1 Am. Jur. 2d 806

1 Am. Jur. 2d 806. That the rules of judicial review are parts of administrative law is confirmed by the statement that it is a "simple but fundamental rule of administrative law" 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. (Securities and Exchange Commission v. Chenery Corp., 332 U.S. 194, L. Ed. 1955, 67 S. Ct. 1575, 1760 [1947].)
