Question Hour is one of the most significant items of business in parliamentary proceedings and it gives the whole institution of Parliament the great significance it possesses. This Hour has assumed high importance in legislatures because of Government's heavy involvement in matters affecting the day-to-day life of the citizens for which Ministers are collectively and severally answerable to the people. Asking questions is a refined parliamentary device. Questions are asked primarily to elicit information, to ensure accountability, and for exercising a kind of legislative control over executive actions

Answers to questions have to be precise and accurate. The information given through the answers has a high presumption of authenticity and wrong or inaccurate answers can be construed as an attempt to mislead the House, leading to raising of questions of privilege. If it is later found that the information supplied bona fide is inaccurate or incorrect, the Minister has to make a statement in the House correcting the previous answer in case it is a starred question or lay a statement on the Table of the House in the case it is an unstarred question.

Where Ministers feel that they cannot supply complete and accurate information at the moment, they can and generally ask for time in respect of that portion of the question and assure the House to supply it as soon as it is available. Such assurances are closely monitored by the Committee on Government Assurances.
