Reading Time:

The concept of constitutional supremacy refers to the fundamental principle that the Constitution is the supreme law of the land, and any law, decree, or regulation that conflicts with it is deemed void. In countries that abide by this principle, the judiciary is empowered to review legislative and executive actions and strike them down if they contravene the Constitution.

1. Origins of Constitutional Supremacy:

The roots of this concept can be traced to social contract theories, where the state and its citizens enter an implicit or explicit agreement. The Constitution embodies this agreement and thus holds paramount importance over any other law.

2. Underlying Rationale:

The primary rationale behind the supremacy of the Constitution is to ensure:

  • Consistency in laws and policies
  • Protection of fundamental rights of citizens
  • Checks and balances on the powers of different arms of the government

3. The Role of Judiciary:

In countries that adhere to the doctrine of constitutional supremacy, the judiciary plays a pivotal role. Courts have the authority to interpret the Constitution and, in doing so, can declare legislative or executive actions unconstitutional. This process is often referred to as “judicial review.”

4. Constitutional Supremacy vs. Parliamentary Supremacy:

While countries like the USA, India, and South Africa follow the principle of constitutional supremacy, others, such as the UK, adhere to parliamentary supremacy. In the latter, the parliament’s laws are supreme, and there isn’t a codified constitution to challenge its decisions. The choice between these two models often reflects historical, political, and cultural factors unique to each nation.

5. Limitations and Challenges:

  • Overreach: One of the criticisms of constitutional supremacy, especially where judicial review is active, is the potential for judicial overreach. Detractors argue that unelected judges might have undue influence over public policy.
  • Rigidity: Another challenge is rigidity. Since the Constitution is supreme, making necessary changes can be cumbersome, requiring elaborate amendment procedures.

6. Constitutional Supremacy in Practice:

In practice, constitutional supremacy has often been a beacon of hope for those advocating for civil rights, justice, and the rule of law. It provides an avenue to challenge oppressive laws and brings about societal reforms.


  • In the USA, the landmark case of Brown v. Board of Education saw the Supreme Court striking down racial segregation in public schools, asserting the Constitution’s supremacy.
  • In India, the doctrine of the “basic structure” ensures that Parliament cannot amend the Constitution’s essential features, preserving the Constitution’s sanctity and supremacy.

7. Conclusion:

Constitutional supremacy is foundational in ensuring that a nation’s values, principles, and rights are preserved and protected against potential governmental overreach. While the principle has its critics and is not without challenges, it remains a cornerstone of democratic governance in many nations. The exact contours and implications of constitutional supremacy vary from one jurisdiction to another, but its essence remains the preservation of the rule of law and the protection of individual rights.
