One of the more important functions of the House is its critical review function. This includes scrutiny of the Executive Government, bringing to light issues and perceived deficiencies or problems, ventilating grievances, exposing, and thereby preventing the Government from exercising, arbitrary power, and pressing the Government to take remedial or other action. Questions are a vital element in this function.
It is fundamental in the concept of responsible government that the Executive Government be accountable to the House. The capacity of the House of Representatives to call the Government to account depends, in large measure, on its knowledge and understanding of the Government’s policies and activities. Questions without notice and on notice (questions in writing) play an important part in this quest for information.
