The '''British Post Office scandal''' or '''Horizon scandal''' involved faulty accounting software, provided by [[Company:Fujitsu|Fujitsu]] and known as Horizon, creating false shortfalls in the accounts of thousands of subpostmasters, leading to what prime minister Rishi Sunak has described as "one of the greatest miscarriages of justice in our nation's history". Between 1999 and 2015, over 900 subpostmasters were convicted of theft, fraud and false accounting, with about 700 of these prosecutions carried out by the Post Office. Other subpostmasters were prosecuted but not convicted, forced to cover Horizon shortfalls with their own money, or had their contracts terminated. The court cases, criminal convictions, imprisonments, loss of livelihoods and homes, debts and bankruptcies, took a heavy toll on the victims and their families, leading to stress, illness, divorce and, in at least four cases, suicide.

Although many subpostmasters had reported problems with the new software, the Post Office had insisted that Horizon was robust and failed to disclose its knowledge of faults in the system while securing convictions. 
In May 2009, ''Computer Weekly'' broke the story about problems with Horizon, and in September 2009 subpostmaster Alan Bates launched the Justice for Subpostmasters Alliance (JFSA). In 2012, following pressure from campaigners and a number of Members of Parliament, led by James Arbuthnot, the Post Office appointed forensic accountants from the firm Second Sight to conduct an investigation into Horizon. Second Sight concluded that Horizon contained faults that could result in accounting discrepancies, but the Post Office nevertheless insisted that there were no systemic problems with the software. 

In 2017, 555 subpostmasters led by Bates brought a group action in the High Court against the Post Office. After the judge ruled in 2019 that the subpostmasters' contracts with the Post Office were unfair and that Horizon contained bugs, errors and defects, the case was settled out of court for £58 million, which left the claimants with about £20,000 each after legal costs. The government later agreed to supplement their awards. The judge's rulings in the case paved the way for subpostmasters to challenge their convictions in the courts and led to the prime minister Boris Johnson's announcement in February 2020 that the government would establish an independent inquiry into the scandal. The Post Office Horizon IT Inquiry was set up later that year, and was converted into a statutory public inquiry in June 2021. 

Courts began to quash convictions from December 2020. By January 2024, nearly 100 of the subpostmasters' convictions had been overturned in court, and plans for a blanket exoneration were announced by the government. Those wrongfully convicted became eligible for compensation from the Post Office, as did more than 2,750 subpostmasters who had been affected by the scandal but had not received criminal convictions. By January 2024, the Post Office had paid out £153 million to claimants, with 64% of all those affected by the scandal having received full and final compensation.

A four-part television drama, ''Mr Bates vs the Post Office'', was broadcast on ITV in January 2024, after which the scandal became a major news story and political issue. The same month, Sunak announced that the government would introduce legislation to exonerate wrongly convicted subpostmasters. As of January 2024, most of those wrongly convicted are still waiting to have their convictions overturned, the public inquiry is ongoing, and the Metropolitan Police is investigating individuals from the Post Office and its software provider, Fujitsu.

The Horizon accounting system was developed by [[Company:International Computers Limited|ICL Pathway]], owned by the Japanese company [[Company:Fujitsu|Fujitsu]]. In 1999, the Post Office started to roll out the new software to its branches and sub-post offices, the latter managed by subpostmasters on a self-employed basis under contracts with the Post Office.

===Installation and roll-out===
Horizon is the outcome of the Pathway project, and a procurement process that commenced in August 1994,<ref name="Beer-11Oct22">{{Cite web |date=11 October 2022 |title=Phase 2, Day 1: Opening Statement by Jason Beer KC |url=https://www.postofficehorizoninquiry.org.uk/sites/default/files/2022-10/POH%2011%20October%202022.pdf |access-date=29 November 2023 |website=Post Office Horizon IT Inquiry |pages=53, 131}}</ref> and was announced by social security minister Peter Lilley at the 1995 Conservative Party conference.<ref name="Indie-1999-05-10">{{Cite web |last=Harrison |first=Michael |date=10 May 1999 |title=ICL stumbles on Pathway to hell |url=https://www.independent.co.uk/news/business/icl-stumbles-on-pathway-to-hell-1092947.html |access-date=29 November 2023 |website=The Independent}}</ref> The original goal was to computerise the payment of benefits at post offices, replacing Girocheques and paper benefit books with swipe cards.

A precursor of the Horizon system had been rolled out to 300 post offices in 1995. At least two subpostmasters using the system were accused of fraud, but protests that the accounting problems were a "glitch in the system" were ignored.<ref>{{cite web |last1=Syal |first1=Rajeev |title=Post Office suspected of more injustices over Horizon pilot scheme |url=https://www.theguardian.com/business/2024/jan/07/post-office-suspected-of-more-wrongful-prosecutions-of-operators-over-horizon |website=The Guardian |access-date=8 January 2024 |date=7 January 2024}}</ref> In 1999, the Post Office commenced the national roll-out of Horizon,<ref name=BBCexplain>{{Cite news |date=22 March 2022 |title=Post Office scandal: What the Horizon saga is all about |work=BBC News |url=https://www.bbc.com/news/business-56718036 |access-date=9 April 2022}}</ref> which reached 10,000 branches by August 2000,<ref>{{cite web |title=Horizon passes 10,000 milestone |url=http://www.icl.co.uk/news/press/august2000/09aug2000.htm |website=icl.co.uk |publisher=[[Company:International Computers Limited|International Computers Limited]] |access-date=2 May 2022 |archive-url=https://web.archive.org/web/20000817011813/http://www.icl.co.uk/news/press/august2000/09aug2000.htm |archive-date=17 August 2000}}<!-- https://web.archive.org/web/20000817011725/http://www.icl.co.uk/news/index.htm --></ref> and over 13,000 by 2001.<ref name="CW-Nov00" /> By 2013, Horizon was used by at least 11,500 branches and was processing some six million transactions every day.<ref name="bugfound">{{cite news |url=https://www.bbc.co.uk/news/uk-23233573 |title=Bug found in Post Office row computer system |date=8 July 2013 |access-date=29 March 2015 |work=BBC News |last=Prodger |first=Matt}}</ref> It cost over £1 billion to install and eventually affected 18,000 post offices throughout the UK.<ref name=Hansard>{{Cite web |title=Hansard House of Commons |url=https://hansard.parliament.uk/commons/2020-03-19/debates/03E48E18-4B5E-4A42-84C3-684E6B58495D/HorizonSettlementFutureGovernanceOfPostOfficeLtd}}</ref>

On 8 April 2021, after the software problems had caused a scandal, Post Office chief executive Nick Read announced that the Horizon system would be replaced by a new IT system that would be "more user-friendly, easier to adapt for new products and services, and cloud-based to ensure easy maintenance and ready interoperability with other systems", and presented a plan to share Post Office profits with postmasters.<ref name="ComputerWeekly.com 2021 x339">{{cite web | title=End of the road for Post Office IT system that destroyed lives | website=Computer Weekly | date=13 April 2021 | url=https://www.computerweekly.com/news/252499238/End-of-the-road-for-Post-Office-IT-system-that-destroyed-lives | access-date=18 January 2024}}</ref><ref name="Kleinman 2021 z497">{{cite web | last=Kleinman | first=Mark | title=Post Office chief Read delivers plan to share profits with postmasters | website=Sky News | date=11 April 2021 | url=https://news.sky.com/story/post-office-chief-read-delivers-plan-to-share-profits-with-postmasters-12272455? | access-date=18 January 2024}}</ref>

=== Problems with the software ===
Subpostmasters, who are self-employed and run branch post offices under contract to the Post Office,<ref name=":4"/> began to report balancing errors to the Post Office within weeks of the Horizon system being installed, via the helpline the subpostmasters were instructed to use. The Post Office denied the subpostmasters' reports of faults in the system, insisted that the subpostmasters make up any shortfall of money, and in many cases untruthfully denied that any other subpostmasters had reported problems.<ref name="Glass"/><ref name="cw31Jan" /> In 2000, there were six shortfall convictions that relied on Horizon data.

In around 2000, problems with the system were reported by Alan Bates, the subpostmaster at Craig-y-Don from March 1998 until November 2003.

In 2020, Vennells, who stood down from her Post Office role in 2019, said of the 2013 report that "it concluded, while it had not found evidence of system-wide problems with the Horizon software, there were specific areas where Post Office should consider its procedures and operational support for sub-postmasters".<ref name="vennells letter">{{cite web |last=Vennells |first=Paula |title=Letter from Paula Vennells on Post Office and Horizon |date=25 June 2020 |url=https://committees.parliament.uk/publications/1621/documents/15462/default/ |publisher=Business, Energy and Industrial Strategy Committee |website=UK Parliament |access-date=24 June 2021}}</ref> Ron Warmington of Second Sight had said in 2019 "if the Post Office Board had believed ... and acted on ... what Second Sight reported ... instead of being led by the nose by its own middle management and in-house and external legal advisors, huge amounts of money, and human suffering, would have been avoided".{{sfnp|Wallis|2021a|p=381}} In July 2013, Second Sight issued an interim report and the Post Office admitted that software defects with ''Horizon'' had indeed occurred, but said that nevertheless the system was robust.

