Civil Procedure
Section 6. Harmless error. - No error in either the admission or the exclusion of evidence and no error or defect in any ruling or order or in anything done or omitted by the trial court or by any of the parties is ground for granting a new trial or for setting aside, modifying, or otherwise disturbing a judgment or order, unless refusal to take such action appears to the court inconsistent with substantial justice. The court at every stage of the proceeding must disregard any error or defect which does not affect the substantial rights of the parties. (5a)
