## Facts

- New York investigators suspected Ralph Berger of bribery and corruption connected to liquor licensing.
- Authorities sought and obtained an ex parte judicial order under New York Code of Criminal Procedure § 813-a to conduct electronic eavesdropping in Berger’s private office.
- The order authorized installation and use of a listening device to intercept oral communications for up to 60 days, with statutory allowance for extensions.
- Intercepted conversations were introduced at Berger’s criminal trial.
- Berger was convicted; the New York Court of Appeals affirmed, upholding both the statute and the surveillance order.
- The Supreme Court granted review to assess whether § 813-a and the order complied with the Fourth Amendment as applied to the states through the Fourteenth Amendment.

## Issues

1. Whether electronic eavesdropping of conversations in a private office constitutes a Fourth Amendment search and seizure requiring warrant-like safeguards.
2. Whether § 813-a and orders issued under it satisfied Fourth Amendment requirements of probable cause, particularity, and limits that prevent general, exploratory surveillance.
3. Whether the statute’s duration, scope, and procedural features (including minimization, notice, and judicial supervision) were constitutionally adequate.

## Decision

- The Supreme Court reversed, holding § 813-a unconstitutional on its face.
- The Court treated electronic eavesdropping as a Fourth Amendment search and seizure.
- The statute was invalid because it authorized the equivalent of a general warrant by permitting broad interception of conversations without adequate particularity and safeguards.
- Because the statutory scheme was unconstitutional, the interception and use of Berger’s conversations were unlawful.

## Legal Principles

- Electronic eavesdropping is subject to the Fourth Amendment and may be more intrusive than a conventional physical search.
- A valid authorization for surveillance must contain warrant-like protections, including:
  - Probable cause determined by a neutral magistrate.
  - Particularity that meaningfully limits what communications may be seized and for what offenses.
  - Strict limits on duration and scope, avoiding open-ended or continuing searches.

- Authorization regimes that permit officials to decide what to “seize” while monitoring, without effective limits, resemble general warrants and are unreasonable under the Fourth Amendment.
- Constitutional sufficiency is assessed not only by judicial approval in form, but by whether the governing statute and order impose enforceable constraints such as minimization and meaningful oversight.

## Conclusion

The Court invalidated New York’s wiretap statute because it permitted wide-ranging, prolonged electronic surveillance without the specific limits and procedural protections the Fourth Amendment requires for searches, rendering the scheme akin to a general warrant.
