Mahon v Rahn: QBD 19 Jun 1996

Directors of a London firm of stockbrokers brought libel proceedings against two Swiss bankers.
Held: The absolute immunity which is given to both witnesses and potential witnesses extends to all those taking part in a criminal investigation which is being conducted looking forward to a prosecution. The general principle was that the use of documents disclosed for the purpose of legal proceedings should remain under the control of the court. The implied undertaking could always be varied in an appropriate case but the court should retain control. It was a necessary tool for preventing its process from being abused. The undertaking applied to material disclosed by the prosecution as intended to be used at the trial as well as to unused material and that it survived the use of the document in open court.
