Cox v. United States

1972-05-15

Headline: Court declines to review a wiretap case, leaving a ruling that phone recordings made during narcotics surveillance could be used to convict a man of bank robbery.

Holding: The Supreme Court refused to review the appeals court’s decision, leaving in place the ruling that phone conversations recorded under a narcotics-targeted wiretap could be used to convict on an unrelated bank robbery charge.

Real World Impact:

Allows prosecutors to use unrelated conversations recorded during targeted wiretaps.
Makes it harder for defendants to exclude evidence captured outside a warrant’s stated subject.
Leaves the lower-court rule in place unless the Supreme Court later reopens the issue.

Topics: wiretapping, privacy rights, criminal trials, police surveillance

Summary

Background

A man was convicted of bank robbery after the Government used tape recordings of his telephone calls at trial. Federal agents had obtained a court order under a federal wiretap law to listen for narcotics-related conversations. While listening, they heard and recorded talk about a bank robbery, and those tapes were introduced at trial despite objections that the order covered only drug communications.

Reasoning

The appeals court said that once the listening device was lawfully placed on the target phone line, anything overheard could be treated like something in "plain view" and therefore used by prosecutors. The Supreme Court declined to review that ruling, so the appeals court decision stands for now. One Justice wrote a dissent saying the wiretap law creates a broad dragnet and conflicts with the Fourth Amendment’s protection against general warrants.

Real world impact

Because the high court refused to take the case, the lower-court rule allowing such overheard conversations to be used at trial remains in force. That outcome affects defendants whose unrelated conversations are picked up during targeted wiretaps, and it leaves unresolved whether the federal wiretap law improperly permits sweeping surveillance. The denial is not a final statement on the law’s constitutionality and could change if the Court later agrees to hear the issue.

Dissents or concurrances

One Justice dissented, arguing the statute authorizes an indiscriminate dragnet and should be held to violate the Fourth Amendment; two other Justices would have granted review.
