## Facts

- Willie Israel Alderman and others were convicted in separate federal prosecutions involving interstate threats and national security offenses.
- After convictions were affirmed, petitioners learned the government had conducted warrantless electronic surveillance of a petitioner’s business premises.
- The Supreme Court vacated and remanded for determination whether the convictions were tainted by unlawful surveillance.
- The government sought to modify the remand procedure by having the district judge review surveillance materials in camera and disclose only portions the judge deemed arguably relevant.
- Petitioners argued that defendants with Fourth Amendment standing were entitled to access all surveillance records related to surveillance they could challenge.

## Issues

1. Who has Fourth Amendment standing to seek suppression of evidence derived from unlawful electronic surveillance, including whether codefendants or coconspirators may object to surveillance directed at another.
2. Whether a defendant may suppress evidence when the government unlawfully overheard the defendant’s conversations or conversations on the defendant’s premises even if the defendant was absent or not a participant.
3. Whether, in a taint inquiry, the government may rely on exclusive in camera judicial inspection of surveillance records, or must disclose surveillance materials to defendants who have standing.

## Decision

- The Court held that Fourth Amendment standing is personal; only those whose own rights were violated by the surveillance may seek suppression, and codefendants or coconspirators have no special standing.
- The Court held a defendant has standing to challenge unlawful surveillance that overheard the defendant’s own conversations and surveillance that captured conversations occurring on the defendant’s premises, whether or not the defendant was present or participated.
- The Court rejected the government’s proposed exclusive in camera screening process; surveillance records as to which a defendant has standing must be turned over to the defendant without being screened solely by the trial judge.
- The case was to proceed under a taint-hearing approach in which the government must show its evidence was not derived from the unlawful surveillance, with disclosure enabling adversarial testing.

## Legal Principles

- Fourth Amendment rights are personal; the exclusionary rule may be invoked only by persons whose own privacy interests were invaded, not by those harmed only by the use of evidence.
- Standing exists for unlawful interception of a defendant’s own conversations and for unlawful surveillance of the defendant’s premises that captures conversations there, regardless of the defendant’s participation or presence.
- In taint determinations following unlawful electronic surveillance, exclusive in camera judicial review is an insufficient substitute for adversarial scrutiny when deciding whether surveillance contributed to the prosecution’s case.
- Once illegality and standing are established, the government must disclose the relevant surveillance records to the defendant to permit effective litigation of taint and derivative use.

## Conclusion

The Court limited suppression claims in electronic surveillance cases to defendants whose own conversations or premises were unlawfully monitored, but required that defendants with standing receive the surveillance records without exclusive in camera judicial screening so they can contest whether the prosecution’s evidence was tainted.
