Another big Supreme Court decision this week landed squarely on immigration — Mullin v. Al Otro Lado — and it brought into sharper focus a running debate about how one justice chooses to air her disagreements. The court’s majority ruled for the government on whether migrants who stay on the Mexican side of the border “arrive in the United States” for asylum purposes. The case also prompted fresh commentary about Justice Ketanji Brown Jackson’s style of dissenting, but the record matters: the Mullin dissent was authored by Associate Justice Sonia Sotomayor and joined by Associate Justices Elena Kagan and Ketanji Brown Jackson, not a solo Jackson disagreement.
The actual ruling and what it means
The Supreme Court in Mullin sided with the government and limited a route some migrants have tried to use to claim asylum without physically entering the United States. That is the immediate, practical result: tighter legal footing for immigration enforcement at the border. Critics on the left will call it harsh and critics on the right may call it overdue. Either way, this ruling shifts how lower courts and agencies will treat asylum claims made from just across the border.
Why critics keep circling Justice Jackson
Commentary about Justice Ketanji Brown Jackson isn’t entirely invented. She has written pointed lone dissents in other cases this term and has at times read or emphasized her views publicly. Those solo dissents — like her lone vote in Chiles v. Salazar — have drawn sharp pushback from colleagues and conservatives alike. But accuracy matters. In Mullin she did not author a solo dissent; she joined one. Still, the pattern people complain about is real: a justice who publishes strong, theatrical dissents and who has defended airing those views in public settings.
Court packing and the “more KBJs” worry
That pattern feeds a larger political fear: Democrats talk openly about adding justices, and conservatives worry what would happen if the Court were expanded with more jurists who embrace the same activist stance. Call it the “one KBJ is messy enough” argument. A Supreme Court stacked to create majorities for sweeping policy rewrites would not just change outcomes — it would change how Americans see the law. If dissents become blueprints for future partisan lawmaking rather than reasoned legal disagreement, the Court’s legitimacy takes a hit.
Justice Jackson is entitled to her views. The question for conservatives is whether those views belong on the Supreme Court if they amount to repeated solo shows that sidestep coalition-building and established restraint. Mullin reminds us that the decisions matter on the ground; the dissents matter for the vibe and future fights. Keep watching the opinions, and keep insisting on accuracy when critics make claims — facts still matter, even when the political theater gets loud.
