- Relevancy of facts in a court case is governed by the Indian Evidence Act, 1872. - Facts forming part of the same transaction, facts showing motive, preparation, conduct, or relationship of parties are often relevant under Sections 6-16 of the Act. - In a defamation case, facts related to the relationship, background, and circumstances surrounding the publication of the statement are relevant to understand the context and evaluate the claim and defense. - A dispute on an entirely unrelated matter, without a link to the alleged libel, is generally considered irrelevant as it does not help prove or disprove the truth of the libel or the circumstances of its publication.
