Article 158(1) also relates to admissibility.
Example of Admissibility & relevancy:
any document related to Fact in issue/subject matter is relevant, but the way in which it is to be presented it is matter of admissibility. if plaintiff wants to produce copy of that document (secondary evidence) instead of original one, in case where original is available and is not a public document, then his way of producing such copy would not be Admissibile, but if it is proved that original is missing, then presentation of such document via copy would be considered Admissibile.
