USA: Can a witness take the 5th to avoid perjury? Lawyer Alice is questioning witness Bob. Bob is not on trial, and no one has accused him of a crime. Alice demands Bob answer a particular question with either a "Yes" or a "no." Bob believes that doing so would mislead the court so greatly that he attempts to use a complete sentence, only for Alice to interrupt him and demand the one word answer. In frustration, Bob simply takes the 5th, to avoid what he believes is perjury. What will happen to Bob now that he's taken the 5th? Will he be held in contempt of court, or will the judge be concerned and try to probe further? Assume Bob is unaware of the concept of rebuttal questions. In case the specific fact pattern is required: Bob witnessed Charlie be hit with a baseball bat, which resulted in Charlie knocking over (and breaking) a vase. Alice is asking if Charlie broke the vase. In Bob's mind, a "yes" answer is a lie, the blame lies with the assailant. A "no" answer is a lie, as Charlie's fall did cause the vase to break.
Your ability to assert your Fifth Amendment right against self-incrimination is not limited to cases where you are on trial or have been accused of a crime. Your ability to assert that right is also not an absolute bar against being ordered to testify: if you are given immunity, you can be forced to testify. Alice cannot hold Bob in contempt – only the judge can. Bob can explain to the judge why a simple truthful "yes" or "no" answer is not possible, if he knows how to do that (does he understand the notion of a false presupposition, or unclarity?). He could for example assert truthfully that he does not understand the question (pointing to the distinction between "Charlie's body falling on the vase, causing it to fall and break", and "Charlie acting with apparent intent to break the vase", since it's not patently obvious that the former scenario constitutes "breaking the vase"). However (changing the scenario a bit), he has to understand that if the question is "Did Charlie shoot Delilah?" and the fact is that Ethan forced Charlie to shoot Delilah, saying "No" based on a theory of blame is not reasonably interpreted as truthful testimony. Taking the 5th, without setting forth your basis (not understanding the question) runs the risk that the prosecution will grant immunity from prosecution, and therefore you don't get to avoid answering the question. Immunity covers various things except that it does not cover prosecution for perjurious testimony. See US v. Apfelbaum, 445 U.S. 115: the Fifth Amendment does not prevent the use of respondent's immunized testimony at his trial for false swearing because, at the time he was granted immunity, the privilege would not have protected him against false testimony that he later might decide to give. Immunity is conferred under the control of some applicable statutory law, such as 18 USC 6002 which says that no testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information) may be used against the witness in any criminal case, except a prosecution for perjury, giving a false statement, or otherwise failing to comply with the order.
The parties are generally entitled to present their case as they see fit, as long as they stay within the rules of evidence. If they want a straight yes or no, the court will often require the witness to provide one, which keeps lawyers happy, makes the answers clear for the jury, and limits the parties' grounds for appeal. If a yes or no answer is not as accurate as a more qualified answer, the other lawyer would typically have an opportunity to invite the witness to provide a fuller answer on redirect. If a yes or no answer is inappropriate because of assumption embedded in the question -- as in your &quot;beating his wife and kids&quot; example -- the question should quickly elicit an objection from the defense attorney, who would note that the question lacks foundation or assumes facts not in evidence. Assuming there isn't any evidence of domestic violence, the court should sustain the objection, in which case the witness would not need to answer at all.
united-states Witnesses are generally confined to giving testimony from their own personal memory; most of the time, they can't read a statement into the record or just tell the jury to go look at some other piece of evidence. But this creates problems when a witness knows an important fact but doesn't remember it when she takes the stand. Maybe she counted exactly how much money she stuffed in the robber's bag as she was doing it, and she wrote it down as soon as he fled, but a year later, she can't remember that it was $93,736.45. But the prosecutor isn't allowed to just give the witness a stack of evidence and let her go hunting through the documents to answer each question. Instead,he goes through the &quot;Do you remember&quot; colloquy to lay the necessary foundation to refresh the witness's memory, as contemplated by Rule 612, which then also triggers certain rights for the opposing party with respect to the document used to refresh the witness's memory.
