Background - The National Assembly is a legacy from the former dual parliament system, in which the assembly used to elect the president and amend the constitution, while the Legislative Yuan handled lawmaking. - The assembly used to be elected every six years until its powers were gradually taken away. Direct presidential elections began in 1996, leaving the assembly with its constitutional amendment duties and the right to impeach the president. - In 2000, the assembly voted to make itself inactive to pave the way for its eventual abolishment. Candidates - Twelve parties and groups are fielding 688 candidates for 300 seats - Votes are cast for parties and groups, not for individuals. Seats will be allocated based on the proportion of votes each party or group gets. - Each party has to specify its position on amendments, and each elected candidate must vote according to party line. - Five groups including the two biggest parties - the ruling Democratic Progressive Party and the opposition Kuomintang - support the amendments as they favour bigger parties.
