In a nonpartisan system, no official political parties exist, sometimes reflecting legal restrictions on political parties. In nonpartisan elections, each candidate is eligible for office on his or her own merits. In nonpartisan legislatures, there are no typically formal party alignments within the legislature. The administration of George Washington and the first few sessions of the United States Congress were nonpartisan. Washington also warned against political parties during his Farewell Address. In the United States, the unicameral legislature of Nebraska is nonpartisan but is elected and votes on informal party lines. In Canada, the territorial legislatures of the Northwest Territories and Nunavut are nonpartisan. In New Zealand, Tokelau has a nonpartisan parliament. Many city and county governments[vague] are nonpartisan. Nonpartisan elections and modes of governance are common outside of state institutions. Unless there are legal prohibitions against political parties, factions within nonpartisan systems often evolve into political parties.
