Section 45 Opinions of experts
When the Court has to form an opinion upon a point of foreign law or of science, or art, or as to identity of handwriting, [or finger impressions], the opinions upon that point of persons specially skilled in such foreign law, science or art, [or in questions as to identity of handwriting] [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.

Other provisions with similar text
The next closest matches, in order. Where a provision was split or merged, the answer is often more than one of these.
How this table was made, and what it is not
There is no official machine-readable correspondence between the Indian Evidence Act, 1872 and the Bharatiya Sakshya Adhiniyam, 2023. The Ministry published comparison charts for human readers; nothing exists that a computer can check. So this is not an official mapping and we do not present it as one.
What it measures is how alike the text of two provisions is. For each provision of the old enactment we compare its words against every provision of the new one and report the closest, with the score. That works here because the new codes are largely a renumbering rather than a rewrite: where a provision carried over near-verbatim the match is self-evidencing, and you can see it for yourself, because both texts are set out side by side on every entry.
Where the law genuinely changed, the score falls and the entry says no close match found rather than offering a guess. Those entries matter: they are where the reform actually did something.
Check before you cite. A high score means the words are alike, not that a court has held the provisions equivalent. For that, read both texts and the Gazette.
