Can a judge&#39;s decision to admit or not to admit &quot;character evidence&quot; under Wis. Stat. &#167; 904.04 be challenged (on appeal)? In the heated exchange between the judge and prosecutor (see 2nd video here) in the Rittenhouse trial, the judge says that he admitted &quot;90404&quot; evidence in other trials that the defendant was intending to shoot people on other occasions, but that he's not allowing it in this trial. It seems to me that this kind of decision by a judge can basically make or break a case based on intent, outside of the extremely clear cut ones when the defendant says something like &quot;I'm going to kill Mr. XYZ [specifically] because I hate him [in particular]&quot;. &quot;90404&quot; seems to refer to Wis. Stat. § 904.04, which seems to be about &quot;character evidence&quot;. So, I'm curious if this kind of judge's decision to allow or not to allow such evidence can be appealed anywhere, or if his ruling is final under Wisconsin law.
Acquittals in criminal jury trials cannot be appealed (at least in a way that affects the outcome, Colorado and a few other states allow criminal appeals by the prosecution solely for the purposes of clarifying the law prospectively). Interlocutory appeals (i.e. appeals before the case is over) by the prosecution are allowed for pre-trial rulings (e.g. suppression of evidence rulings in a pre-trial hearing), in criminal cases, but not for evidentiary rulings made in the midst of a jury trial (which is when jeopardy attaches for the purposes of the double jeopardy rule, which is what prevents acquittals from being retried). An error in a ruling on an admission or rejection of evidence at trial may be appealed by a convicted defendant if the alleged misapplication of the evidence rule was an abuse of discretion by the judge, and was not &quot;harmless error&quot; (i.e. if as part of all errors made in the case there is a reasonable probability that it changed the outcome that the jury reached).
The only thing which has a name and sounds somewhat like what you're talking about is &quot;jury nullification&quot;. This generally refers to the situation where a jury deliberately sets aside the judges instructions about the law and supplies their own interpretation. For example, Peter Zenger was technically guilty of seditious libel because as a matter of law the material was sedition libel and the only legal question was whether he had published it. The jury found him not guilty, on the grounds that the statements were true, but truth was not an element of the crime. It is the general pattern in the US that the judge is the only person empowered to say to the jury what the law is. By selecting specific instructions (phrased as &quot;If you conclude X, you must find the defendant guilt&quot;, that is, stating the &quot;finding-to-verdict&quot; equation), the jury is given a formula for figuring out what the law says. Trial judges are not the ones who decide what the &quot;framers&quot; of the law intended, that comes from higher appeals courts who may study the legislative history. It can happen that a law uses an unclear phrase like &quot;irreconcilable differences&quot; and the jury doesn't know exactly what that means: then the judge may tell them to decide on their own, or give them a dictionary (however, there probably is an instruction for divorce law, and it's unlikely that a jury would be involved in a simple marital dissolution). It is entirely possible that jurors will end up misinterpreting what the law says in some instance, but I doubt that it happens very often. It is more likely that jurors will deviate somewhat, compared to judges in a bench trial, in matters of judgment such as whether an action is &quot;reasonable&quot;.
A judge has the authority to determine what law applies to a case and to instruct the jury accordingly, and also has the authority to determine which evidence is admissible. Presentation of a defense, in practice, involves presentation of evidence supporting a legal theory. In order to be admissible in evidence in an evidentiary hearing or trial, the evidence must be relevant to a legal theory that is in some way connected to the evidence. If no reasonable juror could make a ruling establishing that a legally recognized defense was established based upon the proposed evidence (especially if the proposed evidence is prejudicial to the prosecution case on the basis of reasoning that is not a legally valid defense) it can be excluded. For example, evidence in support of the theory that the defendant murdered the victim because the murder victim raped the defendant's sister six years ago, might very well sway a jury to acquit the defendant. So a defense attorney might want to make this argument. But, this is not a legally recognized justification for murder, so evidence in support of this defense would be excluded as irrelevant by the judge. In federal court, and in states with rules of evidence based upon the federal rules of evidence, the primary legal authority behind this is Rule of Evidence 402: Rule 402. General Admissibility of Relevant Evidence Relevant evidence is admissible unless any of the following provides otherwise: the United States Constitution; a federal statute; these rules; or other rules prescribed by the Supreme Court. Irrelevant evidence is not admissible. Some states also have procedural notice requirements for certain kinds of affirmative defenses. For example, if someone is arguing an alibi, a notice of an intent to present this defense must be provided by the defense a certain number of days before trial, so that the prosecution can develop the very different in kind type of evidence needed to rebut that defense, rather than having someone acquitted due to surprise when rebuttal evidence exists but the prosecution doesn't know in advance to locate the necessary witnesses and evidence to rebut this kind of defense.
