Under Section 62, what is considered primary evidence? 

Section 62 defines "Primary Evidence" as the document itself produced for the court's inspection. It is considered the best and most authentic form of evidence for proving the contents of a document. The Act gives primary importance to the original document over any copy or reproduction, unless exceptions under secondary evidence apply. This provision ensures accuracy and trustworthiness in documentary evidence. Only where the original is unavailable under justified grounds can secondary evidence be introduced, following due procedure.
