Actually it happened way before 1970 when Dodge sued Ford.
Dodge v. Ford Motor Company, 204 Mich. 459, 170 N.W. 668 (Mich. 1919) is a case in which the Michigan Supreme Court held that Henry Ford had to operate the Ford Motor Company in the interests of its shareholders, rather than in a charitable manner for the benefit of his employees or customers.
