<P> A Half - an - Hour Discussion can be raised on a matter of sufficient public importance which has been the subject of a recent question in Lok Sabha irrespective of the fact whether the question was answered orally or the answer was laid on the Table of the House and the answer which needs elucidation on a matter of fact . Normally not more than half an hour is allowed for such a discussion . Usually, half - an - hour discussion is listed on Mondays, Wednesdays and Fridays only . In one session, a member is allowed to raise not more than two half - an - hour discussions . During the discussion, the member, who has given notice, makes a short statement and not more than four members, who have intimated earlier and have secured one of the four places in the ballot, are permitted to ask a question each for further elucidating any matter of fact . Thereafter, the Minister concerned replies . There is no formal motion before the House nor voting . </P> <P> Members may raise discussions on matters of urgent public importance with the permission of the Speaker . Such discussions may take place on two days in a week . No formal motion is moved in the House nor is there any voting on such a discussion . </P> <P> After the member who initiates discussion on an item of business has spoken, other members can speak on that item of business in such order as the Speaker may call upon them . Only one member can speak at a time and all speeches are directed to the Chair . A matter requiring the decision of the House is decided by means of a question put by the Speaker on a motion made by a member . </P> <P> A division is one of the forms in which the decision of the House is ascertained . Normally, when a motion is put to the House members for and against it indicate their opinion by saying "Aye" or "No" from their seats . The Chair goes by the voices and declares that the motion is either accepted or rejected by the House . If a member challenges the decision, the Chair orders that the lobbies be cleared . Then the division bell is rung and an entire network of bells installed in the various parts and rooms in Parliament House and Parliament House Annexe rings continuously for three and a half minutes . Members and Ministers rush to the Chamber from all sides . After the bell stops, all the doors to the Chamber are closed and nobody can enter or leave the Chamber till the division is over . Then the Chair puts the question for second time and declares whether in its opinion the "Ayes" or the "Noes", have it . If the opinion so declared is again challenged, the Chair asks the votes to be recorded by operating the Automatic Vote Recording Equipment . </P>
