United States v. Donovan
The Supreme Court ruled that federal wiretap law required investigators to name every person they had probable cause to believe was committing the crime and would be overheard, and also required them to tell the judge who else got recorded so he could decide about notifying them.
But the Court also held that the FBI's failure to do those two things in this gambling case did not require throwing out the recorded conversations as evidence, because the missing names did not undermine the judge's original decision to allow the wiretap.
“We therefore conclude that a wiretap application must name an individual if the Government has probable cause to believe that the individual is engaged in the criminal activity under investigation and expects to intercept the individual’s conversations over the target telephone.”
The Court's core holding on who must be named in a wiretap application.
How it got here: A federal trial court suppressed the wiretap evidence for all five men; the Sixth Circuit affirmed; the government asked the Supreme Court to review the suppression rulings.
The Case in Depth
What happened
FBI agents wiretapped phones in Ohio to investigate an illegal gambling operation run by several named men. During the surveillance, agents overheard other people — including Donovan, Robbins, and Buzzacco — discussing gambling, but did not add their names when applying to extend the wiretap. Two other men, Merlo and Lauer, were never told afterward that their calls had been recorded, apparently due to a clerical mistake.
The question before the Court
When FBI agents wiretapping a gambling ring left some suspects' names off an application and off a notice list, did that mean the recorded calls had to be thrown out of court?
The Court's answer
Partly — the Court agreed that the wiretap law required the FBI to name everyone it had probable cause to believe was committing the crime and would be recorded, and to give the judge enough information to decide whether overheard-but-unnamed people deserved after-the-fact notice. The FBI fell short on both counts here.
But the Court held that falling short did not mean the recordings had to be suppressed. Applying the standard from earlier cases, it found these particular omissions did not undermine the judge's original probable-cause findings or Congress's core goal of limiting wiretaps to situations that truly justify them, so the evidence could still be used at trial.

Why it matters
The decision tells police and prosecutors how careful they must be when applying for wiretaps, while also reassuring them that small paperwork lapses in naming targets or notifying overheard parties won't automatically wreck a prosecution. That balance shaped how wiretap evidence has been challenged in criminal cases ever since.
What changes now
The case goes back to the lower court, and the suppressed wiretap evidence can now be used against Donovan, Robbins, Buzzacco, Merlo, and Lauer in the underlying gambling prosecution. The ruling is a final decision on the meaning of the wiretap statute's naming and notice rules, though it leaves open what would happen if a similar violation were shown to be intentional rather than an oversight.
What this does not decide
The Court did not decide whether suppression would be required if the government intentionally, rather than inadvertently, left someone off a wiretap application or notice list to keep information from the judge. It also left the same question open for cases where agents knew in advance that no notice would ever be given.
Concurrences and dissents
How the Justices voted
Majority (1). Justice Powell (author).
Separate writings (2). Justice Burger (author of a opinion).
Dissent (1). Justice Marshall (author).
Concurrence — Justice Burger
Chief Justice Burger agreed the recordings should not be suppressed but disagreed with the Court's reading of the naming requirement itself. He argued the statute, by its precise wording, required naming only the primary user of the tapped phone, not everyone likely to be overheard, and that Congress's rejection of a broader suppression amendment independently barred these defendants from seeking suppression at all.
Dissent in part — Justice Marshall
Justice Marshall agreed that the naming and notice requirements were violated but argued the evidence should have been suppressed. He contended the naming rule plays a real, substantive role because it triggers other protections like disclosure of prior wiretap applications and mandatory notice, so skipping it undermines Congress's system regardless of whether it would have changed the judge's original decision.

Concurrence in part — Justice Stevens
Justice Stevens joined the Court's holdings that the naming and notice requirements were violated, but for the reasons given in Justice Marshall's opinion, he dissented from the Court's conclusion that suppression was not required.
How the Court got there
The legal reasoning, step by step
- The Court first asked what the wiretap law's naming requirement actually demands, rejecting the government's argument that only the 'principal target' using the tapped phone needs to be named; instead, anyone the government has probable cause to believe is committing the crime and will be recorded must be named, regardless of which phone they call from.
- The Court then addressed the judge's notice duty, holding that because the law lets a judge decide whether overheard-but-unnamed people deserve notice, investigators must routinely give the judge enough information — at least a description of the categories of people overheard, or a complete list if one is offered — to make that call.
- Turning to whether these violations required suppression, the Court applied the test from two earlier decisions (Giordano and Chavez): evidence must be thrown out only when a violated requirement 'directly and substantially' implements Congress's goal of limiting wiretaps to situations that truly call for them, not for every technical slip.
- Applying that test, the Court found the naming failure did not affect whether the judge would have authorized the wiretap in the first place, since the judge's decision rested on separate probable-cause findings about the phones and the ongoing crime, not on a complete list of every future speaker.
- The Court similarly found that the missing notice to two men did not make the earlier interception unlawful, because notice happens only after recording is already finished and lawful, and Congress designed notice mainly to reassure the public that wiretaps are used properly rather than as a gatekeeping check on the wiretap itself.
- Concluding that the statutory violations here did not go to the heart of Congress's system for limiting wiretap use, the Court held suppression was not required, even while urging the government to follow the law's requirements more carefully going forward.
Doctrinal impact
Cases affected by this decision
Distinguishes United States v. Giordano (416 U. S. 505)
The Court said this case, unlike Giordano, did not bypass a limitation Congress placed on when wiretaps could be used at all.
Reaffirms United States v. Chavez (416 U. S. 562)
The Court relied on Chavez's rule that not every statutory slip makes an interception unlawful, applying it here to reach the same result.
Distinguishes United States v. Kahn (415 U. S. 143)
The Court called Kahn relevant but not controlling because it addressed a different identification question.
