What rule, law or principle mandates police to separate those making statements in a police report to prevent adjustments of statements? Say person A makes a police report, and person B is present to overhear the statement of A. The police knows the fact B overhears the statement of A. A makes false statements (negligent, reckless, willful, doesn't matter). B then makes a statement, the same false statement as A. The police knows the two statements were false, but this is probably also irrelevant. Is there U.S. common law name of the rule or principle to separate those making the statements? Is there a name for a prohibition to prevent this sort of &quot;adjustment&quot; or even unintentional, subconscious bias? Is it regulated by statute in California? What jurisprudence exist to mandate the proper police conduct or prohibit the contrary? Some self-search: To assert probable cause the police must be able to provide “&quot;reliable information from a credible person” (Aguilar v. Texas (1964) 378 U.S. 108, 119) The importance of credible witnesses shows in this case: &quot;Evidence can be &quot;used to impeach&quot; a witness even if the evidence is not itself admissible, even to impeach. For example, if Haws' notes record Elliott's hearsay reports of Dr. Brady's hearsay statements, then the notes themselves would not be admissible, even to impeach Dr. Brady. But if Dr. Brady's hearsay statements, reflected in the notes, contradict his in-court testimony, then the notes could be used to impeach Dr. Brady by leading the defense team to call Elliott to testify regarding Dr. Brady's prior inconsistent statements, which, as such, would not be hearsay.&quot; (Paradis v. Arave (9th Cir. 2001) 240 F.3d 1169, 1179) On &quot;mutual reinforcement of opinion&quot;: &quot;Furthermore, it appears the identification here was a product of &quot;mutual reinforcement of opinion&quot; among the witnesses ( Clemons v. United States (D.C. Cir. 1968) 408 F.2d 1230, 1241, 1245 fn. 16), and it is unclear from the record whether or not the girls could have independently identified the defendant. It is clear they did not do so. Furthermore, they were unable to do so at the ensuing lineup.&quot; (People v. Nation (1980) 26 Cal.3d 169, 180)
None No law requires police to keep people apart when making statements. Doing so is good police practice. In some police organizations internal regulations or procedures may specify that officers should do so. But those are not laws. In some cases witnesses may have had a chance to confer and agree on a story before police arrive, the police cannot prevent that. The trier of fact can take into account that witnesses had a chanc to agree on a false story.
Despite the lengthy background, the only question seems to be: Can a police officer lie about a consequence of a traffic violation they charge you with? As a matter of constitutional law in the United States, that answer is generally &quot;yes.&quot; States can impose more limitations if they like. Only a small minority of states actually do so. Incidentally, an attorney, such as a deputy district attorney, is not allowed to lie about the consequences of a traffic violation, or anything else (even in extreme circumstances like a hostage situation). This violates the rules of professional conduct applicable to all attorneys. This sounds like a classic &quot;driving while black&quot; situation and is probably involves unconstitutional discrimination by a government official, although proving that in an individual case is virtually impossible.
There are four criteria used today in the United States: The statement was false, but was claimed as true. The statement must have been made to a third, previously uninvolved party. The statement must have been made by the accused party. The statement caused harm. The first (and very important) criterion was discussed in New York Times v. Sullivan, where it was ruled that A State cannot, under the First and Fourteenth Amendments, award damages to a public official for defamatory falsehood relating to his official conduct unless he proves &quot;actual malice&quot; -- that the statement was made with knowledge of its falsity or with reckless disregard of whether it was true or false. Pp. 265-292. (c) Factual error, content defamatory of official reputation, or both, are insufficient to warrant an award of damages for false statements unless &quot;actual malice&quot; -- knowledge that statements are false or in reckless disregard of the truth -- is alleged and proved. Pp. 279-283. Quoting Wikipedia and Justice Black, The Court held that a public official suing for defamation must prove that the statement in question was made with actual malice. In this context, the phrase refers to knowledge or reckless lack of investigation, rather than its ordinary meaning of malicious intent. In his concurring opinion, Justice Black explained that &quot;'[m]alice,' even as defined by the Court, is an elusive, abstract concept, hard to prove and hard to disprove. The requirement that malice be proved provides at best an evanescent protection for the right critically to discuss public affairs and certainly does not measure up to the sturdy safeguard embodied in the First Amendment.