Source: FRE Rule 401

Official Text
Evidence is relevant if: (a) it has any tendency to make a fact more or less probable than it would be without the evidence; and (b) the fact is of consequence in determining the action.
Plain Language

Rule 401 states that evidence is relevant if it can make a fact more or less likely than without that evidence, and that fact must matter in the context of the case. In simple terms, relevant evidence helps to prove or disprove important points in a trial.

Purpose

The purpose of Rule 401 is to ensure that only evidence that has a meaningful connection to the facts of the case is presented in court, thereby preventing irrelevant information from influencing the jury.

Key Provisions

(a)

This provision assesses whether the evidence has any tendency to alter the probability of a fact being true, establishing a threshold for relevance.

(b)

This provision requires that the fact to which the evidence relates must be of material importance to the legal issues being resolved in the case.

Practice Notes
  • When evaluating relevance, consider both the probative value and the potential for unfair prejudice.
  • Ensure that any evidence introduced is tied directly to a pertinent fact in the case.
  • Remember that evidence can be relevant even if it does not prove a fact conclusively; it only needs to have some tendency to affect the likelihood of the fact.
Landmark Cases

United States v. James

This case illustrated how Rule 401 is applied to evaluate evidence based on its ability to make a fact more or less probable, emphasizing the need for a clear connection between the evidence and the issues at hand.

Huddleston v. United States

In this case, the court clarified that the admissibility of evidence under Rule 401 is not solely based on its overall relevance but also on its specific connection to the material facts of the case.

Exam Tip

When preparing for exams, be prepared to analyze the relevance of evidence presented in hypothetical scenarios, and apply Rule 401 to determine its admissibility.
