Activists gathered outside the Supreme Court on a frigid January morning to advocate for one the most consequential legal doctrines that you’ve probably never heard of.
Participants, representing groups supporting everything from environmental policy to the rights of the disabled, braved the wind and snow-lined sidewalks of Capitol Hill to urge the justices to uphold the 40-year-old practice of courts deferring to federal agencies when they create regulations that reasonably interpret federal law.
The so-called Chevron doctrine has been used scores of times to justify agencies' decisions to fight pollution, protect workers’ rights and provide Americans with affordable access to health care. It has also been used to bolster conservative causes, most recently during Donald Trump’s presidency to roll back Obama-era environmental rules the Republican administration felt were overly restrictive.
Later that morning, the Supreme Court heard arguments in two cases that challenge the Chevron doctrine and the authority federal agencies have gained through it. The court, which is dominated by Republican-backed justices, can shift the balance of power from the president to the judicial branch.
The cases – Loper Bright Enterprises v. Raimondo and Relentless Inc. v. Department of Commerce – both focus on Atlantic herring fisheries, which are regulated by the National Marine Fisheries Service. Under the Magnuson-Stevens Act, the agency required herring fishermen to pay for a mandatory at-sea monitoring program. Loper Bright and Relentless both sued, arguing that the fisheries service stretched the law beyond its original intention.
The demonstrators outside the Supreme Court said agencies’ interpretations of countless laws that protect people and nature are at risk in the case. Several protesters waved signs that read, “Stop the relentless power grab.” Across the way, a smaller group advocating for the court to strike down the doctrine stood silently. A few held signs saying, “It's time to stand up for the little guy.”
Erin Jackson-Hill, executive director for Stand Up Alaska, a nonprofit dedicated to increasing civic engagement, addressed the crowd.
“It is imperative that we remain vigilant and steadfast in our defense of this doctrine, as it plays a pivotal role in maintaining the balance of power and preserving the integrity of our legal system,” she said.
One demonstrator commented that she had never heard of the legal doctrine before the case went to the Supreme Court but now understands how important it has been.
The Chevron doctrine comes from the 1984 case Chevron U.S.A. Inc. v. Natural Resource Defense Council, Inc. The Supreme Court ruled that courts would defer to federal agencies when statutes are ambiguous. Such rule-making, the court said, is only appropriate when the agency’s interpretation is reasonable and Congress had not spoken directly on the issue.
In practice, Chevron allowed the Environmental Protection Agency to use the Clean Air Act, which had not seen any major changes since 1990, to propose stronger passenger vehicle emissions standards, including as recently as last year.
Chevron also allowed the Department of Housing and Urban Development leeway to implement the Fair Housing Act, which protects people from discrimination when renting or buying a home, or seeking a mortgage. Under Chevron, the department was able to set rules for how landlords and banks avoid discrimination.
If the justices overrule Chevron, they would give the courts much more power to challenge and direct the way that agencies implement policy, according to Devon Ombres, a senior director for the Center for American Progress, a liberal think tank.
In total, according to some experts, federal appellate courts have cited Chevron more than 5,000 times. Ombres predicts that if it gets overturned, industries would overwhelm federal courts with challenges to regulations.
The Supreme Court’s three liberal members underscored the importance of Chevron, saying it allows agencies to govern when the law “runs out,” as Justice Elena Kagan put it.
Kagan explained that members of Congress create laws knowing that there will be gaps in their knowledge as well as future advances. She used the example of Congress attempting to make laws regulating AI.
“Congress knows that this court and the lower courts are not competent with respect to deciding all the questions about AI that are going to come up in the future. And what Congress wants, we presume, is for people that actually know about AI to decide those questions,” she said.
She also peppered the attorney for Relentless, Roman Martinez, with hypothetical questions that could face courts if Chevron were to be overturned.
“Is a new product designed to promote healthy cholesterol levels a dietary supplement or a drug?” Kagan asked the attorney.
Martinez said it would depend on the “original understanding of the text of that statue read in context” and he would not directly answer the question.
The six conservative justices seemed to agree that, under Chevron, courts have been too deferential to federal agencies. (The Supreme Court has noticeably ignored citing the doctrine in cases where it would be relevant during recent oral arguments.) They discussed the consequences of rejecting or narrowing Chevron.
Justice Brett Kavanaugh criticized Chevron by pointing out that judges have no control over agencies ability to “flip-flop” their interpretations of laws passed by Congress.
“Chevron itself ushers in shocks to the system every four or eight years when a new administration comes in,” he said.
