Fixing Horizon bugs would have been too costly, Post Office inquiry told

Asked about ‘missed opportunity’ to address problem, Fujitsu developer says focus was on replacing Horizon

A Fujitsu software developer who raised the issue of bugs in the Horizon IT system said the company did not properly fix the problem because it would have been too expensive and time-consuming, the inquiry into the Post Office scandal has heard.

Faults in Fujitsu’s Horizon IT system resulted in the Post Office wrongfully pursuing and prosecuting more than 900 post office operators for theft, fraud and false accounting in what has been called the most widespread miscarriage of justice in UK history.
