Post Office Horizon scandal: Legal and computer IT expert who can talk about if all evidence from Horizon being used to convict subpostmasters being unsafe
I am looking to speak with a legal expert with a specialism in computer systems or IT who can let me know if there's a possibility of all the Post Office cases which used evidence from the Horizon system to convict subpostmasters (or take their money) being treated retroactively as unsafe and therefore any legal ruling which used it is automatically thrown out.
I.e. We know the Horizon system was broken, so can a court or parliament say that any criminal or civil case which relied on evidence from it is automatically overturned en masse?
Thanks,
Oliver Price
