Section 397 of the CrPC vests the court with the power to call for and examine the records of an inferior court for the purposes of satisfying itself as to the legality and regularity of any proceedings or order made in a case. The object of this provision is to set right a patent defect or an error of jurisdiction or law. There has to be a well-founded error and it may not be appropriate for the court to scrutinize the orders, which upon the face of it bears a token of careful consideration and appear to be in accordance with law. If one looks into the various judgments of this Court, it emerges that the revisional jurisdiction can be invoked where the decisions under challenge are grossly erroneous, there is no compliance with the provisions of law, and the finding recorded is based on no evidence, material evidence is ignored or judicial discretion is exercised arbitrarily or perversely. These are not exhaustive classes, but are merely indicative. Each case would have to be determined on its own merits.
