The tendency of a fact offered as evidence in a lawsuit to prove or disprove the truth of a point in issue.
A fact offered as evidence must bear a logical relationship to a point in issue for the court to permit its admission as evidence. In addition to such relevancy, evidence must also be material; it must strongly establish the truth or falsity of a point in issue if it is to be used as proof of a particular issue.
RELEVANCY. By this term is understood the evidence which is applicable to the issue joined; it is relevant when it is applicable to the issue, and ought to be admitted; it is irrelevant, when it does not apply; and it ought then to be excluded. 3 Hawks, 122; 4 Litt.
