As the recent Post Office Horizon saga has demonstrated, there is a need to strike a considered balance between blind faith in technology and a lack of faith in IT. On Friday 23 April 2021, the Court of Appeal quashed the convictions of 39 former Post Office sub-postmasters for false accounting, fraud and theft with a further 700 overturned convictions potentially on the way after campaigners won a legal battle to prove the Post Office IT was at fault and the computer system on which their convictions were based was flawed. Described as one of the biggest miscarriages of justice in UK history, the judgment marked the culmination of a 20-year battle for justice for individuals whose convictions were based on incorrect information from the Post Office’s Horizon sales and accounting system, developed by Japanese IT company Fujitsu.
