A plane goes trough some kind of atmospheric disturbance and ends up badly damaged, crashing after trying an emergency landing. Of 200 passengers onboard, only 80 survive, some of them badly injured (comatose, paralytic, crippled, etc). One year later, the exact same plane with the same 200 people appears out of nowhere and this time lands without any problem.
Basically, the question is: Will law consider the people of the second plane as the same person, as an impersonator or just as a new person? i.e.:
- Would insurance companies be able to reclaim the payments they made, as their customers are alive and well?
- If one of the dead passengers was a criminal going to trial, would the case be reopened?
- Would a "reappeared" person be able to recover his money from the heirs?
- Could survivors be legally forced to divide their money and properties with the "duplicates"?
- Could a passenger disconnect the vital support of his comatose counterpart?
After reading the comments I have to agree with the general consensus that the question is too broad and open to answers more based on opinions that on actual "imaginative" interpretations of existing laws, even more difficult without knowing the legal system. As for that, I was afraid that setting the events in a given place would limit the answers or make it too much specific: While no modern democratic country has laws that take into account an anomaly in the space-time continuum, some may be more suitable than others (for this particular case) and that could give a hint on how a similar legal system would react.
Also, I've got several interesting and reasonable answers and now I see that it would be kind of difficult and arbitrary to accept one over the others, so I probably have to give it more time to articulate a better question. Thanks for all your help.
