Does the maxim &quot;Expressio Unius Est Exclusio Alterius&quot; apply to the rules for dating my teenage daughter? Non-lawyer here. Someone I know who IS a lawyer says that the maxim &quot;Expressio Unius Est Exclusio Alterius&quot; governs conduct everywhere, even in non-legal settings. I asked if it governs the conduct of teenage boys trying to date my teenage daughter. He said that absolutely it does, and that ignorance of the law is no excuse. Frankly, I have no idea what he's talking about. What would it even mean for this maxim that he called a &quot;canon of construction&quot; even to apply here?
Your lawyer friend is misguided Casual conversation and writing are not subject to any maxims of interpretation - the words mean what the speaker/writer says and what the listener/reader understands and these may be different things. In a conversation about restaurants, there is no implication that the places not mentioned are not restaurants or don't exist. Even if I were to write a published magazine article called &quot;The 10 best restaurants in the world&quot;, there is no implication that no other restaurant can possibly be better than those 10. This applies even in business settings. For example, this is the Petbarn logo: It has images of dogs, fish, cats, and birds. By your friend's argument, it would be unlawful for them to sell products for the care of pet snakes or lizards since they aren't on the sign? Or, for that matter, to operate from a building that is not a &quot;barn&quot;? Finally, your friend is wrong even in legal interpretation. There are many ways of contract and legislative interpretation that are or have been in use in every jurisdiction. &quot;Expressio Unius Est Exclusio Alterius&quot; is one maxim of interpretation but it may be in conflict with others. For example, if a regulation on aircraft listed various types of aircraft but didn't mention helicopters but nevertheless had an entire section devoted to rotor maintenance the &quot;Rule against surplusage&quot; would require that helicopters be included. In any event, modern courts tend to take a more holistic view to interpretation and the use of individual maxims is optional.
No The general common law rule is that a lawsuit requires an actual dispute. This is a contrived dispute with no real-world relevance. With apparent (or even actual) authority to act on behalf of A, you assisted B with making copies. The moment you contrived this scheme and set it into motion, you consented on behalf of A to allow B to use the materials. It is like paying someone to slip and &quot;fall&quot; on your sidewalk so they can sue you. There is no actual dispute, and volunti fit non injuria.
Very few terms have a single "legal" definition or meaning that applies to all laws, and can be looked up as if in a dictionary. Rather, when a specific meaning is needed in connection with a particular law, that law will include a definition. But that definition will often not apply to the use of the same term in other laws or other contexts. Here I suspect that the OP has found the definition section of a US Federal law regulating commercial transport in interstate commerce. Obviously in such a law, those terms would be defined in the context of commercial transport. That does not mean that the same meanings will be applied in other laws. Driver's licenses and other traffic and motor vehicle regulations are largely matters of state law in the US. Definitions from a federal law, or indeed any law but that state's Motor Vehicle Code (or whatever a given state calls such a body of law) will simply not be relevant. The argument sketched in the question simply does not follow.
While it is true that jury instructions are typically less than optimal, it is ideological hyperbole or cynicism to claim that instructions are purposely confusing. The ultimate source of the confusion is that the legal system has to assume (pretend) that it has clear-cut rules that any reasonable person can easily understand and automatically apply. In order to maintain uniformity of the law, there is an externally-defined instruction that a judge may read (rather than giving his personal spin on what "reasonable doubt" means or what the relationship is between "reasonable doubt" and convicting a defendant). Once the relevant body of government (committee of judges and lawyers) has established the apparently correct formula for expressing the applicable legal concept, they don't mess with it, until SCOTUS overturns decisions enough times based on crappy instructions. Legal professionals are trained to carefully scrutinze language so as to achieve a single interpretation of a given clause (never mind the fact that there turn out to be many such interpretations). Since they can apply these interpretive rules, it is assumed that anyone can apply them. But in fact, we know that people don't just use literal semantic principles to reach conclusions – but the law resist pandering to that imperfection in human behavior. There is a huge literature on problems of jury instructions, some of the better of which relies on psycholinguistic experimentation to establish that a given instruction is confusing or gives the wrong result. See for example Solan's "Refocusing the burden of proof.." (and references therein) that addresses the problem of the "beyond a reasonable doubt" instruction, which has the unintended consequence of implying that the defense has an obligation to create a doubt (which is not the case, and allows conviction if there is the weakest imaginable evidence which hasn't been refuted). But who gets to decide what the improved instructions should say? The instructions have to correctly state what the law holds (where "the law" means not just statutes, but the trillions of relevant court decisions and applicable regulations). Thus there is massive inertia, and improved jury instructions will not come about quickly.
