Seeking Proportionality in Administrative Law

Key Takeaways

• Proportionality links agency procedure to regulatory importance
• Supreme Court’s major‑questions doctrine demands clear congressional authority
• Biden’s OIRA raised review threshold to $200 million impact
• Congress must codify proportionality to cement the principle
• Tiered rulemaking aims to de‑proceduralize minor agency actions

Pulse Analysis

Proportionality is emerging as a unifying theme in U.S. administrative law, offering a framework that aligns the depth of procedural safeguards with the weight of regulatory decisions. By tying Congress’s involvement, agency rulemaking rigor, and judicial scrutiny to the economic and political significance of an action, the approach promises a more efficient allocation of governmental resources. Recent Supreme Court rulings—most notably the major‑questions doctrine and the limitation on injunctive relief in Trump v. CASA—signal judicial willingness to demand explicit congressional authorization for high‑impact rules, reinforcing the proportionality narrative.

The executive branch has already begun to operationalize this principle. Under the Trump administration, the Department of Transportation reserved formal rulemaking for its most consequential regulations, while the Biden administration’s Office of Information and Regulatory Affairs (OIRA) doubled the economic impact threshold for centralized review to $200 million. These internal reforms illustrate how agencies can self‑regulate, reducing procedural burdens for routine matters while reserving intensive scrutiny for rules that reshape markets or public policy. Such tiered processes not only cut compliance costs but also mitigate the risk of costly litigation stemming from over‑reach.

For proportionality to become entrenched, Congress must act. Legislative codification would provide clear standards for when detailed procedural requirements and heightened judicial review are warranted, preventing ad‑hoc interpretations that could undermine consistency. By embedding proportionality into statutes, lawmakers can ensure that major regulatory choices remain subject to democratic oversight, while allowing agencies the flexibility to fine‑tune less consequential details. This balanced architecture could restore public confidence in regulatory governance and foster a more predictable business environment.
