POST OFFICE HORIZON IT INQUIRY

FIRST WITNESS STATEMENT OF Ian Rutherford HENDERSON

I, lan Rutherford HENDERSON, will say as follows...

BACKGROUND

1. lam currently a director of both Second Sight Investigations Ltd and Second
Sight Support Services Ltd. In 2012 I was engaged as a consultant /

contractor to Second Sight Support Services Ltd.

2. I hold the following professional qualifications:
a) Fellow of the Institute of Chartered Accountants in England and Wales;

b) ISACA Certified Information Systems Auditor.

3. In 2012 I was also a member of International Society of Forensic Computer
Examiners (“ISFCE”) and an ISFCE Certified Computer Examiner. I no longer

hold that qualification.

I have a long history of investigations and regulatory work. Prior to moving
into the private sector in 1998, I was Head of Investigations at the UK’s
largest Financial Services Regulator. Immediately before this, I was Manager
of the Investigations Department of Lloyd's of London with responsibility for

investigating fraud and misconduct world-wide.

Before starting training to become a Chartered Accountant in 1980, I served
nine years in the British Army in a wide variety of roles. Between 2001 and
2005 I was appointed on a part-time basis, as a special adviser to the
Criminal Cases Review Commission. This provided me with an extensive

insight into issues relevant to criminal appeals.

I regularly provide evidence as an expert witness in cases involving suspected
fraud, digital evidence and the disclosure of electronic documents. I was also
selected as a contributing author to the Association of Certified Fraud

Examiners “Fraud Casebook’.

7. Cases where I have been instructed as an Expert Witness include:

a) Rv Lee Williamson (Northern Ireland Court of Appeal)

b) Rebecca Vardy v Coleen Rooney (RCJ — Queen’s Bench Division)
c) Dr Craig Wright v Marcus Granath (RCJ — Queen’s Bench Division)
d) Rv Roger Allen (Court of Appeal - Criminal Division)

e) Rv Wendy Cousins (Court of Appeal - Criminal Division)

f) Kv K (Central Family Court)

Republic of South Africa v Jacob Zuma and Thint - instructed jointly

eg

with Peter Sommer Esq.

h) Sienna Miller v News Group Newspapers and Others (RCJ — Chancery
Division)

i) Kelly Hoppen v News International and Others (RCJ — Chancery

0) Martha Greene v Associated Newspapers and Peter Wright (Court of
Appeal - Civil Division)

p) GE Commercial Finance v Messrs. Gee and Others (RCJ — Queen's
Bench Division)

q) Rv Mustapha Taleb and Others (Central Criminal Court)

8. Lee Williamson, Roger Allen and Wendy Cousins (above) are all Post Office

Horizon appeal cases.

9. I would also add that I come from a post office family. My parents ran a rural
post office for many years and I fondly remember earning pocket money
during school holidays by delivering urgent telegrams using a “sit up and beg”

Post Office bicycle. This of course was long before computerisation and Post

Page 3 of 63
WITNO0420100
WITNO0420100

Office Horizon, but it gave me an in-depth understanding of the relationship

between a rural post office and the local community.

10.1 would also mention that I have a formal diagnosis of high functioning autism
(autism spectrum disorder). This probably explains my somewhat obsessive
interest in data and documents and my relatively poor social communication

skills. I am also a member of MENSA.

11.This witness statement is made to assist the Post Office Horizon IT Inquiry
(the “Inquiry”) with the matters set out in the Rule 9 Request dated 3 April

2024 (the “Request”)

REQUEST FOR INFORMATION

12.On 3 April 2024 the Post Office Horizon IT Inquiry wrote to my then
Recognised Legal Representative (Hudgell Solicitors) with a “Request for

information pursuant to Rule 9 of the Inquiry Rules 2006”.

13.1 was requested to:

... set out how you first became instructed in relation to the issues being
investigated by the Inquiry including, but not limited to, relevant dates and the
names of individuals who instructed you, how and why you were approached,

and any initial briefing or information that was provided to you.

Page 4 of 63
WITNO0420100
WITNO0420100

14. Detailed guidance was provided together with copies of 64 “relevant

documents” that I was asked to consider.

15.1 have been asked to provide a detailed chronological account of my
involvement in matters relating to Post Office Ltd (“POL”) and the issues being
investigated by the Inquiry and to set out in detail, with reference to relevant
documents, my involvement in (at least) the following (“Relevant Events”):

a) The Second Sight Inquiry [POL0000021 8].

b) Interim Report of 8 July 2013 [POL00099063].

c) Complaint Review and Mediation Scheme of 2014 [POL00000213],
[POL00043353].

d) Part 1 Report of 25 July 2014 [POL00004439].

e) Part 2 Report of 21 August 2014 [POL00030160].

f) Part 2 Report of 9 April 2015 [POL00029849].

16.On 18 April 2024, I was notified that Hudgell’s had identified a conflict of
interest and were unable to continue acting as my Recognised Legal
Representative. In view of the imminent deadline for my witness statement set
by the enquiry (Initially 1 May 2024 but then extended to 8 May 2024) I felt
that I had no choice other than to continue without the assistance of a

Recognised Legal Representative. I notified the Inquiry accordingly.

WITNO0420100
WITNO0420100

LIMITATION OF SCOPE

17.As I explain further below, in 2015 I was instructed by POL to destroy all of
the documents relating to my previous work for POL. This was after delivering
to POL the original or master copies of those documents. I was permitted to
retain a list of the approximately 34,000 documents returned to POL. I have
provided a copy of this list of documents to both the Inquiry and to the

Metropolitan Police [POL00065985].

18.1 do not know whether my original 34,000 documents have been made
available to the Inquiry. I do recall that POL contacted me sometime in 2015
or 2016 because they had lost the password needed to access these
documents. I provided the password to POL again, but I subsequently
became aware that POL had not maintained the directory or folder structure of

documents, which meant that the documents were very difficult to access.

19. This witness statement has been prepared without being able to review the
documents deleted in 2015 and is based primarily on my recollection of the

work performed for POL between 2012 and 2015.

20.1 have found preparing this witness statement to be quite difficult as so few
documents have been made available to me, just 64 documents out of the
over 34,000 documents previously held by me. The Inquiry has not provided

me with access to the Relativity database which may hold some of these

Page 6 of 63
WITNO0420100
WITNO0420100

documents. (Nor have I requested access due to the time constraints on

preparing this witness statement.)

21.My normal practice in a witness statement is to ensure that every element of
my statement is supported by documentary or other evidence. I would
normally prepare an audit file cross-referencing each element of my statement

to a source document. I have not been able to do that in this case.

MY INVOLVEMENT IN THE RELEVANT EVENTS

The Second Sight Inquiry

22.The Second Sight Inquiry started in about July 2012. Ron Warmington
submitted a business proposal to POL dated 1st June 2012 [POL00096576].
A document [POL00096575] prepared by Susan Crichton (POL Head of
Legal) described the objectives as:
a) Carefully review all company-held documentation focussing heavily on
probable reasons why shortfalls occurred or built up;
b) Interview company investigators to gain insights and to verify fairness of
findings;
c) Review defence submissions focussing on evidence of innocence
(consider separately False Accounting and Theft);
d) Try to establish why the shortages arose (assign each case toa

Probability Category such as: Skill shortfall; Diversion to Failing

Business; Straightforward Theft (by whom?); Mysterious Disappearance;
etc.)

e) Review all materials from the viewpoint of the Defence (seek Proof of
Innocence and test evidence indicative of guilt);

f) Study and selectively test, the 'Horizon ' system in order to find any
‘Black Hole’, Program Bug; etc. that might have caused mysterious
shortages;

g) Reach conclusions on each case and identify any systemic

issues/concerns.

Our appointment was not straightforward. Alan Bates and the Justice for Sub-
postmasters Alliance (“JFSA”) were concerned that we would not be truly
independent and would say whatever Post Office wanted us to say. Post
Office needed to be assured that we had the necessary skills for the task.