What are the factors in weighting whether to disclose substantive evidence vs. using it for impeachment at trial? In an adversarial system (such as that in the jurisdictions in the U.S.) the surprise factor is disallowed on trial. I am not knowledgeable on the procedural exceptions, but generally speaking the documentary evidence (including deposition transcripts) has to be filed during the discovery stage of proceedings. A discovery deadline is set up during case scheduling, and extensions of that deadline have to be requested via motion. There is the slightly related concept of sequestration of witnesses whereby inconsistencies may serve to impeach a witness's testimony, but that is different than withholding from the jury any pre-existing evidence that a plaintiff would like to be considered on trial (whether for impeachment or otherwise). Also, it is in the injured party's best interest that the jury get to see the evidence rather than have it merely rely on a witness's reaction of surprise. The wrongdoer's lawyer will try to confuse the jury and thus outweigh the jury's perception of a "surprised witness", but that attempt is likelier to fail if the jury has the evidence with which to compare the witness's testimony at trial.
Your ability to assert your Fifth Amendment right against self-incrimination is not limited to cases where you are on trial or have been accused of a crime. Your ability to assert that right is also not an absolute bar against being ordered to testify: if you are given immunity, you can be forced to testify. Alice cannot hold Bob in contempt – only the judge can. Bob can explain to the judge why a simple truthful "yes" or "no" answer is not possible, if he knows how to do that (does he understand the notion of a false presupposition, or unclarity?). He could for example assert truthfully that he does not understand the question (pointing to the distinction between "Charlie's body falling on the vase, causing it to fall and break", and "Charlie acting with apparent intent to break the vase", since it's not patently obvious that the former scenario constitutes "breaking the vase"). However (changing the scenario a bit), he has to understand that if the question is "Did Charlie shoot Delilah?" and the fact is that Ethan forced Charlie to shoot Delilah, saying "No" based on a theory of blame is not reasonably interpreted as truthful testimony. Taking the 5th, without setting forth your basis (not understanding the question) runs the risk that the prosecution will grant immunity from prosecution, and therefore you don't get to avoid answering the question. Immunity covers various things except that it does not cover prosecution for perjurious testimony. See US v. Apfelbaum, 445 U.S. 115: the Fifth Amendment does not prevent the use of respondent's immunized testimony at his trial for false swearing because, at the time he was granted immunity, the privilege would not have protected him against false testimony that he later might decide to give. Immunity is conferred under the control of some applicable statutory law, such as 18 USC 6002 which says that no testimony or other information compelled under the order (or any information directly or indirectly derived from such testimony or other information) may be used against the witness in any criminal case, except a prosecution for perjury, giving a false statement, or otherwise failing to comply with the order.
The defense has an opportunity to question the witness the prosecution had called to provide foundation for the evidence, and in this case the defense's perspective is that the prosecution was trying to introduce evidence that they had improperly digitally manipulated. Part of their questioning was trying to figure out how the witness had manipulated the image prior to offering it as evidence. It's the prosecution's burden to prove that the evidence they are offering is accurate, the defense's purpose in asking the witness questions he could not answer is to try to prove to the judge that the prosecution has not laid proper foundation for the evidence because it has been manipulated from its original form in a way the prosecution cannot explain or justify as remaining fair and accurate to the events captured by the original footage. This case in particular had a lot of video evidence, and most of these issues were handled in motions in limine before the trial started. However, the drone evidence in question was dropped at the prosecutor's office after the trial started, so the prosecution did not really have time to hire and voir dire an expert witness on Amped 5 (keeping in mind that the defense similarly had little time to review and account for the new evidence in the middle of trial). Since the defense in this case were cross-examining the witness, they have some leeway to present an argument with their questioning like they chose to do with the red/blue pixel drawings. As I recall the judge allowed the evidence as-is, so it does not appear that the defense's arguments were persuasive to the judge.
