The legal battle over immigration enforcement in Southern Nevada has reached the state’s highest court.
This week, the American Civil Liberties Union (ACLU) of Nevada filed a petition asking the Nevada Supreme Court to review the legality of a partnership between the Las Vegas Metropolitan Police Department (Metro) and U.S. Immigration and Customs Enforcement (ICE).
The petition follows a lower court’s dismissal of a lawsuit challenging the “287(g)” program—a federal initiative that allows local law enforcement agencies to assist in federal immigration enforcement.
The Program at the Center of the Dispute
Under the 287(g) agreement, which Sheriff Kevin McMahill signed in May 2025, trained staff at the Clark County Detention Center are authorized to process ICE warrants. This allows the jail to flag foreign-born individuals during the booking process and hold inmates for up to 48 hours after they would otherwise be released on local charges, giving ICE time to take them into custody.
Between December 2025 and March 2026, Metro reported that ICE took custody of at least 240 inmates through this program.
The Legal Impasse
The current legal challenge stems from a lawsuit involving Sergio Morais-Hechavarria, an inmate who was deported after being held past the 48-hour window.
Last month, District Court Judge Monica Trujillo dismissed the case, ruling that the ACLU lacked “standing”—a legal term meaning the party bringing the suit does not have a sufficient connection to or harm from the law or action challenged. Because Morais-Hechavarria had already been deported, the court found that a favorable ruling would not benefit him personally.
By dismissing the case on procedural grounds, the District Court did not rule on the central question: whether Metro has the legal authority under Nevada state law to enter into such an agreement with the federal government.
Differing Perspectives on Authority and Safety
The dispute highlights a fundamental disagreement over the role of local police in federal immigration matters.
Arguments for the Partnership: Proponents of the 287(g) program, including Sheriff McMahill, argue that it is a necessary tool for public safety.
Before the formal agreement, Metro was already flagging inmates suspected of violent crimes, DUIs, and domestic violence. The partnership streamlines the process of ensuring that individuals with federal immigration warrants are handed over to the proper authorities rather than being released back into the community.
Supporters often point to federal mandates, such as the Laken Riley Act, as justification for expanded cooperation between local and federal agencies to address criminal activity among non-citizens.
Arguments Against the Partnership: The ACLU and other critics argue that Metro overstepped its bounds.
They contend that local police powers are granted by the State Legislature, and since the Legislature has not explicitly authorized local agencies to enforce federal civil immigration law, the 287(g) pact is an unlawful use of local resources. Critics also argue that these partnerships can lead to “mass deportation” efforts that undermine civil liberties and discourage immigrant communities from interacting with local police for fear of deportation.
What Happens Next?
The Nevada Supreme Court must now decide whether to take up the case. If the justices agree to hear the petition, they will likely focus on the issue of standing—determining whether an advocacy group can challenge a policy even if the original plaintiff is no longer in the country—and whether the state’s statutes allow local police departments to execute federal immigration detainers.
As of Tuesday, the Supreme Court had not yet docketed the case, and both Metro and ICE have declined to comment on the pending litigation.
The eventual ruling could set a significant precedent for how much authority Nevada sheriffs have in cooperating with federal immigration officials.
