What Did the Supreme Court Actually Change When It Overruled Chevron?
The Supreme Court's June 2024 decisions in Loper Bright Enterprises v. Raimondo and Relentless Inc. v. Department of Commerce eliminated the doctrine that required federal courts to defer to administrative agencies when statutes were silent or ambiguous, and Article III judges must now exercise independent judgment in interpreting federal law, just as Chief Justice Roberts explained in the majority opinion. That change reverses a 40-year arrangement rooted in Chevron U.S.A. Inc. v. Natural Resources Defense Council, 467 U.S. 837 (1984), which handed agencies a systematic advantage every time a regulatory text reached the courthouse.
The doctrine never appeared in the Constitution, in any statute, or in the original design of separated powers. It grew instead from a two-step interpretive framework that the Court itself announced and then expanded across thousands of agency decisions. By 2024, Chevron had been cited in more than 18,000 federal judicial opinions, according to legal research databases, which gives some measure of how thoroughly it had reshaped the relationship between courts, Congress, and the executive branch. Lower courts treated it as a shortcut. Agencies treated it as a shield. Litigants treated it as a reason not to bring challenges at all.
Loper Bright does not strip agencies of all power to fill gaps or apply technical expertise. It restores the judicial duty to say what the law is, a duty that predates the Republic and that the Framers placed in Article III precisely to prevent arbitrary rule. Justice Thomas made the point in concurrence: deference to agencies violated the separation of powers by transferring judicial power to the executive. Justice Gorsuch, also concurring, emphasized that Chevron had especially harmed ordinary Americans who could not predict how an agency would rewrite the law from one administration to the next. That instability is not a feature of lawful government.
Why Does Returning Interpretive Power to Courts Matter for Self-Government?
Returning interpretive power to courts matters because it restores the constitutional structure that forces Congress to write precise statutes instead of delegating lawmaking to unelected agencies. When judges deferred to agency readings of law, lawmakers could pass vague bills, let agencies write the details, and then blame bureaucrats when the resulting rules angered voters. That process produced the modern regulatory state, which includes roughly 185,000 pages in the Code of Federal Regulations and annual Federal Register output that routinely exceeds 80,000 pages.
The Competitive Enterprise Institute has estimated that federal regulations now impose compliance costs approaching $2 trillion each year, a burden that falls heaviest on small businesses and on households through higher prices. Those numbers are not the fault of Chevron alone. But Chevron made the problem harder to fix by letting agencies defend almost any reading of an ambiguous statute so long as it was reasonable. After Loper Bright, a statute that fails to authorize a regulation means the regulation fails in court. That is how a written constitution is supposed to work. Congress must make the hard choices, agencies must execute them faithfully, and judges must resolve disputes about meaning.
The Congressional Research Service has documented that Congress passes far fewer statutes today than it did in prior decades while federal agencies issue thousands of rules annually. That imbalance should worry anyone who believes law should be made by elected representatives. It should also worry anyone who values stability. A rule issued by one agency under one president can be revised or revoked by the next, creating whiplash for regulated industries and for citizens trying to plan their lives. Returning interpretive authority to courts does not eliminate agency discretion in technical matters. It simply requires that the legal meaning of a statute be decided by judges, not by the same officials who stand to benefit from a broad reading.
What Should Conservatives Expect From a Post-Chevron Judiciary?
Conservatives should expect neither automatic victories nor automatic deregulation, but they should expect a more honest allocation of authority between Congress, agencies, and the courts. The Roberts Court has shown it will enforce statutory text even when the policy result displeases one faction or another, and Loper Bright applies that discipline to the administrative state. In Loper Bright, the majority refused to preserve Chevron merely because agencies and lower courts had grown comfortable with it. That kind of institutional honesty is rare in Washington. It also imposes responsibility on Congress.
Republicans who now cheer the end of Chevron will have to write statutes that actually say what they mean, not hand vague instructions to friendly regulators. Democrats will have to do the same when they hold power. The alternative is continued drift toward rule by regulation, in which 2.2 million federal civilian employees and hundreds of independent agencies make most of the rules that govern daily life. The Alamo Post was founded this year to insist that constitutional structure is not an abstraction. Loper Bright proves the point.
The conservative legal movement spent decades arguing that original meaning and textual clarity should constrain both judges and agencies. Loper Bright is the payoff, but it is only a beginning. Lower courts will now decide thousands of cases without the crutch of Chevron deference. Some will get the text right. Some will not. The task for commentators, litigators, and legislators is to hold them to the standard the Supreme Court has announced. The Constitution still contains the tools to limit power, if judges and legislators have the courage to use them. After June 2024, they have fewer excuses for failing.
