is a term used in the law
to describe any testimony or document submitted for the purpose of proving that a person acted in a particular way on a particular occasion based on the character or disposition of that person. There are three ways that such evidence might be presented in a court of law,
- Testimony as to prior bad acts by the individual
- Witness's own opinion as to the character of the individual
- Testimony as to the reputation of the individual.
Character evidence is generally inadmissible in civil
suits, because it is considered to be an unfair basis from which to attempt to prove that an individual behaved in a particular way on a particular occasion. However, there are specific instances in which this kind of evidence is admissible. In particular, when an individual claims to have good character (particularly when a witness claims to be honest or peaceful), the opposing side can rebut
this claim by introducing character evidence against that individual.
Character evidence may be admitted where the character of the party is an element of the claim—for example, in a defamation claim where party A sues party B because B said that A is dishonest. In such a claim, B can introduce evidence that A has a reputation as a dishonest person.
trials, the defendant
may always introduce opinion evidence or reputation evidence to prove that they did not commit the crime of which they are accused. However, if a criminal defendant does introduce such evidence, the prosecution
may then counter this with evidence of the defendant's bad character. The defendant cannot introduce evidence of specific good acts to show that he did not commit a bad act.
When someone other than the defendant testifies as to the defendant's good character, the prosecution may ask if the witness was aware of specific bad acts done by the defendant. This is permissible because the question is not asked to prove the defendant's character, but simply to impeach the credibility of the witness.
Another exception arises in criminal trials where the defendant introduces evidence of the character of the alleged crime victim, in order to show that the defendant acted in self defense. For example, if the defendant is on trial for battery of the victim, the defendant can introduce evidence that the victim has a reputation for violence, or that a witness has the opinion that the victim is a violent person, in order to show that the defendant actually acted in self defense. The prosecution may counter this by introducing similar evidence of the victim's peaceful nature, or by introducing similar evidence of the defendant's violent nature.
Commentators have noted that the ability of defendants to call character witnesses can give an advantage to more affluent defendants. Affluent defendants can call, as character witnesses, celebrities, athletes, and prominent members of the community. Contrastingly, it is not unknown for death row inmates to sometimes call, as a character witness, fellow death row inmates.
Distinguished from habit evidence
Character evidence must be distinguished from habit evidence
, which describes conduct that an individual engages in as a matter of course, without giving it any thought.
