The Supreme Court handed the Trump administration a major win on immigration enforcement Tuesday, ruling 6-3 in Blanche v. Lau that border officials can place returning green card holders on immigration parole based on suspicion of criminal activity, without first proving the crime by "clear and convincing evidence." Justice Ketanji Brown Jackson fired back in dissent, warning the majority had given federal agents a "massive blank check" to strip lawful permanent residents of their status at the border.
The decision, authored by Justice Clarence Thomas, reversed a Second Circuit ruling that had sided with Muk Choi Lau, a lawful permanent resident who was placed on parole by border officials in 2012 when he returned from a short trip abroad while facing an unresolved state charge of trademark counterfeiting. Lau later pleaded guilty and received probation, but the government moved to deport him, and the question of what standard applied at the moment of reentry climbed through the courts for years.
For the six-justice majority, the answer was straightforward: Congress never wrote a "clear and convincing evidence" requirement into the Immigration and Nationality Act, so courts had no business inventing one. For the three liberal dissenters, Jackson, joined by Justices Sonia Sotomayor and Elena Kagan, the ruling tears a hole in protections that lawful residents have relied on for decades.
Justice Thomas's majority opinion zeroed in on the text of the INA and dismissed the evidentiary standard the Second Circuit had applied as a judicial invention grafted onto the statute from unrelated Board of Immigration Appeals precedent.
Thomas wrote:
"The Second Circuit derived its clear-and-convincing-evidence requirement not from the statutory text, but from inapposite Board of Immigration Appeals precedent... We decline to read into the INA an additional clear-and-convincing-evidence burden on border officers entrusted with making 'quick judgments on the spot' when that burden is nowhere in the statute."
The practical effect is significant. Border officials may now place a returning lawful permanent resident on immigration parole, effectively suspending that person's green card status, based on a pending criminal charge. Deportation proceedings can begin before any conviction. And the burden shifts: the green card holder must prove legal entitlement to remain, rather than the government proving grounds for removal.
That framework matters well beyond any single case. It gives DHS officers wider discretion at ports of entry and removes a judicial check that lower courts had imposed. The ruling fell along familiar ideological lines, with the Court's six conservative justices in the majority, a pattern that has defined several consequential Supreme Court decisions this term.
Jackson's dissent did not hold back. She argued the majority had upended the statutory scheme Congress designed to protect lawful permanent residents from being treated as new arrivals every time they cross the border.
As Newsweek reported, Jackson wrote:
"With today's decision, the Court allows the Government to return an LPR to the status of 'seeking an 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 relevant statutory scheme, which guarantees that LPRs will not be 'regarded as seeking an admission' at the border unless certain exceptions apply."
She acknowledged that an acquitted green card holder would ultimately prevail against removal. But she called that acknowledgment hollow comfort.
"To be sure, if the paroled LPR ends up being acquitted, the Government's eventual effort to remove him on this basis will fail. But that is likely cold comfort to the LPR, who by then might have spent years in legal limbo (with only the protection of a temporary green card) or worse, in detention."
Jackson also called the ruling "a loophole vast enough to swallow protections", a characterization that captures the liberal wing's view that the decision eviscerates statutory safeguards for millions of green card holders who travel internationally.
The Department of Homeland Security wasted no time claiming the result. James Percival, DHS General Counsel, told Newsweek in an emailed response: "Today, the Supreme Court affirmed an important tool DHS has long used to prevent criminals from entering our country. Big win!"
That framing, "long used", is worth noting. The government's position was not that it needed new authority, but that courts had improperly restricted authority it already possessed under the INA. Thomas's majority agreed, finding that the Second Circuit had layered on a burden Congress never intended.
National Review noted the ruling was one of three immigration cases on the Court's docket this term, describing it as a decision that "struck a blow in favor of the immigration authorities in denying entry to green-card holders where they have committed crimes but have not yet been convicted." The case was decided June 23, 2026.
Muk Choi Lau's story is a useful window into what this ruling means in practice. Lau held a green card, lawful permanent resident status, and traveled abroad briefly in 2012. When he returned to the United States, border officials flagged him. He was facing an unresolved state charge of trademark counterfeiting at the time.
