An email to members of the Communication Workers Union (CWU) branch

representing postmasters, seen by Computer Weekly, was sent to advise them

what to look out for regarding the alleged fault, which incorrectly duplicates

payments.

This is a small but potentially NETAPP NAMED A LEADER IN THE

significant development in a dispute SARTNER 2016 MAGIC QUADRANT
FOR SOLID-STATE ARR

over the Horizon system that has

been running for years. The finding,

if proved, could call into question

Post Office claims that Horizon has

no systemic flaws.

Post Offices use an IT system Wi NetApp
developed by ICL/Fujitsu Services,

called Horizon, for their accounts. In 2009 Computer Weekly first revealed the
stories of subpostmasters who had received heavy fines and even jail terms for
alleged false accounting ~ which they blamed on the Horizon accounting system.
The Post Office has vehemently denied this claim. (See timeline below for more
on the dispute).

The alleged problem investigated by the CWU involves the process where

subposimasters transfer money from a core Post Office branch to a remote
branch created to serve rural areas, Known as an outreach, which is basi

branch on a laptop. These processes are known as remittances.

According to the CWU, branch payments can in certain circumstances be
duplicated ~ in effect creating a record of money that does not exist, recorded by
the system as being in the outreach branch. It would be the subpostmaster’s
responsibility to make up this sum unless the duplicated payments are removed.

The CWU said that, in a case documented by investigators, a core branch
transferred cash to an outreach branch and Horizon reduced the accounts of the
core by the amount transferred. The outreach transferred in the amount sent and
Horizon accepted the correct amount.

But Horizon did this four times, causing a foss of three times the actual amount

sent. The discrepancy was for money that did not exist.

“We have evidence that Horizon has duplicated the accepting in of a remittance
{on at least three occasions). This is despite the [payment’s] barcode having only
been scanned in once,” said the CWU email.

The Post Office helpline - the Network Business Support Centre ~ and the IT
helpline were contacted, but neither was able to help the postmaster, said the
CWU.

JA Post Office department recognises duplication
problem

Following a post on a web forum, another postmaster recognised the problem as
something she had experienced in the past, and the financial department of the
Post Office in Chesterfield was contacted on her advice.

According to the postmasters’ branch of the CWU, the financial department
recognised the issue and told the postmaster they would need to send 4 positive
monetary change to the Horizon branch accounts to negate the non-existent loss

that had been created by the duplication
The alleged fault, if proved, would question the Post Office's continued claims that

there are no systemic faults in Horizon.

The Post Office denies system-wide problems with Horizon and stressed that no
technical fault has been found to have been responsibie for a postmaster being
“wrongly held responsible for a loss”.

“[We have] robust back-office reconciliation processes to identify and address
account balancing issues when they arise,” said the Post Office.

“The Post Office provides extensive support, including visits to branches, if
posimasters need support about branch accounting or other aspects of running
their branch, and we encourage them to contact us if they have any concerns,” it
added.

“it rernains the case that more than three years of investigations have not
identified any transaction caused by a technical fault in Horizon which resulted in
a postmaster wrongly being held responsible for a loss.”

Mark Baker, secretary of the CWU postmasters branch, said: “If we get
complaints we have people with the skills to investigate the Horizon system on
behalf of subpostrnasters. In the process of doing this recently, we believe we
have found another systemic flaw.”

While the Post Office has said that occasional problems occur, it stresses there
are no systemic glitches.

There have however been claims of alleged probiems in the past by experts, but
the Post Office has always denied they represent evidence of systemic flaws.

‘The results of an independent investigation, commissioned by the Post Office and
carried out by forensic investigation company Second Sight, were published in
April 2015. The report said there can be systemic problems for users: “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.”

When Computer Weekly put the clairns to the Department for Business.
Innovation and Skills (BIS) at the time of the report, the BIS press office said:
“Systemic flaws would refer to errors or faults in the Horizon system capable of
causing the accounting discrepancies that have been alleged

“Rather, the sentence summarises the conclusions Second Sight reached, based
on their findings having looked at not only the Horizon system but other directly
and indirectly associated elements, such as training and support processes, and
individual subpostmasters' circumstances.”

Campaigners want an independent inquiry. “The only way we will get to the
bottom of it is to have a truly independent inquiry, which Post Office is not

involved in.” said one.

The Criminal Courts Review Commission (CCRC) is currently reviewing
subpostmasters’ claims of wrongful prosecution.

The CCRC has set up a team te focus on the cases including subpostmasters that
raceived suspended or non-custodial sentences, including community service, but
others that received custodial sentences for between six and 18 months.
