Military Law and Double Jeopardy? We all know, that Double Jeopardy applies in the US, stopping one from getting tried twice for the same act... by the same type of court. Double Jeopardy does obviously not apply to being tried by the state and the federal court system, where you can be convicted for drug smuggling by both the Federal and the State court as you broke both laws with the same act. Sometimes one of them is using the result of the other as evidence and to fast track the trial. With the right setup, we know that up to 4 states, 2 tribal governments, and the federal court system could get you for murder on the Four Corner's Monument. How would being in the US Military add to that? Could a military court take the same act (in the example murder, but possibly also noncapital crimes) and try you for the same or different charge to further increase the punishment?
Double Jeopardy does obviously not apply to being tried by the state and the federal court system, where you can be convicted for drug smuggling by both the Federal and the State court as you broke both laws with the same act. This is true, and the answer to your question comes in the reason this is true. The exception to double jeopardy you're referring to applies to charges from separate sovereigns. When considering whether two entities can both charge someone, you trace back each of them to the sovereign power that gives them their authority. States are considered sovereign, as are Indian tribes with respect to crimes committed by Indians (although for certain serious crimes like murder, Congress arguably stripped tribal courts of jurisdiction with the Major Crimes Act). The United States is of course sovereign. The military is not sovereign. Military charges are based on the sovereignty of the United States, so double jeopardy applies between military and civilian federal courts. Likewise, US territories (and DC) are not sovereign and have criminal jurisdiction based on the sovereignty of the United States, so territorial (and DC) charges are subject to double jeopardy with each other, with military charges, and with civilian federal charges. That said, double jeopardy only applies if the charges represent the same offense. The UCMJ has offenses with no civilian analog. If you're charged with murder in civilian federal court and mutiny under the UCMJ, those are two different crimes.
No. Arizona tried passing a law that, among other things: criminalized failure to comply with federal alien registration requirements, criminalized working without being authorized to work in the United States, and authorized state officers to arrest aliens without a warrant if they had probable cause that the alien had committed a crime that made them deportable. All three provisions were struck down in Arizona v. United States. The federal government has &quot;occupied the field&quot; on most immigration issues. That means they've regulated it so extensively that there is zero room for states to act independently. One of Arizona's laws that was struck down exactly duplicated a federal criminal statute, but even that went too far by allowing the state to apply its own enforcement priorities and prosecute cases the federal government would not. If a state made it a crime to be unlawfully present (which is not a federal crime), that intrudes even further on the federal immigration scheme. This doesn't mean a state can't alert the federal government to people who are unlawfully present. It doesn't necessarily mean state officers can't arrest for federal immigration crimes: a previous Ninth Circuit decision held that Arizona officers could arrest for federal immigration crimes on the same basis that they could arrest for state crimes, and the Supreme Court in Arizona v. US explicitly didn't address the question. However, if state officers make an arrest for a federal crime, the federal government still gets to decide whether or not to prosecute. What you're asking about would remove that federal control, so it is preempted by federal law.
The Seventh Amendment's jury trial provision does not apply to the states. The Bill of Rights does not inherently restrain the states at all, merely the federal government. The Fourteenth Amendment does restrain the states; notably, it forbids a state from depriving any person of life, liberty, or property without due process of law. Courts have read into "of law" the added requirement that the law be compatible with the fundamental rights that are implicit in the concept of ordered liberty; this means that most stuff that would violate the Bill of Rights if done by the feds violates due process if done by the states. However, not all provisions of the Bill of Rights have been incorporated (i.e. applied to the states); the requirement for a jury in a civil trial is one of the few that hasn't been incorporated, because courts do not consider it a fundamental right (merely one protected in the federal courts). Now, many traffic tickets are actually misdemeanor offenses, and a jury-trial requirement for crimes is incorporated. However, even for federal offenses, the courts have generally found that the Constitution doesn't require jury trial for petty crimes (those with a maximum sentence under 6 months).
Absent newly enacted law in response to the end of the separate sovereigns doctrine, the first case to which jeopardy attaches (generally speaking when a jury is sworn and the first item of evidence is presented to it) would bar subsequent prosecutions, without regard to whether it arose in state or federal court. It would be a race to the court house rule. This is how it works if there are multiple prosecutions within a state, for example, one commenced in a municipal court that is not part of a state court system, and another commenced in a state court of general jurisdiction.
Many times. See pages 4 and onward here. The 11th circuit (which includes FL) recognizes sentencing manipulation but not sentencing entrapment. The one example from the 11th circuit in that document (US v. Ciszkowski, 492 F.3d 1264) was an unsuccessful claim of sentence manipulation, but it shows the analysis that goes into deciding these types of claims. They say: While our Circuit does not recognize sentencing entrapment as a viable defense, we do recognize the outrageous government conduct defense, and we have considered sentencing manipulation as a viable defense. ... Ciszkowski, however, has not met his burden of establishing that the government's conduct is sufficiently reprehensible to constitute sentencing factor manipulation. Government-created reverse sting operations are recognized and useful methods of law enforcement investigation. Sanchez, 138 F.3d at 1413. The fact that law enforcement may provide drugs or guns essential to a willing and predisposed offender does not necessarily constitute misconduct. We have previously declined to find that the government engaged in prohibited sentencing factor manipulation in other similar contexts.
