Why Political Power Must Have Limits

By Daniel Sardá · May 01, 2026

In this article

The limits on political power are moral, legal and institutional barriers that prevent those who govern from turning public authority into personal, partisan, bureaucratic or majoritarian domination.

Political power must have limits because it concentrates legal coercion: it can impose binding laws, collect taxes, regulate, sanction, expropriate, use courts, command the police and apply public force.

In simple terms: the problem is not only who governs, but how much power they can exercise and what barriers exist to protect the citizen when that power makes mistakes, becomes corrupt or chooses to abuse.

Key idea: rights must not depend on the virtue, popularity or promises of whoever governs.

From a classical liberal perspective, limiting power does not mean destroying all public authority. It means subjecting it to general rules, individual rights, a Constitution, separation of powers, the rule of law, institutional checks and accountability.

Why political power must have limits

Political power is necessary for some functions: protecting rights, enforcing contracts, prosecuting crimes, resolving conflicts and sustaining a common legal framework.

But that same power can become a threat if it has no limits.

The authority that punishes criminals can also persecute dissidents. The institution that collects taxes for public functions can also finance clientelism or privileges. The regulator that says it protects consumers can also close markets in favor of allies. The court that should defend rights can become an instrument of the executive.

Political power must have limits because no ruler owns society. No majority may dispose of people’s liberty, property, conscience, expression or private life as if they were raw materials for a collective project.

The classical liberal question is not whether all government is illegitimate. The question is what government may do, under what limits, under which controls and before which rights it may not cross.

What makes political power different

Not all social power is the same.

A business owner may influence workers or consumers, but he cannot legally imprison someone who rejects his product. A media outlet may influence public opinion, but it cannot collect taxes. A church, union, university or association may hold moral or social authority, but it cannot use courts and police on its own account.

Political power is different because it rests on legal coercion.

It can impose:

That capacity requires special justification.

Coercion can be necessary to protect rights against violence or fraud. But if it is not limited, it can become a tool of fear, punishment, dependence and political obedience.

The liberal reason for limiting power

Classical liberalism starts from a basic moral idea: the person does not belong to the state.

A person’s life, work, property, conscience, speech, associations and projects are not concessions from the ruler. Nor are they gifts from the majority. They are spheres of liberty that power must respect.

That is why classical liberalism insists on limiting political power. Not because of an anti-state reflex, but because history shows that power without barriers tends to expand, justify itself and protect itself.

A ruler may say he acts for the people. A majority may say it decides in the name of justice. A bureaucrat may say he regulates for order. A judge may say he interprets for the common good.

The question does not disappear: what limits do they face?

Individual rights are precisely barriers against that claim of unlimited power. Freedom of expression limits the censor. Property limits the confiscator. Due process limits the persecutor. Equality before the law limits the privileged. Separation of powers limits the ruler who wants to control everything.

Concentration of power and arbitrariness

Concentration of power appears when a person, party, majority, bureaucracy or institution accumulates too many powers without real counterweights.

It may concentrate laws, budget, courts, police, public media, regulators, permits, state-owned enterprises, armed forces, electoral authorities or public banks.

The risk is not theoretical. When one authority decides too much, law begins to resemble that authority’s will.

The citizen stops asking “what does the rule say?” and starts asking “what does the powerful actor want?”

That change destroys legal certainty. If the permit depends on the official, if the trial depends on the party, if the license depends on contacts, if the investigation depends on loyalties and if the contract depends on political convenience, freedom becomes uncertain.

Arbitrariness does not need to eliminate all laws. It can use vague laws, broad decrees, permanent emergencies and selective sanctions.

That is why concentration of power is dangerous even when it uses legal language.

Discretionary power vs general rules

Not every form of administrative discretion is illegitimate. In some cases, an authority must apply criteria to concrete situations: granting a license, prioritizing resources, inspecting risks or responding to emergencies.

The problem appears when discretion becomes arbitrariness.

Healthy discretionary power has public criteria, limits, review, reasons, procedures and the possibility of challenge. Arbitrary power decides according to convenience, loyalty, whim, pressure or political interest.

The difference matters in daily life.

