Sears: "I am attending under duress as part of my bail conditions. I am remaining silent, as is my right."
On sears advice, it might not be that bad and it would be consistent with your reasoning for appealing your existing sentence order. It strikes me that you need to make a decision on how to play this: whether to go through the motions and comply; or whether to refuse to speak on the grounds that you are being forced to attend against your will, due to a flawed/unreasonable sentence order, which you are in the process of appealing against.
