27.In disciplinary proceedings, disciplinary authority is
expected to consider the evidence and arrive at the conclusion of a
fact on pre-ponderance of probability. The test of “preponderance
of prohibition” has been very elegantly explained by the Hon'ble
Supreme Court in N.G.Dastane (Dr) Vs. S.Dastane (1975) 2 SCC
326 as follow:
“The normal rule which governs civil
proceedings is that a fact can be said to be
established if it is proved by a preponderance of
probabilities. This is for the reason that under the
Evidence Act, Section 3, a fact is said to be proved
when the court either believes it to exist or considers
its existence so probable that a prudent man ought,
under the circumstances of the particular case, to act
upon the supposition that it exists. The belief
regarding the existence of a fact may thus be
founded on a balance of probabilities. A prudent man
faced with conflicting probabilities concerning a fact-

exists, if on weighing the various probabilities he
finds that the preponderance is in favour of the
existence of the particular fact. As a prudent man, so
the court applies this test for finding whether a fact
in issue can be said to be proved. The first step in
this process is to fix the probabilities, the second to
weigh them, though the two may often intermingle.
The impossible is weeded out at the first stage, the
improbable at the second. Within the wide range of
probabilities the court has often a difficult choice to
make but it is this choice which ultimately
determines where the preponderance of probabilities
lies. Important issues like those which affect the
status of parties demand a closer scrutiny than those
like the loan on a promissory note: “the nature and
gravity of an issue necessarily determines the
manner of attaining reasonable satisfaction of the
truth of the issue [ Per Dixon, J. in Wright v. Wright,
(1948) 77 CLR 191, 210] ”; or as said by Lord
Denning, “the degree of probability depends on the
subject-matter.
