A search or seizure occurs when government officials violate a person's reasonable expectation of privacy or physically intrude on protected areas without a warrant supported by probable cause or a recognized exception.

How it applies
Common Examples
6
Warrantless Home Entry
Scott Summers returns home to find officers inside his residence examining his papers without a warrant. The officers had no probable cause or exigent circumstances. The evidence they seize is subject to suppression because the entry violated the Fourth Amendment protection against unreasonable searches and seizures.
State Court Suppression
Skylar Sullivan is prosecuted in state court after officers seize drugs from her car during an unlawful stop. The state seeks to introduce the evidence despite the constitutional violation. The exclusionary rule bars its use to deter future police misconduct.

Restatements
Sophia Singh purchases property and later discovers an undisclosed lien that a title search missed. The insurer refuses coverage under the policy exclusions. The dispute centers on whether the title search adequately protected against defects in the recorded chain of title.
Tainted Confession Chain
Santiago Sanchez gives a statement after an illegal arrest. Officers later obtain a second statement following proper warnings. The second statement is admissible only if the taint from the initial seizure has dissipated through intervening circumstances.
Garbage Can Search
Sierra Santos places personal documents in her trash can at the curb. Officers retrieve the documents without a warrant. The search is lawful because Santos abandoned any reasonable expectation of privacy in items left for collection.
Housing Inspection Warrant
Steven Silva refuses entry to housing inspectors seeking to check code compliance. The inspectors obtain an administrative warrant based on an area inspection plan. The warrant satisfies the Fourth Amendment because it is supported by reasonable legislative standards rather than individualized probable cause.

Common questions
Frequently Asked
4
Does the exclusionary rule apply in state criminal proceedings?+
Yes. Evidence obtained through an unconstitutional search or seizure is inadmissible in state court under the Fourteenth Amendment's Due Process Clause. The rule deters police misconduct and applies equally in state and federal courts.
Supporting sources
What test determines whether government conduct constitutes a search?+
A search occurs when government officials violate a person's reasonable expectation of privacy. The two-part inquiry asks first whether the person exhibited an actual expectation of privacy and second whether society recognizes that expectation as reasonable.
Supporting sources
When may evidence be admitted despite an initial constitutional violation?+
Evidence is admissible if obtained by means sufficiently distinguishable from the primary illegality so that the connection has become attenuated. Courts consider temporal proximity, intervening circumstances, and the flagrancy of official misconduct.
Supporting sources
Do administrative inspections require traditional probable cause?+
No. Area-wide inspection programs may be authorized by warrants based on reasonable legislative or administrative standards rather than individualized suspicion. The warrant ensures the inspection is reasonable and limits official discretion.
