Social Science (087) — AI-generated practice question

The Union Government's decision cannot be prevented by Rajasthan because defence, foreign affairs, banking, communications, and currency — matters of national importance — fall under the Union List, on which only the Union Government has the authority to make laws. State governments have no jurisdiction over Union List subjects; their legislative power is limited to the State List. Since nuclear policy (defence) is a Union List subject, Rajasthan has no constitutional power to stop the Centre.

The Union List reflects the principle of uniform national policy because these subjects — such as defence and currency — require the same rules across the entire country. If each state made its own laws on these matters, it would create chaos and threaten national unity and security.

• Examiners expect you to name the Union List and state that only the Union Government can legislate on it — this is the core legal reason.
• Link to the "uniform national policy" principle using the textbook's own language and examples (defence, currency, etc.).
• The Pokharan/nuclear test example from the textbook directly supports this question — use it confidently.
• Avoid writing about the Concurrent List or State List unless asked; stay focused on what the question asks.
