The Supreme Court on Tuesday declined to hear Florida's lawsuit against California and Washington state over their issuance of commercial driver's licenses to illegal immigrants, a case born from a fatal highway crash and a dispute over whether federal immigration law bars the practice. Justices Clarence Thomas and Samuel Alito dissented, arguing the Court had no choice but to take the case.

Florida brought the suit directly to the high court under its original jurisdiction, the constitutional provision that makes the Supreme Court the only forum for legal disputes between states. The majority turned it away without explanation. Thomas, in a written dissent, said the Court was shirking an obligation the Constitution does not allow it to dodge.

The case centers on a straightforward question with life-or-death stakes: Can states issue commercial driver's licenses to people who are in the country illegally and who may not be able to read English road signs, when federal law appears to prohibit both?

A fatal crash, a license that shouldn't have existed

The lawsuit traces back to a 2024 crash in Florida that killed three people. AP News reported the crash involved a driver named Harjinder Singh, an Indian national who was not a U.S. citizen or legal permanent resident. Singh held valid commercial driver's licenses from both California and Washington state.

Federal law requires CDL applicants to pass a driving test, demonstrate sufficient understanding of the English language, and show appropriate immigration status. Florida alleged that California and Washington were issuing licenses in open defiance of those requirements.

Florida Attorney General James Uthmeier, a Republican, led the suit. In its filing, Florida did not mince words:

"California's and Washington's decision to endanger their own citizens is reprehensible. But commercial drivers routinely cross state lines, endangering citizens of other States."

That framing, that the danger doesn't stay within the borders of the states creating it, is what made the case an inter-state dispute in the first place. And it is precisely why Thomas said the Court was obligated to hear it.

Thomas: The Court left Florida with nowhere to go

Fox News detailed the substance of Thomas's dissent, which laid out the federal requirements and the facts of the Singh crash in pointed terms. Thomas wrote:

"An illegal alien who cannot read English road signs cannot drive an 80,000-pound tractor-trailer. [Federal law] and regulations prohibit States from providing commercial driver's licenses to applicants unless they pass a driver's test, sufficiently understand the English language, and show appropriate immigration status."

Thomas also addressed the jurisdictional question head-on:

"If this Court does not exercise jurisdiction over a controversy between two States, then the complaining State has no judicial forum in which to seek relief."

That point deserves emphasis. When one state sues another, no lower court has the authority to hear the case. The Constitution gives the Supreme Court exclusive original jurisdiction. If the justices refuse to take it up, the dispute simply has no courtroom, anywhere.

Thomas framed the refusal as a constitutional failure, not merely a procedural choice. He argued that when states entered the Union, they traded away their sovereign right to resolve disputes with other states through other means. The Court, he wrote, was supposed to be the replacement.

"By entering the Union, States agree to instead have such disputes resolved by this Court."

Alito joined in dissent. The article does not indicate whether he wrote separately or simply joined Thomas's opinion.

The ideological composition of the current Court has drawn intense scrutiny in recent years, and this case adds another data point. Even with a 6-3 conservative majority, only two justices voted to hear a case that directly implicates federal immigration law, public safety, and the constitutional role of the Court itself.

California and Washington push back

Both defendant states filed responses urging the Court to stay out. California called Florida's claims "patently meritless" and said the suit "misinterprets a key state law." The state did not elaborate publicly on which law or how it was being misread.

Washington state raised a different concern, a slippery-slope argument about what kinds of inter-state disputes the Court might invite if it opened this door. In its filing, Washington asked:

"Can States bring nuisance claims against each other in this Court alleging that lax vaccination policies or firearm restrictions in one state are causing harm in another? The Court should not open that door."

That argument has a certain internal logic. But it also has an obvious weakness: Florida's complaint was not about abstract policy disagreements. It was about a specific federal regulatory framework, CDL eligibility, that both states allegedly violated, and a specific crash that killed three specific people.

Republican-led Florida accused both Democratic-led states of openly defying immigration laws. Newsmax noted that a federal appeals court had separately blocked Trump administration restrictions on immigrant CDL eligibility, adding another layer to the ongoing legal fight over who controls the licensing pipeline.

Federal law vs. state practice

The core legal question is not complicated. Federal regulations set minimum standards for commercial driver's licenses. Those standards include English-language proficiency and lawful immigration status. Florida alleged that California and Washington were issuing CDLs to applicants who met neither requirement.

The states denied it. But the facts of the Singh case suggest the system failed somewhere. Singh held valid CDLs from both California and Washington. He was not a U.S. citizen or legal permanent resident. Fox News reported that he was unable to read English road signs. Three people died in the resulting crash on a Florida highway.

Florida framed its claims under two legal theories: federal preemption, the argument that federal CDL standards override any conflicting state practice, and public nuisance, the argument that the licensing policies create a danger that crosses state lines.

The Court's recent willingness to weigh in on other contentious regulatory disputes makes its silence here all the more conspicuous. When the question involves abortion access or redistricting, the justices find a way to engage. When the question involves whether illegal immigrants can legally drive 80,000-pound trucks across state lines, the Court passes.

What the refusal means, and what it doesn't

The Court's refusal to hear the case is not a ruling on the merits. It does not mean the justices agreed with California and Washington. It means only that the majority decided not to exercise jurisdiction.

But as Thomas pointed out, the practical effect is the same as a loss for Florida. There is no other court that can hear the case. The dispute is effectively dead unless the Court reverses course or Congress acts.

That leaves a gap. Federal law says one thing. Two states appear to be doing another. A man who could not read English road signs held two valid commercial licenses and drove an 80,000-pound vehicle into a crash that killed three people. And the one court with the authority to resolve the dispute between the states involved chose not to.

The future composition of the Court may eventually shift the calculus on cases like this. But for now, the two justices most willing to enforce the constitutional framework for inter-state disputes were outnumbered.

Meanwhile, the families of the three people killed in that Florida crash have no Supreme Court ruling to point to. California and Washington face no judicial accountability for their licensing practices. And commercial trucks driven by people who may not meet federal standards continue to roll across state lines.

Washington state warned the Court not to open a door. The Court obliged. But the door that stays open, the one that lets states ignore federal licensing rules with no legal consequence, is the one that should worry everyone who shares a highway with an 80,000-pound truck.

The dynamics inside the Court remain a subject of intense public interest. This case will not make the front pages the way a gun case or an abortion case would. But the principle Thomas raised, that the Constitution requires the Court to hear disputes between states, full stop, is not a small one. It goes to the foundation of how the Union is supposed to work.

When the only court that can hear a case refuses to hear it, the Constitution doesn't have a backup plan. And neither do the people on the road.
