Justice Neil Gorsuch used the Supreme Court's landmark tariff decision not just to rule against President Trump's use of the International Emergency Economic Powers Act, but to settle scores across the ideological spectrum of his own bench.
His solo opinion stretched 46 pages, more than twice the length of the main opinion, and took aim at liberal justices, conservative dissenters, and even allies in between.
The Court invoked the major questions doctrine to reject the assertion that the 1977 IEEPA granted the president sweeping tariff authority, The Hill reported. That much was expected. What nobody expected was the accompanying judicial bloodbath.
William & Mary law professor Jonathan Adler described Gorsuch's camp-by-camp takedown as something of a "Godfather-esque settling of family business." That framing is hard to argue with.
Gorsuch didn't single out one faction. He went after all of them. The liberal justices, in his telling, refuse to recognize the major questions doctrine at all. Justice Elena Kagan has accused conservative colleagues of "magically" inventing it and on Friday referred to it as a "so-called" doctrine. Gorsuch clearly noticed. And Kagan, for her part, returned fire:
"Given how strong his apparent desire for converts, I almost regret to inform him that I am not one. But that is the fact of the matter."
Among the conservative dissenters, three wanted to carve out exceptions. Justices Kavanaugh and Alito argued the doctrine shouldn't apply to foreign affairs. Justice Thomas went further, suggesting in a solo dissent that Congress may "hand over" most of its powers, including tariff authority, to the president without limit. Gorsuch skewered that position directly:
"Suppose for argument's sake that Congress can delegate its tariff powers to the President as completely as Justice Thomas suggests. Even then, the question remains whether Congress has given the President the tariff authority he claims in this case — or whether the President is seeking to exploit questionable statutory language to aggrandize his own power."
Even Justice Amy Coney Barrett caught a stray. Gorsuch characterized her as seeking to "soften the blow" of the doctrine by recasting it as a commonsense principle. Barrett fired back, saying of Gorsuch's critique: "He takes down a straw man."
Conservative law professor Josh Blackman at the South Texas College of Law Houston offered a theory for why the decision took so long to arrive:
"What took so long? The Chief probably wrote his majority opinion before breakfast. … I think the reason for the delay has to be Justice Gorsuch."
Forty-six pages don't write themselves.
Strip away the intracourt drama, and something substantive emerges. Gorsuch is making a case for constitutional consistency. The major question doctrine holds that when an executive agency or the president claims sweeping new authority under an old statute, Congress must have spoken clearly. You don't get to reinterpret vague language in a half-century-old law to justify a power grab that Congress never explicitly authorized.
Gorsuch noted that only he and Chief Justice Roberts "have stayed the course" on the doctrine's application. He described the legislative process as a "bulwark of liberty" and its deliberative nature as the "whole point." The implication is clear: everyone else has treated the doctrine as a tool of convenience rather than a fixed principle.
"Whatever else might be said about Congress's work in IEEPA, it did not clearly surrender to the President the sweeping tariff power he seeks to wield."
This is the crux. Conservatives have championed the major questions doctrine for years as a check on executive overreach. The Court used it to:
Gorsuch's argument is straightforward: you don't get to love the doctrine when it restrains a Democratic president and then abandon it when it inconveniences your own side. Constitutional principles either apply across administrations or they aren't principles at all.
There is a rich irony in the left's sudden enthusiasm for a ruling grounded in a doctrine they have spent years trying to destroy. Sen. Sheldon Whitehouse took to the Senate floor in 2024 to attack it directly:
"There is enormous upheaval from that novel doctrine imported by the billionaire-selected justices of the Supreme Court into American law."
Now that the same doctrine blocks a Trump tariff, the left discovers its merits. This is the pattern. Constitutional guardrails are either dangerous "novel doctrines" or sacred protections, depending entirely on whose ox is being gored. Kagan still calls it "so-called." Whitehouse still thinks it was illegitimately invented. But they'll take the result, thank you very much.
Conservatives should recognize this dynamic for what it is. The left has no principled commitment to the major questions doctrine. They will resume attacking it the moment it next restrains a Democratic administration. Gorsuch, whatever his faults in alienating colleagues, is at least asking the right question: does this principle hold regardless of which party occupies the White House?
President Trump responded on social media over the weekend, announcing he would use lowercase letters when writing "supreme court" going forward, citing what he called a "complete lack of respect." He also said he would not need to work with Congress on tariffs going forward, stating simply: "I don't have to."
Scott Lincicome, vice president of general economics at the Cato Institute, expressed concern about that posture:
"I'm hoping that cooler heads prevail in the coming days, and the administration does make this as easy as possible, because if they don't, it will disproportionately burden small businesses that can't afford the lawyers and all the paperwork and the rest."
Victor Schwartz, who owns the wine importer VOS Selections and whose business led the challenge to the tariffs, offered a ground-level view of the stakes:
"These duties were not like past tariffs set by Congress, which we could plan around. Instead, these tariffs were arbitrary and simply put, just bad business. They forced us to gamble with our livelihoods by trying to predict the unpredictable."
The practical question now is whether the administration works with Congress to pass tariff legislation through proper channels or finds another legal mechanism. Andrew Morris, senior counsel at the New Civil Liberties Alliance who represents businesses challenging the tariffs, noted where the attention is focused: "The opinion of the court, what it says about the major questions doctrine, everyone has had their eyes on."
On Tuesday, the president will come face-to-face with the justices. The temperature in that room will tell its own story.
Gorsuch is not wrong on the law. The major questions doctrine is either a consistent constitutional safeguard or it is nothing. Conservatives who cheered when it dismantled Biden's student loan giveaway cannot credibly argue it should include a foreign-affairs exception or a "only applies to Democrats" carve-out.
But a 46-page opinion that manages to alienate every other justice on the bench, liberal and conservative alike, raises a different question. Being right and being effective are not always the same thing. Barrett says he's attacking a straw man. Kagan says she's unmoved. Thomas is dug in. That's a lot of bridges burned for a concurring opinion nobody was required to join.
Gorsuch called the result "better for it." The doctrine may be. The Court's internal cohesion is another matter. When every colleague on a nine-member bench finds something to object to in your writing, the problem may not be entirely with them.
Still, someone had to say it. If the major questions doctrine means anything, it means the same thing no matter who sits in the Oval Office. Gorsuch said it. Now the question is whether anyone was listening.
