What is Constitution?

A Constitution is a foundational set of legal principles or rules that defines the framework of a government. It acts as the supreme law that governs the state and its citizens. It also regulates the interaction between the legislative, executive, and judicial branches, serving as a blueprint for political order and stability in the country. This guide covers what is constitutional law, its definition, key features, scope, career paths, and landmark case examples for anyone seeking a clear understanding of the field.

Definition of Constitutional Law

Constitutional law refers to the branch of law that deals with the rules, principles, and doctrines found within a constitution. It encompasses the interpretation of constitutional provisions, examining the powers of the government, and enforcing fundamental rights.

Key Features of Constitutional Law

  • Establishes the structure for the organs of government (parliament, executive, judiciary) and their functions.
  • Defines the fundamental rights and duties of citizens and the state's obligations towards them.
  • Protects the rights of citizens often through judicial review.
  • States the powers of the government and sets limits to ensure actions remain within the law.
  • Deals with the distribution and separation of power between the Union and State governments.

Overview of Constitutional Law in India

Indian constitutional law is the law derived from India's Constitution. It is a comprehensive, written document governing India as a sovereign, socialist, secular, democratic republic. It serves as the highest law over all other statutes, from which Parliament and State Legislatures derive their legislative authority. The Constitution of India was adopted on 26 November 1949 and came into force on 26 January 1950.

The constitution of India contains several key features that define its structure and operation. Major features include:

  • It is the longest written constitution in the world
  • It has features borrowed from various constitutions, including the Government of India Act 1935, the UK, the US, Ireland, and Canada.
  • It establishes a federal system with a power division between the Union and State governments.
  • Features a parliamentary form of government with an executive responsible to the legislature.
  • Balances parliament's law-making power with judicial review, fundamental rights, and the basic structure, so no law overrides the Constitution.
  • Emphasises equality before the law and procedure established under Article 21.
  • Includes an independent judiciary separate from the executive and legislature.

Scope of Constitutional Law in India

The scope of constitutional law is vast, covering the structure and powers of government, the relationship between citizens and the state, fundamental rights, and the limits of state authority. It resolves conflicts between governmental branches and ensures accountability. Constitutional law also incorporates and provides mechanisms to protect the rights of citizens.

Constitutional Law as a Career

Why pursue constitutional law as a career? The main purpose of constitutional law is to safeguard individuals' rights by upholding democratic principles. A course in constitutional law teaches about the nation's fundamental laws, principles, key court judgments, and global comparisons. Pursuing constitutional law can help aspiring judges, lawyers, civil servants, students, or citizens contribute to shaping laws and impacting society.

In India, a study of constitutional law is offered as a core part of law programmes like LLB   and LLM. Constitutional law is also offered as certifications, diplomas and online courses by platforms like SWAYAM and NPTEL. Opportunities after constitutional law include roles in litigation, corporate counsel, public prosecutor, judicial services, legal advisor, academia and policy-making, depending on the type of course taken.

Syllabus of Constitutional Law

Landmark Cases and Examples

Landmark cases in Indian constitutional law have shaped the interpretation of the Constitution, particularly through the Supreme Court's rulings on fundamental rights, federalism, and the basic structure doctrine. Below are some key case examples of constitutional law in India:

  1. Kesavananda Bharati vs. State of Kerala (1973): This case established the basic structure doctrine by holding that Parliament's power to amend the Constitution is not unlimited. It imposed restrictions on Parliament’s power under Article 368.
  2. Golaknath vs. State of Punjab (1967): The case ruled that Parliament cannot amend fundamental rights under Part III, treating them as transcendental, though later refined in subsequent judgments.
  3. Minerva Mills vs. Union of India (1980): The case reaffirmed judicial review and the Constitution's supremacy as part of the basic structure according to the 42nd Amendment.​
  4. Indira Nehru Gandhi vs. Raj Narain (1975): The verdict in this case led to striking down parts of the 39th constitutional amendment for violating the basic structure, reinforcing judicial review over elections.​

These examples of constitutional law demonstrate how fundamental rights are protected in India using the democratic framework.

What are Constitutional Rights?

Constitutional rights are legally established rights of individuals protected by the government. They are protections granted to individuals under the constitution of a nation. In India, fundamental rights are a subset of constitutional rights guaranteed under Part III of the Constitution.

The constitutional rights include:

  • Freedom of Speech and Expression
  • Right to Life & Liberty (Article 21)
  • Right to Equality (Articles 14-18)
  • Freedom of Religion (Articles 25-28)
  • Right to Privacy

In the Indian Constitution, the Right to Equality is Articles 14-18, Freedom of Religion is Articles 25-28, while the Right to Property (originally Article 31) is now a legal right under Article 300A, and the Right to Privacy is implicit in Article 21 (Right to Life & Liberty).

Conclusion

Constitutional law shapes a society's political and social fabric. Understanding what constitutional law is, its pivotal role, and key features is crucial for safeguarding individual rights. It also strengthens an individual's understanding of the country's legal and governance framework. Grasping these principles helps citizens to engage critically with constitutional issues and uphold the rule of law in a democracy.
