New documents reveal that the Post Office was aware of over 100 bugs in a software system as early as January 1997, yet continued to prosecute sub-postmasters based on alleged losses caused by these bugs. These prosecutions included forcing sub-postmasters to pay for the alleged losses, resulting in job losses and criminal charges. Additionally, a top Post Office lawyer has been accused of misleading the Horizon IT inquiry about his knowledge of these software issues, which could have prevented the wrongful prosecutions.
