Constitutions and separation of powers

The U.S. Constitution assigns national government powers to Congress, the president and the courts. Congress's main role is making laws. The executive branch carries laws out. Courts interpret laws and decide cases.

These roles are distinct, but their powers overlap. Checks and balances give one branch ways to limit another. A president can veto a bill passed by Congress. Congress can override that veto with the required votes. Courts can rule that a law conflicts with the Constitution when deciding a case.

Removal from office also involves checks. The House of Representatives can impeach a president, which means bringing formal charges. The Senate holds a trial and can remove the president if the required vote is reached. Impeachment alone does not remove someone.

These arrangements are intended to limit abuses. Their effectiveness depends on officials and institutions following constitutional rules.

This reading summarizes James Madison's argument in Federalist No. 51. It is not an excerpt from the essay.

Published in 1788, the essay explains why branches need ways to resist attempts by other branches to gain too much power. Madison argued that government cannot depend only on leaders having good intentions. Officials need legal tools and reasons to defend their branch's powers.

Government must have enough authority to govern, while also facing limits on that authority. Madison described dependence on the people as a primary control. Checks between institutions provided additional controls.

He also discussed the danger of a majority harming a minority. Dividing power was part of his proposed protection against abuse. This describes his reasoning for the Constitution's design; it does not prove that the design always prevents injustice.

Ask who is doing the work, then ask what area their authority covers. A state legislature and a national legislature both make laws, but they work at different levels. A national legislature and national courts work at the same level, but perform different kinds of work.

Federalism concerns levels. In a federal system, the constitution gives authority to both the national government and regional governments, such as states. Some responsibilities overlap. Courts may settle disputes about their boundaries. The United States is one example.

Unitary systems place ultimate authority at the national level. Regional and local institutions can still make many decisions. Having local decision-makers does not by itself make a country federal.

In a confederation, member governments retain most authority and give a central body limited responsibilities.

These categories describe where authority rests. They do not tell you whether a particular government treats people fairly or whether its leaders respect the rules.

Imagine two constitutional rules. One forbids government censorship. The other requires government to provide education. The first limits interference; the second creates a duty to act. A constitution can contain both kinds of rule.

To understand either rule, compare its words with people's experience. A promise of freedom can exist while officials violate it. Constitutionalism means that government actually operates within constitutional limits, rather than only possessing a document with that name.

The rule of law requires public officials to be accountable under law. Their offices do not place them above it. Due process requires fair legal procedures before government deprives someone of protected interests such as liberty.

For example, a leader's wish to punish someone does not replace the legal procedures that apply. Asking what rule authorizes an action, and what procedures it requires, helps distinguish a lawful use of power from a leader's personal demand.

Three terms describe different parts of the U.S. constitutional system.

Separation of powers concerns branches. Article I establishes Congress, Article II establishes the presidency, and Article III establishes the federal judiciary. Their main jobs are making laws, carrying them out and deciding cases.

Checks and balances concern limits between branches. The president can veto congressional bills. Congress can override a veto with the required votes. The president nominates Supreme Court justices, and the Senate can confirm or reject those nominations. Courts can find laws unconstitutional when deciding cases.

Federalism concerns levels. The Constitution divides authority between the national government and the states. Powers not given to the national government, and not forbidden to the states, are reserved to the states or the people.

These arrangements are intended to limit power. They do not guarantee that every official will respect the limits.
