Summary

Background

Federal grand jury witnesses in separate cases refused to answer questions they said were based on their telephone conversations that federal agents had allegedly intercepted illegally. In Los Angeles, the district court held the witnesses in contempt and committed them under the statute that permits confinement for refusing to testify; in Pennsylvania, similar witnesses with immunity were also jailed after refusing to answer. The Courts of Appeals were split, and the cases reached the Supreme Court for review.

Reasoning

The Court framed the core question simply: may a grand jury witness use Title III’s ban on using unlawfully intercepted communications as a defense to a contempt order? Relying on the plain language and congressional findings in Title III, the Court found that §2515’s evidentiary prohibition reflects a strong congressional policy to protect privacy and to prevent courts from becoming complicit in illegal surveillance. The Court also pointed to a later statute, §3504, as confirming Congress expected witnesses to be able to raise such claims. On that basis, the Court held witnesses may assert §2515 as a defense and reversed the Ninth Circuit while affirming the Third Circuit, remanding for factual proceedings.

Real world impact

Practically, witnesses called before grand juries can refuse to answer when questioning would rely on illegally intercepted communications, and courts must consider the statutory bar before punishing refusal. The ruling does not resolve every situation; if the Government produced a valid interception order or affirmatively denies surveillance, different outcomes may follow and the district court must sort those facts on remand.

Dissents or concurrances

Justices Douglas and White wrote concurring opinions emphasizing Fourth Amendment concerns and practical limits when the Government shows a court order. Justice Rehnquist dissented, warning the decision conflicts with legislative history and long-standing grand jury practices.
