Master Seminal administrative law case holding that agency action must be judged solely on the grounds the agency invoked at the time, not on post hoc rationalizations. with this comprehensive case brief.
SEC v. Chenery I is a cornerstone of administrative law that articulates a bedrock principle of judicial review: courts may uphold an administrative agency's action only on the reasons the agency actually gave when it acted. Known as the Chenery doctrine, this rule prevents courts and litigants from rescuing an otherwise deficient agency decision by inventing new rationales after the fact. The decision structures the relationship between agencies and reviewing courts, insisting on transparent, reasoned decisionmaking and preserving accountability to statutory mandates.
The dispute arose from an SEC reorganization proceeding under the Public Utility Holding Company Act of 1935, where corporate insiders had purchased preferred shares during the pendency of a reorganization plan. The SEC disapproved aspects of the plan based on general fiduciary principles. The Supreme Court held that the SEC's order could not be sustained on that legal theory and refused to ratify the order on alternative grounds that the government proposed only in litigation. Chenery I thus teaches two critical lessons: an agency's stated rationale must be legally sound and factually supported, and courts cannot supply missing reasons. The case's sequel, Chenery II, later clarified that agencies can develop policy through adjudication, but only if they clearly ground their decisions in that authority.
Securities and Exchange Commission v. Chenery Corp., 318 U.S. 80 (1943)
The Public Utility Holding Company Act of 1935 (PUHCA) empowered the Securities and Exchange Commission (SEC) to oversee the simplification and reorganization of complex utility holding companies through plans that must be "fair and equitable." During the reorganization of Federal Water Service Corporation (a public utility holding company), a group of its officers, directors, and controlling shareholders—associated with Chenery Corporation (the "Chenery group")—purchased preferred stock in the company while a reorganization plan was pending before the SEC. The then-proposed plan contemplated converting preferred shares into new securities, such that the insiders' purchases could yield them a financial advantage relative to other investors if the exchange ratios were favorable. The SEC disapproved the plan in relevant part, reasoning that the insiders' purchases, made while they owed fiduciary duties during the reorganization period, violated general equitable principles and should not be permitted to yield a profit. On review, the SEC's order was set aside by the court of appeals, and the SEC sought Supreme Court review. In the Supreme Court, the government urged alternative statutory justifications for the order—namely, that the SEC could deem the plan not "fair and equitable" even if the purchases were not unlawful under preexisting fiduciary law. The record, however, showed that the SEC had in fact rested its decision on generalized fiduciary principles rather than on an independent policy judgment under PUHCA.
May a reviewing court uphold an administrative agency's order on grounds not invoked by the agency, and specifically, can the SEC's disapproval of a reorganization plan be sustained when the Commission relied solely on general fiduciary principles that did not render the insiders' stock purchases unlawful under existing law?
A court reviewing administrative action must judge the propriety of that action solely by the grounds invoked by the agency. If those grounds are inadequate or improper, the court may not uphold the order by substituting what it considers to be a more adequate or proper basis. As the Court stated: "The grounds upon which an administrative order must be judged are those upon which the record discloses that its action was based."
No. The Supreme Court refused to sustain the SEC's order on legal theories the Commission had not invoked. Because the SEC rested its disapproval on generalized fiduciary principles that did not, as a matter of then-existing law, make the insiders' purchases unlawful per se, the order could not be affirmed on that basis. The Court affirmed the judgment setting aside the SEC's order and remanded to permit the Commission to proceed on a proper legal basis.
