Candidates for each constituency are chosen by the political parties or stand as independents. Each constituency elects one member under the first past the post system of election. Since Nepal uses a parallel voting system, voters cast another ballot to elect members through the party-list proportional representation. The current constitution specifies that sixty percent of the members should be elected from the first past the post system and forty percent through the party-list proportional representation system. Women should account for one third of total members elected from each party and if one-third percentage are not elected, the party that fails to ensure so shall have to elect one-third of total number as women through the party-list proportional representation.