A permit system can organize an activity if its requirements are clear, general and reviewable. But it becomes domination if the official can decide who works, who imports, who opens a shop, who receives foreign currency, who obtains a public contract or who avoids sanction.

Unchecked discretion feeds corruption.

If a person needs permission to live, work, trade or speak, the official who controls that permission gains power over his life. That is where bribes, favors, fear and clientelism are born.

Constitutional limits

Constitutional limits are higher restrictions on political power.

A Constitution should not be decorative. It must define competences, procedures, rights and barriers that government cannot cross without breaking the framework of legitimacy.

This includes three dimensions.

First, competences: what each organ of the state may do.

Second, procedures: how it must act, legislate, judge, spend, reform or sanction.

Third, rights: which spheres it may not violate even when it has power, votes or popularity.

The Declaration of the Rights of Man and of the Citizen of 1789 stated a decisive idea: a society without guarantees of rights and separation of powers lacks a Constitution in the strong sense.

The point remains valid. A Constitution that lists rights but cannot stop power functions as a promise without a guarantee.

Rule of law as a limit on power

The rule of law is one of the main mechanisms for limiting political power.

It means government is also subject to law. It does not govern through whims, secret orders, retroactive punishments or ad hoc decisions. It must act through public, general, relatively stable rules applied with due process.

But this article is not meant to repeat the full topic of the rule of law. What matters here is its function inside a broader logic: preventing power from becoming personal will.

The rule of law limits because it requires:

If the ruler can change rules after the fact, punish without trial, expropriate without defense or apply norms only against enemies, law stops limiting. It becomes a weapon.

Separation of powers and institutional checks

Separation of powers responds to a simple intuition: whoever concentrates too many functions ends up without effective control.

If the same authority makes the law, executes it, judges its violations, controls the budget, commands the police and decides which rights matter, the citizen is defenseless.

Montesquieu understood that political liberty requires preventing that concentration. Madison and the authors of The Federalist Papers developed the idea of checks and balances: power must check power.

Institutional checks can include:

These mechanisms are not decorative obstacles. They are safeguards against abuse.

Still, they should not be idealized. Checks can be captured, used factionally or turned into destructive obstruction. That is why they need rules, transparency, defined competences and institutional culture.

Constitutional democracy vs unlimited democracy

Democracy is an important way to limit power: it allows citizens to elect, replace and control rulers.

But democracy alone is not enough.

A majority can violate rights. An elected president can persecute opponents. A parliament with popular support can close media outlets, confiscate property, manipulate courts or change electoral rules to prevent alternation.

That is why the liberal tradition defends constitutional democracy, not unlimited democracy.

Constitutional democracy combines elections with limits: individual rights, separation of powers, a Constitution, independent judges, legality, freedom of the press, legitimate opposition and protection of minorities.

Unlimited democracy interprets the vote as authorization to do anything.

That error is dangerous. Voting legitimizes governments within rules; it does not make every violation of rights legitimate.

The tyranny of the majority appears when a majority uses political power to subject individuals or minorities. It does not stop being tyranny because it has electoral support.

Populism and the erosion of limits

Populism often attacks institutional limits by presenting them as obstacles against “the people.”

The populist leader claims to represent the popular will exclusively. From that position, he treats courts, the press, parliament, regional authorities, businesses, universities, civil associations or minorities as internal enemies.

The logic is simple: if the leader embodies the people, whoever limits the leader limits the people.

That idea destroys constitutional democracy.

Limits are no longer seen as citizen guarantees, but as elitist obstacles. Judicial independence is denounced as conspiracy. Critical press is presented as betrayal. The opposition becomes an enemy. The Constitution is reinterpreted as a provisional obstacle.

Permanent emergency also appears.

Economic crisis, external threat, sabotage, culture war, insecurity or social emergency can be used to concentrate power. Some emergencies are real. The problem is turning exception into an ordinary method of government.

State capture and legal privileges

Unlimited political power does not only produce repression. It also produces privileges.

State capture occurs when private groups, parties, bureaucrats, firms, unions, military actors, judges, contractors or influence networks use public power for their own benefit.

Sometimes this is illegal corruption. Other times it is legal privilege formally approved.

Examples include:

This connects with the free market under general rules. A free economy is not an economy of business owners protected by the state. That is crony capitalism.

