What documents relating to the matters in question should be disclosed in an affidavit?

In my opinion reference in the present rule 188 to "what documents relating to the matters in question" means only the relevant portions of what might physically be called a document. If part only of a page is relevant then that is the document that must be disclosed in the affidavit. As stated in Williston and Rolls, Law of Civil Procedure at p. 898:- "If only part of a document is relevant the proper course is either to disclose only the relevant part or disclose the whole document with a claim to seal up the irrelevant part or the part which is not material may be covered up during the inspection." In my opinion this is a correct statement of the law. See cases cited by the authors and Royal Bank v. Wallis supra.
