Attachments: Horizon Version 2.doc
Alice and Paula — attached is a redraft of the TOR, hopefully this picks up the issues raised this morning.
In addition, and following a review of the cases listed, which I had not seen this before, I have been giving some further
thought to our position particularly in respect of the cases where we have criminally prosecuted the sub
postmaster/mistress. In those cases I do not think that we want to be seen as re-opening the cases but rather position
this as a review of the existing evidence to enable an understanding of the outstanding concerns and the facts in so far as
they concern the Horizon system. For those who have not been prosecuted we can offer a full independent
investigation.
@ The overall outcome would be a general conclusion which critically reviews the evidence already in existence and new
evidence from the work done by the independent forensic auditor.
If you agree with the above then the TOR would need to be slightly amended to take this into account.

For those that haven't been prosecuted we can position as a full independent investigation.
The overall report should then be a general conclusion looking at a mixture evidence already in existence (from previous
cases) and new evidence gained from their own investigation to determine whether there are any systemic Horizon
problems.
