Section 166 of Evidence Act "Power of jury or assessors to put questions"

Section 167 of Evidence Act "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.
