Further update from Robert.
Coyne is still being a pain
RW asked him straight up whether he thought Horizon was robust, and Coyne refused to answer the question!

Coyne is focusing on there being little evidence of PO remediating branches after a bug. RW's response (entirely
unprompted by me) is that this is missing the point and he intends to put the following in the joint memo:

e Whether the SPM is remediated has a bearing on whether the branch accounts are accurate but has
no bearing on the reliability of Horizon.
e — Horizon is reliable if the bugs are fixed so that they don't reoccur.
POL00364016
POL00364016

e One would not expect to see evidence of remediation in the Peaks and KELs because that was not
their purpose so Coyne's point about a lack of evidence misunderstands the evidence he has.

This very neatly aligns with what Parker 3 will say.

He’s not an idiot, he’s biased.

Found it. The answer is that the document that Coyne cites at Coyne 2/5.404(c) does not say what he says it does. It is
fairly clear! The amount settled centrally WILL be treated as a debt UNLESS it is disputed.

I do agree — although as RW made Simon’s points forcefully to JC in an email a few days ago, I doubt much needs to be
POL00364016
POL00364016

said — it’s more a matter of gently reminding him about what he knows already. I strongly suspect that RW will end up
there anyway. I don't think there is anything more we can or should do. I am at least pleased that RW is determined to
produce something in a form, which is useful to the court. The other side’s mucking about with his inputs when they
have control, is remarkable and troubling, but this is all WP and each expert can do what he wants. The only sanction is
if it becomes apparent that one expert is trying to help the court and the other is not. We’ve no idea if the final document
will demonstrate that we are in this territory.

On RW setting out what he thinks about the 22 bugs in a table, can I repeat a point I made the other day — have
we checked that what he thinks (he gave us a table a week ago) says anything radically inconsistent with what we
now think about the 22 bugs and, if so, is there anything we can do about that, without giving RW material that is
not available to Coyne?

On a careful reading of the reports, there should be much more for the experts to agree about than a superficial reading
suggests. Virtually all the miscellaneous operational/functional issues should be agreed (2 — Horizon alerting SPMs to
bugs; 3 — how does Horizon compare its data to outside data; 8 and 9 — reporting functions available to Post
Office/Fujitsu and SPMs; 14 — functionality in balancing and accepting/disputing shortfalls; and 15 — TCs).

Incidentally, one possible exception is issue 14c(ii), where JC has pointed out that our stated position in the common
issues trial was that a disputed shortfall that was settled centrally was recorded as a debt due to Post Office. I keep
meaning to ask - has RW asked for any help on the point? Do you have any thoughts that might help, Owain?

I don't think it is unhelpful for the experts to delay addressing remote access, since we may be serving useful evidence on
the point in the early part of next week (he said, hopefully). I approved of the proposal to have staged joint statements,
one dealing with robustness/the 22 bugs and some low hanging fruit, and the other dealing with remote access etc. But
there is no more time to play with and we obviously want everything signed off by next Friday at the absolute latest.

Andy

I think it would be legitimate to remind Robert that this is a statement of matters agreed and not agreed and while as
a general principle agreement is better than disagreement, he is perfectly entitled to record his position of
disagreement in a standalone way as long as it is made clear that such sections are his views alone. In other words, he
can if he wants go through e.g. the 22 issues and saying what he accepts and rejects in relation to each issue. That is
perhaps a less useful way of presenting things for the Court — since the extent of agreement and disagreement may
not be as apparent as it would be for example if there were to be a single table, but it is a great deal more useful than
producing nothing.

Tony — do you agree?

Best
Simon

See below. Looks like the joint memo is not going well.

I'm not sure that there is a lot that we can do?

Andy -
Producing JM2 is proving very difficult.

Jason and Siobhan made a total mess of it while they were editing it into their template, and conveniently lost a large
proportion of my inputs.

Yesterday Chris did a heroic job of restoring it to a decent state, and restoring all my inputs.

However, I strongly suspect that Jason is creating confusion and delay in order to stop it being a useful document for
the court. Siobhan is competent and could have produced a decent document if she had wanted to.

He and Siobhan have the baton today on the master version, and might try to make a mess of it again. (if necessary I
will go back to a clean version and put in their rows and mods to agreements which I can accept)

We agreed during the meeting that getting JM2 out today was not possible, and that we would probably slip until
Monday.

Jason is at a wedding most of the weekend, and Chris is tied up for most of it. Fortunately I have most of the weekend
available to sort it out if necessary.

It appears that JM2 is going to cover the bugs table and selected issues - certainly 1, certainly not 3, certainly not
remote access 10, probably 9, 14 and 15.

A schedule of Wednesday for JM3 is therefore looking very challenging.
Any advice gratefully received!
Robert
