What is the difference between juridiction and law in a specific region? The Wikipedia page of jurisdiction does not help me much to comprehend the concept. In my understanding it basically &quot;law in specific region&quot;. I understand the concept is much more than that, but I don't know exactly what. Can you give some examples or analogies? And is there anything that is shared between all jurisdictions?
&quot;Law&quot; refers to rules; &quot;jurisdiction&quot; refers to the situations in which those laws apply. For example, the United States Constitution is the supreme law of the United States of America. But for the most part, it only applies within the territorial jursidction of the government that enacted it, i.e., places inside the borders of the United States, or to those over whom the United States has personal jurisdiction, i.e., United States citizens, permanent residents, those currently inside its borders. So the United States Congress could pass a law outlawing the sale of dogs, but it would have no effect on dogs in Canada, as Congress has no jurisdiction over dogs in Canada. Similarly, if a Canadian terrorist (the most dangerous kind, really) launched a missle over the border into the United States, the FBI could not arrest him in Toronto, as they lack jurisdiction to enforce the law outside the United States. &quot;Jurisdiction&quot; is also a concept that limits the powers of courts to hear cases. &quot;Subject matter jurisdiction&quot; refers to limits on the types of cases the court may hear, and &quot;personal jurisdiction&quot; refers to limits on whose cases the court may hear. For instance, if the New York Legislature established a small-claims courts to resolve claims for less than $10,000, your case might be dismissed for lack of subject-matter jurisdiction if you sued someone for $10,001, or it might be dismissed for lack of personal jurisdiction if you sued someone who had no connection to New York. These explanations are admittedly incomplete and imprecise to provide a basic understanding of the concepts, rather than an overwhelming -- and boring -- exposition of the precise meanings of these terms.
As much as they like Most pieces of legislation have a “dictionary” detailing, for the purposes of that legislation (or generally) what specific words and phrases mean. This can broaden (or narrow) the definition compared to how they are used in normal English. The purpose of this is not to set a trap for the unwary, although this may happen, but to introduce precision and to allow a short defined term to be used in the drafting rather than having to explain what is meant verbosely every time it’s used. Of course, they can’t redefine terms so that they give themselves jurisdiction when they otherwise wouldn’t have it. For example, in australia, the Constitution gives the Federal Parliament the power to make laws about, among other things, “external affairs”. A law that tried to define “external affairs” more broadly than the Constitution does (which it doesn’t, so we fall back on what it means in English) would be invalid.
why do they sometimes specify the federal law as well as the state/provincial law? Isn't it redundant? Not necessarily. The contract might be entered and/or performed in a different country, whence mentioning only the Canadian provincial law does not override the other country's federal law (or that country's &quot;supra-provincial&quot; equivalent). Mentioning Canadian federal law removes --at least on paper-- the ambiguity of which law applies for matters beyond the scope of Canadian provincial law. In such scenarios, portions or the entirety of the provision might be null and void. For instance, an employment contract might establish waivers which are void or perhaps even unlawful under the legislation of that other country. Please note that in general a copy/paste of sample clauses is strongly discouraged unless the parties fully understand their meaning and implications.
You can use academic sources when arguing in court if you like, but be aware of the following: Academic texts are not primary sources of law in Jamaica. What is in them may be persuasive but does not bind a court in the same way as statute law or case law. Sometimes, it's appropriate to cite works of legal scholarship to flesh out an argument. If the book contains a succinctly-phrased statement that matches what you want to prove, but prior case law isn't quite as neatly applicable, then you might cite both - subject to points below. Citing the book alone is weaker. At other times, when there is authority on both sides of a point, you might find academic argument tipping the balance, but again not to be used in isolation. Whether a text is persuasive may not be obvious, especially for older works. Sometimes, perhaps often, the law has changed since the book was published. Don't assume that an old book by a famous author will automatically be revered. You can check to see if newer books say something different from the older one, and in general start your search looking backwards from now in order to identify the current state of the law. It is more common these days to see references to current editions of textbooks than comparatively ancient authorities, no matter how illustrious the name of Blackstone might be. If a point of law is not actually contested, then there is no need to argue about it. It can form part of the background material that is agreed on between the parties. Basic principles of the way contracts work don't need elaboration or authority. Judges would prefer to have you limit the number and range of authorities you bring in, because they only have so much time in their day and they don't want to struggle through a lot of unnecessary background reading. In a skeleton argument, the strong preference is for only one principal authority to be mentioned in support of each point of law. You can mention a recent decisive case rather than reciting the entire history of case-law on the topic, and you don't need to include cases where a well-understood precedent was applied without difficulty. It may be that a textbook brings you to the relevant statute or judgement but then that is what you need to cite, not the textbook itself, especially if it simply quotes or restates what is found in the primary material. For filing court documents in general, pay close attention to the Civil Procedure Rules and the Practice Directions, including PD No. 8 of 2020 on the format of the judge's bundle. If the judge is annoyed enough about non-compliance with the court's rules about submissions, then various sanctions are available to them. For example, they can refuse costs on the legal research that led to the preparation of the submission. In correspondence, which I think you allude to, you can be more free than when dealing with the judge's bundle. In a letter to the opposing party you can certainly bring in additional references that you think would be helpful to you as a matter of rhetoric and argumentation. Do note that doesn't mean it is a good idea to make correspondence too aggressive or lengthy. For one thing, a judge can end up reviewing the correspondence and will notice whether or not you are making a good-faith effort to resolve the matter, or at least identify the salient issues to bring to the court.
