Constitutions are traditionally classified as either unitary or federal. In a unitary constitution, the powers of government are centralized within a single entity: the central government. In such states, provincial or state governments either do not exist at all, or if they do, they remain strictly subordinate to the center (e.g., the constitutions of the United Kingdom, Sri Lanka, and Singapore).

Conversely, a federal constitution entails a clear division of powers between the federal (union) government and the state governments, where both operate independently within their respective spheres (e.g., the constitutions of the United States, Canada, Australia, Malaysia, and Germany).

A long-standing constitutional debate centers on whether the Constitution of India is federal, unitary, or a hybrid of both—commonly referred to as quasi-federal. To arrive at an accurate determination, we must analyze the core characteristics of federalism and evaluate how effectively the Indian constitutional framework aligns with them.

II. Federal Principles Defined

According to Professor K.C. Wheare, the federal principle represents:

“The method of dividing powers so that the general [Union] and regional [State] governments are each within a sphere coordinate and independent.”[K.C. Wheare, Federal Government, 4th Edition, Oxford University Press, 1963]

Under this strict definition, the federal and regional governments must coexist as co-equals, neither being subordinate to the other. The Constitution of the United States is traditionally viewed as the archetype of a true federal constitution. Professor Wheare notes that if federal principles are predominant within a constitutional framework, the constitution is classified as federal; absolute compliance with every single characteristic is not an rigid prerequisite.

III. Essential Characteristics of a Federal Constitution

A federal constitution typically possesses several structural features, which also serve as the foundational merits of a federal system:

1. Distribution of Powers

Federalism fundamentally requires the distribution of state power among different coordinate bodies, each originating from and controlled by the constitution. Matters of national importance—such as defense, foreign affairs, railways, and posts and telegraphs—are entrusted to the Union. Conversely, matters of local concern are reserved for the states, including agriculture, police, local government, public health, and sanitation.

2. Supremacy of the Constitution

A federal state derives its legal existence entirely from its constitution. Consequently, every executive, legislative, and judicial power—whether exercised by the central or state government—is subordinate to and governed by the constitution.

3. Written Constitution

To maintain constitutional supremacy and provide institutional clarity, the constitution must be written (e.g., the American and Indian Constitutions). A written text minimizes structural misunderstandings, prevents boundary disputes between governments, and ensures systematic governance.

4. Rigidity

A natural consequence of constitutional supremacy is rigidity. A document that serves as the supreme law of the land cannot be altered by ordinary legislative processes. A rigid constitution requires a specialized, complex amendment procedure, ensuring that neither the center nor the states can unilaterally alter the federal balance.

5. Authority of the Courts (Independent Judiciary)

Legal supremacy requires an independent arbiter. Because actions by the center or states may occasionally overstep constitutional boundaries or infringe upon individual rights, an independent judiciary (the Supreme Court) is essential. The court serves as the final interpreter of the constitution and resolves jurisdictional conflicts between governance tiers.

6. Dual Polity

A federal system establishes a dual polity consisting of the Union at the center and states at the periphery, each endowed with sovereign powers to legislate and govern within their constitutionally demarcated spheres.

The Constitutional Dilemma of India

While the Indian Constitution possesses all these essential characteristics, several constitutional scholars hesitate to classify it as a purely federal system. They argue that specific provisions empower the Central Government to intervene in state matters, occasionally placing the states in a subordinate position.

Consequently, scholars like K.C. Wheare have termed the Indian Constitution "quasi-federal" or "unitary with federal features." Similarly, Sir Ivor Jennings famously characterized it as "a federation with a strong centralizing tendency."

