The Superior Court shall grant the writ of recordari only upon petition specifying the grounds of the application. The petition shall be verified and the writ may be granted with or without notice. When notice is given the petition shall be heard upon answer thereto duly verified and upon the affidavits and other evidence offered by the parties. The decision thereupon shall be final, subject to appeal as in other cases. If the petition is granted without notice, the petitioner shall give an undertaking for costs and for the writ of supersedeas, if prayed for. In such case the writ of recordari shall be made returnable to the session of the Superior Court of the county in which the judgment or proceeding complained of was granted, and ten days’ written notice shall be given to the adverse party before the session of the court to which the writ is returnable. At that session the respondent may move to dismiss, or may answer the writ, and the answer shall be verified. After hearing the application upon the petition, answer, affidavits, and evidence offered, the court shall dismiss it or order it placed on the trial docket.

In proper cases and in like manner, the court may grant the writ of certiorari. When a diminution of the record is suggested and the record is manifestly imperfect, the court may grant the writ upon motion in the cause.
