Can a corporation be held liable for illegal activities committed by its employees?

Petitioners urge that United States v. Hare, 7 Cir., 1946, 153 F.2d 816, 819, clearly supports their contention that the illegal actions of a corporation's employees must be considered separately and not be deemed those of the corporation's acts. But there the stockholders were entirely ignorant of the illegal activities. The court comments on the lack of "awareness on the part of its other stockholders or employees" that certain officers had turned a legitimate liquor sale into an illegitimate one.