1) Statutory framework and agency rationale: PUHCA required that reorganization plans approved by the SEC be "fair and equitable." The SEC disapproved the plan because insiders purchased securities during the reorganization and supposedly breached fiduciary duties. The Commission relied on general equitable principles from corporate and fiduciary law, not on an independent statutory policy determination under PUHCA's fairness standard. 2) Error in legal premise: The Court canvassed then-prevailing corporate and fiduciary law and concluded that insider purchases of a corporation's securities during a reorganization were not per se unlawful. Absent fraud, misuse of confidential information, manipulation, or some specific breach of duty established by law, such purchases were not automatically improper. Because the SEC's order treated the purchases as inherently wrongful under general fiduciary principles, its legal premise was incorrect. 3) No post hoc rationalizations: The government argued that, even if the fiduciary-law rationale failed, the order should be upheld because the SEC could have exercised its statutory judgment that the plan was not "fair and equitable" in light of the purchases. The Court rejected this argument. Reviewing courts cannot sustain administrative action on grounds the agency did not adopt. Doing so would erode the requirement that agencies provide their own reasoned explanations, undermine accountability, and displace the agency's policymaking role with judicial conjecture. 4) Appropriate disposition: Although the SEC's stated legal theory could not sustain the order, the Court emphasized it was not deciding that the SEC lacked authority to disapprove or condition the plan under PUHCA's fairness mandate. The problem was not power but reasoning. Therefore, the proper course was to affirm the setting aside of the order and remand so the Commission could consider the matter anew and, if it chose, articulate a proper statutory basis and policy rationale. 5) Administrative law principle: The decision crystallizes a central tenet of administrative law: agency action must stand or fall on the agency's contemporaneous explanation. Courts cannot supply or imagine a better rationale after the fact. This preserves both separation of powers and the integrity of reasoned decisionmaking.
Chenery I is foundational for the "no post hoc rationalizations" rule in administrative law. It ensures that agencies carefully articulate the legal and factual bases for their decisions and that courts review those reasons, not litigation-inspired substitutes. For law students, it frames how to analyze administrative records, agency reasoning, and standards of review. It also sets the stage for Chenery II, where the Court recognized that agencies may develop policy through adjudication—so long as they say so and justify it under their statutory authority. Together, the Chenery cases shape best practices for agency decisionwriting and the contours of judicial review under, and beyond, the Administrative Procedure Act.
The Chenery doctrine holds that a reviewing court must affirm or set aside agency action based solely on the reasons the agency actually invoked at the time of decision. Courts may not uphold an order by supplying post hoc rationalizations or alternative theories not relied upon by the agency.
No. The Court did not question the SEC's statutory power under PUHCA to disapprove a plan as not "fair and equitable." It held only that the SEC's actual rationale—general fiduciary principles treating the insider purchases as inherently wrongful—was legally insufficient. The case was remanded so the SEC could reconsider and, if appropriate, explain its action under the statute.
Chenery I (1943) bars courts from affirming agency action on unstated grounds and found the SEC's stated common-law fiduciary rationale inadequate. Chenery II (1947) upheld a renewed SEC order when the Commission explicitly exercised its statutory judgment and developed policy through adjudication, explaining why the insiders' purchases rendered the plan not "fair and equitable."
Agencies must clearly articulate the legal authority and policy rationale for their decisions at the time they act, tethered to the evidentiary record. Vague appeals to general principles or post hoc litigation theories risk vacatur on judicial review.
Chenery I predates the APA (enacted in 1946) but remains fully applicable. Its reasoning complements APA review by reinforcing that courts assess whether agency action is lawful and reasoned based on the agency's stated explanation and the administrative record.
The Court stated that such purchases were not per se unlawful under then-existing fiduciary law. Without findings of fraud, manipulation, or misuse of confidential information, general equitable principles alone did not automatically bar insiders from profiting. The SEC could, however, address such concerns under its statutory fairness authority if it clearly said so and justified its decision.
Chenery I sharply delineates the roles of agencies and courts. Agencies must say what they are doing and why, anchoring their decisions in statutory authority and the record. Courts, in turn, must confine their review to those stated reasons and cannot salvage a flawed order by inventing new justifications. This allocation promotes accountability, transparency, and disciplined policymaking.
For students and practitioners, Chenery I is indispensable when briefing administrative cases, drafting agency decisions, or litigating judicial review. It reminds counsel to build a robust administrative record and to ensure that the agency's explanation matches its authority and evidence—because on review, the decision must stand or fall on the reasons the agency itself gave.
