From a plain reading of Section 121A of the Act,under which revisional jurisdiction can be exercised,it would be clear that the High Court,while exercising such power is entitled to re-appreciate the evidence when it finds that the conclusion arrived at by the appellate authority runs contrary to the materials on record and when it finds that there is no evidence to support the conclusion of the appellate authority or when it finds that the reasons given by the appellate authority are absolutely perverse and cannot be supported by the evidence on record
