Legislators met biennially until a 2008 ballot initiative created annual legislative sessions. In 1992, voters approved term limits of two four-year terms. In 2014, term limits were extended to 16 years cumulative in either house. In 2020, voters approved a constitutional amendment changing terms limits to 12 consecutive years with the opportunity to return after a 4 year break. This change only effects legislators elected after the November 2020 elections. Legislators elected in the November 2020 elections or earlier can serve 16 years consecutively or non-consecutively and return once 4 years have passed from their last term expiring.
