Fiji's fourth constitution was signed into law by President Ratu Epeli Nailatikau on September 6, 2013, coming into effect immediately. It is the first to eliminate race-based electoral rolls, race-based seat quotas, district-based representation, the unelected upper chamber, and the role of the hereditary Council of Chiefs. It vests sole legislative authority in a single-chamber, 50-seat, at-large Parliament, to be first convened following general elections in 2014. It is also the first ever to grant the right to multiple citizenship (in effect since 2009 by decree, on abrogation of the 1997 constitution), and lowers the voting age to 18.
