N.Y. Civil Practice Law & Rules § 4539: Reproductions of original

Rule 4539. Reproductions of original. (a) If any business,

institution, or member of a profession or calling, in the regular course

of business or activity has made, kept or recorded any writing, entry,

print or representation and in the regular course of business has

recorded, copied, or reproduced it by any process, including

reproduction, which accurately reproduces or forms a durable medium for

reproducing the original, such reproduction, when satisfactorily

identified, is as admissible in evidence as the original, whether the

original is in existence or not, and an enlargement or facsimile of such

reproduction is admissible in evidence if the original reproduction is

in existence and available for inspection under direction of the court.

The introduction of a reproduction does not preclude admission of the

original.

(b) A reproduction created by any process which stores an image of any

writing, entry, print or representation and which does not permit

additions, deletions, or changes without leaving a record of such

additions, deletions, or changes, when authenticated by competent

testimony or affidavit which shall include the manner or method by which

tampering or degradation of the reproduction is prevented, shall be as

admissible in evidence as the original.