There are no such laws that are specific to rape, but there are general laws about false statements. In every state there is some law against making a false statement to a government official, e.g. Washington RCW 9A.76.175 which says that one who "knowingly makes a false or misleading material statement to a public servant is guilty of a gross misdemeanor". To shift context slightly, if you report to the police that Smith stole your lawn mower when in fact you gave it to him, that is a false statement. However, there would have to be clear proof that you lied in your report, and not that there was a misunderstanding. If Smith stole the mower but the evidence did not support a theft conviction, that does not mean that you can be prosecuted for making a false statement (whereas, if someone has a video of you telling Smith "Here's a mower, which I give to you because I like you", then you could almost be prosecuted for making a false statement, were it not for the fact that the video is illegal in Washington). Perjury is the other related crime: RCW 9A.72.020 "a materially false statement which he or she knows to be false under an oath required or authorized by law". [Addendum] About the video of the mower being given away... Washington is an all-party consent state, meaning that you can't just record people, you have to have their permission (everybody's permission). RCW 9.73.050 says that information obtained by illegal recording shall be inadmissible in any civil or criminal case in all courts of general or limited jurisdiction in this state, except with the permission of the person whose rights have been violated in an action brought for damages under the provisions of RCW 9.73.030 through 9.73.080 which is to say, "unless the person(s) who did not give permission to be recorded now give permission for the evidence to be admitted". Since "you" would be the one making a false statement, "you" would have an interest in suppressing the video, thus "you" could withhold permission for the video to be introduced.
This is a question of civil procedure more so than law. The customs and practices of civil procedure are established by legal precedent, not laws made by legislatures. In general, a witness can answer a question however they want as long as it is responsive to the question. Litigators will attempt to bully a witness into certain types of answers, but this is not "illegal" nor is it "illegal" for witnesses to craft their answers as they like. As for yes-no bullying there are two general cases: (1) The question is factual. If the questioner asks a purely factual question, like "Did you go to the factory on that Tuesday?" then a yes-no answer can be compelled. If the witness tries to explain why he went to the factory, or something, then he can be cut off, because he is being unresponsive. (2) The question is hypothetical. If the question is hypothetical or suppositional, then the witness can reject the question. For example, if the question, "You told your boss that you hated your wife, isn't that right?" In this case the witness can answer, "I reject the question, the prosecutor is putting words in my mouth." or can say "I resent the implication." or "That does not accurately reflect what happened." or whatever. Any time a question "paints a picture" or establishes something hypothetical and simply asks the witness to agree with the fantasy scenario, the witness can refuse to answer, or can answer with a counter scenario which they consider to be more accurate. I would add that in case (2) where a questioner tries to paint a false scenario, it is a risky move, because it opens the door for the witness to say whatever they want. For example, imagine this exchange in the courtroom: Prosecutor: "You told your boss that you hate your wife, isn't that right?" Witness: "What actually happened is..." Prosecutor: "That is a yes or no question, answer yes or no." Witness (to judge): "Your honor, the question mischaracterizes the conversation I had with my boss, I want to explain what actually was said." Judge: "The witness may proceed with his answer." Prosecutor: "I withdraw the question." Defender: "The prosecution has opened the door, let the witness answer." Judge: "The witness will answer the question." So, now the witness has permission to answer however he likes, and the prosecutor has blundered by making a vague question that created the situation where that was possible. The main thing a witness has to do is not try to say irrelevant things or try to add information beyond what was asked for, in that case the questioner can cut them off.
