Are there penalties for withholding self-exculpatory evidence during a trial? Suppose a person is put on trial for a crime, but he has video evidence showing his innocence. Out of malice or spite of a personal nature towards his accuser, he allows the trial to proceed, and then at the last possible moment "discovers" and presents the evidence, leading to his acquittal and the accuser's extreme shock, dismay, and embarrassment. Are there any sanctions that could be applied to the defendant if the court were convinced he had withheld that evidence in order to prolong the trial?
This is a good question, although it discusses crimes. This answer generalizes the question by giving a response for civil violations. In the united-states, where federal civil-procedure is followed and provided the tape isn't solely for impeachment purposes (i.e. it also documents other elements), there are certain disclosures required at the beginning of discovery governed by Rule 26(a)(1)(A)(ii). If a party withholds one of these disclosures, under Rule 37(c)(1), the court is able to take a number of actions, including throwing the evidence out. This could, of course, result in the withholder's conviction. Yet, if the court does not go to that extreme, it may impose the sanctions in Rule 37(b). So the withholder's attorney might try to make a case that the evidence is, indeed, solely for impeachment purposes.
The burden of proof is always on the plaintiff (except for counterclaims brought by the defendant against the plaintiff). In your example, the businessman has to prove that he did not rape her.
How exactly would the court determine this to be the cause of divorce? 99.99% of the time, this would be purely a &quot;he said she said&quot; situation, for how can someone prove refusal to engage? You can prove the opposite if there are children born to both parents, but how can one prove a negative? Or is the statement by the divorce initiator considered sufficient for the judge? Testimony under oath is evidence. Judges resolve &quot;he said she said&quot; situations every day on a routine basis with witness testimony alone by judging the credibility of each witness before them. See also an answer by @Jen about the subject of how things are proved in court in general. In the appropriate case, testimony under oath with no other corroborating evidence can even support a murder conviction as proof beyond a reasonable doubt. It can certainly suffice to prove marital fault in a civil lawsuit for a divorce. If the judge finds that witness testimony under oath between more than one witness is irreconcilably different, and each witness is equally credible, and that it is impossible to tell which person is telling the truth, then the person seeking relief from the court has failed to meet their burden of proof to obtain relief from the court. But, this is rare. Usually, when witnesses are both testifying under oath and disagree about what happened, the judge will find that one witness is more credible than the other. And, in truth, while people certainly do lie in open court under oath, and probably are more likely to lie in that situation than when speaking to someone not under oath outside of a courtroom, most of the time, people don't lie and the testimony of all of the witnesses are consistent with each other subject to limitations based upon what they could perceive from their perspective and the limitations of imperfect memories. This could come down to demeanor in court, hesitation in answering, &quot;tells&quot;, inconsistencies in their testimony, corroboration from other evidence and other witnesses (e.g. what someone said to a friend or wrote in a diary at the time), evidence that a witness has been convicted of a crime of deceit in the past, use of language that suggests coaching about their testimony, or common sense judgments about whose story seems more plausible under the circumstances of the parties in front of the judge.
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.
I will assume that your question pertains to the United States. In other jurisdictions, different rules could apply. Context matters. The usual penalty for spoliation of evidence (the technical term for what you describe) in a civil case is a judicial determination or jury instruction that the evidence destroyed would have established the relevant part of the other side's case had it not been destroyed. In all of these cases, your failure to take affirmative action to preserve the evidence once you knew that there was a bona fide likelihood that you would be sued could be held against you by making an adverse determination that the evidence would have been unfavorable to you and possibly also money sanctions. You could not be held in contempt of court for this if these events happened before a case was commenced. In a criminal case, where you are a defendant, you have an absolute right to not incriminate yourself and do not have to take affirmative action to preserve evidence, although this right is limited to criminal cases and your failure to preserve evidence can still be held against you in a civil case. Certainly, in situation 4 you are a potential criminal defendant, so the 5th Amendment protection would apply. In situations 1 and 2, where the precautions were not put in place to facilitate a crime, the 5th Amendment would protect you if you were a potential criminal defendant, but suppose that you are a bystander like a third party ISP representative. If you were a third party, at a minimum you would have to be put on notice of the police need for the evidence, would probably have had to have had the police ask you for the evidence, and of course, would have to be aware that the destruction was imminent and have the power to prevent that destruction. If all those conditions were present, you might be guilty of obstruction of justice (there are precedents for inaction knowing of the consequences in the fact of a police question amounting to obstruction of justice). In situation 3, this kind of action pretty much amounts to being an accessory to some crime before the fact (unless someone was successfully deceived by a very elaborate story) and would likely make anyone involved part of a conspiracy to commit the crime that the destruction of the papers would facilitate. While the papers themselves might have been evidence of a crime or civil wrong, the destruction of the papers might itself be considered part of the crime, regardless of what could be established regarding the actual content of the papers.
Not necessarily. Let's say the victim delivered photos of a harm that were alleged to be done by the defendant. That's a crime in itself. But based on this item the DA orders investigation and finds evidence of a real crime. Discovering that the photo was faked can lead to dismissal (with prejudice), but even without the fake photo, there might be a strong case against defendant. Also, the photo could not even be used as evidence in the actual trial stage. A good defense attorney might manage to convince the judge, that the doctored photo should have been discovered such early in the investigation, but I doubt, that one could manage to make everything else in a proper investigation fruit of the poisoned tree unless police screwed up.
There is a big difference between knowing something and proving it. A lawyer who knows a client is guilty can take steps to prevent the state from proving guilt. (E.g., motion to exclude evidence, cross examining witnesses.) The belief that a client has committed a crime does not necessarily mean one knows what specific crime was committed. Is a killing Murder 1, Murder 2, or manslaughter? There are defenses even when an act may be a crime. E.g., self defense, insanity, justifiable. Lawyers are not permitted to assist in perjury. E.g., allow the client to testify to something he knows is false.
what is the sequence of proceedings? See Rule 25.9: the prosecution summarizes the case the defendant has an opportunity to concisely identify what the defendant intends to put into issue the prosecution introduces all of its evidence (including all of its witnesses) (and the defence has the opportunity to cross-examine each) the defendant has an opportunity to ask for a directed verdict of acquittal the defendant has an opportunity to summarize the defence case the defendant has an opportunity to introduce evidence, including witnesses (and the Crown has the opportunity to cross-examine each) either side may introduce additional evidence if needed in rebuttal prosecution's closing submissions defendant's closing submissions
