Yes. Ratified amendments are part of the Constitution, with the same legal force as the original text drafted in 1787. Article V says so directly: once an amendment clears the ratification process, it is “valid to all Intents and Purposes, as Part of this Constitution.”1Congress.gov. U.S. Constitution – Article V Overview That language erases any legal distinction between the original seven articles and the 27 amendments that followed. Every ratified amendment sits at the top of the American legal hierarchy, binding every branch and level of government.
The Framers wrote that phrase deliberately. They could have built a separate body of “supplementary law” with lesser authority. They didn’t. A judge interpreting the First Amendment’s free speech protections applies the same level of authority as when interpreting Congress’s powers under Article I. There is no hierarchy within the document itself, only between the document and everything beneath it.
How an Amendment Becomes Part of the Constitution
An amendment joins the Constitution only after it survives a two-step process. Congress proposes it by a two-thirds vote of both chambers, and three-fourths of the states (currently 38 of 50) then ratify it.1Congress.gov. U.S. Constitution – Article V Overview The President plays no role and cannot veto a proposed amendment.
Once the 38th state ratifies, the Archivist of the United States verifies the authenticated ratification documents and issues a formal certificate declaring the amendment valid and part of the Constitution.2Office of the Law Revision Counsel. 1 USC 106b The amendment and its certificate are then published in the Federal Register. At that point, the change is permanent law.
The filter is severe. More than 11,000 amendments have been proposed throughout American history, and only 27 have made it through.3National Archives. The Constitution – Amendments 11-27 That difficulty is the reason the amendments already in the Constitution carry the weight they do.
How Amendments Change the Original Text
Amendments reshape the Constitution in several ways.
Some fill gaps the original text left open. The Bill of Rights, ratified on December 15, 1791, guaranteed individual liberties like free speech, religious exercise, and protection against unreasonable searches that the Framers had not spelled out in the main document.4National Archives. Bill of Rights (1791)
Others expand who counts as a full participant in American democracy. The 19th Amendment, ratified in 1920, secured women’s right to vote. The 26th Amendment, ratified in 1971, lowered the voting age to 18.5USAGov. Voting Rights Laws and Constitutional Amendments These additions didn’t just sit alongside the election rules in Articles I and II. They changed who the government must include when it holds elections.
Amendments can also cancel each other. The 18th Amendment imposed a nationwide ban on manufacturing and selling alcohol. Fourteen years later, the 21st Amendment repealed it outright, stating plainly: “The eighteenth article of amendment to the Constitution of the United States is hereby repealed.”6Congress.gov. Twenty-First Amendment, Section 1 The original words of the 18th Amendment still appear in historical printings, but they carry zero legal force. The most recent ratification controls when there is a direct conflict.
Judges and lawmakers read the entire Constitution as a unified whole. Older provisions are interpreted through the lens of later amendments, which keeps the document coherent despite being written across different centuries.
Supreme Law Status
The Supremacy Clause in Article VI declares the Constitution “the supreme Law of the Land” and requires every state judge to follow it, regardless of any conflicting state law.7Congress.gov. U.S. Constitution – Article VI Because ratified amendments are part of the Constitution, they automatically share that supreme status. No state law, local ordinance, or federal statute can override an amendment. Any legislation that conflicts with one gets struck down by the courts.
This produces an unusual legal reality: an amendment itself cannot be ruled unconstitutional. Courts interpret amendments, decide how they apply to specific disputes, and determine their scope, but no court has the power to invalidate the text of an amendment. The Constitution is the standard against which all other law is measured. Regular federal statutes, by contrast, face constitutional review all the time and can be overturned if they conflict with the document.
Enforcement has teeth. When state or local officials violate rights protected by an amendment, the injured person can bring a federal lawsuit under 42 U.S.C. ยง 1983, which creates a cause of action against anyone who deprives a person of constitutional rights while acting under government authority.8Office of the Law Revision Counsel. 42 U.S. Code 1983 – Civil Action for Deprivation of Rights The 14th Amendment’s guarantee of equal protection has generated enormous volumes of litigation forcing states to change discriminatory laws and practices.9Constitution Annotated. Fourteenth Amendment Equal Protection and Other Rights
When a Proposed Amendment Is Not Part of the Constitution
A proposal is not part of the Constitution until certification. This is where the Equal Rights Amendment comes in. Congress passed the ERA in 1972 with a seven-year ratification deadline, later extended to 1982. By the time the deadline expired, only 35 states had ratified it. Three additional states ratified after the deadline (Nevada in 2017, Illinois in 2018, Virginia in 2020), bringing the total to 38, but the Archivist of the United States has declined to certify the amendment. The Department of Justice’s Office of Legal Counsel concluded in 2020 and again in 2022 that the expired deadline is legally binding, and the National Archives has stated it cannot publish the ERA as part of the Constitution under current legal and procedural rulings.10National Archives. Statement on the Equal Rights Amendment Ratification Process
The ERA’s status remains a live political and legal dispute, but the underlying rule is clear: until an amendment clears every procedural hurdle and receives official certification, it is not part of the Constitution regardless of how many states support it.
Why the Distinction Matters
Once you understand that amendments are the Constitution rather than attachments to it, the strength of constitutional rights makes more sense. Repealing or modifying a constitutional right requires the same supermajority process that created it: two-thirds of Congress and three-fourths of the states.1Congress.gov. U.S. Constitution – Article V Overview No president can undo an amendment by executive order. No Congress can override one with a simple majority. No court can strike one down. That insulation from ordinary politics is exactly what gives constitutional rights their durability. The freedoms in the First Amendment and the equality guarantees in the 14th are not protected by the goodwill of whoever holds power at the moment. They are protected by the structural difficulty of changing the supreme law itself.
