*146. Rules.*--The rules governing debate and decorum are not only elaborate but, in some instances, of great antiquity. In so far as they have been reduced to writing they may be said to comprise (1) "standing orders" of a permanent character, (2) "sessional orders," operative during a session only, and (3) "general orders," indeterminate in respect to period of application. In the course of debate all remarks are addressed to the Speaker and in the event that the floor is desired by more than one member it rests with the Speaker to designate, with scrupulous impartiality, who shall have it. When a "division" is in progress and the doors are closed members speak seated and covered, but at all other times they speak standing and uncovered. A speech may not be read from manuscript, and it is within the competence of the Speaker not only to warn a member against irrelevance or repetition but to compel him to terminate his remarks.[205] A member whose conduct is reprehensible may be ordered to withdraw and, upon vote of the House, may be suspended from service. Except in committee, a member may not speak twice upon the same question, although he may be allowed the floor a second time to explain a portion of his speech which has been misunderstood. Undue obstruction is not tolerated, and the Speaker may decline to put a motion which he considers dilatory. [Footnote 205: On parliamentary oratory see Graham, The Mother of Parliaments, 203-224.] *147. Closure and the Guillotine.*--For the further limitation of debate two important and drastic devices are at all times available. One is ordinary closure and the other is "the guillotine." Closure dates originally from 1881. It was introduced in the standing orders of (p. 140) the House in 1882, and it assumed its present form in 1888.[206] It sprang from the efforts of the House to curb the intolerably obstructionist tactics employed a generation ago by the Irish Nationalists, but by reason of the increasing mass of business to be disposed of and the tendency of large deliberative bodies to waste time, it has been found too useful to be given up. "After a question has been proposed," reads Standing Order 26, "a member rising in his place may claim to move 'that the Question be now put,' and unless it shall appear to the Chair that such motion is an abuse of the Rules of the House, or an infringement of the rights of the minority, the Question 'that the Question be now put' shall be put forthwith and decided without amendment or debate." Discussion may thus be cut off instantly and a vote precipitated. Closure is inoperative, however, unless the number of members voting in the majority for its adoption is at least one hundred, or, in a standing committee, twenty.
