"22. The Revisional Court is empowered to exercise all the powers conferred on the Appellate Court by virtue of the provisions contained in Section 401CrPC. Section 401CrPC is a provision enabling the High Court to exercise all powers of an Appellate Court, if necessary, in aid of power of superintendence or supervision as a part of power of revision conferred on the High Court or the Sessions Court. Section 397CrPC confers power on the High Court or Sessions Court, as the case may be, "for the purpose of satisfying itself or himself as to the correctness, legality or propriety of any finding, sentence or order, recorded or passed, and as to the regularity of any proceeding of such inferior court." It is for the above purpose, if necessary, the High Court or Sessions Court can exercise all appellate powers. Section 401CrPC conferring powers of an appellate court on the revisional court is with the above limited purpose. The provisions contained in Section 395to Section 401CrPC, read together, do not indicate that the revisional power of the High Court can be exercised as a second appellate power."
