Katz v United States case brief

Katz v United States – 389 U.S. 347, 88 S. Ct. 507 (1967)

decided on Decided December 18, 1967

by

Justice Potter Stewart, Supreme Court of the United States

Parties

Charles Katz, petitioner and United States, respondent.

Procedure

The petitioner was tried and convicted in the U.S. District Court for the Southern District of California.

He appealed to the Ninth Circuit of the United States Court of Appeals which affirmed the conviction.

He was further appealed to the U.S. Supreme Court which overturned the conviction.

Facts

Appellant was a sports bettor from the United States who, by the mid-1960s, had established himself as “perhaps the greatest college basketball handicapper in America.

In February 1965, Katz was communicating his gambling handicaps to bookies in Boston and Miami from a public phone booth near his condominium on Sunset Boulevard in Los Angeles, California.

Unbeknownst to Katz, the FBI had initiated an investigation into his gambling activities and was secretly recording his chats using a covert listening device mounted to the phone booth outside.

after FBI investigators recorded numerous of his phone calls, Katz was arrested and charged with eight counts of intentionally sending wagering information over the phone between U.S. states.

Katz was tried in the U.S. District Court for the Southern District of California. The court convicted him based on the evidence.

However, Katz’s lawyer filed a motion to have the FBI’s recordings suppressed as evidence, arguing that the recordings were made in violation of the Fourth Amendment because the FBI agents did not have a search warrant allowing them to place their listening device, and thus should be inadmissible under the exclusionary rule. His motion was denied, and the judge determined that the recordings were admissible.

Katz appealed to the Ninth Circuit of the United States Court of Appeals. A three-judge panel of the Ninth Circuit affirmed Katz’s conviction saying that because the FBI’s eavesdropping device did not physically breach the telephone booth’s wall, no Fourth Amendment search occurred, and thus the FBI did not need a search warrant to deploy the device.

Katz then appealed to the U.S. Supreme Court.

Issue

Did the FBI’s recordings violate the petitioner’s right against unreasonable search and seizure?

Rule

In reaching its decision the court extended the Fourth Amendment to the U.S Constitution and apply the “reasonable expectation of privacy.” rule.

The Fourth Amendment’s protection from unreasonable search and seizure extends to any area where a person has a “reasonable expectation of privacy.”

Persons, not places, are protected by the Fourth Amendment from unwarranted intrusion. A person may have a reasonable expectation of privacy in his person even though he is in a public setting. When he entered the telephone booth, the petitioner did not try to hide from public view, but he did try to keep the uninvited ear out. He didn’t give up his right to do so just because he went somewhere where he could be observed.

Therefore the Government’s eavesdropping actions infringed on the petitioner’s right to privacy while using the phone booth, and thus constituted a “search and seizure” within the meaning of the Fourth Amendment.

Holding

Yes, the FBI’s recordings violate the petitioner’s right against unreasonable search and seizure thus inadmissible.

Judgment

Katz’s conviction overturned.

Concurring opinion

Justice John Marshall Harlan II concurred.

In his concurring opinion, Justice John Marshall Harlan II established the famous test called reasonable expectation of privacy test or simply referred to “Katz Test”

The case’s key takeaway has been the Katz test.

The test has two parts

  1. an individual has exhibited an actual (subjective) expectation of privacy
  2. the expectation is one that society is prepared to recognize as reasonable

If both of these conditions are present, and the government takes action that breaches this “expectation,” the government has infringed on the individual’s Fourth Amendment rights.

Dissenting opinion

Justice Hugo Black dissented.

Hugo argued that the Fourth Amendment was primarily intended to protect “things” against physical search and seizure, not people’s privacy.

Furthermore, Black contended that modern wiretapping was akin to eavesdropping, which existed at the time the Bill of Rights was drafted. If the Fourth Amendment’s drafters had intended for it to protect against eavesdropping, Black argued, they would have inserted the appropriate language.
