As far as I am aware, while the dual mandate in England is not utilised by custom, it is not prohibited by law. Members of the Scottish Parliament and Welsh Assembly can hold a dual mandate as Members of the United Kingdom Parliament. If the Dáil becomes increasingly busy it will become the practice for Deputies not to hold a dual mandate. That has happened in the European Parliament where Members have chosen not to hold a dual mandate, but there is no legal prohibition. That is the correct way to proceed. The issue should not be addressed by way of legislation.
