The Supreme Court ruled 6-3 on Tuesday that federal border agents can deny re-entry to green card holders accused of crimes without first proving the charges by "clear and convincing evidence", a decision that hands immigration enforcement officials a far stronger hand at U.S. ports of entry.

Justice Clarence Thomas wrote the majority opinion in Blanche v. Lau, holding that agents need only show "reason to believe" a lawful permanent resident committed a disqualifying offense. The three liberal justices dissented.

The ruling settles a dispute that has wound through the courts for more than a decade, rooted in the 2012 case of Muk Choi Lau, a Chinese citizen and green card holder who was flagged at John F. Kennedy International Airport in New York while returning from a trip to China. At the time, Lau faced New Jersey state charges for trademark counterfeiting. Border officials deemed him inadmissible but conditionally allowed him back into the country. A year later, he pleaded guilty. Then the government ordered him deported.

Lau fought back, arguing the counterfeiting conviction did not amount to a "crime involving moral turpitude", the statutory threshold under the Immigration and Nationality Act. A federal appeals court sided with him and tossed the immigration court's removal order, finding that officials had not established clear and convincing evidence of a disqualifying crime at the moment they paroled him back in.

Thomas: The law doesn't require that standard

The majority disagreed. Thomas wrote plainly that the statute imposes no such burden on border agents at the point of entry, as ABC News reported.

"The Immigration and Nationality Act does not impose that requirement."

The practical effect: immigration officers at a port of entry no longer need a conviction, or even formal proof of one, before treating a returning green card holder as someone "seeking admission" rather than someone entitled to re-enter. If the government can later show the person was eventually convicted, that is enough.

Solicitor General D. John Sauer had pressed the Court to overturn the appeals court ruling, calling it a result that "defies common sense and reality," the Washington Examiner reported. The Justice Department warned that upholding the lower court's decision would "create significant practical consequences for the Department of Homeland Security" over its ability to parole noncitizens it may later seek to remove.

The Court's six-justice majority agreed. The decision lands squarely on the side of enforcement, and against the notion that green card holders enjoy the same procedural protections as citizens when they leave and attempt to return.

Jackson warns of a 'massive blank check'

Justice Ketanji Brown Jackson authored the dissent, joined by Justices Sonia Sotomayor and Elena Kagan. Her language was pointed.

"I worry that the court has now handed the government a massive blank check."

Jackson argued the ruling upends the statutory framework by letting the government retroactively reclassify a lawful permanent resident as someone "seeking admission", and then use a later conviction to justify the denial.

"With today's decision, the Court allows the government to return an LPR to the status of 'seeking admission' upon his entry at the border, so long as the government is able to show later that he was eventually convicted. That sequencing undermines the plain terms and basic operation" of the law.

That objection amounts to a process complaint. The majority's answer is that Congress wrote the Immigration and Nationality Act to give border agents broad gatekeeping authority, and that the appeals court invented a standard the statute never contained.

The case arrives amid a packed Supreme Court docket that includes several other high-stakes immigration and executive-power disputes this term.

What the case means for immigration enforcement

The ruling's significance extends well beyond one man's counterfeiting conviction. Under existing immigration law, green card holders who legally leave the United States for short periods are generally entitled to re-enter, unless they fall into certain statutory exceptions, including conviction for or admission to a crime involving moral turpitude.

Before Tuesday's decision, a federal appeals court had effectively required immigration officers to meet a high evidentiary bar at the moment of parole. That created a practical obstacle: agents at a busy port of entry often lack the resources to assemble courtroom-quality evidence on the spot. The appeals court's standard, Sauer argued, made it harder for the government to act on credible criminal information in real time.

James Rogers, senior counsel at America First Legal, framed the stakes in straightforward terms. "It's a lot easier to remove an alien in that sort of situation," Rogers told Just The News.

Rogers also noted the narrow design of the parole statute itself: "The parole statute is supposed to only allow a narrow exception where a DHS officer is allowed to admit aliens on a case-by-case basis if the DHS officer determines that there's a significant humanitarian need or significant national benefit to letting the alien in."

The Court's ruling reinforces that parole is not a grant of full legal admission, and that someone paroled into the country remains subject to removal if the government later presents evidence of a disqualifying crime.

That distinction matters enormously in the current enforcement environment. The Court has taken up several related cases testing the boundaries of federal authority over criminal immigrants, including whether ICE can hold certain noncitizens without bond hearings.

The broader pattern

National Review described the ruling as a "significant win for immigration enforcement efforts" and part of a broader set of immigration cases on the Court's docket this term. The decision fell along ideological lines, the six conservative-appointed justices in the majority, the three liberal-appointed justices in dissent.

That alignment is worth noting. The dissent's core worry, that the government now holds a "blank check", assumes that lowering the evidentiary burden at ports of entry will lead to abuse. But the majority's position rests on a simpler premise: Congress wrote the law this way. Border agents are not prosecutors. They are gatekeepers. And the statute gives them the authority to act on reasonable belief, not courtroom proof.

Lau's own case illustrates the gap the appeals court tried to fill, and the absurdity of the standard it created. He arrived at JFK facing active state criminal charges. Border agents flagged him. He was conditionally let back in. He then pleaded guilty. And yet the appeals court said the government couldn't use that conviction to remove him because agents hadn't proved the crime at the moment of parole.

The Supreme Court said that reading of the law was wrong.

The federal government has been pressing its authority on multiple fronts. The DOJ recently moved to strip citizenship from naturalized Americans accused of terrorism, murder, and fraud, another signal that the administration views immigration status as conditional on lawful conduct, not as an irrevocable entitlement.

Lau, for his part, continues to contest his removal. His argument, that trademark counterfeiting does not qualify as a crime of moral turpitude, remains unresolved. But the procedural shield he relied on, the requirement that agents prove their case at the border before acting, is gone.

Several questions remain open. The ruling's precise scope, whether it applies retroactively to green card holders already in the country, or only to those arriving at ports of entry, is not fully addressed. Nor does the opinion identify which specific federal agency (CBP, ICE, or another DHS component) bears operational responsibility under the new standard. Those details will likely be tested in future cases.

The Court has shown little appetite this term for expanding procedural protections that slow federal enforcement action, a pattern the liberal justices have noticed and objected to.

The bottom line

For years, a legal fiction persisted in some federal courts: that a green card holder could return to the United States facing criminal charges, plead guilty, and still claim the government had no right to remove him because agents hadn't assembled enough proof at the airport. The Supreme Court ended that fiction on Tuesday.

The Immigration and Nationality Act gives border agents the authority to act on reasonable belief. Six justices read the statute and said so. Three justices worried about blank checks. But the real blank check was the one the appeals court handed to criminal immigrants, and the Court just tore it up.
