POST OFFICE HORIZON IT INQUIRY

FIRST WITNESS STATEMENT OF PETER JAMES SEWELL

I, MR PETER JAMES SEWELL, will say as follows:

INTRODUCTION
1. I am a former employee of Fujitsu Services Limited (“Fujitsu”), having left

the company in November 2009.

2. This witness statement is made to assist the Post Office Horizon IT Inquiry
(the “Inquiry”) with the matters put to me in a Rule 9 Request dated 26 July
2023 (the “Request’), to the extent I have or had direct knowledge of such

matters.

3. The topics covered by the Request concern events that occurred over 13
years ago and relate to audit data from the Horizon IT system (“Horizon”)
and audit queries (also known as audit retrieval queries or “ARQs’”). I have
tried to remember these matters to assist the Inquiry as much as possible,
however, due to the time that has passed, my recollection is limited. For this

reason, the content of my witness statement focuses largely on the

Page 1 of 18
WITNO9710100
WITNO9710100

documents that the Inquiry has referred me to in the Request, which I have

referenced below using the Inquiry’s Unique Reference Numbers.

4. ! was assisted in preparing this statement by Morrison Foerster, the

recognised legal representatives for Fujitsu in the Inquiry.

PROFESSIONAL BACKGROUND
5. I joined ICL in 1990. In late 1997, I first joined ICL’s Post Office Account team
(‘POA’) as a Project Manager working on various tasks. These included
managing a development team who wrote the code for auto configuration
whereby a counter PC was switched on and introduced to the estate,
managing a third-party supplier who developed the roll out program, and
managing a development team to provide a training facility on the counter. I
would also interview staff applying for jobs on the Horizon project. My

manager at the time was Dick Long.

6. In 2002, I joined the POA security team in a similar capacity as a Project
Manager. My work in this role included writing an anti-virus implementation
procedure via a change proposal to make it ready to introduce to the live
estate. I was also responsible for sample testing the pin pads prior to release
to the outlets and maintaining a record of units tested and the test results. I
provided support to the security manager, Bill Mitchell, who was later

replaced by Brian Pinder.

7. During 2007, the security team was split into policy and operations teams,
both reporting to a new security manager, Howard Pritchard. At this point I

had the role of Operations Team Manager. My responsibilities were

Page 2 of 18
WITNO9710100
WITNO9710100

managerial in nature, namely business as usual tasks and supporting Mr

Pritchard.

8. A summary of my professional background, including a summary of my

qualifications and career (prior to joining Fujitsu) is set out below.

Organisation Qualification or Role(s) Period

Southend Municipal College I O Levels 1970

Carreras Rothmans Computer Operator 1970-1978
Computer Programmer

Ford Motor Company Computer Programmer 1978-1980

Southend Borough Council I Senior Programmer 1980-1990
Development Manager

BACKGROUND
9. The Inquiry has asked me to set out the role I had in relation to each of the

following matters in connection with Horizon, both in its first iteration (known

as “Legacy Horizon’) and the second iteration (known as “HNGx’):

a. Post Office Limited (“POL”) disciplinary matters;

b. matters relating to those accused of criminal offences;

c. matters relating to criminal or civil proceedings;

d. witness evidence in any proceedings; or

e. the extraction of audit data.

10. In responding to this question and setting out my role, the Inquiry has

referred me to the following documents,

which

have reviewed:

FUJ00122130, FUJ00122131, FUJ00122134, FUJ00122151,
FUJ00122152, FUJ00122153, FUJ00122154, FUJ00122189,
FUJ00122190, FUJ00122197, FUJ00122198, FUJ00122203,

FUJ00122204, FUJ00122217 and FUJ00122218.

I did not have a role in relation to the matters listed in subparagraphs 9(a)-
(d) above. In relation to subparagraph 9(e), in 2007, I became the Operations
Team Manager within the security team (as noted above), overseeing
Penelope (Penny) Thomas, Andy Dunks and Neneh Lowther. My
responsibilities were managerial only. Ms Thomas was a specialist in ARQs
and reported to me, which included providing weekly updates regarding
outstanding ARQs and court dates. However, I did not have a personal role

in relation to the extraction of audit data (i.e., I did not perform ARQs myself).

The Inquiry has also asked me to set out the nature of my working
relationship with Gareth Jenkins, Penny Thomas and Anne Chambers and
to detail what I understood to be their roles in respect of matters relating to

the provision of evidence in court proceedings. I have set this out below.

a. Gareth Jenkins was an “Applications TDA (Technical Design Authority)”;
he provided the security team (mainly Ms Thomas) with technical advice

and guidance and provided evidence in court.

b. Penny Thomas was in litigation support, providing POL with ARQ data.

