Introduction

An ‘expert’ is defined as a person who possesses special knowledge, skill, or experience in any particular field under section 45 of the Indian Evidence Act.

Qualifications of the expert, the relevance of their expertise to the case, the method used to arrive at the opinion, and the reliability of the facts upon which the opinion is based are considered before taking the expert opinion.

matters which is beyond the understanding of a layman. Expert Opinion can play a very important role in cases involving medical, scientific, forensic, or technical cases.
