This is perhaps the clearest statement by the Founder called by some the father of the Constitution that an Article V application properly organizes an Article V convention to propose a specific amendment. In 1799, Madison defended the legislative declarations of Virginia and Kentucky that the Alien and Sedition Acts were void and unconstitutional. He said they were statements of opinion to which states are entitled. But he didn't stop there. He emphasized how the states should consider following up their declaration with an Article V application to obtain an Article V convention for the object of proposing an "explanatory amendment" that the Alien and Sedition Acts were unconstitutional.
The modern notion that an Article V convention sets its own agenda and drafts any number of amendments independently of the will of the States as expressed in their Article V application is obviously, manifestly and completely alien to Madison's expressed public understanding of the process.
