| The answer to this question is that senior executives within the Post Office knew that Horizon had faults and deliberately withheld the information when prosecuting the sub-postmasters. This is a fundamental breach of the prosecutor's duty to disclose any evidence that undermines the prosecution case or supports the defence case. This duty continues to exist after conviction so timing of knowledge is irrelevant. The judgment is telling in that there are records in which Post Office officials made statements that minutes of meetings about faults in the Horizon system should not be taken so as to avoid having to disclose them in proceedings. It is corporate failure on an unimaginable scale and three convicted individuals have died before having their convictions quashed. Yesterday's judgment is long but very readable. I would anticipate further fallout and understand there may be a live police investigation on the basis that several individuals may have perverted the course of justice by either proceeding with prosecutions or omitting material evidence from testimony. |
The OP asked, "doesn't there need to be evidence beyond just 'a computer said so'?".
You said the answer is that "the computer said so" and then the operator of the computer said "I agree with the computer".
In my mind, the question still remains. Isn't there any requirement to show where the money went, what account it went into, give dates and details about how they stole the money, etc?
Of course, hiding the known bugs in the software is a scandal and worth talking about, but it doesn't answer the original question I think.
