Summary

Background

A former company executive, who previously testified to the Department of Justice under a grant of federal "use" immunity, was later subpoenaed for a civil deposition in consolidated antitrust suits brought by purchasers of corrugated containers. At the deposition lawyers read questions taken from his immunized grand jury transcript and asked him to confirm his prior answers. He invoked his Fifth Amendment right and the district court ordered him to answer, holding him in contempt when he refused. A court of appeals panel affirmed, but the en banc court reversed, and the Supreme Court agreed to review the conflict.

Reasoning

The Court examined the federal use-immunity statute (18 U.S.C. งง6001-6005), its legislative history, and prior cases about the exclusion of "fruits" of compelled statements. The majority stressed three competing interests: private plaintiffs’ need for evidence, the Government’s interest in limiting the scope of an immunity grant, and a witness’s interest in certain protection against self-incrimination. The Court concluded that a civil court cannot compel deposition testimony that closely tracks prior immunized testimony over a valid assertion of the Fifth Amendment unless the Executive has provided a new, authorized assurance of immunity at that deposition.

Real world impact

The decision means witnesses who previously testified under federal use immunity can decline civil deposition questions that merely repeat that testimony unless prosecutors grant immunity again. Private litigants cannot force such testimony by relying on earlier immunity orders, and courts may not substitute for the Executive in granting immunity. This preserves prosecutorial control over when immunization applies and avoids turning use immunity into transactional immunity.

Dissents or concurrances

Several Justices concurred in the judgment but differed on statutory or constitutional analysis. Justice Stevens (joined by Justice O’Connor) dissented, arguing the deposition confirmations were within the statutory immunity and the witness should have been required to answer.
