Concept:
The Supreme Court of India has three types of jurisdictions: Original, Appellate, and Advisory.
Step 1: Defining Advisory Jurisdiction.
The President can consult the Supreme Court on questions of law or fact.
This is often used for matters of great public importance.
The Supreme Court is not bound to give an opinion (except on pre-constitutional treaties), and the President is not bound to follow it.
Step 2: Identifying the specific Article.
This power is explicitly mentioned in
Article 143.
Commonly known as the "Presidential Reference."
