The Union List: Central Government Legislative Powers in India

When India became a republic, the framers of the Constitution faced a delicate question: how do you govern a vast and diverse country without letting it pull apart at the seams? Their answer was a carefully designed system of dividing legislative powers between the central government and the states. At the heart of this system sits the Union List, a catalogue of subjects on which only the Parliament can make laws. Understanding it is essential to understanding why power flows the way it does in our federal structure.

What the Union List actually is 🔗

The Union List is one of three lists contained in the Seventh Schedule of the Constitution. The other two are the State List and the Concurrent List. Together, these three lists divide all the subjects of governance and tell us who has the authority to legislate on what.

The Union List, formally called List I, is the longest of the three. It originally contained 97 subjects, and through later amendments now stands at around 100. These cover the areas of greatest national significance. The key principle is exclusivity: only the Parliament can make laws on the subjects listed here. State legislatures have no say in these matters under normal circumstances.

The constitutional basis in Article 246 🔗

The legal authority for this division comes from Article 246 of the Constitution. The article uses a phrase worth noting: it begins with “notwithstanding anything in clauses (2) and (3).” This is called a non-obstante clause, and it matters a great deal. It means that the Parliament’s power over Union List subjects overrides everything else. If there is ever a conflict, the Union List takes precedence.

To break it down simply, Article 246 grants exclusive power to the Parliament over Union List subjects, allows both Parliament and state legislatures to legislate on Concurrent List subjects, and gives state legislatures exclusive power over State List subjects. The Union List sits firmly at the top of this arrangement.

The major subjects on the Union List 🔗

The subjects included here are not random. They were chosen because they require a single, uniform policy across the entire country. Imagine if each state had its own army, its own currency, or its own foreign policy. The country would quickly become ungovernable. Let us look at the most important categories.

Defence and national security 🔗

The very first entry on the Union List relates to the defence of India, including the army, navy, air force, and any other armed forces of the Union. National security cannot be divided among states. A coordinated defence policy, controlled by a single authority, is the only way to protect the nation’s borders and sovereignty. Related entries also cover the deployment of armed forces in states to assist civil power.

Foreign affairs and international relations 🔗

All matters that bring India into relations with foreign countries fall under the Union. This includes diplomatic relations, treaties, and agreements with other nations. A country must speak with one voice on the world stage. If individual states could sign their own treaties or conduct their own diplomacy, India’s international standing would collapse into chaos.

Atomic energy and strategic resources 🔗

The production and use of atomic energy is reserved exclusively for the central government. This is a sensitive area touching on both energy security and national defence. Keeping it under central control ensures safety, accountability, and a coherent strategic approach.

Railways and national infrastructure 🔗

Railways are a classic example of why centralisation makes sense. The Indian Railways network connects the entire country, crossing state boundaries constantly. Managing it through a single central authority ensures that trains run smoothly across states without the friction of different rules in different regions.

Banking, currency, and finance 🔗

The Union List covers banking, including the Reserve Bank of India and the regulation of financial institutions, along with currency and coinage. A nation needs one stable currency and a unified banking system. If states issued their own money or set their own banking rules, the economy would fragment instantly.

Communication and connectivity 🔗

Posts, telegraphs, telephones, wireless, and broadcasting all sit on the Union List. These networks tie the country together, and uniform standards across the nation keep communication seamless. Other significant entries include citizenship, census, audit of government accounts, and inter-state trade and commerce.

Why these subjects were centralised 🔗

There is a clear logic running through the entire Union List. The framers placed subjects here when they believed a uniform policy was needed across the whole country. National defence, a single currency, one foreign policy, and integrated transport are matters where having fifty different approaches would be disastrous.

This choice reflects a deliberate decision about the kind of federation India should be. After Partition and the trauma of integrating hundreds of princely states, the Constitution’s makers wanted a strong centre capable of holding the country together. India deliberately followed the Canadian model, where residuary powers are vested in the Centre, rather than the American or Australian model where they rest with the states. This gives Indian federalism a distinct centralising tilt.

The Union List and federal supremacy 🔗

The Union List does more than simply list subjects. It establishes a hierarchy of power. Because of the non-obstante clause in Article 246, whenever there is overlap or conflict between the lists, the Union prevails.

Residuary powers and Article 248 🔗

What happens when a subject does not appear on any of the three lists? This is where Article 248 comes in. It gives the Parliament exclusive power to make laws on any matter not enumerated in the Concurrent List or the State List. These are called residuary powers.

This is hugely important in the modern era. Subjects like cyber law, information technology, and space exploration did not exist when the Constitution was written. They fall under residuary powers, which means the central government can legislate on them. This acts as a legislative safety net, ensuring there are no gaps in the law as society evolves.

How courts resolve disputes 🔗

Sometimes a law seems to touch on more than one list. To resolve such situations, courts use the Doctrine of Pith and Substance, which examines the true nature and dominant purpose of a law rather than its incidental effects. If the core of a law falls within Parliament’s competence, it remains valid even if it incidentally touches a state subject.

In the landmark case of Union of India v. H.S. Dhillon (1972), the Supreme Court confirmed Parliament’s exclusive authority over residuary subjects, reinforcing central legislative supremacy. Such judgments have consistently strengthened the Union’s dominant position within the federal structure.

What this means for Indian federalism 🔗

The Union List is often described as evidence that India has a quasi-federal structure with a strong unitary bias. The sheer number of subjects on this list, combined with the residuary powers resting at the centre, means the balance of legislative power leans firmly towards the Union.

This design has both strengths and tensions. On the positive side, it ensures coherence, stability, and the ability to handle national crises with a unified response. A single authority over defence, currency, and foreign affairs gives India the cohesion to function as one nation despite enormous diversity. On the other hand, critics argue this centralisation can sometimes undermine state autonomy and the spirit of cooperative federalism.

The introduction of the Goods and Services Tax through Article 246A is a recent reminder that this division is not frozen. It created a new model of shared taxation, showing that the relationship between the Union and the states continues to evolve. Yet the core principle remains: on matters of national importance, the Parliament speaks for the whole country.

What do you think? Given how many critical subjects the Union List places under central control, do you believe this centralising tilt strengthens India or weakens the autonomy that states need to govern effectively? And as new fields like artificial intelligence and digital governance emerge under residuary powers, should the Constitution be reconsidered to give states a greater voice?