MPs did not want to support something that wasn’t going to work.

Ron Warmington and I attended a selection interview at Portcullis House on
12 July 2012. I recall that we spent some time discussing the appropriate
approach to this matter. Rather than attempt a code review of the Horizon
software, I said that my approach would be to treat Horizon as a “sealed black
box” and look at inputs and outputs, rather than try and work out exactly what
the software was doing. We did briefly discuss the feasibility of a code review,

but the cost of this was likely to be prohibitive and of limited benefit.

Page 8 of 63
WITNO0420100
WITNO0420100

25.\t was unclear at this stage how many cases would be submitted for review.
Some cases came directly from MPs and others from the Alan Bates and the

Justice for Sub-postmasters Alliance (“JFSA”).

26.Ron Warmington and I discussed our approach to this work and in general
terms we agreed that I would focus on the data and documents held by POL
together with the technical evidence and Ron would lead on the interviews of

sub-postmasters.

27.Our appointment was unusual. We were appointed by a small group of
Members of Parliament at the request of the Justice for Subpostmasters
Alliance (‘JFSA’) but with the support of POL. Our professional fees were paid
directly by POL. JFSA had been pressing for some form of independent
inquiry for many years and had gained the support of influential MPs
representing constituents who had suffered mysterious shortfalls in branch

accounts.

28.1 regarded that our terms of appointment were quite clear. They included:
a) unrestricted access to documents held by Post Office (including
documents subject to confidentiality and legal professional privilege);
b) no limitation in the scope of work determined necessary by Second

Sight.

Page 9 of 63
WITNO0420100
WITNO0420100

29.In the course of our work, over more than 3 years, we investigated
approximately 140 individual cases. We reviewed the sub-postmasters’ own
assertions; the cases put forward on their behalf by their professional advisors
together with Post Office’s reports prepared in response. We examined
thousands of documents and established which were significant. We created
a structured, evidential database of over 34,000 individual documents. We
identified 19 thematic issues that were common features to many of the cases
under examination. We were then able to cross-reference each case to others

having similar characteristics.

30. Our work started in the summer of 2012. My main contacts at POL in 2012
were Simon Baker and Susan Crichton. Initially, POL were co-operative and

appeared committed to the agreed goal:

“to seek the truth, irrespective of the consequences”.

31.1 can’t remember when we first used this phrase, but it reflected a concern
first raised by Ron Warmington quite early on in our work, that we may
uncover facts that would either embarrass POL or may have serious financial

consequences. POL confirmed to us that they accepted this risk.

32.To start with I spent a few days working in the legal department of POL

headquarters London. I had a desk in the open-plan office used by the legal

department and sat just outside the office used by Susan Crichton, the then

Page 10 of 63
WITNO0420100
WITNO0420100

Head of Legal for POL. My main day-to-day contact was Jarnail Singh, who

was the POL senior prosecution lawyer.

33.1 started by asking to see all of the POL files relating to criminal prosecutions.
Only about 10 case files were provided initially. This surprised me, as I was
aware that they were potentially hundreds of prosecutions. I was told that the
reason for only 10 files being held by the legal department was:

a) a7-year file destruction policy; and
b) prosecutions generally, were outsourced to legal firms all over the UK

and case files were not held centrally.

34. Within a few days of our appointment, we asked for 3 actions to be taken:

a) issue a POL wide “litigation hold” that would prevent any further relevant
documents being destroyed;

b) collate all of the then available prosecution files, including those held by
third-party law firms, in one place; and

c) send all of the prosecution files then held by POL, to a third-party
scanning bureau. This ensured that these vital documents would be
preserved and made more readily available. This comprised

approximately 4,000 documents and was known as CD1.

35.In July 2012 the office of the Rt. Hon. James Arbuthnot MP was co-ordinating

possible cases from other MPs. [POL00096834]

Page 11 of 63
WITNO0420100
WITNO0420100

36.1 was surprised at the small size of the legal department within POL,
approximately 10 members of staff. I also noticed the difficulties the
department had in getting case files under control. I discussed this in general
terms with Susan Crichton and formed the view that this is what POL inherited
following the split from Royal Mail Group in 2012 and that there had never
been a proper assessment of what was really needed to function effectively.
Susan Crichton told me that she had no background in criminal law and relied

on Jarnail Singh in terms of criminal procedure and administration.

37.The main focus within the Legal Department was paper based files rather
than electronic files. It had the air of a rather old-fashioned department with
secretaries or personal assistants typing letters or memoranda, which were

then placed on the file.

38.One of the case files made available to me quite early on, was the
prosecution of Jo Hamilton. I read this file quite carefully before it was sent to
the bureau for scanning and was surprised to see a POL Security Report

[POL00044389] that stated:

“Having analysed the Horizon printouts and accounting documentation I
was unable to find any evidence of theft or that the cash figures had been

deliberately inflated.”

39.1 could also see that Jo Hamilton had been charged with theft and false
accounting which did not seem to be supported by the internal POL Security

Page 12 of 63
WITNO0420100
WITNO0420100

report. I raised this apparent inconsistency with Susan Crichton and was told
to speak to Jarnail Singh, which I did. Jarnail, told me that everything that
needed to be disclosed had been disclosed and that there was nothing to

worry about.

40. Notwithstanding this assurance from an experienced POL criminal lawyer, I
was left feeling uncomfortable and felt it was even more important to make
sure that all of the relevant files were sent to the scanning bureau and made

accessible for the purposes of our investigation.

41.1 spent some time researching the legal position whilst I was working in the
POL legal department. From memory, I established that Royal Mail Group
(‘“RMG”) was a prosecuting authority in its own right, but that following the split
from RMG, POL was conducting private prosecutions. I was not aware of any
POL prosecution that had been referred to, or taken over by the Crown
Prosecution Service, which is always an option when conducting a private

prosecution.

42. It took some time for POL to gather all of the available prosecution files that
we had requested. From memory, the CD containing the scanned files was

made available to us towards the end of October 2012.

43.In September 2012 I met with Gareth Jenkins, the lead engineer for Post

Office Horizon, at the head office of Fujitsu in Bracknell. He told me that

Page 13 of 63
WITNO0420100
WITNO0420100

approximately 10 members of staff from Post Office were permanently based

in Bracknell, dealing with various issues including bugs, errors and defects.

44. Gareth Jenkins told me that Fujitsu routinely used remote access to branch
terminals for various purposes. This was often without the knowledge or
specific consent of individual sub-postmasters. He also told me that members
of his team could connect remotely to branch terminals and generate
keystrokes that were indistinguishable from a sub-postmaster accessing the
terminal directly. They did this for various purposes, including collecting log

files directly from branch terminals.

45.In my opinion, this facility (if confirmed) had major implications for the safety
of criminal convictions, as it meant that the sub-postmaster was no longer in

sole charge of data entries being input on his terminal.

46.1 subsequently shared this information with Alwen Lyons (POL Company
Secretary) and Lesley Sewell (POL Head of Information Technology) and was
told quite firmly, that I was mistaken and that POL had received assurances
about this in various audit reports. This point was made very firmly to me, and
I recall telling Ron Warmington shortly afterwards, that I felt that if I made an

issue of it there was a significant risk of Second Sight being sacked.

47.\ also discussed the issue of POL employees working at Bracknell with Simon

Baker. He told me that he had researched the issue and was surprised to find

Page 14 of 63
WITNO0420100
WITNO0420100

that he in fact, was their line manager, something that he had previously been

unaware.

48. It was at about this point, that I decided the best way to resolve the issue was
to request the full email archives for the POL employees at Bracknell, as this

would shed light on what they are actually doing.

49. In the light of this unexpected response by POL, I decided to treat this issue
as a potential conflict of evidence and to continue to gather evidence in order
to investigate the relevant issues and ultimately to form an evidence-based

view on this matter.

