Re: "The finding is a massive victory for HPE"
The problem with Due Dilligence in this case is that it was relying on a tainted source. The fraud was deeper, in the business practices. So even if HP had read the documents, it may well have not made that much difference. After all, Deloitte were deceived / allowed themselves to be deceived, and they (should have) had a closer handle on the Autonomy business than would be in the due dilligence documents alone.
We 'll see what the Judge thinks when he announces the amount of damages. I'm guessing he will give some discount for HP's carelessness, but maybe not that much. But even if he discounts by say only 10%, that is a larger sum of money than I can imagine, lost for lack of reading the paperwork.
