Update law on computer evidence to avoid Horizon repeat, ministers urged

Critics say assumption in English and Welsh law that computers are ‘reliable’ reverses usual burden of proof in criminal cases

Ministers need to “immediately” update the law to acknowledge that computers are fallible or risk a repeat of the Horizon scandal, legal experts say.

In English and Welsh law, computers are assumed to be “reliable” unless proven otherwise. But critics of this approach say this reverses the burden of proof normally applied in criminal cases.
