## Facts

- Roy Garner was prosecuted for a federal gambling-related conspiracy involving interstate communications and transportation.
- In a nontax criminal trial, the government introduced Garner’s federal income tax returns as evidence.
- On the returns, Garner identified his occupation in a way that disclosed he was a gambler.
- Garner did not assert the Fifth Amendment privilege on the tax forms or decline to answer particular questions; he provided the incriminating information.
- At trial, he objected that admission of the returns violated the Fifth Amendment privilege against self-incrimination.
- The district court overruled the objection, and Garner was convicted; the Ninth Circuit affirmed on the ground that he waived the privilege by failing to claim it when filing.

## Issues

1. Whether admitting a defendant’s income tax returns in a nontax criminal prosecution violates the Fifth Amendment when the defendant voluntarily disclosed incriminating information on the returns without asserting the privilege at filing.
2. Whether failure to claim the Fifth Amendment privilege in response to specific tax-return questions renders the disclosures noncompelled and therefore admissible.

## Decision

- The Supreme Court affirmed the judgment, holding that Garner’s Fifth Amendment privilege was not violated.
- Because Garner had the right to claim the privilege on particular return items but instead answered and disclosed incriminating information, the disclosures were treated as voluntary rather than compelled.
- Absent circumstances depriving the filer of a free choice to refuse to answer, a witness who does not claim the privilege cannot later characterize the disclosures as compelled within the meaning of the Fifth Amendment.
- The Court reaffirmed that a taxpayer must file a return but may assert the privilege as to specific questions; a total refusal to file is not permitted.

## Legal Principles

- The Fifth Amendment privilege against self-incrimination is generally not self-executing in ordinary, noncustodial settings; it must be asserted at the time information is requested.
- When a taxpayer answers potentially incriminating questions on an income tax return without asserting the privilege, those answers are not treated as “compelled” and may be used in a later criminal prosecution.
- A taxpayer may not refuse to file an income tax return on Fifth Amendment grounds, but may invoke the privilege on particular entries that would be self-incriminating.
- “Compulsion” for Fifth Amendment purposes requires more than the general obligation to file; it turns on whether law or practice effectively removes a meaningful choice to claim the privilege without penalty.

## Conclusion

The Court held that the government may use a defendant’s income tax return disclosures in a nontax criminal case when the defendant chose to answer return questions without asserting the Fifth Amendment privilege at the time of filing, because the disclosures are treated as voluntary rather than compelled.
