what is the process for ratifying amendments
See the Ratification Convention Page for a discussion of the make up of a convention. Amendments are sent to the legislatures of the states by default. Only one amendment, the 21st, specified a convention. In any case, passage by the legislature or convention is by simple majority. The Constitution, then, spells out four paths for an amendment: 1  Proposal by convention of states, ratification by state conventions (never used). 2  Proposal by convention of states, ratification by state legislatures (never used).