The Post Office is not a typical private prosecutor. The Private Prosecutors' Association questioned whether the Post Office was conducting private prosecutions at all and was in fact a "publicly-owned entity and a public prosecutor" during the relevant period.

As the mediation process broke down, the subpostmasters began to consult and combine their efforts into legal action. The action taken against the Post Office took the form first of group litigation in the name of ''Bates and others'', a civil action in the High Court by some 555 people. There were six 'lead claimants', and 23 'common issues' were identified and agreed to enable the court to examine the 555 cases.

=== Magistrates' courts ===

Magistrates' courts are not courts of record. An [[Social:Appeal|appeal]] against a conviction in a magistrates' court is to the Crown Court by way of a rehearing, or by way of case stated (but only where the appeal raises a point of law) to a Divisional Court of the High Court. {{as of|2021|07}}, the number of convictions obtained by the Post Office, directly or via public prosecution in magistrates' courts, is unknown or unpublished. On 30 June 2021, the Post Office issued a statement setting out its position in respect  of convictions in the Magistrates' Courts.<ref>{{cite press release |title=Post Office Statement on Postmasters' appeals of historical convictions |url=https://www.mynewsdesk.com/uk/post-office/news/post-office-statement-on-postmasters-appeals-of-historical-convictions-430529 |via=Mynewsdesk |date=30 June 2021 |publisher=Post Office Ltd |access-date=13 July 2021}}</ref>

The Criminal Cases Review Commission (CCRC) has posthumously referred the convictions of two former Post Office workers to the Crown Court - the first such referral in its history. The commission has statutory powers to refer Crown Court cases to the Court of Appeal, but not from the magistrates' to the Crown Court.

Peter Huxham pleaded guilty to fraud by misrepresentation in 2010 at Torquay magistrates' court. He was sentenced to eight months’ imprisonment. He died in 2020 and his son applied to have his case reviewed by the CCRC in 2021.

Roderick Dundee pleaded guilty to false accounting at Cambridge magistrates' court in 2005 and was given a community punishment order of 240 hours. He applied to the CCRC in 2020 but died the following year. His daughter has pursued the application on his behalf.<ref>{{Cite web |date=2023-12-12 |last=Castro |first=Bianca |title=Criminal Cases Review Commission first in posthumous referral over Post Office convictions |url=https://www.lawgazette.co.uk/news/criminal-cases-review-commission-first-in-posthumous-referral-over-post-office-convictions/5118058.article |access-date=23 January 2024 |website=Law Gazette}}</ref>

In a further application, during the trial, that the trial be stopped, K. Hadrill, for Misra, said of the prosecution's expert witness, "He operates under a restriction because he is an employee of Fujitsu who are under contract to the Post Office and he can only comply with his contractual terms as best he can and there is no suggestion his integrity is anywhere at fault as to what he is permitted to do, bearing in mind this is a Post Office prosecution. I don't go behind that but it is not an independent prosecution at arm's reach from the loser company and Mr Jenkins, so we have to have concerns as to the quality of his evidence and the best he has done in regard to the restrictions he operates under." The application was again unsuccessful. The prosecution told the jury, "In a Post Office case it is a Post Office investigator who conducts the interview because of course they are familiar with Post Office procedures in a way a Police Officer would not necessarily be."<ref>{{cite journal |title=View of case transcript Regina v Seema Misra T20090070 |url=https://journals.sas.ac.uk/deeslr/article/view/2203/2138 |website=journals.sas.ac.uk |doi=10.14296/deeslr.v12i0.2203 |access-date=13 July 2021|doi-access=free }}</ref>

==== ''Post Office Ltd v Castleton'' – January 2006 ====
[[File:Post Office and shop on Quay Road, Bridlington (geograph 5830057).jpg|thumb|Castleton's post office]]
This was a civil case in which the Post Office sued Lee Castleton. The case was heard before judge Richard Havery in December 2006 and January 2007. The defendant represented himself and counterclaimed damages in the sum of £11,250 on the ground that the Post Office wrongfully determined the contract as a subpostmaster following his suspension. The judge found for the Post Office on the claim for £25,858.95. He found the deficiencies were real, the business was not properly managed and that Castleton was therefore in breach of his contract with the Post Office. "Moreover, the losses must have been caused by his own error or that of his assistants. The counterclaim was dismissed."<ref name="castleton">{{cite BAILII |litigants=Post Office Ltd v Castleton |link= |court=EWHC |division=QB |year=2007 |num=5 |para= |parallelcite= |date=22 January 2007 |courtname=auto}}</ref> Unable to afford the losses and the £321,000 in legal costs, Castleton declared himself bankrupt.<ref>{{cite news |last=Roper |first=Jac |title=The true hell of the Post Office Horizon scandal |url=https://www.conveniencestore.co.uk/your-stories/the-true-hell-of-the-post-office-horizon-scandal/602552.article |work=Convenience Store |date=4 March 2020 |publisher= William Reed Business Media |access-date=17 July 2021 |quote="At his case in the High Court in December 2005 and January 2006 the judge decided that, as Lee's contract had spelled out, he was responsible for any losses.

The Post Office knew Castleton would not be able to pay if he lost but that the state-owned company wanted to "show the world" it would defend the Horizon system. Lawyers for the Post Office opted not to tell a subpostmaster about thousands of issues raised about the Horizon IT system out of concern he would be 'swamped' by disclosure. Stephen Dilley, the solicitor for the Post Office in its civil claim against Lee Castleton, felt the request for disclosure by his opponent had seemed 'onerous'. He defended the decision not to disclose details of the 12,000-15,000 calls being made monthly by other subpostmasters reporting technical problems. The Post Office pursued him through a week-long trial which resulted in his bankruptcy. The Horizon inquiry heard that it had been estimated that it would take three to four weeks to go through the thousands of calls which would cost the Post Office up to £3,000. The organisation ended up spending £300,000 overall on the Castleton litigation. Counsel for the inquiry said the large number of calls was precisely the reason for investigating the Horizon system further and deciding what should be disclosed to Castleton about wider issues with it and suggested the question of relevance should have been left to Castleton and his representatives. The solicitor told the inquiry that counsel had advised him not to disclose an earlier auditor's report citing Horizon problems, he was also instructed by the Post Office not to disclose it. As the case continued he said, the motivation of the Post Office changed and what they wanted out of the case changed. It was less about making an example of Castleton and more about sending a message that they were willing to defend the Fujitsu Horizon system. Asked by counsel for the inquiry, 'Looking back, do you think the brinkmanship and the tactics were appropriate?' Dilley replied 'Yes.' Asked if he could and should have made wider disclosure, Dilley responded 'No'.<ref>{{Cite web |last=Hyde |first=John |date=22 September 2023 |title=Solicitor for Post Office defends failure to disclose Horizon helpline calls |url=https://www.lawgazette.co.uk/news/solicitor-for-post-office-defends-failure-to-disclose-horizon-helpline-calls/5117315.article |access-date=22 January 2024 |work=The Law Society Gazette}}</ref><ref>{{Cite news |last=Sweney |first=Mark |date=21 September 2023 |title=Post Office knew legal case was likely to bankrupt Horizon IT victim, lawyer says |url=https://www.theguardian.com/business/2023/sep/21/post-office-knew-legal-case-was-likely-to-bankrupt-horizon-it-victim-lawyer-says |access-date=22 January 2024 |work={{wipe|The Guardian}}}}</ref>

{{blockquote|The recusal application was issued the day after Mr Godeseth's cross-examination had made it clear, not only that this remote access existed, but after he was taken in careful cross-examination through specific examples of Fujitsu personnel manipulating branch accounts, and leading to discrepancies in branch accounts. I am aware that criticism of the Post Office and Fujitsu in this respect may prove to be controversial, as earlier criticism of certain aspects of the Post Office's case in Judgment (No. 3) was not well received by it. However, if criticism is justified, I consider it would be detrimental to proper resolution of the group litigation if that criticism were to be withheld simply because it might lead to a further negative reaction by the Post Office. It is also an inherent part of the judicial function in any litigation to make findings, which may include criticisms where justified, that may be contrary to a litigant's own view of the merits of their case. Some litigants are so convinced of the righteousness of their own position that they consistently refuse to accept any possible view of the litigation other than their own. Such a blinkered view is rarely helpful, and would be particularly unhelpful from a publicly owned institution.}}

Paula Vennells, the then-Post Office chief executive, in December 2019, after Post Office Ltd conceded the court cases, apologised to workers affected by the scandal, saying: "I am truly sorry we were unable to find both a solution and a resolution outside of litigation and for the distress this caused."{{sfnp|Wallis|2021a|page=382}} Her letter to the Energy and Industrial Strategy Select Committee says "The message that the Board and I were consistently given by Fujitsu, from the highest levels of the company, was that while, like any IT system, Horizon was not perfect and had a limited life-span, it was fundamentally sound" (Answer 11).<ref name="vennells letter"/> She said "I raised this question repeatedly, both internally and with Fujitsu, and was always given the same answer: that it was not possible for branch records to be altered remotely without the subpostmaster's knowledge.