Chief Justice John Roberts and Justice Neil Gorsuch suggested that a better model would be the ruling in Skidmore v. Swift & Co., which allowed a federal court to determine the appropriate level of deference. But Kavanaugh was skeptical of the deference courts could give federal agencies under Skidmore.
It was unclear how the court would move forward, but it seems unlikely to both defenders and opponents of Chevron that the doctrine will continue to have the same sway over U.S. policy that it has had for 40 years. The likely outcome will shift power away from the executive branch and give more to Congress and the courts.
“The least likely thing to happen is for the court to just leave Chevron as it is,” said Adi Dynar, an attorney and separation of powers expert for Pacific Legal Group.

Trump is stuck between two realities. Neither serves the American people
Normally, I worry that events may overtake a column. But not so with the Iran war.
I don’t worry about running afoul of a headline or Truth Social post from the president because what is said about the situation is no longer very relevant to the reality.
On April 8, Nick Catoggio, my Dispatch colleague, dubbed an earlier stoppage with Iran “Schrödinger’s ceasefire.” This was a reference to the famous thought experiment by the physicist Erwin Schrödinger, who was trying to explain the weirdness of “superpositionality” in quantum physics. A cat in a box is both dead and alive at the same time until you open the box. Schrödinger meant to illustrate the absurdity of the idea that particles aren’t any one thing, but a “cloud of probabilities.”
The Trump administration is stuck in a word cloud of probabilities of his own making. The war is over. The war is on. The war isn’t a war. We have a deal, but we don’t have a deal, but we’re about to have a deal. We destroyed Iran’s military. No, we left it intact. We want regime change. No we don’t. We already accomplished it. We “obliterated” Iran’s nuclear program a year ago. We had to go to war in February to prevent nuclear war. The Strait of Hormuz is open, closed, or something in-between. No deal without “unconditional surrender.” Let’s make a deal!
This everything-all-at-once vibe can be disorienting, particularly since most Americans didn’t have a war with Iran on their bingo cards until the shooting had already started. President Trump didn’t prepare the country or consult with Congress beforehand because he thought it would all be a smashing success in a matter of weeks.
The miscalculation that started it all: killing Iran’s Supreme Leader, Ayatollah Ali Khamenei, and much of Iran’s senior leadership, on the first day of the war. To “the great proud people of Iran, I say tonight that the hour of your freedom is at hand,” Trump announced on Feb. 28. “When we are finished, take over your government. It will be yours to take. This will be probably your only chance for generations.”
I support regime change in Iran and shed no tears for Khamenei or his goons. But when you start a war by killing the regime’s top leaders, it’s not unreasonable for the remaining ones to conclude that you really intend regime change.
Khamenei was a murderous fanatic, but he was a fairly cautious one. He liked to threaten closing the Strait of Hormuz or attacking our regional allies, but he was reluctant to actually do it, fearing it would invite a regime change war. The mullahs and IRGC goons believed, not unreasonably, that if they lost their grip on power, they’d be lynched by the Iranian people they’ve brutalized for decades.
By starting with a regime change war, Trump removed any reason for the regime not to go for broke. When you have nothing to lose — particularly when you are a millenarian religious fanatic — a Persian Alamo strategy makes a lot of sense.
So Iran closed the Strait of Hormuz and attacked its neighbors.
But it turns out this wasn’t the Alamo. In the contest of wills, Trump blinked. The Iranian regime’s tolerance for punishment proved — so far — to be greater than Trump’s and that of our gulf allies. Militarily we could finish the job, but that would require ground troops and much greater economic turmoil. In a conflict Trump launched unilaterally without the prior support of Congress, NATO or the American people, Trump doesn’t have the political capital for that.
But that’s only half the problem. Trump wants the war over, but he doesn’t want to pay — militarily, economically, politically — what that would cost. So he wants to make a deal that ends it. But there is no deal available that wouldn’t come at an equally undesirable cost. Any deal that looks like what President Obama struck with the Iranians would be too embarrassing to bear. But the Iranians are convinced that they can get just such a deal, and they’re willing to drag things out as long as it takes.
The result: Trump’s in a box of his own making. He thinks he can talk his way out by simply asserting a reality that doesn’t exist. When the financial markets get nervous, he announces a breakthrough that is, at best, a possibility. When the Iranians agree to a deal that looks similar to one Obama might negotiate, Trump goes back to his threats.
It can’t go on forever. But I’m sure it’ll last until long after this column is forgotten.
