Berger v. New York
The Supreme Court struck down New York's law letting judges authorize police eavesdropping devices, ruling that the law was written so broadly that it amounted to the kind of open-ended "general search" the Fourth Amendment was written to forbid.
The decision meant that bugging a person's office or home now had to meet the same core protections as a conventional search warrant — a specific crime, a described target, and real limits on how long and how broadly officers could listen in.
“Few threats to liberty exist which are greater than that posed by the use of eavesdropping devices.”
The majority's warning about the dangers electronic surveillance poses to personal privacy.
How it got here: A New York trial court convicted Berger using the eavesdrop recordings; the Appellate Division and New York's Court of Appeals affirmed, and the Supreme Court agreed to review the case.
The Case in Depth
What happened
A bar owner complained that liquor officials had raided his business in retaliation for refusing to pay a bribe. That tip led investigators to bug the office of an attorney and then a second office, uncovering a scheme to sell liquor licenses. Ralph Berger was convicted of conspiring to bribe the head of New York's Liquor Authority, based almost entirely on recordings made under New York's eavesdropping law, which let judges authorize hidden listening devices for up to two months at a time.
The question before the Court
Could New York let its judges authorize police to bug someone's office for months at a time based only on a general statement that evidence of some crime might turn up?
The Court's answer
No — the Court ruled that New York's eavesdropping statute was unconstitutional on its face because it authorized a general search rather than the kind of narrowly targeted search the Fourth Amendment demands. The law let police get court orders to bug someone's office for up to two months, renewable, without ever having to specify what particular crime was suspected or which conversations were being sought.
That combination — no requirement to name a specific offense, no particular description of the conversations to be seized, an open-ended time period, and no requirement to notify anyone, show urgency, stop once evidence was found, or report back to the judge — left far too much discretion in the hands of the officers doing the listening. The Court held that this made the law function like the "general warrants" the Fourth Amendment was written to forbid, so Berger's conviction, built almost entirely on evidence gathered this way, could not stand.

Why it matters
Anyone whose conversations might be recorded by government eavesdropping gained a clearer constitutional shield: officials can no longer get broad, months-long listening permission on a vague suspicion. Police departments and legislatures had to rewrite eavesdropping and wiretapping rules to include real time limits, particular descriptions of what they were listening for, and stopping points once evidence was found.
What changes now
Because the Court found New York's statute unconstitutional on its face, Berger's conviction could not stand and could not be retried using the tainted recordings. States and Congress faced pressure to rewrite eavesdropping and wiretapping laws with tighter time limits, particular descriptions of suspected crimes and conversations, and procedures for reporting back to the authorizing judge. This is a final merits decision, not a temporary order.
What this does not decide
The Court did not rule that all judicially authorized eavesdropping is unconstitutional, and it left open whether the specific affidavits behind Berger's eavesdrop orders showed probable cause. It also did not disturb earlier rulings allowing eavesdropping without a physical trespass or with the consent of a participant to the conversation.
Concurrences and dissents
Concurrence — Justice Douglas
Justice Douglas joined the majority but wrote separately to say it did not go far enough. He argued that any electronic eavesdropping is inherently a search for "mere evidence," which he believed violates the Fourth and Fifth Amendments no matter how carefully a warrant is drafted, and he objected to the intrusion of turning a home or office into a place where an unseen government agent is always listening.
Concurrence — Justice Stewart
Justice Stewart agreed the conviction should be reversed but disagreed that the statute itself was unconstitutional. He thought New York's law was actually stricter than the Fourth Amendment requires, and that the real problem was that the affidavits supporting the Steinman eavesdrop order did not show adequate probable cause in this particular case.
Dissent — Justice Black
“Notwithstanding petitioner's obvious guilt, however, the Court now strikes down his conviction in a way that plainly makes it impossible ever to convict him again.”Black's objection that the ruling frees a man he believed was clearly guilty of bribery.
Justice Black argued the Fourth Amendment contains no rule against admitting evidence from an unreasonable search, and that the exclusionary rule rests on the Court's supervisory power, not the Amendment itself. He also argued the Court effectively rewrote the Amendment by substituting "privacy" for its actual text, making it impossible for any state to ever draft a valid eavesdropping law.
Dissent — Justice Harlan
Justice Harlan objected that the Court bypassed New York's own courts, which had already construed the "reasonable grounds" standard to match probable cause, and ignored the state's efforts to build in safeguards. Examining the actual Steinman affidavits, he concluded they satisfied the Fourth Amendment's particularity and probable-cause requirements and would have affirmed the conviction.
Dissent — Justice White
Justice White argued the Court should have asked only whether this particular search was reasonable rather than inventing new warrant requirements nowhere found in the Fourth Amendment or prior cases. Pointing to law-enforcement data on organized crime and corruption, he argued regulated eavesdropping like New York's was a reasonable and valuable investigative tool and would have affirmed.
How the Court got there
The legal reasoning, step by step
- The Court first confirmed that a private conversation counts as something the Fourth Amendment protects, and that using an electronic device to capture it is a "search" within the meaning of the Amendment — extending decades of case law that had wavered on whether spoken words, not just physical objects, could be searched or seized.
- Because New York's law authorized a search, the Court measured it against the Fourth Amendment's particularity requirement — the rule that a warrant must specifically describe the place to be searched and the things to be seized, so officers aren't left to decide for themselves what to look for.
- The Court found the law let officers eavesdrop without any requirement to specify what particular crime was suspected or which conversations they were after, giving them what the opinion called a "roving commission" to listen to anything said in the room.
- The Court treated the law's two-month eavesdropping period, renewable without a fresh showing of probable cause, as the equivalent of a long series of repeated searches under a single authorization, since surveillance ran continuously rather than being executed once and completed.
- The law's failure to require notice, a showing of urgent circumstances before entering without consent, a stopping point once the sought evidence was captured, or a report back to the judge on what was actually seized left the search almost entirely to the discretion of the officers involved.
- Taken together, these gaps made the statute function like the old British "general warrants" the Fourth Amendment was written to abolish, so the Court held the law unconstitutional on its face under the Fourth and Fourteenth Amendments.
Doctrinal impact
Cases affected by this decision
Limits Olmstead v. United States (277 U.S. 438)
Its view that wiretapping without physical entry falls outside the Fourth Amendment was undercut by later cases treating conversations as protected.
Reaffirms Weeks v. United States (232 U.S. 383)
The Court relied on this case's rule excluding illegally seized evidence from federal courts as the basis for its analysis.
Reaffirms Mapp v. Ohio (367 U.S. 643)
The Court reaffirmed that Fourth Amendment protections, including the exclusionary rule, bind the states.
