Opinion
Re: Post Office Counters Ltd. -v- Mrs Julie Wolstenholme: Claim Number CR101947
I have been contacted by Weightman Vizards a law firm representing ‘ Post Office Counters
LTD’ and Mrs Julie Wolstenholme, an individual, and requested to make initial observations
that would be of value to the court in the matter of “Post Office Counters Ltd -v- Mrs Julie
Wolstenholme” in the Blackpool County Court, Claim number CR101947.
My initial opinion, prior to examination of call logs provided, was that it would be difficult to
establish if the level and type of support calls made by Mrs Wolstenholme were ‘reasonable’ or
otherwise without having access to levels and type of support calls made by a comparable post
office branch. It was explained to me that this direct comparison was not possible, due to such
logs not being available and as a consequence I have been instructed to conduct a more
detailed review of the material already available.
In light of the above I do not consider that I am required at this stage to produce a full expert
witness report as such, and have therefore set out my initial opinions in the format below.
This more detailed examination focused on the following documents provided to me:-
Claim form dated 19 April 2001 and amended Particulars of Claim dated 17 February 2003.
Amended Defence and Counterclaim dated 14 April 2003
Reply and Defence to Counterclaim
Order dated 6 October 2003
Claimant's List of Documents
Defendant's List of Documents
Claimant's witness statement
Defendant's witness statement
Additional set of call logs disclosed by the Claimant to the Defendant.
My observations considering the documents are as follows:
The statement from Ms Elaine Tagg, the retail network manager of the Post Office Ltd, at para
11 stated that:
“Mrs Wolstenholme persisted in telephoning the Horizon System Help Desk in relation to
any problems which she had with the system generally, these problems related to the
use and general operation of the system and were not technical problems relating to
the system.”
This, in my opinion is not a true representation on the evidence that I have had access to. Of
the 90 or so fault logs that I have reviewed, 63 of these are without doubt system related
failures. Only 13 could be considered as Mrs Wolstenholme calling the wrong support help desk
requesting answers to “How do I ..?” type training questions.
The majority of the system issues were screen locks, freezes, and blue screen errors which are
clearly not a fault of Mrs Wolstenholme’s making, but most probably due to faulty computer
hardware software, interfaces or power. In fact, on a detailed view of call 11021413, dated 2
November 2000, Ms Tagg may have witnessed first hand the style of system problems that
Mrs Wolstenholme experienced in her operation of the system. This fault log notes that:
“Elaine reports that one of the counters has a blue screen with the message STOP 0x000000a”
and was advised by the operator to “reboot”.
Although not uncommon in my experience of support helpdesk’s, I find it disconcerting that
the helpdesk’s first line support consistently advised Mrs Wolstenholme to “reboot” the system
(ie. switch the equipment off and back on again), without trying to understand the cause of the
error. It can be noted that a re-boot was advised in 47 out of the 63 occasions where system
errors were logged. This instruction treats the effect and not the cause, leaving the actual fault
which caused the error intact, and with it a recurrence seems inevitable.

Opinion
The types of faults, as reported in the faults logs were:-
“System Freezing” which is most probably due to either the hardware or interfaces crashing; or
alternatively fully saturated communication lines.
“System Halts displaying...” or “Blue Screen” which are almost certainly hardware faults.
It seems that each time that the system halted, the screen would display an error code. From
this error code, it would have been possible for the helpdesk operatives to establish the detail
of these hardware faults. However, it seems that this type of analysis was not undertaken by
the helpdesk with a simple re-boot being the preferred method of dealing with the issue.
That said, on a number of occasions, certain elements of counter equipment were indeed
exchanged but without any real improvement in the situation until around the end of June
2000.
The number of fault logs reduces after the end of June 2000, this could be due to the system
faults reducing in frequency i.e. being fixed, or simply that Mrs Wolstenholme tired of the
support department telling her to reboot the system (an activity which she could do herself). I
have no information to form an opinion either way.
It is interesting and certainly warrants further examination that in November 2000 the ‘system
freezing’ is reported again with the support operator stating: “They all freeze, but if it gets bad
give us a call and we will investigate” [11084054 dated 8 November 2000]
From the 31° of October (starting at call log number 10253234) there seems to be a number
of logs which talk of ‘large discrepancies’ in stock figures, trial balances with “all sorts of
figures showing minus figures” [Call Log 10311359].
Referenced in call log 11012223 there is a comment noted by the support operative that the
“pm advised that this is an intermittent problem occurring since the counters were upgraded
on 23.10”. Although the documents do not list an upgrade taking place, it does seem that
these “large” reported discrepancies occur very frequently and shortly after this noted
upgrade. Again this should be investigated further as another six system errors were noted in
November which seem to be a resurgence of the earlier, pre-July type errors.

Opinion
In Summary:
From a computer system installation perspective it is my opinion that the technology installed
at the Cleveleys sub-post office was clearly defective in elements of its hardware, software or
interfaces. The majority of the errors as noted in the fault logs could not be attributed to being
of Mrs Wolstenholme’s making or operation of the system.
The helpdesk operated by the Post Office would seem to be more focused on ‘closing calls’
than attempting to get to the bottom of the continual recurrence. The instruction to ‘re-boot’
would allow a call to be closed as the postmaster could continue to work once the system had
powered back up.
Without further examination, it is unclear whether the reduction of calls logged between July
and late October 2000 is attributable to a period of comparative system stability or merely
user disillusionment with the helpdesk. What is more clear is that from late October
recurrences of faults, which had been the subject of earlier logged calls, are reported once
again along with worrying ‘discrepancies’ in audits. This may, or may not be to do with an
‘upgrade’ of the counters which seems to have occurred on or around the 23 November 2000,
or may simply be an unconnected recurrence of the earlier faults.
