Fourth Amendment: Exclusionary Rule - Fruit of the Poisonous Tree - Exceptions
- independent source: later obtained it independently through activities untainted by the initial illegality
- inevitable discovery: would have eventually or inevitably discovered it by other means that are untainted

Fifth Amendment
individuals have a right against coercive or involuntary confessions conducted by gov’t-authorized personnel.
Any evidence obtained through gov’t conduct that violated the individual’s 14th amendment, 5th amendment, or Miranda rights will be suppressed.
Fifth Amendment: Violation
- evidence at issue is a testimonial statement made to a gov’t-authorized personnel and
- defendant’s statement was coerced
Miranda Rights: Violation
- defendant was subjected to a custodial interrogation and
- (a) defendant was never read Miranda rights; or (b) defendant was read Miranda rights and invoked them but the questioning continued.
Testimonial Statements
oral and written communications that explicitly or implicitly convey or disclose factual information.
Nontestimonial Evidence
fingerprints, blood samples, voice exemplars, handwriting samples, tax documents, and documents that are required to be kept by law and that have a primarily regulatory purpose
Fifth Amendment / Miranda: Gov’t Conduct
5th Amendment does not apply if a private citizen is acting at the direction of a gov’t personnel and the suspect does not know of the relationship between the private citizen and gov’t
Coerced Confession
Courts examine the totality of the circumstances to determine whether a confession was coerced or compelled using two factors:
- physical or psychological pressure (length, deprivation of food or water, false friends)
- defendant’s specific characteristics and known vulnerabilities (age, education)
Basic deception, leading questions, and vague promises of leniency are not coercive on their own.
Can compel incriminating testimony by granting the witness immunity from prosecution.
Miranda Rights Requirements
suspect must be read Miranda rights if the suspect is:
- in custody and
- subject to interrogation unless
- a public-safety exception applies
Miranda Rights: Custody
person is in custody if the person is arrested or deprived of freedom in a significant way. Courts analyze whether:
- reasonable person would have felt able to terminate the interrogation and leave and
- environment has the same inherently coercive pressures as a police station questioning.
Miranda Rights: Interrogation
occurs when a police officer
- asks express questions or
- uses words or actions that the officer should know are reasonably likely to elicit an incriminating response
Voluntary statements and routine booking questions are not a result of an interrogation.
Giving Miranda Rights
police must tell suspect that
- she has a right to remain silent
- anything she says can and will be used against her
- she has a right to counsel during questioning
- if she is indigent, counsel will be provided
Waiving Miranda Rights
must be made knowingly and voluntarily based on the totality of the circumstances. If warning given and understood, defendant’s subsequent uncoerced statement establishes implied waiver.
Invoking Miranda Rights Generally
Must be unambiguous and unequivocal. Merely suggesting that the suspect might want an attorney is not a valid invocation. Once invoked, questioning must stop.
Invoking Miranda Rights - Right to Counsel
Questioning must stop until counsel is provided and physically present.
Police can attempt to reinitiate questioning if they wait at least 14 days and give the suspect new Miranda warnings.
Invoking Miranda Rights: Right to Remain Silent
can reinitiate questioning only after honoring the suspect’s invocation. Three factors to determine if second interrogation valid:
- length of time passed between interrogations
- whether second interrogation involved a different crime
- whether new warnings were read
Suspect can reinitiate a conversation anytime with the police
Fifth Amendment: Exclusionary Rule
evidence is tainted and inadmissible if it was acquired through an involuntary confession but derivative evidence is not excluded because of Miranda violations
Sixth Amendment
attaches once formal proceedings have commenced against a suspect (indictment):
- suspect must be represented by counsel during any critical stage of prosecution
- police and prosecutor cannot interrogate defendant without a lawyer present
OFFENSE-SPECIFIC: applies only to interrogations for crimes with which defendant charged (can interrogate about separate crimes)
Sixth Amendment: Critical Stages
lineups, interrogations, plea bargaining proceedings, preliminary hearings, trials, sentencing, and the first level of appeals.
NOT photo arrays, fingerprint matching, and voice identifications.
Sixth Amendment Applicability
applies to interrogations for crimes with which the defendant has been charged but police can interrogate the defendant about a separate crime.
Undercover informants cannot be used to deliberately elicit responses related to crime in question BUT can merely listen to a defendant’s incriminating statements.
Sixth Amendment: Remedy
if not afforded right to counsel at trial / during plea-bargaining proceeding, subsequent conviction is reversed.
If violation led to incriminating evidence / testimony, exclusionary rule and exceptions apply.
If identification procedure arranged by law enforcement and violates due process, excluded from evidence at trial.
Sixth Amendment: Effective Assistance of Counsel
right to counsel includes effective representation in critical stages.
Ineffective if:
- deficient based on objective standard of reasonableness AND
- defendant suffers prejudice as a result of deficiency.
Defendant may also have claim if actual COI adversely affected attorney’s performance.
