Structure of the U.S. Constitution

  • The Constitution has seven articles establishing the structure of the federal government.
  • Article 1 creates the legislative branch (Congress).
  • Article 2 establishes the executive branch (President, Vice President, agencies).
  • Article 3 creates the judicial branch (Supreme Court and lower courts).
  • Article 4 covers states' rights and admission of new states.
  • Article 5 outlines the amendment process.
  • Article 6 contains the Supremacy Clause, making federal law supreme.
  • Article 7 details the process for ratification.

The Bill of Rights and Amendments

  • The first ten amendments are called the Bill of Rights.
  • Amendments 1–10 guarantee rights like free speech, right to bear arms, due process, and more.
  • Some rights have been incorporated to apply to states (selective incorporation).
  • Third Amendment, grand jury clause of the Fifth, and Seventh Amendment civil jury right are mostly not incorporated.

Federalism and Separation of Powers

  • The Constitution established a stronger federal government than the Articles of Confederation.
  • Federalism refers to power division between federal and state governments.
  • States have general police powers; Congress has only enumerated powers.
  • Separation of powers divides government functions among legislative, executive, and judicial branches.

Checks and Balances

  • Each branch can limit the actions of the others (checks).
  • Passing a law requires action by both Congress and the President (balance).
  • President can veto laws; Congress can override vetoes and impeach; courts can declare actions unconstitutional.

Legislative Branch Details

  • Congress is bicameral: House of Representatives (435 members, 2-year terms, based on population) and Senate (100 members, 6-year staggered terms, 2 per state).
  • No term limits for congressional members.
  • Legislation process: committee review, chamber votes, presidential action, potential for veto override or pocket veto.

Executive Branch Details

  • President serves a 4-year term (max two terms), is commander-in-chief, and supervises executive agencies.
  • Vice President serves a 4-year term with no term limits and breaks Senate ties.
  • The President's Cabinet includes heads of 15 main executive departments.

Judicial Branch Details

  • Judiciary interprets and applies laws and can rule on constitutionality (judicial review).
  • Structure: U.S. Supreme Court (9 justices), 13 Courts of Appeals (circuits), 94 District Courts.
  • Supreme Court justices and federal judges have lifetime appointments.
  • Supreme Court jurisdiction includes original cases and appeals from federal/state courts based on federal questions.

Supreme Court Review and Process

  • Supreme Court mainly hears cases through discretionary certiorari, granted if four justices agree.
  • Only about 1% of petitions are granted each term.
