There is a slight relevance of Bitcoin: Bitcoin transactions are irreversible. There is no real technical means to reverse a transaction; it is simply not possible. Even if there was a court order to reverse a transaction, unless the physical recipient could be identified, located, and arrested, the court order would be meaningless.

This is in contrast to almost any other exchange system (besides hard cash), which could, at least technically, force reversal of a transaction. See for example Paypal, Facebook credits, money in an MMORPG, shares of stock, and so forth.
