The constitution requires a membership of between 30 and 50. The first Unicameral in 1937 had 43 members. A 1971 law increased membership to the current size of 49. The population of a legislative district is about the same as the population of a Minnesota House district. Four year, overlapping terms.
Terms are four years.
Terms overlap, so that half the terms expire every two years. Terms are not limited. Several attempts to limit terms have been overturned by the Nebraska courts. The amount is specified in the constitution. This is the federal rate for Lincoln.
