Like Article 32, Article 226 is a parallel provision for High Courts in states and allows one to institute similar writs in the High Courts for the enforcement of fundamental rights.
Here's an explanation of the five main writs:
Habeas Corpus: This writ is used to challenge unlawful detention. If you believe someone is being held illegally, a habeas corpus petition can be filed to bring them before the court. The court will then decide if the detention is lawful and order their release if not.
Mandamus: This writ is used to order a public official or a lower court to perform a legal duty they are neglecting. Essentially, it compels them to do something they are legally obligated to do.
Prohibition: This writ is the opposite of mandamus. It is used to prevent a public official or a lower court from exceeding their jurisdiction or acting illegally. It essentially prohibits them from doing something.
Certiorari: This writ is used to quash (cancel) an order passed by a lower court or tribunal if it is found to be illegal or improper. The higher court basically reviews the order and can overturn it if necessary.
Quo Warranto: This writ is used to challenge the right of a person to hold a public office. If someone is believed to be occupying a position illegally, a quo warranto petition can be filed to have them removed from the office. |
