Rule 403 - Courts Discretion to Exclude
A trial judge has broad discretion to exclude relevant evidence if its probative value is substantially outweighed by the danger of one or more of the following considerations:
* Danger of unfair prejudice
* Confusion of the issues
* Misleading the jury
* Undue delay
* Wase of time
* Needless presentation of cumlative evidence
Plaintiff’s Accident History
Evidence that a person has previously filed similar tort claims or has been involved in prior accidents is generally inadmissible to show the invalidity of the present claim; all it demonstrates is that the person is litigious or accident-prone.
However, such evidence may be admissible if it tends to show something other than carelessness:
Similar Accidents of Injuries Caused by the Same Event or Condition
Generally, other accidents involving the defendant are inadmissible because they merely show the defendant’s general character for carelessness.
However, evidence of prior accidents or injuries caused by the same event or condition and occurring under substantially similar circumstances is admissible to prove:
1. the existence of a dangerous condition,
2. that the dangerous condition was the cause of the present injury, and
3. that the defendant had notice of the dangerous condition (if the other accident occurred before the plaintiff’s accident).
Previous Similar Acts to Prove Intent
Similar conduct previously committed by a party may be admissible to prove the party’s present motive or intent in the current case.
Rebutting Claim of Impossibility
The requirement that prior occurrences be similar to the litigated act may be relaxed when used to rebut a claim of impossibility.
Habit/Business Routine Evidence
Evidence of a person’s habit (or evidence of the routine practice of an organization) is admissible as circumstantial evidence that the person (or organization) acted in accordance with the habit on the occasion at issue in the case.
Habit describes a person’s regular response to a specific set of circumstances. Thus, there are 2 defining characteristics of habit: (1) frequency of conduct and (2) particularity of circumstances.
Liability Insurance
Evidence of a party’s insurance against liability (or lack thereof) is not admissible to show whether the party acted negligently or otherwise wrongfully (meaning, it is inadmissible to prove the party’s fault or absence of fault). However, it may be admissible for other relevant purposes, such as:
Subsequent Remedial Measures
Evidence of repairs or other precautionary measures made following an injury is not admissible to prove negligence, culpable conduct, a defect in a product or its design, or a need for a warning or instruction.
However, it may be admissible for some other relevant purpose, such as:
Civil Settlements
Settlement Negotiations
Evidence of a compromise (settlement) or an offer to compromise a civil claim is not admissible in any case to: (1) prove or disprove the validity or amount of a disputed claim, or (2) impeach a witness by prior inconsistent statement or contradiction.
Conduct or statements made in the course of negotiating a compromise—including direct admissions of liability—are also inadmissible for these purposes.
The public policy exclusion for settlements and negotiations only kicks in if there was a claim or some indication that a party was going to make a claim (although the party need not have actually filed suit). Furthermore, the claim must have been in dispute as to either (1) liability or (2) amount.
Plea Discussions
The following are generally inadmissible in any criminal or civil case against the defendant who made the plea or participated in the discussions:
Note: An actual guilty plea (not withdrawn) is generally admissible in related litigation as a statement of an opposing party (see the Hearsay module).
Payments Of/Offers to Pay
Medical Expenses
Evidence that a party has paid or offered to pay an injured person’s medical, hospital, or similar expenses is inadmissible to prove liability for the injury. However, unlike the situation with settlement negotiations, admissions of fact accompanying such payments and offers are admissible.
Defendant’s Character in a Criminal Case
The prosecution cannot initiate evidence of the defendant’s bad character to show conduct in conformity.
In other words, they can’t introduce such evidence during their case-in-chief to show that it is within the defendant’s character to commit the charged crime. However, because the defendant’s life or liberty is at stake, the defendant is permitted to introduce evidence of their own good character to show their innocence.
If the defendant introduces evidence of their good character, then the prosecution can rebut with evidence of the defendant’s bad character.
How a Defendant Proves Character
Under the Federal Rules, a character witness for the defendant may testify as to the defendant’s good reputation for a pertinent trait and may give their personal opinion concerning that trait of the defendant.
Victim’s Character in a Criminal Case
Except in sexual assault cases, the defendant may introduce reputation or opinion evidence of a bad character trait of the alleged crime victim when it is relevant to show the defendant’s innocence.
Although a victim’s character usually has no bearing on the defendant’s innocence, it becomes relevant when the defendant claims self-defense and argues that the victim was the first aggressor.
Authentication of Writings and Spoken Statements
As a general rule, a writing or any secondary evidence of its content will not be received in evidence unless the writing is authenticated by proof that shows that the writing is what the proponent claims it is.
The proof must be sufficient to support a jury finding of genuineness (that is, a reasonable juror could conclude that the writing is genuine).
Methods of Document Authentication
Ancient Document Authethentication
A document can be authenticated by evidence that it:
Reply Letter Doctrine
Authentication
A writing can be authenticated by evidence that it was written in response to a communication sent to the alleged author.
Photograph and Videos Authethentication
Generally, photographs and videos are admissible only if identified by a witness as a portrayal of certain facts relevant to the issue and verified by the witness as a fair and accurate representation of those facts.
Ordinarily, it is not necessary to call the photographer to authenticate the photograph or video; a witness familiar with the scene, object, or person is sufficient.
Unattended Camera—Proper Operation of Camera
If a photograph or video is taken when no person who could authenticate the scene is present, the photograph or video may be admitted upon a showing that the camera was properly operating at the relevant time and that the photograph or video was downloaded from that camera or developed from film obtained from that camera.
X-Rays, Electrocardiograms, Etc. Authetication
Unlike photographs, an X-ray cannot be authenticated by testimony of a witness that it is a correct representation of the facts.
It must be shown that the process used is accurate, the machine was in working order, and the operator was qualified to operate it.
Finally, a custodial chain must be established to assure that the X-ray has not been tampered with.
Authentication of Oral Statements
When a statement is admissible only if said by a particular person (for example, as a statement by an opposing party), authentication as to the identity of the speaker is required.
Self-Authenticating Documents
Extrinsic evidence of authenticity is not required for the following:
Best Evidence Rule
This rule is more accurately called the “original document rule.”
To prove the content of a writing, recording, or photograph, the original writing must be produced if the terms of the writing are material.
Secondary evidence of the writing, such as oral testimony, is admissible only if the proponent provides a satisfactory excuse for the original’s absence.
The rule applies in 2 principal situations:
* Where the writing is a legally operative or dispositive instrument
(that is, the writing itself creates rights and obligations); or
* Where the knowledge of a witness concerning a fact results from having read it in the writing
The rule does not apply where the witness has personal knowledge of the fact to be proved, even if the fact happens to also be recorded in a writing. Oral testimony of the fact may be given without producing the original writing that recorded the event.
Duplicates vs. Originals
Original—The writing itself or any counterpart that is intended by the person executing it to have the same effect as an original. This includes the negative of a photograph or any print of it, or the printout or other readable output of electronically stored information.
Duplicate—An exact copy of an original made by mechanical means (for example, a photocopy or carbon copy).
Duplicates are admissible to the same extent as originals, unless:
1. the circumstances make it unfair to admit the duplicate, or
2. a genuine question is raised about the authenticity of the original.