This is largely congruent with* the doctrine of laches. The basic idea, under common law, is that you can lose rights by failing to assert them. This is generally important for many reasons, but specifically in the case of appeals: The argument should have been brought before the trial court. Justice is not a game, but it's important to recognize that the party trying to raise the argument had an opportunity to do so already. They have given up their right to raise this argument, and extending them the privilege of doing so is (for the following reasons) not good for the system. Courts of appeals are typically not well-equipped to evaluate factual evidence. It is not their area of expertise. Witnesses or evidence may be less available. It's just not practical to try to adjudicate factual issues on appeal, most of the time. If anyone could get an appeal by bringing new factual arguments, then everyone would do that. You'd bring your strongest argument before the district court, and then if that fails, bring the second strongest before the circuit court. That way, you get an extra trial. This is inefficient. Allowing factual arguments on appeal would encourage attorneys and their clients to strategically bring different facts before different courts. This kind of forum-shopping is harmful because it has little to do with who has the stronger overall case, and more to do with who has the better lawyer. * "Congruent with" is not the same as "an instance of"; this rule is not formally an application of laches. It just happens to share the same justification.
Bob should certainly expect to be impeached by whichever side his testimony injures. Their attorney will confront him with the transcript of his previous testimony, and likely read it out loud for the jury to hear, and force him to acknowledge that he said something different before. This is pretty standard trial tactics. Bob would not be treated as formally admitting that he committed perjury, though I think it's fair to say that he has effectively made that admission. One side will treat him as having lied the first time; the other will treat him as lying now. It's possible that he will have some explanation for the discrepancy -- he was high, he has memory problems, he misunderstood the question -- but in your hypothetical, the explanation would have to be pretty amazing to justify such a complete reversal.
The defense lawyer has the duty to do the best for his client. The client will be convicted if he or she is guilty beyond reasonable doubt. If the lawyer can create a reasonable doubt and manages to free his client then he has done a good job. So yes, if the lawyer knows that some other person might have committed the crime, to the degree that it creates reasonable doubt, then the lawyer must raise this. Of course if it turns out that there is just some phantasist making wild accusations, that might not be helpful.
If someone testifying before congress refuses to respond to appropriate questions (questions within the scope of the congressional inquiry), that person can be cited for contempt of Congress. One way to avoid this is if the witness can invoke the Fifth Amendment privilege against self-incrimination. That says that a person may not be compelled to be a witness against himself (or herself) in a criminal case, and has been interpreted to mean that if testimony might in future be used against the witness in a criminal case, it cannot be required, even if the current occasion is not a criminal case. However, if a person has been granted immunity in a particular matter, no testimony can be used against the person in a criminal case on that matter, and so there is no Fifth Amendment privilege not to testify on that matter. This applies to testimony before a court as well as before Congress. The grant of immunity must be at least as comprehensive as the refusal to testify would have been, or the privilege remains. Therefore, if a person has been granted immunity on a subject, that person cannot refuse to testify before Congress by invoking the Fifth Amendment. If the person does refuse, s/he can be cited for contempt of Congress. However, the person can raise a claim that the inquiry was not a proper one, for example because the subject was not a proper one fo Congressional inquiry, or that the Committee was not properly authorized. If the court upholds such a claim, the person will not be convicted of contempt. Also, while Congress can issue a citation, the Justice Department is not required to prosecute the person, and may choose to let the issue drop. Or the court might not convict on some other ground. And of course Congress (or one house of it) has to vote to issue the citation, which it might decide not to do, for political reasons, or indeed for any reason at all. So a grant of immunity alone is not enough to say that testimony will be compelled, but it is a significant step towards such compulsion. Note that under Murphy v. Waterfront Comm'n, 378 U. S. 52 (1964), a state grant of immunity also bars Federal use of the compelled testimony or its fruits, and under Kastigar v. United States, 406 U.S. 441 (1972) a Federal grant of immunity bars state use of the compelled testimony or its fruits. See also This Justia essay on "the Power to Compel Testimony" which covers the whole subject with multiple case citations.
No, a defendant may not remain silent on cross-examination. Witnesses who voluntarily testify in their own defense are subject to cross-examination on that testimony. In Fitzpatrick v. United States, 178 U.S. 304, (1900), a murder defendant testified that he was at two bars and then his cabin the night of the crime. The trial court held that having waived his Fifth Amendment right to remain silent, the defendant was subject to cross examination about what he was wearing that night, his connections to a co-defendant, the co-defendant's clothes, and who else was at the cabin with him. The Supreme Court affirmed the conviction, holding that if a defendant voluntary makes a statement about the crime at trial, the prosecution may cross-examine him with as much latitude as it would have with any other witness: The witness having sworn to an alibi, it was perfectly competent for the government to cross-examine him as to every fact which had a bearing upon his whereabouts upon the night of the murder, and as to what he did and the persons with whom he associated that night. Indeed, we know of no reason why an accused person, who takes the stand as a witness, should not be subject to cross-examination as other witnesses are. Fitzpatrick v. United States, 178 U.S. 304, 315 (1900).
