Can the victim of a crime throw a court case? Can the victim of the crime just turn down a lawyer and when asked to testify just plead the 5th so the defendant can not go to jail?
In principle, the victim can be granted immunity for his testimony. At that point, since his testimony cannot incriminate him, the 5th Amendment protections no longer apply. He can be ordered to testify and held in contempt of court if he refuses.
Sometimes rights conflict with each other, and the courts decide which right takes priority. The Sixth Amendment provides that a defendant is entitled to "compulsory process for obtaining witnesses in his favor". The Fifth Amendment says "No person... shall be compelled in any criminal case to be a witness against himself". And the First Amendment gives the right to free speech, which includes the right to not be compelled to speak. If you're on trial and try to get someone else to confess on the stand, his Fifth Amendment right against self-incrimination trumps your Sixth Amendment right to have him testify. But if he couldn't take the fifth (for example, if he had already been acquitted), your Sixth Amendment right would override his First Amendment right to free speech.
Yes, there are cases where refusing to respond to the question would be legal. The juror could plead the fifth – so long as he hasn't spilled the beans about what he is trying to protect – which provides for the protection from compelled self-incrimination (any incriminating statement that could be used against you in a criminal charge – civil liability doesn't count here). Anything that is said in voir dire is on the record and under oath. You are effectively witnessing against yourself. As stated on NOLO: Witnesses can assert the privilege against self-incrimination in civil proceedings as well as criminal ones, despite the seemingly limiting language of the Fifth Amendment. They can assert it in state or federal court, in a wide variety of proceedings (including trials, depositions, administrative law proceedings, and investigatory proceedings like grand jury hearings). . . . If, by answering, the witness could provide evidence that might aid the government in prosecuting him, then he has the right to refuse. There has to be evidence, though, that testimony would subject you to criminal charges. &quot;What is your hair color?&quot; obviously cannot subject you to criminal charges. &quot;Have you ever driven while intoxicated?&quot; Would only be incriminating while the Statute of Limitations has not passed. After that point, you have not 5th amendment protections for having driven under the influence because it will no longer subject you to criminal charges. Additionally, there are cases in which you could refuse to answer but the court could still compel you to answer. For instance, sometimes questions in voir dire get very personal. If jurors believe a question is too personal, they can try to refuse to answer on those grounds, let the judge know, and the judge would make the decision. If the judge decides they must answer, and they continued to refuse, the judge could hold them in contempt. On a slightly more practical note, if you are objecting to questions, it will impact whether the attorneys on either side will allow you to stay on as a juror. After an objection to a specific question, the attorney may just decide to nix you.
What is the process for having the plea withdrawn? Is it even possible at this point? Maybe, but YOU are not going to be able to do this on a pro se basis. It is clear from the way you word the questions you are still extremely emotionally invested in the whole scenario and want to make sure you get your pound of flesh at every turn. That is not going to work in this case. The first thing you need to accept is that for the purposes of the plea withdrawl the judge does not care to hear about how the lawyer tricked you. If you go in on your own pleading that your lawyer did you dirty, the judge is just going to deny your request in the best case. You will need a lawyer to prepare and argue the motion to withdraw your plea. Get a good lawyer they are worth their costs. Focus on the main goal of resolving your issue of the Criminal Trespass. How the police treated you or your Tenant took advantage of you does not excuse criminal behavior. So if the plea does get withdrawn focus on winning the criminal case. After the criminal issues are resolved then you can deal with the other issues.
The parties are generally entitled to present their case as they see fit, as long as they stay within the rules of evidence. If they want a straight yes or no, the court will often require the witness to provide one, which keeps lawyers happy, makes the answers clear for the jury, and limits the parties' grounds for appeal. If a yes or no answer is not as accurate as a more qualified answer, the other lawyer would typically have an opportunity to invite the witness to provide a fuller answer on redirect. If a yes or no answer is inappropriate because of assumption embedded in the question -- as in your &quot;beating his wife and kids&quot; example -- the question should quickly elicit an objection from the defense attorney, who would note that the question lacks foundation or assumes facts not in evidence. Assuming there isn't any evidence of domestic violence, the court should sustain the objection, in which case the witness would not need to answer at all.
So, as you say, these witnesses who try to help their buddy out may be committing perjury. Also, D himself, by lining this up, is probably on the hook for conspiracy to commit perjury and being complicit in perjury. Aside from that, I think your question is: would getting people to testify in a way that implies they did the crime lead to an acquittal for the murderer? The answer is: maybe. The jury will either vote to acquit or to convict. If the jury votes to acquit, then it's over. Double jeopardy protects D from being tried for murder again. But, if the jury votes to convict, the fact that D had his friends testifying in the way you suggest isn't going to get the conviction overturned on appeal because &quot;a reviewing court resolves neither credibility issues nor evidentiary conflicts.&quot; People v. Young, 34 Cal.4th 1149, 1181 (Cal. 2005). I haven't done a trial yet, but it strikes me that that might not be the greatest trial strategy. I think generally defense lawyers would prefer to make their client look the furthest thing from gang affiliated as possible. Don't lie to a court or ask anyone to lie to a court for you.
Civil litigation involves general causes of action that are available to anyone, including both private parties and the government. Civil courts are designed primarily to provide restitution to the injured party. Criminal courts exist for governments to exercise their police powers: specific, limited authority held only by the government. The principal purposes of criminal law are...well, they're debated, but broadly speaking, it's to punish and/or rehabilitate the criminal and deter future criminals. Because criminal conviction can result in jail time and even the death penalty, there are more stringent procedural protections accorded to criminal defendants than there are to civil defendants. So when the government's goal is to recover damages, it's easier for them to use the less burdensoome civil procedures, just the same as anyone else would. Let me give you an example. Someone steals your identity and runs up $100,000 on your credit card. You call the police, and they find someone they think is the guy. To convict him, the police must convince an entire jury panel that he did it, beyond a reasonable doubt--a high standard. He pleads the fifth, and without his testimony, the police may not succeed. If they do, he will be sent to jail, and he may also be ordered to give part or all of your money back. If the case is weak, however, the police may not want to spend their limited time on it--and that's their call, not yours. (This also applies to government agencies; only law enforcement can bring a criminal case, not any government agency.) However, you can also file a civil lawsuit. In that lawsuit, depending on the jurisdiction, you may only need to convince some of the jury--civil verdicts don't always have to be unanimous. You may even just face a judge, with no jury. And the legal standard is a "preponderance of the evidence," which in layman's terms just means "more likely than not"--a much easier thing to prove. Because the Fifth Amendment doesn't apply to civil litigation, you may even be able to argue before the jury that the defendant's refusal to testify suggests he's guilty. In summary: civil lawsuits use different rules and procedures, which may make it easier to recover money (or get other civil relief, such as an injunction) in cases where that's the goal. These courts are open to anyone, including the government. But if the government wants to use its special police powers to put someone in jail or get other criminal relief, they have to use the stricter criminal rules and procedures.
Yes, why not? It happens all the time. Usually the witness will just say, "I am not sure" or "I don't remember, exactly". Also, if Bob is the only witness, how would anyone prove that he was committing "perjury"? In the case of an uncooperative or dissimulating witness, Judges sometimes can hold them in contempt of court, but it is pretty rare. In general, the court has to find "beyond a reasonable doubt" that the witness is refusing to testify honestly. (See "Federal Grand Jury Practice and Procedure" by Paul Diamond) It depends very much on the situation. Note that just trying to act "drunk" would not be a good idea, because that is contempt of court.
