bringing in the admissibility of computer evidence

Commission into its 1999 ‘legal presumption of the
reliability of computer evidence’, without which the

‘Avoiding future PO Horizon-like miscarriages of
justice – the Expert way’, Feb 5, 2024 Expert Witness
Journal. By Dr Stephen Castell CITP MEWI
It took an ITV broadcast dramatization, Mr Bates vs.
the Post Office, for the PO Horizon affair to gain
enough public outrage to get the attention of the UK
government to do something, fast, to rectify the damage caused to many hundreds of PO Sub-Postmasters
and Postmistresses, and their families, arising from
private prosecutions brought by the Post Office, sustained over twenty years, 1999-2019, prosecutions that
wrongfully relied on the evidence of the faulty Horizon computer system – described as the ‘greatest ever
miscarriage of British justice’. The trials of those
falsely accused by the Post Office were conducted on
the legal presumption that computer-generated evidence should be treated as completely trustworthy,
unless the defence could explicitly prove that it was
faulty. This was the crucial, but wrong-headed, forensic foundation of the whole sorry 20-year PO Horizon
travesty of justice. But how did this happen? My 1980s
