Indian Evidence Act, 1872
167. No new trial for improper admission or rejection or
evidence
This improper
admission or rejection of evidence shall not be ground of itself for a new
trial or reversal of any decision in any case, if it shall appear to the court
before which such objection is raised that, independently of the evidence
objected to and admitted, there was sufficient evidence to justify the
decision, or that, if the rejected evidence had been received, it ought not to
have varied the decision.
