I'm perfectly happy to have a serious debate about this. But before I do so you really do need to do some proper research. Until then, I think we're back to "ask your dad".
Stop playing hide&seek games and cite some case law.
I've already provided a resource which says
nemo dat quod non habet applies in tracing into mixed funds.
Now it is your turn to cite something that refutes that. Otherwise you are just playing games.
DooMAD and crazy_rabbit, I'm happy if you convince yourselves to make the biggest mistake of life. Please proceed.
nemo dat quod non habet has been fundamental to Western civilization. You proceed in your Alice in Wonderland fantasy.
Besides the USA has succeeded in forcing every
major country to acquiese to our FATCA law, which is much more intrusive into sovereignty than
nemo dat quod non habet norms in western civilization.
DooMAD apparently you are in the UK and
nemo dat quod non habet originates from your country.
I think you guys have a few screws loose.
