Recently I had occasion to read the judgment in the case of Dharambir v. Central Bureau of Investigation [cited as 148 (2008) DLT 289]. The case concerns prosecution of several accused on the basis of intercepted telephone conversations. These intercepted communications were stored on hard disks out of which CD’s were made subsequently. These CD’s contained relevant conversations out of the entire conversations contained on the hard disks. The prosecution sought to rely upon these CD’s as evidence against the accused. The judgment arises out of the accused petition’s seeking a mirror image of the hard disk. The judgment is quite a watershed as it is the first Indian judgment which elaborately discusses the admissibility of electronic records and the evidentiary requirements under the Indian Evidence Act.
