Supreme Court Declines to Hear Case on Indefinite Immigrant Detention

Supreme Court Declines to Hear Case on Indefinite Immigrant Detention

The Supreme Court has opted not to hear a significant immigration case, Genalo v. Black, which questioned whether immigrants could be held in detention indefinitely without the opportunity for a bond hearing. The court's decision to not take the case means a lower court's ruling, which stated that due process bars prolonged detention without such hearings, will stand for now.

Case Background

The case, Genalo v. Black, involved two lawful permanent residents detained during the Trump administration. They were arrested years after committing crimes for which they had already served prison sentences. Federal law mandates that noncitizens convicted of certain crimes or suspected of terrorism be taken into custody for deportation proceedings, without explicit allowance for challenging their detention while their cases are pending. One of the individuals, Keisy Guerrero Mariano, spent 21 months in immigration detention without a bond hearing, a period longer than his original prison sentence for assault.

Legal Challenge and Lower Court Ruling

Both individuals sued, arguing that prolonged detention without a chance to seek release through a bond constituted a violation of their due process rights. The federal appeals court agreed, ruling that the executive branch cannot detain such individuals for an "unreasonably prolonged period" without offering a bond hearing.

Case Dismissal and Pardon

Prior to the Supreme Court's decision, the case became moot. Carol Williams Black, one of the individuals, was released and has since left the United States. The case against Keisy Guerrero Mariano was effectively resolved when New York Governor Kathy Hochul granted him a pardon for the conviction that served as the sole basis for his detention. The pardon document specifically stated it provided "relief from removal." Guerrero Mariano's lawyers had sought this pardon shortly before his brief to the Supreme Court was due.

Supreme Court's Rationale and Implications

With the case now moot, the Supreme Court dismissed it. The Trump administration's Justice Department joined a stipulation calling for the dismissal, acknowledging that a lawful permanent resident without a conviction might not be subject to detention.

Immigration lawyers had expressed concern that the Supreme Court might have ruled in favor of indefinite detention, citing previous decisions that have allowed the deportation of immigrants to dangerous regions and weakened protections against torture. While the Second Circuit's ruling in Genalo v. Black provided a potential safeguard, its vagueness on what constitutes an "unreasonably prolonged period" left uncertainty. The Supreme Court's decision to avoid ruling on the core issue means that the question of whether immigrants can be detained indefinitely without bond hearings remains legally unresolved, awaiting a future case with a clear legal dispute.
