The Constitutional Convention has handed its report on Dáil reform to the library of the Houses of the Oireachtas.
The convention met over two weekends in May and June to report recommendations on possible amendments to the Dáil electoral system.
Amongst its recommendations are the retention of the current Single Transferable Vote system, while increasing the size of constituencies.
Convention Chairman Tom Arnold said the report must now be considered by the houses of the Oireachtas.
Speaking on RTÉ’s News at One, Mr Arnold said: "Each report that the convention produces is laid in the houses of the Oireachtas, the Oireachtas must debate that within four months.
"And it is up to the Government to make a decision as to whether or not to proceed to a referendum or not.
"Obviously, if any of these reports are recommending changes in the Constitution they ultimately have to be passed by the people in a referendum."
