Certain documents deemed duplicates

A reproduction of a document acquired from the employment of a system of microphotography, optical discs or computerized techniques which system does not permit additions, deletions or changes to the record of the original document contained within the system shall be deemed to be a duplicate for purposes of admission into evidence in the courts of this state. A reproduction deemed a duplicate pursuant to the provisions of this section shall be authenticated by competent testimony or by an attestation which shall recite the type of recording system employed, that such system does not permit additions, deletions or changes to the record and that the attestant has actual knowledge of the aforementioned facts. The provisions of this section shall be construed to provide an additional method of qualifying original writings or recordings and duplicates thereof as admissible in evidence, and shall not replace or derogate any other methods set forth elsewhere in this code or provided for in the West Virginia rules of evidence as adopted by the Supreme Court of Appeals.
