Section 61 of Evidence Act "Proof of contents of documents"
The contents of documents may be proved either by primary or by secondary evidence.
Section 62 of Evidence Act "Primary evidence"
Primary evidence means the documents itself produced for the
inspection of the Court.
Explanation 1 Where a document is executed in several parts, each part is primary evidence of the document :
Where a document is executed in counterpart, each counterpart being executed by one or some of the parties only, each counterpart is primary evidence as against the parties executing it.
Explanation 2- Where a number of documents are all made
by one uniform process, as in the case of printing,
lithography, or photography, each is primary evidence of the
contents of the rest ; but, where they are all copies of a
common original, they are not primary evidence of the
contents of the original.
A person is shown to have been in possession of a number of placards, all printed at one time from one original. Any one of the placards is primary evidence of the contents of any other, but no one of them is primary evidence of the contents of the original.
