If a defendant is found guilty, they can usually appeal to a higher court. Is the plaintiff appealing an acquittal also allowed? Say Adam the accuser is taking Dave the Defendant to court. If Dave loses in his local district, I've heard that he can appeal the decision and be re-tried in a higher court (all the way to the Supreme Court, theoretically). But is the opposite also possible? I.e. if Dave is acquitted, is Adam allowed to re-try him in a higher court, hoping Dave will be found guilty this time?
In the US, the prohibition against double jeopardy provides a hard restriction against re-trial and appeal of an acquittal. The government cannot appeal an acquittal (U.S. v. Sanges, 144 U.S. 310, Ball v. U.S., 163 U.S. 662), and a verdict of acquittal without judgment is also a bar to re-prosecution. The exception is that if the defendant was never in jeopardy – the judge had been bribed – then there can be a new trial (Harry Aleman v. Judges of the Criminal Division, Circuit Court of Cook County, Illinois). However, Adam does not take Dave to court. Adam may make an accusation that motivates the prosecutor to file criminal charges. When Adam sues Dave (not a criminal matter), there is no acquittal or conviction, or guilt. There may be a finding of liability, or not. Either side can appeal to the top, as long as there is a legal basis for the appeal. If Adam is found not liable because the judge makes a legally erroneous ruling, if Dave objected properly to the ruling, Dave can appeal if successful, the court could then change its mind and find Adam liable.
Scotland has a third possible verdict, which covers much of the situation you are asking about: “not proven”. While still an acquittal, it is typically used by judges and juries in situations where they are not suitably convinced the defendant is necessarily innocent, but not convinced the evidence supports a conviction. As recently as 2015, attempts to remove the third verdict from the Scottish legal system were rejected, despite it being seen as an easy way out for courts.
Bob will be convicted if he is found guilty beyond reasonable doubt. Now it is a logical fact that he cannot be guilty of both crimes, but it is entirely possible that his first conviction was incorrect and he is guilty of murder. His defense would point out that the first conviction creates reasonable doubt about his guilt in the murder case. The prosecution would have to show how it doesn't, for example by finding a police officer who forged the evidence in the first case. And then the defence would point out that the fact that evidence against Bob was forged once means reasonable doubt for the evidence in the second case. Fact is, the prosecution must show guilt beyond reasonable doubt for the murder, and the fact that Bob was found guilty beyond reasonable doubt for a different crime, and that he cannot have committed both crimes, makes the prosecutions task a lot harder. Now what if the prosecution finds a second criminal who is an exact visual match for Bob? On the positive side, this would explain how there are two videos apparently showing Bob committing two crimes in different places. It would put the prosecution into the difficult position to have to prove which one is the murderer. And they can't say &quot;Bob is in jail already, so it must have been Bill&quot;, because now Bob's first conviction looks very unsafe.
Does the law or judge ever make exceptions for events such as this? From a legal standpoint, your friend is at high risk of being found in contempt and thus be sentenced to imprisonment. Your friend should have called 911 rather than violate the protection order under pretext of consoling her. Asking from the standpoint of whether judges ever do this or that is pointless. The answer would be &quot;yes, they make exceptions&quot; even in scenarios which are plain aberrant. However, a judge's departure of the law quite often is not a reliable standpoint for understanding the law, but the result of his/her ineptitude and unfitness for judicial office.
I have encountered this problem in Pennsylvania. The PA Code requires a District Attorney to approve all private criminal complaints. If the DA declines to prosecute, then an affiant can petition the Court of Common Pleas to review the decision. However the affiant bears the burden of convincing the court that the DA abused his descretion in declining to prosecute, which is a pretty high hurdle. In the United States the only other legal appeal I am aware of is through federal courts under broad federal laws like 18 USC 242 or 42 USC 1983.
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.
Alice files a lawsuit against Bob This is a civil suit, it will not lead to any court punishing Alice, or anyone else. If facts come out showing that Alice violated the law, the local prosecutor could, but need not, file a criminal case against Alice. If the prosecutor does not file such a case, Alice's worst possible outcome is to get no damages, with costs and fees awarded to Bob (or his estate). If Bob dies and Alice wishes to drop the case, there is no obvious reason not to permit it, unless Bob or his estate has counter-sued. Bob (or his estate) might ask for costs and legal fees, and perhaps sanctions for a frivolous suit. The court might well asses whether to grand such a costs order before or as it dismisses the case. ; The question seems to confuse the idea of a civil lawsuit and that of a criminal prosecution. In an Civil lawsuit, one person (or company) (the plaintiff) claims that another (or several others) (the defendant) have violated an agreement, or have in some other way caused legal injury. For example, if Alice claims that she had a contract with Bob and Bob violated the terms that would be a civil suit. Or if Alice claims that Bob infringed her copyright, or slandered her, or falsely advertised something or any of many other possible situations. The case would be Alice C vs Bob D. However, if Alice accuses Bob of having stolen from her, or punched her, or raped her, that woulds be a criminal accusation. The police would investigate, and if they found evidence to support the accusation, the local prosecutor could (but need not) file a case, which would be something like State of Franklin vs Bob D IN THE CRIMINAL COURT. Alice would be a witness, but not the plaintiff. If the investigation found that Alice committed a crime also, the prosecutor might file, State of Franklin vs Alice C Or the prosecutor might file both cases, or neither. The prosecutor has wide discretion whether or not to prosecute in any particular case, even when the evidence is clear. Neither Alice nor Bob could insist that either criminal case be dropped. Only the prosecutor, or the Judge, could do that. A criminal court is a different court from a civil court, and in many places a given judge hears only one or the other type of case. In many other places a judge may hear both kinds, but any one case is still either civil or criminal.
An appeal may be made by a plaintiff, prosecutor, defendant or other interested party, so the term 'defendant' is not very useful; the party opposed to the Appellant (and served with the appeal) is usually called the Respondent. A contested appeal just means that the Respondent wishes to be represented at the appeal, presumably to fight it; most appeals are contested, but not all. Unlike a first-order case which may go by default, an uncontested appeal will still have to have some sort of a hearing; you are, after all, saying that a court decision should be set aside, and the Respondent's views are not necessarily relevant. It is, though, fair to say that an uncontested appeal will have a greater chance of success.