Economic competition weakens when political power decides who enters, who competes, who receives subsidies and who remains protected.

Without limits, law stops being a common rule and becomes an instrument of rent-seeking.

Individual rights as barriers against power

Individual rights are not legal ornaments. They are barriers against power.

Freedom of expression prevents government from deciding which opinions may circulate. Freedom of association protects parties, unions, churches, businesses, media outlets, NGOs and communities. Religious liberty and freedom of conscience limit the power that wants to standardize beliefs.

Due process protects the accused against political punishment. The presumption of innocence prevents conviction by propaganda. The right to defense prevents the court from becoming merely an arm of government.

Negative liberty helps explain this point: a person needs a sphere protected against arbitrary interference.

Equality before the law is also essential. If allies and adversaries live under different rules, there are no real limits. There are political castes.

Individual rights exist so that citizens do not have to beg for permission every time they want to speak, work, associate, defend themselves or keep what is theirs.

Private property and limits on political power

Private property is a material barrier against political power.

A person with a home, tools, savings, business, land, contract or defensible patrimony has more independence from the official, the party or the subsidy. He can plan, refuse, start a business, support a family and participate in civil society.

If the state can dispose of property arbitrarily, freedom is weakened.

Expropriation can exist within strict constitutional frameworks, but it requires a legitimate cause, procedure, control and compensation when applicable. Arbitrary confiscation, by contrast, turns property into a revocable permission.

Taxes also need limits. Not every tax is confiscation, but a discretionary, retroactive, selective or impossible-to-comply-with tax burden can be used as political punishment or as a mechanism of subjection.

Legal certainty over property and contracts does not protect only large companies. It protects ordinary citizens: their home, motorcycle, tools, shop, inventory, plot, account and work.

Civil society, press and citizen vigilance

Limits on power are not only legal. They are also social.

A strong civil society creates spaces of autonomy from the state: families, associations, churches, media, universities, companies, guilds, unions, communities, foundations and voluntary organizations.

Tocqueville understood that free associations help resist centralization. When everything depends on the state, the citizen is isolated before a huge machine.

Free press also limits power. It investigates, reveals, irritates and allows citizens to know about abuses. Without public information, accountability becomes fiction.

Political alternation is another limit. If a group knows it can lose power, it has stronger incentives not to destroy all rules. If it controls courts, elections, media and budget so it never has to leave, democracy is emptied.

Federalism and decentralization can also help. They do not guarantee liberty by themselves, but they reduce the risk that every decision becomes concentrated in one political center.

Limiting power does not mean weakening institutions

A common mistake is to think that limiting power means weakening the state until it becomes incapable.

It does not.

A state can be strong in protecting rights and limited in violating them. It can have the capacity to prosecute crimes, enforce contracts, protect borders, administer justice and respond to emergencies without having unlimited power over social life.

The difference is decisive.

A weak state does not protect liberty if it cannot control violence, guarantee justice or enforce basic rules. But an unlimited state also does not protect liberty if it censors, confiscates, persecutes or distributes privileges.

The liberal objective is not to abolish all public authority. It is to build authority under rules.

That is why limited government should not be confused with anarchy or a failed state. The question is not only size. It is control of power.

Venezuela and Latin America: why this matters

In Venezuela and Latin America, limits on political power are not an abstract discussion.

The region has had constitutions, elections and declarations of rights. But it has also suffered caudillismo, hyper-presidentialism, prolonged states of exception, subordinated justice, clientelism, corruption, militarization, censorship, confiscations, discretionary bureaucracy and privileges for allies.

That experience teaches one lesson: written rights are not enough if power faces no real limits.

A government can speak of the people while concentrating power. It can invoke social justice while distributing privileges. It can promise order while destroying independent judges. It can defend sovereignty while turning the citizen into someone dependent on political permission.

The problem is not only who holds office. The problem is what that office allows him to do.

That is why limits on power especially protect the ordinary citizen. Those with contacts can seek exceptions. Those without them need general rules, due process, independent judges, defensible property and freedom to associate, speak and work.

Common mistakes about limits on political power

“Limiting power means weakening the state”

No. Limiting power means subjecting it to rules, rights and checks. A limited state can be strong in protecting rights and weak in abusing them.

