Substantial changes of oversight regulations impact on oversight functions. The change occurred for four times in 1969, 1999, 2003, and 2009. It could be happened because of the amendment of Organization and the Position of Representative Institutions Act. In every amendment, the acts strengthen the oversight functions, such as add the duties, authority, and the rights. It also adds obligations to the Parliament to strengthen its oversight function. All of these acts rule the Parliament to oversight the executive regarding to the implementation of acts, budget and government policy.
