Powell v Chief Constable of North Wales Constabulary: CA 16 Dec 1999

Roch LJ said: ‘When an issue of public interest immunity is raised, the court’s first duty is to weigh the public interest in preserving the immunity against the public interest that all relevant information which might assist a court to ascertain facts relevant to an issue upon which the court is required to adjudicate should be before the court. See the passage from the speech of Lord Diplock in D v. NSPCC cited in Schiemann’s LJ’s judgment. Clearly the second public interest will be stronger in criminal cases than in civil cases because, normally, what will be at stake in criminal cases, namely the good name and liberty of the accused, will be weightier than what will be at stake in civil proceedings. No doubt there will be cases where, in order to carry out this balancing exercise, the judge will have to have disclosed to him the information for which the immunity is sought . . Once the balance comes down in favour of preserving the immunity from disclosure, then the court has no further discretion. Once that point is reached, it becomes a rule of law that the material or information must be excluded from the case, see Marks v. Beyfus and the passages from that case cited by Schiemann LJ.’
