The House considered a claim for public interest immunity.
Held: Lord Simon of Glaisdale said: ‘the public interest which demands that the evidence be withheld has to be weighed against the public interest in the administration of justice that courts should have the fullest possible access to all relevant material . . but once the former public interest is held to outweigh the latter, the evidence cannot in any circumstances be admitted. It is not a privilege which may be waived . . by the Crown . . or by anybody else’. It refers to the rule that certain evidence is inadmissible on the ground that to adduce it would be contrary to the public interest.
Lord Reid said: ‘There is no question of any privilege in the ordinary sense of the word. The real question is whether the public interest requires that the letter shall not be produced and whether that public interest is so strong as to override the ordinary right and interest of a litigant that he shall be able to lay before a court of justice all relevant evidence.’
