Can a plaintiff call the defendant as a witness in a civil trial? Alice is suing Bob, representing herself. She has decided that her best strategy is to catch Bob in a lie to undermine his credibility. Can Alice call Bob as a witness? What questions can she ask?
Only in a civil case Yes, in a civil case, Alice generally can call Bob as a witness to take the stand. In many cases, this is done very early, locking in their testimony, before expert witnesses or other evidence by the plaintiff are presented to try and undermine the testimony. Alice may ask only questions that have relevance to the case. Let's take for example a dispute about a contract: Alice may ask Bob if he engaged in negotiations to form the contract, about the matter of the contract, if he signed the contract, or how he (or his employees) fulfilled (or not) the contract. Pretty much everything that pertains to the contract or the execution thereof. This does not extend to the settlement of the case or attempts thereof. Alice may not ask if Bob has an affair with Clarice unless that somehow is material to the contract at hand. Alice may not re-ask questions where an objection was sustained in the same way. However, Bob might not need to answer all questions (there are things that are banned from being asked), especially as Bob's attorney will object to questions. A few examples of competent questioning can be seen towards the end of My Cousin Vinnie, though this is a criminal trial. Never in a criminal trial In a criminal trial, not only can the prosecution not call Bob to the stand, he has to elect to go to the stand to even be questioned by the prosecution. That is because he can &quot;plead the 5th&quot;. There is a tiny exception for civil cases, where they can do so there too.
In the United States, the question that determines whether it's perjury is whether or not you believe what you said was true. Whoever— (1) having taken an oath..., willfully and contrary to such oath states or subscribes any material matter which he does not believe to be true; or (2) ... willfully subscribes as true any material matter which he does not believe to be true; is guilty of perjury. So if an attorney asks if you saw the defendant, and you believe you saw the defendant, &quot;yes&quot; is generally going to be the correct answer. You're free to qualify your answers or answer questions that weren't put to you, but you aren't obligated to do so. Generally speaking, our adversarial system puts the burden on the defense to ask if you're sure, how the lighting was, whether you were wearing your glasses, whether you were drunk, etc.
Your belief in the truth of a statement is of only limited value in a defamation suit. Saying that a person is incompetent in that person's profession can certainly be defamation, and may even be defamation per se, depending on the jurisdiction. If the person sues and the speaker asserts truth as a defense, the speaker may have to prove that the statement is true. Why would one need to say anything at all in such a situation? Whether such a statement was a factual statement or a statement of opinion would depend very much on the detailed circumstances. But it is at least possible that a suit might be filed and won on this fact pattern. See this answer for more on defamation under US law.
I've never heard of a rule specifically addressing this in the united-states, but I expect most courts would disallow it. I suspect a court would believe that the note-taking would be a distraction to the witness, whose focus should be on listening to the questions and providing truthful answers. The note-taking may be perceived as a distraction from the testimony for others in the courtroom, as well. If I were examining the witness, I would probably be entitled to see what the notes say, dragging out the witness's examination. Then the witness would want to take notes about my questions about her notes, and I'd want to see those notes, and you can see how it can get out of control.
Generally they don't. If the conversation was made while there was a third person present, the person can be a witness at trial. Unless the witness is impeached, the witness's statement may be sufficient for you to meet your burden of proof to show the statement was made, because the burden is just a preponderance of evidence in most civil cases. Note that, the existence of a statement is not sufficient to prove breach of privacy. The context surrounding the statement is important. If you intend to record communications from the landlord in the future, please check with your jurisdiction's laws regarding recording of communications. Many jurisdictions (such as California) only permit a private communication to be recorded when all parties give consent. Not only an illegally recorded conversation is inadmissible as evidence (with the exception to rebut a witness), it is also a crime to do so. Some other jurisdictions in USA allows one party to record the conversation without obtaining consent from the other party.
She would want a litigation attorney that specializes in this kind of case. For instance if the underlying issue is an OSHA violation, there may be questions that imply a degree of culpability by the witness, and an attorney who knows that area of law (as opposed to copyright or drug-trafficking) would be in the best position to protect the interests of the witness.
Often, you aren't screened only for one trial, but for several trials. If you declare yourself biased for one trial, you might be asked to be considered for a second, or third, etc. If you continue to give answers that make yourself ineligible such that the judge does not believe you are telling the truth or acting in good faith, you can be held in contempt of court.
what reasoning would the court use to evaluate the competing claims? Absent a verifiable contract, the dispute would require assessment of the extrinsic evidence and/or of other aspects reflecting the parties' credibility. Those types of factors would help for discerning whose position is meritorious. You are right in that Bella's co-signing of the loan is likely to render her hypothetical allegation of gift not credible. Bella's history of defaulting on her debts as well as her failure to keep up with insurance &amp; tags are examples of prior act evidence. As such, these might be inadmissible for proving that she entered the contract with Abe. However, they are admissible both for proving Bella's pattern of missing her commitments and possibly for detecting inconsistencies in Bella's allegations (thereby weakening Bella's credibility). Unless Bella is able to point greater inconsistencies or weaknesses in Abe's credibility, a competent and honest court (where available) would rule in favor of Abe.
