The Chevron Deference and Its Demise: A Significant Shift in U.S. Administrative Law

The Supreme Court, in a 6-3 vote, recently overturned a longstanding legal precedent known as the “Chevron deference.” This landmark decision has far-reaching implications for the powers of federal agencies, marking a pivotal moment in U.S. administrative law. Justice Neil Gorsuch, one of the court’s most conservative members, remarked, “Today, the court places a tombstone on Chevron no one can miss.” This article delves into the history of the Chevron deference, its significance, and the consequences of its elimination.

Understanding Chevron Deference

The term “Chevron deference” originates from the 1984 Supreme Court case Chevron U.S.A., Inc. v. Natural Resources Defense Council, Inc. In this case, the court ruled that federal judges should defer to agency interpretations of ambiguous statutes, provided those interpretations are reasonable. This decision was grounded in the belief that agencies possess the expertise needed to make informed decisions on complex regulatory matters, while courts do not. Essentially, if Congress passed a law with unclear provisions, it was up to the relevant federal agency to interpret and implement those provisions.

This deference granted agencies like the Environmental Protection Agency (EPA) considerable leeway in crafting and enforcing regulations. The underlying rationale was that agencies, staffed with subject matter experts, were better equipped than courts to handle technical and specialized issues. For decades, this principle allowed agencies to operate with a significant degree of autonomy, making rules without the constant threat of legal challenges undermining their authority.

The Case That Ended Chevron Deference

The downfall of Chevron deference can be traced to a 2020 case involving herring fishermen. The Trump administration had introduced a requirement for fishermen to cover the costs of federal monitors on their vessels. These monitors were tasked with overseeing the Atlantic fishery, a region extending from Maine to North Carolina. Prior to this mandate, the costs of these monitors were not borne by the fishermen. Commercial fishing companies, backed by conservative and corporate groups including billionaire Charles Koch, challenged this requirement in court.

In one case, a federal judge upheld the National Marine Fisheries Service’s authority to impose these costs, citing Chevron deference. This decision underscored the power federal agencies had under the Chevron framework to interpret and implement regulations even when statutes were ambiguous.

The Impact of Overturning Chevron Deference

The Supreme Court’s decision to overturn Chevron deference is a significant victory for conservatives who have long sought to limit the power of federal agencies. For nearly four decades, Chevron deference had expanded the reach of the federal bureaucracy, allowing agencies to interpret laws in ways that often extended their regulatory authority. By eliminating this principle, the Supreme Court has curtailed the autonomy of agencies, requiring them to operate under more explicit directives from Congress.

Winners and Losers


  1. Conservatives and Corporate Interests: The elimination of Chevron deference is a major win for conservatives who have argued that the principle gave too much power to unelected bureaucrats. Corporate interests, which often chafed under extensive regulations, also stand to benefit. The decision reduces the ability of agencies to unilaterally impose rules that can have significant financial and operational impacts on businesses.
  2. The Judiciary: With Chevron deference gone, courts will have a greater role in interpreting statutes. This shift increases judicial oversight of agency actions, potentially leading to more consistent and predictable interpretations of laws.


  1. The Biden Administration: The ruling is a setback for the current administration, which had argued that eliminating Chevron deference would lead to regulatory instability. The administration’s ability to implement its policy agenda through agency rulemaking is now significantly constrained.
  2. Advocacy Groups and Progressives: Organizations advocating for environmental protection, public health, and worker safety view the decision as a loss. Without Chevron deference, it will be harder for agencies like the EPA to implement regulations aimed at safeguarding these interests.
  3. The General Public: Groups like the Asbestos Disease Awareness Organisation have voiced concerns that the ruling undermines critical protections. The decision could lead to weaker enforcement of regulations that ensure clean water, fair lending practices, and workplace safety.

The Road Ahead

The Supreme Court’s decision does not retroactively apply to past agency regulations but will shape future regulatory actions. Corporations and other entities are likely to challenge agency rules more frequently, leading to increased judicial involvement in regulatory matters. This could result in a patchwork of rulings as different judges interpret agency powers in varied ways.

Looking forward, Congress will need to provide more explicit instructions in its legislation to guide agency actions. However, given the current political climate, passing detailed and clear legislation may prove challenging. Philip Bobbitt, a constitutional law expert at Columbia Law School, noted, “Where the court is going… seems to defy the realities of gridlock in the Congress as it’s actually operating today.”


The demise of Chevron deference marks a monumental shift in the balance of power between federal agencies and the judiciary. By removing the deference previously afforded to agency interpretations, the Supreme Court has reined in the administrative state, aligning with a longstanding conservative goal. While this decision empowers the judiciary and potentially benefits businesses, it also introduces new challenges for regulatory enforcement and legislative clarity. The full impact of this ruling will unfold over time as courts, agencies, and Congress navigate this transformed legal landscape.
