California's "Best Evidence Rule," largely replaced by the more flexible Secondary Evidence Rule (Evidence Code §§ 1520-1523), historically required the original document, photo, or recording to prove its content, deeming copies or oral testimony as secondary evidence usually inadmissible unless the original was lost or unavailable through no fault of the party. Now, California generally allows secondary evidence (like duplicates or summaries) to prove content, but the court must exclude it if there's a genuine dispute over the original's terms or if admitting the secondary version would be unfair.
