Evidence Act, Section 45 -  Expert witness - DNA test and  Superimposition test - - Opinion evidence  - One cannot lose sight of the fact that DNA evidence is also in the nature of opinion evidence as envisaged in Section 45 of the Indian Evidence Act - Undoubtedly, an expert giving evidence before the Court plays a crucial role, especially since the entire purpose and object of opinion evidence is to aid the Court in forming its opinion on questions concerning foreign law, science, art, etc., on which the Court might not have the technical expertise to form an opinion on its own - In criminal cases, such questions may pertain to aspects such as ballistics, fingerprint matching, handwriting comparison, and even DNA testing or superimposition techniques, as seen in the instant case - Like all other opinion evidence, the probative value accorded to DNA evidence also varies from case to case, depending on facts and circumstances and the weight accorded to other evidence on record, whether contrary or corroborative - This is all the more important to remember, given that even though the accuracy of DNA evidence may be increasing with the advancement of science and technology with every passing day, thereby making it more and more reliable, we have not yet reached a juncture where it may be said to be infallible - Thus, it cannot be said that the absence of DNA evidence would lead to an adverse inference against a party, especially in the presence of other cogent and reliable evidence on record in favour of such party - Criminal Trial  - IPC,  S. 302, 364 and 201. 2019 SCeJournal 471
