“The meaning of the expression “particular documents specified in the order” in subsection (4)(b) was concerned by several of the noble and learned lords who took part in the Westinghouse case [1978] A.C.547 decision. They were all emphatic that the expression should be given a strict construction. Having regard to the purpose of subsection (4) which, as I have already mentioned, is to preclude pre-trial expeditions Lord Wilberforce said, at p.609: ‘These provisions, and especially the words “’particular documents specified in the order’ (replacing ‘documents to be mentioned in the order’ in the [Foreign Tribunals Evidence Act] 1856) together with the expressed duty of the English court to decide that the documents are or are likely to be in the possession, custody or power of the person called upon to produce, show, in my opinion, that a strict attitude is to be taken by English courts in giving effect to foreign requests for the production of documents by non-party witnesses. They are, in the words of Lord Goddard C.J., not to countenance ‘fishing’ expeditions: Radio Corporation of America v. Rauland Corporation [1956] 1 Q. B. 618, 649.” ‘These provisions, and especially the words “’particular documents specified in the order’ (replacing ‘documents to be mentioned in the order’ in the [Foreign Tribunals Evidence Act] 1856) together with the expressed duty of the English court to decide that the documents are or are likely to be in the possession, custody or power of the person called upon to produce, show, in my opinion, that a strict attitude is to be taken by English courts in giving effect to foreign requests for the production of documents by non-party witnesses.
