Harmless Error

Unless justice requires otherwise, no error in admitting or ex- cluding evidence—or any other error by the court or a party—is ground for granting a new trial, for setting aside a verdict, or for vacating, modifying, or otherwise disturbing a judgment or order. At every stage of the proceeding, the court must disregard all er- rors and defects that do not affect any party’s substantial rights. (As amended Apr. 30, 2007, eff. Dec. 1, 2007.)
