Relevance is the first hurdle every piece of evidence must clear. When evidence is challenged, the proponent must articulate how the evidence connects to a fact at issue in the case. Even if evidence is relevant under Rule 401, the court may still exclude it under Rule 403 if its probative value is substantially outweighed by the danger of unfair prejudice, confusion of the issues, misleading the jury, undue delay, or needless presentation of cumulative evidence. Judges have broad discretion in making Rule 403 balancing determinations.
Attorney: "I offer Exhibit 7, a photograph of the intersection." Opposing Counsel: "Objection, relevance." Attorney: "Your Honor, this photograph shows the sight lines available to my client, which is directly relevant to whether she exercised reasonable care."
Judge: "Counsel, how is the defendant's prior bankruptcy relevant to this breach of contract claim?" Attorney: "It goes to motive, Your Honor. The defendant had a financial incentive to breach."
Opposing Counsel: "Your Honor, even if marginally relevant, this evidence should be excluded under 403. The gruesome photographs will inflame the jury and their prejudicial effect substantially outweighs any probative value."
Students often confuse relevance with sufficiency. A single piece of evidence need not prove an entire element of a claim — it only needs to make a consequential fact slightly more or less probable. Additionally, the Rule 403 standard is "substantially outweighs," not merely "outweighs."
Old Chief v. United States, 519 U.S. 172 (1997)
Held that a court abused its discretion by refusing a defendant's offer to stipulate to a prior felony conviction and instead admitting the full record of the prior offense, as the stipulation had equal probative value with far less prejudice.
Sprint/United Management Co. v. Mendelsohn, 552 U.S. 379 (2008)
Clarified that relevance determinations regarding "me too" evidence in employment discrimination cases require case-by-case analysis under Rules 401 and 403 rather than categorical rules.
United States v. Abel, 469 U.S. 45 (1984)
Confirmed that evidence of witness bias is always relevant and that trial courts have broad discretion in applying the Rule 403 balancing test to determine admissibility.
What is the standard for relevance under the Federal Rules of Evidence?
Under Rule 401, evidence is relevant if it has any tendency to make a fact of consequence more or less probable than it would be without the evidence. This is an intentionally low threshold — even a slight probative connection satisfies the relevance requirement.
What is the Rule 403 balancing test?
Rule 403 allows a court to exclude relevant evidence if its probative value is substantially outweighed by the danger of unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence. The key word is "substantially" — mere prejudice is not enough.
Can relevant evidence still be excluded from trial?
Yes, relevant evidence can be excluded through several mechanisms: Rule 403 balancing, privilege rules, hearsay rules, character evidence restrictions, and other specific exclusionary rules. Relevance is necessary but not sufficient for admissibility.
What is the difference between relevance and materiality?
Under the pre-Federal Rules common law, relevance and materiality were distinct concepts. Modern Rule 401 combines them: evidence must relate to a "fact of consequence" (materiality) and must make that fact more or less probable (logical relevance). Both elements must be present.
