Summary: New York Gov. Kathy Hochul pardoned Keisy Guerrero Mariano in late August, prompting the Supreme Court to declare Genalo v. Black moot. The dispute asked whether prolonged immigration detention can require a bond hearing under the Fifth Amendment—a question the Second Circuit answered in the affirmative in May 2024. Solicitor General John Sauer says the administration will seek another case to present the issue to the Court, while critics argue the pardon undercut a major legal ruling.
Hochul Pardon Moots Supreme Court Case Over Bond Rights for Noncitizens
FILE - New York Democratic Gov. Kathy Hochul pardoned Keisy Guerrero Mariano in late August.
New York Gov. Kathy Hochul’s late August pardon of Keisy Guerrero Mariano has removed a high-profile immigration dispute from the Supreme Court’s docket, after the Court concluded the case is now moot. The case, Genalo v. Black, asked whether noncitizens detained for prolonged periods— including lawful permanent residents—are entitled to a bond hearing when detention becomes excessive.
Mariano, identified in court records as “Keisy GM,” was arrested by Immigration and Customs Enforcement (ICE) in 2020 based on a 2015 second-degree assault conviction for which he had served time. He spent nearly two years in ICE custody and was released in 2022 following a nationwide injunction tied to COVID-19 health concerns. In November 2021, U.S. District Judge John P. Cronan denied Mariano’s habeas petition; in May 2024 the Second Circuit reversed, holding that excessively long immigration detention may trigger Fifth Amendment due-process protections and require a bond hearing.
The government appealed to the Supreme Court, which had agreed on June 15 to hear the case. But after Hochul issued the pardon just as the government’s brief was due, Solicitor General John Sauer agreed that Genalo v. Black is moot. Sauer said the administration will seek an "alternative vehicle" to present the legal question—aiming to have the issue resolved in the 2026–27 term if necessary.

The underlying litigation was brought by plaintiffs including Carol Williams Black, a Jamaican national, and Mariano, both of whom were convicted of crimes and detained by ICE. The Court dismissed the portion of the case involving Black as moot after he left the United States and filed a declaration saying he would not return. Black was convicted in 2000 of sexually abusing a child under age 11.
Reactions and Wider Implications
Hochul’s pardon has drawn sharp criticism from some legal officials. Iowa Solicitor General Eric Wessan posted on X that it was "pretty wild" for a governor to pardon an aggravated felon in a way that both prevents deportation and preempts a Supreme Court ruling on a long-running legal question. The Department of Justice has signaled it will continue to try to bring the issue before the Supreme Court through another case.
Key Legal Question: Whether prolonged immigration detention without a bond hearing violates the Fifth Amendment’s due-process clause, and if so, what procedural protections detained noncitizens must receive.
For now, Hochul’s pardon has removed this particular vehicle for resolving that question, leaving lower-court rulings—like the Second Circuit’s May 2024 decision—in place until the Supreme Court can review the issue in another case.
