Exclusionary Rule - Definition
[exclusionary rule]
The Exclusionary Rule prohibits the prosecution from using in its case-in-chief evidence obtained in violation of the defendant’s Fourth, Fifth, or Sixth Amendment rights.
General Exceptions to the Exclusionary Rule
[exclusionary rule]
The exclusionary rule does NOT apply:
- To grand jury proceedings (i.e., the grand jury may base its indictment on illegally seized evidence)
- In civil proceedings, including IRS civil proceedings and immigration hearings
- When the accused claims that the search violated an agency’s internal policies or state law (i.e., the exclusionary rule applies only when the search violates either the U.S. Constitution or a federal statute)
- To parole revocation proceedings
- As a remedy for failure to “knock and announce”
- Where use of the illegally obtained evidence was harmless error
Good Faith Exceptions to the Exclusionary Rule
[exclusionary rule]
- If the police relied in good faith on binding appellate precedent that is later overturned by a Supreme Court decision
- If the police relied in good faith on a statute or ordinance that is later declared unconstitutional
- If the police made a reasonable mistake in interpreting the law (e.g., police officer’s reasonable mistake that a vehicle must have two working brake lights—when only one was required—did not invalidate the stop and subsequent arrest)
- If the police relied in objective good faith on computer information containing clerical errors (e.g., an arrest warrant that had been withdrawn but remained on the computer system due to an error by court personnel)
- If the police relied in objective good faith on a search warrant that is defective
Impeachment exceptions to the exclusionary rule
[exclusionary rule]
Impeachment Exceptions: Evidence excluded under the exclusionary rule may be used for impeachment purposes in the following situations:
- An otherwise voluntary confession that violates Miranda or the Sixth Amendment (and thus would not be admissible in the prosecution’s case-in-chief) may be used to impeach the defendant as a witness, but a truly involuntary confession may not.
- Evidence obtained in an illegal search may be used to impeach the credibility of the defendant as a witness (e.g., if he lies about possession of the evidence), but may not be used to impeach other witnesses
Fruit of the Poisonous Tree Definition
[fruit of the poisonous tree]
A court will exclude not only illegally seized items, but also all evidence derived from exploiting illegally seized items. This doctrine expands the scope of the exclusionary rule.
Fruit of the Poisonous Tree Exceptions
[fruit of the poisonous tree]
The evidence will not be excluded where the government can break the link between the unconstitutional act and the evidence, such as:
- The police had an independent source for obtaining the evidence (e.g., court will not suppress evidence initially discovered during police officers’ illegal entry of private premises, where that evidence was rediscovered during later search pursuant to a valid warrant based on information totally unrelated to initial illegal entry)
- Inevitable discovery (e.g., the police would have found the evidence because it was in a location they planned to search)
- Intervening acts of free will on the part of defendant (e.g., defendant is illegally arrested, but then is released on his own recognizance; a couple of days later, the defendant returns voluntarily to the police station and confesses)
- Attenuation doctrine: intervening circumstances between the unconstitutional police act and discovery of the evidence (e.g., officer lacked reasonable suspicion to initially stop defendant, but officer’s discovery of valid pre-existing arrest warrant attenuated the connection between the unlawful stop and drug-related evidence seized from defendant during search incident to arrest and thus the evidence was admissible)
Locating witnesses as a result of an illegal search
[fruit of the poisonous tree]
If an illegal search enable the police to locate a witness, the witness’ testimony will rarely be excluded as fruit of the poisonous tree
Admissibility of confessions obtained in violation of the 5th or 6th Amendments
[fruit of the poisonous tree]
Confessions obtained in violation of the Fifth or Sixth Amendment are inadmissible as evidence of guilt.
Admissibility of confessions obtained in violation of the 4th Amendment
[fruit of the poisonous tree]
Confessions resulting from an illegal arrest are inadmissible, unless there is a weak link between the illegal police conduct and the challenged evidence.
If a defendant (subject to custodial interrogation) confesses without receiving Miranda warnings and then confesses again after receiving Miranda warnings, is the second confessions tainted by the earlier unlawful confession?
[fruit of the poisonous tree]
- If the “question first, warn later” nature of the questioning was a calculated technique to undermine Miranda, the second confession is probably inadmissible.
- If the “question first, warn later” nature of the questioning was unplanned and inadvertent, the second confession is probably admissible.
Guarantee of the 4th Amendment
[law of arrest]
The Fourth Amendment guarantees the right to be free from unreasonable arrests (i.e., seizures)
Definition of arrest
[law of arrest]
An arrest occurs when a person is taken into custody against his or her will for purposes of criminal prosecution or interrogation. There must be an intentional physical application of force by the police or a submission to an officer’s show of force.
The test is: Would a reasonable person believe that he or she is free to leave?
Requirements for a lawful arrest
[law of arrest]
- A warrant or
2. Probable cause
When warrants are required for arrests
[law of arrest]
Warrant: Arrests are generally not required for felony arrests in public places, but
- Arrest warrants are required for non-emergency arrests (felonies and misdemeanors) of a person in the person’s own home.
- Police may arrest a person in his home (or another person’s home) without a warrant if the police are in hot pursuit of the person or enter the home for emergency assistance.
