Relevance (law)
Core legal principle determining whether evidence is admissible in court.
Relevance, in the common law of evidence, is the tendency of a given item of evidence to prove or disprove one of the legal elements of the case, or to have probative value to make one of those elements likelier or not. Probative evidence "seeks the truth," and evidence that is not probative—that does not tend to prove the proposition for which it is offered—is generally inadmissible and may be excluded from a proceeding or stricken from the record if objected to by opposing counsel. A balancing test may be applied when the value of the evidence must be weighed against its prejudicial nature. Under the Federal Rules of Evidence in the United States, Rule 401 originally defined relevance as requiring evidence to be both material, meaning of consequence to the determination of the action, and to have probative value, meaning any tendency to make a material fact more or less probable. The restyled Rule 401 now presents relevance as a test rather than a definition. The Advisory Committee notes explain that evidence is relevant if it relates to a matter properly provable in the case. The United States Court of Appeals for the District of Columbia Circuit further clarifies that this includes any fact that is of consequence to the determination of the action. While all evidence must have probative value to be admitted, not all relevant evidence is admissible; it may be prohibited by the Constitution, an Act of Congress, the Federal Rules of Evidence, or Supreme Court rules. Under Rule 403, relevant evidence may be excluded if its probative value is substantially outweighed by unfair prejudice, confusion of the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence. For example, character evidence such as old convictions for unrelated crimes is often excluded because, while it may have probative value, it is too prejudicial, as juries might convict to punish past behavior. To preserve legal error for review, objections must be specific and timely; objecting solely on the basis of relevance does not preserve an error under Rule 403. Public policy also excludes relevant evidence such as liability insurance, subsequent remedial measures, settlement offers, and plea negotiations, to avoid discouraging insurance, hazard fixes, settlements, or guilty pleas. In Canada, the term "probative" is used, and the Supreme Court in R. v

Lore & Background
In Canada, the term 'probative' is used, signifying 'prove to be worthy.' The Supreme Court of Canada in R. v. Wray addressed exclusionary discretion, stating that judges in criminal cases do not have discretion to exclude evidence because of how it was obtained, but may exclude evidence of little probative value but great prejudicial effect. In Australia, the Uniform Evidence Act defines relevance as evidence that, if accepted, could rationally affect the assessment of the probability of a fact in issue. Logical relevance requires only a logical connection to the facts, while legal relevance involves a discretionary exclusion where probative value is substantially outweighed by unfair prejudice.
Reader's Guide
The significance of relevance lies in its role as the gatekeeper for evidence in legal proceedings. Without relevance, evidence is inadmissible, ensuring that trials focus on facts that actually matter to the case. The concept balances the need for probative evidence against the risk of unfair prejudice, confusion, or waste of time. This balancing test is crucial in preventing juries from being swayed by emotionally charged but marginally probative evidence, such as character evidence of past crimes. In Canada and Australia, similar balancing tests exist, reflecting a shared common law tradition. The legacy of relevance is its enduring role in shaping fair trials, ensuring that evidence is both logically connected to the case and not unduly harmful to the integrity of the proceeding.

- The Advisory Committee noted that relevancy is not an inherent characteristic of evidence but exists only as a relation between an item of evidence and a matter properly provable in the case.
- In Canada, the Supreme Court in R. v. Wray held that judges do not have discretion to exclude evidence because of how it was obtained, only for little probative value with great prejudicial effect.
- In Australia, evidence is relevant if it could rationally affect the assessment of the probability of a fact in issue, even if only slight probative value.
