Exclusionary Rule Flashcards
What is the exclusionary rule?
Judge-made doctrine that prohibits the introduction, at a criminal trial, of evidence obtained in violation of a ∆’s 4th, 5th, or 6th Amendment rights
Scope of the exclusionary rule
Applies to:
illegally obtained evidence
AND
all evidence obtained or derived from exploitation of that evidence (possibly admissible: fruits of statements obtained in violation of Miranda)
Balancing test for whether lower courts should apply exclusionary rule
Rule’s purpose (deterrence of police misconduct)
vs.
Costs (exclusion of probative evidence)
Independent source defense to exclusionary rule?
Evidence is admissible if the prosecution can show that it was obtained from a source independent of original illegality
Attentuation exception to exclusionary rule?
If connection b/w unconstitutional police conduct and evidence is too remote or has been interrupted by some intervening circumstance so that causal link is broken, evidence will not be suppressed
Considerations:
- Temporal proximity b/w unconstitutional conduct and illegal evidence
- Presence of intervening circumstances
- Purpose and flagrancy of the misconduct
Defenses/exceptions to exclusion of tainted evidence
- Independent source
- Attenuation–intervening act or circumstance
- Inevitable discovery
- Live witness testimony, if freely willing to testify, excluding would not deter future illegal conduct
- In-court identifications NEVER excluded as fruit of unlawful detention
- Out-of-court identifications excluded ONLY if unnecessarily suggestive circumstances were arranged by the police
When will the Court consider applying the exclusionary rule to out-of-court identifications?
When the circumstances were unduly suggestive and arranged by the police
When may a grand jury witness refuse to answer grounds on the ground that they are based on evidence from unlawful search and seizure?
ONLY if evidence was obtained in violation of federal wiretapping statute
When does exclusionary rule apply to violations of state law?
Never
What cases are subject to exclusionary rule?
Criminal cases based on violations of Constitution or federal law
What is the good faith exception to the exclusionary rule?
Does not apply when the police arrest or search someone erroneously but in good faith, thinking they are acting pursuant to a valid arrest warrant
A police officer cannot rely on a defective search warrant if:
- Affidavit underlying warrant is so lacking in PC that no reasonable police officer would’ve relied on it
- Warrant is defective on its face
- Police officer or gov official obtaining warrant lied to or misled magistrate; or
- Magistrate has “wholly abandoned his judicial role”
Harmless error test for overturning based on improperly obtained evidence
On appeal, gov must show beyond a reasonable doubt that the admission was harmless
Harmless error standard in habeas corpus proceeding
Petitioner must be released if the error had substantial and injurious effect or influence in determining jury verdict
Burden of proof in motion to suppress
Gov bears burden of establishing admissibility by a preponderance of the evidence
