17. The decision in Murari Lal4 and Lalit Popli5 should not be construed as laying a proposition that the Court is bound to compare the disputed and admitted finger impressions and record a finding thereon, irrespective of the condition of the disputed finger impression. When there is a positive denial by the person who is said to have affixed his finger impression and where the finger impression in the disputed document is vague or smudgy or not clear, making it difficult for comparison, the Court should hesitate to venture a decision based on its own comparison of the disputed and admitted finger impressions. Further even in cases where the Court is constrained to take up such comparison, it should make a thorough study, if necessary with the assistance of Counsel, to ascertain the characteristics, similarities and dissimilarities. Necessarily, the judgment should contain the reasons for any conclusion based on comparison of the thumb impression, if it chooses to record a finding thereon. The Court should avoid reaching conclusions based on a mere casual or routine glance or perusal”.
