The United States Constitution, drafted in 1787 and in force since 1789, is the oldest and shortest written national constitution in existence. It is a rigid document consisting of a Preamble and seven original Articles, requiring an arduous amendment process involving a two-thirds majority in Congress and ratification by three-fourths of the states.
Salient Features of the US Constitution
- Popular Sovereignty: The system recognizes that supreme power belongs to the people, and the government derives its “just powers” from the consent of the governed.
- Separation of Powers: The functions of government are divided into three distinct and independent branches: the Legislative (Congress), the Executive (President), and the Judiciary (Supreme Court).
- Checks and Balances: To prevent the abuse of power, each branch possesses specific authorities to limit the others. For example, the President can veto Congressional bills, the Senate must ratify presidential appointments, and the Supreme Court can declare laws unconstitutional.
- Bill of Rights: The first ten amendments explicitly list rights and liberties—such as freedom of speech, religion, and the right to a fair trial—that the federal government is prohibited from infringing.
- Judicial Review: The judiciary serves as the guardian of the Constitution, possessing the power to strike down legislative acts or executive orders that are inconsistent with the supreme law of the land.
The Federal System of Government
The United States is considered a truly federal constitution, establishing an “indestructible union of indestructible states“.
- Division of Powers: Authority is shared between the national government and 50 state governments. The national government holds enumerated powers related to national importance (defense, foreign policy, and currency), while residuary powers are reserved for the states or the people under the Tenth Amendment.
- Dual Polity and Sovereignty: Each state possesses its own constitution, legislature, executive, and judiciary. This framework includes dual citizenship, where Americans are simultaneously citizens of the USA and their state of residence.
- Bicameralism and State Representation: The US Congress is divided into two houses to balance popular will with state sovereignty. The Senate is the world’s most powerful upper chamber, granting each state equal representation (two members) regardless of population to protect smaller units from being dominated.
- Independent Judiciary: A federal judiciary resolves disputes between the central and state governments, maintaining the equilibrium of the federal structure.
The Presidential form of Government
The US executive branch follows a presidential system, characterized by a strict functional separation from the legislature.
- Sole Executive: The President serves as both the Head of State and the Head of Government.
- Independence from Congress: The President is elected for a fixed four-year term via an indirect Electoral College system and is not responsible to the legislature. The President cannot dissolve Congress, nor can Congress remove the President except through the difficult process of impeachment for high crimes and misdemeanors.
- The Cabinet: Unlike parliamentary systems, the US Cabinet is a purely advisory body composed of heads of executive departments (Secretaries) who serve at the President’s pleasure. Cabinet members are prohibited from holding a seat in Congress concurrently.
- Veto Powers: The President possesses a suspensive veto over bills passed by Congress. While Congress can override this with a two-thirds majority in both houses, the President can also utilize a “pocket veto” by refusing to sign a bill if Congress adjourns within ten days of its submission.
- Commander-in-Chief: The President is the supreme commander of the armed forces and conducts foreign relations, though treaties require two-thirds approval from the Senate.
