The administrative agency cases were not the court’s only significant separation of powers decisions this term

# Supreme Court Signals Broad Skepticism Toward Agency Power in Separation of Doctrine

The Supreme Court delivered multiple separation of powers rulings this term that extend beyond administrative law, signaling deeper constitutional concerns about executive branch authority and judicial deference frameworks.

The Court's decisions challenged the longstanding Chevron deference doctrine, which required courts to defer to agency interpretations of ambiguous statutes. In striking down this framework, the justices rejected the notion that Congress implicitly delegated interpretive authority to executive agencies. This represents a fundamental shift in how federal courts will review regulatory action going forward.

Beyond Chevron, the Court addressed additional separation of powers questions affecting agency power. These rulings addressed the scope of the Take Care Clause, which requires the President to faithfully execute laws passed by Congress. The decisions constrain executive discretion in implementing statutes and reinforce that agencies cannot exercise powers Congress did not explicitly grant them.

The Court also examined the constitutionality of certain agency structures, particularly independent agencies insulated from presidential removal. While stopping short of overturning the Humphrey's Executor precedent entirely, the justices tightened restrictions on how Congress can shield agency officials from executive control, strengthening presidential power over subordinates.

Collectively, these rulings reflect the current Court majority's commitment to restoring what it views as the proper constitutional balance between branches. The decisions prioritize legislative clarity and presidential accountability over administrative efficiency and expertise-based lawmaking.

The practical impact extends across industries. Regulated entities can now challenge agency interpretations more successfully in court. Environmental regulations, labor rules, healthcare policy, and financial oversight face heightened vulnerability to legal challenge. Agencies must point to explicit statutory language rather than reasonable interpretations to defend their actions.

For businesses, this creates both opportunity and uncertainty. Companies can mount stronger legal challenges to unfavorable rules. Yet regulatory ambiguity increases
