Unlike the Parliamentary system, the concept of 'question hour' or 'question time' doesn't really exist in the American legislature. Here's an interesting report done by the Congressional Research Service on the possibility of a question time in the US. From our point of view, the report is interesting because it reviews the existing provisions for a Parliamentary Question Time in different countries (India isn't mentioned), and considers the pros and cons of such a system. The report concludes: "Whether the question period would be successful in a system of separated powers depends in large part on the attitude of its participants and on the format the question period ultimately assumes. The question period has the potential of involving more rank-and-file Members in the policy-making process, and improving the means of communication between executive departments and the Congress. It also could harden relations between the Congress and the Executive, and might increase the level of partisan controversy in Congress." There's even an online petition among a few american bloggers to push for a question time in the US. Read about it here. In this country of course, parliamentary questions are an established feature of the work of Parliament. Parliamentary questions cover a huge range of topics and can be an mine of information and data about government policy. The Lok Sabha and Rajya Sabha sites put the complete text of all parliamentary questions (and the responses to them) online.
The convention for passing Bills in the Parliament is by orally communicating agreement or disagreement with the proposed motion (whether a Bill should be passed or not, for example). When a motion is put to vote the speaker says, 'Those in the favour of the motion say Aye and those opposing it say No.' According to the voice vote, the Speaker decides whether the Bill is accepted or negated by the House. If a member is not happy with a voice vote, it can be challenged and a division can be asked for. The procedure for division entails the Speaker to announce for the lobbies of Parliament to be cleared. Then the division bell rings continuously for three and a half minutes and so do many connected bells all through Parliament House and Parliament House Annexe. MPs come from all sides into the chamber and the doors are closed. The votes are recorded by the Automatic Vote Recording Equipment. For example, in the Winter Session of the Parliament, four appropriation bills (financial Bills) were passed by voice vote amidst the interruptions from the opposition and two bills i.e. The Orissa (Alteration of Name) Bill, 2010 and The Constitution (One Hundred and Thirteenth Amendment) Bill, 2010 (Amendment of Eighth Schedule) were passed through division. For these Bills the voting took place together. The votes recorded were: 298 ayes and 0 noes.
