Evidence Rules

Evidence (Fall - 2026) - Jolly

Rule 104(b) Preliminary Questions - Relevance That Depends on Fact

When the relevance of evidence depends on whether a fact exists, proof must be introduced sufficient to support a finding that the fact does exist. The court may admit the proposed evidence on the condition that the proof be introduced later.

Rule 403 Excluding Relevant Evidence for Prejudice, Confusion, Waste of Time, or Other Reasons

The court may exclude relevant evidence if its probative value is substantially outweighed by a danger of one or more of the following: unfair prejudice, confusing the issues, misleading the jury, undue delay, wasting time, or needlessly presenting cumulative evidence.

Rule 606(b) Juror's Competency as a Witness - During an Inquiry into the Validity of a Verdict or Indictment

(1) Prohibited Testimony or Other Evidence. During an inquiry into the validity of a verdict or indictment, a juror may not testify about any statement made or incident that occurred during the jury’s deliberations; the effect of anything on that juror’s or another juror’s vote; or any juror’s mental processes concerning the verdict or indictment. The court may not receive a juror’s affidavit or evidence of a juror’s statement on these matters.

Rule 606(b)(2) Exceptions

(2) Exceptions. A juror may testify about whether:

      a. extraneous prejudicial information was improperly brought to the jury’s attention;

      b. an outside influence was improperly brought to bear on any juror; or

      c. a mistake was made in entering the verdict on the verdict form.

Rule 105 Limiting Evidence That Is Not Admissible Against Other Parties or for Other Purposes

If the court admits evidence that is admissible against a party or for a purpose — but not against another party or for another purpose — the court, on timely request, must restrict the evidence to its proper scope and instruct the jury accordingly.

Rule 401 Test for Relevant Evidence

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.

Rule 102 Purpose

These rules should be construed so as to administer every proceeding fairly, eliminate unjustifiable expense and delay, and promote the development of evidence law, to the end of ascertaining the truth and securing a just determination.

Rule 402 General Admissability of Relevant Evidence

Relevant evidence is admissible unless any of the following provides otherwise:

   - the United States Constitution;

   - a federal statute;

   - these rules; or

   - other rules prescribed by the Supreme Court.

Irrelevant evidence is not admissible.

Rule 407 Subsequent Remedial Measures

When measures are taken that would have made an earlier injury or harm less likely to occur, evidence of the subsequent measures is not admissible to prove:

- negligence;

- culpable conduct;

- a defect in a product or its design; or

- a need for a warning or instruction.

But the court may admit this evidence for another purpose, such as impeachment or — if disputed — proving ownership, control, or the feasibility of precautionary measures.

Rule 411 Liability Insurance

Evidence that a person was or was not insured against liability is not admissible to prove whether the person acted negligently or otherwise wrongfully. But the court may admit this evidence for another purpose, such as proving a witness’s bias or prejudice or proving agency, ownership, or control.

Rule 408 Compromise Offers and Negotiations

(a) Prohibited Uses. Evidence of the following is not admissible — on behalf of any party — either to prove or disprove the validity or amount of a disputed claim or to impeach by a prior inconsistent statement or a contradiction:

(1) furnishing, promising, or offering — or accepting, promising to accept, or offering to accept — a valuable consideration in compromising or attempting to compromise the claim; and

(2) conduct or a statement made during compromise negotiations about the claim — except when offered in a criminal case and when the negotiations related to a claim by a public office in the exercise of its regulatory, investigative, or enforcement authority.

(b) Exceptions. The court may admit this evidence for another purpose, such as proving a witness’s bias or prejudice, negating a contention of undue delay, or proving an effort to obstruct a criminal investigation or prosecution.

Rule 409 Offers to Pay Medical and Similar Expenses

Evidence of furnishing, promising to pay, or offering to pay medical, hospital, or similar expenses resulting from an injury is not admissible to prove liability for the injury.

Rule 410 Pleas, Plea Discussions, and Related Statements

(a) Prohibited Uses. In a civil or criminal case, evidence of the following is not admissible against the defendant who made the plea or participated in the plea discussions:

(1) a guilty plea that was later withdrawn;

(2) a nolo contendere plea;

(3) a statement made during a proceeding on either of those pleas under Federal Rule of Criminal Procedure 11 or a comparable state procedure; or

(4) a statement made during plea discussions with an attorney for the prosecuting authority if the discussions did not result in a guilty plea or they resulted in a later-withdrawn guilty plea.

(b) Exceptions. The court may admit a statement described in Rule 410(a)(3) or (4):

(1) in any proceeding in which another statement made during the same plea or plea discussions has been introduced, if in fairness the statements ought to be considered together; or

(2) in a criminal proceeding for perjury or false statement, if the defendant made the statement under oath, on the record, and with counsel present.

Rule 404(a)(1) - Character Evidence

(a) Character Evidence.

(1) Prohibited Uses. Evidence of a person’s character or character trait is not admissible to prove that on a particular occasion the person acted in accordance with the character or trait.

