Relevancy

As a quality of evidence, "relevancy" means applicability to the issue joined. Relevancy is that which conduces to the proof of a pertinent hypothesis; a pertinent hypothesis being one which, if sustained, would logically influence the issue.

Whart. Ev. § 20.

In Scotch law, the relevancy is the justice or sufficiency in law of the allegations of a party. A plea to the relevancy is therefore analogous to the demurrer of the English courts. A distinction is sometimes taken between "logical" relevancy and "legal" relevancy, the former being judged merely by the standards of ordinary logic or the general laws of reasoning, the latter by the strict and artificial rules of the law with reference to the admissibility of evidence.