The extent to which the government was aware of the Post Office's approach to its defence was questioned during the parliamentary debate on 19 March 2020. David Jones MP said, "Of course the Post Office has a non-executive director appointed by the Government. One must assume that that non-executive director is reporting to Ministers." Kevin Jones MP replied, "If I had been the Minister, I would have had that person in and scrutinised what was going on ... That would certainly have applied in the past few months, given the hundreds of millions of pounds that have been spent defending the indefensible." Bambos Charalambous MP said, "The Post Office seemed to have unlimited funds at its disposal to fight this action, ... The Post Office is an arm's length organisation, but there seems to be no accountability ..." Chi Onwurah MP said, "Its only shareholder is the Secretary of State for Business, Energy and Industrial Strategy, so more should have been done to address the scandal before it was allowed to fester to this extent."<ref name="hansard">{{Cite Hansard |house=House of Commons |title=Horizon Settlement: Future Governance of Post Office Ltd |url=https://hansard.parliament.uk/Commons/2020-03-19/debates/03E48E18-4B5E-4A42-84C3-684E6B58495D/HorizonSettlementFutureGovernanceOfPostOfficeLtd |date=19 March 2020 |volume=673 |column_start=1224 |column_end=1246 |access-date=15 July 2021}}</ref>

During the case, six separate judgments were handed down:<ref name="J3" />

===== Judgment No 1 Applications to alter timetable – November 2017 =====

Referring to costs and delay, the judge said, "Fitting hearings around their availability has all the disadvantages of doing an intricate jigsaw puzzle, with none of the fun associated with that activity."<ref name="J1">{{cite BAILII |litigants=Bates & Ors v Post Office Ltd |link= |court=EWHC |division=QB |year=2017 |num=2844 |para= |parallelcite=[2017] 4 WLR 221 |date=10 November 2017 |courtname=auto}}</ref>

===== Judgment No 2 Application to strike out evidence – October 2018 =====
This decision followed a case management hearing and dismissed an application to strike out roughly one-quarter of the lead claimants' evidence – more than 160 paragraphs. Mr Justice Fraser said "The application by the defendant to strike out this evidence appears to be an attempt to hollow out the Lead Claimants' case to the very barest of bones (to mix metaphors), if not beyond, and to keep evidence with which the defendant does not agree from being aired at all."<ref name="J2"/> The judge commented that adverse publicity for Post Office was not a matter of concern for the court if the evidence was relevant and admissible. He also warned against the aggressive conduct of litigation, particularly in a group action of this nature.<ref>{{cite web |last=Heppinstall |first=Adam |title=Strike out of parts of witness statements application dismissed in group litigation (Bates and others v Post Office) |url=https://3yf6pp3bqg8c3rycgf1gbn9w-wpengine.netdna-ssl.com/wp-content/uploads/2018/10/CA-826-Bates-v-Post-Office-Adam-Heppinstall.pdf |website=LexisNexis |access-date=1 July 2021 |date=18 October 2018 |archive-date=9 July 2021 |archive-url=https://web.archive.org/web/20210709182138/https://3yf6pp3bqg8c3rycgf1gbn9w-wpengine.netdna-ssl.com/wp-content/uploads/2018/10/CA-826-Bates-v-Post-Office-Adam-Heppinstall.pdf |url-status=dead }}</ref> The application was dismissed.

===== Judgment No 3 Common Issues – March 2019 =====

The subpostmasters and the Post Office had identified 23 issues relating to the contractual relationship between them and about which they disagreed. The judge made findings on each so that obligations under all iterations of the contracts would be settled, both retrospectively and prospectively.<ref name="Common Issues trial judgment: cheat">{{cite web |last=Wallis |first=Nick |title=Common Issues trial judgment: cheat sheet |url=https://www.postofficetrial.com/2019/04/common-issues-trial-judgment-cheat-sheet.html |website=Post Office Trial |access-date=1 July 2021}}</ref> Of the 23 issues, 16 were decided in the subpostmasters' favour. The parties agreed that broadly the claimants were more successful.<ref name="J5" />{{rp|33&34}} Issue 1 was later described by the judge as important.<ref name="J3" /> He found subpostmasters' contracts are relational contracts. "This means that the Post Office is not entitled to act in a way that would be considered commercially unacceptable by reasonable and honest people."<ref name="Common Issues trial judgment: cheat"/>

In court, Fraser criticised testimony given by Post Office witnesses. The judge said Angela van den Bogerd (Head of Partnerships, Post Office) "did not give me frank evidence, and sought to obfuscate matters, and mislead me."<ref>{{Cite web|url=https://www.bbc.co.uk/news/uk-wales-55181709|title=FAW appoints Post Office director who 'misled court' |date=3 December 2020|access-date=20 April 2021|work=BBC |first=Gwyn |last=Loader}}</ref> Fraser commented on the evidence given by Stephen Parker, Head of Post Office Application Support, Fujitsu:

{{blockquote|I do not consider that Mr Parker was interested in accuracy in any of his evidential exercises. ... I do not consider his evidence in his witness statements to have been remotely accurate, even though he stoutly maintained that it was.<ref>{{Cite web|url=https://www.postofficetrial.com/2020/06/fujitsu-tries-to-dodge-blame-bus.html |title=Fujitsu tries to dodge the blame bus |date=26 June 2020 |access-date=20 April 2021 |first=Nick |last=Wallis |website=Post Office Trial}}</ref><ref name="J6"/>{{rp|par. 495–498}}}}

Of the evidence of one Post Office witness, the judge said, "The Post Office appears, at least at times, to conduct itself as though it is answerable only to itself. The statement that it is prepared to preserve documents – as though that were a concession – and the obdurate to accept the relevance of plainly important documents, and to refuse to produce them, is extremely worrying."<ref name="J3"/>{{rp|523}} Fraser said in the Horizon Issues trial,<ref name="J6"/>{{rp|64.2}}

{{blockquote|the possibility of future (as opposed to current) criminal prosecutions, or the potentially criminal impact upon individual subpostmasters, did more than hover in the background to the Horizon Issues trial. Some claimants who gave evidence in this trial were expressly accused by the Post Office of criminal offences in cross-examination in this trial, something which had also occurred in the Common Issues trial.}}

When the judgment was delivered, the Post Office said it would appeal. On 23 May, the judge refused the Post Office permission to appeal and set out his reasons on 17 June.<ref name="J3refuse">{{cite web |last=Wallis |first=Nick |title=High Court refusal to let the Post Office appeal first trial judgment |url=https://www.postofficetrial.com/2019/07/high-court-refusal-to-let-post-office.html |website=Post Office Trial |access-date=8 July 2021}}</ref> The Post Office applied for permission to appeal that refusal. During the Horizon Issues evidence, just as the judge returned to court for the final afternoon, Joshua Rozenberg reported, "he was told that the Post Office had served an application for his recusal ... Counsel representing Post Office on the Horizon issues had apparently not seen it. He made no mention of it that morning".<ref name="ironman">{{cite news |last=Rozenberg |first=Joshua |title=Post Office plays hardball with ironman judge |url=https://www.lawgazette.co.uk/commentary-and-opinion/post-office-plays-hardball-with-ironman-judge/5069964.article |work=The Law Society Gazette |date=15 April 2019 |access-date=2 July 2021}}</ref>