I can't do much better than the opening to Wikipedia's article on this: The contemporary legal systems of the world are generally based on one of four basic systems: civil law, common law, statutory law, religious law or combinations of these. However, the legal system of each country is shaped by its unique history and so incorporates individual variations. I believe that there are about 196 sovereign nations in the world so that gives 196 national systems. Many of these have sub-national jurisdictions (e.g. The USA with 50 states plus military law) so this total is at least several hundred and may run up to 1000. In addition there are systems of supra-national law such as maritime law, war crimes law and supra-national jurisdictions like the EU. So, short answer: lots. The correct terminology for a system of law is a jurisdiction. Note that many activities will be subject to multiple jurisdictions.
(The original title of your question suggested you might think that federal circuit precedent binds state courts: it generally does not, even on matters of federal law.) But regardless, Congress would not be able to legislatively lower the constitutional floor. If a certain police act is prohibited by the Constitution, Congress cannot legislatively allow that act, whether in a single state or uniformly across all states. That means that if the Fifth Circuit has decided that the use of some new investigatory tool is a search under the Fourth Amendment, no law that Congress passes could affect that holding. When congress creates laws that result in different effects for different people (e.g. people in Texas vs. people in Florida, as in your hypothetical), the distinction must be rationally related to a legitimate government purpose. Many of the enumerated powers allow for local distinction, some prohibit it. Some examples where Congress has distinguished between states include: localized agricultural programs, time zones, voting rights protections, and various others listed in ohwilleke's review. Some distinctions between states could also intrude on principles of federalism and state sovereignty (e.g. the Supreme Court has said that the Voting Right Act does this). Maybe I am unimaginative, but I cannot think of a legitimate federal government purpose that would call for the powers that police have against the people to vary from state to state. Any such variation would have to come from the states themselves: from their state constitutions, or legislative choices to provide heightened protections. Discord between circuits is problematic (see a list of examples of existing splits), and this is why the Supreme Court of the United States will often hear an appeal where there is a circuit split on a question of constitutional rights.
It is certainly possible for the same action to break multiple laws, and be chargeable as multiple crimes. For example, shooting and killing someone may be assault, assault with a deadly weapon, and murder all at the same time. For a different example a person who simply omits to file an income tax return may be guilty of both failure to file a required return, and failure to pay tax due, and in some cases failure to par required estimated tax due as well. For yet another example, driving well above the speed limit may be a violation of the speed limit law, and also careless driving, and possibly also reckless driving. In the first case the assault etc may be lesser included offenses in the charge of murder. That means that they are automatically available to a jury (or judge) trying the accused, who can convict on one of the lesser included charges if they do not convict on the primary count. For the more general case, I don't know of any special term for the situation. It is not usual to have law A which says "do not do X", and also law B which says "you must follow law A". There is no general principle against having such redundant laws, nor is there, in the US, any Constitutional rule against such laws. But legislatures do not normally bother to enact such redundant laws. Laws which will sometimes overlap in their coverage, but in some cases do not overlap are common.
The interpretation of state rules of civil procedure is a matter purely for state courts. Whether a state procedural rule (or even substantive approaches to jurisdiction) violates federal law, including the U.S. Constitution, is a question of federal law, but state courts are still competent to answer such questions that arise in the process of state litigation, subject only to precedent from the Supreme Court of the United States. I may be starting to just repeat things now, but even if the legal issue you're interested in (the extent to which trial courts are divested of jurisdiction during non-frivilous interlocutory appeals in matters controlled by the FAA) is substantive or jurisdictional rather than procedural, Federal circuits do not bind state courts. However, the Supreme Court of the United States can provide binding prcedent on federal law that state courts must apply. I could see the reasons in Coinbase being written broadly enough to apply to both state and federal proceedings.
