When the commission is ordered, the defendant must serve upon the district attorney, without delay, a copy of the interrogatories to be annexed thereto, with three (3) days notice of the time at which they will be presented to the court or judge. The district attorney may in like manner serve upon the defendant or his counsel cross-interrogatories, to be annexed to the commission, with like notice. In the interrogatories, either party may insert any question pertinent to the issue. When the interrogatories and cross-interrogatories are presented to the court or judge, according to the notice, the court or judge must modify the questions, so as to conform them to the rules of evidence, and must endorse upon them his alterations, and annex them to the commission. R.L.1910, § 6041.
