Federal Rules of Evidence - Rule 404. Character Evidence Not Admissible To Prove Conduct; Exceptions; Other Crimes
(a) Character evidence generally
Evidence of a person's character or a trait of character is not admissible for the purpose of proving action in conformity therewith on a particular occasion, except:
(1) Character of accused - In a criminal case, evidence of a pertinent trait of character offered by an accused, or by the prosecution to rebut the same, or if evidence of a trait of character of the alleged victim of the crime is offered by an accused and admitted under Rule 404 (a)(2), evidence of the same trait of character of the accused offered by the prosecution;
(2) Character of alleged victim - In a criminal case, and subject to the limitations imposed by Rule 412, evidence of a pertinent trait of character of the alleged victim of the crime offered by an accused, or by the prosecution to rebut the same, or evidence of a character trait of peacefulness of the alleged victim offered by the prosecution in a homicide case to rebut evidence that the alleged victim was the first aggressor;
(b) Other crimes, wrongs, or acts
Evidence of other crimes, wrongs, or acts is not admissible to prove the character of a person in order to show action in conformity therewith. It may, however, be admissible for other purposes, such as proof of motive, opportunity, intent, preparation, plan, knowledge, identity, or absence of mistake or accident, provided that upon request by the accused, the prosecution in a criminal case shall provide reasonable notice in advance of trial, or during trial if the court excuses pretrial notice on good cause shown, of the general nature of any such evidence it intends to introduce at trial.
Although character evidence and similar crimes evidence is generally inadmissible, a number of exceptions have been recognized over the years. These were later codified in section B of rule 404. These include motive, opportunity, intent, preparation, plan, identity and absence of mistake or accident.
Evidence offered under one of these exceptions must still be analyzed to determine whether the probative value outweights the prejudicial effect of the evidence. Rule 403. Because a genuine issue can usually not be identified until after the defense presented its case, 404(b) evidence is typically offered in rebuttal.
