Cir. 2005) (citing REAL ID Act, Pub. L. No. 109-13, 119 Stat. 231, § 106(a)). However, for claims challenging ancillary or collateral issues arising independently from the removal process – for example, a claim of indefinite detention – federal habeas corpus jurisdiction remains in the district court. See Nadarajah v. Gonzales, 443 F.3d 1069, 1076 (9th Cir. 2006), abrogated on other grounds by Jennings v. Rodriguez, 583 U.S. 281 (2018); Alvarez v. Sessions, 338 F. Supp. 3d 1042, 1048–49 (N.D. Cal. 2018). Petitioner argues that the summary revocation of his parole without justification or consideration of his individualized circumstances violates the Due Process Clause. Pet. at 6–7. Specifically, Petitioner argues that he was “entitled to notice of the reasons for revocation of his parole and a hearing before an immigration judge to determine whether detention is warranted before ICE revoked his parole.” Id. at 6 (internal quotation and citation omitted). The Court agrees. The Fifth Amendment guarantees that “[n]o person shall be . . . deprived of life, liberty, or property, without due process of law.” U.S. Const. amend. V. “[T]he Due Process Clause applies to all ‘persons’ within the United States, including aliens, whether their presence here is lawful, unlawful, temporary, or permanent.” Zadvydas v. Davis, 533 U.S. 678, 693 (2001). “It is well established that the Fifth Amendment entitles aliens to due process of law in deportation proceedings.” Reno v. Flores, 507 U.S. 292, 306 (1993). The Due Process Clause generally “requires some kind of a hearing before the State deprives a person of liberty or property.” Zinermon v. Burch, 494 U.S. 113, 127 (1990). “Even individuals who face significant constraints on their liberty or over whose liberty the government wields significant discretion retain a protected interest in their liberty.” Pinchi v. Noem, 792 F. Supp. 3d 1025, 1032 (N.D. Cal. 2025) (citations omitted). Although the initial decision to detain or release an individual may be within the government’s discretion, “the government’s decision to release an individual from custody creates ‘an implicit promise,’ upon which that individual may rely, that their liberty ‘will be revoked only if [they] fail[] to live up to the . . . conditions [of release].’” Id. (quoting Morrissey v. Brewer, 408 U.S. 471, 482 (1972)). “Thus, even when ICE has the initial discretion to detain or release a noncitizen pending removal proceedings, after that individual is released from custody she has a protected liberty interest in remaining out of custody.” Pinchi, 792 F. Supp. 3d at 1032 (citing Romero v. Kaiser, No. 22-cv-02508-TSH, 2022 WL 1443250, at *2 (N.D. Cal. May 6, 2022)). Petitioner entered the United States in 2018. Pet. at 2. Petitioner is not a newly arrived noncitizen seeking admission at the border. Id. Petitioner is not merely an “applicant for admission” at the border with minimal due process rights; he was previously released by the Government from custody in 2018 and has a protected liberty interest in remaining out of custody. See, e.g., Pinchi, 792 F. Supp. 3d at 1034 (“[Petitioner’s] release from ICE custody after her initial apprehension reflected a determination by the government that she was neither a flight risk nor a danger to the community, and [Petitioner] has a strong interest in remaining at liberty unless she no longer meets those criteria.”); Noori v. LaRose, 807 F. Supp. 3d 1146, 1164 (S.D. Cal. 2025) (“Petitioner is not an ‘arriving’ noncitizen but one that has [been] present in our country for over a year. This substantial amount of time indicates he is afforded the Fifth Amendment’s guaranteed due process before removal.”); Alvarenga Matute v. Wofford, 807 F. Supp. 3d 1120, 1128– 29 (E.D. Cal. 2025) (finding petitioner had a protected liberty inte
