Shapiro v. United States (335 U.S. 1)/Dissent Jackson
Mr. Justice JACKSON, with whom Mr. Justice MURPHY agrees, dissenting.

The protection against compulsory self-incrimination, guaranteed by the Fifth Amendment, is nullified to whatever extent this Court holds that Congress may require a citizen to keep an account of his deeds and misdeeds and turn over or exhibit the record on demand of government inspectors, who then can use it to convict him. Today's decision introduces a principle of considerable moment. Of course, it strips of protection only business men and their records; but we cannot too often remind ourselves of the tendency of such a principle, once approved, to expand itself in practice 'to the limits of its logic.' That it has already expanded to cover a vast area is apparent from the Court's citation of twenty-six federal statutes that present parallels to the situation here under review. It would, no doubt, simplify enforcement of all criminal laws if each citizen were required to keep a diary that would show where he was at all times, with whom he was, and what he was up to. The decision of today, applying this rule not merely to records specially required under the Act but also to records 'customarily kept,' invites and facilitates that eventuality.

The practice approved today obviously narrows the protections of the Fifth Amendment. We should not attribute to Congress such a purpose or intent unless it used language so mandatory and unmistakable that it left no alternative, and certainly should not base that inference on 'legislative history' of such dubious meaning as exists in this case. Congress, if we give its language plain and usual meaning, has guarded the immunity so scrupulously as to raise no constitutional question. But if Congress had overstepped, we should have no hesitation in holding that the Government must lose some cases rather than the people lose their immunities from compulsory self-incrimination. However, in this case, the plain language of Congress requires no such choice. It does require, in my view, that this judgment be reversed.