50. Shortly after my meeting with Fujitsu, Gareth Jenkins provided me with some
sample data from the Horizon system. I subsequently established that POL
routinely relied on various reports from Fujitsu including the so-called ARQ
reports — (“Audit Request Query”). However, I established that a more
detailed report was in fact available. This was called the XML report
(“Extensible Markup Language”), that provided a greater degree of detail, than

the ARQ reports typically provided by Fujitsu to POL.

51. There were however financial consequences of requesting these more
detailed XML reports, or even excessive numbers of ARQ reports. POL was

entitled to a small number of ARQ reports free of charge each month. I

Page 15 of 63
WITNO0420100
WITNO0420100

subsequently became aware that POL was not supplying reports to sub-

postmasters in some cases, due to the extra cost of doing so.

52.An examination of a small number of XML reports provided to me,
established, as some sub-postmasters had suspected, there were in fact out
of hours transactions being generated by the Horizon system and not directly

input by sub-postmasters at branch terminals.

53.Within days of being provided with CD1 in late October 2012, we realised that
we may be looking at a significant number of miscarriages of justice. There
was a lack of effective investigation, multiple disclosure failures and conduct
by prosecutors that needed to be considered by experts in criminal law and

prosecutions.

54. Rather than just rely on the relatively small number of potential cases notified
to MPs we agreed with POL that a letter would be sent to all known sub-
postmasters and former sub-postmasters inviting them to submit cases direct
to Second Sight. This letter titled “Raising Concerns with Horizon” was sent
out in late December 2012 [POL00000218]. It requested responses to be sent

to either JFSA or direct to Second Sight by 28 February 2013.

Page 16 of 63
WITNO0420100
WITNO0420100

55. The remit of the Inquiry [POL00000218] was described as:

“The remit of the Inquiry will be to consider and to advise on whether
there are any systemic issues and/or concerns with the "Horizon"
system, including training and support processes, giving evidence and
reasons for the conclusions reached.

The Inquiry is not asked to investigate or comment on general
improvements which might be made to Horizon, or on any individual
concern raised (see below) save to the extent that it concludes that
such investigation or comment is necessary to address the remit.

The Inquiry is not a mediation or arbitration. It is not intended to resolve
or affect any dispute there may be between any individual Horizon user

and Post Office Limited.”

56.We then started to receive individual notifications either direct from sub-

postmasters or via the JFSA. These responses were then analysed and
“thematic issues” identified. This approach had the advantage of creating a
limited number of discrete issues to be investigated. The agreed thematic
issues were eventually established as follows:

a) Transactions or Transaction Corrections not entered by the Sub-

postmaster or staff;

b) Transaction anomalies associated with CASH or STOCK Remittances;

c) Transaction anomalies associated with Pensions and Allowances;

d) Transaction anomalies following telecommunication or power failures;

e) Transaction anomalies associated with ATMs;

Page 17 of 63
WITNO0420100
WITNO0420100

f) Transaction anomalies associated with Lottery Terminal or Scratch
Cards;

g) Transaction anomalies associated with MVL;

h) Transaction anomalies associated with Foreign Currency;

i) Transaction anomalies associated with Bank / GIRO / Cheques;

j) Transaction anomalies associated with Stamps, Postage Labels, Phone
Cards or Premium Bonds;

k) Hardware issues e.g. printer problems, PIN pads, touch screens and
PayStation;

I) Failure to follow correct procedures or mis-advice by POL's HelpLine;

m) Training and Support issues including HelpLine and Audit;

n) Limitations in the Transaction Audit Trail available to Subpostmasters;

©) Process issues at the end of each Trading Period;

p) The contract between the Post Office and Subpostmasters;

q) The lack of an outreach investigations function;

r) Improper behaviour on branch closure; and

s) Abuse of Criminal Prosecution Process.

57.Ron Warmington and I continued to investigate the 49 submissions received
by 28 February 2013. It was at this point that we developed the concept of
“spot reviews”. A “spot review” was defined as:
‘a narrowly focussed review looking at a specific issue over a limited
time scale that is potentially capable of corroboration by 3rd party
evidence and also where full Horizon data for the incident remains

available”

Page 18 of 63
WITNO0420100
WITNO0420100

58. This had the advantage of being quicker and more focused than an in-depth

investigation into every case submitted.

59. Document [POL001847 16] highlights a key issue that was central throughout

our work for POL. This was the question as to whether or not POL (or Fujitsu)
could alter or inject transactions without the knowledge or approval of sub-
postmasters. My developing view on this was that as a result of my meeting
with Gareth Jenkins, it was in fact possible to inject transactions without the
knowledge or approval of sub- postmasters, but this was a position not

accepted by POL.

60. Document [POL000975839] is an internal briefing note prepared by POL that I

61.

have not previously seen. It accurately describes the recently agreed concept

of “spot reviews.”

Document [POL00105631] is described as “Agenda for meeting re Post
Office cases” but appears to be a file note / summary of the meeting with MPs
that took place on 25 March 2013. It was probably prepared by the personal
assistant to James Arbuthnot. It confirms that 49 cases are under active
investigation but that the investigations were still at the evidence gathering
stage and that POL had not yet submitted their assessment of any of the

cases being reviewed.

Page 19 of 63
WITNO0420100
WITNO0420100

62. Document [POL00097864] is an email from James Arbuthnot to Susan
Crichton raising concerns about my file note of the meeting with MPs on 25
March 2013. James Arbuthnot is a very experienced parliamentarian and I
was happy to accept his comments on my file note. I would probably describe
the differences as being points of emphasis, rather than substance. Document

[POL00097883], not previously seen, is a POL commentary on this issue.

63. Document [POL00090358] is a 327-page document that appears to be a
scanned copy of a POL hardcopy file titled: “Complaint Review and Mediation
Scheme (Chronology and Supporting Documents) File 2 of 5 from April 2013
to October 2015”. I note that this is only 1 file out of a set of 5 files. I do not

know if the remaining 4 files have been made available to the Inquiry.

64. Document [POL00090358] includes many documents not previously seen by
me, but also many documents that are difficult to read due to the scanning

process.

65. Document [POL00122393] is a POL generated document dated April 2013,
not previously seen by me. It is a discussion document that explores various
options designed to speed up our work. It was critical of the work performed
by Second Sight and proposed a new remit: “to determine if sub-postmasters

had been wrongly convicted due to defects in the Horizon system”.

Page 20 of 63
WITNO0420100
WITNO0420100

66.Whilst this accurately describes what MPs wanted, Paula Vennells was
increasingly attempting to steer us away from considering the safety of

convictions.

67.Document [POL00098354] not seen previously by me, is believed to be dated
1 May 2013. It is a proposed briefing note for a telephone call between Paula
Vennells and James Arbuthnot. It makes a number of suggestions about

streamlining the work being carried out by Second Sight.

68. Document [POL00098208] highlights the not inconsiderable challenges that

we all were facing in progressing the agreed spot reviews.

69. Document [POL00098377], not previously seen, is a POL file note of a
telephone conversation between Paul Vennells and James Arbuthnot on 23
May 2013. It refers to the desirability of an interim report probably in July 2013

and a full report by the end of October.

70. It is clear at this point, that Second Sight had established a satisfactory
working relationship with Alan Bates and JFSA and had earned their trust. It is
also clear to me, that there was something of a breakdown of communication

and possibly trust as well, between Second Sight and POL.

Page 21 of 63
WITNO0420100
WITNO0420100

71.To the credit of POL, they did not try to directly interfere with or influence
Second Sight’s reports (other than by withholding potentially relevant
documents), but this was probably at the expense of the effectiveness of the
overall project. With hindsight, the views expressed in these documents now
disclosed to me, probably should have been shared with Second Sight at the

time and a more collaborative approach adopted.

72.What POL did do, to the detriment of our work, was to limit access to relevant
documents. For example, many years later I heard about the Detica Report
and the Swift Advices, both of which are highly relevant to what we were

being asked to do, but these important documents were not disclosed to us.

