Asset forfeiture against property is part of civil law and as such is still subject to the concept of a fair trial, even if in practice it often is not. The bar for conviction is lower but the process is still supposed to be considering what is fair. Just because it is civil law does not exempt it from that basic legal principle.
It's a lot less fair when your assets are seized (in general, not just the SR case). In fact, wasn't that part of the whole reason people accept seizure laws?
Also, he is getting a fair trial.
