Post Office Cases – Challenging a Conviction

If you believe that you may have been wrongly convicted because of problems with the Horizon computer system, you can consider challenging your conviction.   

The CCRC can help if you pleaded guilty in a magistrates’ court or have already tried to appeal and been unsuccessful.

We have referred 62 Post Office Horizon cases to the appeal courts, with convictions in 56 of these being overturned. For further information on challenging Post Office convictions, read the CCRC’s guide here

I have nothing but praise for the work the CCRC did for me and my ex-colleagues. If you are in a similar situation where you know you have been wrongly convicted, I urge you to contact them.

The story to date

Since April 2021 the appeal courts have overturned convictions in more than 70 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.  

Court of Appeal judgements

Two key Court of Appeal judgements have been handed down in the Post Office Horizon cases. These are Robert Ambrose and Others v Post Office Ltd on October 7 2021 and Josephine Hamilton and Others v Post Office Ltd on 23 April 2021
