I think the govt would have to use the same means it would use to prove that you know the whereabouts of a missing person.
They can't hold you forever (except maybe in enemy combatant like scenarios), much like if you picked up a girl from a club at midnight, and no one ever saw her again. Your claim is you dropped her off at her apartment at 3am, but there's no evidence of it. They can ask you what they want, but w/o more evidence they can't just lock you up forever.
But with more evidence, for example, if they find IMs where you mention that you've hidden something in hidden volumes, they may have more options open to them.
I guess my point is that this seems to fall into standard practice, more than this being a one off rule specific to hidden volumes.
Yea. Your point is that they can't lock you up forever based on the suspicion of a hidden volume. My point is that it would likely to be hard to them to reasonably assert a hidden volume, and even if they could assert a hidden volume, if you unlocked one but had several, they wouldn't be able to reasonably convince a judge of suspicion of several hidden volumes.
Then, having several is difficult since they all have to nest, and can't reside in parallel (i.e. the second hidden volume has to be inside the first hidden volume, it can't reside along side the first hidden volume within the top-level volume).
