Section 121 - Proof of facts.

A fact is said to be-

(a) "Proved" when, after considering the matters before it, the court either believes it to exist or considers its existence so probable that a prudent man ought, in the circumstances of the particular case, to act upon the supposition that it does exist;

(b) "disproved" when, after considering the matters before it, the court either believes that it does not exist or considers its non-existence so probable that a prudent man ought in the circumstances of the particular case, to act upon the supposition that it does not exist;

(c) "not proved" when it is neither proved nor disproved.
