The process of amending the US Constitution is outlined in Article V, which sets forth two methods for proposing and ratifying amendments. The first method requires a two-thirds majority vote in both the House of Representatives and the Senate, while the second method involves a constitutional convention called for by two-thirds of the state legislatures. Once an amendment is proposed, it must be ratified by three-fourths of the states (38 out of 50) to become part of the Constitution. The process is designed to be difficult and time-consuming, ensuring that only significant changes affecting all Americans or securing citizens' rights are made.

Amendments can be proposed by Congress with a two-thirds majority vote in both the House and Senate
The process of amending the Constitution is outlined in Article V, which establishes two methods for proposing amendments. The first method, which has been the only method used thus far, involves Congress proposing an amendment with a two-thirds majority vote in both the House of Representatives and the Senate. This is done in the form of a joint resolution, which does not require the signature or approval of the President.
To achieve a two-thirds majority vote, the proposal must be supported by two-thirds of the members present in each house, assuming a quorum is met. This means that the vote requires the support of two-thirds of the members currently serving in each chamber, rather than two-thirds of all members, including those who may be absent. This ensures that a proposal can only succeed with broad support within Congress.
Once an amendment is proposed by Congress, it must then be ratified to become part of the Constitution. Ratification can occur through one of two methods determined by Congress. The first method requires the approval of three-fourths of the state legislatures, while the alternative method involves Congress calling for ratifying conventions in three-fourths of the states.
The process of amending the Constitution is deliberately difficult and time-consuming. The high threshold for approval in both the proposal and ratification stages ensures that amendments have broad support and are not made lightly. As a result, the Constitution has only been formally amended 27 times since it was drafted in 1787, with the first 10 amendments, known as the Bill of Rights, being adopted four years later.
While the process of proposing amendments through Congress has been the exclusive method utilised thus far, it is important to note that the Constitution also provides for the possibility of a constitutional convention. This alternative method can be initiated if two-thirds of the state legislatures request it. However, despite support from some backers, a constitutional convention has never been held to propose amendments.

Two-thirds of state legislatures can request Congress to call a Constitutional Convention
The process of amending the US Constitution is outlined in Article V, which establishes two methods for proposing amendments. One of these methods involves the state legislatures playing a direct role in initiating the amendment process. This method has never been used, but it remains a valid option.
Two-thirds of state legislatures can indeed request that Congress call a Constitutional Convention to propose amendments. This process bypasses the usual role of Congress in initiating amendments and allows the states to take a more active role in shaping the Constitution. This method has its supporters, including retired federal judge Malcolm R. Wilkey, who argued that it could address issues like gridlock and the excessive influence of interest groups.
For this process to be initiated, two-thirds of the state legislatures must formally apply to Congress, expressing their belief that a Constitutional Convention is necessary. Once this threshold is met, Congress is obligated to respond by calling for a Convention, where amendments will be proposed and debated.
The amendments proposed at the Convention must then be ratified to become part of the Constitution. Article V sets out two methods for ratification: the first method requires the approval of three-fourths of the state legislatures, while the second method involves approval by three-fourths of state ratifying conventions, with Congress determining the mode of ratification.
The process of amending the Constitution is deliberately difficult and time-consuming. It is designed to ensure that any changes made are carefully considered and broadly supported by the states and the American people. While the method of using a Constitutional Convention has yet to be utilised, it remains a valid option that could potentially provide an alternative avenue for proposing and enacting amendments.

