Section 86: Primary evidence.

1 Primary evidence means the document itself produced for the inspection of the court.

2 Where a document has been executed in several parts, each part shall be primary evidence of the document.

3 Where a document has been executed in counterpart, each counterpart being executed by one or some of the parties only, each counterpart shall be primary evidence as against the parties executing it.

4 Where a number of documents have all been made by one uniform process, as in the case of printing, lithography, photography, computer or other electronic or mechanical process, each shall be primary evidence of the contents of the rest; but where they are all copies of a common original, they shall not be primary evidence of the contents of the original.