73.Second Sight continued investigating the agreed thematic issues and issued

its Interim Report on 8 July 2013. [POL00099063]

INTERIM REPORT 8 JULY 2013

74. By this stage, Ron Warmington and I were becoming increasingly concerned
about potential challenges from POL if they didn’t like what we said. We
decided the best way to deal with this was to avoid expressions of opinion and
to prepare a report that was fact based and where we had an audit trail to

source documents, evidencing every significant issue covered in the report.

Page 22 of 63
WITNO0420100
WITNO0420100

75.From memory, an advanced draft of this report was disclosed to POL on 5
July 2013 and a signed copy of our Interim Report released on 8 July 2013.

Page 8 described our Preliminary Conclusions:

“8. Preliminary Conclusions

8.1. This is an Interim Report and there is much work still to be done.

Any conclusions reached at this point will need to be updated in the

light of new information that arises as the Investigation continues.

8.2. Our preliminary conclusions are:
a) We have so far found no evidence of system wide
(systemic) problems with the Horizon software;
b) We are aware of 2 incidents where defects or ‘bugs’ in
the Horizon software gave rise to 76 branches being affected by
incorrect balances or transactions, which took some time to
identify and correct;
c) Occasionally an unusual combination of events, such as
a power or communications failure during the processing of a
transaction, can give rise a situation where timely, accurate and
complete information about the status of a transaction is not
immediately available to a SPMR;
d) When individual SPMRs experience or report problems,
POL’s response can appear to be unhelpful, unsympathetic or
simply fail to solve the underlying problem. The lack of a ‘user

forum’ or similar facility, means that SPMRs have little

Page 23 of 63
WITNO0420100
WITNO0420100

opportunity to raise issues of concern at an appropriate level
within POL;

e) The lack of an effective ‘outreach’ investigations function
within POL, results in POL failing to identify the root cause of
problems and missing opportunities for process improvements;
f) The end of Trading Period processes can be problematic
for individual SPMRs, particularly if they are dealing with
unresolved Transaction Corrections (‘TCs’). The lack of a
‘suspense account’ option means that it is difficult for disputed

TCs to be dealt with in a neutral manner.

76.Contrary to the public position taken by POL, that Horizon operated without

problems, our Interim Report stated:

“6.4. In the course of our extensive discussions with POL over
the last 12 months, POL has disclosed to Second Sight that, in
2011 and 2012, it had discovered "defects" in Horizon online
that had impacted 76 branches.

6.5. The first defect, referred to as the "Receipts and
Payments Mismatch Problem", impacted 62 branches. It was
discovered in September 2010 as a result of Fujitsu's monitoring
of system events (although there were subsequent calls from
branches). The aggregate of the discrepancies arising from this

system defect was £9,029, the largest shortfall being £777 and

Page 24 of 63
WITNO0420100
WITNO0420100

the largest surplus £7,044. POL has informed us that all
shortages were addressed at no loss to any SPMR.

6.6. The second defect, referred to as the "Local Suspense
Account Problem", affected 14 branches, and generated
discrepancies totalling £4,486, including a temporary shortfall of
£9,800 at one branch and a surplus of £3,200 at another (the
remaining 12 branches were all impacted by amounts of less
than £161).

6.7. POL was unaware of this second defect until, a year after
its first occurrence in 2011, it re-occurred and an unexplained
shortfall was reported by an SPMR.

6.8. POL's initial investigations in 2012 failed to reveal the
system defect and, because the cause could not be identified,
the amount was written off. Fujitsu looked into the matter early
in 2013 and discovered, and then corrected, the defect.

6.9. It seems however, that the shortfalls (and surpluses) that
occurred at the first occurrence (in 2011) resulted in branches
being asked to make good incorrect amounts.

6.10. POL has informed us that it has disclosed, in Witness
Statements to English Courts, information about one other

subsequently-corrected defect or “bug” in the Horizon software.”

77.The "Receipts and Payments Mismatch Problem" and "Local Suspense
Account Problem" were disclosed to us by POL in June 2013, just a few days

before we published our Interim Report. I subsequently noticed that a copy of

Page 25 of 63
WITNO0420100
WITNO0420100

"Receipts and Payments Mismatch Problem" was included the hard copy file
relating to the Seema Misra prosecution. In 2024, as a result of seeing the
evidence of Simon Clarke to the Inquiry, I realised that this document was not
disclosed at her trial and had been subject to a Public Interest Immunity

certificate exemption.

78.My overall conclusion at this stage (July 2013) was that Post Office Horizon
was not the robust, error free system claimed by POL. I was also concerned
about the potential loss of integrity caused by working practices within Fujitsu,
such as remote access without the knowledge or consent of individual sub-
postmasters. I was beginning to form the view that no prosecution relying on

Horizon evidence could be safe.

Complaint Review and Mediation Scheme of 2014

79.This scheme started very soon after the publication of our Interim Report,
however the formal notification about the Scheme was not sent out until 27
August 2013. The deadline for applications to the scheme was 18 November

2013.

80.As far as I can recall, I attended all of the meetings of what became known as
the “Mediation Working Group” (“MWG"). Meetings were held at various
locations including the London Headquarters of POL, but occasionally also the
London office of Bond Pearce and Matrix Chambers. We also had telephone

conference calls.

Page 26 of 63
WITNO0420100
WITNO0420100

81.The main purpose of the MWG was to act as a “gatekeeper” for applications
to the Complaint Review and Mediation Scheme (“the Scheme”). Attendees
included representatives from POL, JFSA and Second Sight. Secretarial
support was provided by POL and documents were shared using an online

facility known as Huddle. The Scheme Chairman was Sir Anthony Hooper.

82. It took some time for the Scheme to get going and to prepare application
packs. The way the scheme worked was that each applicant submitted an
application to Second Sight or the JFSA and if confirmed as suitable for
investigation, the applicant could engage a professional adviser on a fixed fee

basis, paid for by POL.

83.There was no limitation on the type of case to be considered by the Scheme,
although it was recognised that either current criminal or civil proceedings

would have to be completed, prior to a case being accepted.

84. The applicant would submit a completed Case Questionnaire Report (“CQR”)
and at the same time POL prepared a Post Office Information Report
(‘POIR”). Second Sight would then review all of the information and prepare a
Case Review Report (“CRR’), which was then considered by the MWG. Once
accepted, the Scheme administrator liaised with the applicant in order to

arrange mediation.

Page 27 of 63
WITNO0420100
WITNO0420100

85.The Scheme operated on a confidential basis, with very limited information
about outcomes being provided to the MWG. About 150 applications to the
scheme were received, of which approximately 136 were approved for

mediation.

86. The preparation of the various reports to the MWG took quite a long time. I
became aware that approximately 20 POL employees were involved in the
preparation of the POIR responses. I also became aware, that even these
POL employees did not necessarily have full access to POL legal files, which

was a major concern to me.

87.1 became aware during the operation of the Scheme that POL probably
regarded me as a troublemaker, as I was constantly pressing for access to the
POL legal files and this was being resisted. I felt quite strongly that
unrestricted access to all of the documents held by POL relating to
prosecutions, particularly the legal files, was necessary if the Scheme was to

operate fairly and successfully.

88.1 remember that at the conclusion of one of the MWG meetings, the acting
POL Head of Legal (Chris Aujard) warned me to be careful about what I said.
He told me that if I said anything that harmed POL, POL would not hesitate to
take legal action against me under the terms of my Non-Disclosure
Agreement (“NDA”) and that I would not be able to afford the legal fees. I took

this as a thinly veiled threat to bankrupt me if I continued causing trouble.

Page 28 of 63
WITNO0420100
WITNO0420100

89. There were three areas that POL seemed to be particularly sensitive about.
These were:
a) access to the full legal files held by POL relating to prosecutions;
b) an analysis of the suspense accounts held by POL; and

c) disclosure to POL by Fujitsu of known problems involving Horizon.

