transcript of examination.

1. When the transcript and record of the examination on commission are received by the superior court which issued the commission, they must be filed therewith if such court be the trial court, and, if not, transmitted to the trial court. A copy of the transcript must be delivered by the trial court to each party.

2. Upon the trial of the action, either party may, subject to the provisions of subdivision three, introduce and read into evidence the transcript or that portion thereof containing the testimony of a witness examined on the commission.

3. At any time prior to the introduction of such evidence, the trial court may examine the transcript and, upon according both parties opportunity to be heard and to register objections, may exclude and strike therefrom irrelevant, incompetent or otherwise inadmissible testimony. While the transcript or any portion thereof is being read into evidence at the trial by a party, the other party may register any objection or protest thereto that he would be entitled to register were the witness testifying in person, regardless of whether such protest has previously been raised and passed upon by the court, and the court must rule thereon.
