In NLRB v. Houston Chronicle Publishing Co., 300 F.2d 273 (5th Cir. 1962), the court had applied the Universal Camera test, Universal Camera Corp. v. NLRB, 340 U.S. 474, 71 S.Ct. 456, 95 L.Ed. 456 (1951), to findings of fact made by the Board in evaluating election propaganda, a substantive determination by the Board, but the Court noted that cases cited by the Board seeking to limit review to whether the Board acted arbitrarily or capriciously "in fact support the view we [have taken]."
