Constitution Ratification vs Amendments: Article VII and Article V
Article VII sets the original Constitution’s establishment rule: conventions in nine states, between the states ratifying it. Article V governs later amendments and requires a proposal stage followed by ratification in three-fourths of the states. The numbers and the acting institutions are different.
Article VII answers the original establishment question
Article VII says ratification by the conventions of nine states is sufficient to establish the Constitution between the states so ratifying. Its unit is a state convention, not a signature by a convention delegate, a popular vote counted across the whole country or an approval by nine members of Congress. [1]
The September 17, 1787 attestation records the Constitution’s completion and signatures in the federal Convention. That is a different act from ratification in the states. A timeline should preserve these verbs rather than presenting the signing day as proof that every state had already ratified.
Article VII’s “between” qualification also matters. The clause does not say a ninth ratification proves that every remaining state consented. To date an actual state’s action or the new government’s operation, examine the separate ratification and implementation records.
Article V supplies two ways to propose an amendment
One route is Congress proposing amendments when two-thirds of both houses deem it necessary. The other starts with applications from the legislatures of two-thirds of the states, after which Congress calls a convention for proposing amendments. Neither stage, by itself, turns a proposal into a constitutional amendment. [1]
Count the institution named in the clause. “Two-thirds of the states” belongs to the state-legislature application route; it is not interchangeable with “two-thirds of both Houses.” This article does not infer a modern congressional vote denominator, quorum rule or procedural decision from the fraction alone.
The ratification stage has two modes and a different fraction
On a small screen, scroll the table sideways to read every column.
| Rule | Action and actor | Threshold | Result established |
|---|---|---|---|
| Article VII | State conventions ratify the original Constitution. | Nine states. | Establishment between ratifying states. |
| Article V, congressional proposal | Both houses of Congress propose amendments. | Two-thirds of both houses. | A proposal, still needing ratification. |
| Article V, convention proposal | State legislatures apply; Congress calls a proposing convention. | Applications from two-thirds of states. | An alternative proposal route. |
| Article V, legislative ratification | State legislatures ratify. | Three-fourths of states. | Amendment becomes part of the Constitution under the selected mode. |
| Article V, convention ratification | State conventions ratify. | Three-fourths of states. | The other ratification mode; Congress selects the mode. |
Congress chooses whether ratification is by legislatures or conventions. The text does not let a reader freely combine approvals from both modes into one total. It also preserves a restriction concerning equal suffrage in the Senate without a state’s consent and a historically dated limitation before 1808. Those qualifications should not disappear from a claim that Article V permits absolutely any change. [1]
Round state thresholds upward, and identify the assumed state count
Fractions of states require whole-state results. In an explicitly hypothetical thirteen-state amendment example, three-fourths is 13 × 3/4 = 9.75, so ten state approvals are needed. Article VII nevertheless says nine conventions for the original establishment. Ten is a calculation of an amendment fraction, not a correction to Article VII’s written nine.
With an assumed fifty states, two-thirds is 33⅓, requiring at least 34 state-legislature applications; three-fourths is 37.5, requiring at least 38 ratifying states. These are different stages. The arithmetic does not prove an actual convention was called or an actual amendment ratified.
The thirteen-state example is not presented as the state count on every later historical amendment date. A real historical calculation needs the states included at the time and the ratification mode selected. In particular, do not apply the hypothetical count automatically to the Bill of Rights.
Check three claims against the correct clause
All three cases are invented exercises using stated assumptions.
Case 1
Assume thirteen states. Nine conventions ratify the original Constitution. Is nine necessarily too few because three-fourths of thirteen is 9.75?
Show answer and explanation for case 1
No. Article VII expressly gives the original establishment threshold as nine.
The three-fourths requirement belongs to Article V amendments, not Article VII’s original ratification rule. Article VII also limits its establishment wording to the states ratifying. The two provisions have different tasks, so using one fraction to overwrite the other clause is a category error.
Case 2
Assume fifty states and 34 state legislatures submit the relevant applications. Has an amendment already been ratified?
Show answer and explanation for case 2
No. That count concerns the convention-proposal route.
Thirty-four meets the rounded two-thirds state-application threshold in this arithmetic example. Proposal and ratification remain separate. Article V subsequently requires ratification by the selected mode in three-fourths of the states; the example supplies no evidence that this later stage happened.
Case 3
Assume fifty states and legislative ratification has been selected. Thirty-seven state legislatures approve. Does rounding 37.5 down make that enough?
Show answer and explanation for case 3
No. At least 38 are required in the stated arithmetic example.
A whole-state count must meet or exceed the fraction. Thirty-seven divided by fifty is 74 percent, below three-fourths. Thirty-eight is 76 percent. These percentages check the calculation; they do not determine disputed legal questions about a particular ratification.
A precise date note needs the action, actor and rule
Write “signed in the Convention” for the September 17 attestation; write “ratified by this state convention” only with the relevant state record. For an amendment, identify proposal and ratification as separate stages, then name the selected mode. The Bill of Rights guide applies that distinction to the twelve proposed articles and ten amendments ratified in 1791.
This is an explanation of the displayed historical text and independently checked hypothetical arithmetic. It is not a reconstruction of every state’s ratification history or advice on contemporary amendment litigation. The older Articles of Confederation had a different alteration rule; do not carry its unanimity requirement into Article VII or V.
