The officer-in-charge before whom any deposition or declaration is taken is entitled to certify on it that the witness was accordingly sworn by him and that the declaration is a factual and accurate record of the testimony given by the witness. He must seal the deposition conjointly with any papers produced by the witness and the notice of deposition or stipulation in an envelope authorized with the title of the election case and marked “Deposition of (name of witness)” and must within thirty days after completion of the witness’ testimony, file it with the Clerk of the office. After deposition is filed, the officer is supposed to inform the parties of its filing. Subsequently, after the payment of realistic charge, the officer duly furnishes a copy of deposition to any party or the deponent or testifier.
