The powers that be will never admit it Rob.
Which is the issue.
The "powers that be" don't have to admit they were wrong. The CCRC are independent of the the police, the CPS and the government, as is the Court of Appeal.
If the 1,000+ page dossier really is fully of lots of "inarguable" grounds like the Campaign Team claim it is, there is no reason for the CCRC not to refer.
The CCRC would look very silly if they lost at a Judicial Review!
