The Supreme Court on Friday dismissed a case that had been set for oral argument next month after the federal government and the respondent jointly agreed that the controversy had become moot, abruptly ending a high-stakes immigration dispute over the constitutional rights of long-term detainees. The case, Genalo v. Black, had been scheduled for argument on Tuesday, Oct. 13, and was poised to answer a pivotal question left open by the Court in 2018: at what point, if any, does prolonged immigration detention under Section 1226(c) of the Immigration and Nationality Act trigger a constitutional right to a bond hearing under the Fifth Amendment’s due process clause. The dismissal leaves only one argument currently scheduled for Oct. 13, reducing the Court’s October sitting to just six total arguments.
Key Question Left Lingering: When Does Detention Require a Bond Hearing?
The central legal issue in Genalo v. Black involved the detention of noncitizens, including lawful permanent residents, who have committed certain crimes and are awaiting removal proceedings. Section 1226(c) of the Immigration and Nationality Act mandates the detention of such individuals, explicitly prohibiting their release except on narrow, witness-protection grounds. The question before the justices was whether, after a lengthy period of detention, the Constitution itself demands a bond hearing where the government must justify continued incarceration.
This issue traces back to the Supreme Court’s 2018 decision in Jennings v. Rodriguez, where the Court held that Section 1226(c) does not, on its own, require periodic bond hearings. However, the justices in that case specifically declined to resolve the constitutional due process question — whether, at some point, prolonged detention without a hearing becomes constitutionally impermissible. That unresolved question has percolated in the lower courts for years, creating a circuit split that the Supreme Court had hoped to address in the now-dismissed case.
In its petition for review, the federal government — under then-Solicitor General Elizabeth Prelogar — had urged the Court to take up Genalo v. Black to squarely answer that lingering constitutional question. The government argued that the U.S. Court of Appeals for the 2nd Circuit had erred when it ruled that the two men at the center of the case were entitled to bond hearings because their detention had become so prolonged that it violated due process. The 2nd Circuit’s decision, the government contended, wrongly expanded constitutional protections beyond what Congress intended when it enacted the mandatory detention provision.
The Origins of the Case: Two Men, One Case, Two Paths to Mootness
The case began with two men detained under Section 1226(c). One of them, Carol Williams Black, left the United States while the government’s petition for review was pending and filed a declaration with the Court stating he had no intention of returning. The parties agreed that his claim was moot, and when the Supreme Court granted the petition on June 15, it narrowed the case to focus solely on the other individual, identified in court documents as Keisy G.M.
Keisy G.M. had been detained by immigration officials for 21 months after being convicted of assault. But the case’s viability was already in question when the Court granted review. The justices acknowledged as much, ordering the litigants to brief whether G.M.’s claim was also moot. At that point, the mootness concern stemmed from the fact that G.M. had been released from physical custody in 2022.
A Pardon Moots the Case Entirely
The mootness question took on entirely new dimensions in late August, when New York Gov. Kathy Hochul granted G.M. a full pardon with respect to his assault conviction. This was not a routine development — it fundamentally altered the legal landscape of the case. As ACLU National Legal Director Cecillia Wang wrote in G.M.’s merits-stage brief, the pardon meant that G.M. was “no longer deportable” and therefore “no longer subject to mandatory detention under Section 1226(c).” The legal predicate for the entire controversy — his deportability based on that specific conviction — had been eliminated.
In a letter to Clerk of the Court Scott Harris dated Friday, Acting Solicitor General D. John Sauer confirmed the government’s agreement that the case was now moot. “The government agrees with G.M. that his habeas case is now moot,” Sauer wrote, pointing directly to the governor’s pardon as the dispositive event. Sauer and Wang subsequently filed a joint stipulation to dismiss the case, which the Court accepted later that day.
Sauer also indicated that the Justice Department intends to bring the issue back to the Court soon through a new petition for review, signaling that the government views the underlying legal question as too important to leave unresolved merely because of the procedural oddities that doomed this particular case.
What Is Section 1226(c) and Why Does It Matter?
Section 1226(c) of the Immigration and Nationality Act is a mandatory detention provision that applies to noncitizens who have been convicted of certain crimes, including aggravated felonies, crimes of moral turpitude, and controlled substance offenses. The statute requires the Department of Homeland Security to take such individuals into custody and hold them without bond while removal proceedings are pending. The only statutory exception is for witness-protection purposes, a narrow carve-out that the federal government has historically interpreted extremely restrictively.
