Bates v Post Office — High Court judgment on Horizon unreliability

Mr Justice Fraser's High Court judgment in Bates & Others v Post Office finds the Post Office Horizon IT system unreliable. The technical-evidence turning point in the Horizon scandal. Subsequent Court of Appeal quashings of hundreds of sub-postmaster convictions follow from December 2020 onwards. Mass statutory exoneration follows in 2024. The structural template for how collectively-resourced independent technical expertise enables appellate-level correction of mass-miscarriage convictions.
