Rule 61. Harmless error.

No error in either the admission or exclusion of evidence and no error or defect in any ruling or order or in anything done or omitted by any of the parties is ground for granting a new trial or for setting aside a verdict or for vacating, modifying, or otherwise disturbing a judgment or order, unless refusal to take such action amounts to the denial of a substantial right. (1967, c. 954, s. 1.)