The law has been a flashpoint in immigration policy for decades. Proponents argue that mandatory detention is essential for public safety and to ensure that noncitizens with criminal records appear for their removal hearings. Critics, including civil liberties organizations and a growing number of federal judges, contend that the statute can result in indefinite detention without any meaningful review — a practice they argue violates fundamental principles of due process enshrined in the Fifth Amendment.
The constitutional question is straightforward but legally complex: Does the Due Process Clause of the Fifth Amendment require the government to provide a bond hearing after a certain period of mandatory detention, and if so, what must the government prove to justify continued detention? The Supreme Court’s decision in Jennings v. Rodriguez held that the statute itself does not provide for periodic bond hearings, but the Court explicitly left open the possibility that the Constitution might require them.
The 2nd Circuit’s Reasoning and the Circuit Split
The U.S. Court of Appeals for the 2nd Circuit, in its decision that the Supreme Court had agreed to review, held that prolonged detention under Section 1226(c) must eventually give way to due process protections. Specifically, the 2nd Circuit ruled that once a noncitizen’s detention becomes “prolonged” — a determination the court left to case-by-case analysis — the government must provide a bond hearing at which it bears the burden of proving that the individual poses a danger to the community or a flight risk. If the government cannot meet that burden, the detainee must be released pending the conclusion of removal proceedings.
This decision placed the 2nd Circuit in direct conflict with other federal appellate courts that have interpreted the statute and the Constitution more narrowly. Some circuits have held that Section 1226(c) detention is categorically constitutional, regardless of its duration, while others have required bond hearings but disagreed on the applicable legal standard. The Supreme Court had granted review in Genalo v. Black precisely to resolve this circuit split and provide a uniform national standard.
Implications of the Dismissal for Immigration Law and the October Term
The dismissal of Genalo v. Black is a significant procedural setback for the federal government, which had sought a definitive ruling from the Supreme Court on the due process question. The government’s stated intention to file a new petition for review suggests that it will look for another vehicle to bring the issue before the justices, potentially in the current term or the next. However, finding a suitable case — one that is not moot and that cleanly presents the constitutional question — may take time.
For noncitizens detained under Section 1226(c), the dismissal means continued legal uncertainty. In jurisdictions like the 2nd Circuit, bond hearings will remain available to those who can show their detention has become prolonged. In other circuits, detainees may have no such right. This patchwork of protections is precisely the kind of inconsistency the Supreme Court typically steps in to resolve.
The timing of the dismissal also has immediate practical consequences for the Supreme Court’s October sitting. With Genalo v. Black removed from the argument calendar, only one case remains scheduled for Oct. 13 — Beaird v. United States — bringing the total number of arguments for the October sitting to just six. This unusually light calendar reflects the Court’s deliberate pace in selecting and scheduling cases, as well as the procedural unpredictability that can derail even the most carefully vetted petitions.
What Happens Next: The Path Forward for the Due Process Question
The most immediate question following the dismissal is what vehicle the federal government will use to bring the Section 1226(c) due process issue back to the Supreme Court. Sauer’s letter to the clerk indicated that the Justice Department is already working on a new petition, but the government must find a case that presents a live controversy — meaning the detainee must still be in custody and must not have received a pardon or other relief that would render the case moot.
The ACLU, which represented Keisy G.M., has made clear that it views the pardon as a complete victory for its client, but the organization is likely to oppose any future government effort to restrict due process protections for long-term detainees. The civil liberties group may also seek to bring its own test case to the Court, arguing that the Constitution requires bond hearings regardless of the statutory framework.
The pardon from Gov. Hochul adds a fascinating political dimension to the case. Whether the governor’s action was intended to spare G.M. from deportation, to protect New York’s interests in the litigation, or to send a broader message about immigration enforcement is unclear. But the practical effect is undeniable: a single state executive action derailed the federal government’s carefully constructed Supreme Court strategy.
For now, the due process rights of noncitizens detained under Section 1226(c) remain in a state of legal limbo. The Supreme Court has now twice declined — first in Jennings v. Rodriguez and now in Genalo v. Black — to answer the constitutional question definitively. The lower courts will continue to apply divergent standards, creating unequal access to bond hearings depending on where a detainee is held. This is not a sustainable situation for a federal immigration system that is supposed to operate uniformly across the country, and it all but guarantees that the Supreme Court will have to confront the issue again sooner rather than later. When it does, the justices will have to decide not just the legal parameters of due process in the immigration detention context, but also whether the Constitution can tolerate a system in which a single state pardon can short-circuit a major test of federal immigration authority.
