## Facts

- Felix Gouled, a civilian contractor, was indicted with others for conspiracy to defraud the United States and for using the mails to further a fraudulent scheme.
- A government-directed acquaintance entered Gouled’s office under the pretense of a business visit and, when left alone, searched the office and removed a paper without Gouled’s knowledge or consent and without a warrant.
- Federal officers later executed two search warrants issued under the Espionage Act of 1917 and seized various papers from Gouled’s office.
- The seized materials were private business papers with no independent monetary value, taken primarily for use as evidence at trial.
- At trial, the government introduced both the surreptitiously taken paper and the warrant-seized papers over Gouled’s objections grounded in the Fourth Amendment and the Fifth Amendment privilege against self-incrimination.
- Gouled was convicted; the court of appeals certified constitutional questions to the Supreme Court.

## Issues

1. Whether a government agent’s stealthy acquisition of a paper from a suspect’s office, without warrant and without knowledge or consent, is an unreasonable search and seizure, and whether admitting the paper violates the privilege against self-incrimination.
2. Whether search warrants may constitutionally authorize seizure of private papers sought solely as evidence (“mere evidence”), rather than as contraband, fruits, or instrumentalities of crime.
3. Whether objections raised when the defendant first learns of the government’s possession at trial, or renewed at trial after denial of a pretrial return motion, are timely and must be considered.

## Decision

- The Supreme Court reversed and ordered a new trial.
- A covert entry obtained through social pretense, followed by an office search and removal of papers without warrant or consent, constituted an unreasonable search and seizure.
- Admission of a paper obtained by such unconstitutional means was held to compel the accused to be a witness against himself.
- Warrants could not validly authorize seizure of private papers taken only for evidentiary use, where the government had no property or possessory interest and the items were not contraband, fruits, or instrumentalities of crime.
- If papers are lawfully seized under a valid warrant, they may be used in prosecution for offenses other than those described in the warrant application.
- A defendant does not forfeit constitutional objections by raising them at trial when that is the first practical opportunity, and trial courts must entertain exclusion objections when unconstitutional seizure appears probable.

## Legal Principles

- The Fourth Amendment prohibits government acquisition of private papers by stealth or trickery that substitutes covert access for a warrant-based search.
- Private papers sought solely as evidence, without an independent governmental interest in the items as contraband, fruits, or instrumentalities, are not subject to seizure under a warrant for evidentiary purposes (“mere evidence” limitation as applied in this case).
- Evidence obtained through an unreasonable search and seizure is subject to exclusion, and its use may also implicate the Fifth Amendment where it effectively compels self-incriminating proof from the accused’s papers.
- Trial objections to unlawfully obtained documents are timely when the defendant first learns of the government’s possession at trial; denial of a pretrial return motion does not bar renewed exclusion requests.
- Lawfully seized materials are not constitutionally restricted to proving only the offense named in the warrant application.

## Conclusion

The Court held that covert, warrantless removal of papers from a suspect’s office violates the Fourth Amendment and that admitting such papers violates protections against compelled self-incrimination, and it further limited warrants from being used to seize private papers taken solely as “mere evidence,” requiring exclusion and a new trial.