Sixth Amendment: Right to Choose Counsel
if defendant has financial means and no issues of competency or COI, defendant has right to choose counsel
Sixth Amendment: Waiver
must be made knowingly and voluntarily based on totality of circumstances
Sixth Amendment: Pro Se
Defendant can represent himself if he makes the decision intelligently and knowingly
Lineups or Showups
due process requires these to be fair under the totality of the circumstances (not unnecessarily suggestive; don’t create risk of mistaken identification). Factors:
- witness’s opportunity to view the perpetrator at the time of the crime
- witness’s degree of attention paid to the perpetrator at the time of the crime
- degree to which witness’s prior description of the perpetrator (if any) matches the defendant
- witness’s level of certainty as demonstrated at the identification and
- length of time between the crime and the identification
Photo Identification
must be fair to the suspect under the totality of the circumstances
Fair Trial: Rights
- jury trial with at least six jurors composed of a fair cross-section of the relevant community if the charge carries a possible sentence of more than 6 mos. imprisonment
- impartial judge with no close personal or financial involvement in the case
- speedy and public trial
- effective counsel
- introduce evidence at trial to prove defendant did not commit the crime
- confront witnesses
- proper conduct by the prosecutor
Jury Trial
all verdicts in criminal cases must be unanimous, except jury’s determination of whether to recommend that judge impose the death penalty in the penalty phase of a capital case
Fair Trial: Fair Cross-Section
to establish prima facie violation, defendant must prove that:
- there was a group qualifying as distinctive
- the group was not fairly and reasonably represented in the jury venire and
- systematic exclusion in the jury-selection process accounted for the underrepresentation
Exclusion of Jurors
- can challenge for cause (bias, views on capital punish, racial prejudice if race involved) - UNLIMITED NUMBER.
- can exercise peremptory challenges (any reason not based on race or gender). If defendant thinks unconstitutional, prosecutor must provide neutral explanation. Mistrial not required if trial court made good-faith error in denying peremptory challenge out of concern that it was discriminatory.
Jury Tampering
person improperly coerces or communicates with a juror.
Can warrant a mistrial.
Competency to Stand Trial
must be competent before standing trial - look at mental state at that time, not when crime committed.
Must fully understand nature and significance of trial proceedings. Trial judge, with assistance of mental health professionals, decides whether competent.
Judge must raise the issue if evidence that defendant is not competent, even if defendant represented by counsel.
Guilty Plea
Defendant has right to enter guilty plea but it must be made voluntarily, knowingly, and intelligently.
Voluntarily = without coercion
Knowingly and Intelligently = fully aware of nature of charges and consequences of pleading guilty
Double Jeopardy
protected against second prosecution for same offense, regardless of whether there was an acquittal or conviction in first prosecution.
would bar subsequent prosecution for a lesser include offense when a defendant was convicted of the serious offense
No Double Jeopardy
gov’t can bring subsequent civil case against defendant that arises out of the same conduct.
Prosecutions by different sovereigns, even for same conduct, not barred (federal and court are different sovereigns)
Only protects successive prosecutions of same offense so if element in each offense is different, no double jeopardy.
Double Jeopardy Requirements
attaches after first witness sworn in (bench trial) or after entire jury empaneled and sworn in (jury trial).
If case dismissed prior to swearing in, no double jeopardy protection.
Eighth Amendment
prevents cruel and unusual punishment (i.e., barbaric penalties or punishment that shocks public morality, such as torture or linger-death punishments)
Cruel and Unusual Punishment Factors
- nature of the crime
- severity of the penalty
- sentences of similarly situated defendants
Cruel and Unusual Punishment: Capital Punishment
considered disproportionate penalty for most crimes other than homicide
Cruel and Unusual Punishment: Juvenile
persons under the age of 18 at time they committed the crime may not be executed or sentenced to life in prison without parole for a nonhomicide crime
Burden of Proof: Constitutional Protection
due process requires that criminal defendants be afforded.a presumption of innocence.
Gov’t must prove all elements of the crime beyond a reasonable doubt
Beyond a Reasonable Doubt
very high standard of proof that requires some level of certainty or firmness.
Burden of Proof: Affirmative Defenses
defendant bears burden of production and proof on an affirmative defense.
Must prove by preponderance of the evidence.
If defendant raises a plausible basis for defense, gov’t must disprove beyond a reasonable doubt.
Appeal and Error: Trial Judge Rulings
harmless error: will not reverse improper ruling unless substantial risk that error affected outcome.
Some constitutional violations are per se prejudicial and require reversal
- detail of counsel during trial
- denial of defendant’s right to a public trial
- constitutional violations in jury selection
- constitutionally deficient jury instructions on reasonable doubt standard
- biased trial judge
Appeal and Error: Jury Verdicts
Sufficiency of the evidence: conviction affirmed provided that reasonable juror could have found defendant committed all required elements beyond a reasonable doubt.
Views all evidence in light most favorable to prosecution.
Appeal and Error: Judge Fact-Finding
Clearly erroneous: if judge sat as trier of fact or imposed sentence, will not revise unless decision was unsupported by substantial, credible evidence in the record
Habeas Corpus
convicted inmate can file petition for writ of habeas corpus challenging lawfulness of detention or imprisonment on jurisdictional or constitutional grounds.
Does not address question of inmate’s guilt or innocence but it is a post-conviction remedy requesting the court to order immediate release.
Habeas Corpus Limitations
Congress has decreased statute of limitations to one year, prohibited successive filings, required exhaustion of remedies, and limited the grounds on which relief may be granted.
