Section 251: Wrongful admission or exclusion of evidence.

1 The wrongful admission of evidence shall not of itself be a ground for the reversal of any decision in any case where it appears to the court on appeal that the evidence so admitted cannot reasonably be held to have affected the decision and that such decision would have been the same if such evidence had not been admitted.

2 The wrongful exclusion of evidence shall not of itself be a ground for the reversal of any decision in any case if it appears to the court on appeal that had the evidence excluded been admitted it may reasonably be held that the decision would have been the same.

3 In this section the term "decision" includes a judgment, order, finding or verdict.