===== Judgment No 4 Application for recusal – April 2019 =====
The Post Office brought in Lord Grabiner to make an application to Fraser that he recuse himself. Grabiner is widely described as a 'legal heavyweight'.<ref>{{cite news |title=Post Office fails to force trial judge to step down |url=https://www.ft.com/content/b3a3ef62-5ade-11e9-939a-341f5ada9d40 |newspaper=[[Social:Financial Times|Financial Times]] |date=9 April 2019 |access-date=3 July 2021 |last=Croft |first=Jane |url-access=subscription}}</ref><ref name="ironman" /><ref>{{cite web |title=The Lawyer Awards shortlist: Litigation Team of the Year |url=https://www.thelawyer.com/the-lawyer-awards-shortlist-litigation-team-of-the-year/ |website=The Lawyer |date=25 September 2020 |access-date=3 July 2021}}</ref> Statements supporting the recusal application alleged that paragraphs 22 to 25 of Judgment No 3 were findings, or observations that fell outside the scope of the Common Issues trial. Paragraph 24 of that judgment gave the clear impression that the judge has already formed a firm view on these matters that will prevent him from taking an impartial view when they are revisited at subsequent trials.<ref name="J4">{{cite BAILII |litigants=Bates & Ors v Post Office Ltd (No 4 Recusal Application) |link= |court=EWHC |division=QB |year=2019 |num=871 |para= |parallelcite= |date=9 April 2019 |courtname=auto}}</ref>{{rp|17,18}} The statement further alleged that the judgment contained critical invective directed at the Post Office and that parts harshly criticised the Post Office's witnesses on irrelevant matters. The subpostmasters argued that the Post Office was insufficiently specific and the judge required the Post Office to identify the relevant paragraphs of Judgment No 3. In response, the Post Office cited 110 paragraphs.<ref name="J4" />{{rp|116}}

The recusal application was dismissed on two grounds, no bias, and waiver due to delay by the Post Office.<ref name="RecusalLN"/> Lord Grabiner had been asked to explain the delay in making the application. He replied "It was made at board level within the client and it also involved the need for me to be got up to speed from a standing start. And I am not the only judicial figure or barrister that has looked at this with a view to reaching that conclusion. It has also been looked at by another very senior person before the decision was taken to make this application. The delay, such as it is, is very, very tiny".<ref name="J4" />{{rp|279}} This submission was rejected.<ref name="J4" />{{rp|280}} The judge decided the issue of [[Social:Waiver|waiver]] as a result of the delay in making the application for recusal.

{{blockquote|Even if I had found that there were grounds of apparent bias on the face of Judgment No. 3, I would not have recused myself. This is because of the fact that the Post Office waited until almost two weeks after it had received Judgment No. 3 before it did anything in respect of making an application to recuse.<ref name="J4" />{{rp|274}}}}

The recusal application was opposed by the subpostmasters<ref name="J4" />{{rp|24}} and dismissed by the judge.<ref name="J4" />{{rp|289}}

===== Judgment No 5 Common Issues costs – June 2019 =====
The issuing by the Post Office of the recusal application on 21 March 2019 caused significant disruption to the Horizon Issues trial which had started on 11 March 2019, and to the Group Litigation as a whole. The subpostmasters applied for the costs of that application; the Post Office sought that the judge reserve costs, in the following terms:<ref name="J5">{{cite BAILII |litigants=Bates & Ors v Post Office Ltd (No. 5: Common Issues Costs) |link= |court=EWHC |division=QB |year=2019 |num=1373 |para= |parallelcite= |date=7 June 2019 |courtname=auto}}</ref>

{{blockquote|the court can't be sure that things will happen in the future that will affect and alter its view about incidence of costs. It simply cannot do so. If it does so now, in my submission as a matter of principle, that would evidence a predetermination or would go towards suggesting the court has reached a view about matters as to how things are going to pan out in the future.}}

The judge was troubled by this submission. Inherent was a veiled or implied threat that the Post Office will say that the overall outcome of the litigation, or other future issues, has been decided. The Post Office was attempting to put the court ''in terrorem'' again. After asserting no predecision he said, "I do nonetheless consider that it is appropriate that I consider whether to make a costs order now ..." After considering cases cited, the application by the Post Office to reserve costs was dismissed. "The claimants would not be on an equal footing with the Post Office, a publicly funded body, if I reserved the costs of the Common Issues trial until the very end of the litigation ... I do not however consider that the presence of litigation funding should sway this decision one way or the other. I agree with Mr Cavender that the presence of such funding should not put a claimant in a better position ''vis-à-vis'' the correct stage in litigation at which costs should be addressed, compared to a non-funded party. However, regardless of who is funding litigation, a funder or an individual litigant, cash flow is a relevant consideration for most litigants. It is a consideration that might weigh less heavily upon publicly funded bodies such as the Post Office, but even such entities are likely to be concerned to some extent with cash flow."<ref name="J5"/> Of the subpostmasters' submissions that their award of costs should not be reduced, the court rejected them.<ref name="J4"/><ref name="J5"/>

===== Judgment No 6 Horizon issues – December 2019 =====
This judgment concerns the operation and functionality of the Horizon system itself. The hearings took place in March, April, June and July 2019. The hearings were interrupted by the Post Office's application for the judge to recuse, to appeal his refusal to recuse (judgment 4), and his judgment 3. The judgment was published in December 2019. Twenty-nine bugs, errors and defects were identified<ref name="bugs">{{cite web |title=Bates & Ors v the Post Office Ltd (No 6: Horizon Issues) [2019] EWHC 3408 (QB). Appendix 2.1 Summary of Bugs, Errors, Defects |url=https://www.judiciary.uk/wp-content/uploads/2019/12/bates-v-post-office-appendix-2-1.pdf |website=judiciary.uk |access-date=11 July 2021 |archive-date=11 July 2021 |archive-url=https://web.archive.org/web/20210711115019/https://www.judiciary.uk/wp-content/uploads/2019/12/bates-v-post-office-appendix-2-1.pdf |url-status=dead }}</ref> and analysed. Witnesses for the subpostmasters and for the Post Office submitted statements and gave oral evidence. Documents that had been submitted, and further documents, the submission of which had been resisted were, after argument and rulings, submitted. These included the 'Known Error Logs' and the 'PEAKs', a browser-based software incident and problem management system used by Fujitsu for the Post Office account. Permission, for two IT experts to be called, one for the claimants (Jason Coyne) and one for the Post Office (Robert Worden)<ref name="J6"/>{{rp|par.6}}

The important judgment was about whether the Horizon computer system worked and was "robust", which the Post Office said it was.  Again, the judge found overwhelmingly in favour of the subpostmasters and that the original version of Horizon was "not robust" and, as to the later version, "its robustness was questionable, and did not justify the confidence placed in it by the Post Office in terms of its accuracy."<ref>{{Citation |title=Bates & Ors v the Post Office Ltd (No 6: Horizon Issues) (Rev 1) [2019] EWHC 3408 (QB) |date=16 December 2019 |url=https://www.bailii.org/ew/cases/EWHC/QB/2019/3408.html |access-date=10 August 2023}} (para 936)</ref>

During this trial, the Post Office issued an application that the judge recuse himself. That led first to Fraser's Judgment No. 4, and then to an application for permission to appeal that judgment. The applications and the appeal failed but caused considerable delay.<ref name="J6"/>{{rp|par.5–7}}

=== Court of Appeal (civil) ===

==== Permission to appeal Judgment No 3 – November 2019 ====

Lord Justice Coulson refused permission to appeal judgment No 3 and handed down his written reasons on 22 November.<ref name="coulson2">{{cite web |title=Judgment on PTA |url=https://www.jfsa.org.uk/uploads/5/4/3/1/54312921/post_office_approved_judgment.pdf |via=Justice For Subpostmasters Alliance |access-date=3 July 2021 |date=22 November 2019}}</ref> Before dealing with the 26 grounds that formed the basis of the application the judge set out a number of reasons that he felt militated against granting the Post Office permission to appeal. In short, the judge said:
* The trial was long and complex – 6 weeks – 60 lever arch files – 20 witnesses of fact. The judgment is 320 pages and 1,122 paragraphs long. No judge will ever know more about this case generally, and the Common Issues specifically, than Fraser.
* The oral hearing of the permission-to-appeal application had demonstrated the danger that consideration of one issue opened up another, and another until the trial is re-fought. That is manifestly not in the interests of justice.
* Many of the Post Office's challenges are challenges to the findings of fact made by Fraser. Challenges to such findings of fact are not open to an appellant in the position of the Post Office. Fraser's conclusions of law were so entangled with his findings of fact that Coulson considered it neither just, nor practicable to endeavour to separate them out.
* The Post Office made sweeping statements of the judgment which were demonstrably wrong. The Post Office takes findings "either wholly out of context, misstated, or otherwise not correctly summarised".
* Fraser dealt comprehensively with why he refused permission to appeal in his separate judgment of 17 June 2019 which itself runs to 91 paragraphs, and Coulson said that he agreed with Fraser's detailed reasons for refusing the application to appeal.
* The Post Office's approach in this application was, as Fraser correctly labelled it "attritional". The most obvious example is the Post Office's anxiety to state what they do not like about a particular proposal from the subpostmasters or the consequential finding by Fraser, without providing any practical alternative. None of this engenders any confidence in the underlying merits or prospects of success of the Post Office's application for permission to appeal.
* There is no greater or wider right to permission to appeal just because this is group litigation; indeed, from the point of view of practical justice the opposite may well be the case. In any event, the subpostmasters' contract was no longer in use.
* This application is founded on the premise that the nation's most trusted brand was not obliged to treat their subpostmasters with good faith, and instead entitled to treat them in capricious or arbitrary ways which would not be unfamiliar to a mid-Victorian factory-owner (the Post Office's right to terminate contracts arbitrarily and the subpostmasters alleged strict liability to the Post Office for errors made by the Post Office's own computer system, being just two of many examples). Given the unique relationship that the Post Office has with its subpostmasters, that position was a startling starting point for any consideration of these grounds of appeal.<ref name="coulson2"/>

The application was refused.

