A single judge of Kerala High Court held as follows.

From Para 6,

6. True, section 397 of the Code confers concurrent jurisdiction to the High Court as well as the Sessions Court to call for and examine the records of any proceedings before an inferior criminal court situated within its local jurisdiction for the purpose of satisfying itself as to the correctness, legality or propriety of any finding, sentence or order rendered in such proceedings. When the power of revision is concurrent, it may not be illegal for a person to approach the High Court instead of the Sessions Court with a prayer for revision of an order. A Full Bench of this Court considered in Sivan Pillai v. Rajamohan and others [1978 KLT 223] the question whether a revision, where it is maintainable in view of the provisions of Section 397(1) of the Code, in the High Court as well as a Sessions Court, should be pinned down to the Sessions Court. The view taken by the majority is that the salutary principle that where concurrent jurisdiction is conferred on two fora, the lower forum should be exhausted first has to be given a go by in view of the specific provision conferring jurisdiction by Section 397(1) of the Code both on the High Court and the Sessions Courts. That is the law. But
propriety demands the aggrieved, as far as possible, to first invoke the jurisdiction of the Sessions Court. It is apposite to approach the Sessions Court first for another reason also. That, the parties might be located in the Sessions Division concerned. In a revision petition any order, which causes prejudice to the accused, can be passed, in view of Section 401(2) of the Code, only after giving notice to him. Where the accused resides in a far away Sessions Division he has to be drawn to the High Court as though the matter can be heard and decided by the Sessions Court concerned without  causing such an inconvenience. Therefore, it is just and appropriate for a party to invoke the jurisdiction of the Court of Sessions first, where the  revision is possible by both the High Court and the Sessions Court, albeit there is no bar for the High Court to entertain the revision filed without exhaustion of the lower forum.
