Para. 28: “This rule, that proof rests on he who asserts the affirmative and not on he who denies, “is an ancient rule founded on consideration of common sense and should not be departed from without strong reasons”, according to Lord Maugham in the case of Constantine Line v. Imperial Smelting Corporation (1942) A.C. 154 at p. 174. In assuming the burden of proof, it means that if at the end of the day the plaintiff has not produced evidence to discharge the burden on him he must lose the decision on the particular issue. However, being a civil matter the burden that the plaintiff assumes is one of a proof by preponderance of probability or sometimes called reasonable probability.”
