Quick Reference

Separation of Powers

The constitutional principle of dividing government authority among three independent branches -- legislative, executive, and judicial -- so that no single branch can dominate the others.

Checks and Balances

The system of overlapping powers that allows each branch of government to limit, oversee, or counteract the actions of the other branches, preventing any single branch from becoming too powerful.

Judicial Review

The power of courts to examine laws and government actions and declare them unconstitutional if they violate the Constitution. This power was established by the Supreme Court in Marbury v. Madison (1803).

Federalism

The division of governing power between a national (federal) government and state or regional governments, each with their own areas of authority. This vertical division of power complements the horizontal separation among the three branches.

Enumerated and Implied Powers

Enumerated powers are those specifically listed in the Constitution for each branch. Implied powers are those not explicitly stated but reasonably inferred from enumerated powers through the Necessary and Proper Clause.

Legislative Branch

The branch of government responsible for making laws, consisting of Congress (the Senate and House of Representatives). Article I of the Constitution grants all legislative powers to Congress, including the power to tax, declare war, regulate commerce, and control the federal budget.

Executive Branch

The branch of government responsible for enforcing and administering laws, headed by the President. Article II grants executive power to the President, who also serves as Commander in Chief of the military, negotiates treaties, and appoints federal judges and cabinet officials.

Veto Power

The constitutional authority of the President to reject legislation passed by Congress. A vetoed bill does not become law unless Congress overrides the veto with a two-thirds vote in both the House and Senate. The veto is one of the most powerful checks the executive branch holds over the legislative branch.
