New York Gov. Kathy Hochul pardoned a convicted felon just as a major Supreme Court immigration case reached its deadline, a move that rendered the case moot and blocked the Trump administration from challenging noncitizen detention rules.
Solicitor General John Sauer agreed Friday that the case, Genalo v. Black, is now moot after Hochul issued her late-August pardon of Keisy Guerrero Mariano, a lawfully present Dominican citizen who had pleaded guilty to second-degree assault. The pardon pulled the legal ground out from under a case the Supreme Court had agreed to hear on June 15, one the Trump administration viewed as a path to overturning a Second Circuit ruling that required bond hearings for noncitizens held in prolonged immigration detention.
The timing alone raises questions. Hochul issued the pardon just as the administration's brief was due, Fox News Digital reported. The governor, described as staunchly opposed to President Donald Trump's immigration enforcement efforts, has not responded to a request for comment on her decision.
Mariano's case stretches back nearly a decade. He was convicted of second-degree assault in 2015, served time for it, and was first arrested by ICE officers in 2020 based on that conviction. He then spent nearly two years in immigration detention before being released in 2022 under a nationwide injunction that required ICE to release detainees because of COVID-19 health risks.
While detained, Mariano, identified in court documents as "Keisy GM", sought a habeas corpus hearing, arguing his prolonged detention without a bond hearing violated his constitutional rights. Judge John P. Cronan of the U.S. District Court for the Southern District of New York denied that request in November 2021.
But the Second Circuit reversed Cronan's decision in May 2024, ruling that the government must grant noncitizens a bond hearing once their detention becomes "unreasonably long." The appeals court held that failing to provide such a hearing violates the Fifth Amendment's guarantee of due process, the constitutional provision that bars the government from depriving any person of life, liberty, or property without fair legal proceedings.
That ruling set up a direct collision with the Trump administration's position. The administration argued that noncitizens, including those with green card status, have no legal right to a bond hearing during prolonged detention if they committed crimes that qualify for mandatory deportation. The case was poised to resolve a split among federal appeals courts on this question, with the Eighth Circuit holding that due process places no time limit on detention pending deportation, while the Second and Third Circuits ruled the opposite.
The case had already lost one plaintiff before Hochul acted. Carol Williams Black, a Jamaican national with lawful permanent resident status, was the other party in Genalo v. Black. Black had been convicted in New York in 2000 of sexually abusing a minor under the age of 11. He left the United States and filed a court declaration stating he would not return, prompting the Supreme Court to rule his portion of the case moot.
That left Mariano as the sole remaining plaintiff, and the only thread keeping the case alive. Hochul's pardon cut that thread. With both plaintiffs gone, the Supreme Court had no live controversy to decide.
The sequence is worth spelling out plainly. A governor who opposes the president's immigration enforcement pardoned a convicted felon at the precise moment the pardon would prevent the nation's highest court from ruling on a question that could have strengthened the government's power to detain illegal immigrants and criminal noncitizens. Whatever Hochul's stated reasons, and she has offered none publicly, the practical effect was to shield a lower-court ruling favorable to noncitizen detainees from Supreme Court review.
Iowa Solicitor General Eric Wessan, posting on X, did not hold back. He called the move "pretty wild."
"Pretty wild to fully pardon an aggravated felon to (1) stop the felon from getting deported and (2) stop the Supreme Court from ruling on an issue. (Especially as this litigation has been going on for years)"
In a follow-up post, Wessan broadened his criticism beyond Hochul.
"I wonder how many non-American felons Governors like Hochul will choose to fully pardon and free to avoid them facing consequences for their actions"
The Trump administration is not walking away from the legal fight. Sauer indicated the administration will seek an "alternative vehicle", a different case raising the same legal question, to bring the issue before the Supreme Court during its 2026, 27 term. The underlying circuit split remains unresolved, and the federal law at the center of the dispute, which requires certain criminal noncitizens to be detained pending removal, still applies nationwide with conflicting interpretations depending on which appeals court covers a given jurisdiction.
Finding a new case will take time. The Supreme Court's current term will not produce a ruling on noncitizen detention rights, and the administration will need to identify a plaintiff and procedural posture that cannot be mooted by another well-timed pardon or departure. The delay gives governors and advocacy groups opposed to immigration enforcement more runway to challenge detention policies in friendly circuits.
The broader pattern is familiar. Progressive state officials have repeatedly used their authority, whether through sanctuary policies, non-cooperation orders, or now pardons, to frustrate federal immigration enforcement. Hochul's pardon fits neatly into that pattern, but it goes a step further: rather than simply refusing to cooperate with ICE, she used the pardon power to dismantle a Supreme Court case from the outside.
This comes as the Supreme Court has been a frequent battleground between the Trump administration and its opponents across a range of policy areas. Democrats have grown increasingly frustrated with the Court's willingness to side with the administration on contested legal questions.
Some on the left have responded to that frustration by proposing structural changes to the judiciary. Former Vice President Kamala Harris has called for expanding the Supreme Court, a position that reflects the progressive wing's view that the current Court majority is an obstacle to their agenda.
Several facts remain unclear. Hochul's office has not explained why she pardoned Mariano or whether the timing was coordinated to affect the Supreme Court case. Fox News Digital reached out for comment and received no response. The pardon's effect on Mariano's immigration status is also unresolved, whether he remains subject to removal proceedings, or whether the pardon eliminates the criminal conviction that triggered ICE's mandatory detention authority in the first place.
Meanwhile, the Trump administration has shown a pattern of returning to the Supreme Court when lower courts or political opponents block its policy goals. Sauer's pledge to find a new vehicle suggests the administration views the noncitizen detention question as too important to abandon.
The stability of the current Court majority, underscored by Justice Alito's confirmation that he intends to remain on the bench, gives the administration reason to believe a future case could produce a favorable ruling. But the 2026, 27 term is a long way off, and the Second Circuit's rule requiring bond hearings for prolonged detention remains the law in the meantime across its jurisdiction.
Governors have broad pardon authority. No one disputes that. But when a governor uses that authority to pardon a convicted felon at the exact moment it collapses a Supreme Court case her political allies wanted to avoid, and then refuses to explain why, the pardon stops looking like mercy and starts looking like obstruction by another name.
