DOCUMENTARY EVIDENCE

When books, records, papers or documents have been received in evidence, a copy thereof, or so much thereof as may be material or relevant, may in the discretion of the court be substituted therefor. After the decision of the court in any proceedings becomes final, the court may, upon motion of either party, permit the withdrawal by the party entitled thereto of originals of books, documents, and records, and of models, diagrams, and other exhibits introduced in evidence before the court; or the court may, on its own motion, make such disposition as it deems advisable.
