Duranda Clarke was one of a group of former sub-postmasters and post-mistresses who were convicted of offences including theft, false accounting, and fraud, based on information from a computer system called Horizon which suggested that money had gone missing from post-office branch accounts. The basis of each of the prosecutions in these cases was that money missing from the branch account had been a result of theft by the sub-postmaster or mistress or had been covered up by fraud or false accounting by the sub-postmaster or mistress. However, the accounts of a branch post office did not in fact reflect missing cash or stock but was a result of a bug within the Horizon system which caused errors or defects.
An unexplained shortfall of more than £41,000 was found in Ms Clarke’s accounts. As a result she was prosecuted, and pleaded guilty to a count of fraud. She was sentenced to six months in prison, suspended for a year, and 150 hours of unpaid work.
Ms Clarke’s conviction was quashed based on evidence indicating that the Horizon computer system was faulty, and responsible for incorrectly flagging shortfalls in accounts.< Back to Case Search < Back to Overview Graph