&quot; New York Times v. Sullivan is regarded as one of the most - of not the most - important defamation cases of the century. It was argued in 1964. If the case you discuss - which I haven't been able to find - occurred after to the ruling, then it could have been dismissed, because A did not intend it as malicious in the sense of defamation (and did not claim it was true), though it was almost certainly meant as an insult. Had this case occurred prior to New York Times v. Sullivan, things might have been different. Non-public officials Things are different for private officials. Those who are not classified as public figures are considered private figures. To support a claim for defamation, in most states a private figure need only show negligence by the publisher, a much lower standard than &quot;actual malice.&quot; Some states, however, impose a higher standard on private figures, especially if the statement concerns a matter of public importance. You should review your state's specific law in the State Law: Defamation section of this guide for more information. Note: There are differences between defamation, libel, and slander; a quick overview is given here: &quot;Generally speaking, defamation is the issuance of a false statement about another person, which causes that person to suffer harm. Slander involves the making of defamatory statements by a transitory (non-fixed) representation, usually an oral (spoken) representation. Libel involves the making of defamatory statements in a printed or fixed medium, such as a magazine or newspaper.&quot;
You have to deconstruct the question on a country by country basis. In the US legal system, the question presupposes something incorrect, that there are &quot;investigators&quot; who play a rule in legal system, and their job is to determine guilt vs. innocence. That is something determined by the &quot;finder of fact&quot;, typically the jury (it could be a judge, when you have a bench trial). The finder of fact may take into consideration testimony provided by a witness, and it is possible that a witness is an expert in some relevant area, who might attest to the significance of a claimed piece of evidence. The expert cannot testify on the question of guilt. For example, a DNA sample might be admitted as evidence that the defendant was present in certain circumstances, which could reasonably lead the finders of fact to conclude that the defendant did strike the victim. A DNA sample cannot testify, therefore some expert must testify about the significance of the sample, specifically whether the sample &quot;might have&quot; come from the defendant, or &quot;definitely came from&quot; the defendant. Others will testify as to the circumstances surrounding the collection of the sample. It is then up to the finder of fact to evaluate all of the evidence plus understand the instructions regarding the criteria for finding the defendant &quot;guilty&quot;. Theoretically, Bayes Law could enter into an expert witness's (scientific) testimony, and likewise an opposing witness could contradict the putative relevance of BL in terms of reaching a scientific conclusion. BL could enter into the discussion at the level of the bottom line &quot;definitely/possibly does come from the defendent&quot;. The only practical way that I can see BL entering into the courtroom at least non-gratuitously would be if there is a dispute over the reliability of a certain test, thus should the testimony be allowed in the first place (it might be excluded as being unreliable). There is a genre of research (for example this) that addresses the problem of sketchy statistic inferences, pointing to a role for BL. I would say that the prospects are dim, not bright.
In general, you do not have civil recourse against the government for (lawful) legal process that you are the victim of. "Counterclaim" would only be applicable when A sues B, and B makes a counterclaim against A – the police don't sue you, they arrest you, and the prosecutor prosecutes you (or decides not to). If the police beat you up, you could sue them for violating your rights, under what is known as Section 1983. Given the scenario you describe, this comes closest to involving false arrest, meaning that there was no probable cause for arrest. Otherwise, the police have immunity for their actions. But if there is a legal arrest warrant, there is probable cause (existence of probable cause is the standard for issuing an arrest warrant), so no claim against the police will succeed. I am leaving out the anomalous concept of an unlawful arrest warrant, where a judge issued an arrest warrant but there is in fact no probable cause. Such a case would be covered by Section 1983, where either the judge or the swearing officer (or both) violated your rights.
The appellate court gets the trial transcript which includes all the testimony (and exhibits or descriptions/photos of them) and the trial court's rulings. Also, each side presents an appeal brief, which will generally include a statement of facts, pointing out ones it thinks favorable to its views. In civil cases a jury may be asked/instructed to give yes/no answers to a series of questions, but this is not normal in criminal cases. An appellate court can (and sometimes does) rule that there was not sufficient evidence to permit any reasonable jury to convict; to that extent it can rule on questions of fact. But, as the comment by ohwilleke mentions, an appellate court does not hear new evidence. It can overturn the conviction and send the case back for a new trial, and in such a new trial additional evidence may be introduce at the trial court level.
