Primary Evidence

Definition

The best available form of a document, ordinarily the original itself. Under BSA 2023, electronic records certified under Section 63 are treated as primary evidence. Most legal systems give preference to primary evidence and require justification before a copy is substituted.

Common questions

When can secondary evidence be admitted in place of primary evidence?+

Only where the original is shown to be lost, destroyed, in the possession of the opposing party who refuses to produce it, or otherwise unavailable for a recognised reason; the party seeking to rely on the copy carries the burden of establishing that exception.

Why do electronic records need a certificate to be treated as primary evidence?+

A digital file is easy to alter without leaving an obvious trace, so a certificate under provisions like Section 63 attests to how the record was generated and stored, giving the court a basis to treat the electronic output with the same confidence normally reserved for an original document.
