 Shih, a former political prisoner, has vowed to demonstrate indefinitely outside the presidential office, even until March 2008, when Taiwan (Republic of China) is due to hold the next presidential election, or until Chen, also a former political prisoner, resigns.However, in December 2006 Shih went back on this pledge, instead retiring to an apartment near the train station and promising to remain there until Chen's term was over.On 14 October 2006, the Taipei Police repealed Shih's petition for further protest on Ketagalan Avenue because the protests on 10 October 2006 had violated the city law.