Rule 404(b) - Other Crimes, Wrongs, or Acts

(1) Prohibited Uses. Evidence of any other crime, wrong, or act is not admissible to prove a person’s character in order to show that on a particular occasion the person acted in accordance with the character.

(2) Permitted Uses. This evidence may be admissible for another purpose, such as proving motive, opportunity, intent, preparation, plan, knowledge, identity, absence of mistake, or lack of accident.

(3) Notice in a Criminal Case. In a criminal case, the prosecutor must:

(A) provide reasonable notice of any such evidence that the prosecutor intends to offer at trial, so that the defendant has a fair opportunity to meet it;

(B) articulate in the notice the permitted purpose for which the prosecutor intends to offer the evidence and the reasoning that supports the purpose; and

(C) do so in writing before trial — or in any form during trial if the court, for good cause, excuses lack of pretrial notice.

Rule 406 - Habit; Routine Practice

Evidence of a person’s habit or an organization’s routine practice may be admitted to prove that on a particular occasion the person or organization acted in accordance with the habit or routine practice. The court may admit this evidence regardless of whether it is corroborated or whether there was an eyewitness.

Rule 405 - Methods of Proving Character

(a) By Reputation or Opinion. When evidence of a person’s character or character trait is admissible, it may be proved by testimony about the person’s reputation or by testimony in the form of an opinion. On cross-examination of the character witness, the court may allow an inquiry into relevant specific instances of the person’s conduct.

(b) By Specific Instances of Conduct. When a person’s character or character trait is an essential element of a charge, claim, or defense, the character or trait may also be proved by relevant specific instances of the person’s conduct.

Rule 609 - Impeachment by Evidence of a Criminal Conviction

(a) In General. The following rules apply to attacking a witness’s character for truthfulness by evidence of a criminal conviction:

(1) for a crime that, in the convicting jurisdiction, was punishable by death or by imprisonment for more than one year, the evidence:

(A) must be admitted, subject to Rule 403, in a civil case or in a criminal case in which the witness is not a defendant; and

(B) must be admitted in a criminal case in which the witness is a defendant, if the probative value of the evidence outweighs its prejudicial effect to that defendant; and

(2) for any crime regardless of the punishment, the evidence must be admitted if the court can readily determine that establishing the elements of the crime required proving — or the witness’s admitting — a dishonest act or false statement.

(b) Limit on Using the Evidence After 10 Years. This subdivision (b) applies if more than 10 years have passed since the witness’s conviction or release from confinement for it, whichever is later. Evidence of the conviction is admissible only if:

(1) its probative value, supported by specific facts and circumstances, substantially outweighs its prejudicial effect; and

(2) the proponent gives an adverse party reasonable written notice of the intent to use it so that the party has a fair opportunity to contest its use.

(c) Effect of a Pardon, Annulment, or Certificate of Rehabilitation. Evidence of a conviction is not admissible if:

(1) the conviction has been the subject of a pardon, annulment, certificate of rehabilitation, or other equivalent procedure based on a finding that the person has been rehabilitated, and the person has not been convicted of a later crime punishable by death or by imprisonment for more than one year; or

(2) the conviction has been the subject of a pardon, annulment, or other equivalent procedure based on a finding of innocence.

(d) Juvenile Adjudications. Evidence of a juvenile adjudication is admissible under this rule only if:

(1) it is offered in a criminal case;

(2) the adjudication was of a witness other than the defendant;

(3) an adult’s conviction for that offense would be admissible to attack the adult’s credibility; and

(4) admitting the evidence is necessary to fairly determine guilt or innocence.

(e) Pendency of an Appeal. A conviction that satisfies this rule is admissible even if an appeal is pending. Evidence of the pendency is also admissible.

Rule 607 - Who May Impeach a Witness

Any party, including the party that called the witness, may attack the witness’s credibility.

Rule 608 - A Witness’s Character for Truthfulness or Untruthfulness

(a) Reputation or Opinion Evidence. A witness’s credibility may be attacked or supported by testimony about the witness’s reputation for having a character for truthfulness or untruthfulness, or by testimony in the form of an opinion about that character. But evidence of truthful character is admissible only after the witness’s character for truthfulness has been attacked.

(b) Specific Instances of Conduct. Except for a criminal conviction under Rule 609, extrinsic evidence is not admissible to prove specific instances of a witness’s conduct in order to attack or support the witness’s character for truthfulness. But the court may, on cross-examination, allow them to be inquired into if they are probative of the character for truthfulness or untruthfulness of:

(1) the witness; or

(2) another witness whose character the witness being cross-examined has testified about.

By testifying on another matter, a witness does not waive any privilege against self-incrimination for testimony that relates only to the witness’s character for truthfulness.

Rule 415 - Similar Acts in Civil Cases Involving Sexual Assault or Child Molestation

(a) Permitted Uses. In a civil case involving a claim for relief based on a party’s alleged sexual assault or child molestation, the court may admit evidence that the party committed any other sexual assault or child molestation. The evidence may be considered as provided in Rules 413 and 414.

(b) Disclosure to the Opponent. If a party intends to offer this evidence, the party must disclose it to the party against whom it will be offered, including witnesses’ statements or a summary of the expected testimony.
