On May 27, 1992, several other amendments were passed (known as the "Second Revision"), most notably that allowing the direct election of the President of the Republic of China, Governor of Taiwan Province, and municipal mayors. Ten new amendments to replace the eighteen amendments of the First and Second Revisions were passed on July 28, 1994. The amendments passed on July 18, 1997 streamlined the Taiwan Provincial Government and granted the Legislative Yuan powers of impeachment. The constitution was subsequently revised in 1999 and 2000, with the former revision being declared void the same year by the Council of Grand Justices. A further revision of the constitution happened in 2005 which disbanded the National Assembly, reformed the Legislative Yuan, and provided for future constitutional change to be ratified by referendum.