90. Towards the end of the Scheme, POL disclosed to us details of some of the
credits taken to its Profit and Loss account (“P&L”) from a centrally held
suspense account [POL00022773]. POL was unable to give us a breakdown

of these transactions. The credits taken were:

Suspense Account Balances credited to POL
Profit & Loss Account

Year released to P&L £

2014 / 15 year to date £8,000

2013/14 £104,000

2012/13 £234,000

2011/12 £207,000

2010/11 £612,000

Page 29 of 63
WITNO0420100
WITNO0420100

91.1 felt that a possible explanation for these balances was that they represented
credit transactions due to individual sub-postmaster branch accounts, where
alleged losses were charged to sub-postmasters. Shortly after we started
investigating this possibility, our contract with POL (and the Scheme) was

terminated.

Part I Report of 25 July 2014

92. In parallel with our work supporting the Scheme, we published a number of
reports. The Part I Report of 25 July 2014 [POL 00004439] was designed to
provide background information about POL and the Horizon system generally.

Much of the content of this report was provided directly by POL.

93. The report covered the following areas:

a) General information about Post Office, its branches and the role of
Subpostmasters;

b) A description of the training and support functions as well as the Post
Office audit and investigation processes;

c) An overview of the Horizon system and associated equipment;

d) An introduction to the application of double entry accounting in Horizon;

e) Adescription of significant branch operating and reporting procedures
and the associated processing of transactions;

f) An outline of the treatment of losses and surpluses; and

g) An analysis of typical errors.

Page 30 of 63
WITNO0420100
WITNO0420100

94.As far as I can remember, the report was agreed with POL before it was
published. It was designed to provide non-contentious standing information

about the POL Horizon system.

Part 2 Report of 21 August 2014

95.By August 2014 we were coming under increasing pressure from both POL
and MPs to publish an interim report on our findings to date. We were now
investigating the 19 discrete thematic issues we had identified, rather than

individual cases.

96. This report [POL00030160] dealt with the following thematic issues:
a) the contract between the Post Office and sub-postmasters;
b) automated teller machines (“ATMs”);
c) motor vehicle licences;
d) National Lottery;
e) training support and supervision;
f) the helpline;
g) limitations in the transaction audit trail;
h) transactions not entered by the sub-postmaster or their staff;
i) transaction reversals;
j) cash and stock remittances (“REMs”) in and out of the branch;
k) missing cheques;
I) pensions and allowances;

m) surpluses;

Page 31 of 63
WITNO0420100
WITNO0420100

n) cash withdrawals accidentally processed as deposits and other counter
errors that benefit customers at the expense of the sub-postmaster;

©) error and fraud repellency;

P) one-sided transactions;

q) hardware issues;

r) Post Office audit procedures; and

s) Post Office Investigations.

97.As far as I can remember, POL were invited to comment on our draft report

before it was finalised.

Reporting of concerns to Members of Parliament

98. Notwithstanding the terms of our appointment to the Scheme, Second Sight
was originally appointed by a small group of MPs, not POL. By February
2015, I no longer had confidence that POL was taking our concerns seriously
or dealing with them in an appropriate manner. I felt we were dealing with a

cover-up by POL and possibly a criminal conspiracy.

99.1 was concerned about the various threats that had been made to me by POL
concerning alleged breaches of my NDA and my duties of confidentiality.
Accordingly, I had to find a way of communicating my concerns, but which
limited the risk of a legal action against me, or Second Sight, by POL. The
most likely threats appeared to be an action for defamation, breach of

confidence or breach of contract.

Page 32 of 63
WITNO0420100
WITNO0420100

100. I was advised that evidence provided to a Parliamentary Select
Committee attracted Parliamentary privilege and therefore provided a degree

of protection from the risks that I was concerned about.

101. On 19 February 2015 I sent the following to all members of the

Business and Industrial Strategy Select Committee [JARB0000108]:

“BRIEFING NOTE TO BIS Select Committee

1. Introduction

1.1. The purpose of this Briefing Note is to provide Members of the BIS

Select Committee with confidential information supporting my oral

evidence to the Committee.

2. Access to the complete legal files
2.1 In my evidence to the Committee I referred to the need for
Second Sight to have access to the complete, i.e. not redacted,
legal files held by Post Office. Ms. Vennells also referred to Post
Office’s commitment to identifying “Miscarriages of Justice”.
2.2 However, Post Office’s true position on this point was set out
in a letter from Post Office to Second Sight, dated 21 January
2015:
“Post Office does not accept that an analysis of the evidence in
the Applicant’s criminal case, whether served during the course
of that case or not, is either within the scope of the mediation

scheme or something which is within Second Sight’s remit.”

Page 33 of 63
WITNO0420100
WITNO0420100

2.3. It would appear that concern about Second Sight
investigating previous prosecutions by Post Office, is the real
reason behind Post Office’s continuing refusal to provide us with
access to the complete legal files.
2.4. When Second Sight was first appointed by Post Office and
Members of Parliament in July 2012, a number of undertakings
were given by Post Office in order to satisfy MPs that Second
Sight would be able to conduct a truly independent investigation
into the matters of concern.
2.5. Those undertakings included the following:
Unrestricted access to documents held by Post Office
(including documents subject to confidentiality and legal
professional privilege);
No limitation in the scope of work determined necessary
by Second Sight.
2.6. Those undertakings were reflected in the “Raising Concerns
with Horizon” document signed by Post Office on 17 Dec 2012
and sent to the JFSA and Mediation Scheme Applicants. A key
paragraph was:
“In order to carry out the Inquiry, Second Sight will be
entitled to request information related to a concern from
Post Office Limited, and if Post Office Limited holds that
information, Post Office Limited will provide it to Second

Sight.”

Page 34 of 63
WITNO0420100
WITNO0420100

2.7. This statement was intended to accurately reflect the
undertakings mentioned in Paragraph 2.5 above.

2.8. It would appear that many Subpostmasters and Applicants
to the Mediation Scheme will have relied on that paragraph,
when reporting matters to Second Sight. Post Office is clearly no
longer meeting its commitment to provide Second Sight with the
documents requested.

3. The importance of access to the complete legal files

3.1. In a small number of cases we have requested and been
provided with access to the complete legal files. This was before
the policy referred to in Paragraph 2.2 above, was adopted by
Post Office.

3.2. The following represents anonymised extracts from a single
complete legal file held by Post Office, regarding a case that has
been accepted for Mediation. This case involved a charge of
Theft that was withdrawn at trial. “REDACTED” represents the
name of the former Subpostmaster.

a) On 17 May 2006 the Post Office Investigator reported:
“Having analysed the Horizon printouts and
accounting documentation I was unable to find
any evidence of theft or that the cash figures had
been deliberately inflated.” (My emphasis)

And
“The prepared statement seems to intimate that

she didn’t receive adequate training at the time

Page 35 of 63
WITNO0420100
WITNO0420100

and that the manuals were old and out of date. It
also suggests that she didn’t receive any training
in respect of other matters.
It also refers to an alleged £1,500 error, which
doubled to £3,000 when attempts were made to
correct it and another error of £750. No dates are
supplied in respect of these alleged errors. It also
suggests that ‘The Post Office systems are
shambolic’ and details alleged problems
encountered. It states that all staff use the same
Horizon user name, again citing lack of training as
the reason for this.” (My emphasis)
In my opinion, this indicates that a charge of Theft would
be likely to fail, because Post Office’s own Investigator
found no evidence to support such a charge. In addition,
the admitted password sharing created a situation where
it was not possible to link any loss or theft to a named
individual, an essential element in proving a charge of
Theft. No more detailed investigation was ever carried
out by Post Office.
b) On 26 June 2006 the Principal Lawyer of the Criminal Law
Division of Royal Mail (the Prosecuting Authority on behalf of
Post Office at the time) stated:
“In my opinion the evidence gave rise to offences of theft

/ false accounting”