Ms Thomas was an ARQ specialist and a member of the security team.

c. Anne Chambers was a technical designer who worked in the Software

Support Centre (“SSC”). Mrs Chambers provided the security team

Page 4 of 18
WITNO9710100
WITNO9710100

(mainly Ms Thomas) with technical support advice and guidance and

provided evidence in court.

RELATIONSHIP WITH POL

13. The Inquiry has asked me to describe any circumstances in which I would
have contact with POL in relation to issues concerning Horizon, including the

relevant contacts and the nature of my relationship.

14. I had contact with Sue Lowther, the POL Security Manager. I had detailed
knowledge of the Horizon project, including the relevant people, their roles,
and where to find information, and so would attend security meetings
between managers, Bill Mitchell (later, Brian Pinder) in the POA security

team and the POL security team on a monthly basis to provide support.

15. I liaised with Alan Simpson at POL to review incident management, mainly
of counter down time. I worked directly with the POA customer service team

and so could provide Mr Simpson with information on the counters.

16. I was also in contact with Graham Ward at POL, and his manager Dave
Posnett. Mr Ward was the Casework Manager who requested ARQs and Mr
Posnett was the Fraud and Risk Manager. Mr Ward liaised directly with Ms
Thomas on ARQ matters, and he regularly visited ICL’s Feltham and then
Bracknell offices to meet with Ms Thomas. When I became the Operations
Team Manager in the security team, I wanted to meet the POL team and I
believe Ms Thomas and I had at least two meetings with Mr Ward and Mr
Posnett. I do not recall discussing the specifics of ARQ data with Mr Ward or
Mr Posnett; while I was Operations Team Manager, Mr Ward continued to

liaise with Ms Thomas in relation to this.

ARQ DATA FROM HORIZON AND THE PROSECUTION SUPPORT SERVICE
17. I The Inquiry has asked me to set out my recollection as to the process for
providing audit data to POL and explain the structure and function of Fujitsu’s
Prosecution Support Service and my role in relation to the service. The
Inquiry has also referred me to FUJ00155212, FUJ00155214 and

FUJ00155413, which I have reviewed.

18. I recall that Fujitsu had contractual requirements with respect to the provision

of audit data, which included:

a. the retrieval and analysis of archived Riposte message store data,

including event logs, and calls to the Horizon Helpdesk;

b. responding to ARQ requests from POL for Horizon branch transaction

data and the retrieval of event logs and Horizon Helpdesk calls; and

c. providing witness statements and attending court when requested to

support the ARQ data supplied.

19. I did not have a direct role in relation to the provision of ARQ data to POL,
however, as noted above at paragraph 11, I was Ms Thomas’ line manager
in 2007. Ms Thomas was the security team member primarily responsible for

the provision of ARQ data to POL.

20. I do not know if the processes described above varied in relation to Legacy

Horizon and HNGx.

21. — In relation to the structure and function of the Prosecution Support Service,

there was one security team member who primarily provided this service with

Page 6 of 18
WITNO9710100
WITNO9710100

another team member to provide back-up support when needed. These two
security team members would respond to ARQ requests from the POL
Casework Manager and carry out data extractions from audit files. This data

was then sent securely to POL via a CD-ROM.

22. The technical support for this role was primarily Gareth Jenkins, with the help
of various technical support staff within the Horizon technical teams,

including the SSC.

ARQ PROCESS ISSUES
The incident at Craigpark and the “ARQ Service Issue”

23. The Inquiry has asked me for a detailed account of (i) an incident that
occurred at the Craigpark Post Office branch (FAD code 141832)
(‘Craigpark”) and how it related to the ARQ process and the reliability of
data, (ii) the approach to witness evidence that followed the issue at
Craigpark, and (iii) a certain issue or issues regarding ARQ data variously
referred to as an “ARQ Service Problem”, “ARQ Service Issue”, “Prosecution
Support Urgent Issue” and a “Security Incident” in the 2008/early 2009 period
(‘ARQ Service Issue”). In responding to these questions, I have reviewed
the following documents as referenced in the Request: FUJ00154823,
FUJ00154824, FUJ00154841, FUJ00154842, FUJ00155455,

FUJ00155399, FUJ00155400 and FUJ00122604.

The ARQ Service Issue was related to the incident at Craigpark. The incident
at Craigpark concerned an event log issue that highlighted errors with the
End of Day (“EOD”) process which caused some transactions to freeze and
create an event error. The issue identified at Craigpark raised questions

regarding the integrity of data supplied to POL as part of the ARQ service.

Having reviewed contemporaneous records regarding the incident at
Craigpark (for example, FUJ00155397), I recall that the issue was identified
following a detailed technical investigation by Fujitsu technical staff, who
found out that transactions running during the EOD process had caused a
lock in processing and a Riposte error event was written to the event log. It
was identified that this problem had been caused by a previous bug fix, which
was introduced into Legacy Horizon’s live estate in May 2007. Whilst this
investigation was running, a manual exercise was carried out to examine the
event log data from ARQ data associated within the dates of May 2007 and

November 2008.

