Whether Ohio could require the General Assembly’s ratification of a proposed federal constitutional amendment to be submitted to the people through a state referendum.
Holding
No. Article V requires ratification by state legislatures or state conventions, as Congress selects, and Ohio could not add a popular-referendum requirement to legislative ratification.
Reasoning
Article V creates a complete national process for constitutional amendment. Congress may propose an amendment, or call a proposing convention on application of two-thirds of the state legislatures, and Congress chooses whether the states will ratify through their legislatures or through conventions. Because Congress selected legislative ratification for the Eighteenth Amendment, ratification had to occur through that constitutionally prescribed method.
The Constitution’s reference to state “Legislatures” means the representative lawmaking bodies of the states. At the founding, that term had a settled meaning, and the Constitution consistently distinguishes action by a legislature from direct action by the people. Where the Constitution meant to require popular action, as in the selection of House members, it used language expressly calling for election by the people.
The framers could have made constitutional amendments subject to direct popular vote, but they instead chose deliberative bodies—state legislatures or state conventions—as the two permissible ratifying institutions. State officials, legislatures, and courts cannot alter that federal choice by imposing another step, even one authorized by the state constitution.
