Indian Evidence Act, 1872
45. Opinions of experts
When the Court has to
form and opinion upon a point of foreign law or of science or art, or as to
identity of handwriting 30[ or finger impressions], the opinions
upon that point of persons specially skilled in such foreign law, science or
art, 31[ or in questions as to identity of handwriting ] 30[
or finger impressions ] are relevant facts.
Such persons are
called experts.
Illustrations
(a) The question is,
whether the death of A was caused by poison.
The opinions of
experts as to the symptoms produced by the poison by which A is supposed to
have died, are relevant.
(b) The question is,
whether A, at the time of doing a certain act, was, by reason of unsoundness of
mind, incapable of knowing the nature of the Act, or that he was doing what was
either wrong or contrary to law.
The opinions of
experts upon the question whether the symptoms exhibited by A commonly show
unsoundness of mind, and whether such unsoundness of mind usually renders
persons incapable of knowing the nature of the acts which they do, or of
knowing that what they do is either wrong or contrary to law, are relevant.
(c) The question is,
whether a certain document was written by A. Another document is produced which
is proved or admitted to have been written by A.
The opinions of
experts on the question whether the two documents were written by the same
person or by different persons are relevant.
