legal analysis of the "original document rule" in cyber space

the “original document rule” provides when a document is adduced as substantive evidence of its contents. due to the nature of electronic document which is difficult to class as original, the said rule has been abolished by many jurisdictions. the uncitral model law as well as iranian electronic commerce law pre-empts this by making it clear that a data message shall not be denied admissibility as evidence on the ground that it is not in its original form.
