best evidence

Proof beyond doubt

Best evidence is the most reliable form of proof available for establishing a fact, particularly in legal contexts.

The best evidence rule requires that original documents be produced rather than copies or descriptions when the contents are at issue: The court demanded the original contract as best evidence.

More broadly, best evidence means the strongest support for any claim—direct observation over hearsay, primary sources over summaries.
