As for the AA workers, they may need to move, but the work they used to do will still have to be done by someone. The rise of fall of companies is characteristic of our system.
What do you think about making all AA partners disbursement over the time period liable for the effects of non-standard and negligent (or corrupt) figures in one of their member's audit? If not in this case, in the future? After all, if an AA partner is given credibility from his LLP association, shouldn't he should share in that liability (up to the amount of his income?)