You have asked about "United Kingdom", but I can only answer about England and Wales; the law in Scotland is very different (rather more different in some respects than the difference between E&amp;W and the State of New York). There is no time limit per se on manslaughter charges; if the police find evidence for a manslaughter charge after 80 years, there is no difficulty (in principle) in bringing a charge against the now-centenarian (provided they are competent to stand trial, and they can get a fair trial, and so on). However, in the case you mentioned I would have thought the major problem would be a defence of autrefois convict - in other words, the defendant can (usually) only be charged once with charges arising from a particular set of facts. It is just possible that the subsequent death constitutes a new fact which allows a new prosecution. On the other hand, the rule for murder used to be that if the victim survived a year and a day then it wasn't murder (even if they then died of their injuries). Finally, the case certainly would not be reopened with a charge of manslaughter. It would be "causing death by dangerous driving", which is a very different offence. Edit My thanks to ohwilleke whose comment about the "year and a day" rule prompted me to do a little research, and discover the Law Reform (Year and a Day Rule) Act 1996. Section 2(2) clearly covers the present case (in both legs), and says that the perpetrator can be re-prosecuted, but only with the permission of the Attorney General. The act is very brief, and I encourage you to read it all. (And incidentally, does not apply to Scotland.)
Constitution of the USA, Article IV, Section 1: Full Faith and Credit shall be given in each State to the public Acts, Records, and judicial Proceedings of every other State. And the Congress may by general Laws prescribe the Manner in which such Acts, Records and Proceedings shall be proved, and the Effect thereof. and the Commerce Clause (Article I, Section 8, clause 3): [The Congress shall have Power] To regulate Commerce with foreign Nations, and among the several States, and with the Indian Tribes; SCOTUS has found the former to mean that states that do not allow same-sex marriages in their laws must recognize same-sex marriages registered by other states - Obergefell v. Hodges. Maybe one could argue that driver licenses are not equivalent among states, but I would expect judges (SCOTUS) to require a very well reasoned explanation. For example, maybe Alaska could refuse to recognize licenses from Florida because Florida drivers do not know how to cope with snowed roads. But even in that case Alaska probably would need to produce data showing that these measures aim to serve the public interest (avoid accidents) and that there are no other ways of getting the same result. OTOH the Commerce Clause has been successfully used to avoid states mandating racial segregation of travellers, so it is quite reasonable to see it being used to prevent a state from trying to limit the mobility of citizens from other states (again, in the supposition that the state restricting it cannot show a compelling reason to do so). AFAIK, only the Federal Government could invoke the Commerce Clause; I would expect a lot more people (in your example, the PA government or maybe even any PA driver) would have standing.
Short Answer No. Double jeopardy of the Fifth Amendment to the United States Constitution prohibits someone from being prosecuted more than once for the same factually specific crime (i.e. "the same offense"). The Double Jeopardy Clause of the Fifth Amendment provides: “[N]or shall any person be subject for the same offence to be twice put in jeopardy of life or limb.” The original acquittal was correct, because it was for a crime that did not happen. The later trial is for a different crime that actually did happen at a different time. In the same way, an acquittal for a DUI committed on Tuesday does not bar prosecution of the same defendant for a different DUI committed on Thursday. So, double jeopardy does not apply in the scenario presented. A Similar But Harder Case The analysis would be trickier if: A shoots B. A is tried and acquitted for the murder of B. B was only presumed dead but was actually alive. After being acquitted for Bs murder, B dies of the gunshot wound from A in (1). A is later arrested and tried for Bs murder (a second time). This is a much trickier question, because A was actually tried and acquitted of a crime that hadn't been completed at the time of trial, but in which A's involvement had terminated at the time. (To make it even more complex if you are inclined, in a first degree kidnapping case, the death penalty applies unless the defendant can prove the affirmative defense that the victim didn't die, and a first degree kidnapping acquittal would probably not bar a later murder conviction because the offenses have elements sufficiently different from each other, even though the death penalty or life in prison without parole sentence for that offense is based on the conclusive presumption that the victim died in law, rather than in fact.) Issue Preclusion This might depend upon the nature of the evidence at trial - if A did not raise the failure of the prosecution to provide corpus delecti (i.e. a dead body) or the misidentification of an alleged victim's body as a defense and instead, for example, argued an alibi defense (e.g. he was in jail at the time of the alleged shooting). This narrow fact pattern would be a particularly close question and I wouldn't be surprised to see a court deviate from the usual precedents and general rules under these circumstances. There is a substantial body of case law on whether prosecution for a crime with elements A, B, and C bars prosecution for a crime with different elements arising from the same facts and circumstances (e.g. if acquittal of a lesser included offense whose elements must all be proved to convict on the more severe offense provides double jeopardy protection), that wouldn't be directly applicable in my alternative scenario because