4th Amendment Exceptions to the Warrant Requirement

These flashcards cover various cases and principles related to the Fourth Amendment and its exceptions, focusing on search and seizure standards, privacy rights, and legal precedents.

Camara v. Municipal Court of the City and County of San Francisco

The Court established that the Fourth Amendment applies to administrative inspections of private residences, requiring an administrative warrant based on a lesser standard of probable cause (area-wide conditions) rather than individualized suspicion, thereby creating a new category of warrants for regulatory purposes.

Administrative Warrant

A warrant established by Camara, which allows for administrative inspections without individualized suspicion, requiring probable cause based on general safety and regulatory standards for a specific area or industry, rather than suspicion of a particular crime.

Closely Regulated Industry

A legal principle that allows for warrantless administrative inspections in specific industries where the government has a substantial interest in regulation and individuals have a reduced expectation of privacy due to the pervasiveness of the regulation and the history of oversight, as refined by New York v. Berger.

Fourth Amendment

Protects citizens from unreasonable searches and seizures, requiring warrants based on probable cause.

Fourth Amendment Reasoning

The Court emphasized that privacy protection extends to civil and regulatory enforcement, not just criminal contexts.

Special Need

A legal standard allowing for less stringent requirements for searches when significant government interests, beyond normal law enforcement, are involved. This doctrine enables categories of suspicionless or warrant-less searches.

Warrantless Search

A search performed without a warrant, permissible under specific exceptions like administrative inspections in closely regulated industries or under the 'special needs' doctrine.

Probable Cause

A reasonable basis for believing that a crime may have been committed, required for warrants.

New York v. Berger

Created the three-part test for warrantless administrative inspections in closely regulated industries: (1) substantial government interest, (2) warrantless inspections are necessary to further the regulatory scheme, and (3) the statute provides a constitutionally adequate substitute for a warrant by advising the owner of search parameters (certainty and regularity). This established a significant exception to the warrant requirement for these specific businesses.

City of Los Angeles v. Patel

Established that businesses not deemed 'closely regulated' (e.g., hotels) retain a higher expectation of privacy, thus requiring either a warrant for administrative inspections or an opportunity for precompliance judicial review before such inspections without a warrant; it also clarified that a legislative or administrative scheme cannot simply declare an industry 'closely regulated' to bypass Fourth Amendment protections.

Border Search Exception

A categorical exception to the Fourth Amendment's warrant and probable cause requirements, rooted in national sovereignty and the 'special need' to prevent entry of unwanted persons and effects, permitting routine searches of persons and effects at the border without any suspicion.

United States v. Flores-Montano

Reaffirmed the broad scope of the Border Search Exception, establishing that the government's interest in preventing illegal entry and ensuring national security at the border is so compelling that even highly intrusive searches (like vehicle fuel tank searches) are permissible without any individualized suspicion, resting on the 'special need' rationale.

DNA Collection

Established that the routine collection of DNA from individuals arrested for serious offenses is constitutional under the Fourth Amendment, justified by the 'special need' for accurate identification of arrestees (analogous to fingerprinting), which serves legitimate government interests in public safety and crime solving, even without individualized suspicion for the DNA search.

Expectation of Privacy

The degree of privacy individuals can expect in certain situations, diminished in public spaces and some regulated contexts.

Circumstances of Search

The factors that determine the reasonableness of a search, including the location and conditions under which it occurs.

Chandler v. Miller

Established that for suspicionless drug testing programs to be constitutional under the 'special needs' doctrine, the government must demonstrate an actual, present, and substantial 'special need' beyond the normal need for law enforcement; merely symbolic or generalized governmental interests are insufficient to justify intrusion on privacy for positions not directly involving public safety risks.

Safford Unified School District #1 v. Redding

Established that student searches in schools, even under the 'special needs' doctrine, must be reasonably related to the objectives of the search and not excessively intrusive in light of the age and sex of the student and the nature of the infraction. A strip search for generalized suspicion of common prescription drugs was deemed unconstitutional due to its extreme intrusiveness relative to the minor threat.

Vernonia School District 47J v. Acton

Established the constitutionality of suspicionless random drug testing for student athletes under the 'special needs' doctrine. The Court recognized the school's 'special need' to protect children from drug use and deter injuries, especially given the reduced expectation of privacy for athletes and the communal nature of school activities.

City of Ontario v. Quon

Established that a public employer's search of employee electronic communications (text messages) is constitutional if conducted for a legitimate work-related purpose and is reasonable in scope, applying a context-specific 'reasonableness' test rather than requiring a warrant or probable cause. It implicitly distinguished such employer searches from 'special needs' programs focused on generalized societal problems.

Samson v. California

Established that a suspicionless search condition for parolees is constitutional under the Fourth Amendment. The Court recognized the state's 'special need' for effective parole supervision and public safety, combined with the parolees' extremely diminished expectation of privacy, justifying such searches without requiring any individualized suspicion.

Michigan Department of Police v. Sitz

Established the constitutionality of DUI sobriety checkpoints under the 'special needs' doctrine. The Court found that the substantial governmental interest in preventing drunk driving outweighed the minimal intrusion on individual liberty, thus allowing for brief, suspicionless stops at programmatic vehicle checkpoints.

Illinois v. Lidster

Established the constitutionality of information-seeking vehicle checkpoints (e.g., to gather information about a hit-and-run incident). The Court distinguished these from general crime control checkpoints, upholding them under the 'special needs' balancing test, provided they are designed to obtain evidence about a specific crime and are conducted reasonably regarding intrusiveness and effectiveness.

Ferguson v. City of Charleston

Established a critical limitation on the 'special needs' doctrine: a program is unconstitutional if its primary purpose is ultimately indistinguishable from the general interest in crime control. The Court struck down a hospital policy of drug testing pregnant women and reporting positive results to law enforcement because the program's immediate objective was criminal investigation, not patient care, thus failing the 'special needs' test.