“If the people voted, the government can do anything”

False. Voting legitimizes governments within constitutional limits. It does not authorize censorship, confiscation, persecution, selective impunity or destruction of rights.

“Institutional checks are elitist obstacles”

They can be abused, but their liberal function is to protect the citizen against concentrated power. Without checks, the ruler becomes judge in his own cause.

“A good leader does not need limits”

Every leader needs limits. Institutions are not designed by assuming permanent virtue, but by considering error, ambition, corruption and incentives.

“More laws always limit power”

No. Some laws limit government. Others give it more discretion. A vague law authorizing “what is necessary” can be a tool of unlimited power.

“Discretionary power is necessary to govern quickly”

Some flexibility can be useful, but without criteria, checks and review it becomes arbitrariness. Speed does not justify turning rights into removable obstacles.

“Limits only protect the powerful”

In a captured society, the powerful often negotiate exceptions. General limits mostly protect the citizen without contacts, who needs rules and impartial judges.

“Every state intervention violates liberal limits”

Not necessarily. An intervention may be legitimate if it respects competition, legality, generality, proportionality, due process, control and affected rights.

Frequently asked questions about limits on political power

What does it mean to put limits on political power?

It means establishing legal, moral and institutional barriers so rulers, majorities, officials and state organs cannot act arbitrarily or violate rights.

Why must political power have limits?

Because it concentrates legal coercion: binding laws, taxes, regulation, sanctions, courts, police and public force. Without limits, that coercion can become abuse.

What risks does concentration of power create?

It increases the risk of arbitrariness, censorship, corruption, persecution, selective impunity, legal privileges, state capture and weakening of rights.

What is the difference between limited power and discretionary power?

Limited power acts within general rules, competences and checks. Discretionary power decides with a broad margin; it may be necessary in specific cases, but without checks it degenerates into arbitrariness.

What are constitutional limits?

They are higher restrictions over competences, procedures and rights that government cannot legitimately violate.

What is the relationship between limits on power and the rule of law?

The rule of law is one of the main mechanisms for limiting power: it requires legality, general rules, due process, independent judges and equality before the law.

What role does separation of powers play?

It prevents one authority from concentrating legislation, execution and justice. It allows power to check power.

What are checks and balances?

They are institutional mechanisms that allow abuses to be controlled: judicial review, legislative oversight, vetoes, audits, procedures, decentralization and accountability.

Can a democracy have unlimited power?

It can try, but then it stops being constitutional democracy. The majority cannot legitimately eliminate individual rights or destroy checks in order to perpetuate itself.

What is the tyranny of the majority?

It is the use of majority power to violate the rights, property, expression, association or due process of individuals or minorities.

How does populism erode limits on power?

It presents the leader as the embodiment of the people and portrays courts, press, opposition, the Constitution or checks as illegitimate obstacles.

What is state capture?

It is the use of public power by groups, parties, firms, bureaucrats or influence networks to obtain privileges, rents, impunity or protection from competition.

Why do legal privileges violate a free society?

Because they turn law into a tool of favoritism. Instead of general rules, they create benefits for some and costs for others.

Does limiting power mean a minimal state?

Not necessarily. Limiting power means controlling it through rules and rights. The minimal state is a specific theory about reduced state functions.

Why does this matter for Venezuela and Latin America?

Because the region has suffered presidential concentration, subordinated justice, states of exception, clientelism, corruption and formal rights without effective protection.

Without limits, power turns rights into concessions

Limits on political power exist for a simple reason: no human being, majority, party, bureaucrat, judge, military actor or expert should have enough authority to turn the freedom of others into a revocable permission.

Power can protect rights. But it can also destroy them.

That is why a free society needs a Constitution, separation of powers, the rule of law, individual rights, private property, equality before the law, institutional checks, civil society and accountability.

The alternative is not unlimited power or chaos. That is a false dichotomy. The real alternative is controlled power or arbitrary power.

A government limited by rights can act legitimately. A government without limits turns law into will, property into concession, expression into risk and citizenship into obedience.

That is why limiting political power is not a doctrinal obsession. It is a basic condition for people to live as free citizens rather than as subjects of whoever commands.
