Exclusionary Rule Flashcards
Exclusionary Rule - Def
All evidence seized in violation of the 4th Amendment is excluded
Physical Evidence and statements as a result are inadmissible.
Mapp v Ohio
4th Amendment
Protects people, papers, houses, and effects
Unreasonable search and seizure
Requires particularized warrants
supported by probable cause
Standing to raise 4th Amendment Challenge

Rakas v. Illinois
Fruit of the Poisonous Tree
evidence, including oral statements, physical objects,
acquired directly or indirectly
from illegal search or seizure
must be excluded.
Wong Sun v. United States
Has limited applicability to Miranda Violations
Admission of evidence previously tainted by the poisonous tree
Exceptions (3)
- obtained from source independent of original illegality
INDEPENDENT SOURCE EXCEPTION - no but-for connection - Evidence that would have been discovered regardless
INEVITABLE DISCOVERY EXCEPTION - must prove it was inevitable - Attenuation - Where evidence with a but-for link to poison tree is so distant from initial illegality that taint from poison is purged from fruit.
Looks at flagrancy of constitutional violation and distance between violation and evidence.
Conditions where D may challenge and affidavit upon which a warrant was issued (3) and Standard by which it is measured.
- Substantial showing affidavit contains false statements
- Statements made intentionally, knowingly, or recklessly disregarding the truth; and
- Magistrate would not have found probable cause but for the false statements.
Failure to prove conditions by a preponderance of the evidence will uphold the warrant as having a substantial basis to issue in the first instance.
Balancing Approach to the Exclusionary Rule
Benefit of Rule is to prevent future violations of law.
Rule precludes use of suppressed evidence in prosecutions case in chief, not for impeachment.
Good Faith Exceptions to the exclusionary rule
- Evidence obtained invalid warrant is admissible if
a reasonably well trained officer would believed warrant was valid.
a. police act in good faith reliance on a facially valid warrant.
b. police rely on valid statute
c. police rely on an officer of a court official rather than a police officer
Where the exclusionary rule does NOT apply
- Police mislead court obtaining a warrant
- magistrate is not neutral or detached
- warrant facially so facially invalid no reasonable police officer would believe warrant was valid
Herring v. United States
Good faith exception and police negligence
Exclusionary rule does not apply to illegal arrests
resulting from isolated negligence
attenuated from the point of arrest.
May apply to evidence resulting from gross or systemic negligence on the part of the police.
Limitations of the Exclusionary Rule
- Not applicable in Grand Jury proceedings
- evidence obtained in reasonable reliance on a valid search warrant issued by a detached, neutral magistrate not subject to rule.
- Evidence excluded by one sovereign may be used in a civil proceedings of another sovereign
- Confessions obtained without giving miranda, were coerced, used for impeachment
- not available in deportation and parole revocation hearings
Procedural and Enforcement Considerations of the Exclusionary Rule
D has a right to a suppression hearing outside of the jury’s presence.
Judge determines as a matter of law admissibility of evidence
Govt has burden of establishing admissibility of evidence by prepond.
D’s testimony may not be used against him at suppression hearing on the substantive issue of guilt
Admission of illegally obtained evidence and reversible error.
Such admission constitutes reversible error unless the error is harmless.
Government must prove that error did not contribute to a conviction beyond a reasonable doubt.
4th Amendment applicability to government action.
4th Amendment applies to government action, not private conduct.
Evidence obtained by a private party acting on his own, not as an agent for the government, which the government seeks to later admit does not trigger 4th amendment protection or the exclusionary rule
Arrest and Detention - General principles
warrants not required for arrests in public.
Non-emergency arrests in home requires a warrant
An unlawful arrest is no defense to a subsequent conviction of the crime charged.
