Nobody is questioning that the evidence contained in the body of the Hutton report appears to be accurately recorded. The complaint is that the judge's summary did not properly reflect the evidence. This is something that happens in court cases, sometimes.

Unfortunately, there wasn't a jury, in a position to weigh the summary against the evidence before giving a verdict; and there isn't an appeals procedure. Those are the two ways in which the legal system provides some protection against judges who do this kind of thing in criminal cases.
