Normally stolen goods are illegal in consequence, if not returned to their rightful owners; so an expert opinion from a qualified lawyer would be a good thing indeed.
Coins are not goods, and they were returned to our community, so they are not stolen at the moment.
Of course, now when they are returned, only their rightful owners can decide what to do with them, otherwise, they really will be stolen.
But another thing is that coins in fact were blocked/frozen, so it's like they are out of supply and are 'unofficial coins' now.
Remember that investors were investing because they believed these coins were frozen, maybe the price of Mooncoin never went to these levels without that,
so to 'unfreeze' them means that the decision-makers of this could be held liable for the loss of these investors afterwards.
So these coins are not Mooncoins, they are 'unofficial, frozen Mooncoins' which should be burnt, just to stay out of supply forever.
