Summary

Mahlon Pitney Mallinckrodt Chemical Works v. Missouri…

The legislature may reasonably have concluded that, for these and other reasons, corporations are peculiarly apt instruments for establishing and effectuating those trusts and combinations against which the prohibition of the statute is directed, that their business affiliations are not so easily discovered and traced as those of individuals, and that there was therefore a peculiar necessity and fitness in annually requiring from each corporation a solemn assurance of its nonparticipation in the prohibited practices.

From the undisputed evidence it appears that the refusal to file the affidavit was based upon the general theory that the corporation was not obliged to make any such disclosure as is required by § 10,322, and not upon the ground of any ambiguity respecting the term 'trust certificate.' As has been often pointed out, one who seeks to set aside a state statute as repugnant to the Federal Constitution must show that he is within the class with respect to whom the act is unconstitutional, and that the alleged unconstitutional feature injures him.
