Does a witness admit perjury by testifying a different story on retrial? Bob was a witness in a trial. That trial was later declared a mistrial and a new one was ordered. When taking the witness stand again, Bob tells a whole different story, inconsistent or directly opposite to what he testified in the original trial. Can his original testimony be even referred to in the new cross-examination? Or is that rendered inadmissible due to the whole original trial being a nullity? Does he effectively admit committing perjury by claiming he is saying the truth now, inference being that he was lying under oath previously? (Any common law jurisdiction)
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.
There are instances when the testimony may still be admitted. For example, a deposition may be admitted at trial either for impeaching or when a witness cannot attend, which involves the circumstance of death (FRCP 32(a)(4)(a)). Additionally, regarding hearsay, there are numerous exceptions. My Evidence professor said in class "If you cannot find a way to get evidence around a hearsay objection, you are not trying hard enough." One such hearsay exception states in the committee notes: Accordingly, the committee has amended rule 803(8) to refer to the provision of [proposed] rule 804(b)(5) [deleted], which allows the admission of such reports, records or other statements where the police officer or other law enforcement officer is unavailable because of death, then existing physical or mental illness or infirmity, or not being successfully subject to legal process.
So I'm fascinated with the OJ trial and I've read a ton about it. I'll try to answer your question both accepting your premise as true, and then also going into what actually happened. First of all, jury nullification cannot be overturned in the US. The double jeopardy clause forbids it. This is such a powerful tool, in fact, that there are strict rules that prevent defense lawyers from mentioning or even hinting at jury nullification, in front of the jury, in almost all circumstances. It doesn't mean D is safe from all legal liability. OJ, obviously, was found liable in the civil trial. Sometimes other jurisdictions can prosecute. For example, after the officers in the Rodney King beating were acquitted in state court, the federal government got them for violating federal hate crime statutes. Second, looking at your premise. If jurors think D is guilty, but also being framed, that's not necessarily jury nullification. Remember, a criminal defendant must be proved guilty beyond a reasonable doubt. That means that 'probably guilty' means 'not guilty.' That said, there may be times when a jury is convinced beyond a reasonable doubt of a defendant's guilt, but is so disgusted by the police tactics used in the case that they acquit. This would be jury nullification. What actually happened in the OJ case: Mark Fuhrman perjured himself on the stand. He lied and said he'd never said the N word, and the defense produced tapes of him saying it a ton. The defense recalled him to the stand. Because perjury is a serious crime, this time he came in with his own defense lawyer, and did nothing but take the fifth on the stand. In a genius move, OJ's defense team asked him whether he planted any evidence in the OJ case. He didn't deny it, instead he took the fifth (again, as he was doing to every question). This was enough to sow reasonable doubt about OJ's guilt based on the evidence in that trial (there's obviously no actual doubt, in real life, that he's guilty). So, what actually happened wasn't jury nullification.
I'd imagine that testimony from the defendant is rare enough that in the majority of cases, prosecutors do not meaningfully prepare for a cross examination. To the extent they do, I'd expect the preparation is similar to that for basically any other witness. So I wouldn't expect complicated flowcharts, because the general rule at trial is that you only ask questions whose answers are both known and helpful. So if I need to place the defendant at the OK Corral at 3 p.m., I'm only going to ask him where he was at 3 p.m. if I have evidence showing that fact is true -- maybe he gave a written statement to the sheriff, maybe he posed for a daguerrotype, whatever. I expect him to deny it, so I don't ask the question unless I have evidence more convincing than his denial. In this way, a defendant -- like any hostile witness -- is used less to provide any facts of their own, but rather as an involuntary narrator of my own story, authenticating evidence and validating the facts consistent with my theory of the case.
The jury would never hear the recording The recording and its provenience would be provided to the prosecution who would, rightly, have issues with its admissibility. The defence and prosecution would make submissions on this to the judge, normally well before the trial date and the empaneling of the jury. If the recording had genuinely emerged during the trial, such submissions would be made without the jury seeing them. The submissions would typically be in writing rather than verbal. If the judge decided the evidence was inadmissible the jury would never see it and never know of its existence. If the jury somehow found out about it anyway, this would be grounds for an immediate mistrial and we would start again with a new jury. Illegally obtained evidence is not automatically inadmissible Hong Kong is not the United States - admitting or excluding illegally obtained evidence is at the discretion of the judge based on where the interests of overall justice are best served. In any event, the absolute prohibition in the US applies only to prosecution evidence - evidence illegally obtained by the defence is subject to the same rules as in Hong Kong; the judge decides.
maryland I think not In Maryland (a typical state on such issues) the relevant law is Section 9-101 - Perjury, which reads in pertinent part: a) Prohibited.- A person may not willfully and falsely make an oath or affirmation as to a material fact: (1) if the false swearing is perjury at common law; (2) in an affidavit required by any state, federal, or local law; (3) in an affidavit made to induce a court or officer to pass an account or claim; (4) in an affidavit required by any state, federal, or local government or governmental official with legal authority to require the issuance of an affidavit; or (5) in an affidavit or affirmation made under the Maryland Rules. A statement of intended future conduct is probably not a &quot;fact&quot; as required by this section. Classic perjury, that is making a false statement during testimony in an actual court session is covered by subsection (a)(1), which makes it relevant what was considered perjury at common law. In Volume 2 of A Treatise on the Criminal Law of the United States By Francis Wharton (Kay and brother, 1874) section 2226 says: At Common law perjury cannot be committed in an official oath, as far as such oath touches future conduct. On page 321 of The Law and Higher Education: a Casebook by John Seiler Brubacher (Fairleigh Dickinson University Press, 1971) appears the phrase: ... a promise of future conduct, the breach of which would not support a conviction for perjury This was in reference to the 1931 US law mandating a loyalty oath, and why such a law violates due process. Also relevant is the article &quot;When Is a False Statement Perjury?&quot; by the MoloLamken law firm. This discusses the federal perjury lws: 18 U.S.C. §1621 and 18 U.S.C. §1623. There is no mention of false sttements about future conduct.
united-states Perjury only applies to someone who actually does testify and is untruthful. A person who refuses to testify at all, when ordered to do so by a subpoena, is committing contempt of court. It is possible, in principle, for the court to order them jailed indefinitely until they do testify (civil contempt). It is also possible for them to be prosecuted criminally afterward (criminal contempt).
You can't guarantee a juror's disregard, and some attorneys might utilize the "once it's said, it can't be unsaid" strategy because they know that the jury will still keep it in the back of their mind even though they've been told to ignore it. But there are checks and balances to prevent a remark having an impact on the final decision: Jury deliberation. Chances are, not all jurors will keep the thought in their mind. The jury gets a chance to deliberate after the case has been presented, and it's very easy for other jurors in the deliberation room to point out they're ignoring that piece of information and not let it influence the final decision. Declaring a mistrial. A mistrial is fully at the judge's discretion, but generally anything that affects the jury's ability to remain impartial can result in a mistrial being declared (for example, if an attorney deliberately said something outrageous to influence the jury when they knew it would be withdrawn, the judge will likely declare a mistrial without much thought). Once a mistrial is declared, the case will be postponed and a brand new jury will be selected that hasn't heard the previous remarks - easiest way to erase it from their minds is to not use their minds.
