Facts
- Fremont Weeks was arrested in Kansas City, Missouri, without an arrest warrant.
- While Weeks was in custody, local police entered his home without a search warrant, using a key obtained through a neighbor, and seized papers and other items; the materials were later turned over to a U.S. marshal.
- Later the same day, the U.S. marshal and officers again entered the home without a search warrant and seized additional letters and envelopes from a drawer.
- The seized papers and letters were introduced at trial and were substantially the only evidence supporting Weeks’s conviction for using the mails to transport lottery tickets in violation of § 213 of the Criminal Code.
- Before trial, Weeks sought return of the seized items and objected to their use as violating the Fourth and Fifth Amendments; the district court returned some property but allowed retention and use of certain letters and papers.
- Weeks was convicted, and he sought Supreme Court review by writ of error.
Issues
- Whether federal officers’ warrantless entry into a home and seizure of private papers and letters violates the Fourth Amendment.
- Whether, upon a timely pretrial request for return of wrongfully seized property, a federal court may retain the materials and allow their use as evidence in a federal criminal prosecution.
Decision
- The Supreme Court unanimously held that the warrantless seizure of letters and private documents from Weeks’s home violated the Fourth Amendment.
- Because Weeks made a timely application for return of the seized materials, the federal court was required to order their return and could not permit their use in evidence.
- Admission of the unlawfully seized papers was prejudicial error; the conviction was reversed and the case remanded.
- The Court stated that the Fourth Amendment, as applied in the case, constrained the federal government and its agents, not state officers acting independently.
Legal Principles
- Warrantless entry into a home and seizure of a person’s papers and effects by federal officers is an unreasonable search and seizure barred by the Fourth Amendment.
- To give practical effect to the Fourth Amendment, federal courts must order the return of property seized in violation of the Amendment when the defendant makes a timely application before trial.
- Evidence obtained through a federal Fourth Amendment violation may not be used by the government in a federal criminal trial when properly challenged; exclusion operates as the necessary judicial remedy to prevent courts from sanctioning unconstitutional seizures.
- Prior precedent permitting use of incriminating papers incidentally seized during execution of a valid warrant does not apply where there was no warrant and the entire seizure was unlawful.
Conclusion
The Court reversed Weeks’s conviction, holding that federal officers’ warrantless seizure of private papers from a home violated the Fourth Amendment and that, upon a timely request, federal courts must order the materials returned and exclude them from evidence in federal prosecutions.
