Suri: A Detention Challenge Could Proceed When the Custodian Was Unknown

When a loved one is moved between immigration facilities, a missing location can mean more than a missed call. It can leave a lawyer trying to seek release without knowing which official to name or which federal court can hear the case. Badar Khan Suri’s appeal turned partly on that urgent problem: His lawyer filed while his location and immediate custodian were still unknown to counsel.

In Suri v. Trump, No. 25-1560 (4th Cir. July 23, 2026), the Fourth Circuit allowed his detention challenge to proceed in Virginia. It upheld the district court’s authority to hear the petition, its refusal to transfer the case and its order protecting the pending case against removal. The majority connected those conclusions to the actual transfer record and to Suri’s challenge to custody. Judge Wilkinson dissented over Congress’s rules for reviewing removal-related claims.

The filing fell between arrival and booking

Suri was a Georgetown University research scholar living with his family in Virginia. Officers arrested him outside his home in Rosslyn on March 17, 2025. His habeas petition alleged that the government had detained him in retaliation for speech and had violated his First and Fifth Amendment rights. Those were his allegations for the court to consider, rather than findings establishing his constitutional claims.

The next day’s sequence mattered. After being held in Virginia, he was flown to Louisiana, arriving at 5:03 p.m. His lawyer filed the petition in the Eastern District of Virginia at 5:59 p.m. He was booked into the Alexandria facility at 6:42 p.m.—43 minutes after filing. All three times in the Suri opinion’s chronology are Eastern Daylight Time. His arrival in Louisiana and his booking into a named facility were different events.

Counsel had filed an appearance that afternoon and repeatedly checked the online detainee locator, which returned no information. The last location reported to Suri’s wife was in Virginia. His charging document pointed to a future hearing in Texas, and he would not actually reach Texas until three days after the petition was filed. The locator displayed his whereabouts the following day. A later-confirmed location therefore did not describe what his lawyer could know at the moment of filing.

The ordinary rule starts with the person holding you

A habeas petition asks a court to examine the legality of custody. For a challenge to present physical confinement, the ordinary starting point is the facility’s warden or administrator and the federal district containing that facility. The statutes give that inquiry a practical focus: 28 U.S.C. section 2242 calls for identifying the custodian and the authority for detention, if known, and section 2243 directs the writ or order to show cause to the person having custody.

The Supreme Court applied the immediate-custodian and district-of-confinement rules in Rumsfeld v. Padilla, 542 U.S. 426, 434–435, 442–447 (2004). The Fourth Circuit used that framework in Suri’s case. For a California example involving a known facility, our analysis of Doe v. Garland explains why naming supervisory officials and filing outside the detention district undid a grant of habeas relief.

The difficulty in Suri was identifying that immediate custodian while a rapid transfer was underway. The majority kept this question separate from subject-matter jurisdiction—the court’s authority to decide the kind of legal claim presented. Choosing the proper respondent and filing district was one inquiry; deciding whether immigration statutes required his claims to follow a different review process was another.

Two separate exceptions supported the Virginia filing

The first was an unknown-custodian exception. The majority drew on the Supreme Court’s recognition that ordinary naming rules may be impossible to follow when a prisoner’s whereabouts are unknown. In Suri’s application of that exception, counsel’s knowledge mattered: His lawyer could identify neither the detention location nor the immediate custodian when filing. Even the government could not identify his immediate custodian during the interval between arrival and booking. In those circumstances, naming the ultimate custodian allowed the case to proceed.

The second was an independent ground involving the government’s conduct. In his concurrence in Rumsfeld v. Padilla, 542 U.S. at 454, Justice Kennedy described an exception when the government moves a prisoner to make filing difficult or withholds the location and custodian’s identity. The Fourth Circuit applied that reasoning to the district court’s findings of secrecy and forum manipulation. The government had not challenged those factual findings on appeal.

The Suri majority’s examination of the transfers considered the quick moves, information withheld from counsel and the government’s explanations for detention space and destinations. The two grounds did different work: One addressed counsel’s inability to identify the custodian; the other addressed the government’s handling of the transfers. A family trying to reconstruct a similar emergency should preserve both what was learned and when it became available, along with the actual requests and responses.

A later Texas destination did not decide transfer

The government also asked the Fourth Circuit to move the case. Its Louisiana argument had not been presented to the district court and was forfeited on appeal. Texas presented another problem: Suri was not there when counsel filed. A Texas address in a charging document could not substitute for his actual custody history.

In Suri’s separate transfer analysis, the court also considered the Virginia connections, including his home, family and lawyers, and the absence of identified prejudice to the government from litigating there. It upheld the district court’s refusal to transfer. That conclusion followed the court’s determination that the original filing was proper under the exceptions it had applied.

