"The federal supremacy is the fundamental element of the system of governance in India." Explain.

"Federal Supremacy is a Fundamental Element in India":

While India's Constitution establishes a dual polity (Union and States), the constitutional architecture deliberately embeds "Federal Supremacy" to safeguard national integration.

• Legislative Precedence (Article 246 & 254): In case of conflict between Union and State laws on Concurrent List subjects, the Union law prevails over State law.
• Residuary Powers (Article 248): Unlike the US, residuary powers to legislate on unlisted subjects vest exclusively with the Union Parliament.
• Parliamentary Override on State List: Parliament can legislate on State List subjects under national interest (Art. 249), during National Emergency (Art. 250), with States' consent (Art. 252), or to implement international treaties (Art. 253).
• Executive and Administrative Direction (Articles 256, 257, 365): Centre issues binding executive directives to States; non-compliance triggers Article 356 (President's Rule).
• Single Integrated Judiciary & All India Services: Uniform judicial hierarchy and IAS/IPS cadre maintain national administrative standards.

Conclusion: As Dr. B.R. Ambedkar asserted, India is an indestructible Union of destructible States, making federal supremacy the linchpin of constitutional unity.
