In the United States, what decides whether a case should go to the state courts or the federal courts? The United States has a dual judiciary system with a state court system and a federal court system with the US Supreme court. If there is a person who is accused of breaking both state and federal laws because of an action(in this case, both state and federal laws agree with each other on the action being a breach of law) and they wish to take the matter to court, how do they decide which system to take it to?
State crimes must be prosecuted by state prosecutors in state courts. Federal crimes must be prosecuted by federal prosecutors in federal courts. hszmv's answer describes the DOJ's policy where there is overlap. In Indian country (this is a term of art in U.S. law), jurisdiction is much more complicated. In brief, there is often exclusive tribal jurisdiction when the alleged offence has an Indian accused and Indian victim. For a listed set of major crimes, jurisdiction is exclusively federal (except in states where that jurisdiction has been granted to the states), even if incorporating as federal law the state's definitions of particular crimes.
No The case was dismissed on procedural reasons. Like this. Well, perhaps not so pedantic but there are things that have to happen before the Supreme Court can get involved and they haven’t. For example, the Supreme Court only has original jurisdiction in a limited classes of case; if this isn’t one of those (and it isn’t) it has to be heard in a court that does and then get appealed up the chain. When they have, the court will make a decision on the merits.
Federal countries usually define the separation (and sometimes sharing) of legislative competencies in their constitutions. There will also usually be a "default" case for if the competency is not explicitly defined in the constitution. For example, in the United States, the default is to give legislative power to the individual states via the Tenth Amendment. If criminal law is left to the sub-national entities, then the nation can usually still enact a penal code with respect to its competencies (again, the U.S. is a good example). So, I decided to make this a mini-research project by checking the countries Wikipedia lists as federations. I wasn't able to find an explicit statement as to whether there were competing penal codes in most cases, but was able to find in which level of government the constitution placed criminal law. In some cases where there are "competing" penal codes, the constitution specified which level has supremacy, making for less "competition". Without further ado, here's what I've been able to find. Links are either to an appropriate Wikipedia page, or the part of the applicable constitution dividing the legislative competencies. Take these with a grain of salt.

“Like the Federal Rules of Criminal Procedure, the Federal Rules of Civil Procedure are as binding as any statute duly enacted by Congress, and federal courts have no more discretion to disregard the Rules' mandate than they do to disregard constitutional or statutory provisions.&quot; Chambers v. Nasco, Inc., 501 U.S. 32, 66 (1991). The civil and criminal rules of procedure are established by the U.S. Supreme Court, which promulgates them under authority delegated by Congress in 28 U.S.C. 2072. Some rules provide the courts more flexibility in their application than others, but the courts may not simply ignore them any more than they could ignore a Supreme Court precedent. For instance, in a case where the trial court dismissed criminal charges based on prosecutorial misconduct, the government appealed, arguing that the misconduct hadn't prejudiced the defendant, and Criminal Rule 52's &quot;harmless error&quot; rule requires the court to essentially ignore errors that don't effect the defendant's &quot;substantial rights.&quot; The defendant argued that the court's supervisory authority permitted it to dismiss the case to deter future misconduct. The Supreme Court reversed the dismissal, agreeing with the prosecution that a court has no authority to dismiss the case based on error that the rules of procedure order it to ignore: Rule 52 is, in every pertinent respect, as binding as any federal statute. &quot;Courts have no more discretion to disregard the Rule's mandate through the exercise of supervisory power than they do to disregard constitutional or statutory provisions through the exercise of such power.&quot; Bank of Nova Scotia v. United States, 487 U.S. 250, 250 (1988). Other courts have concluded that this standard applies to the Federal Rules of Civil Procedure, as well. See, e.g., Stone Container Corp. v. United States, 229 F.3d 1345, 1354 (Fed. Cir. 2000) (&quot;[T]he Federal Rules of Civil Procedure, like the Federal Rules of Criminal procedure, are “as binding as any federal statute.”); S.E.C. v. Selden, 484 F. Supp. 2d 105, 107 (D.D.C. 2007); Sieb's Hatcheries, Inc. v. Lindley, 13 F.R.D. 113, 119 (W.D. Ark. 1952); Westland Oil Co. v. Firestone Tire &amp; Rubber Co., 3 F.R.D. 55, 56 (D.N.D. 1943). tl;dr: The Rules are rules of procedure. They must be adhered to.
Is A or B subject to Canadian employment law? Canada and the relevant province(s) will decide in their courts if Canadian or US law applies. The USA and the relevant state(s) will decide in their courts if Canadian or US law applies. It would be open to the employee to bring an action in any relevant court; the court will then decide what law applies and if they have jurisdiction - that is part of what sovereignty means! A Canadian court can decide a matter using US law and vice-versa. Things that the court would take into consideration are if the company did business (outside this single arrangement) in Canada or was US exclusive, the number of other trans-national interns, if the arrangement was seen as a device for avoiding employment obligations in either jurisdiction. If one is subject to Canadian law then they both are. Will either party get into trouble with the Canadian government? Assuming that the arrangement is subject to Canadian law then the company would be obliged to pay wages and may be subject to fines for not having done so. If so, what enforcement (and/or punishment) mechanisms does the Canadian government have at their disposal to enforce their employment laws against A or B? B - nothing; they have not broken the law. A - an order to pay wages and fines. Enforcement may require a judgement in a US court; either by bringing the case in one the first instance or applying to have a Canadian judgement given effect in the US. Edit The OP has added the proviso that the document states that it subject to US law and jurisdiction. If it just says that, it is prima facie invalid - a contract cannot exclude the jurisdiction of any court and an attempt to do so renders it unlawful. However, if it said that it was subject to the non-exclusive jurisdiction and law of, say, Wisconsin, then a Canadian court would consider the parties intent and the relevant Canadian national and provincial law and might decide that the proper forum is a Wisconsin court and refuse to hear the complaint. Things they will consider are that there will be Canadian and provincial laws that cannot be excluded by contract, the hardship changing the forum will have on the plaintiff or defendant, if the result (assuming the facts are proven) would be demonstrably different in a US vs. a Canadian court etc.
State legislation can be invalid due to inconsistency with either the U.S. Constitution or the state's constitution. State legislation can also be inoperative due to pre-emption by conflicting and valid federal law.
No. A plaintiff may travel to the defendant's jurisdiction to file suit if desired. Nobody usually does this, though, due to travel and logistical considerations. The defendant is the one who decides whether to challenge jurisdiction. Good contacts will include a forum selection clause which would lay out what happens where in the event of a dispute. And this can be anywhere, it is not limited to the locations of the plaintiff and the defendant. N/A.
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.
