W.Va. R. Civ. P. 61
As amended through January 31, 2024
Unless justice requires otherwise, no error in admitting or excluding evidence or any other error by the court or a party-is 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 shall disregard all errors and defects that do not affect any party's substantial rights.
