Under what condition can a duplicate document be admitted?

A duplicate document can be admitted primarily when there are no questions regarding the authenticity of the original document. This principle stems from the rules of evidence, specifically regarding the admissibility of duplicates, which offers a practical solution to dealing with evidence without needing the original. If the original document's authenticity is uncontested, the duplicate serves as a reliable substitute and meets the legal requirements for admission.

In cases where the original document is lost, or its contents are not in dispute, the admissibility of a duplicate might still hinge on whether authenticity is established. The consideration of convenience for the court may factor into procedural decisions, but it does not satisfy the necessary legal standard for admitting a duplicate. Hence, the clarity surrounding the original's authenticity is pivotal.
