Why can NTSB reports not be admitted as evidence? According to 49 U.S. code § 1154, part (b), No part of a report of the Board, related to an accident or an investigation of an accident, may be admitted into evidence or used in a civil action for damages resulting from a matter mentioned in the report. That is to say, an NTSB report may not be used as evidence in a civil action for damages, resulting from an aviation incident. This is re-iterated at the end of most final NTSB reports. My question is what is the motivation and reasoning behind this legislation? While some of the elements of the report may be of a subjective nature, there is a specific section detailing factual information. Could the motivation be to force admittance of the original evidence, rather than the NTSB report which would potentially secondary source? A more interesting aside is also, can it be admitted into evidence if the civil action is not for damages from the incident in question? What if a report has tangential relevance in a potentially non-civil, say, criminal action?
"The purpose of the statute making the NTSB's reports of accidents inadmissible in actions arising out of such accidents is to exclude reports that express agency views as to the probable cause of the accident because that is a finding in the province of the jury or fact finder." Britton v. Dall. Airmotive, Inc., No. 1:07-cv-00547-EJL, 2011 U.S. Dist. LEXIS 163211, at *5-6 (D. Idaho May 20, 2011) (citations omitted). "The legislative history of this statute demonstrates that the purpose of this exclusionary rule is to prevent a usurpation of the jury's role as fact finder." McLeod v. ERA Aviation, No. 93-294, 1996 U.S. Dist. LEXIS 3204, at *3 (E.D. La. Mar. 12, 1996) (citations omitted). "This limitation on the admissibility of the NTSB report, however, applies to the official conclusions of the NTSB, not to the factual accident reports of the investigators." Britton, 2011 U.S. Dist. LEXIS 163211, at *6 (citation omitted); accord 49 C.F.R. § 835.2. By its terms, the statute applies only to civil actions, but the report would be subject to the ordinary hearsay rules if offered in a criminal case. See Fed. R. Evid. 801; United States v. PG&amp;E, 178 F. Supp. 3d 927, 946 (N.D. Cal. 2016).
Lawyers may break confidentiality with client permission. You can also break your own confidentiality and talk to the prosecutor yourself. The prosecutor's response is up to the prosecutor; however, they tend to not be super excited about giving immunity to a witness for the defense if they might want to prosecute the witness later (and courts often are fine with that), so the more they suspect about your true role the less likely they are to grant it. No. If the feds later find truly independent evidence (they have the burden of showing it's truly independent), they can prosecute. Some states give transactional immunity to witnesses (you can't be prosecuted for crimes you testified about for any reason), but the Fifth Amendment doesn't require it and at least the feds aren't bound by state transactional immunity. It's hard to prosecute, but is possible if prosecutors play their cards right. Yes, it does allow civil liability. There is no right against self-incrimination in civil matters, only criminal liability. If the forced testimony leads to a lawsuit that bankrupts you, too bad.
The standard in civil trials is "on the balance of probabilities" or "more likely than not." This is often expressed as "more than 50% likely", but this question is meant to provide an edge case to this standard of proof. Despite one person being provably innocent, could all 3 people be found civilly liable for 1/3 of the damages, since each individual has a 67% chance of having committed the crime? General Rule: No Generally speaking, the answer is "no". A plaintiff must prove liability by a preponderance of the evidence as to each individual defendant. This flows from the basic structure of tort lawsuits (a civil claim alleging damages suffered from criminal acts is a form of tort lawsuit). The Narrow Market Share Liability Exception There is pretty much only one circumstance where something similar to your example. But, it isn't strictly analogous because it only applies when all of the defendants can be proven to have harmed some of the plaintiffs and the only question outstanding is who harmed whom. Defendants may be innocent of harming some of the plaintiffs, but can't be innocent of harming any of them, to face liability in this scenario. This occurs which is when a class action lawsuit is brought against all (or almost all) of the multiple separate defendants who manufactured the products of the same type, all of which were defective. A manufacturer of a defective product is strictly liable for all harm caused by the defective product, but usually a plaintiff must show precisely which defendant's product caused that particular person's injury. But, in the class action context, where (almost) all of the people who made the defective products are sued by (almost) all of the people who were injured by defective products of that type, courts have allowed the class to recover an amount calculated to represent the aggregate economic value of the damages suffered by all members of the class combined. Then, the aggregate damages award is allocated among the defendants in proportion to their market share of the defective product. Then, the amounts paid to the class by the various defendants are then allocated to members of the class based upon the estimated damages suffered by each subgroup of class members (or in separate case by case damages hearings). This is an exception to the usual requirement to prove causation against each individual defendant in the case of each individual plaintiff, because the risk of injustice by the process overall to any given defendant is small, and requiring proof of causation in this situation creates a burden on plaintiffs that lacks the justification that it would have if the injured parties had sued on a piecemeal basis. But, this only works when the defect in the product was shared by everyone who made that kind of product, and was not simply a "quality control" issue in the manufacturing process. For example, this kind of market share causation could be appropriate against all makers of tobacco products or asbestos or lead based paint. But, it would not be appropriate in a product liability case where some cars with built with substandard parts while others were built with parts that met the specifications for the cars and those that were did not cause any harm.
