2008 Tsengian constitutional crisis

The 2008 Tsengian constitutional crisis was an event that started on February 2, 2008, when president of the National State Assembly (NSA) Li Zheng-qing resigned. A week later, Tsengian president James Huang appointed Victor J. Cheng, a socialist, as president, which caused outrage since the president of the NSA must be elected by a majority of the NSA. Huang justified his actions by saying that an amendment of the constitution in 2007 allowed the president of to appoint the president of the NSA "under extraordinary circumstances". At the time, Huang had invoked a state of emergency due to peaceful protests after he and his government were discovered to have taken bribes from overseas businessman, mainly Chinese, in exchange for votes, foreign influence in Tsengian companies, and Huang's administration's personal use. Added with the sex scandal, in which adult tapes of Huang and several high-ranking NPP politicians were discovered in April 2008, this only increased the amount and the violence of protests.

The crisis ended on May 8, 2008, when Huang resigned from his post. Several members of his government resigned in the days after. Marc Tseng, the newly-elected president of the NSA, became president, and narrowly won the 2008 election held in July. The 2008 election was the first election since 1976 to include a People's Democratic Party (PDP) candidate. The crisis is seen as the end of National Prosperity Party (NPP)'s dominance in Tseng, although its influence started to wane in the 1990s.
