Whenever any further proceedings are instituted before the trial court subsequent to the original trial and sentencing, excepting motions for new trial made within one year after the rendition of the verdict or the finding of the court, the court in the same action shall have jurisdiction to hear such matter only after due proof has been made that notice of such proceeding has been given to the attorney general at least ten days prior to such hearing.
