The Ohio Ballot Board is a committee that writes the official ballot language for questions submitted statewide in Ohio.
The board consists of the Ohio Secretary of State and four appointed members, no more than two of whom shall be from the same party. One is appointed by the President of the Ohio State Senate, one by the minority leader of the Ohio State Senate, one by the Speaker of the Ohio House of Representatives, and one by the minority leader of the Ohio House. Members hold four-year appointments. A vacancy is filled in the same manner as the original appointment and must be filled with a person from the same party as the former member. The Secretary of State is the chairman and has the same vote as each of the other members. Three members of the board are a quorum.
The board prepares information on statewide questions and distributes it through boards of elections and public libraries.
