Amendments to the United States Constitution

Amendments to the United States Constitution are formal changes or additions to the nation's foundational legal document. Since the Constitution's adoption in 1787, the amendment process outlined in its text has been used to adapt the framework of government and enshrine fundamental rights. To date, only 27 amendments have been ratified out of thousands proposed, making the process deliberately difficult. These changes have addressed critical issues from individual liberties and governmental structure to the expansion of the electorate and presidential succession.

Overview and ratification process

The process for altering the Constitution of the United States is detailed in Article V, which was a product of compromise during the Philadelphia Convention. An amendment can be proposed either by a two-thirds vote in both the Senate and the House of Representatives or by a national convention called by Congress at the request of two-thirds of the state legislatures; the convention method has never been used. For ratification, an amendment must then be approved by three-fourths of the states, either through their legislatures or through state ratifying conventions, a method used only for the Twenty-first Amendment. This dual-path system ensures broad national consensus is required for any change, a principle championed by framers like James Madison and Alexander Hamilton.

List of amendments

The first ten amendments, known collectively as the Bill of Rights, were ratified in 1791 and guarantee essential personal freedoms and procedural justice, such as those protected by the First Amendment and the Fourth Amendment. Subsequent landmark amendments have profoundly reshaped American society. The Thirteenth, Fourteenth, and Fifteenth Amendments, ratified after the American Civil War, abolished slavery and established principles of citizenship and voting rights. The Nineteenth Amendment extended suffrage to women, while the Twenty-sixth Amendment lowered the voting age. Others, like the Twenty-second and Twenty-fifth Amendments, have clarified presidential term limits and succession.

Unratified amendments

Six amendments that passed Congress have failed to achieve ratification by the requisite number of states. Two of these, the Congressional Apportionment Amendment and the Titles of Nobility Amendment, have no expiration date. Four others, proposed with explicit ratification deadlines, ultimately lapsed. These include the controversial Equal Rights Amendment, which fell short of ratification despite an extension granted by Congress, and the District of Columbia Voting Rights Amendment. The Child Labor Amendment also remains technically pending before state legislatures due to an unresolved question about its deadline.

Proposed amendments

Thousands of amendments have been introduced in Congress throughout history, though few reach the proposal stage. Notable recent proposals that have garnered significant debate but not the necessary two-thirds congressional vote include measures to mandate a balanced federal budget, to overturn decisions like Citizens United v. FEC regarding campaign finance, and to establish term limits for members of Congress. Other perennial proposals seek to alter the Electoral College system or to codify specific rights not currently enumerated in the Constitution.

Judicial interpretation

The application and scope of amendments are largely defined through judicial review by the Supreme Court of the United States. Landmark decisions have interpreted amendments to expand rights and define governmental power. For instance, Brown v. Board of Education applied the Fourteenth Amendment to end racial segregation, while Miranda v. Arizona established procedural safeguards under the Fifth Amendment. The court's interpretation, as seen in cases like District of Columbia v. Heller on the Second Amendment and Obergefell v. Hodges on the Fourteenth Amendment, continues to evolve, making the Supreme Court of the United States a central actor in the living history of the constitutional amendments.
