This blog compares written and unwritten constitutions, exploring their features, advantages, and limitations, with examples from India, the UK, and other nations.

Written vs. Unwritten Constitution

Introduction

A constitution is the fundamental law that sets out how a country is governed. It establishes the framework for political institutions, distributes power among them, and ensures citizens’ rights. Constitutions can be either written or unwritten, and understanding the distinction is essential for political science, comparative politics, and public administration.


1. What is a Written Constitution?

Definition:

A written constitution is a single, codified document or a collection of legal texts that systematically outlines the structure of the government, the distribution of powers, and the rights of citizens.

Key Features:

  • Codified in a formal document

  • Deliberately enacted by a constituent assembly or similar authority

  • Considered supreme law of the land

  • Can usually only be amended by a special process (not ordinary legislation)

Examples:

  • India (1950) – The longest written constitution in the world

  • United States (1789) – The oldest functioning written constitution

  • Germany – Basic Law of 1949


2. What is an Unwritten Constitution?

Definition:

An unwritten constitution is not contained in a single legal document. Instead, it consists of multiple sources like statutes, judicial decisions, conventions, and customs.

Key Features:

  • Not codified in one document

  • Evolves over time, based on traditions, practices, and judicial rulings

  • Often more flexible and adaptable

  • Relies heavily on precedents and conventions

Examples:

  • United Kingdom – The classic example

  • New Zealand

  • Israel (partially written, heavily reliant on statutes and customs)


3. Differences Between Written and Unwritten Constitutions

Feature

Written Constitution

Unwritten Constitution

Codification

Codified in a single document

Not codified; derived from various sources

Source

Drafted by a constituent body

Based on customs, conventions, statutes

Amendment

Rigid; requires special procedure

Flexible; can evolve gradually

Clarity

Provides legal certainty

Can be ambiguous or open to interpretation

Judicial Review

Stronger; courts can invalidate laws

Examples

India, USA, France

UK, New Zealand


4. Merits and Demerits of Written Constitution

Merits:

  • Clarity and precision in governance

  • Protects fundamental rights more explicitly

  • Legal supremacy is clear

  • Offers a blueprint for all organs of the state

Demerits:

  • Often rigid, making changes slow

  • Might not adapt well to changing circumstances

  • Judicial interpretation can become too dominant


5. Merits and Demerits of Unwritten Constitution

Merits:

  • Flexibility and adaptability to changing political contexts

  • Evolves through democratic practices and traditions

  • Encourages organic growth of the political system

Demerits:

  • Lack of clarity can lead to misuse

  • Rights may not be clearly spelled out

  • Over-dependence on conventions may cause constitutional uncertainty


6. Which is Better?

It depends on the context and political culture of the country:

  • For newly independent or diverse nations, a written constitution offers structure and stability.

  • In stable democracies with a long legal tradition (like the UK), an unwritten constitution can work effectively.

India, due to its diversity and colonial legacy, chose a written constitution to ensure clarity, unity, and a strong foundation for democracy.


7. The Indian Constitution: A Case Study in Written Constitution

India’s Constitution is a classic example of a written constitution:

  • Drafted by a Constituent Assembly

  • Adopted in 1950

  • Contains 448 Articles, 12 Schedules, and numerous Amendments

  • Ensures fundamental rights, directive principles, and detailed governance structures

However, over time, conventions and judicial interpretations have also shaped its functioning, showing a blend of written and unwritten features.


8. The UK Constitution: A Case Study in Unwritten Constitution

The UK has:

  • No single codified document

  • A constitution based on:

    • Statutes (e.g., Magna Carta, Bill of Rights)

    • Judicial decisions

    • Conventions (e.g., Prime Minister must be from the majority party)

  • Flexibility allows quick reforms (like the Fixed-term Parliaments Act)

Despite being unwritten, it is one of the world’s most stable and effective constitutions.
