Section 43 of the Indian Evidence Act deals with the relevance of judgments, orders, or decrees that are not specifically covered by Sections 40, 42, and 43. It states that such judgments are generally considered irrelevant as evidence unless the existence of the judgment is a fact in issue in the case or is relevant under another provision of the Act. In other words, judgments outside the scope of Sections 40-42 must directly relate to the issues in the current case or be allowed under another evidentiary rule to be admissible. The section provides clarity around the limited circumstances where other judgments can be introduced as evidence.
