Relevant means that which is logical probative. Admissibility is not based on logic but on law and strict rules. Many facts having no bearing on the facts to be proved are admissible. The proof of loss of original deed has no effect on the decision of the issue but, this is admissible evidence before secondary evidence about the content of the relevant document may be given. In the Indian Evidence Act, the question of relevancy has been dealt with under section 6 to 55 and that of admissibility from section 56 onwards. Rules of relevancy declare certain facts relevant. Rules of admissibility law down, as to whether a certain form of evidence about the relevant fact may be allowed or excluded. The facts that are allowed to be proved (Section 6 to 55) are3 called relevant facts. The admissibility is the means and the method of proving the relevant facts. In Ram Bihari Yadav v. State of Bihar, AIR 1998 SC 1850, the Supreme Court speaking through Mohd. Quadari J. said that more often than not the expression ‘relevancy’ and ‘admissibility’ are sued as synonym but their implications are different because facts which are relevant may not be admissible, for example, the communication between spouse during marriage; communication between an advocate and his client, through relevant are not admissible.