==== Permission to appeal Judgment No 4 – May 2019 ====

Lord Justice Coulson refused the Post Office permission to appeal the refusal to recuse.<ref name="RecusalLN">{{cite web |last=Beaumont |first=Kate |title=Guideline case on recusal applications (Bates v Post Office Ltd) |url=https://3yf6pp3bqg8c3rycgf1gbn9w-wpengine.netdna-ssl.com/wp-content/uploads/2019/05/Guideline-case-on-recusal-applications-Bates-v-Post-Office-Ltd.pdf |website=LexisNexis |date=30 May 2019 |access-date=3 July 2021 |archive-date=9 July 2021 |archive-url=https://web.archive.org/web/20210709183051/https://3yf6pp3bqg8c3rycgf1gbn9w-wpengine.netdna-ssl.com/wp-content/uploads/2019/05/Guideline-case-on-recusal-applications-Bates-v-Post-Office-Ltd.pdf |url-status=dead }}</ref><ref name="Court of Appeal recusal decision">{{cite web |title=Court of Appeal recusal decision |url=https://www.postofficetrial.com/2019/05/court-of-appeal-recusal-decision.html |first=Nick |last=Wallis |website=Post Office Trial |access-date=3 July 2021}}</ref> Coulson said that the subpostmasters had submitted "that the strike-out application arose because the PO wished to adduce extensive factual evidence in their favour but objected to any evidence to the contrary from the SPMs [subpostmasters]. As they put it 'the Post Office wanted the case decided all one way'. There remains a distinct flavour of that approach within the recusal application."<ref name="Court of Appeal recusal decision" /> "The application by the defendant to strike out this evidence appears to be an attempt to hollow out the Lead Claimants' case to the very barest of bones (to mix metaphors), if not beyond, and to keep evidence with which the defendant does not agree from being aired at all." Counsel for the subpostmasters, in a written submission that was quoted and accepted by the judge, said the application "appears to be an attempt by Post Office to secure an advantage at the Common Issues Trial by selectively tailoring the evidence which the Court is to consider."<ref name="J2" />

Of the submission by Lord Grabiner, that he was not the only judicial figure or barrister who had looked at the decision to seek recusal, Coulson said at paragraph 48: "Such a comment, presumably made ''in terrorem'', should not have been made at least without proper explanation of its relevance."<ref name="Court of Appeal recusal decision" /> In her legal analysis of the case Kate Beaumont said, "Recusal applications are extremely serious. They are not a tactic to be strategically deployed by a losing party." She quotes Coulson as saying "Without making any finding, he stated that he at least understood the claimants' submission that the recusal application and the permission to appeal application were made in an attempt to de-rail the litigation as a whole."<ref name="RecusalLN" />

The application was refused.

=== Court of Appeal (criminal) ===

In December 2019, Mr Justice Fraser stated that he had concerns regarding the veracity of evidence given by Fujitsu employees to other courts about the known existence of bugs, errors and defects in the Horizon system.<ref name="DSC" /> In March 2020, the Criminal Cases Review Commission (CCRC) referred for appeal the convictions of 39 Post Office applicants. The commission said it would be referring all those cases which involve convictions for theft, fraud and false accounting, on the basis that each prosecution amounted to an abuse of process.<ref>{{cite web |url=https://ccrc.gov.uk/ccrc-to-refer-39-post-office-cases-on-abuse-of-process-argument/ | title=CCRC to refer 39 Post Office cases on abuse of process argument | date=26 March 2020 |access-date=7 June 2020 |website=Criminal Cases Review Commission}}</ref> In May 2020, the CCRC referred a further eight such convictions, bringing the total to 47.<ref name="DSC" /><ref>{{Cite web|url=http://ccrc.gov.uk/the-ccrc-refers-eight-more-post-office-cases-for-appeal-bringing-total-to-47-so-far/ | title=The CCRC refers eight more Post Office cases for appeal – bringing total to 47 so far | date=3 June 2020|access-date=7 June 2020 |website=Criminal Cases Review Commission}}</ref> In January 2021, the CCRC decided to refer a further four convictions, bringing the total to 51.<ref>{{cite web |url=https://ccrc.gov.uk/ccrc-refers-four-more-post-office-horizon-cases/ | title=CCRC refers four more Post Office Horizon cases |date=20 January 2021 |access-date=21 April 2021 |website=Criminal Cases Review Commission}}</ref> In May 2021, Helen Pitcher, chair of the commission, told MPs that the organisation was 'not adequately resourced' if 200 cases were to be brought forward for review.

In April 2021, after an appeal before three judges, Lord Justice Holroyde, Mr Justice Picken and Mrs Justice Farbey, thirty-nine of the convicted former postmasters had their convictions quashed,<ref name="EWCA Crim 577"/> with a further twenty-two cases still being investigated by the Criminal Cases Review Commission.<ref name="x27"/> The case was heard over four days in March 2021. The forty-two appellants were represented by seven teams of barristers; the Post Office representatives were led by Brian Altman QC.<ref name="EWCA Crim 577"/>

At the commencement of the case, three of the applicant subpostmasters were represented by Paul Marshall and Flora Page, his junior. In December 2020, Marshall and Page resigned from the case under threat from the court of contempt proceedings. That threat was lifted at a hearing in April 2021 before Lord Justice Fulford.<ref name="Fulford nocase">{{cite web |title=Page and Marshall in the clear |url=https://www.postofficetrial.com/2021/04/page-and-marshall-in-clear.html |first=Nick |last=Wallis |website=Post Office Trial |date=28 April 2021 |access-date=20 July 2021}}</ref>{{sfnp|Wallis|2021a|p=476}}<ref name=legalfutures/> It was Marshall and Page who led the charge on the critical second limb of the appeal, that it was an "affront to the public conscience for the appellants to face prosecution."<ref name="x258">{{cite web |title=Paul Marshall's 'resignation' letter to the Court of Appeal |url=https://www.postofficetrial.com/2020/12/paul-marshalls-resignation-letter-to.html |first=Nick |last=Wallis |website=Post Office Trial |access-date=20 July 2021}}</ref>{{sfnp|Wallis|2021a|p=444-445}}<ref name="Felstead">{{cite BAILII |litigants=Felstead & Ors v Post Office Ltd |link= |court=EWCA |division=Crim |year=2021 |num=25 |para= |parallelcite= |date=15 January 2021 |courtname=auto}}</ref>{{rp|17}}

Forty-two historical convictions of dishonesty were referred by the Criminal Cases Review Commission (CCRC) to the Court of Appeal. "The CCRC referred the cases because it considered that two cogent lines of argument in relation to abuse of process were available to each appellant: first, that the reliability of Horizon data was essential to the prosecution and conviction, and it was not possible for the trial process to be fair; and secondly, that it was an affront to the public conscience for the appellant to face criminal proceedings."<ref name="EWCA Crim 577"/> Each of the forty-two cases was considered individually. Of the forty-two, just two had previously appealed, unsuccessfully.

The Post Office accepted Fraser's findings of the unreliability of the Horizon systems and, in some cases, of inadequate investigation, and/or of insufficient disclosure. In these cases, the Post Office did not resist the appeal on Ground 1 but it would oppose Ground 2. The Post Office divided the appellants into three groups; A, 4 cases where it asserted that both categories 1 and 2 abuse of process applied, group B, 35 cases where category 1 applied, but not category 2, and group C, where neither category applied. The Post Office would not seek a retrial of any appellant whose appeal is allowed.