A proposed amendment must be ratified by three-fourths of the states
The process of amending the Constitution is a complex and lengthy one. Since the Constitution was drafted in 1787, it has only been amended 27 times, indicating the difficulty of the amendment process. A proposed amendment must meet certain requirements to be ratified by three-fourths of the states, or 38 out of 50 states, and become part of the Constitution.
The first step in the process is for the proposed amendment to be passed by two-thirds of both houses of Congress or by a constitutional convention called for by two-thirds of the state legislatures. This step ensures that the amendment has significant support at the federal or state level. Once an amendment is proposed, it is then sent to the states for ratification.
The process of ratification can be initiated by either of two methods. The first method, as dictated by Article V of the Constitution, requires three-fourths of the state legislatures to ratify the amendment. The second method allows Congress to require three-fourths of state ratifying conventions to approve the proposed amendment. The choice of ratification method lies with Congress, which determines the mode of ratification for the states to follow.
The Office of the Federal Register (OFR) plays a crucial role in the amendment process. It examines ratification documents for legal sufficiency and authenticating signatures. Once the OFR verifies that it has received the required number of authenticated ratification documents, it drafts a formal proclamation for the Archivist to certify that the amendment is valid and has become part of the Constitution. This certification is published in the Federal Register and serves as official notice to Congress and the nation that the amendment process has been successfully completed.
The process of amending the Constitution is deliberately designed to be challenging, ensuring that any changes made are carefully considered and widely supported. The requirement for ratification by three-fourths of the states underscores the importance of state-level approval in the amendment process, reflecting the federal structure of the United States.

The OFR examines ratification documents for facial legal sufficiency and authentic signatures
The process of amending the Constitution is outlined in Article V, which establishes two methods for proposing and ratifying amendments. The first method involves both the House and the Senate proposing a constitutional amendment with a two-thirds majority vote. The second method, which has never been used, involves two-thirds of the state legislatures calling on Congress to convene a Constitutional Convention to propose amendments.
Once an amendment is proposed, it must be ratified. Ratification can be achieved through the legislatures of three-fourths of the states (38 out of 50 states) or by conventions in three-fourths of the states, as determined by Congress. This is where the Office of the Federal Register (OFR) comes into play.
The OFR plays a crucial role in the amendment process by examining the ratification documents for facial legal sufficiency and authentic signatures. Facial legal sufficiency refers to the determination that the content of the ratification documents meets the legal requirements without considering external factors. The OFR ensures that the documents are in proper order and have been duly authenticated. This includes verifying that the required number of states has provided valid ratification documents.
The OFR retains custody of these documents until an amendment is adopted or fails. Once the OFR confirms that the amendment has received the necessary ratification, it drafts a formal proclamation for the Archivist to certify. This certification confirms the validity of the amendment and its inclusion in the Constitution. The certification ceremony has, in recent times, been attended by dignitaries, including the President on some occasions.
The process of amending the Constitution is deliberately challenging and time-consuming. It requires broad support and consensus across the country. The OFR's role in examining ratification documents is an essential step in ensuring the integrity and authenticity of the amendment process.

The Archivist certifies the validity of ratification documents
The process of amending the Constitution is outlined in Article V, which establishes two methods for proposing and ratifying amendments. The first method, which has been utilised for all amendments so far, involves both the House and the Senate proposing a constitutional amendment with a two-thirds majority vote. The second method, which has never been used, involves two-thirds of state legislatures requesting Congress to convene a Constitutional Convention to propose amendments.
Once an amendment is proposed, it must be ratified. Ratification can occur through one of two methods determined by Congress. The first method requires ratification by three-fourths of the state legislatures, while the second method entails approval by three-fourths of state ratifying conventions.
After an amendment is ratified by the required number of states, the Office of the Federal Register (OFR) examines the ratification documents to ensure they meet the requirements for facial legal sufficiency and have authenticating signatures. If the documents are in order, the Director acknowledges receipt and maintains custody until the amendment is adopted or fails.
At this stage, the OFR verifies that it has received the required number of authenticated ratification documents. Subsequently, a formal proclamation is drafted for the Archivist to certify the validity of the amendment and its incorporation into the Constitution. This certification is not a substantive determination regarding state ratification actions but a confirmation of the facial legal sufficiency of the ratification documents. The Archivist's signature on the certification holds final and conclusive authority.
The signing of the certification has evolved into a ceremonial function graced by dignitaries, who may include the President. Notably, the Archivist performed the duties of the certifying official for the first time in 1992 for the ratification of the 27th Amendment, with the Director of the Federal Register signing as a witness.