Page 36 of 63
WITNO0420100
WITNO0420100

c) On 15 November 2007 the Principal Lawyer of the Criminal
Law Division of Royal Mail advised:
“As you know there has been some discussion as to whether or
not pleas to false accounting would be acceptable. I note this
would be agreeable providing that REDACTED were to repay
the full amount.”
d) REDACTED was subsequently charged with 1 count of Theft
and 14 charges of False Accounting
e) On 16 November 2007 the Principal Lawyer of the Criminal
Law Division of Royal Mail stated:
“I have forwarded the memo to Counsel. I have informed him
that whilst there is no outright objection to proceeding with False
Accounting, there is a concern as to recovery of Money. We
have to date been able to recover where False Accounting only
is charged though on one or two cases the Defence will argue
against. Whilst a plea to Theft would be preferable ,in the event
of non-payment the intent would be to proceed to confiscation.”
f) The forwarded memo stated:
“lam never confident with False accounting charges in
relation to recovery under POCA 2002 and the theft
charge makes life so much easier. The defendant has
General Criminal Conduct under the proposed charges
and this would be so with just the false accounting
however we have been challenged once before when

proceeding to POCA where only false accounting was

Page 37 of 63
WITNO0420100
WITNO0420100

charged, and I would probable be more inclined to except
Particular Criminal Conduct when dealing with
confiscation in that scenario. I fully understand the
balance of cost in court time against recovery and if the
charge of theft was dropped for a guilty plea then I would
still believe it appropriate to follow to confiscation...”
g) On 19 November 2007 REDACTED pleaded guilty to 14
counts of False Accounting. The Prosecution agreed to leave
the count of Theft on file, providing prompt repayment of the
losses by REDACTED was made.
A letter dated 19 November 2007 from the Principal Lawyer of
the Criminal Law Division of Royal Mail stated:
‘it has been made clear to the Defence that there must be
some recognition that the Defendant had the money short
of theft and that a plea on the basis that the loss was due
to the computer not working properly will not be
accepted.” (My emphasis)
3.3. This new evidence causes me a number of concerns, all or most of
which would appear to be in breach of the Crown Prosecution Service
(“CPS”) Guidance to Prosecutors, which Post Office and Royal Mail are
required to comply with.
a) The Prosecution knew that there was insufficient evidence to
support a charge of Theft, but proceeded with it nonetheless.
b) The offer by the Prosecution to remove the charge of Theft

was used to put pressure on REDACTED to plead guilty to the

Page 38 of 63
WITNO0420100
WITNO0420100

False Accounting charges, even though the Prosecution knew
that a charge of Theft was likely to fail.
c) The threat of proceeding with a charge of Theft was used to
put pressure on REDACTED to agree to pay the losses
identified and to avoid a custodial sentence, normally associated
with a charge of Theft in these circumstances.
d) The threat of proceeding with a charge of Theft was primarily
to assist in the recovery of losses, and not in the interest of
Justice.
e) The Prosecution insisted that as part of the agreement to
drop the charge of Theft, that no mention of alleged problems
with the Horizon computer system would be made.
4. Conclusion
4.1. The new facts that have come to light as a result of examining a
single complete legal file, have identified a number of issues that
indicate:
a) Possible misconduct by a Prosecutor on behalf of Post Office;
and
b) A possible miscarriage of justice.
4.2. In my view, this analysis of a single complete legal file, has
demonstrated the benefit of doing so; particularly bearing in mind the
stated objective of Post Office to thoroughly investigate possible
miscarriages of justice.
4.3. Second Sight will therefore, continue to press for access to the

complete legal files and other documents that we believe are

Page 39 of 63
WITNO0420100
WITNO0420100

necessary for Second Sight to conduct an independent investigation

into the matters of concern.

102. In order to protect the identity of the sub-postmaster I referred to them
as REDACTED in this report. However, I can now say that the sub-postmaster
referenced here was Jo Hamilton, who became the lead appellant before the

Court of Appeal.

Non-disclosure of potentially exculpatory material

103. Out of the approximately 10 cases where we were provided with full
access to the POL legal files, there were at least two cases where in my
opinion, there was compelling evidence that potentially exculpatory material
had not been disclosed to the applicant either at trial, or subsequently. I
regarded this as either professional misconduct or potentially, criminal

conduct. The two cases were Jo Hamilton and Seema Misra.

104. In the case of Seema Misra, the potentially exculpatory material was
referenced in our Interim Report [POL00099063]. (“Receipts-Payments
Mismatch Issue Notes.pdf and “Correcting Accounts for Lost

Discrepancies.pdf’)

105. I have recently learned that at the time of Seema’s prosecution in 2010

(or subsequently), POL made a Public Interest Immunity application to not

Page 40 of 63
WITNO0420100
WITNO0420100

disclose these documents. The Pll application was granted and the

documents were not disclosed to Seema Misra.

106. In the case of Jo Hamilton, the potentially exculpatory material was
referenced in our final Case Review Report dated 24 March 2015

[POL00063517].

107. Our report referred to a document titled: “POL_Security
Report_PT_012.pdf” [POL00044389] which was listed on Page 8 of the Post
Office Investigation Report (“POIR”) prepared by POL [POL00034551]. It was

described as “Copy of security team report”

108. The Security Team Report stated:

“Having analysed the Horizon printouts and accounting
documentation I was unable to find any evidence of theft or that

the cash figures had been deliberately inflated.”

109. Notwithstanding this potentially exculpatory evidence from a POL

investigator, Jo Hamilton was charged with theft and false accounting.

110. One of the reasons that I was confident that it was quite proper to
disclose “M035_POL_Security Report_PT_012.pdf’ to Jo Hamilton, was that it

was listed in the POIR prepared by POL [POL00034551].

Page 41 of 63
WITNO0420100
WITNO0420100

111. On 2 June 2015 I received a letter from Rodric Williams of POL legal
department asserting privilege over the document disclosed to Jo Hamilton
[POL00025188]. I found this assertion to be absurd and to be immensely
worrying. It was beginning to look more like a cover-up than a genuine

concern about legal professional privilege.

112. On 3 June 2015 I replied to Roderic Williams [POL00065542] stating
that the document in question had quite properly been disclosed to the MWG

and that no claim of legal professional privilege had been made.

113. At this time POL were responsible for the administration of the MWG
and for distributing documents to applicants, including Jo Hamilton. The main
person co-ordinating this work was Belinda Crowe, a POL employee or

contractor.

114. POL appeared to be determined to avoid disclosing the Security Team
Report to Jo Hamilton, notwithstanding the fact that the final Case Review
Report [POL00063517] disclosed to Jo Hamilton had quoted from the POL

Security Team Report.

115. POL’s solution to this impasse was to create a new POIR that made no
mention of the POL Security Team Report. (“M035 — POL_Case Review

Summary (Revised exec summary)_PT.pdf”) [POL00034782] .

Page 42 of 63
WITNO0420100
WITNO0420100

116. The previous reference to “M035_POL_Security Report_PT_012 -
Copy of security team report” was now replaced by “M035_POL_012_Security

Interview_PT - Copy of security team interview”.

117. I only found out about this because Jo Hamilton contacted me to say
she hadn't been provided with a copy of the POL Security Team Report

quoted in the M035_FINAL_CRR_revised.pdf [POL00063517].

118. I was shocked that a senior POL lawyer appeared to be involved in
what appeared to me, to be a conspiracy to pervert the course of justice (or
similar criminal offence). My immediate thought was, if POL is prepared to do
this with Jo Hamilton, how many other cases have also been treated in a

similar way?

119. I was delighted to see a few years later that Jo Hamilton was the lead
appellant before the Court of Appeal considering a number of Horizon

convictions.

The termination of the Scheme and the termination of Second Sight’s

appointment

120. On or about 10 March 2015, I was attending a meeting with the POL

finance team in their Head Office in Old Street, London. I met briefly with Jane

Page 43 of 63
WITNO0420100
WITNO0420100

MacLeod, the POL new Head of Legal, who handed me two letters. She
explained that the letters were formal notice of termination of the Initial
Complaint Review and Mediation Scheme and also the termination of Second

Sight’s appointment [POL00000216] and [POL00224327].

121. Jane explained that notwithstanding the termination of Second Sight's
appointment in relation to the Scheme, Second Sight was invited to continue
providing services to applicants to the Scheme and we continued to do this for

a number of months.

