Of course it depends on jurisdiction, but it would be really interesting to see what would happen if someone got their hands on keys of some commercial organizations’ wallet and then publicly announced (according to the premise that they are the rightful owner). E.g by using a PRNG-weakness in some HSM or something, i.e no entry into their networks etc.
My guess is that the court would recognize the first owner as the “real” owner, especially if they can show that they controlled the address up until some point.
In a similar vain condictio indebiti is a principle in maybe jurisdictions, where a receiver of a wrongful payment is required to return it. Even if the payment is made with crypto, the principle would probably stand if it’s practical to enforce.
