Rebuttal Witness Law and Legal Definition

Rebuttal Witness is a witness who is called to rebut testimony already presented. For example in a murder case the defence might call a character witness to provide evidence that the accused was a mild mannered nice guy. A rebuttal witness might be called by the prosecution to provide contradictory evidence of the accused's character and might testify that the person was violent, bad tempered or abusive. Experts are often called to testify for the prosecution and the defence will then often call other (rebuttal) experts who might have reached a different conclusion.
