why is a person allowed to lie in court and get away with it? In a court of law, the defendant can tell as much lies as she wants in order to vindicate herself of the charges. But if the court finds them guilty, the false explanations that the person had given are not revisited. Why is this so? Even if a person is doing so to save her skin, shouldn't giving false testimonies in court be regarded as a crime after the person has been proven guilty?
I don't believe your premise is necessarily true. As the Supreme Court has held, a defendant can be prosecuted for perjury after being convicted for another offense at trial: The conviction of Williams, at a former trial, for beating certain victims is not former or double jeopardy. Obviously perjury at a former trial is not the same offense as the substantive offense, under 18 U.S.C. § 242, of depriving a person of constitutional rights under color of law. . . . It would be no service to the administration of justice to enlarge the conception of former jeopardy to afford a defendant immunity from prosecution for perjury while giving testimony in his own defense. United States v. Williams, 341 U.S. 58, 62 (1951) (emphasis added). Now as a practical matter, trying a convicted person for perjury is most likely rare, since the prosecutor has already obtained a conviction for the underlying offense. Starting another prosecution for perjury might be excessive or unnecessary. But that doesn't mean it's categorically prohibited. Note also that perjury by the defendant can be considered by the judge to enhance the defendant's sentence. United States v. Dunnigan, 507 U.S. 87, 96 (1993).
In the US, a person is "within their rights" to invoke the Fifth Amendment, i.e. refuse to self-incriminate. However, the government can give a person immunity from prosecution for offenses having to do with the testimony, in which case he can be compelled to testify. A person is not required to guess about whether they could actually be convicted based on their testimony. It is the privilege of the court (judge) to determine whether a witness has "a reasonable cause to apprehend danger from a direct answer" (Ohio v. Reiner, 532 U.S. 17).
Is truth the ultimate defense to a defamation lawsuit in the USA? Truth is an absolute defense to defamation lawsuits in modern U.S. law (this was not always the case historically) as a matter of constitutional law in every state. In some kinds of defamation lawsuits (but not all kinds of defamation lawsuits), "actual malice" which means knowing falsity or reckless disregard for the truth, must be shown, so even a negligently stated falsehood is not actionable in those special kinds of defamation cases (mostly cases with public figure plaintiffs, media defendants, and/or case involving matters of public concern). Does a defamation defense vary between states? While most aspects of defamation law are mandated by the U.S. Constitution and a shared common law tradition, there are some slight and subtle differences between the states in defamation law, mostly concerning defamation suits by non-public figures against non-media defendants concerning matters that are not a matter of public concern. This impacts whether "actual malice" must be shown and can influence the burden of proof in defamation cases. Statutes of limitation for defamation suits also vary significantly between states. Even if the release of truthful information results in permanent career damage (i.e. loss of job, reputation, etc.) to someone, the truth would protect the author from a defamation lawsuit, correct? Yes. Keep in mind, however, that a defamation lawsuit is a suit for damage to one's reputation caused by a false statement. Sometimes disclosures of truthful information constitute an actionable tort other than defamation, however. For example, there would potentially be a civil action against someone who had signed a non-disclosure agreement for revealing truthfully information that the person sued contractually agreed not to disclose (e.g. the terms of the settlement agreement in a court case with a non-disclosure/confidentiality term, or the recipe for a restaurant's secret sauce that is a trade secret). Similarly, a doctor who revealed confidential patient medical information that was true could be sued. But, usually, in the absence of a particularlized confidentiality duty, truth is an absolute defense.
