Definition of Rebuttal. Strictly interpreted, rebuttal refers to an attempt to disapprove, contradict or argue to overcome an opposing reasoning or evidence by introducing another reasoning and evidence to destroy the effect of the previous one.
In law, special rules apply to rebuttal. Rebuttal evidence or rebuttal witnesses must be confined solely to the subject matter of the evidence rebutted. New evidence on other subjects may not be brought in rebuttal. However, rebuttal is one of the few vehicles whereby a party may introduce surprise evidence or witnesses.
