If you are serving a life sentence, die, are legally declared dead, and are brought back to life, are you now free? Apologies if this is too hypothetical and not allowed. I'm not trained in law, but am curious about the following question: If you are sentenced to 1 life sentence, die, are legally declared dead, and you are brought back to life (not going to address how, but who knows, maybe it's something that could happen in the future), will you now be free, having technically served a life sentence? You were in prison until your death. Would the second interval of life be considered the same life, and so imprisonment should continue, or would it be a second life? I understand that there is probably no precedent for this and so any answer may just be speculation. But if you were the judge, what would your opinion be? As a follow up question, if the answer is that your second life would be free, then what if you have 2 life sentences? Would you serve another life sentence upon your second life? In that case, would the second life sentence be considered served to completion upon your second death, in which case you would be free if you were lucky enough to be revived once more?
If you can be revived, you are not legally dead. To be declared dead you must be in cardio-pulmonary failure and have all attempts at resuscitation cease or be brain dead - no one has ever recovered from these conditions. Notwithstanding, if you are declared legally dead and show up alive, that declaration can be nullified i.e. you were never dead.
There is no absolute rule in such cases. It is often a matter of negotiation between the state and federal authorities, and failing agreement, a matter of which authority has the prisoner in custody. Often the question of which crime is more serious or carries a longer sentence is an issue in such negotiations.
No Let's consider a similar scenario. If you made a beverage which poisoned a number of people, would you be absolved of liability because you gave it away for free? Of course not. As there is no contract between you, they would have to bring an action against you in the tort of negligence or negligent misstatement OR under consumer protection law. To succeed at tort they would need to prove that you owed them a duty of care; from Donoghue v Stevenson "You must take reasonable care to avoid acts or omissions which you can reasonable foresee would be likely to injure ... persons who are so closely and directly affected by my act that I ought reasonably have them in contemplation ...". Most cases will founder on your inability to foresee the use to which your software may be put. Consumer law is jurisdiction specific but they generally contain warranties that what you provide (gratis or otherwise) is fit for purpose, merchantable and that you do not make false and misleading statements. There is a chance that a case brought under this sort of law could succeed as you have not limited the purpose, specifically declared that it is not of merchantable quality and have (presumable) said what it does so that, if it doesn't do what you said, you have been misleading and deceptive.
Is there any state where someone doing this would potentially face manslaughter or murder charges, due to some variant of a 'life starts at conception' anti abortion law? Not really. Those laws are currently unconstitutional. A state could certainly prescribe some criminal punishment in a case like this one, but punishing under existing manslaughter or murder laws would almost surely not be upheld under existing law (subject to change without advanced notice by the U.S. Supreme Court). If someone knowingly and intentionally destroyed an embryo conceived via IVF but not implanted yet what kind of consequences do they face? Is the potential life treated differently or is this just destruction of property? This is a tough question that probably doesn't have a uniform answer under the law of all U.S. states. For one thing, it isn't clear who, if anyone, has property rights in the embryo. It is certainly conceivable that a state might instead conclude that the donor receiving the IVF treatment has only contract rights in it (and breach of a contract is not a crime). It might be viewed as a property destruction case. There might be a specific statute on point. There might be a civil lawsuit remedy. In most states, this would be an issue of first impression and a court would look a competing ways that cases had been handled in other jurisdictions to decide what to do in its case.
Typically in extraditions, the treaties will only allow for extraditions if both nations have a similar crime and similar punishment for that crime. In this case, there maybe some pause for Australia to grant an extradition as Australia no longer has the death penalty for any crime, so it could be that while the new crime the defendant is being sought for is Escape from Incarceration related (that's a yes in both countries), technically the punishment for an escaped Death Row Inmate is the Death Penalty. Australia can't extradite for any crime where death penalty is on the line, but the requesting nation can say they will give a more lighter sentance that is more compliant with the requested nation's own laws. However, since it is Death for another crime that Austrilia never had jurisdiction over, it complicates matters. There is precidence for procedural reasons for refusing to extradite. For example, while the U.S. and Italy have an extradition treaty and both view murder in the same light, the U.S. refused the extradition of a citizen who was wanted for a murder in Italy that she was previously aquitted of, but new evidnce was uncovered. Because it is illegal for the state to try a person twice for the same crime in the U.S., the U.S. declined the extradition treaty. Some additional notes, extradited persons can only be tried for crimes that they were extradited for, so there is an argument that Australia would refuse unless Indonesia promises to commute the Drug Trafficking sentence to Life Imprisonment
What would be an appropriate legal classification? A trust. How could this entity be structured so it could manage multiple estates? As a trust. Could this entity choose to keep, say, 30% for internal use e.g. resuscitation research? If that’s what it says in the trust deed, yes. How could this entity be made "recession-bulletproof," such that it could survive collapse of civilization? It can’t. Could it be given autonomy under the direction of a single person, or even sovereignty along the lines of a Mars colony? A trust is managed by its trustee(s) for the benefit of the beneficiaries. A trustee can be an individual or a corporation and there can be one or more of them. It couldn’t be given sovereignty - only nation states are sovereign. Could it be immune from legal jeopardy if it chose to accept clients who volunteer to be frozen before they die? No. What might happen to the estates if the economy is radically altered, e.g. a scarcity-free system where money is obsolete? Beats me - you’re the science fiction writer, you make it up.
Why do you think this is a hypothetical case? The facts almost exactly match R v Rogerson ; R v McNamara (No 57) [2016] NSWSC 1207 (2 September 2016) - 3 men enter a storage unit, 2 men and one dead body leave. Each of the men claims the other committed the murder - the DPP charged both, they were tried together, the jury convicted both and they both received life sentences. For the more general hypothetical: people can be tried together if that serves the interests of justice - defendants can apply to the court for separate trials but that is not always granted (and this may serve as grounds for an appeal ... or not). There is plenty of evidence of a murder, one (at least) of the two people is a murderer - prosecutors would charge both, present the evidence and let the jury decide which, if any, were guilty.
No Once a state has accused a person and tried that person for a particular act or set of acts, the state can't later hold a different trial for the same act or acts. That is the Double Jeopardy rule (or the basics of it at least). Some limited exceptions: If a person is convicted and appeals, and the conviction is overturned, the appellate court may order a new trial. *If there is a mistrial, such as a hung jury (jury cannot agree) then there can be a new trial. If an act is both a state and a Federal crime (in the US) then both can have separate trials, and possibly two convictions. If the accused bribes the judge or jury, that trial will not count, and there may be a new trial. If an act is a crime in two different countries, each can have its own trial (but often they don't). If it is later discovered that the accused committed a quite different act than the one s/he was tried for, a new trial for that act may be possible. But otherwise, whether the accused is acquitted or convicted, only one trial for a given alleged crime. The state cannot later change its mind on what to charge the accused with for the act.
