# 2015 Taiwanese legislative by-elections

The 2015 Taiwanese legislative by-elections were held on 7 February 2015 in Taiwan to elect 5 of the 113 members of the Legislative Yuan for the remaining term until 2016. No change in the party composition of the Legislative Yuan resulted from the by-elections; three Democratic Progressive Party candidates won the seats vacated by DPP legislators, and two Kuomintang candidates won the seats vacated by KMT legislators.

## Background

The by-election was the result of resignations by Kuomintang legislator Hsu Yao-chang from Miaoli County's 2nd district; Lin Chia-lung, Democratic Progressive Party legislator for Taichung City's 6th district; Wei Ming-ku, Democratic Progressive Party legislator for Changhua County's 4th district; Lin Ming-chen, Kuomintang legislator for Nantou County's 2nd district; and Pan Men-an, Democratic Progressive Party legislator for Pingtung County's 3rd district.
Hsu Yao-chang, Wei Ming-ku, Lin Ming-chen, and Pan Men-an won their elections for county magistrate, and Lin Chia-lung won his election for mayor in the 2014 local election. Under the Article 73 of the Civil Servants Election and Recall Act [zh], if any positions become vacant due to resignation or election to another office, and the vacated term is longer than one year, a by-election shall be completed within three months commencing from the date of resignation.
On 5 December 2014, the Central Election Commission announced that by-elections for Taichung 6 and Changhua 4 were to be held on 7 February 2015. Candidate registrations for the two seats were open from 22 to 26 December 2014. On 26 December 2014, the CEC announced that the by-elections for Miaoli 2, Nantou 2, and Pingtung 3 were to be held on 7 February 2015 as well. Candidate registrations for these three seats were open from 26 December 2014 to 9 January 2015.
