Admissibility of computer evidence: electronic reproductions are treated as documents when statutory conditions and official certificates are satisfied. Microfilms, facsimile copies, computer printouts and electronically stored information (including hard copies) are deemed documents and admissible as evidence of original contents if conditions for computer printouts are met: regular use of the computer for relevant activities, regular supply of the relevant information, proper operation of the computer during the material period (or any malfunction not affecting accuracy), and that the printout's contents derive from information so supplied. Multiple computers used successively are treated as a single computer. A certificate by a responsible official describing production and addressing these matters is admissible evidence.
