The way Mt. Gox is holding customer deposits, is it allowed in Japan. Cant there be any lawsuit ? (I'm sorry I dunno if there's already one !!!)
Mt. Gox can be sued in the US, in Delaware, where they have a legal presence for FinCen purposes. They can be sued in Japan. The Japan Financial Services Agency has the authority to regulate them. Yet there are no published reports of anything happening.
I suspect that there have been legal actions, and that anyone who files suit is paid off immediately if they sign a nondisclosure agreement.
