Here off course it depends on the laws of that country. For instance Philippines could certainly have said its your mistake so you owe people money instead. They would have then taken higher steps than that if the company failed to pay back like canceling passports of foreign employees and extradition of executives.
Off course this is all hypothetical but there should be laws that hold companies responsible for their own mistakes.
And, actually, if someone accidentally deposits 1m into your bank account, you do owe them shit. Specifically, you owe them 1m.
What you're saying is just so ridiculous I'm having a hard time taking you seriously.
If you are ordered to pay money by the government and can't pay it may considered fraud. So the government can take bigger actions. I guess bankruptcy may follow where the government can end up seizing all assets the company has. If all those steps are insufficient then even bigger steps may follow.
As I said it all depends on the laws of that country. Not all countries have similar laws.
