The 2004 Taiwanese legislative election was held on 11 December 2004. All 225 seats of the Legislative Yuan were up for election: 168 elected by single non-transferable vote, 41 elected through party-list Proportional representation, eight elected from overseas Chinese constituencies on the basis of the proportion of nationwide votes received by participating political parties, eight elected by popular vote among the aboriginal populations. Members served three-year terms beginning on 1 February 2005, and ending 31 January 2008. The next term served four years.
This was the first election following Pan-Blue coalition candidate Lien Chen's narrow defeat in the presidential election in March. With the results of the presidential election still contested, many saw the legislative election as a referendum on Chen Shui-bian's Government and on the Pan-Blue Coalition's electoral viability. With the failure of the Pan-Green Coalition to win a majority, President Chen Shui-bian found it difficult, as in the past, to enact his policies.[citation needed]
