Rule 1004. Admissibility of Other Evidence of Contents

The original is not required, and other evidence of the contents of a writing,
recording, or photograph is admissible if–

(1) Originals lost or destroyed. All originals are lost or have been destroyed,
unless the proponent lost or destroyed them in bad faith; or

(2) Original not obtainable. No original can be obtained by any available
judicial process or procedure; or

(3) Original in possession of opponent. At a time when an original was under the
control of the party against whom offered, the party was put on notice, by the
pleadings or otherwise, that the contents would be a subject of proof at the
hearing, and the party does not produce the original at the hearing; or

(4) Collateral matters. The writing, recording, or photograph is not closely
related to a controlling issue.