Rather than admitting him as a returning resident, officials placed him on immigration parole. That single administrative decision changed his legal footing entirely. Instead of standing as a lawful permanent resident with full rights, he was treated as someone seeking admission, a far more precarious status.
Lau eventually pleaded guilty to the counterfeiting charge and received probation. The government then initiated deportation proceedings. Lau challenged the process, and the Second Circuit sided with him, holding that the government needed clear and convincing evidence of a disqualifying crime at the moment of reentry before it could parole a returning green card holder.
The Supreme Court's reversal means the government's 2012 decision to parole Lau, made before any conviction, was lawful. And the precedent now applies to every green card holder who crosses a U.S. border.
The ruling arrives at a moment when the Supreme Court is actively shaping the boundaries of executive immigration power. The Court is also weighing cases tied to birthright citizenship, a restrictive asylum policy, and temporary legal protections for migrants fleeing war and natural disasters. Legal analysts have been closely tracking how this term's immigration docket will define the balance between presidential authority and statutory limits.
The Trump administration had urged the Court to take an expansive view of executive power in Blanche v. Lau, and it got what it asked for. The decision reinforces the principle that border enforcement officers need operational flexibility, and that courts should not impose evidentiary hurdles the statute does not contain.
For immigration hawks, the logic is clean: if Congress wanted to require clear and convincing evidence before border agents could act, it would have said so. The INA does not. End of analysis.
For the dissent, the concern runs deeper than one case. Jackson's warning about "years in legal limbo" points to a structural problem: green card holders who are charged but not convicted could find themselves stripped of status, placed in parole, and forced into removal proceedings that drag on while their criminal case is still pending. If they are acquitted, they may eventually prevail, but only after enduring the full weight of the deportation system.
That tension, between enforcement efficiency and due process for lawful residents, is real. But the majority's answer is that Congress, not the courts, is the proper body to resolve it.
Just The News reported that the case also carries implications for how future administrations use parole authority more broadly. The Biden administration granted parole to an estimated 2.86 million foreign nationals, according to the Center for Immigration Studies. James Rogers, senior counsel at America First Legal, told the outlet that limiting judicial review of parole decisions could "make it significantly harder in the future to challenge left-wing administrations' attempts to open the borders and use parole again to let in aliens because there would be no review of those decisions in court."
That observation cuts in an unexpected direction. A ruling that strengthens executive enforcement power today could, in theory, strengthen executive discretion to loosen enforcement tomorrow. The scope of the tool depends on who holds it.
Several questions remain open. The decision clearly applies to green card holders returning from international travel, but its full scope is not yet defined. Does it extend to every lawful permanent resident who crosses a U.S. border, regardless of the nature of the trip or the severity of the alleged crime? The opinion, as reported, does not draw those lines explicitly.
Nor does the ruling address what happens when the underlying charge is minor, or when it is ultimately dismissed rather than resolved by acquittal or conviction. Jackson's dissent flagged the problem of prolonged uncertainty, but the majority did not prescribe a remedy for it.
The Department of Justice did not respond to Newsweek's request for comment. The identities of the six justices in the majority, beyond Thomas, were not specified in the reporting, though the 6-3 split along ideological lines leaves little mystery. This term has produced a series of high-profile rulings that continue to define the Court's conservative majority.
Jackson's dissent frames the ruling as a threat to lawful permanent residents. But the case involved a man who was, in fact, guilty of the crime he was suspected of when border agents flagged him. He pleaded guilty. He received probation. The government's instinct at the border, that something was wrong, turned out to be correct.
The dissent's hypothetical parade of innocents languishing in "legal limbo" is a policy argument, not a textual one. And the majority said as much: if Congress wants a higher evidentiary bar at the border, Congress can write one. Courts should not fabricate standards the statute does not contain.
That principle, that judges interpret law rather than invent it, has animated conservative jurisprudence across multiple courts in recent years. It is not a blank check. It is a boundary line, drawn where the Constitution places it: between the branch that writes the law and the branch that reads it.
Jackson warned about a blank check. What the majority actually delivered was a receipt, for authority Congress already granted and courts had no business withholding.
