A modern fable.
In 1999 the UK Post Office introduced a new computer system named Horizon into its network of post offices throughout the UK. The system managed the important tasks of transactions, accounting and stocktaking. Soon after it was introduced postmasters complained about bugs in the system which was reporting shortfalls, many amounting to thousands of pounds. Postmasters were discovering losses they could not explain. The Post Office took large numbers of postmasters to court where they were found guilty of theft, fraud and false accounting.
In court representatives of the Post Office testified that each case was unique; there was no evidence of widespread problems and on that basis the postmaster was always found guilty. Many former postmasters and postmistresses have described how the saga ruined their lives. They had to cope with the long-term impact of a criminal conviction and imprisonment, some at a time when they had been pregnant or had young children. Marriages broke down, and courts have heard how some families believe the stress led to health conditions, addiction and premature deaths.
In December 2019, the Post Office paid out £58 million to sub-postmasters who were awarded compensation for past false prosecutions of monetary theft that had been based on faulty evidence from the Horizon IT system. The judge presiding on the case, Mr Justice Fraser, described the Post Office’s approach to the case as “institutional obstinacy” that, “…amounted, in reality, to bare assertions and denials that ignore what has actually occurred, at least so far as the witnesses called before me in the Horizon Issues trial are concerned. It amounts to the 21st century equivalent of maintaining that the earth is flat.”
The CEO of the Post Office during this period was Paula Anne Vennells, CBE who just happens to be an ordained Anglican minister. Under her leadership, from 2012 to 2019 the Post Office prosecuted hundreds of subpostmasters for fraud, despite knowing that the financial discrepancies were actually arising from computer errors for which her own company was responsible. In 2019 she became chair of the Imperial College Healthcare NHS Trust in London. She also became a non-executive board member of the Cabinet Office.
On 19 March 2020, Vennells was harshly criticised in the House of Commons, particularly by Kevan Jones, MP for North Durham, who said, “Obviously, as a board member she knew what was going on, including the strategy in the court case and the bugs in the system. What happened? She got a CBE in the new year’s honours list for services to the Post Office. That is just rubbing salt into the wounds of these innocent people. There is a case for her having that honour removed, and I would like to know how she got it in the first place when the court case is ongoing. Added to that, she is now chair of Imperial College Healthcare NHS Trust. Again, I would like to know why and what due diligence was done on her as an individual… In December 2020 it was announced that she would be leaving these roles early, for personal reasons.”
Vennells subsequently 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.”
There were more than 700 prosecutions based on Horizon evidence. The commission and the Post Office are asking anyone else who believes their conviction to be unsafe to come forward. Those whose convictions have been quashed are Josephine Hamilton, Hughie Noel Thomas, Allison Henderson, Alison Hall, Gail Ward, Julian Wilson, Jacqueline McDonald, Tracy Felstead, Janet Skinner, Scott Darlington, Seema Misra, Della Robinson, Khayyam Ishaq, David Thomas Hedges, Peter Anthony Holmes, Rubina Shaheen, Damien Owen, Mohammed Rasul, Wendy Buffrey, Kashmir Gill, Barry Capon, Vijay Parekh, Lynette Hutchings, Dawn O’Connell, Carl Page, Lisa Brennan, William Graham, Siobhan Sayer, Pauline Thomson, Tim Burgess, Nicholas Clark, Margery Williams, Tahir Mahmood, Ian Warren, David Yates, Harjinder Butoy, Gillian Howard, David Blakey and Pamela Lock.
Following the convictions some of these former postmasters went to prison, were shunned by their communities and struggled to secure work. Some lost their homes and even failed to get insurance owing to their convictions. Three have since died. They always said the fault was in the computer system, which had been used to manage post offices’ finances since 1999.
The Post Office settled the civil claim brought by more than 550 claimants for £57.75m, without admitting liability, in December 2019. Opening the appellants’ case on Monday, Tim Moloney QC said: “Essentially the Post Office in the face of all the evidence was prepared to accept that subpostmasters of previous good character, who had hitherto run decent responsible profitable businesses, became criminals overnight. Alarm bells should have rung.” He added, “The Post Office “chose to disbelieve the subpostmasters … It chose to ignore the distress that was being suffered by those subpostmasters.”
