This case is here for the second time. In S.E.C. v. Chenery Corporation, 318 U.S. 80, 63 S.Ct. 454, 87 L.Ed. 626, we held that an order of the Scurities a nd Exchange Commission could not be sustained on the grounds upon which that agency acted. We therefore directed that the case be remanded to the Commission for such further proceedings as might be appropriate. On remand, the Commission reexamined the problem, recast its rationale and reached the same result. The issue now is whether the Commission's action is proper in light of the principles established in our prior decision.
When the case was first here, we emphasized a simple but fundamental rule of administrative law. That rule is to the effect that a reviewing court, in dealing with a determination or judgment which an administrative agency alone is authorized to make, must judge the propriety of such action solely by the grounds invoked by the agency. If those grounds are inadequate or improper, the court is powerless to affirm the administrative action by substituting what it considers to be a more adequate or proper basis. To do so would propel the court into the domain which Congress has set aside exclusively for the administrative agency.
We also emphasized in our prior decision an important corollary of the foregoing rule. If the administrative action is to be tested by the basis upon which it purports to rest, that basis must be set forth with such clarity as to be understandable. It will not do for a court to be compelled to guess at the theory underlying the agency's action; nor can a court be expected to chisel that which must be precise from what the agency has left vague and indecisive. In other words, 'We must know what a decision means before the duty becomes ours to say whether it is right or wrong.' United States v. Chicago, M., St. P. & P.R. Co., 294 U.S. 499, 511, 55 S.Ct. 462, 467, 79 L.Ed. 1023.
Applying this rule and its corollary, the Court was unable to sustain the Commission's original action. The Commission had been dealing with the reorganization of the Federal Water Service Corporation (Federal), a holding company registered under the Public Utility Holding Company Act of 1935, 49 Stat. 803, 15 U.S.C.A. § 79 et seq. During the period when successive reorganization plans proposed by the management were before the Commission, the officers, directors and controlling stockholders of Federal purchased a substantial amount of Federal's preferred stock on the over-the-counter market. Under the fourth reorganization plan, this preferred stock was to be converted into common stock of a new corporation; on the basis of the purchases of preferred stock, the management would have received more than 10% of this new common stock. It was frankly admitted that the management's purpose in buying the preferred stock was to protect its interest in the new company. It was also plain that there was no fraud or lack of disclosure in making these purchases.
But the Commission would not approve the fourth plan so long as the preferred stock purchased by the management was to be treated on a parity with the other preferred stock. It felt that the officers and directors of a holding company in process of reorganization under the Act were fiduciaries and were under a duty not to trade in the securities of that company during the reorganization period. 8 S.E.C. 893, 915-921. And so the plan was amended to provide that the preferred stock acquired by the management, unlike that held by others, was not to be converted into the new common stock; instead, it was to be surrendered at cost plus dividends accumulated since the purchase dates. As amended, the plan was approved by the Commission over the management's objections. 10 S.E.C. 200.
