Opinion

MARIO ERNESTO RIVERA AGUILAR Case No. 1:26-cv-03028-DAD-JDP (A-Number: 221-468-402), Petitioner, FINDINGS AND RECOMMENDATIONS v. TONYA ANDREWS, et al., Respondents. Petitioner Mario Ernesto Rivera Aguilar entered the United States in 1995. ECF No. 1-1 at 4. He was detained by ICE in December 2025 following a traffic stop. ECF No. 1-1 at 8. Since his detention, petitioner has not received a bond hearing. The immigration court determined that he is subject to mandatory detention under 8 U.S.C. § 1225 and that it lacks jurisdiction to conduct a bond hearing. ECF No. 1-1 at 23. Petitioner seeks a writ of habeas corpus under 28 U.S.C. § 2241, and argues that his detention is not mandatory. For the following reasons, I recommend that the petition be granted and that petitioner be immediately released. Background Petitioner is a Mexican citizen who entered the United States without inspection in or about 1995.1 ECF No. 1-1 at 8. There is no indication in the record that petitioner has applied for 1 It appears that petitioner voluntarily returned to Mexico in 2001 and re-entered the United States without inspection sometime thereafter. See ECF No. 1-1 at 8; ECF No. 9 at 1. asylum. In 2005, petitioner was convicted for possession of a controlled substance under Utah law; this conviction has since been vacated. See ECF No. 9-1 at 13-14; ECF No. 10-1 at 11-13. In 2008, petitioner was convicted of driving under the influence and hit and run, both misdemeanors. ECF No. 9-1 at 15-16. In 2023, petitioner was convicted of disorderly conduct, a class C misdemeanor. Id. at 16-17, 37. On December 6, 2025, petitioner was detained by immigration officers in Utah pursuant to a traffic stop. ECF No. 1-1 at 8. The Department of Homeland Security issued petitioner a notice to appear alleging that he is a noncitizen present in the United States without having been inspected and admitted or paroled, and that he lacks valid entry documents. Id. at 21. Petitioner requested a bond hearing from the immigration court. ECF No. 1 at 8. On January 22, 2026, the immigration court denied that request under Matter of Yajure Hurtado, 29 I. & N. Dec. 216 (BIA 2025), which interpreted that mandatory detention provision of 8 U.S.C. § 1225 to apply to those, like petitioner, arrested by immigration authorities in the interior of the United States. See ECF No. 1-1 at 23. Petitioner is currently detained at the Golden State Annex detention facility. Id. at 2. Legal Standard A federal court may grant habeas relief when a petitioner shows that his custody violates federal law. 28 U.S.C. §§ 2241(a), (c)(3), 2254(a); Williams v. Taylor, 529 U.S. 362, 374-75 (2000). “[T]he essence of habeas corpus is an attack by a person in custody upon the legality of that custody, and . . . the traditional function of the writ is to secure release from illegal custody.” Preiser v. Rodriguez, 411 U.S. 475, 484 (1973). A writ of habeas corpus may be granted to a petitioner who demonstrates that he is in custody in violation of the Constitution or federal law. 28 U.S.C. § 2241(c)(3). Historically, “the writ of habeas corpus has served as a means of reviewing the legality of Executive detention, and it is in that context that its protections have been strongest.” I.N.S. v. St. Cyr, 533 U.S. 289, 301 (2001). A district court’s habeas jurisdiction includes challenges to immigration detention. Zadvydas v. Davis, 533 U.S. 678, 687 (2001). Analysis Petitioner argues that his detention is governed by 8 U.S.C. § 1226(a) and that he is not subject to mandatory detention under either 8 U.S.C. §§ 1226(c) or 1225(b)(2). ECF No. 13 at 3- 5. Respondents counter that petitioner’s detention is mandatory under 8 U.S.C. § 1226(c) based on petitioner’s prior controlled substance offense. ECF No. 9. Petitioner responds that his prior controlled substance conviction was vacated by state court as having resulted from ineffective assistance of counsel and as such cannot be relied on by respondents. ECF No. 10 at 2. Petitioner further points out that the immigration court refused a bond hearing under section 1225, not section 1226(c). ECF Nos. 1 at 7, 14, 10 at 7. I address sections 1226(c) and 1225(b)(2) in turn. I. 1226(c) Under section 1226(c), the attorney general “shall take into custody” any noncitizen “who is inadmissible by reason of having committed any offense covered in section 1182(a)(2) of this title.” 8 U.S.C. § 1226(c)(1)(A). Section 1182 (a)(2) includes any noncitizen “convicted of … a violation of . . . any law or regulation of a State . . . relating to a controlled substance (as defined in section 802 of title 21).” 8 U.S.C. § 1182(a)(2)(A)(i)(II). A conviction vacated for a substantive or procedural constitutional defect is no longer a “conviction” for immigration purposes. Cardoso-Tlaseca v. Gonzales, 460 F.3d 1102, 1107 (9th Cir. 2006); Nath v. Gonzales, 467 F.3d 1185, 1189 (9th Cir. 2006). The Court of Appeals has held that “the reasoning because the petitioner’s motive [for vacatur] is not the crucial inquiry” in determining whether a conviction was vacated for a substantive or procedural constitutional defect. Reyes-Torres v. Holder, 645 F.3d 1073, 1077 (9th Cir. 2011). “Instead, the inquiry must focus on the state court’s rationale for vacating the conviction, and the burden is on the government to prove that it was vacated solely for rehabilitative reasons or reasons related to his immigration status.” Id. (cleaned up). Here, respondents argue that petitioner is subject to mandatory detention under section 1226(c) because he suffered a Utah controlled substance offense conviction in 2005. ECF No. 9- 1 at 22. Petitioner responds by filing proof that, on March 18, 2026, the Utah Third District Court vacated that conviction as follows:

The Court specifically finds and orders that this vacatur is granted solely because the conviction was obtained in violation of [petitioner’s] constitutional right to effective assistance of counsel, i.e., a defect in the validity of the plea proceedings. This relief is not granted for rehabilitative purposes, equitable considerations, or to alleviate collateral consequences independent of the constitutional error.
