I am completely mystified.
I expected HM to appeal anything more than the 'assisting' charge that carried a 9-month penalty. I can't believe she's just going to accept her ten year sentence (minus any time off for 'good behavior').
No way with what's going on regarding corruption in their courts right now would AS advise her to appeal at this point. I think the writing was on the wall for HM that she was likely going to get the 15 years that the prosecution asked for, much better than life or a death sentence. She had started to make preparations to get money via Stella so I think she knew she was going to be in there for a while. 10 years is actually less than she probably thought she'd get...hence the celebrating and smiles after the verdict.
I think she completely snowed TS to get him to lie about her participation and told him she was paying a bribe for both of them to get the same sentence. He probably thought they'd get the same and was not impressed at all with the outcome.
But to appeal? With possibly no money to bribe the judges with again? That would be crazy. The next panel might actually read the evidence and say WTF? on the first verdict.

MOO
