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, that party was put on notice, by the pleadings or otherwise, that the contents would be a subject of proof at the hearing, and that 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.
