How can I tell if a court case exists? As someone without access to pricy legal search engines, how can I tell if a given case exists? For context, a lawyer was recently found to have cited a number of cases hallucinated by ChatGPT. The transcript of his ChatGPT session is now online. ChatGPT cited 39 cases in response to queries by the lawyer; I'd like to see how many of them are real. Some, such as Bell Atlantic v. Twombly are easy &quot;yes&quot;s: they've got Wikipedia articles. Six of them, such as Varghese v. China Southern Airlines, are easy &quot;no&quot;s: they were called out as fake in the court filings. But what about the remaining cases?
A properly cited case will include a reference to a case reporter, online database, or neutral citation. To confirm that the case exists, you would have to track down the purported reporter/journal/database and query whether the case exists at that location. There is a meta post that presents online legal research tools. Many universities and courts have public law libraries that have access to printed reporters and/or online databases.
There isn't to the best of my knowledge, any single document that tells courts to follow precedant or when and how to do so. Each State, and the Federal government, has a set of court rules of procedure. These will indicate, among many other things, the form that should be used in citing previous cases, but that is about form, not content -- about how to cite a case, not about when a court should or should not cite one. Some precedents are what are called persuasive. These are from other court systems: say a different state, or even another country. These also include rulings from other courts at the same level, say from a different district, or even from lower courts. Other precedents are binding. These are from a superior court to the one where the case is cited. In a state's lower court, rulings of that state's supream court are binding. In Federal district courts, rulings of the Court of Appeals for the same Circuit, and of the US Supreme Court are binding. In Federal appeals courts, rulings of the US Supreme Court are binding. They are also binding in state courts on matters where the US constitution is involved, or where Federal law supersedes state law. Prior rulings of the same court are strongly persuasive, but not strictly binding -- a court can overrule its own precedents when it thinks the law or justice requires this, although most courts are reluctant to do so. Or more often it can distinguish a previous ruling, saying, in effect: "that previous ruling is still valid, but this is a different case in such and such a specific way, so the result is different". Students in law school spend a good deal of time learning how precedents are cited, and how they should be used, learning what sorts of things are controlled by precedents, and how to find the precedents that apply to a particular case. When they become lawyers and then judges, they taken this body of learning with them, and use it in writing decisions, and opinions that explain those decisions. New law from the legislature can reverse previous court decisions, except in the case of decisions interpreting the constitution (federal or state). Amendments can change the constitution. Judges must adapt to such changes in the law. To a significant extent our system of precedent is a matter of tradition, going back largely to the common-law courts of England, although it has been modified by specific legislation in many ways, as well as by more recent court decision and practice. It is passed on in law schools, in legal apprenticeships of various kinds, and in individual court decisions.
The law is known to everyone in theory. But as various people are said to have said, In theory, theory and practice are the same. In practice, they are not. Starting from zero and actually finding out what law is applicable to your circumstances is not a trivial matter. To have an answer you can rely on you need to do the following: Find out what law calls it. Sometimes this is obvious, but not always. Go and find the law in question. Over the last 10 years this has got much easier. It used to mean going to your city library and looking up the relevant law. These days we have Google (other search engines are available). Find any other laws which might have bearing on the matter. This can be a long way from obvious (see below). Find any relevant appeal court cases in which something like your circumstances have arisen, and figure out how they relate to your actual situation. You may find that some of the laws which you read in Stage 3 have been ruled unconstitutional, or that the standard of evidence required to prove or disprove something about it has been set impossibly high, or that the penalties or damages have been set absurdly high or absurdly low. If you are in the US then maybe some of those precedents were set in other circuits, in which case you need to figure out what your local circuit is likely to do about it should the occasion arise. Make a calm, dispassionate decision about what to do about your situation. Many people find this extremely difficult. The answer might be life-changing. Under these circumstances making a good decision is very hard. Just to give you an idea about (3), suppose you are planning on importing something for your business. Here is a list of areas of the law you might fall foul of, off the top of my head and I've probably missed some: Tax. Trade in endangered species. Drug prohibition. Environmental protection. Biosecurity. Health and safety. Consumer protection. And that is just the criminal laws. Theories of civil liability can get really complicated. But OK, lets suppose you figure out the law, but despite your best efforts you find yourself in court (criminal or civil). Now in addition to all the law you find yourself enmeshed in a complicated bureaucratic set of rules, depending on the type of court and where you are (e.g. US rules of civil procedure). At this point you need to learn not just the rules but how to play the game they describe. Think of it like playing chess; learning how the pieces move is only the first step on the long road to becoming a competent chess player. And the legal system is like chess in another way; there are no do-overs if you make the wrong move. (Incidentally, anyone who says "Well lets just get rid of all the complicated rules and laws" is committing the fallacy of Chesterton's Fence. Just because you can't see why the rules are there doesn't mean there isn't a good reason). Or you could just hire a lawyer.
To determine whether an attorney is licensed to practice in a specific jurisdiction, you need to look up that attorney in the bar that applies to that jurisdiction. Some attorneys do not allow their information to be posted on the online lookup, in that case you would have to call the bar to confirm that s/he is licensed. I assumed you meant more than "case" in the legal sense above. For instance, if you want a Patent, you would need someone licensed to the Pat Bar. Cases they have worked on: You can use Google Scholar and select Case Law / the Jurisdiction you are concerned with and search for their name exactly (I would also limit the time frame.) The attorneys for each side are listed at the top. Some of the large cases have multiple pages of attorneys with their name on the case. Alternatively, if you have a subscription service to WestLaw Next, Bloomberg Law, or LexisNexis you can lookup the attorney and see case information as well, as well as court documents they have submitted in various cases - this allows you to get a glimpse of their writing style. Alternatively, you can visit your local law school's law library and, if they have public access, use the public terminals (at least my law school has these.).
