The Supreme Court’s quiet coup

The Roberts Supreme Court is increasingly perceived as systematically eroding the legislative authority of the U.S. Congress through a series of jurisprudential shifts. This "quiet coup" is characterized by the Court's reassertion of judicial power in statutory interpretation, notably through the formalization and expansion of the Major Questions Doctrine and the recent overturning of *Chevron* deference. These developments significantly narrow Congress's ability to delegate authority to administrative agencies and shape the implementation of its enacted laws. The Court's actions, while often framed as upholding the separation of powers, are effectively reallocating policy-making influence from the democratically elected legislative branch to the unelected judiciary, with profound implications for federal governance and the administrative state.

In recent years, a growing chorus of legal observers has pointed to a significant, albeit subtle, shift in the balance of power within the U.S. federal government. This shift, often described as a "quiet coup," sees the Supreme Court, under Chief Justice John Roberts, systematically diminishing the legislative authority of Congress. The Court's actions are not typically found in its high-profile, politically charged decisions concerning issues like reproductive rights or firearms, but rather in less conspicuous rulings that fundamentally alter how laws are interpreted, implemented, and defended.

This erosion of congressional power is not accidental; it is the direct result of calculated intrusions into Congress's constitutionally designated role to write laws, allocate funding, and set federal policy. The Court has radically narrowed Congress's ability to shape the post-enactment life of legislation, impacting the administrative state and the efficacy of federal policy. This article will explore the mechanisms through which the Roberts Court has achieved this rebalancing, focusing on key doctrines and recent landmark decisions that underscore this profound transformation in American governance.

The U.S. Constitution establishes a system of separated powers, vesting legislative power in Congress (Article I), executive power in the President (Article II), and judicial power in the Supreme Court and lower federal courts (Article III). Article I, Section 8 enumerates Congress's powers, including the authority to make all laws "necessary and proper" for carrying into execution its enumerated powers. Traditionally, Congress has delegated significant authority to executive branch agencies to implement complex statutory schemes, relying on agency expertise. This practice was largely accommodated by judicial deference doctrines.

Central to the administrative state for decades was the principle of *Chevron* deference, established in *Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc.*, 467 U.S. 837 (1984). Under *Chevron*, courts generally deferred to a federal agency's reasonable interpretation of an ambiguous statute that it was charged with administering. This deference acknowledged that agencies often possess specialized expertise and are more politically accountable than courts for policy choices within statutory bounds. Another related doctrine, the nondelegation doctrine, holds that Congress cannot delegate its strictly legislative powers without providing an "intelligible principle" to guide the executive branch. While frequently challenged, this doctrine has rarely been successfully invoked to strike down federal statutes since 1935.

The Roberts Court has significantly recalibrated the balance of power, primarily through the expansion of the Major Questions Doctrine (MQD) and the recent overturning of *Chevron* deference. The MQD, formally invoked in *West Virginia v. Environmental Protection Agency*, 597 U.S. 697 (2022), requires clear congressional authorization for agencies to regulate on matters of "vast economic and political significance." This doctrine operates as a "clear statement rule," effectively shifting the burden to Congress to explicitly grant authority for major policy decisions, rather than allowing agencies to interpret broad statutory mandates. The Court applied the MQD to invalidate the EPA's Clean Power Plan, arguing that the agency exceeded its authority under the Clean Air Act without clear congressional direction for such a significant "generation shifting" policy.

Further demonstrating this trend, the Court utilized the MQD in *Alabama Association of Realtors v. Department of Health and Human Services*, 594 U.S. 637 (2021), to block the Centers for Disease Control and Prevention's (CDC) eviction moratorium, finding that the Public Health Service Act did not clearly authorize such a sweeping measure. Similarly, in *Biden v. Nebraska*, 599 U.S. ___ (2023), the Court relied on the MQD to strike down the Department of Education's student loan forgiveness program, concluding that the HEROES Act did not provide clear authorization for a program of such "economic and political significance." These decisions illustrate a judicial skepticism towards broad agency interpretations, compelling Congress to be far more prescriptive in its legislative language if it intends for agencies to address significant policy issues.

Perhaps the most impactful development is the Supreme Court's decision in *Loper Bright Enterprises, Inc. v. Raimondo*, 602 U.S. ___ (2024), which explicitly overruled *Chevron* deference. This landmark ruling eliminates the long-standing practice of judicial deference to agency interpretations of ambiguous statutes, asserting that it is the judiciary's role to "say what the law is." The overturning of *Chevron* fundamentally alters the landscape of administrative law, transferring significant interpretive power from expert agencies to federal courts. While proponents argue this restores judicial independence and limits the "administrative state," critics contend it injects greater judicial policy-making into areas where agencies possess superior technical knowledge and democratic accountability.

Beyond statutory interpretation, the Court has also influenced Congress's ability to structure the executive branch. In *Trump v. Slaughter*, 602 U.S. ___ (2026), the Court overturned *Humphrey's Executor v. United States*, 295 U.S. 602 (1935), expanding the President's power to remove heads of independent agencies. This decision curtails Congress's ability to insulate certain agencies from direct presidential control, thereby impacting the independence and policy-making capacity of bodies designed to operate outside immediate political pressures. While the nondelegation doctrine itself has not seen a full "revolution" (as evidenced by *FCC v. Consumers' Research*, 605 U.S. ___ (2025), which upheld a delegation), the combined effect of the MQD and the demise of *Chevron* achieves many of the same goals of constraining administrative power through subtler means.

The Roberts Court's jurisprudence marks a significant reordering of the separation of powers, quietly but profoundly shifting influence from the legislative branch to the judiciary. For practicing attorneys, this landscape necessitates a heightened awareness of statutory clarity and congressional intent. Litigators challenging agency actions will find new avenues under the Major Questions Doctrine and the absence of *Chevron* deference, requiring agencies to demonstrate explicit congressional authorization for significant policy initiatives. Conversely, those defending agency actions will face a more skeptical judiciary, demanding robust textual and structural arguments for delegated authority.

Looking ahead, Congress faces a critical challenge to reassert its legislative prerogatives. If the Court demands clear statements for major policy decisions, Congress must respond with more precise and detailed legislation, or risk seeing its broad mandates curtailed by judicial review. The long-term implications include potentially slower, more cumbersome legislative processes and a judiciary increasingly involved in policy determinations previously left to the executive branch. Practitioners should closely monitor how federal agencies adapt their rulemaking processes and how Congress responds to these judicial mandates, as the balance of power continues to evolve in the American legal system.
