Primary evidence: original documents, counterparts and electronic files serve as principal proof when produced for court inspection. Primary evidence treats the document produced for inspection as the principal proof of its contents; each executed part or counterpart is primary evidence for the document. Identical items produced by a uniform process are primary as to each other but not of a common original. Electronic and digital records stored in multiple files, transmissions, or automated storage instances, and recordings produced from proper custody, are treated as primary evidence unless disputed.