Will he break any laws by saying that (assuming the actual truth cannot be found out)? The statement made outside the courtroom is not itself perjury, since it is not made under oath. But that doesn't mean that there wouldn't be legal consequences. It would be powerful evidence in a perjury prosecution (surely enough for a conviction even standing alone long after the trial is over but within the statute of limitations for perjury in the jurisdiction from the date of the sworn statement, if any), and would be a waiver of 5th Amendment rights against self-incrimination, generally, in the perjury case. It might also be strong evidence (enough to convict standing alone) in a timely obstruction of justice prosecution. This statute of limitations could also run from the date of the sworn statement, or from the date of a false unsworn statement that caused a conviction to be reopened. If the statement made in court was favorable to the prosecution, it might bring these charges after the conviction in the underlying case is final. But, the out of court statement would probably be grounds for the party benefitting from the original statement to seek a mistrial or to have a judgment set aside if the verdict or judgment is consistent with the sworn statement. If the out of court statement was made before the trial was over, the witness could be recalled and the out of court statement could be used to impeach the in court statement. It might constitute a probation or parole violation. If the witness were testifying pursuant to a cooperation agreement, the out of court statement would probably breach the deal and deny the witness the benefit of the cooperation deal. The out of court statement might constitute contempt of court if made while the proceeding in which the statement was made was still pending. Depending on the nature of the statement, the out of court statement might constitute defamation for which some one whose reputation was tarnished might sue for money damages. (There is immunity from civil liability for in court statements.) It would violate the ethical rules of many professions. For example, an attorney would probably be disbarred for doing that. Arguably, in this situation, the statute of limitations could run from the later unsworn statement date rather than the date of the sworn statement. If the witness is a state or federal government employee, this could lead to impeachment proceedings, in the state legislature, or Congress, respectively. The aftermath of the Lewinsky Scandal (link below) involving Bill Clinton touches on many of these possibilities: Further investigation led to charges of perjury and to the impeachment of President Clinton in 1998 by the U.S. House of Representatives. He was subsequently acquitted on all impeachment charges of perjury and obstruction of justice in a 21-day Senate trial. Clinton was held in civil contempt of court by Judge Susan Webber Wright for giving misleading testimony in the Paula Jones case regarding Lewinsky and was also fined $90,000 by Wright. His license to practice law was suspended in Arkansas for five years; shortly thereafter, he was disbarred from presenting cases in front of the United States Supreme Court. Easier and Harder Cases The easier cases are those where it is undeniably clear from other evidence that the witness lied under oath, and the out of court statement merely puts the cherry on top of an already solid perjury case. The hard cases aren't the cases where "the actual truth cannot be found out". Instead, the hard cases are the cases where there is strong evidence that the statement made in court, under oath was true. For example, suppose Ted Cruz is asked in court: "Were you the Zodiac killer?" (A crime ridiculously attributed to him despite the fact that it is something that happened when he was a small child who live many hundreds of miles away.) And he says, "No" in court, but then leaves the courtroom and says in a press conference on the court house steps: "I am the Zodiac killer, I lied about that under oath in court today." Similarly, suppose that a DNA test on a certain blue dress shows a perfect match to President Bill Clinton and Bill Clinton says under oath in court, that the substance tested came from him on a certain day, in a certain place, when a certain person was wearing it, in a certain way (also confirmed by a witness and surveillance video). Then, he leaves the courtroom and says in a press conference on the court house steps: "Someone else was the source of that genetic material. I never met that person, and I was in Kenya on the day alleged and I've never set foot in the White House. I lied about all of this under oath in court today." In these cases, there is no plausible way to make an obstruction of justice or perjury charge stick, or to upset a verdict or judgment consistent with the truthful sworn statement. Contempt of court is still possible, as would professional ethics violations, but other consequences would be less obvious, because the act would come across more as absurd instead of something that genuinely confounds the truth. The legal consequences associated with the conduct in the original post are mostly aimed at sanctioning genuinely fraudulent conduct. Our legal system is more confused about how to respond to lies so blatant that they only amount to feeble and ineffectual gaslighting that no reasonable person familiar with the circumstances would believe (but that might incite crazy conspiracy theory thinking supporters). The harder case would lie in the uncanny valley between a bad joke and a pathetically weak attempt to mislead people, even though the law is clear about how to deal with clear sarcasm and convincing attempts to lie that can't be clearly proven or disproven with other evidence.
Generally, a local county judge’s decision is not binding on the judgement of another judge unless it is that of an appellate division. The law of the case principle could be referred to as an argument if it would have been decided by another judge in the same case (some courtships work on a rotary basis with different judges sitting over a single case). This would mean that the court would give greater deference to that decision; however, applying the principle is a matter of administrative preference to save resources of the court. Whether or not the other judge would reconsider the matter would be within their discretion absent binding authority to the contrary as a “law of the case” is not binding. In fact, even if it would have been the same judge with the exact same facts deciding the matter in a final judgement, there wouldn’t be much to do. One could argue that deciding differently is a violation of the Fourteenth Amendment which, if the judge fails to explain the different decision on the exact same facts may have a reasonable probability to get overturned provided the unconstitutionality finding was correct in the first place. If the matter was, in fact, unconstitutional, appeals may overturn a contrary judgement if the issue is brought up in the lower court and enters the court record. It may have some weight still to cite the decision of the other judge as the argument may be given more weight than if merely delivered as the argument of counsel.
