The admissibility of medical expert testimony in India is governed by the Indian Evidence Act, which provides the legal framework for the submission and evaluation of evidence in courts. Under this Act, medical experts are allowed to present their opinions to assist the court in understanding complex medical facts. Sections like 45 and 45A specifically deal with expert opinions, recognizing the importance of expert medical testimony in cases involving medical issues. This ensures that the court relies on qualified medical professionals to interpret clinical findings and provide credible opinions, making the Indian Evidence Act essential for such proceedings.