The Attorney General instructed counsel as advocate to the court, Marshall and Page were succeeded by L. Busch and S. Fowles, and the court addressed "the issue of whether an appellant whose appeal was not resisted by the Post Office on Ground 1 was entitled to argue Ground 2."<ref name="EWCA Crim 577"/>{{rp|79}} All counsel at the December hearing agreed that no appellant is entitled as of right to argue Ground 2. An earlier written submission to the contrary was not pursued. Busch and Fowles went on to argue that "... the court must act judicially. It would be wrong in principle for the court to permit the respondent (the Post Office) effectively to preclude argument on Ground 2 by its concession that Ground 1 is not opposed. ... The appellants have suffered very severely as a consequence of their prosecutions, and a finding in their favour on Ground 1 alone would not fully vindicate them. ... She (Busch) pointed out that there has been an important disclosure since the Commission referred the cases, and submitted that the public interest required consideration of the complete picture."<ref name="can we judgment"/><ref name="4 WLR 115"/>

For the other applicants, it was submitted all were concerned about delay; only three of the whole group had actively sought to argue Ground 2 ... appellants would be content to have their appeals allowed on Ground 1 alone ... however, appellants do contend that Ground 2 is made out in their cases ... if the court concluded that argument should be heard on Ground 2, they would wish their submissions on Ground 2 heard.<ref name="can we judgment">{{cite BAILII |litigants=Hamilton & Others v Post Office Ltd |link= |court=EWCA |division=Crim |year=2021 |num=21 |para= |parallelcite=[2021] 4 WLR 115, [2021] WLR(D) 66 |date=15 January 2021 |courtname=auto}}</ref><ref name="4 WLR 115">{{cite web |url=https://www.iclr.co.uk/document/2021000122/casereport_9509fd5f-9bfe-4c8c-b673-8f767eb5bc06/html |title=''Hamilton & Others v Post Office Ltd'' [2021] 4 WLR 115 |publisher=Incorporated Council of Law Reporting |url-access=subscription}}</ref>

The court ordered that, "... in the exercise of the court's discretion we would permit argument on Ground 2 by any appellant who wished to advance it. In the event, each appellant did wish to do so."<ref name="EWCA Crim 577"/> The court set out its reasoning and highlighted four factors of particular importance:<ref name="can we judgment"/><ref name="4 WLR 115"/>
# abuse of court process is an important matter to the parties and the public, notwithstanding that the appellants had not previously applied for leave to appeal.
# Ground 1 presupposes that there should be a prosecution. The public may legitimately feel ... that a finding in the appellant's favour on Ground 2 adds materially to a finding in his or her favour on Ground 1. ... If in fact an appellant should never have been prosecuted at all, ... the court should make that determination.
# We are ... satisfied that case management can avoid any risk of these appeals becoming an open-ended exercise in finding facts.
# Fourthly, we do not accept the submissions that consideration of Ground 2 will cause undue delay in the determination of these appeals.

At the April hearings, after considering the submissions of the subpostmasters and the Post Office, the court stated, "In those circumstances, we are satisfied that a fair trial was not possible in any of the 'Horizon cases' and that Ground 1 accordingly succeeds in each of those cases."<ref name="EWCA Crim 577"/>{{rp|126}} The court then set out its reasoning in respect of Ground 2. In short, the court decided that Ground 2 succeeds in each of the "Horizon cases".<ref name="EWCA Crim 577"/>{{rp|127–138 }}

==== ''Felstead & Others and Post Office Ltd'' – April 2021 ====
At paragraphs 79 and 80 of the substantive ''Hamilton'' judgment,<ref name="EWCA Crim 577"/> the court referred to a directions hearing on 18 November. That hearing led to further hearings in November, December, and January. The court addressed three issues:

* information from Brian Altman, counsel for Post Office, alleging potential contempt of court by Page, junior counsel for three appellants (all in group B), by improper disclosure of the 'Clarke advice';
* "the issue of whether an appellant whose appeal was not resisted by POL on Ground 1 was entitled to argue Ground 2;"<ref name="EWCA Crim 577"/>{{rp|79}}
* an application by journalist Nick Wallis for the release of the 'Clarke advice'. Wallis' application failed.

Altman's information to the court on 19 November led to hearings on 3 December 10 December and 15 January before the present court, and to Marshall and Page resigning from the case. On 3 December, Altman said, "I am confident that the court understands why we brought these matters to the court's attention. ... For the avoidance of any doubt, I should like to make clear that the Post Office has not made application for anyone's committal for contempt. ... We have sought to assist the court as we were invited to do," referring to signed undertakings, "... the court suggested that all legal representatives sign an express undertaking not to use disclosed material other than for the proper conduct of these proceedings." Lord Justice Holroyde interjected, "I thought you suggested that," and Altman replied, "Ultimately, my Lord, I think it was at the suggestion of the court but that is what has happened and that is what has been done."<ref name="auto">{{cite web |title=Transcript: Court of Appeal hearing 3 Dec 2020 |url=https://www.postofficetrial.com/2020_12_03_archive.html |first=Nick |last=Wallis |website=Post Office Trial |access-date=6 August 2021}}</ref>{{rp|137–141}}{{sfnp|Wallis|2021a|pp=430-436}}

The court issued a brief judgment. "... we direct that the question of whether any contempt proceedings are to be initiated against Mr Marshall and/or Miss Page and, if so, whether by the Post Office or by the Court of its own initiative, must be adjourned for consideration after the appeals have been concluded. ... we direct that all further hearings must be before a different constitution."<ref>{{cite BAILII |litigants=R v Felstead & Ors |link= |court=EWCA |division=Crim |year=2020 |num=1678 |para= |parallelcite= |date=3 December 2020 |courtname=auto}}</ref> On 15 January 2021, the court set out its reasons.<ref name="Felstead"/> It led to Marshall and Page facing the possibility of an action against them, either by the court or by the Post Office, for contempt of court.

Of the second, Nick Wallis said, "It makes for troubling reading."<ref name="x258"/> In April 2021, the matter came before Lord Justice Fulford, Mrs Justice Cutts and Mr Justice Saini when it was declared no further action to be taken.

===== The Clarke advice =====
The 'Clarke Advice' consists of two pieces of advice to the Post Office in 2013 by Simon Clarke, a barrister engaged by Cartwright King (CK), a solicitors' firm instructed by the Post Office in relation to the Post Office prosecutions. In the first advice, written in July 2013, Clarke reminded the Post Office of their obligations as a prosecutor regarding disclosure and of the duties of an expert witness and expressed a view that several trials had been misled as to the reliability of the Horizon system. He said that Fujitsu employee Gareth Jenkins, even though he was aware of bugs in the system, had given expert evidence to the court attesting to Horizon's accuracy.<ref name="EWCA Crim 577"/>{{rp|81-90}}<ref>{{Cite web |last1=Witherow |first1=Tom |last2=Taggart |first2=Emma |last3=Ledwith |first3=Mario |title=Revealed: the Fujitsu boss who said Horizon was 'like Fort Knox' |url=https://www.thetimes.co.uk/article/post-office-scandal-fujitsu-duncan-tait-horizon-fort-knox-rzmj0sl9c |website=The Times |date=22 January 2024 |access-date=24 January 2024}}</ref> This advice prompted Cartwright King carry out the "CK Sift Review", which was then reviewed by Altman for the Post Office.

It was concluded in 2014."<ref>{{cite web |title=Oral submission to support the application to receive the Clarke advice |url=https://www.postofficetrial.com/2020/12/oral-submission-to-support-application.html |first=Nick |last=Wallis |website=Post Office Trial |date=3 December 2020 |access-date=1 August 2021}}</ref>{{sfnp|Wallis|2021a|p=460}} The second piece of advice was written in August 2013, after Clarke became aware that the Post Office had given instructions to shred minutes of a conference call about Horizon bugs, and again reminded the Post Office of prosecution disclosure obligations.<ref name="EWCA Crim 577"/>{{rp|81-90}}

== Compensation ==
Eligibility for compensation depends on the circumstances of an individual's case. There are three main schemes, for groups of victims who had different experiences of the scandal.<ref>{{Cite news |date=11 January 2024 |title=How do the Post Office scandal compensation schemes work? |url=https://www.bbc.com/news/uk-67942935 |access-date=23 January 2024 |work=BBC News}}</ref><ref>{{Cite web |url=https://corporate.postoffice.co.uk/en/horizon-scandal-pages/post-office-compensation-schemes/|title=Compensation Schemes |access-date=23 January 2024 |website=Post Office}}</ref> As of 11 January 2024, approximately £153 million had been paid to over 2,700 claimants across these three schemes,<ref name=Compdata>{{Cite web |title=Post Office Horizon compensation data: January 2024 |url=https://www.gov.uk/government/publications/post-office-horizon-compensation-data-for-2024/post-office-horizon-compensation-data-january-2024 |access-date=23 January 2024 |website=GOV.UK}}</ref> with 64% of all those affected by the scandal having received full and final compensation.<ref>{{cite web|url=https://hansard.parliament.uk/commons/2024-01-10/debates/3DDD9684-C08D-4E5E-AF73-CF85839412AB/PostOfficeHorizonScandal|title=Post Office Horizon Scandal|date=10 January 2024|work=Hansard}}</ref> It is estimated that more than 4,000 people have been told they are eligible for compensation.<ref>{{Cite news |date=17 January 2024 |title=Post Office scandal: The ordinary lives devastated by a faulty IT system |url=https://www.bbc.com/news/business-67956962 |access-date=23 January 2024 |work=BBC News}}</ref>

