PRIVILEGE - DO NOT FORWARD
Thanks Al.

Responding to your questions in red:

- We have always felt that even if [Horizon is susceptible to failures] was true it didn’t mean that the system
generated the losses complained of. Can we really demonstrate that?

The case we are running is not that Horizon is perfect and could never have caused a postmaster a loss. There
is too much data over too long a period to say that definitively.

Our case is that Horizon is robust, relative to comparable systems, and highly unlikely to have caused all of the
losses that all of the Claimants complain of. It is possible that on close examination of an individual case a
Horizon generated error may have caused a loss in branch. However the evidence from the experts, who are
supposed to be the main witnesses, is that that is highly unlikely.

- I wouldn’t disagree on some aspects of this — indeed a lot of our strategy is to rectify some of the cultural
underpinnings that still exist. So are we fighting all these points or accepting some but making the point
above?

My view is we are keeping our focus on the case we are running about Horizon’s overall robustness.
The “cultural” points have been put by the Claimants’ lawyers to our witnesses, so our lawyers haven’t had
much of an opportunity to fight them. The time for doing that if we wanted to, or for being contrite if that is
the better course, will be in written and oral closing arguments at the end of the trial.

Our lawyers have instead used the limited opportunity to mitigate “bad” evidence to clarify technical aspects
of our processes rather than fight perceptions of how we execute them.

On the evidence itself, Angela in particular readily accepted shortcomings in our conduct, e.g. where we had
not provided a good response to a postmaster’s call for help.

Ultimately, the evidence this week and last should be largely irrelevant given the trial should be about
technical issues decided on expert evidence. Based on the judge’s interventions and approach on the
Common Issues, we assume however that he will be influenced by it.

I hope that helps. Please let me know if you need anything further.

Thank you Rod. In the following para I think that you have exactly summed up what we are “losing” on.
POL00268881
POL00268881

The cross-examination was aimed at, and was largely successful at demonstrating:
a variety of incidents with Horizon, both in its software and the transaction records it generates, which:

© impact branch accounts;
© paint a picture of a system susceptible to failures, even if they are isolated and ultimately resolved; and

© are consistent with the errors experienced by the Claimants.
Post Office’s reliance on Horizon is overstated and blinkered, leading to an improper presumption of

postmaster fault and liability for branch losses.
Post Office has access to far better information from Horizon about branch accounting issues, which it is

better placed to use but does not share with, or actively withholds from, postmasters.
Post Office has overstated the improvements made to Horizon over the years, which it has been slow to roll

out and implemented purely to save costs.

And which I would expect to continue to lose on.

My questions are
We have always felt that even if the above was true it didn’t mean that the system generated the

losses complained of. Can we really demonstrate that?
I wouldn’t disagree on some aspects of this — indeed a lot of our strategy is to rectify some of the

cultural underpinnings that still exist. So are we fighting all these points or accepting some but

Post Office Group Litigation - SUBJECT TO LEGAL PRIVILEGE - DO NOT FORWARD

All,

On Monday and Tuesday the Claimants’ counsel team cross-examined Angela van den Bogerd, Dawn Phillips, Tracy
Mather and Paul Smith from Post Office, with Angela’s cross-examination by the Claimants’ QC Patrick Green
occupying just over a day and a half of the two days.

The cross-examination was aimed at, and was largely successful at demonstrating:
-  avariety of incidents with Horizon, both in its software and the transaction records it generates, which:
o impact branch accounts;
© paint a picture of a system susceptible to failures, even if they are isolated and ultimately resolved; and
© are consistent with the errors experienced by the Claimants.
- Post Office’s reliance on Horizon is overstated and blinkered, leading to an improper presumption of
postmaster fault and liability for branch losses.
- Post Office has access to far better information from Horizon about branch accounting issues, which it is
better placed to use but does not share with, or actively withholds from, postmasters.
- Post Office has overstated the improvements made to Horizon over the years, which it has been slow to roll
out and implemented purely to save costs.

Through the cross-examination, the Judge has challenged on a number of occasions the content of the Post Office
witnesses’ statements (e.g. where the witness has provided information collated with the assistance of other Post
Office personnel, or has corrected or clarified the evidence). He has also taken issue with Post Office’s document
disclosure, in particular where redactions have been made. When considered in the context of the Common Issues
Judgment, these challenges suggest he could be equally critical of Post Office’s evidence when giving judgment on the
Horizon Issues.

The Claimants will today cross-examine the final Post Office employee, Dave Johnson, before starting their cross-
examination of the four witnesses Post Office has called from Fujitsu. The Claimants are required to complete their

cross—examination by the end of Thursday.

Kind regards, Rod