122. Jane told me that the reason the Scheme and our appointment was
being terminated was that POL had agreed that all outstanding applications

would be mediated.

123. I believed that the real reason for the termination of our appointment
was to use James Arbuthnot’s words — “Second Sight was getting too close to
the truth” [INQ00001127]. I also believe that POL wanted to stop Second
Sight finding the truth about the substantial balances in a centrally held
suspense account that were taken to the benefit of the POL P&L account over

a number of years and as referred to in paragraph 90 above.

124. In addition to terminating our appointment, POL withdrew their consent
for us to discuss our work with MPs including James Arbuthnot. This was

increasingly looking like a POL cover-up.

Page 44 of 63
WITNO0420100
WITNO0420100

Part 2 Report of 9 April 2015

125. With the termination of the Scheme and of our appointment, it was
necessary to publish our updated Part 2 Report as quickly as possible. As far
as I can remember, the report was disclosed to POL before it was published
and their comments invited. Our investigations into cases being considered by
the Scheme had not been completed and about 20 cases were still

outstanding as of 9 April 2015.

126. This updated version of our Part 2 Report [POL00029849] was much

longer than the previous version. It included the following qualification:

2. Limitation of Scope in Work Performed
2.1. We have experienced significant difficulty in obtaining access to a
number of documents we believe are necessary for the purposes of
our investigation, notwithstanding Post Office’s commitment to make
requested documents available to us. The documents requested
from Post Office fall into three main categories:
a) the complete legal files relating to investigations
or criminal prosecutions commenced by Post
Office that relate to Applicants;
b) the complete email records relating to a small

number of Post Office employees working at the

Page 45 of 63
WITNO0420100
WITNO0420100

Bracknell office of Fujitsu in 2008; and

c) detailed transactional records relating to items
held in Post Office's Suspense Account(s) and to
disputed transactions in a number of third party

client accounts held by Post Office.

127. On the subject of remote access and unauthorised changes to branch
accounts we said the following:
“2.12. We deal with this matter in more detail in Section 14 of
this Report. Our current, evidence based opinion, is that Fujitsu
/ Post Office did have, and may still have, the ability to directly
alter branch records without the knowledge of the relevant

Subpostmaster. “

128. We also said:
“3.1. The limitation in scope reported above has, in our
opinion, significantly restricted our ability to complete our
investigation into some of the issues commonly raised by
Applicants to the Scheme. It is particularly regrettable that two
of the issues raised: access to the complete legal files and to the
Bracknell emails, appear to represent a policy decision, taken at
a senior level within Post Office, which is contrary to the
undertakings previously provided to Second Sight, to Applicants,

to the JFSA and to MPs.”

Page 46 of 63
WITNO0420100
WITNO0420100

129. Our Conclusions section was as follows:

CONCLUSIONS

26.1) When we started our work on these important matters in
July 2012, we believed there was a shared commitment with
Post Office to “seek the truth” irrespective of the consequences.
This was reflected in us being provided with unrestricted access
to highly confidential and sensitive documents, including legal
advice relating to individual cases. This position was recognised
and well received by other stakeholders, including the Rt. Hon.

James Arbuthnot MP and the JFSA.

26.2) However, as time progressed, and particularly in the last
18 months, it has been increasingly difficult to progress our
investigations due to various legal challenges by Post Office.
There have been considerable delays in receiving responses to
requests for information and legal issues have been raised, such
as Data Protection and Legal Privilege, as being the reason

various documents could no longer be provided to us.

26.3) We found that types of document, previously provided to
us without restriction, were no longer being provided. Some of
these documents were also not being provided to Post Office’s

in-house team of investigators.

26.4) We can only conclude that this represented a policy
decision by Post Office at a senior level, possibly based on legal
advice. We consider this regrettable, particularly in the light of
assurances previously provided to ourselves, MPs and the

JFSA.

26.5) In expressing our disappointment in finding ourselves
unable to complete our independent investigation in the way that
we considered necessary, we wish to place on record our
appreciation for the hard work and professionalism of Post
Office’s in-house team of investigators, working for Angela Van

Den Bogerd, Post Office’s Head of Partnerships.

26.6) Our work would have been much harder and taken much
longer without the high quality work carried out by this team.
We have also received excellent support from the administrative

team set up by Post Office to support the Working Group.

26.7) We also valued the guidance provided by the Mediation
Working Group, chaired by Sir Anthony Hooper, until its abrupt

dissolution on 10 March 2015.

26.8) We have described in this report the results of our

investigations (some of which are incomplete) into the issues

Page 48 of 63
WITNO0420100
WITNO0420100

and concerns raised by multiple Applicants. As we have
previously stated, when looking at the totality of the ‘Horizon
experience’ we remain concerned that in some circumstances
Horizon can be systemically flawed from a user's perspective
and Post Office has not necessarily provided an appropriate

level of support.

26.9) We believe that Post Office should be much more alert to
possible problems with Horizon and encourage its staff to
develop a much greater degree of ‘professional scepticism’ in

this regard.

26.1) We hope that this report, although incomplete in a number

of important respects, will shed some light on the important

issues raised by the 136 Applicants accepted into the Mediation

Scheme.

130. As James Arbuthnot said to Parliament — POL “sabotaged” the

Mediation Scheme. He also said he regarded the conduct of POL as

“duplicitous”. I agree with those comments.

The instruction by POL to destroy documents

131. On 27 July 2015 POL wrote us in the following terms:

Page 49 of 63
WITNO0420100
WITNO0420100

“Demand
For the avoidance of doubt, Post Office demands, pursuant to
clause 6.1.4 of your Engagement Terms, that within 7 days of
the date of this letter Second Sight:
1. delivers up to Post Office all Confidential Information in
its original format, including all versions of the same
information in any different formats;
2. permanently and securely destroys all copies of that
Confidential Information retained by Second Sight; and
3. confirms in writing that it has complied fully with the

demands made above.”

132. Many of the documents held at this stage were in hard copy format and
it took some time to get everything packed up and delivered to POL. As far as
electronic documents were concerned, I was determined that POL should not
be able to airbrush our work out of POL history and it took some time to
prepare the master database of electronic documents, prior to transfer to

POL.

133. I had in mind, that some of our work and the documents obtained,
would be useful to e.g. the Criminal Cases Review Commission (“CCRC”) and
I tried to ensure that undertakings were provided by POL to preserve
documents. I also believed that the master list of approximately 34,000

documents would be a useful way of holding POL to account.

WITNO0420100
WITNO0420100

The use of the term “systemic”

134. The term “systemic” (in the context of our work for POL and the
Scheme) was first used by Susan Crichton — see paragraph 23 g) above. I
took it to mean “system wide” or “of a whole system” i.e. the Oxford English

Dictionary definition.

135. However, as our work for POL and the Scheme progressed, I became
aware that Alan Bates and the JFSA were using the term “systemic” to mean

“caused by the system”.

136. We tried to clarify the meaning of the term “systemic” in our various

reports, but I regret that we were not entirely successful in doing this.

SLAPP type threats by POL

137. Strategic Lawsuits against Public Participation (“SLAPP”) were not
widely recognised in 2013, but POL frequently threatened Second Sight (quite
falsely) with allegations of breach of confidence and on one occasion
threatened to report us to the Institute of Chartered Accountants in England
and Wales for an alleged breach of its Code of Ethics because we had

provided an update to one of the MPs who had appointed us in the first place.

138. Even now, the NDA waiver (by POL in relation to Second Sight) is

qualified and states that POL:

Page 51 of 63
WITNO0420100
WITNO0420100

(b) consents to the release of Second Sight from any
confidentiality obligations to Post Office Limited for the purposes
of disclosing material to the Inquiry, making any submissions to
the Inquiry and/or giving evidence to the Inquiry to assist the
Inquiry to fulfil its Terms of Reference, subject to seeking Post
Office Limited’s prior consent in relation to any material that may
be subject to legal professional privilege (in order to ensure such
material is treated in accordance with Post Office Limited’s
statement on waiver dated 15 November 2021), as outlined in
the letter from Post Office Limited’s representatives dated 7

December 2021.

