Power of High Courts to issue certain writs
Notwithstanding anything in article 32, every High Court shall have power, throughout the territories in relation to which it exercises jurisdiction, to issue to any person or authority, including in appropriate cases, any Government, within those territories directions, orders or writs, including writs in the nature of habeas corpus, mandamus, prohibition, quo warranto and certiorari, or any of them, for the enforcement of any of the rights conferred by Part III and for any other purpose.
L. Chandra Kumar v. Union of India (1997). The power of High Courts under Article 226, and of the Supreme Court under Article 32, is part of the basic structure and cannot be ousted.
High Courts can issue writs to enforce fundamental rights and other legal duties.