The Horizon shortfall scheme, originally named the historic shortfall scheme, was established by the agreement between the Post Office and the 555 subpostmasters in ''Bates & Others v Post Office Ltd''. It was designed to compensate subpostmasters who had lost money due to shortfalls caused by Horizon, but had not taken part in the group action and had not been convicted. The scheme is administered by the Post Office.<ref>{{cite web |date=13 December 2023 |title=Post Office (Horizon System) Compensation Bill |url=https://researchbriefings.files.parliament.uk/documents/CBP-9910/CBP-9910.pdf |website=UK Parliament}}</ref> By 15 January 2024 the scheme had received 2,753 eligible claims and paid out £93 million to over 2,172 claimants.<ref name=Compdata/>

In December 2019, at about the time of the high court verdict in ''Bates & Others v Post Office'', the government decided this group could not apply for compensation through the historical shortfall scheme.<ref>{{cite web |last1=Partridge |first1=Johanna |title=Falsely convicted postal workers must be 'fully compensated', says committee |url=https://www.theguardian.com/business/2022/feb/17/falsely-convicted-postal-workers-must-be-fully-compensated-says-committee |work=The Guardian |date=17 February 2022}}</ref> The details of the settlement between the subpostmasters and the Post Office were not made public until August 2020. In February 2022, MPs from parliament’s Business, Energy and Industrial Strategy (BEIS) committee expressed concerns about the time taken to make settlements to former Post Office operators who were wrongfully convicted as a result of errors in the company’s computer accounting system and warned that compensation needed to be concluded urgently, as many of those affected by the long-running scandal are elderly, some having died while awaiting redress, while others remained at risk of losing their homes.<ref>{{cite web |last1=Wallis |first1=Nick |title=Bates v Post Office settlement agreement revealed |url=https://www.postofficetrial.com/2020/08/bates-v-post-office-settlement.html |access-date=22 February 2022 |website=Post Office Trial}}</ref>

In April 2021, Nick Read, Post Office chief executive, urged the government to provide funding for compensation, saying "The Post Office simply does not have the financial resources to provide meaningful compensation."<ref name="Read">{{cite web |url=https://www.postofficetrial.com/2021/04/nick-reads-speech-to-troops.html |title=Nick Read calls on government to compensate Subpostmasters |first=Nick |last=Wallis |date=13 April 2021 |website=Post Office Trial}}</ref> Shortly afterward, the government promised "fair and speedy" pay-outs for the 555 victims of the Horizon IT scandal who had been excluded from the Post Office's compensation scheme.<ref>{{cite news |last=Flinders |first=Karl |date=7 May 2021 |title=Minister promises 'fair and speedy' compensation for 555 subpostmasters who defeated Post Office |work=Computer Weekly |publisher=TechTarget |url=https://www.computerweekly.com/news/252500395/Minister-promises-fair-and-speedy-compensation-for-555-subpostmasters-who-defeated-Post-Office}}</ref>

In July 2021, the government announced that subpostmasters wrongly convicted of offences would get interim compensation of up to £100,000.<ref>{{cite news |title=Post Office scandal: Postmasters to get up to £100,000 |work=BBC News |date=22 July 2021 |url=https://www.bbc.co.uk/news/business-57928397 |access-date=22 July 2021}}</ref>

On 22 March 2022, a government scheme was launched to compensate the 555 subpostmasters at the same level of compensation as subpostmasters who had had their convictions overturned..<ref>{{Cite news |date=22 March 2022 |title=UK to fully compensate postmasters who exposed scandal |url=https://www.bbc.com/news/business-60832112 |access-date=22 March 2022 |work=BBC News}}</ref>

In December 2022, the Horizon Inquiry heard that postmasters made bankrupt after being wrongly prosecuted were receiving a fraction of what they were due. One applicant ran a successful postmaster business for 20 years before his life was ruined by a false conviction which led to his mental health deteriorating and his being unable to pay his mortgage. In another case, a victim’s award of £25,000 was reduced to £4,500 after deductions paid to the official receiver. It appears that the shortfall scheme takes no account of whether the root cause of the bankruptcy was or may have been generated by the Horizon software. Tim Moloney said "Compensation is intended to put the claimant in the position they would have been if they had not been adversely affected… many of the debts accrued by these people which led to bankruptcy were caused by the shortfalls [wrongly flagged up by Horizon]". The compensation award is then "swallowed up" by legal obligations to repay debts.<ref>{{Cite web |date=2022-12-09 |last=Hyde |first=John |title=Postmasters' compensation swallowed up by official receiver, inquiry hears |url=https://www.lawgazette.co.uk/news/postmasters-compensation-swallowed-up-by-official-receiver-inquiry-hears/5114559.article |access-date=23 January 2024 |website=Law Gazette}}</ref><ref>{{Cite web |title=8 December 2022 — Searchable transcripts of the Post Office Horizon IT Inquiry hearings documentation |url=https://postofficeinquiry.dracos.co.uk/compensation-issues-hearing/2022-12-08/#submissions-by-mr-moloney |access-date=23 January 2024 |website=postofficeinquiry.dracos.co.uk}}</ref>

In a written ministerial statement on 10 June 2020, Paul Scully, Minister for Small Business, Consumers and Labour Markets, announced the scope of the independent review into the Post Office Horizon IT system and trials.<ref>{{Cite web|url = https://www.parliament.uk/business/publications/written-questions-answers-statements/written-statement/Commons/2020-06-10/HCWS280/ |title=Business Update: Written statement |id=HCWS280 |date = 10 June 2020|access-date = 13 June 2020 |first=Paul |last=Scully |publisher=UK Parliament}}</ref> Of the review's terms of reference, Lord Arbuthnot said in the House of Lords chamber on 6 October, "Yet the Government are expressly excluding from the scope of their inquiry the Post Office Ltd prosecution function, the Horizon group damages settlement and the conduct of current or future litigation. ... why have the Government excluded these most important things?" The minister replied that the settlement agreed in December was full and final and therefore excluded from the scope of the inquiry ... the Post Office is not conducting any private prosecutions and has no plans to do so ... only the courts can decide on criminal matters, such as whether to overturn the postmasters' convictions, so it would not be appropriate for the inquiry to look at these questions, especially when the court process is still ongoing.<ref>{{Cite Hansard |house=House of Lords |title=Post Office: Horizon Accounting System |volume=806 |url=https://hansard.parliament.uk/lords/2020-10-06/debates/C9B6BE03-DA68-487E-B045-27AF5351604F/PostOfficeHorizonAccountingSystem |date=6 October 2020 |column_start=520 |column_end=523 |access-date=3 August 2021}}</ref>

The non-statutory inquiry, now titled ''The Post Office Horizon IT Inquiry'' by the government and led by Sir Wyn Williams, began work in autumn 2020 and issued a call for evidence on 1 December 2020. The first public hearing session took place on 15 January 2021.<ref>{{cite web |url=https://www.gov.uk/government/groups/the-post-office-horizon-it-inquiry|title=The Post Office Horizon IT Inquiry |date=1 December 2020 |access-date=20 April 2021 |website=gov.uk}}</ref> The Justice For subpostmasters Alliance (JFSA) refused to take part in the inquiry, described it as a whitewash and called for a full public inquiry.<ref>{{cite web |title=March 2021 – and why only a Statutory Inquiry will now do |url=https://www.jfsa.org.uk/march-2021.html |website=Justice for Postmasters Alliance |access-date=14 February 2022}}</ref>

Neil Hudgell, of solicitors for subpostmasters said, "Now Post Office officials must face criminal investigation for maliciously ruining lives by prosecuting innocent people in pursuit of profits," and called for the prime minister to convene a judge-led inquiry.<ref>{{cite web |title=Subpostmasters cleared of convictions |date=23 April 2021 |url=https://www.hudgellsolicitors.co.uk/news/post-office-horizon/subpostmasters-cleared-of-convictions-now-post-office-officials-must-face-criminal-investigation-for-maliciously-ruining-lives-by-prosecuting-innocent-people-in-pu/ |publisher=Hudgells Solicitors |access-date=24 April 2021}}</ref> After the subpostmasters' successful appeals on both grounds 1 and 2 abuse of process, in an article headed "Calls grow for SRA and police to investigate Post Office lawyers", Hudgell is quoted as saying the Post Office engaged in "legal gymnastics to seek to persuade the court away from finding a clear systematic abuse of process of the criminal law." In the same article, Richard Moorhead, professor of law and professional ethics at Exeter Law School, said "the SRA and BSB should investigate whether anyone should be held to account amid professional concerns about who was responsible for disclosure issues."<ref name="lg26Apr" /> Solicitors for subpostmasters wrote to the government (DBEIS) asking it to re-establish the inquiry on a statutory footing and to consult again on the terms of reference. "The department should be called as witnesses under oath, not have effective control of the inquiry," ... "The Post Office wrongly prosecuted so many upstanding pillars of the community and its owners want to mark (their) own homework – that is unconscionable."<ref>{{cite web |last1=Hyde |first1=John |title=News focus: Post Office Horizon scandal – Where weren't the lawyers? |url=https://www.lawgazette.co.uk/news-focus/news-focus-post-office-horizon-scandal-where-werent-the-lawyers/5108343.article |date=3 May 2021 |work=The Law Society Gazette |access-date=31 July 2021}}</ref>

