(A) Harmless Error. An error in the admission or the exclusion of evidence, an error in a ruling or order, or an error or defect in anything done or omitted by the court or by the parties is not ground for granting a new trial, for setting aside a verdict, or for vacating, modifying, or otherwise disturbing a judgment or order, unless refusal to take this action appears to the court inconsistent with substantial justice.
(B) Correction of Error by Other Judges. A judgment or order may be set aside or vacated, and a proceeding under a judgment or order may be stayed, only by the judge who entered the judgment or order, unless that judge is absent or unable to act. If the judge who entered the judgment or order is absent or unable to act, an order vacating or setting aside the judgment or order or staying proceedings under the judgment or order may be entered by a judge otherwise empowered to rule in the matter.
(C) Review of Findings by Trial Court. Findings of fact by the trial court may not be set aside unless clearly erroneous. In the application of this principle, regard shall be given to the special opportunity of the trial court to judge the credibility of the witnesses who appeared before it.
