Summary

Portrait of William O. Douglas William O. Douglas Zap v. United States — Dissent

As to what is to be taken, nothing is left to the discretion of the officers executing the warrant.' If where a search instituted under the legal process of a warrant, which also authorizes seizure, does not permit seizure of articles other than those specified, statutory and contractual authority merely to search cannot be considered sufficient to grant that power. The Government relies on a doctrine quite inapposite here. If, in the course of a valid search, materials are uncovered, the very possession or concealment of which is a crime, they may be seized.

And that is the issue here. The legality of a search does not automatically legalize every accompanying seizure.
The Government argues very simply that the seizure was authorized since the seized items were uncovered in a lawful search. But this is to overlook what we ruled in Marron v. United States, 275 U.S. 192, 196, 48 S.Ct. 74, 76, 72 L.Ed. 231: 'The requirement that warrants shall particularly describe the things to be seized makes general searches under them impossible and prevents the seizure of one thing under a warrant describing another.

The sole question before us is the validity of the seizure.
I agree that the government had authority, as a result of its contract with the petitioner and the relevant statutes, to inspect the petitioner's books and records, 44 Stat. 780, 787, 10 U.S.C. § 310 (l) , 10 U.S.C.A. § 310 (l) , 56 Stat. 176, 185, 50 U.S.C.App. § 643, 50 U.S.C.A.Appendix, § 643, and that the Navy Department could utilize members of the F.B.I. for this purpose. Accordingly, the search was legal and the inspectors could testify to what they had gleaned from the inspection.
