When a fact is connected with another fact, it is logically relevant but it is relevant if the law declares it to be relevant. If it is not declared by the law to be relevant, it is not admissible in evidence. Under the Evidence Act, a fact is said to be relevant to another when it is relevant under the provisions of Sections 6 to 55 of Evidence Act.
Section 3 of the Indian Evidence Act, 1872 defines “Relevant”-One fact is said to be relevant to another when the one is connected with the other in any of the ways referred to in the provisions of this Act relating to the relevancy of facts.