IV. Unitary Features in the Indian Constitution

Critics and scholars point to several centralizing provisions within the Indian Constitution that deviate from classical federalism:

1. Appointment and Role of Governors

The Governor of a state is appointed and dismissed directly by the President of India (Articles 155 and 156) and remains answerable to the Union executive. While the Governor functions as the constitutional head of the state—normally acting on the advice of the State Council of Ministers—they can reserve certain state bills for the consideration and assent of the President. The President holds absolute veto power over such state legislations (Articles 200 and 201), as famously seen in the landmark case In Re Kerala Education Bill [AIR 1958 SC 95].

2. Parliament’s Power to Alter State Boundaries

Under Article 3 of the Constitution, the Parliament of India can unilaterally form new states, increase or diminish the territorial area of any state, and alter state boundaries or names. The territorial integrity of a state is not guaranteed under the Indian Constitution.

In Mullaperiyar Environmental Protection Forum v. Union of India [AIR 2006 SC 1428.] the Supreme Court affirmed that creating new states by altering territories and boundaries falls within the exclusive domain of Parliament under Articles 3 and 4. Parliament holds the supreme power to organize new states, divide land, water, and resources, distribute assets and liabilities, and manage legal obligations between predecessor and successor states.

3. Emergency Provisions

The Constitution provides for three types of emergencies:

i. National Emergency (Article 352): Triggered by war, external aggression, or armed rebellion.

ii. State Emergency / President's Rule (Article 356): Triggered by the failure of constitutional machinery in a state.

iii. Financial Emergency (Article 360): Triggered by threats to the financial stability or credit of India.

During an active emergency, the normal distribution of powers is suspended. Parliament gains the authority to legislate on any subject enumerated in the State List, transforming the operational nature of the polity from federal to entirely unitary. Historically, Article 356 has faced frequent criticism for being misused by central governments to dissolve democratically elected opposition state governments.

4. Single Citizenship

Unlike the United States, which features dual citizenship (of both the nation and the individual state), the Indian Constitution recognizes only a single, uniform citizenship: Citizenship of India.

5. Single, Unified Constitution

In India, a single constitutional document governs both the Union and the states. Conversely, in the American federal system, individual states retain the right to draft and adopt their own distinct state constitutions, provided they do not conflict with the federal constitution.

6. Integrated Election, Accounts, and Audit Machinery

While classical federations utilize separate, independent state-level election and audit bodies, India relies on centralized machinery. The Election Commission of India (Article 324) manages both central and state legislative elections, and the Comptroller and Auditor General of India (Article 148) audits the accounts of both the Union and state governments.

7. Distribution of Legislative Subjects and Residuary Powers

Article 246 and the Seventh Schedule divide legislative competencies into three distinct lists. Over time, constitutional amendments (such as the 42nd Amendment Act of 1976) have adjusted these lists. The updated distribution of subjects stands as follows:

List	Name	Current Number of Subjects	Original Number of Subjects
List I	Union List	100	97
List II	State List	61	66
List III	Concurrent List	52	47

Through various Constitutional Amendments (notably the 42nd Amendment Act), entry numbers have been preserved, but the actual count of functional subjects stands at 100 in the Union List, 61 in the State List, and 52 in the Concurrent List.

Furthermore, Article 248 vests all residuary powers (the authority to legislate on any matter not explicitly listed in any of the three lists, such as modern cyber laws) exclusively in the Union Parliament, tilting the constitutional balance further toward the center.

V. Merits and Demerits of Indian Federalism

A. Merits of Federalism

1. Unity in Diversity: In a vast nation characterized by deep linguistic, regional, and cultural diversity, federalism allows individual states to protect local cultures and distinct regional identities while remaining integrated within the nation.

2. Localized Governance: State governments are better positioned to address local grievances efficiently. Subjects of local significance—such as public order, police, and sanitation—remain properly managed under state jurisdiction.

3. Dual Governance Advantages: Citizens benefit from the dual layers of administration. While international commerce, national security, and communication are managed uniformly by the center, regional developments are custom-tailored by the states.

4. Inclusive Representation: A federal system ensures that regional minorities and distinct socio-cultural groups secure institutional representation in the governance of the nation.

