4th Amendment Flashcards
What is a search?
When there has been a violation of a reasonable expectation of privacy or a physical intrusion into a constitutionally protected space
What main cases cover search?
Katz, Jones, Jardines
What clause predominates of the 4th Amendment?
Warrant Clause
What is reasonableness clause?
fair possibility that criminal activity is afoot
What is probable cause?
minimum necessary showing to obtain a warrant, not whether searches/seizures are necessarily reasonable
Who are “the people” under the 4th amendment?
What case covers “the people”?
The People: The 4th Amendment applies to members of the national community or those with sufficient connection with the country to be part of this community, not just citizens
U.S. v. Verdugo-Uquidez (1990): Mexican citizens in Mexico are not party of “the people” because the 4th amendment was intended to protect the people form the tyranny of their own government
What is standard for search?
Standard for a search: Katz (reasonable expectation) of privacy and Jones (trespass)
What case governed before Katz? (facts and holding)
Olmstead v. U.S. (1933): wiretapping phones from street –> the 4th amendment guards only against physical intrusions into constitutionally protected areas (person, house, paper or effect)
What are the facts/holding of Katz?
Facts: outside of public booth used by Katz acting on suspicion Katz was transmitting gambling information over the phone to clients in other states
Holding: 4th amendment requires a search warrant to wiretap/listen to a public phone, the 4th amendment protects people, not places
What is the test Katz establishes?
The reasonable expectation of privacy test
1. The person has exhibited a subjective expectation of privacy (purely factual) AND
2. That expectation of privacy is one that society is prepared to recognize as reasonable or legitimate (objective)
What are the two ways the Court views the second prong of the Katz analysis?
Empirical (“reasonable”): is it possible for someone to have access to this information?
Normative (“legitimate”): does the public ordinarily have access to this information?
What is Harlan’s critique of the prongs of Katz?
1st prong problem: our expectations and the risks we assume are reflections of the laws that translate into rules/customs/values of the past and present
2nd prong problem: what is “reasonably expected” may be determined by the government to favor its own conduct rather than society’s
What is the Jones facts/holding?
Facts: GPS jeep tracker and drugs
Holding: warrantless use of a tracking device on his vehicle was a physical trespass, so was a search
- There is no expectation of privacy in public movements, so this is not a search under Katz. but this is a trespass.
- Trespass Test: A search occurs when there is a physical trespass into a constitutionally protected area (persons, houses, papers, and effects)
What is Alito and Sotomayor concurrence in Jones?
Bonus Holding (Alito Concurrence): police surveillance of a citizen’s activity can constitute a search if it is pervasive and prolonged, even though the activity is in public (28 days) most people would think long-term GPS surveillance impinges on reasonable expectations of privacy (except in the most extraordinary offenses)
Sotomayor Concurrence: Agrees with Scalia that there are two tests (Katz and Trespass). Agrees with Alito that this would be a search under Katz; previews issues with tech + gov intrusion
What is Jardines facts/holding?
Facts: dog sniff of porch for smell of marijuana
Holding: Bringing a drug-sniffing dog onto D’s porch was a search because it was a physical intrusion into a constitutionally protected area: the home/curtilage.
What does Yassky hold?
plaintiff must establish a property interest in the protected area at the time of intrusion to claim government physically intruded on one’s constitutionally protected area
What is subjective manifestation under Katz?
What case exemplifies this?
Individuals must take affirmative steps to protect their privacy interests otherwise a police inspection will not constitute a search
Bellina: Officer used step ladder to peer in window, but defendant made no attempt to cover window therefore did not sufficiently manifest a subjective privacy
Can police search an abandoned property?
Police detention and investigation of abandoned property does not trigger 4th amendment protection
What is the open fields doctrine?
What case governs this?
Open fields are not protected by the 4th amendment
- Oliver: “open fields” doctrine was still valid after Katz because a person does not have a legitimate expectation of privacy in an open field (trespass signs don’t change analysis)
How do you determine what curtilage is?
Four factors to determine if an area is curtilage and thus protected by 4th amendment:
1) Proximity of area to the house
2) Whether the area is included w/in an enclosure surrounding the house
3) Nature of the uses of the area
4) Steps taken by resident to protect are from observation
Even if property is within a curtilage, a visual inspection of the property from an open field or public space does not (no reasonable expectation of privacy, Katz #2)
What is Third Party Doctrine?
Third Party Doctrine: If information is disclosed to a third party, it is not reasonable to expect it to be private (prong 2) (An extension of open fields)
Is consensual electronic surveillance under TPD protected? (what case)
U.S. v. White (1971): Defendant had no reasonable expectation of privacy in conversation discussing illegal avidity with another person
Are financial records under TPD protected?
U.S. v. Miller (1976): Because the bank has the records, defendant has no reasonable expectation of privacy in the records
Are pen registers under TPD protected?
Smith v. Maryland (1979): Use of a pen register is not a search because third party telephone company knows what numbers you call. No reasonable expectation of privacy