On 19 May 2021, the government announced that an extended, statutory inquiry into the computer scandal would deliver its conclusions in autumn 2022. Witnesses could now be compelled to give evidence. Scully said he and Sir Wyn had agreed that the context of the events had changed after convictions were quashed and hundreds more were expected to follow. Boris Johnson said:<ref name="wyn statut">{{cite news |last=Peachey |first=Kevin |title=Post Office Horizon scandal inquiry extended after criticism |work=BBC News |date=19 May 2021 |url=https://www.bbc.co.uk/news/business-57173296 |access-date=15 July 2021}}</ref>

{{blockquote|We must stand with postmasters to get to the bottom of what went wrong in the Post Office Horizon IT dispute. I heard first-hand the irreparable impact it has had on their lives. That's why, in light of the recent Court of Appeal judgment, we're stepping up our independent inquiry by putting it on a statutory footing, so we can get the answers they deserve.}}

On 19 May 2021, Wyn Williams said that in the following weeks, the inquiry would produce a statement of approach and that, in September 2021, a further statement of approach would set out all relevant details.<ref name="wyn1">{{cite web |last=Williams |first=Wyn |title=Statement from the Chair |url=https://www.gov.uk/government/publications/post-office-horizon-it-inquiry-2020/statement-from-the-chair-19-may-2021 |date=19 May 2021 |website=gov.uk |access-date=25 July 2021 |publisher=Department for Business, Energy & Industrial Strategy}}</ref>

On 28 July, the government (DBEIS) issued its fourth statement of approach, which included the inquiry terms of reference. After setting out preliminary and organisational matters – the appointment of solicitors and counsel to the inquiry – establishment of a website and of premises, etc., the statement set out terms of reference, in essence:

:A: Understand and acknowledge what went wrong and key lessons that must be learned.
:B: Obtain all available relevant evidence from the Post Office, Fujitsu, BEIS and UKGI to establish the failings of Horizon and the Post Office's use of information from Horizon.
:C: Assess whether the Post Office has learned and has delivered or made good progress on the changes necessary.
:D: Assess whether the commitments made by Post Office Ltd have been properly delivered.
:E: Assess whether processes and information provided by the Post Office to postmasters are sufficient.
:F: Examine the historical and current governance and whistleblowing controls are now sufficient to ensure that these failures do not happen again.

{{blockquote|"The Inquiry will consider only those matters set out in the preceding sections A-F. The Inquiry will not consider any issue which is outside the scope of the powers conferred upon the Inquiry by the Inquiries Act 2005. The Horizon group damages settlement (albeit the Inquiry may examine the events leading to the settlement), and/or the engagement or findings of any other supervisory or complaints mechanisms, including in the public sector, are outside the Inquiry's scope."<ref name="Inquiry"/>}}

During the non-statutory inquiry, two public hearings were held in early 2021.

Immediately after the November hearing, Williams said he would ask Post Office Limited, IT supplier Fujitsu, the Department for Business, Energy & Industrial Strategy and the UK government to waive privilege in respect of material relevant to the inquiry's terms of reference, and he set a deadline for response.<ref>{{cite web |last1=Hyde |first1=John |title=Post Office inquiry chair seeks waiver on legal privilege|url=https://www.lawgazette.co.uk/news/post-office-inquiry-chair-seeks-waiver-on-legal-privilege/5110466.article |website=The Law Society Gazette |publisher=The Law Society |access-date=9 November 2021}}</ref> On 16 November, Wyn Williams reported that all four parties had responded within the timescale specified and added "The response of POL, on any view, goes a very long way towards meeting the request I made of them. It is clear to me that in respect of many of the most crucial lines of investigation for the Inquiry POL has waived legal professional privilege."<ref>{{cite web |title=Post Office: Horizon Scandal – Sir Wyn Williams Inquiry – Confirmations of Waiver of Legal Privilege |url=https://cwue5.org/2021/11/17/post-office-horizon-scandal-sir-wyn-williams-inquiry-confirmations-of-waiver-of-legal-privilege/ |website=CWU Eastern No5 Branch CWU Eastern No5 Branch |date=17 November 2021 |access-date=22 February 2022}}</ref> The Post Office published its response to the request on 15 November 2021.<ref>{{cite web |title=Response on Behalf of Post Office Limited – Legal Professional Privilege |url=https://www.postofficehorizoninquiry.org.uk/sites/default/files/2021-11/Post%20Office%20Limited%20-%20response%20to%20Inquiry%20re%20privilege%20waiver.pdf |website=Post Office Horizon Inquiry |access-date=15 November 2021}}</ref> Government (BEIS) said that it was its "firm position that the inquiry should not be obstructed by the assertion of legal privilege", but the government-owned Post Office was more cautious. It agreed to a limited waiver over relevant material but would maintain privilege over documents relevant to ongoing litigation/remediation activities. The Post Office maintained privilege over documents relevant to the ongoing group litigation claim in the Employment Tribunal. It maintained privilege over legal advice related to the Historical Shortfall Scheme and to current and anticipated claims from individuals whose criminal convictions have been or will be quashed. This could have wide-reaching ramifications for the inquiry; if advice is withheld on the basis that it is relevant to current and anticipated claims from those who have had their convictions quashed, this may lead to gaps in the inquiry.<ref>{{cite web |last1=Wahnon |first1=Elisa |title=When can lawyers keep documents confidential on legal professional privilege grounds? |url=https://www.stewartslaw.com/news/when-can-lawyers-keep-documents-confidential-on-legal-professional-privilege-grounds/ |website=Stewerts |access-date=21 December 2021}}</ref>

On 13 February 2022, in a report prior to the start of the Wyn Williams hearings, the BBC quoted a prosecuted, jailed and subsequently cleared subpostmaster: "I want someone else to be charged and jailed like I was." This request was later repeated by several other subpostmasters.<ref>{{cite web |title=Wrongly convicted Post Office workers say former bosses should face jail |url=https://bmmagazine.co.uk/news/wrongly-convicted-post-office-workers-say-former-bosses-should-face-jail/ |website=Business Matters |date=16 February 2022 |access-date=16 February 2022}}</ref><ref>{{cite web |last1=Wearn |first1=Rebecca |last2=Smith |first2=Colletta |title=Post Office scandal: 'I want someone else to be charged and jailed like I was' |url=https://www.bbc.co.uk/news/business-60335109 |website=BBC News |date=12 February 2022}}</ref><ref>{{cite news |last1=Partridge |first1=Joanna |title=Wrongly convicted Post Office workers want ex-bosses jailed |work=The Guardian |date=16 February 2022}}</ref>

== Call for reform on digital evidence ==
In May 2021, the [[Organization:British Computer Society|British Computer Society]], a professional body for those working in IT in the UK, called for reconsideration of courts' default presumption that computer data is correct.<ref>{{Cite web|url=https://www.computerweekly.com/news/252501510/BCS-demands-reform-to-rules-on-computer-evidence-following-Post-Office-Horizon-scandal-revelations |title=BCS demands reform to rules on computer evidence following Post Office Horizon scandal revelations |work=Computer Weekly |publisher=TechTarget |first=Karl |last=Flinders |date=28 May 2021}}</ref><ref>{{Cite web|url=https://www.ukauthority.com/articles/bcs-calls-for-change-in-law-on-computer-evidence/|title = BCS calls for change in law on computer evidence |date=28 May 2021 |first=Mark |last=Say |work=UKAuthority |publisher=Informed Communications}}</ref>

The presumption that computer evidence is correct is based on a naïve and simplistic understanding of software systems. Large systems are complex and lay people cannot discern whether these systems are reliable or be confident that they can spot errors as they happen. It is difficult even for experts to judge the reliability of systems or detect any but the simplest errors.<ref name="DEESLR-PMarshall01">{{cite journal |title=The harm that judges do – misunderstanding computer evidence: Mr Castleton's story, 'an affront to the public conscience'|url=https://journals.sas.ac.uk/deeslr/article/view/5172|journal=Digital Evidence and Electronic Signature Law Review |volume=17 |pages=25–48|access-date=5 August 2022|date=14 March 2020|last=Marshall|first=Paul|doi=10.14296/deeslr.v17i0.5172 |s2cid=226025305 |doi-access=free}}</ref>