The sequence matters when reading the court’s discussion of Ex parte Endo. That decision concerned a court retaining jurisdiction it had already acquired after the government moved the detained person. In Suri, the unknown-custodian exception first supplied the basis for a proper filing; later moves then raised the continuing-jurisdiction question. Our guide to detention transfers and habeas filing in California explains why a move before filing and a move afterward require separate attention.

The court examined custody and removal review separately

The harder disagreement concerned three provisions of 8 U.S.C. section 1252. Subsection (g) addresses claims arising from decisions to commence proceedings, adjudicate cases or execute removal orders. Subsection (b)(9) gathers removal-related legal and factual questions into review of a final removal order. Subsection (a)(5) makes a petition for review in the appropriate court of appeals the exclusive route for judicial review of a removal order, subject to its stated exception.

The majority treated Suri’s custody challenge as distinct from those removal decisions. His amended petition sought relief concerning apprehension, detention and transfer. That amendment mattered: The original petition had also asked for protection against targeting him for removal. The Suri opinion identifies the changed request rather than treating every version of the pleading as custody-only.

The government also corrected its description of the custody authority. It ultimately conceded that Suri was held under the discretionary provision in 8 U.S.C. section 1226(a), after initially describing detention as mandatory. The majority used the distinction between detention and removal, the statutory context and the Supreme Court’s detention analysis in Jennings v. Rodriguez to conclude that these three review provisions did not bar his petition.

Substance still controlled. As the majority explained in its Suri discussion of disguised removal challenges, changing the label cannot turn a claim that actually contests the commencement of removal proceedings into a separate detention claim. Counsel must examine the factual allegations, the legal question and the requested order together.

Other judges read the review rules differently

Judge Wilkinson’s dissent read Congress’s language more broadly. He viewed Suri’s detention and the start of removal proceedings as connected parts of the same government action. On that reading, section 1252(b)(9) required the constitutional challenge to proceed through the immigration process and eventual court-of-appeals review. He emphasized Congress’s decision to consolidate review, including legal and constitutional questions, and the mechanisms for reviewing those claims in a petition for review. The majority instead stressed the distinct injury from custody and the limits of later review as a remedy for that injury.

A decision issued two days earlier sharpened that disagreement. In Mahdawi v. Trump, No. 25-1113 (2d Cir. July 21, 2026), the Second Circuit held that section 1252(b)(9) channeled Mahdawi’s claims into the removal-review process. His petition sought to set aside the Secretary of State’s removability determination and an alleged speech-based removal policy, along with release. The court found the detention arguments intertwined with the challenge to removal, vacated the release order and directed dismissal of the habeas petition.

The Second Circuit also relied on an available procedure to contest classification as ineligible for immigration-judge bond review, often called a Joseph hearing. In Mahdawi’s discussion of that procedure, the government confirmed its availability, the court treated it as meaningful review, and Mahdawi had not used it. A successful classification challenge would permit consideration of bond. In distinguishing that case, the Suri majority pointed to the different government representation in Suri’s own case: The government had told the court that an immigration judge could not redetermine his custody.

For a detained person, these differences make the actual charge, custody authority, available administrative procedure, pleading and governing circuit important. A favorable result in one case needs to be read alongside the different reasoning and record in the other. In Suri’s appeal, Wilkinson would have dismissed for lack of subject-matter jurisdiction and expressly declined to decide the separate custodian and venue questions.

The preservation order protected an existing case

The district court had also ordered that Suri not be removed from the United States while the case was pending unless the court ordered otherwise. The Fourth Circuit upheld that protection under the All Writs Act, 28 U.S.C. section 1651. The Act permits writs in aid of a court’s jurisdiction; the majority explained that it supported jurisdiction obtained through another source.

The Suri court tied the order to this pending case. The district court had been concerned about possible imminent deportation, and removal could extinguish Suri’s claims and defeat its ability to decide them. The majority upheld a judicial order protecting that authority. Someone seeking comparable emergency protection needs counsel to assess the particular jurisdictional basis, threatened action and relief requested, and to seek an order addressing them.

What to preserve when location is changing

Suri’s record shows why an emergency chronology should separate an actual movement from the time counsel or family learned about it. Preserve the arrest location, each confirmed detention location, flight or transfer information, facility booking records, charging papers, locator results with timestamps, counsel’s appearance and requests for information. Keep the federal filing receipt and each order as well. A future hearing address, a transfer destination and the person’s location when a petition was filed can be three different facts.

The appeal ended with the Fourth Circuit affirming the rulings under review. Its decision kept Suri’s detention challenge in the Virginia court and upheld the preservation order. The practical task for another family is to give counsel a reliable account of custody, knowledge and the exact remedy needed, so the filing can address both where the case belongs and the court’s authority to hear the claim.