The order of operations is important I assume that plaintiff filed for a Protective Order. To get this granted, the plaintiff has to allege some kind of wrongdoing and evidence of that. If the defendant responds, then the plaintiff can amend their filing. Then the defendant once more can respond to the allegations. If the plaintiff wants to amend the filing once more, they need to ask the court to be allowed to do so, and that opens the door for the defendant to answer once more. That's all history for the case presented: The court apparently found the evidence lacking and dismissed the application for a PO. Plaintiff can only file for reconsideration or appeal but not bring in new evidence at this point. Dismissed Cases are not automatically evidence A case that did not establish its burden of proof and was dismissed - especially with prejudice - has not established that the evidence in it is good. You have to ask each item to be admitted separately and re-establish that it is good evidence. A bulk filing &quot;I want to bring this case as evidence&quot; is generally denied unless you prevailed in that case. A dismissed case is one you didn't prevail in. Get a Lawyer! It seems like you are in serious need of legal counsel to clear up the situation. Contact a lawyer for at least a free consultation if you even have a case.
Special regimes For some kinds of questions there are special presumptions or forms of evidence that are specified by statute. For example, in Canada and the United States, registering a copyright creates presumptive proof that the copyright exists and is owned by the registrant. In Canada, breathalyzer results are conclusive proof of the blood alcohol concentration if certain conditions are met. Some of these regimes are not subject to challenge: they are legal facts even if they are not objectively true (e.g. the breathalyser results). Others create presumptions that can be overcome by contrary evidence (e.g. copyright ownership). The default: present relevant evidence, including testimonial evidence But outside of special regimes, you prove a fact by introducing evidence. The default is that all relevant evidence that bears on a material fact is admissible. Evidence is relevant when, if is were to be accepted, it would make the fact in issue more or less likely to be true. Evidence comes in many forms: testimony of the parties or witnesses, documentary evidence, physical evidence, expert opinion evidence. If you are wondering, &quot;How do I prove X?&quot; Ask yourself, why do you believe X? Or, how do you know X? Or, how has the event X left its mark on the world? Whatever has led you to believe X probably is the evidence that you would want to introduce to the court to help prove X. Perhaps you saw X: you can tell the court you saw X. Perhaps you took a photo of X: you can present that photo in court. Perhaps you have a receipt for X: you can show that receipt in court. Perhaps X is a proposition about your own actions: you can tell the court about those. Obtaining the evidence Evidence can be obtained from the other party during the discovery process, or from third-parties using subpoenas, subject to objections relating to relevance or privilege. Not all (potentially) relevant evidence is admissible However, some evidence will be inadmissible despite it being potentially relevant. I will only present a few categories, some very general and some more specific: hearsay (unless it falls within an exception to the hearsay exclusion), privileged material (unless it is a case-by-case privilege or a discretionary privilege and the person seeking to admit the evidence demonstrates to the judge that it should be admitted), sexual history evidence of a sexual assault complainant when it will be used to support an inference that the complainant is more likely to have consented to the sexual activity that forms the subject-matter of the charge or is less worthy of belief (this is because it has been recognized as not relevant for this purpose), material that was obtained in contravention of the Charter and where the court has decided that the remedy for the Charter violation is exclusion of the evidence (in the United States, there is stricter, exclusionary rule), there are many more. There are also some meta-rules about the evidence that may be used to impugn a witness's credibility, themselves at trial to provide evidence, but for now I am leaving those out of this fairly summary answer. Weighing the evidence The trier of fact (the judge or a jury) then is to weigh all the admissible evidence, including by weighing the witness and party testimony according to its credibility and reliability after testing through cross-examination, to come to a conclusion on the ultimate question(s) at issue.
Unless you are an ambassador or one of the US states, SCOTUS doesn't have original jurisdiction over your lawsuit, so they can't hear it either. If you've named all the judges of all the courts that do have jurisdiction, then one of them will handle it anyway, under the doctrine of necessity noted before. For cases that do fall within the Supreme Court's original jurisdiction, a jury trial is theoretically possible, but it appears it has not occurred since the 1790s, and only one has surviving records: Georgia v. Brailsford in 1794. See &quot;Special Juries in the Supreme Court&quot; by Lochlan F. Shelfer, Yale Law Journal 123:1, 2013-2014. Otherwise, non-jury original jurisdiction cases are usually delegated to a special master, a sort of &quot;contract judge&quot; who hears all the evidence and recommends a judgment that the full court typically rubber-stamps.
A case can be &quot;dismissed&quot; at (most) any time (however, the further along in the process a case is, the less likely a judge will allow a case to be dismissed without very good reason). A case can be dismissed with or without &quot;prejudice&quot;, which in this legal context means essentially &quot;finality&quot;. A case dismissed with prejudice cannot be brought again, while a case dismissed without prejudice can be refiled. (Compare the criminal law concept of &quot;double jeopardy&quot;, though as phoog correctly notes, &quot;double jeopardy&quot; only applies in criminal trials, while prejudice can be applied in both civil and criminal courts). Many cases are dismissed without looking at the evidence (or even having the evidence admitted to the record); this is called &quot;summary judgement&quot; or &quot;judgement as a matter of law&quot;. There are generally three cases when this happens: First, if the prosecution or plaintiff (i.e. the party bringing accusations) has &quot;failed to state a claim upon which relief may be granted&quot;, i.e. asked for something the court cannot grant. Second, is if the defendant can show, that even if everything alledged by the plaintiff is true, that the necessarily elements of the crime or offense have not been proven. Third, is if there are no facts in dispute, and only a disagreement on interpreting the law.
