Theoretical Background of Division of Power in Federal Systems

Every functioning democracy faces a basic problem: how do you give a government enough power to govern, while stopping it from becoming so powerful that it crushes the very people it is meant to serve? The answer that most modern constitutions, including ours, settled on is the division of power. Instead of concentrating authority in one person or one body, power is split, distributed, and made to check itself. But this idea did not appear overnight. It grew over centuries through the writings of jurists and philosophers who watched monarchies turn tyrannical and asked whether structure itself could protect liberty. Understanding this theoretical background is essential, because the federal and constitutional arrangements we live under today are direct descendants of these debates.

What division of power actually means 🔗

Before tracing the history, it helps to be clear about the term, because “division of power” is used in two related but distinct senses.

The first is the separation of powers, which divides government functions among different organs. Legislative power makes laws, executive power enforces them, and judicial power interprets and applies them. The second is the federal division of powers, which divides authority territorially between a central government and regional units such as states or provinces. Most modern constitutions combine both. A federation typically separates functions horizontally among branches and distributes them vertically between levels of government, creating what one famous essay called a “double security” for the rights of the people.

The early problem of sovereignty 🔗

The story begins, somewhat counterintuitively, with a thinker who argued against dividing power. The 16th-century French jurist Jean Bodin is widely regarded as the source of the modern concept of sovereignty. Writing during France’s brutal wars of religion, Bodin’s Six livres de la République (1576) defined sovereignty as a supreme, perpetual, and indivisible power, marked by the ability to make law without anyone else’s consent.

Why Bodin still matters here 🔗

For Bodin, the high powers of government could not be shared among separate agents but had to be concentrated entirely in a single individual or group. On the surface, this seems like the opposite of division of power. But Bodin made a subtle distinction between sovereignty (the ultimate law-making authority) and government (the day-to-day administration of the state). Scholars note that this very distinction anticipated later liberal doctrines of separating powers and subordinating the executive to the legislature. In trying to explain where supreme authority lay, Bodin opened the door for others to ask how its exercise could be divided up. His insistence that sovereignty was indivisible would later be challenged precisely by the rise of constitutional separation of powers and federal states.

Montesquieu and the architecture of liberty 🔗

The decisive contribution came nearly two centuries later from another French thinker, Charles-Louis de Secondat, Baron de Montesquieu. His 1748 treatise The Spirit of the Laws pleaded in favour of a constitutional system of government and the separation of powers, and its ideas went on to shape modern democratic government across the world.

The three powers 🔗

Montesquieu identified three sorts of power in every government: the legislative, the executive, and the judicial. The legislative power makes laws, the executive enforces them, and the judicial power interprets them when deciding cases between people. His central claim was blunt: liberty cannot survive if these powers are combined. As he argued, combining the judicial power with the legislative and executive is the road to tyranny. If the judge were also the lawmaker, the life and liberty of citizens would be exposed to arbitrary control; if the judge were also the enforcer, the judge might act with violence and oppression.

The principle behind this is captured in his famous formulation that power should be a check to power. Where all three functions sit in the same hands, whether those of one ruler or a single assembly, nothing prevents the abuse of authority. Dividing the functions among different bodies allows each to restrain the others.

From theory to influence 🔗

Montesquieu’s work was translated into English in 1750 and was received well in both Great Britain and the American colonies, where it influenced the framers of the United States Constitution. The English jurist William Blackstone absorbed these ideas into his enormously influential commentaries on English law, and through Blackstone and direct readings of Montesquieu, the principle travelled across the Atlantic.

The American framers and “double security” 🔗

The framers of the American Constitution, including James Madison, Alexander Hamilton, and Thomas Jefferson, treated the separation of powers as essential to safeguarding liberty. Madison’s The Spirit of the Laws was, by his own circle’s account, widely read by the founders, and Montesquieu’s tripartite framework became the backbone of the new constitutional design.

Ambition counteracting ambition 🔗

But the Americans added something important. The mere paper separation of functions, they realised, was not enough. In Federalist No. 51, Madison argued that the real safeguard against the gradual concentration of power lay in giving each branch the constitutional means and personal motives to resist encroachments by the others. His memorable phrase, “ambition must be made to counteract ambition,” reflected a hard-headed view of human nature: rather than hoping officials would behave well, the constitution should pit their self-interest against each other so that no single branch could dominate.

This is the origin of checks and balances, the mechanism that lets each branch limit the others, through devices like the executive veto, legislative override, and judicial review. Madison further described the federal system as offering a double security: power is first divided between two levels of government, and then the portion given to each is further subdivided among separate branches. This combination of separation of powers and federalism is exactly the model that later constitutions, including ours, would study closely.

Different federations, different models 🔗

Once federalism took hold, different countries divided power in ways that reflected their own histories. The way a constitution lists and allocates subjects between the centre and the regions tells you a great deal about where it places its trust.

The United States and Australia: power to the states 🔗

The US Constitution of 1787 is often described as the cornerstone of the first modern federal state, and its success inspired many other countries to adopt federal forms of government. It enumerates the powers of the national government and leaves the residual, or leftover, powers with the states. Australia, whose federation came together from separate British colonies, followed a similar logic. Its constitution lists the areas where the national Commonwealth can legislate, while powers not explicitly granted are generally reserved for the states. In both, the default tilts towards the regional units.

Canada: power to the centre 🔗

Canada took the opposite approach. Shaped by anxieties about national unity, the Constitution Act of 1867 listed powers for both levels but left the residual powers with the central government rather than the provinces. This made Canadian federalism more centralised in design, even though its actual practice has evolved considerably over time.

India: a deliberate blend 🔗

Our own Constitution studied all these models and chose a distinctive middle path. The division of legislative powers is set out primarily in Article 246, read with the Seventh Schedule, which sorts subjects into three lists: the Union List, the State List, and the Concurrent List. Parliament alone legislates on the Union List (defence, foreign affairs, banking and the like), state legislatures handle the State List (police, public health, agriculture), and both can legislate on the Concurrent List. Crucially, where a Concurrent List law conflicts, the Union law prevails. Following the Canadian rather than the American example, Article 248 vests the residual powers in the Union Parliament. This tilt towards the centre is one reason scholars often describe the system as quasi-federal rather than purely federal.

Separation of powers in the Indian context 🔗

It is worth noting that India does not follow a rigid separation of powers in the American style. The executive is drawn from and accountable to the legislature, so the two are deliberately fused rather than walled off. What our system maintains instead is a functional separation, reinforced by an independent judiciary with the power of judicial review. The broader theoretical lineage, however, is the same: the conviction, traceable to Montesquieu, that concentrating all authority in one place threatens liberty, and that structure is the surest defence against tyranny.

Why this background still matters 🔗

The theoretical journey from Bodin to Montesquieu to Madison was not an abstract academic exercise. It produced the practical vocabulary, separation of powers, checks and balances, residual powers, concurrent jurisdiction, that constitution-makers everywhere now use as standard tools. When a court strikes down a law, when the centre and a state argue over who can legislate on a subject, or when one branch resists overreach by another, the principles being applied were forged in these centuries-old debates. The division of power remains the single most important structural answer to the oldest question in political science: who guards the guardians?

What do you think? Does India’s tilt towards the centre, with residual powers held by the Union, strengthen national unity, or does it weaken the autonomy that genuine federalism is meant to protect? And in an age of strong executives, is Montesquieu’s warning about concentrated power more relevant now than it was in 1748?
