According to the ACFE Fraud Examiners Manual, Law Section, specifically under Basic Principles of Evidence and Admissibility of Evidence , relevant evidence is defined as evidence having any tendency to make a fact that is of consequence to the determination of the action more or less probable than it would be without the evidence. This definition focuses on the logical relationship between the evidence and a disputed issue in the case.

Relevance is a foundational requirement for admissibility. If evidence does not bear on a material fact in dispute, it is generally inadmissible because it does not assist the trier of fact in resolving the matter. The threshold for relevance is relatively low; the evidence need only slightly increase or decrease the probability of a consequential fact.

Circumstantial evidence refers to indirect evidence that requires inference to connect it to a conclusion of fact, while testimonial evidence consists of statements made by a witness under oath. Demonstrative evidence includes physical objects, models, or visual aids used to illustrate testimony. Although these are types or forms of evidence, they are not definitions of the concept described in the question.

Therefore, the correct term for evidence that makes a disputed fact more or less likely is relevant evidence.
