15. Privilege Against Self Incrimination
The Fifth Amendment protects an individual from being “compelled in any criminal case to be a witness against himself.”
- The privilege against self-incrimination applies only to persons, not to corporations or organizations.
- The privilege, however, does apply to individuals who could be personally responsible for business, corporate, or organizational activities.
- The privilege applies to police investigations and pretrial proceedings, not just during a criminal trial.
- It also applies to testimony solicited in civil or administrative proceedings if answers would provide a reasonable possibility of incriminating the person in a future criminal prosecution.
- The privilege, however, applies only to testimonial evidence, not to physical evidence like blood samples or handwriting exemplars.
- The defendant in a criminal case waives the privilege by taking the stand. Similarly, any voluntary statements made by an individual to police or others may be used against the individual in a criminal prosecution.
The privilege protects a person from being compelled to be a witness against themselves in a criminal case. The whole game on the exam is knowing exactly where its edges fall: who holds it, where it applies, what it covers, and how it ends.
- 1Who: the privilege belongs to persons, not to corporations or organizations; a company cannot plead it to keep its records from a prosecutor. But an individual who could be personally responsible for business, corporate, or organizational activities keeps the privilege for their own testimony. The line is person versus entity, not business versus personal.
- 2Where: not confined to the witness stand at trial. It reaches police investigations and pretrial proceedings, and testimony solicited in civil or administrative proceedings, so long as a truthful answer would create a reasonable possibility of incriminating the person in a future criminal prosecution.
- 3What: only testimonial evidence, meaning communications that reveal the contents of the person's mind. It does not protect physical evidence.
- 4How it ends: a criminal defendant who takes the stand waives the privilege as to the matters they testify about; you cannot testify in your own defense and then refuse cross-examination. And the privilege guards only against compulsion, so any statement a person makes voluntarily may be used against them. Voluntary is the opposite of compelled, and only the compelled is protected.
The testimonial-versus-physical line is where most questions live. Compelling a person to give a blood sample, a handwriting exemplar, a voice exemplar, or to stand in a lineup is not compelling testimony, because the person is a source of physical characteristics, not a witness against themselves.
Four questions in order: who (persons, not entities, but the individual keeps it even for business acts), where (not just trial: police investigations, pretrial, and civil/administrative proceedings when answers risk a future criminal prosecution), what (only testimonial, never physical), and how it ends (defendant waives by taking the stand; voluntary statements are fair game because only the compelled is protected). The one cue that wins the most questions: blood samples, handwriting and voice exemplars, and lineups are physical, so the privilege does not reach them. If an answer protects physical evidence, eliminate it.
A man is pulled over at a roadside stop on suspicion of driving while intoxicated. An officer asks him to provide a blood sample. He refuses, asserting that forcing him to give blood would make him a witness against himself. The blood is lawfully drawn and the prosecution offers the result at his trial. He moves to exclude it as a violation of his privilege against self-incrimination.
The motion fails; the blood result comes in. Now flip one fact. Suppose instead the officer compels him to answer where he had been drinking and how much, and the answers tend to incriminate him. Those answers are testimonial communications, so the privilege applies and compelled answers could be suppressed. The setting did not change; the testimonial-versus-physical nature of the evidence did, and that is what controls.
An answer that treats physical evidence as protected: it says the privilege bars a compelled blood sample, handwriting or voice exemplar, or lineup appearance, or says producing one makes the person a witness against himself.
The privilege covers only testimonial evidence, the contents of the mind. Physical evidence drawn from the body is never protected.An answer that limits the privilege to trial, or to the period after charges are filed, and therefore denies it during a police investigation, a deposition, or an administrative hearing.
The privilege applies to police investigations, pretrial proceedings, and civil or administrative proceedings when answers risk a future criminal prosecution.An absolute option: the privilege bars ANY incriminating statement, protects the defendant from EVER answering, applies to ANY question, or can NEVER be waived.
The privilege has printed boundaries: only compelled testimonial evidence is protected, and it is waived by taking the stand or by speaking voluntarily.An answer that lets a corporation assert the privilege, conditions it on having a lawyer, or treats a voluntary statement as though it were compelled.
The privilege belongs to persons (an individual keeps it even for business acts), turns on compulsion not on counsel, and never reaches a voluntary statement.A correct yes/no whose because-clause rests on harm, bad motive, or the mere fact that the evidence is incriminating, rather than on whether the evidence was compelled testimonial evidence.
Name the operative reason: compelled testimonial evidence from a person. Incriminating effect alone is not the test.the stem compels someone to produce something that could incriminate them, then asks whether the privilege against self-incrimination applies.
who: a person holds it; a corporation or organization does not, but an individual keeps it even for business or organizational acts.
where: it is not limited to trial; it reaches police investigations, pretrial proceedings, and civil or administrative testimony when a truthful answer risks a future criminal prosecution.
what: this is the pivot, ask whether the compelled item is testimonial (the contents of the mind) or physical (a blood sample, handwriting or voice exemplar, a lineup).
Physical is never protected.
how it ends: a defendant who takes the stand waives it, and a voluntary statement was never compelled, so it comes in.
The instant you see compelled blood, handwriting, or a lineup, the privilege does not apply; the instant you see a compelled answer that reveals what the person knows, it does.
A man was stopped by an officer at a roadside checkpoint who suspected him of driving while impaired. Acting under lawful authority, the officer directed that a sample of the man's blood be drawn for analysis. The man objected, insisting that being forced to supply his blood would turn him into a witness against himself. The sample was drawn anyway, and at the man's later trial the prosecution offered the analysis of the blood. The man moved to exclude the result as a violation of his privilege against self-incrimination.
Should the court admit the blood-analysis result over the man's objection?
A grand jury investigating a closely held company subpoenaed its managing owner to testify about how the company kept its books. Truthful answers about her own role in handling the company's money would tend to expose her to a future criminal prosecution. She asserted the privilege against self-incrimination and declined to answer those questions. The prosecutor argued that because the questions concerned the company's business activities rather than her purely private affairs, the privilege gave her no protection.
Is the prosecutor correct that the owner may not invoke the privilege as to those questions?
A witness was called to give testimony at an administrative licensing hearing. The hearing was not a criminal trial, and no criminal charges had been brought against her. But several of the questions called for answers that, if truthful, would create a reasonable possibility of incriminating her in a future criminal prosecution. When she refused to answer those questions and asserted the privilege against self-incrimination, the agency's lawyer responded that the privilege has no place in an administrative proceeding.
May the witness properly invoke the privilege at the administrative hearing?
Before any officer questioned her or placed her under any pressure, a businesswoman walked into a police station and, on her own initiative, told a detective several details about a transaction that tended to incriminate her. No one had compelled her to speak, and she was free to leave the entire time. The prosecution later sought to introduce her statement at trial. She objected that using her own words against her would violate the privilege against self-incrimination.
May the prosecution use the businesswoman's volunteered statement against her at trial?
At her own criminal trial, a defendant chose to take the witness stand and testify in her own defense about the events on the day in question. When the prosecutor began cross-examining her about those same events, she refused to answer, asserting the privilege against self-incrimination and insisting she could not be compelled to be a witness against herself. The prosecutor asked the court to require her to answer.
Should the court require the defendant to answer the prosecutor's cross-examination questions about the matters she testified to?