Chain of custody and testimony in this regard. Say there is a murder victim, with DNA of the suspect under the fingernails and a knife with the suspect's bloody fingerprints stuck in the chest. There would be testimony what happened to the knife. If a paramedic removed it to attempt first aid, the paramedic would testify. So would the officer who bagged it, and the forensic analyst who took the fingerprints. A pathologist would testify if the knife was consistent with the stab wound (a careful pathologist could never swear that the knife was the cause of death, just that it matches). The pathologist would also testify how DNA was collected under the fingernails, and how it was sent to the lab. The defense may claim that the suspect also tried first aid, or that a corrupt cop forced the suspect to hold the knife. The court or jury then draw their conclusions from this and other testimony. Same here. A lifelike picture found on the web proves nothing. A witness who takes the stand to testify that he or she took a certain picture would be more credible. So would a forensic officer who testifies how she or he removed the data from a surveillance camera, checked for common signs of tampering, and then signed a copy of the data with a private key. (The signing shows no third-party tampering after collection, it is not evidence of integrity before that.) Years ago, in germany, there was the case of a bank robber who claimed that a fleeing suspect had handed him a bag of money in the forest and then vanished. &quot;Prove it wasn't so,&quot; he demanded. &quot;You can't. So there is reasonable doubt.&quot; Well, the court found that the statement merely created unreasonable doubt, and the sentence was upheld on appeal.
Hope you have a good prosecutor and a sympathetic judge "They asked repeatedly how much she had to drink ..." Objection: Asked and answered "how she could claim not to remember certain details" Objection: Calls for a conclusion/speculation. The witness is not a brain scientist, she cannot speculate as to why people remember some details and not others. She is testifying as to what she does remember, not as to why she doesn't remember things. "asking if she had not been flirting with him in the days before the incident" Objection: Relevance. Is the defense seriously suggesting that flirtation, if it happened, in the preceding days amounts to consent at the time of the incident? "asked her why she had not chosen a more modest one" Objection: Relevance. Is the defense now suggesting that what the witness wore amounts to consent?
I'm not going to comment on the specifics of this law; rather, I think this question shows a misconception of the way the legal system works in general. Here's the question: do you actually have "legally privileged" material on your phone? If not, what's keeping you from claiming that is that it's not true, and lying to a police officer is a bad idea. And just putting a letter from your lawyer on the phone doesn't mean you've established a legal privilege--attorney-client privilege is not a magic spell, it's a reasonable system of protection that only covers certain communications. The bottom line is: the statute in general, and that clause in particular, were included in the law to protect real, important, and substantial legal right. The courts interpret the law in light of that purpose. If the police officer finds a solution that protects your rights while still carrying out the purpose of the statute, the court will be unlikely to fault him or her. In this case, if you tell the officer that there is a letter from your attorney in a particular folder, the obvious solution is for the officer not to open that folder. Problem solved. In practice, in the United States at least, these cases are dealt with routinely; computers are seized, and attorneys and judges work together to ensure that privilege is protected while still allowing reasonable access to seized materials. I would imagine the same is true in the U.K. The bottom line is: the law is not a game, and technical "gotchas" are rarely effective. Common law systems allow judges enough leeway to avoid this sort of pointless technicality.
If you have something to say, you should have said it before now When a judge is about to hand down a decision the case is all but over. Just like figure skating at the Olympics, the points are scored even if nobody but the judges know what they are yet. The onus is on the parties to bring forward all the evidence and make all the submissions on the law that they want the judge to consider before and during the hearing. If they didn't then that's their fault and they can't introduce new stuff now. Now, it's not uncommon for a judge to share their thoughts during the hearing or in writing when considering written submissions. This is because their thinking on the law is at variance with what the parties are contending. The plaintiff says the law is X, the defendant says the law is Y, the judge thinks they're both idiots and the law is clearly Z. They will usually call for submissions on this because the judge's role is to decide the dispute between the parties on the evidence the contend -not to impose the judge's interpretation on them; by doing this the parties may relies the judge is right and a lot of the dispute disappears or they may convince the judge that they are wrong (it's not unknown) and move on from a clear agreed position.
There is no prohibition on lying in general. Misrepresentation If you misrepresent a fact and that misrepresentation is a material inducement to someone entering into a contract with you then there are a number of problems that follow: The (mis)representation may become a term of the contract and if not complied with can allow the aggrieved party to either sue for damages or rescind the contract. If the misrepresentation led to the contract being entered into by mistake then the contract is void for mistake The misrepresentation may have become a collateral contract an innocent or negligent misstatement may give rise to the tort of negligent misstatement misrepresentation may put you in breach of trade practices statutes. Fraud If you knowingly tell a lie with the intention of receiving a benefit then this is both the tort and crime of fraud. You receiving employment or your company securing a contract probably qualifies as intending to receive a benefit.
