The story to date
Since April 2021 the appeal courts have overturned convictions in more than 80 Post Office Horizon cases.
These were convictions of former sub-postmasters, managers or counter assistants in Post Office branches, who had been convicted of, or who had pleaded guilty to offences including theft, fraud and false accounting.
In each of the cases the court decided that it had been unfair to prosecute the individual because there were serious defects in the Post Office’s Horizon computer system.