- An arrest of a person just outside his home (or even in the threshold of the front door of his home) is a “public” arrest that does not require a warrant.
- The police may forcibly enter a person’s home to enforce an arrest warrant only if the police have reason to believe the person is at home at the time of entry. - Arrest warrants are generally required for misdemeanor arrests, unless the misdemeanor was committed in the officer’s “presence.”
- If the police intend to execute an arrest warrant in the home of a third party, the police must have a separate search warrant to search for the subject of the arrest warrant (although the arrestee may lack standing to challenge a warrantless search).
Probable cause
[law of arrest]
The officer must have probable cause to make an arrest. For probable cause to exist, there must be a sufficient likelihood that a crime has occurred and that the arrestee has committed or is committing that crime.
Effect of an illegal arrest
[law of arrest]
An unlawful arrest has no effect on a future prosecution, but evidence that is the fruit of unlawful arrest may be excluded under the exclusionary rule.
An unlawful arrest may also lead to civil liability.
General protection of the 4th Amendment
[law of search and seizure]
The Fourth Amendment guarantees the right to be free from unreasonable searches and seizures.
What must be shown to challenge a search under the 4th Amendment?
[law of search and seizure]
- the search must be the result of state action;
- the person challenging the search (i.e., the criminal defendant) must have standing to challenge the search; and
- ## the person searched must have had a reasonable expectation of privacy in the place searched or the government physically intruded into a constitutionally protected area (of the defendant) for evidence-gathering purposes.If these three elements are present, the search is unconstitutional unless the police had a valid search warrant (or in good faith relied on a defective search warrant) or there is an applicable exception to the warrant requirement
Things included as state action under the 4th Amendment
[law of search and seizure]
The Fourth Amendment applies only to government conduct, which includes searches by:
1. Publicly paid police at all times
2. A private individual acting at the direction of the police
3. Public school officials
—
But does not include private persons (e.g., mom or landlord) or privately paid police (e.g., a store security guard) acting on their own initiative
Standing
[law of search and seizure]
As a general rule, a person may assert the exclusionary rule only for violations of his own constitutional rights. In other words, a person must have “standing” to object to the illegality of a search; standing exists where
- The person owns or has a right to possession of the premises searched (including his or her own body)
- The person lives on premises searched (e.g., roommate, tenant)
- The person is an overnight guest on the premises searched
- The person is in lawful possession and control of a rental car even if he is not listed on the rental agreement
Instances in which standing does not exist
[law of search and seizure]
- Passengers in a car that do not own the car and deny ownership of the property taken from it
- This assumes the car was lawfully stopped—e.g., for a traffic violation; if the stop is unlawful, all occupants have standing to challenge the stop - Persons who do not own or live on the premises searched and who are not overnight guests on the premises
- An individual briefly (not overnight) on the premises
Two types of searches under the 4th Amendment
[law of search and seizure]
To violate the Fourth Amendment
(a) the defendant must have had a reasonable expectation of privacy in the place searched or
(b) the government must have physically intruded into a constitutionally protected area (of the defendant) for evidence-gathering purposes.
Reasonable Expectation of Privacy - where a person has it and 16 instances where a person has no REP
[law of search and seizure]
A person generally has a REP in his or her body (including wallets, purses, etc.), home, the curtilage of the home (i.e., attached garage and a small yard adjacent to the home), and private business premises (e.g., an office locker). But a person has no REP if the item or place searched is public in nature or is held out to the public, such as:
- Sound of a person’s voice (voice exemplar) or look of a person’s face
- Style of a person’s handwriting (handwriting exemplar)
- Items of property the defendant has transferred (sold or given) to a third party
- Telephone numbers dialed (pen register)
- Paint on the outside of a car (scrapings)
- Account records held by a bank or other business (but a person has a REP in cell phone site location information held by a commercial vendor)
- VIN numbers in cars (even if the police must move items to see the number)
- Anything that can be seen across open fields (i.e., outside the curtilage of her home)
- DNA swabs (upon arrest for a serious crime)
- Anything that can be seen or photographed from a fly-over in public airspace (except for thermal imaging of the inside of a house)
- Odors coming from luggage (but not squeezing luggage)
- Odors coming from a vehicle (dog sniffing), as long as the vehicle was lawfully stopped and not held beyond the time necessary to issue a ticket
- Garbage set out to the curb or alley for collection
- Movement of a person or a person’s automobile (including with the use of electronic beepers if placed in the vehicle without committing a trespass)
- Material held out for sale to the public
- Parolees generally waive their REP as a condition of parole and the homes of persons on probation may generally be searched without a warrant.
Examples of physical intrusion searches
[law of search and seizure]
A Fourth Amendment search also occurs if the government physically intrudes into defendant’s constitutionally protected areas (e.g., body, home, curtilage of the home, vehicle) for evidence-gathering purposes, such as
- A dog sniff on the porch of defendant’s home
- A GPS device attached to defendant’s vehicle
- Long-term tracking of a vehicle with a GPS device would also violate defendant’s reasonable expectation of privacy - A satellite-based tracking device worn on defendant’s body
- In addition, wiretapping/eavesdropping requires a warrant, unless one party to the conversation consents to a government monitoring or the conversations are conducted in a reckless fashion so that they are overheard by others.
