In all appealable criminal cases where the convicted person desires to appeal from the sentence imposed, at the time of asking for an appeal he may also present the affidavits mentioned hereinafter in this section and obtain an order permitting him to prosecute his appeal without paying the costs, or furnishing security therefor.
The affidavits required above are:
The facts recited in these affidavits may be traversed by a summary rule by the district attorney. If this traverse is successful, the court shall rescind its order, and further order the convicted person to either pay the costs or to furnish security therefor within ten days. The failure to comply with this latter order shall operate a dismissal of the appeal.
This section does not apply to cases where the appellant is not now required by law to furnish an appeal bond or security for costs.
