Where evidence before a parole board came from a source who would be at risk were his identity disclosed to the prisoner, the board had an express authorisation, under the Parole Board Rules 2004 r.6(3), to withhold the sensitive evidence from the prisoner and his legal representatives. The board also had the power, through the specially appointed advocate procedure, to mitigate any unfairness to the prisoner caused by the withholding of such evidence.
