Rejection of evidence is:

As per s. 167. No new trial for improper admission or rejection of evidence .  –– The 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.
