5 min read•july 30, 2024
The U.S. Constitution's amendment process allows for formal changes to the nation's fundamental law. outlines two methods for proposing amendments and requires by three-fourths of the states. This process ensures stability while allowing for necessary updates.
Beyond formal amendments, the Constitution evolves through informal methods like judicial interpretation and legislative action. Key amendments, such as the Reconstruction and Progressive Era amendments, have expanded individual rights and reshaped government powers, reflecting changing societal values and needs.
Constitutional Amendment Process
Proposing Amendments
Article V of the U.S. Constitution outlines two methods for proposing amendments:
by Congress: Requires a two-thirds vote in both the House of Representatives and the Senate
Proposal by a national convention: Called by Congress at the request of two-thirds of the state legislatures (has never been used)
The president has no formal role in the amendment process and cannot veto a proposed amendment
Ratifying Amendments
After an amendment is proposed, it must be ratified by three-fourths of the states (currently 38 out of 50 states) to become part of the Constitution
States can ratify amendments through two methods, with Congress determining the mode of ratification:
State legislatures: The most common method, used for all but one amendment (21st Amendment)
: Used only for the 21st Amendment, which repealed
There is no specific time limit for the ratification of amendments, but Congress may set a deadline, typically seven years
Example: The Equal Rights Amendment (ERA), proposed in 1972, failed to achieve ratification within the original seven-year deadline and a subsequent three-year extension

Formal Amendment Process
The process, as outlined in Article V, involves proposing and ratifying specific changes to the Constitution's text
This process is intentionally difficult to ensure stability and prevent frequent or hasty changes to the Constitution
Examples of formal amendments include the abolishing slavery and the granting women's suffrage
Informal Methods of Constitutional Change
Informal methods of constitutional change include judicial interpretation, congressional legislation, executive actions, and evolving societal norms and practices
Judicial interpretation, particularly by the Supreme Court, can significantly shape the understanding and application of constitutional provisions without altering the text itself
Examples include the "right to privacy" recognized in and the application of the to the states through the 's Due Process Clause
Congressional legislation can expand or limit the scope of constitutional rights and powers
Examples include the Civil Rights Act of 1964, which expanded protections against discrimination, and the USA PATRIOT Act, which expanded government surveillance powers
Executive actions, such as executive orders and agreements, can also impact constitutional interpretation and implementation
Example: President Truman's Executive Order 9981, which desegregated the U.S. military
Evolving societal norms and practices can lead to changes in how constitutional provisions are understood and applied over time
Example: The growing acceptance of same-sex marriage leading to the Supreme Court's recognition of the right to marry for same-sex couples in (2015)