No Federal law and most states have an notice of alibi rule that requires a defendant to identify witnesses who will testify as to their alibi and where the defendant claims to have been. The validity of these rules was upheld by the Supreme Court in Williams v Florida: The Fifth Amendment would not be violated if, after the alibi witness had given evidence, the court granted a continuance to allow the prosecution to seek rebuttal evidence (this point was conceded by Williams's lawyers). Consequently, all the notice-of-alibi law did was allow the prosecution to do so before the trial, instead of having to interrupt the trial. It did not provide the prosecution with more information to use against a defendant than they would eventually get in any event.
Can a Lease with Missing Pages be used as Evidence in Court? Yes. Being relevant to the claim(s) and signed by the parties gives the filed pages evidentiary weight. If the filed evidence is disputed, its filing shifts to the adversary the burden of proving that the missing portions of the contract outweigh the materiality of that evidence or that the filed pages are unreliable (i.e., fake). Likewise, during discovery, the party who only preserved some of the pages could (1) request the adversary to provide a copy of the signed contract, and/or (2) submit a request for admissions in which the adversary is asked to admit or disprove terms of the lease that are at issue.
As a comment by @DavidSchwartz notes, this is not wrong. Questions of law but not fact are allowed. It is worth noting that the line drawn is arbitrary. In Colorado, where I practice, jurors issue written questions (pre-reviewed by the judge and counsel for all parties before being presented) to witnesses at the close of the testimony of each witness called by a party to testify. This is very helpful to counsel, as it provides indirect evidence of whether the jury understands what they are being told, and often juries will directly ask questions that for tactical reasons, both parties have refrained from asking that go to the heart of the matter. It also frequently clarifies misunderstandings that trained legal professionals assumed were not made about terminology. This is more problematic in criminal trials, where jury questions could provide evidence pushing a case over the threshold of proof needed to prove beyond a reasonable doubt that the prosecution failed to provide, than in civil cases with a preponderance of the evidence standard. Also, as a matter of reality, when jurors ask questions, counsel often loathe to object even when they have valid grounds to do so, for fear of offending the decision-maker, unless it is really critical to keep certain information away from the jury.
That's the entire point of a summary proceeding. You're allegedly found committing an offence, that isn't worth the court's time to hear but nevertheless requires some penalty. The only way to "unambiguously deny liability" is by requesting a hearing and denying liability in the notice of this. The court doesn't care what you say to everybody else, it cares what you say on its record. The reasoning is, if you're so sure you're not guilty of an offence, why haven't you sought to argue this in court? And if you weren't committing the offence, why did the informant serve the infringement notice in the first place? The act is not silent at all on this. If you don't request the hearing and serve such notice by the date required, you are liable to enforcement action - whether you deny liability out of court is irrelevant.
If the question asks, "did you do X" where X is or includes a crime that you could be criminally prosecuted for, you can invoke the 5th amendment in refusing to answer that. I have seen that done and seen that objection to the question sustained in court. However, if admitting to X would provide only civil liability, then the 5th would not apply. At trial, you may also have to take care not to give direct testimony on things that are so closely related that you "open the door" to being required to answer that question. For example, you can't say "I don't owe because I did X" and then expect to not have to answer "So just to be clear, did you do X?" Also, depending on context, invoking the 5th might cause a jury to view your testimony more skeptically (cpast points out that "For civil cases, adverse inferences based on pleading the fifth are totally okay"), and if that's going to come up you should ask your attorney about whether or not it'd be a good idea strategically.
