Ariz. R. Civ. P. 61
As amended through August 22, 2024
Unless justice requires otherwise, an error in admitting or excluding evidence-or any other error by the court or a party-is not grounds 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 errors and defects that do not affect any party's substantial rights.