There are a lot more differences than this, but if your teacher sums up what he/she means by that sentence. Here, specifically, in Civil Law, the decision of the courts must comply with the laws as enacted, which means there are specific statutes required to make something illegal. Common Law features Stare Decisis which basically means that if Case A is decided in one way, and Case B is a similar Case to Case B, Case B must yield the same decision for all cases in that jurisdiction and lower courts below that court. This means that while statutes (laws) can be made by a legislature, the courts can "make law" by deciding cases. For example, some States in the United States and England and Wales only recently (within the past 30 years) adopted an actual law that made murder illegal? Prior to that murder was illegal under Common Law Murder that had been based on precedence from bazillion cases before that said it's illegal. Nobody bothered to write it down in an actual law. There are several other big differences such as Inquisitorial vs. Adversarial nature of courts, how and when punishments are decided (The famous "Just following Orders" Defense was given in part because of this difference and a lack of understanding over it.), who is the trier of fact vs. who is the trier of law, but as far as what is "Law" this is a good single summation of the difference in a single sentence. But it really shouldn't be condensed to a single sentence.
Law, as such, is not a moral or a philosophical construct. It can be based on moral constructs and often it is. And, of course, the process of writing laws is often informed by philosophy. But law as such is neither one of those. Law is a set of behaviors which are known to be acceptable to the powers &quot;that be.&quot; This maybe an unsettling idea. But it is true nonetheless. The phrase that summarizes this is &quot;any law is only as good as its enforcement mechanism.&quot; What makes it seem untrue is that in the modern tradition laws are written down. And, when there is a need to resolve doubt as to whether something is illegal or not, they are carefully considered through a deductive process. Within countries, there is little question who &quot;the powers that be&quot; happen to be. But when it comes to laws governing actions between nations, it is more complicated. Yes, treaties make it clear, ahead of time, what types of expectations exist. Predictability (even in war) allows for long-term planning. And even laws of war are usually followed because wars are fought with the expectation that at some point they will end. And predictability allows to set end-goal conditions. Notably, entities which have no clear end-goals in sight are the ones least likely to follow any laws. The idea of any group of countries sitting in court of another group of countries is mostly a political theater. There is no possibility of predictable outcomes from entities which have not made commitments to those outcomes. So whether some countries have to follow &quot;laws&quot; set out for them by other countries (or non-government entities) is largely a result of those countries or entities being in positions of power to dictate their will. This is not the same as international laws being strictly de facto. Agreed-upon restrictions and restrictions which have been dictated from the top-down, by those with more power, are de jure because they create predictable boundaries on behavior. De facto restrictions are the ones which have come to be the case without any prior agreement or fiat.
I'm no expert, but I had assumed this clause was present in case of the following situation. Joe is arrested for a robbery of a London bank. Joe says nothing under questioning. At trial, Joe's defense is that at the time of the robbery, he was in Sheffield drinking beer with his brother. On the basis of common sense, a jury could think: "Surely if Joe were really innocent, he would have told the police of his alibi at the time he was questioned, and saved himself a lot of trouble. Since he didn't do that, maybe a more likely explanation is that he wasn't actually in Sheffield, but that sometime between arrest and trial, he came up with the idea of faking an alibi in Sheffield, and convinced people to testify falsely to that effect. Yes, that does seem more plausible. So we are not going to give much credence to Joe's supposed alibi." So it really would be the case that not mentioning the alibi during questioning would harm Joe's defense at trial. The warning, then, is intended to keep Joe from doing this inadvertently. If Joe's alibi is genuine, but out of a misguided desire to exercise his right to remain silent, he doesn't mention it during questioning, he may accidentally increase his chances of being wrongly convicted. Everybody has an interest in avoiding this.
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.
