The essential elements for an order for discovery were explained in the case of Yekambaran s/o Marimuthu v Malayawata Steel Berhad [1994] 2 CLJ 581, as follows: “The essential elements for an order for discovery are threefold; namely, first there must be a "document", secondly, the document must be "relevant" and thirdly, the document must be or have been in the "possession, custody or power" of the party against whom the order for discovery is sought. ...... As to "relevance", our Rules of the High Court limit discovery to documents which are "relevant to" or "relate" to the factual issues in dispute. More particularly, the discovery obligation applies to documents "relating to matters in question in the action" [Rules of the High Court, O. 24, r. 1(1)] or "relating to any matter in question in the cause or matter" [O. 24, r. 3(1)]. In practice, relevance is primarily determined by reference to the pleadings but there need not be a pleading for a matter to be said to be in issue. (See Phillips v. Phillips [1879] 40 LT 815, 821. In this context, relevance is defined broadly. It does not extend to documents relevant merely to a party's credibility unless that itself is a fact in issue. (See George Ballantine & Sons Ltd. v. Dixon & Son Ltd. [1974] 1 WLR 1125). If, however, the document's relevance is to a fact in issue, not simply to credibility, it has long been settled that relevance of an indirect kind suffices.” [emphasis added]
