“The rule that a party or witness has immunity in respect of what he says and does in court has been established for centuries.”
“… no action lies against parties or witnesses for anything said or done, although falsely and maliciously and without any reasonable or probable cause, in the ordinary course of any proceeding in a court of justice.”
“… there is another factor that must always be balanced against the public interest in matters relating to the administration of justice. It is the principle that a wrong ought not to be without a remedy. The immunity is a derogation from a person’s right of access to the court which requires to be justified.”
“The actions which the police take as law enforcers or as investigators may … become the subject of evidence. It may then be necessary for the police officers concerned to assume the functions of witnesses at the trial to describe what they did or what they heard or what they saw. But there is no good reason or grounds of public policy to extend the immunity which attaches to things said or done by them when they are describing these matters to things done by them which cannot fairly be said to form part of their participation in the judicial process as witnesses. The purpose of the immunity is to protect witnesses against claims made against them for something said or done in the course of giving or preparing to give evidence. It is not to be used to shield the police from action for things done while they are acting as law enforcers or investigators.”
“This distinction rests upon the fact that acts which are calculated to create or procure false evidence or to destroy evidence have an independent existence from, and are extraneous to, the evidence that may be given as to the consequences of those acts.”
“In my view the approach there taken to the scope of the immunity was too widely expressed. To extend it to cover all conduct that can fairly be said to be part of the investigatory or preparatory process takes it beyond the length of the intimate connection with the court proceedings and the extent which is necessary for the purposes for which it is granted.”
“There is, in my opinion, a distinction in principle between what a witness says in court (or what in a proof of evidence a prospective witness states he will say in court) and the fabrication of evidence …”
“That does not mean that everything they create is subject to the immunity. The distinction which Lord Hutton describes … may be even finer in this case but it is real nonetheless. There is a difference between the material created when making inquiries and the witness statement then prepared for the judicial process … It does not seem to me that the distinction between a statement and an exhibit is any more fine or invidious than that drawn between writing down a false confession in advance on the one hand and falsely claiming this later in the witness box, on the other … The exhibits are material collected on which the potential witness may be called to give evidence and are not, as I see it, subject to the immunity.”
“It does not seem to me that the distinction between a statement and an exhibit is any more invidious than that drawn [in Darker] between writing down a false confession in advance on the one hand and falsely claiming this later in the witness box on the other.”
“I do not think that it can be asserted without hearing the evidence that these allegations fall within the boundaries of the immunity. This is a matter which should be considered in the light of the facts as they emerge at the trial.”