I became aware of the issue when error events were discovered whilst
examining event data during an ARQ extraction for Craigpark. There were

several meetings and discussions between Mr Jenkins, Mrs Chambers and

Page 8 of 18
WITNO9710100
WITNO9710100

Ms Thomas, and other managers and support staff. I was usually invited to
these meetings; however, my input was very limited as I did not always
understand the technical details in relation to the ARQ extraction. As
manager, my objective was to find out what went wrong and identify the
appropriate individuals to resolve the issue. The task of resolving any issues
were left to the technical staff, including those I have named above. There
were many meetings that took place to find a resolution to the problem; these
were mainly between the technical staff. I cannot recall who attended these

meetings, but I believe some of the meetings were documented.

When the error was identified, it raised questions regarding the integrity of
ARQ data previously supplied to POL. Previous ARQ data was analysed and
events stripped out to check other event errors. A change proposal was then
raised by Alan Holmes to incorporate this manual process of performing
additional counter event checks into the ARQ service to enable analysis of
counter event messages (as shown in FUJ00155272) and check for any
other event errors. As the change proposal concerned the security team’s
function, it required a sponsor/owner from the security team, and I was made
sponsor for this particular change proposal. As sponsor of the change
proposal, I was invited to meetings to discuss the wording of the change
proposal, but again my input was very limited as I lacked the technical
knowledge. The meetings were run by Mr Holmes, and individuals like Ms
Thomas and possibly Mr Jenkins would have been present. The change
proposal was enhanced to incorporate the manual process into the ARQ
application and remove manual intervention in the ARQ process for the

HNGx solution. Once the analysis of the problem was completed, Fujitsu’s

Page 9 of 18

29.

WITNO9710100
WITNO9710100

senior manager of the POA customer service team, Steve Denham, was
given a presentation of the change proposal and why it was being raised.
Once the change proposal was approved, the work on implementing the
changes could begin and changes to the HNGx ARQ application could be
introduced. I do not recall any discussions regarding POL’s likely reaction to

the proposed changes.

Following the discovery of the additional event error (noted above at
paragraph 25), there was discussion over amending the wording of the
witness statements provided by Fujitsu to POL to include the additional
checks. There were several meetings (some of which I was present at), and
emails exchanged on how to make these changes. From reviewing the
documents provided to me by the Inquiry, it looks like no substantial changes
were made to the witness statement to reflect the changes to the ARQ
service. There may have been smaller revisions made to the witness

statement, but I do not have any recollection of this.

I! believe POL were informed of the ARQ Service Issue and the change
proposal once the full impact of the potential problem was established. In
relation to POL’s involvement in investigations relating to the issue, there
were emails exchanged between Fujitsu and POL discussing the problem.
The problem was recognised as sensitive as the event errors raised
questions regarding the integrity of ARQs. I believe the POL legal team were
also consulted and they reviewed the situation with the POL management
team to provide their input. There was a change in the approach taken to

reviewing event errors related to cases being pursued by POL when this

31.

WITNO9710100
WITNO9710100

issue arose, and the manual process was introduced and continued to be
run to check event logs for potential problems. POL requested that Fujitsu
process the outstanding cases and complete the event analysis as soon as
possible. Both POL and Fujitsu staff worked together to agree on a workable

solution due to the sensitive nature of the problem.

Senior management from Fujitsu and POL were involved and kept up to date
with progress. Fujitsu senior management communicated with POL senior
management on the matter, and both were constructive to agree a solution.
I believe Fujitsu and POL senior management were concerned with ensuring
that the necessary checks were carried out on the ARQ data retrospectively
once the issue had been identified. In turn, they were concerned with getting
the change proposal approved so that the new changes could be

incorporated into HNGx code.

In relation to the resolution of the issue, the fix for the software issue relating
to the EOD process was delivered to the live estate in October 2008. The
issue of manually analysing event logs was replaced by introducing this
automatically into the application for the HNGx solution once the change
proposal was approved and the additional filtering was introduced in the
retrieval application. The tactical solution would have to continue during the
lifetime of the Legacy Horizon audit system. As can be seen from
FUJ00155476, the change proposal was finalised and approved on 31

March 2009.

My handover
32. The Inquiry has asked me to set out any handover or discussions of ongoing
work I recall having with Andy Dunks or others following my move to another
role. In doing so, I have reviewed FUJ00155498 and FUJ00155507 as
referenced in the Request. I recall speaking with Mr Dunks about him
continuing the meetings with Mr Simpson regarding incident management.
These meeting were mainly based on reviewing lost time on the counters.
There were no other handovers made and I retired after this in November

2009.

GENERAL
33. I There are no other matters that I would like to draw to the attention of the

Chair of the Inquiry.

Statement of Truth
