“The scope and ambit of exercise of power and jurisdiction by a High Court under Article 227 of the Constitution of India is examined and explained in number of decisions of this Court. The exercise of power under this Article involves a duty on the High Court to keep inferior courts and tribunals within the bounds of their authority and to see that they do duty expected or required of them in a legal manner. The High Court is not vested with any unlimited prerogative to correct all kinds of hardship or wrong decisions made within the limits of the jurisdiction of the courts subordinate or tribunals. Exercise of this power and interfering with the orders of the courts or tribunal is restricted to cases of serious dereliction of duty and flagrant violation of fundamental principles of law or justice, where if High Court does not interfere, a grave injustice remains uncorrected. It is also well settled that the High Court while acting under this Article cannot exercise its power as an appellate court or substitute its own judgment in place of that of the subordinate court to correct an error, which is not apparent on the face of the record. The High Court can set aside or ignore the findings of facts of inferior court or tribunal, if there is no evidence at all to justify or the finding is so perverse, that no reasonable person can possibly come to such a conclusion, which the court or Tribunal has come to.”
