Evidence of public servants permits deposition by a successor officer when original is unavailable, subject to dispute and remote testimony. When a report by a public servant, scientific expert or medical officer is tendered as evidence and the original preparer is transferred, retired, deceased, untraceable, incapable of deposition, or their attendance would cause delay, the Court shall secure deposition from the officer then holding that post as successor. No such officer shall be summoned unless the report is disputed by a party, and the successor's deposition may be allowed through audio video electronic means.
