The process here was that government announced forfeiture action, people were given a chance to claim a property interest and fight the forfeiture, and no one chose to do so.
Ulbricht was clearly aware of it, and did assert a claim to other property that was the subject of the same forfeiture action. The seizure was a default judgement because there was no property owner to contest the forfeiture.
What additional process is due, and to whom is it due?
My guess is no one has stepped forward because it would make the party guilty. It'd be like an officer saying "Whose backpack is this?" and it has a bomb in it. The owner is in big trouble if they step up.
