Supreme Court Justice Sonia Sotomayor used a public appearance at the University of Kansas School of Law on Tuesday to take a personal shot at fellow Justice Brett Kavanaugh, suggesting his upbringing as the son of professionals disqualifies him from understanding the impact of immigration enforcement on hourly workers. The remarks, first reported by the New York Post, revived a dispute rooted in Kavanaugh's concurring opinion last September that allowed the Trump administration to continue ICE raids in the Los Angeles area.
Sotomayor did not name Kavanaugh directly in her remarks but left no doubt about her target. She referred to "a colleague in that case" who characterized immigration stops as temporary, then pivoted to a class-based critique of his life experience.
The episode raises a straightforward question: Should a sitting Supreme Court justice publicly argue that a colleague's legal reasoning is invalid because of where he grew up?
Bloomberg Law reported that Sotomayor argued even short detentions could financially harm people, especially hourly workers. At the Kansas event, she framed Kavanaugh's concurrence as the product of personal ignorance rather than legal analysis. She told the audience:
"I had a colleague in that case who wrote, you know, these are only temporary stops. This is from a man whose parents were professionals. And probably doesn't really know any person who works by the hour."
She continued by describing the real-world stakes for workers detained during ICE operations:
"Those hours that they took you away, nobody's paying that person. And that makes a difference between a meal for him and his kids that night and maybe just cold supper."
The argument has a surface appeal. Nobody disputes that lost wages hurt working families. But Sotomayor was not making a narrow policy point. She was telling a law school audience that her colleague's legal position flows from personal privilege, not from the law, not from precedent, not from the Constitution. That is a remarkable claim for one justice to level at another in a public forum.
Kavanaugh's concurring opinion, issued last September, did not dismiss the hardship of immigration enforcement. It addressed the legal framework for stops based on reasonable suspicion of unlawful presence. In that opinion, he wrote:
"Immigration stops based on reasonable suspicion of illegal presence have been an important component of US immigration enforcement for decades, across several presidential administrations."
He also argued that any stops were "typically brief" and that most migrants "promptly go free." Whether one agrees with that characterization or not, it is a legal argument grounded in enforcement history. It is not a confession of class blindness.
The Supreme Court has long grappled with the tension between effective immigration enforcement and individual rights. Those debates have historically been conducted on legal terms, through written opinions, not through public speculation about a colleague's childhood. The ideological divisions on the current Court are well documented, but the norms that govern how justices discuss one another's reasoning still matter.
Sotomayor and the Court's two other liberal justices issued a dissent at the time of the ruling. That dissent went further than her Kansas remarks, charging that the government's enforcement approach amounted to ethnic profiling.
"We should not have to live in a country where the government can seize anyone who looks Latino, speaks Spanish, and appears to work a low wage job."
The dissent described the Trump administration's sweeping immigration raids in the Los Angeles area last year and argued the raids targeted individuals based on broad criteria, including their occupation or whether they speak Spanish. Those are serious allegations, but they belong in a legal opinion, where they can be tested against the record, not in a campus speech where they go unchallenged.
The broader fight over who sits on the Supreme Court and how justices conduct themselves has intensified in recent years. Some Democrats have poured millions into campaigns to block conservative nominees, treating the Court less as an institution and more as a political prize. Sotomayor's willingness to personalize a legal disagreement fits that pattern.
Strip away the emotional framing and Sotomayor's argument reduces to this: Kavanaugh's parents were professionals, so he cannot understand working people, so his legal analysis on immigration stops is wrong. That chain of reasoning would not survive a first-year logic class, let alone the standard a Supreme Court justice should meet.
If personal background determines the validity of legal reasoning, then every justice's opinions are open to the same attack. Sotomayor herself has spoken extensively about how her upbringing in the Bronx shaped her worldview. That biography is admirable. But she has never accepted the premise that her background should be used to dismiss her legal conclusions, and she should not apply that standard to Kavanaugh.
The implication is also factually shaky. Sotomayor said Kavanaugh "probably doesn't really know any person who works by the hour." That is speculation, not evidence. It is the kind of assumption that, if directed at a liberal justice, would be called prejudice.
Tensions on the Court have spilled into public view before. Even presidents have openly criticized justices they appointed when rulings go against them. But there is a difference between outside political pressure and an inside campaign to delegitimize a colleague's reasoning based on his family tree.
Sotomayor's Kansas appearance is not the first time she has used extrajudicial settings to advance arguments that go beyond the four corners of an opinion. The liberal wing of the Court has grown more vocal in recent terms, both in dissents and in public remarks. The question is whether that trend serves the institution or erodes it.
The answer matters because public trust in the Court depends on the perception that justices decide cases on the law, not on personal grudges, class resentments, or identity politics. When a justice tells a room full of law students that a colleague's opinion is really just the product of a privileged upbringing, she is not strengthening the Court. She is borrowing the language of campus activism and importing it into the one branch of government that is supposed to stand above it.
Control of state and federal courts has become one of the most contested battlegrounds in American politics. Voters in Wisconsin recently handed liberals a locked-in majority on that state's supreme court through 2030, underscoring how much both sides now treat judicial seats as political assets. That makes it all the more important for sitting justices to model the kind of dispassionate reasoning the public expects.
The Court has also continued to hand down consequential rulings on cultural and constitutional questions, including a recent 6-3 decision striking down California's transgender secrecy law in favor of parental rights. In every one of these cases, the legitimacy of the outcome depends on the public's belief that justices are reasoning from law, not from autobiography.
Kavanaugh wrote a legal opinion rooted in decades of enforcement precedent. Sotomayor responded, months later, in a law school auditorium, by questioning his life experience. One of those approaches belongs on the Supreme Court. The other belongs on a cable news panel.
The ICE raids in Los Angeles raise legitimate questions about enforcement tactics, civil liberties, and the treatment of workers caught up in operations. Those questions deserve serious legal debate. They do not deserve to be reduced to a talking point about one justice's parents.
If the measure of a legal argument is the biography of the person making it, then the Court has no standard at all, just a credentialing contest dressed up in robes.
