Opinions of experts

AI Assist

Summary

When the court must form an opinion on foreign law, science, art, handwriting, finger impressions or any technical field, the views of persons specially skilled in that field are relevant facts and called experts. Their opinions on symptoms, causes, identity of handwriting, or technical electronic information may be relied on. For computer or electronic data, the Examiner of Electronic Evidence (under the IT Act) is an expert whose opinion is relevant.

Example

Priya’s neighbour dies and doctors suspect poisoning. The court admits a forensic toxicologist’s opinion on the symptoms and whether they match poison as a relevant expert fact. That opinion will help decide if the death was caused by poison.

Bare Act

Enacted text

(1) When the Court has to form an opinion upon a point of foreign law or of science or art, or any other field, 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 any other field, or in questions as to identity of handwriting or finger impressions are relevant facts and 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.

(2) When in a proceeding, the court has to form an opinion on any matter relating to any information transmitted or stored in any computer resource or any other electronic or digital form, the opinion of the Examiner of Electronic Evidence referred to in section 79A of the Information Technology Act, 2000, is a relevant fact.

Explanation.-For the purposes of this sub-section, an Examiner of Electronic Evidence shall be an expert.
