How does the High Court protect the Fundamental Rights of individuals? What is meant by Revisory Jurisdiction of the High Courts?

The High Court enjoys original jurisdiction for the enforcement of Fundamental Rights guaranteed by the Constitution. All the High Courts are empowered to issue 'writs'. The writs that are issued are Habeas Corpus, Mandamus, Prohibition, Quo Warranto and Certiorari. These writs are greatly instrumental in the protection of Fundamental Rights of the citizens.

Revisory Jurisdiction means that the High Court can call for the record of a case which has been decided by a subordinate court. This is done because the High Court feels that the Subordinate Court has exercised a jurisdiction not vested in it or the latter has not followed proper procedure.
Therefore, the High Court can review the case and take appropriate action on it. This is known as the Revisory Jurisdiction of the High Court.
