Constitutions are mutable.
Article V of the U.S. Constitution provides a path for American citizens to call a convention for proposing amendments should the legislature fail to act or require reform. The convention method has never been used, and no one is agreed on how it should run. Mutable is writing the rulebook.
Mutable means changeable
The Framers left us a second way in. On purpose.
Article V gives two ways to change the Constitution. Congress can propose an amendment with a two-thirds vote of both houses. Or the states can: when 34 legislatures apply, Congress must call a convention, and that convention can propose amendments of its own. Either way, nothing becomes law until 38 states ratify it. All 27 of our amendments came through the first door. The second has never been opened.
In 1787, the Framers saw it coming.
In the Convention's final days, the draft of Article V left the amendment process entirely in Congress's hands. George Mason objected that if the government ever became oppressive, "no amendments of the proper kind would ever be obtained by the people." The delegates agreeed and added a pathway for states to call a convention. This second door exists because the Framers, fresh from revolution, expected a day when the people might need to act to fight an oppressive or ineffective government.
When Congress can't, or won't.
Congress hasn't proposed an amendment since 1978. Sometimes the cause is gridlock. Sometimes the need is a reform of that very body. Whatever amendment you believe the Constitution needs, the Framers left the final word with the people. Using that power is our right. Using it well — openly, safely, one subject at a time — is our responsibility.
No one has agreed on the process.
The text of Article V settles a few numbers — 34 states to apply, 38 to ratify — and leaves almost everything else unsaid. The Framers lived in a time rife with conventions, perhaps they assumed future generations would know, intrinsically, what to do. This was a fatal error.
The text answers almost nothing.
Who chooses the delegates, and how many? Does each state cast one vote, or does each delegate? Can a convention be subject-limited? Article V doesn’t say, and in this grey area, fear lurks.
States used to do this all the time.
Americans have held more than 230 state constitutional conventions, many of which succeeded in solving intractable problems. And where they failed, even more lessons were learned. The last one met in 1986. Our convention flexion needs exercising.
Someone is filling it.
We are not the first organization offering a path forward. The current most prominent convention sketch has been designed, deviously, to capture the convention for partisan aims. We are not the first, but ours is the most detailed, clear, and representative.
The rules for the most powerful untested process in American government should be established in the open, before anyone needs them — not on the fly.
One method, for any subject.
Mutable doesn’t choose the amendment or the issue. We do two things: we build the responsible, representative machinery any movement can rely on when it calls for an Article V convention, and we help Americans access and amend their founding documents — through conventions, referenda, and lobbying.
A rulebook any movement can adopt.
The Convention Handbook walks through an Article V convention from the first state application to ratification, taking a clear position at every step and setting it beside its strongest objection. Among what it settles:
- Representative from the start. Delegates are elected by voters, apportioned by population, and vote as individuals — one delegate, one vote — not as state blocs chosen by legislatures.
- Bound to the subject, free on the substance. Delegates stay on the question their state applied for, but no one hands them the answer. Within the subject, they deliberate.
- Democratic floor rules. Rules are adopted in the open on day one. Proposing an amendment takes a two-thirds vote, any delegate can invoke a rule to keep the convention on topic, and every vote is on the record.
- The logistics. Who hosts and who pays, how delegates are paid and credentialed, how elections get scheduled, how the press gets in, and how a month-long national gathering actually runs.
- Honest about what’s unsettled. Where the law hasn’t decided a question, the Handbook says so rather than pretending otherwise.
- A model state application. Standardized language any coalition can adopt, with the subject left blank, so that applications match and count.
- Convention standing rules. A ready-made rules package a convention can adopt, amend, or reject on its first day.
- A convention cost model. A working spreadsheet of what a convention would take in dollars, people, and time, nationally and state by state.
Relearning how to convene.
Americans once rewrote or amended their state constitutions regularly, holding more than 230 conventions since the founding. The last met in 1986. Our work in the states is about building that muscle back.
- Back convention calls. Every state provides for a constitutional convention, and fourteen ask their voters on a fixed schedule whether to hold one. We support those calls, and any Article V effort that commits to electing its delegates and working in the open. We don’t endorse the subject; we stand behind the process.
- Pass safeguards where we can. We offer model bills providing for popularly elected delegates, faithfulness to the subject, and open proceedings. They’re helpful, not required: a convention doesn’t wait on every state, and its floor rules and the ratification threshold protect the process regardless. In Connecticut, for example, if voters approve a convention in 2028, the state constitution leaves its makeup to the General Assembly, and we’ll push for the voters to choose its members.
- Demystify state constitutions. Most Americans have never read their state’s constitution, though it governs much of daily life and has been amended far more often than the federal one. We’ll run workshops, library talks, and classroom materials — in-person, as often as possible.
- Practice with citizens’ assemblies. We’ll partner with local organizations and movements to pilot randomly selected, representative panels that deliberate on constitutional questions, the model Ireland used before its constitutional referendums. It’s a way to build back that muscle memory.
Two opposing camps. While we thread the needle.
One movement wants a convention and has written undemocratic rules for it. Others want no convention at all, prefering to sit in fear. We ask both the same question: if a convention happens, how should it run?
The right idea, the wrong rules.
The most organized convention effort today is supported by the American Legislative Exchange Council (ALEC), an organization of state legislators and private-sector members that write model bills for statehouses. ALEC has published an Article V handbook for state lawmakers, and drafted model rules for the convention itself. Those rules put state legislatures in charge at nearly every step. We oppose them for three reasons.
Leadership at ALEC has stated that they do not like it when people vote becasue the results tend to hurt their special-interest benifactors. Their handbook is crafted to acheive a desired outcome, even if it conflicts with the will of the people.
Mutable welcomes any movement to adopt our Article V Convention Handbook. In doing so, you are promoting order and substance over partisan politics and ensuring that representative democracy wins the day.
A fear worth answering.
Some of the strongest voices against a convention belong to organizations we respect. We don’t ask them to want one. We ask them to consider what they’d demand if one came anyway. Their case rests on three warnings:
We don’t need skeptics to love conventions, or champions to give up theirs. We are creating a standard the American people can rely on to ensure their voices are truly heard the loudest: a standard a convention’s supporters can adopt, its opponents can demand, and the country can trust when the day does comes.
Building in real time.

Convention Standing Rules
In developmentProposed rules for how the convention itself would run — day-one administration, voting structure, strict limits on scope, and procedures that keep it from wandering. The procedural backbone that makes a limited convention real rather than theoretical.
Model State Application
In developmentThe resolution a state legislature passes to apply for a convention limited to a single subject, with the subject left for each coalition to fill in. The wording carries enormous weight — too loose and it risks an open convention, too rigid and states can’t align.
The Faithfulness Act
In developmentA model state law binding the delegates a state sends — holding them to the single subject while, crucially, leaving them free to deliberate over the substance. The mechanism that turns “we promise to stay narrow” into something enforceable.
Modeling the Cost
