(c)

Unless provided otherwise by law, convention calls are to conform as nearly as possible to the act calling the 1955 convention, which provided for a legislative vote of a majority of members elected to each house and ratification by a majority vote on the proposals. The legislature may call a constitutional convention at any time.

(d)

In these states, the legislature may call a convention without submitting the question to the people. The legislative vote required is two-thirds of the members elected to each house in Georgia, Louisiana, South Carolina and Virginia; two-thirds concurrent vote of both branches in Maine; three-fourths of all members of each house in South Dakota; and not specified in Alaska, but bills require majority vote of membership in each house.

In Florida, conventions can be called by filing an initiative petition with signatures equal to 15 percent of the votes cast in the preceding presidential election and also equal to 15 percent of signatures in half of the congressional districts in the state and then obtaining a majority of the voters at the ensuing election.