139. This requires Second Sight to seek POL’s prior consent in relation to
any material that may be subject to legal professional privilege such as the
report disclosed to Jo Hamilton and possibly, even correspondence between

POL and Second Sight.

Reflections and further observations

140. My work for POL and the Scheme was probably the most challenging
in the 40 years of my career as a Chartered Accountant. One of the reasons it
was challenging was that POL would say one thing in public, and then do

something different in private.

Page 52 of 63
WITNO0420100
WITNO0420100

141. An example of this was Paula Vennells (POL CEO) statement to the
Parliamentary Select Committee in February 2015 that our work had found

“no evidence of miscarriages of justice” and

“it was important that we surface any miscarriages of justice”.

142. Paula Vennells frequently and consistently, attempted to steer Second
Sight away from investigating potential miscarriages of justice. Another
example was POL’s attitude towards criminal convictions and the mediation

Scheme.

143. The Scheme documentation made it quite clear that an applicant with a
criminal conviction was potentially eligible for the Scheme. POL seemed to

disagree with this view and often challenged these applications.

144. When I first met Paula Vennells, she told me that POL was the nation’s
most trusted brand with a history of over 400 years. As our work continued, I
increasingly formed the view that because of this history, POL somehow felt it
was above the law and didn’t need to comply with e.g. the Criminal Procedure
and Investigations Act 1996, which set out the disclosure requirements for
Prosecutors (including those conducting private prosecutions) as was the

case with POL.

145. At one point I was told that there are more people working in the POL

Public Relations department than were working in the POL legal department.

Page 53 of 63
WITNO0420100
WITNO0420100

This appeared to me to be an inappropriate business priority and one that was

probably unsustainable.

146. I formed the view that POL was constantly sabotaging our efforts “to
seek the truth irrespective of the consequences”. Requests for documents
were either ignored or responses were excessively delayed. Unjustified claims

of legal professional privilege were used to justify withholding documents from

us.

147. Towards the end of the mediation Scheme, some questions asked 12
months earlier had still not been answered. Protecting “the brand” was the
priority, not supporting sub-postmasters. I felt POL had lost its way and it
needed fundamental overhaul with a new focus placed on supporting sub-

postmasters.

148. Many aspects of the individual prosecutions we investigated just didn’t
make sense. For example, in none of the cases that we looked at did we find
any evidence of personal gain or benefit. This may indicate that the alleged
loss was not real and was more likely to have been caused by a faulty
computer system. Also, there was extensive vetting of sub-postmasters prior
to appointment. POL would have us believe that significant numbers of sub-

postmasters had suddenly become career criminals. I found this implausible.

Page 54 of 63
WITNO0420100
WITNO0420100

149. In the course of our work, we found that up to 10 POL employees were
based in the offices of Fujitsu in Bracknell. We never had a clear explanation
of what they were doing and all of our requests for access to full and detailed
email records at the relevant time (which could have helped answered this

question) were denied.

150. I became aware in about September 2013 that Susan Crichton had left
POL. I wasn't briefed about this, but I do recall observing how upset Susan
was about the way that she was being treated by POL. I remember one
afternoon she was due to present a paper to the Board, but was never called
into the meeting. She told me afterwards that she felt like “a naughty
schoolgirl”. I was therefore not surprised to hear a few weeks later that she

had resigned.

151. I have been asked to comment on the various audio recordings
obtained by Second Sight. To put this into context, I would say that our work
needed to be supported by evidence and that in some cases that evidence
was provided orally, either in face-to-face meetings or in telephone calls. In
the interest of accuracy, recordings were often made so that a file note could

be prepared or evidence of key discussions retained.

152. Ideally, all parties to the conversation would be aware that a recording
was being made, but it was not always possible to do this. There was

sometimes a significant risk that if a witness was aware that a recording was

Page 55 of 63
WITNO0420100
WITNO0420100

being made, this would affect the willingness of person to provide evidence or

the veracity of the evidence being provided.

153. Decisions were made on a case-by-case basis, this but we usually
ended up recording key conversations, particularly if those conversations

were likely to include significant evidence.

154. I only had one meeting with Fujitsu, as mentioned in paragraph 43
above. I then had some limited email contact with Gareth Jenkins. In the
course of supporting the mediation Scheme I had frequent contact with POL
lawyers, both internal and external. My only contact with Members of
Parliament was in public meetings. My only contact with the CWU or the
National Federation of Sub-postmasters was in public meetings. My main
contact with the Justice for Sub-postmasters Alliance was in mediation

Scheme meetings.

155. As far as I can recall, all of our reports were marked “Confidential, not
for publication’. We recognised however, that due to the public interest in our
work, these reports were likely to leak to a wider audience. Somewhat
surprisingly, POL decided to publish our Interim Report on a POL website.

The JFSA published all of our reports on its website.

Page 56 of 63
156.

WITNO0420100
WITNO0420100

I have had no contact with POL following termination of our contracts

and I have no knowledge as to whether or not our recommendations were

implemented.

157.

About three years ago I spoke at a legal conference about our work for

POL. At the end of my talk, I listed a number of questions that I believed

needed to be answered. They were:

a)

b)

¢)

d)

e)

9)

Was prosecution policy within Post Office and Royal Mail influenced by a
desire to maximise value prior to an eventual sale or mutualisation
proposal?

Did Post Office continue to destroy documents after the litigation hold
instruction was issued in 2012?

Why were key documents such as the Clarke Advices and the Detica
report not disclosed to Second Sight by Post Office?

When were these documents disclosed to the Board of Post Office?
Why did no one take action in 2013 when Second Sight first raised many
of our concerns in our Interim Report that was published by Post Office?
Why was the Select Committee not more effective in following through
on their excellent work in 2015?

Was the failed ICL / Pathway project (Horizon’s predecessor system in
1998) a contributing factor to the bugs, errors and defects now

identified?

Page 57 of 63
WITNO0420100
WITNO0420100

h) Did the Board of Post Office approve the disastrous litigation strategy,
including the recusal application in the Group Litigation Order (“GLO”)
trial?

i) Did the two Government nominated directors on the Board of Post Office
support or approve the approximately £130 million of legal costs incurred
by Post Office in the GLO trial?

J) Was this regarded as value for money?

k) Was there a cover-up within Post Office and or Government of the

disastrous decision making within Post Office?

158. These questions appear to be as relevant now, as when I first raised

them more than three years ago.

159. I have been asked to reflect on what I would have done differently in
respect of the matters covered in this statement. I think a significant weakness
in our relationship with POL (and the Scheme) was the lack of independent
oversight. Despite being owned by the Government, POL is treated as an
autonomous “arms-length body”. There was little or no external scrutiny of the
board or its decision-making. The Government appointed the Chairman of
POL and also two non-executive directors. It probably would have been better
if Second Sight had had a direct reporting line to the POL Chairman and the

POL non-executive directors.

160. There was one other matter that I wish to bring to the attention of the

Inquiry. That is the provision of a whistleblowing facility. If I had been an

Page 58 of 63
WITNO0420100
WITNO0420100

employee of POL, various protections would have been available to me.
However, as a contractor operating under a draconian non-disclosure
agreement, no equivalent protections were available to me. I regard this as
regrettable, and I do hope that the Government considers legislation to

address this omission.

161. I'd also like to say something about accountability. Notwithstanding the
fact that many of these matters happened more than 10 years ago, no one
has been held to account. I do hope that the Inquiry makes recommendations

in this regard, including director disqualifications and sanctions by appropriate

professional bodies.

162. Finally, I’d like to say something about to whom we owed a duty. We
tried to go where the evidence took us, but increasingly we were finding
evidence of questionable conduct by POL, some of which, in my opinion, was

probably criminal.

163. In the course of our work, I increasingly felt that our overriding duty
was, in a phrase attributed to Alan Bates, to help “the skint little people” who

didn’t have a voice and had been so badly treated by POL.
