Prison – Conditions. Prison Service Instruction (PSI) 22/2015, which provided that the discretion not to follow the Parole Board's recommendation to transfer the prisoner to open conditions should be exercised within very limited parameters, was lawful. The Administrative Court, in dismissing the claimant serving prisoner's application for judicial review, further held that the process by which the defendant Secretary of State's decision not to implement the recommendation of the Parole Board that the claimant be transferred to open conditions, had been reached had not been unfair.