the offense tried the first time and the second would have exactly the same elements. This depends upon when a concept analogous to the principle of collateral estoppel (also known as "issue preclusion") in civil cases, in which facts previously litigated can bind a party in a later lawsuit, with or without constitutional double jeopardy dimensions, applies in criminal cases. As a general rule, there was historically no doctrine of collateral estoppel in criminal cases as noted in a 1967 law review article. But, the U.S. Supreme Court has also adopted a limited version of the principle of collateral estoppel under the guise of the double jeopardy clause in criminal cases as it noted in Yeager (discused below) a few years after that article was written. [I]n Ashe v. Swenson, 397 U. S. 436 (1970). . . we squarely held that the Double Jeopardy Clause precludes the Government from relitigating any issue that was necessarily decided by a jury’s acquittal in a prior trial. The hard question is determining what a jury's acquittal "necessarily decided" in particular facts and circumstances, given that a jury verdict in a criminal case typically only determines if the jury convicted, acquitted, or hung on each of the charges presented to it in the indictment and not dismissed before tiral. This analysis requires the court to assume that the jury acted rationally, even if extraneous facts allow us to know that it did not act rationally, and to determine that a prior acquittal was logically inconsistent with a new conviction. In Yeager v. U.S. (2009), however, the U.S. Supreme Court interpreted Ash v. Swenson narrowly. It held that hung juries on counts should be ignored for constitutional purposes as if that the trial of that count never happened. When Is A Murder Committted? There would also be a question of when the crime of murder is committed (i.e. when the acts are taken or only once someone dies). Generally, murder is not a complete crime until someone dies. For example, if you were prosecuted for murder before someone died and acquitted because they were alive, you could be prosecuted again for murder later if they died of their injuries. (The more usual case is that someone is tried and convicted of assault, then the victim dies, and they are retried for murder, which is allowed since a conviction for assault is not logically inconsistent with a conviction for murder.) Similarly, if you were convicted of murder after a fair trial and presented the live body of the victim as newly discovered evidence, there is a good chance that you could have the original conviction vacated. If, however, you were convicted, and the Court found that you knew that the victim hadn't died at the time of trial, but you did not raise the fact that the victim wasn't dead, it isn't clear if you could have the original conviction vacated because it was a fair trial and you knew evidence sufficient to get yourself acquitted (which you may have refrained from presenting to avoid conviction on a lesser charge like kidnapping or aggravated assault), and the status of an "actual innocence" grounds for vacating a conviction after trial is hotly disputed, conservatives like the late Justice Scalia generally say "no", liberals generally say "yes", moderates like to say "yes" but make it almost impossible to establish except in rare cases like one where a live person walks in when there was a murder conviction for killing that actually living person. Obviously this doesn't come up all that often because usually prosecutors don't bring murder cases until they find a body and identify it and aren't in a rush to do so because there is usually no statute of limitations for murder. Conclusion In The Harder Case My overall conclusion is that double jeopardy would not apply even in the much closer case. This is because a belief that the victim was not dead could have been a basis for the original verdict notwithstanding a presumption to the contrary. The jury knows that a death is a element of murder and might have acquitted not based upon the reasons presented to it at trial but based upon their own personal view that the failure to present a body left them with reasonable doubt for some reason or another, which is a perfectly plausible scenario. If this happened, an acquittal the first time and conviction the second time wouldn't be inconsistent, even if no one argued about a lack of a body in their trial presentation. Ironically, if A was acquitted of aggravated assault of B in the first trial, that would be far more likely to bar a conviction when B later dies, than an acquittal from a charge of murdering B, because murder is logically inconsistent with an acquittal of aggravated assault in most circumstances, but a previous murder acquittal based upon lack of proof of a dead body is not inconsistent with proof of a later death. But, this would still be a close case that could come out either way on the double jeopardy issue. A court could conceivably argue that if the death of B was not contested at trial, that the first murder acquittal would be inconsistent with a murder conviction upon the death of B later on from the events that formed the basis of the first prosecution. Tactical Considerations Of course, even if prosecution of A for B's murder the second time was not be barred by double jeopardy, it is still likely that the prosecution would agree to lesser charges or not prosecute because the first acquittal showed it was a weak case, and the fact that A would now also be able to argue that the gunshot was not the proximate cause of B's death (and that it was instead, for example, due to medical malpractice or was a de facto suicide due to refusal of adequate treatment). Scope Of Analysis This reasoning would apply anywhere in the U.S. and is not specific to a particular state or territory as double jeopardy is a principle of U.S. Constitutional law that applies directly in federal courts (including the courts of territories and commonwealths) and indirectly through selective incorporation against the states via the 14th Amendment.