B. Demerits of Federalism

1. Inter-Governmental Friction: Coordination between the center and states can become deeply challenging, particularly when opposing political parties hold power at different levels. This friction can disrupt fiscal transfers and strain cooperative federalism.

2. High Administrative Cost: Operating parallel legislative, executive, and administrative apparatuses at both the central and state levels makes federalism structurally more expensive than a unitary system.

3. Regionalism vs. Nationalism: Aggressive regional aspirations can occasionally overshadow national priorities, leading to secessionist movements or friction over shared resources like river waters.

4. Delays in Policy Implementation: Because policy execution often requires concurrent action from both central and state authorities, decision-making and legislative implementation can experience delays.

5. Lack of Legal Uniformity: Since states retain the autonomy to legislate within their jurisdiction, civil and administrative laws can vary across state borders, creating regional legal disparities.

VI. The Sarkaria Commission

A. Appointment and Objective

For the first few decades after independence, the same political party held power at both the center and across most states, which minimized major structural friction. However, by the late 1960s and 1970s, regional parties began forming governments in states like Kerala, Tamil Nadu, and West Bengal. These governments began demanding more fiscal autonomy and a thorough review of central interference.

In response to these growing federal tensions, the Government of India appointed a commission on March 24, 1983, headed by Justice R.S. Sarkaria, a retired judge of the Supreme Court, to examine and review the working of existing arrangements between the Union and the states.

B. Findings and Recommendations

The Commission submitted its comprehensive report in 1988. It firmly rejected demands to curtail central powers, stating that a robust center remains vital to preserving India's unity and integrity. It concluded that drastic structural changes to the Constitution were unnecessary, but it recommended several operational adjustments to improve relations:

Sharing of Corporate Taxes: The Commission recommended that corporate taxes and advertisement/broadcasting levies should be shared between the center and the states.

Retention of the Three Lists: It advised against transferring subjects from the Union List to the State or Concurrent Lists, and affirmed the center's authority to deploy armed forces. However, it suggested that the center should ideally consult the concerned state before deployment.

Supremacy of Parliament: It maintained that the legislative supremacy of Parliament under Articles 246 and 254 must remain intact.

Appointment of Governors: It recommended that the Prime Minister must meaningfully consult the Chief Minister of the respective state before the President appoints a Governor.

Judicious Use of Article 356: The Commission strongly argued against deleting Article 356 but insisted that it should be used as a last resort in rare circumstances. Before dissolving a state assembly, all possibilities of forming an alternative government must be thoroughly explored.

Consultation on Concurrent Subjects: The center should routinely consult state governments before drafting and passing legislations on subjects listed in the Concurrent List.

Inter-State Council: It strongly advocated for establishing a permanent Inter-State Council under Article 263 to resolve inter-state and center-state disputes.

C. Acceptance and Modern Legacy

The recommendations were gradually accepted across successive administrations. The National Front government established the Inter-State Council in 1990. Subsequent governments implemented several fiscal recommendations, including structural tax-sharing models that ultimately paved the way for modern bodies like the GST Council.

The principles laid down by the Sarkaria Commission—and later reinforced by the Supreme Court in the landmark S.R. Bommai v. Union of India (1994) judgment—have firmly established "Cooperative Federalism" as a part of the basic structure of the Indian Constitution.

VII. Conclusion

Dr. B.R. Ambedkar, the chief architect of the Drafting Committee, observed:

"Notwithstanding many provisions contained in the Indian Constitution whereby the Centre has given powers to override the provinces [States], nonetheless, it is a Federal Constitution."

Ultimately, the Indian Constitution is neither purely federal nor purely unitary; it functions as a unique structural synthesis. It prioritizes national integrity and the collective interest during times of crisis, while preserving regional autonomy during times of peace. Thus, it is best described as a "Quasi-federal system with a strong centralizing core" designed to facilitate unified national growth.
