On 4 February 2005, Chen was indicted for electoral fraud. He was accused of buying votes for his daughter, Chen Ying, in the legislative election held three months prior. Chen denied the accusations, but he nevertheless resigned from his position as chairman. He was replaced by Walis Pelin. In 2007, Icyang Parod became chairman, and he was succeeded by Chang Jen-hsiang the next year. Chang was criticized by both indigenous people and legislators of all ethnicities. Indigenous protesters outside the Council building demanded Chang resign, saying that she had disregarded the land and hunting rights of indigenous peoples. Protesters claimed Chang allowed the Atomic Energy Council to dump nuclear waste near indigenous villages, and that the government would not let the Puyuma people participate in its traditional annual hunt without permission from the Forestry Bureau. Kao Chin Su-mei, an Atayal legislator, criticized Chang at the same time. Chang was later criticized by several other lawmakers, who questioned her effectiveness in her position, as well as her commitment to securing autonomy for indigenous peoples.
